- Problem with IN parameters to an Oracle stored procedureHello all
I had earlier posted the same problem I am having on
comp.java.lang.programmer earlier and someone suggested this post
would probably fall better under this group. Here is the link to the
original post with the original post copy pasted below.
http://groups.google.co.in/group/comp.lang.java.programmer/browse_thread/thread/b0b845981c3e403a/#
Since then I have changed the IN parameter to my stored procedure to
read as
clID IN TABLEA.CLIENTID%TYPE
instead of clientID, based on a suggestion to the earlier post and
have still had no luck.
Any suggestions are welcome.
Thanks

- Beans with JSFI'm pretty new to programming with JSF and beans, and have been
reading up the documentation in the book "Core JavaServer Faces"
by D.Geary and C. Horstmann as well as online, and managed to
get some simple programs to run, so at least I now understand
some of the basics.
However, I've got quite a lot of existing code in HTML and
JavaScript that works, although not fully cleaned up yet, and I want
to make as few changes as possible in order to modify it for using
beans with JSF. Specifically, some months ago I wrote some
client-side code which is backed up online at
http://csharp.com/simulator/simulator.html, which I'm in the process
of modifying for JSF. The links at the bottom take you to
.../option1.html and .../option2.html, with the original source code
at
respectively .../option1.txt and .../option2.txt. At the moment the
code is not linked to code on a server, so only the JavaScript works
with the forms.
The index page didn't need much work, with the main change being
to include the JSF tags at the top (I'm leaving work on the counter
until later). The option1 page is mostly one large form, and what I
have since done is to keep the form as it is, except that it only
operates with JavaScript, with the post, action, and JavaScript
function calls at the beginning removed, together with the "Submit"
and "Reset" buttons at the end. I put these two buttons together
with calls to the JavaScript in a JSF form immediately below the
end of original form, and after making a few changes to the
JavaScript, got the JavaScript to work correctly and validate the
form.
My question is how do I send to the server the contents of the
original form, including the hidden fields? Do I have to create a
hidden field in the JSF form for each value entered in the main form,
and create a bean for each of these values, or is there some way
of sending the whole contents of the form to a bean, which can then
parse the values. I want to avoid turning the original form into a
JSF form, as it would probably mean making many changes to the
JavaScript, which would require extra work and debugging.
Exactly the same will be done with the option2 page once option1
has been sorted out, and I would be most grateful for some advice.

- want to sort tables inside a complex mechanism, what can be the approach?I have a situation where first we are fecthing some ids(list of say
version ids using hibernate form database)
then keeping those list of data in a Pager Object(Paging mechanism
displays 100 rows per page out of complete sa 100 or so.)
This pager class does two things one takes whole list of ids
(Collection of version_id).
(Every time based on search criteria it changes. For searching in
hibernate values are hardcoded. Want modification with minimal changes
as many things are interrelated here.)
and other thing it checks no. of contents based on that displays data
per page(100 here).
It means stores all data from database and send it oage by page.(First
thing to notice)
Next all this is getting stored in Report page where it searches other
column names based on ids(version_id) the other column names are
getting changed for different requests so what we do is take all other
columns collectAllExtraFields(this is also getting changed everytime
based on what is getting searched.)
Now all this is getting accumulated while displaying but as we know
what to display we hardcoded all fields required to display based on
search. But all fields are searched based on the id fetched from
database first time which Pages is storing.
like this
Search for product user information & retrun results in the form of a
paged table for components used by specific product
ComponentVersion versionObj =
versionHandler.getComponentVersion(versionId);
String CAUsers = ctHelp.getCAUsersSection(versionId);
tableBody = tableBody + ((i%2 == 0) ? "<tr
class='table_banded_row' valign='top'>" : "<tr class='table_row'
valign='top'>");
tableBody = tableBody + "<td class='table_data'>" +
procHelper.getCompVersionLink(versionId,
versionObj.getCompName(), versionObj.getCompVersion()) + "</td>";
tableBody = tableBody + "<td class='table_data'>" +
CAUsers + "</td>";
tableBody = tableBody + "<td class='table_data'><span
class='data'>" +
versionObj.getComponent().getType() + "</span></td>";
tableBody = tableBody + "<td class='table_data'><span
class='data'>" +
versionObj.getComponent().getVendor() + "</span></td>";
tableBody = tableBody + "<td class='table_data'><span
class='data'>" +
versionObj.getRecommendationType() + "</span></td>";
tableBody = tableBody + "</tr>";
/** Get ComponentVersion ID with hyperlink to ComponentVersion Detail
page
*/
public String getCompVersionLink(long versionId, String compName,
String compVersion){
return "<a class='datalink' title='" +
this.getComponentFlyOverText(versionId) + "'
href='/techstacks-v2_1/content/components/componentDetail.jsp?versionId="
+ versionId + "'>" + compName + " " + compVersion + "</a>";
}
this is getting called by Report.jsp to display.
As this is getting changed everytime its called form classes not used
in jsp directly i think.
Now original objective is to sort all these displayed columns.
If user clicks on any of the column name everything sholud get sorted
on that basis.but sholud not call databse for same again by using same
id and mapping with any new column name this sholud be done. Paging
mechinasm to be used as it is if possible without major changes.
i don't know where to start with as started looking on this code just
2-3 days back only.

- History of objects?Hi
a relatively complex project I am working on now has a need for
"versioning". I mean, we have a system for administration of data (creating
and updating) in a database, and this data needs to be saved as separate
versions each time it is updated - a lot like a CVS.
The data is in the main "bridges", which have lots of data (name, location,
height etc), and lots of related data: persons (controller, supervisor);
tasks to be performed...
It should for example be possible for a user to view a "bridge" as it looked
on a certain date in the past, with all its related data (as they also were
at that date).
Does anyone have some good ideas about how we can save a history of versions
of all our objects? Where can I start to look for good ideas? Could we use
CVS via some sort of java api?
Thanks,
Peter

- Play audio clip in an ApplicationI'm trying to play an audio clip by using Applet's newAudioClip()
method. That method takes a URL. The .wav file is located in a jar file
(the only jar file). For example:
if myJar.jar is the only jar file
"java -jar myJar.jar" launches the application correctly and everything
is wonderful. My audio clip won't play because I don't know how to
access the .wav file from the jar file.
This code snippet works fine when I'm not running from the jar file:
try
{
File currentDir = new File(".");
URL currentDirURL = currentDir.toURL();
URL url = new URL(currentDirURL, fileName);
AudioClip clip = Applet.newAudioClip(url);
clip.play();
}
catch (Exception e)
{
e.printStackTrace();
}
It knows to look for the sound file in the current directory. How do I
adjust this code to look for the sound file in the jar.
I have a feeling it's an easy answer involving class.getResource().....

- writing java daemon server: start and stopDear everyone,
I am trying to write a server program to do some monitoring.
I am using Windows 2000 platform.
I've seen that there is some server program can start server by
specifying command like "server start" and stop it like "server stop".
I am wondering how to do it in java language since java is running in
the JVM.
1. Is it prossible to send signal to kill the process just like c lang
?
2. Do java have process ?
3. How about if java thread can be killed by those deprecated method
like thread.stop(), can I find the current running thread and stop it
?
4. Any suggested method to do the server stop which can stop the
current running java program in JVM ?
Thank you for helping

- Send ARPHello everyone,
I want to verify if an IP is in my local net or not.
If I send an ARP request and get a MAC from that then the IP is in the
local net.
That's why I need to send an ARP request in Java under Windows XP and
NT.
Can anyone tell my how this is done?
Doing this native with the Windows iphlpapi.dll seems to be a bit
complex.
Any ideas for any easy way?
Thanks.

- List helpHi,
I am new to Java.
I've been working on this project for some time now and I cannot get it
to work.
This is supposed to be a linked list.
I need to use an insert method that alphabetically adds a new title to
the list. This code I have here doesn't have a working compareTo method
but only a test to add node to the list.
This code was provided to me and I must add an insert that will put a new
item in alphabetically order. Don't tell me the answer - I just don't
understand why this doesn't work. I hope that what I've written here is
clear.
Thanks
John
Main looks like this something like this:
main(String [] args){
BookList book = new BookList();
book.add (new Book ("title of book"));
}
// ----------------Test compareTo
public int compareTo(Node a, Node b){
// Since I couldn't get this to work either, I test to see if I can get
any value.
println(a.book.compareTo(b.book)); // doesn't work I don't know how to
compare the titles
return 0;
}
public class BookList
{
private BookNode head;
//----------------------------------------------------------------
// Sets up an initially empty list of books.
//----------------------------------------------------------------
BookList()
{
head = null;
}
//----------------------------------------------------------------

public void insert (Book newBook){
BookNode node = new BookNode (newBook);
BookNode current;
BookNode prev;
if (head == null)
head = node;
else
{
current = head;
while (current.next != null){
// Orignally this method looped through the whole list until it found the
end, then add the new
// to the bottom.
// I did a test here to see if I could move the list around.
// This is what I think should happen: save current in prev. get next with

// error. I just can't figure this out.
prev = current;
current = current.next;
node.prev = current.prev;
node.next = current;
node.prev.next = node;
current.prev = node;

- Opportunities in U.K./Great Britain?I have a friend who recently moved to Madrid. He had a Dutch passport
so EU access was relatively easy for him. We both lived in D.C., but
I remain US citizen by birth.
My question is, he says it's becoming more popular for J2EE
development in Great
Britain and the UK. I'm wondering how good is the market? (in
relation to US) How good is it for US programmers? (any demand for US
borne skills) And if any of these are true, how hard it is securing
work permit? (etc) Finally is there any idea what standard of living
might be like?
Given all of this would there be sacrifices, or would it just be
better overall simply to stay in US?

- Help with JavaPOS pleaseHi there,
I have made an application that uses a POS printer device to print out a
receipt,
but there are genereal problems printing out .....
sometimes it prints out sometimes it doesn't (??) this is not the most major
of the
problems. The most major problem has to do with setting the style and the
layout of the printing.
After I have opened my device, claimed it everything should be ready or ??
I have checked to see what the method getFontTypefaceList()); returns
and my guess was that these numbers return different numbers that are
representatives for character sets eg fonts!!!! So I take one of these
numbers to try it out, put a number inside the method setCharacterSet(850);
yes .. 850 for instamce ... then I restart my application to see if the
output
is different, but it is not. I wonder why.
and yes I have tried several other methods in the POSprinter class and
by means of the POSprinterConst class too.
Does anyone have any experience with this or am I left to keep
experimenting?
I also need to find out how to set Linebreaking, linedistancing etc etc bold
italic and so on.
Regards
Carl

Can you give proof that this really is your hot spot? Most guesses

Anyway I find it hard to believe that arraylist is 10 times slower
since the methods (get and set) does something like
{ RangeCheck(index); return elementData[index]; }.
Ok the range check is unneccasry, it will be checked by the jvm also.
If you use add a lot then it will check the size of the array and
expand if neccessary. If you know in advance how many objects you will
store this should not be a problem (you do create the list with the
size), if you dont know in advance it will be hard to write something
that is a magnitude faster...

Enough is enough. It is /not/ a requirement that someone must google

I actually dislike Java's way of disallowing code that is otherwise
perfectly legal, but will never be executed. I also dislike Java's way
of disallowing statements that can't possibly have side effects. One of
my general principles (although not a rule set in stone) is that
languages should never have explicit "exceptional" conditions just to
disallow code that would otherwise be perfectly legal and harmless.
Such explicit conditions feel like bondage-and-discpline language to me,
and I prefer my bondage-and-discipline among humans, thank you very
much. =)

- How to convert a C++ Object to a JNI jobject in order to use GetObjectClassI have an interface object of type ISubscribe and I am trying to cast
the ISubscribe object to a jobject so I can call GetObjectClass in
order to proceed with a callback using JNI.
ISubscribe * s
jclass cls = env->GetObjectClass(s);
Does anyone know how I can do this in C++? I tried using
reinterpret_cast<jobject>(s) but GetObjectClass does not like that. Any
ideas would be appreciated.

- [encoding]Stupid question regarding encodingI have written a java plugin for an application that reads a file to execute
a series of actions ; when I parse my text file I check for the existence
of the following line "#HEADER" ; it works fine on my equipment ; on
Windows somebody working with the text file encoded in utf-8 told me that
there is problem as the line containing "#HEADER" is not found !
Now I am a little bit puzzled about all this :
(a) when you write java code and compile it what happens to the
string "#HEADER" because it will be used in the following test :
if (line.equals("#HEADER") {...}
where line is read from the text file with encoding as is on the machine
where the class is executed ? in other words you are comparing what to
what ?
(b) when with a Java app you read a text file can you get its encoding
format like utf-8 or ANSI or whatever to decide about some actions to be
taken ?
I think the problem could be easily solved by replacing "#HEADER"
by "_HEADER" but I have to go to the bottom of this to understand what is
going on.

- Ultimate enterprise design pattern for 3 tiered appsSo, I feel I am close here is what I have so far.
Goal: Database driven selection of controls on forms
Goal: Business rules only aware of interfaces
Goal: Presentation layer only aware of interfaces
Database Table Person: Name, BirthDate, Gender, CreateDate, CreatedBy
Value Object:
public class Person {
private String name;
private DateTime birthDate;
private int gender;
private DateTime createDate;
private int createdBy;
}
Business Layer Object:
public interface IPersonModel {
public boolean isTeenager();
public boolean isMale();
public boolean isFemale();
}
Presentation layer Multi Column List control
public interface ITableList {
public int rowCount();
public Object getItemAtRow(int row);
public Object getValueAtRowColumn(int row, int column);
}
public interface ITableItem {
public Object getValueAtColumn(int column);
}
The most complex part is storing in a database table which fields on
the value object will be presented in the multi column list control.
It needs to be user friendly and maintainable.
One time I tried having each value object with a switch statement for a
unique number for each field. So the database contents and source code
are kept in synch e.g. 266 in the database means 'Person CreateDate'
and the value object returns that when implementing ITableItem.
It worked but relies on a code generator to make it all work.
This time around I thought I could keep a script in the database so the
user would pick the first column to be person.getCreateDate(), the
second to be person.getName() etc.
Using reflection I could generate on the fly which attribute will be
displayed in which column.
Anyone think of other options?
The other thing I need to change is it seems an unecessary dependency
for the value object to implement ITableItem - there probably needs to
be another class which does it and depending on the database values
pulls the data from the value object.
The same goes for the value object implementing the business rules.
While probably not too bad if it does, perhaps mapping the values to
something that does might work better.
Apart from the value object I am trying to anything else in all the
code knowing about fields which are only used for CRUD e.g. createDate.
CreateDate may never be used for logic - in my app - ever - so why
pass it around as business objects - better to only have things
implementing interfaces where needed.
What do you think so far?

- mouseClicked vs. mousePressed on Apple vs. WindowsI'm writing a Swing component which must function similarly on Apple
and Windows; and am having trouble with which event to fire off of
(this is effectively a toggle button which would ideally just be
interested in mouseClicked). For a variety of other reasons, I don't
want to make my code act on the mousePressed event.
Originally, our QA person asserted that it was busted because she was
clicking (and moving the mouse > 10 pixels) and it wasn't getting
"toggled" (this was on Windows). I won the battle there by saying
"don't move it 10 pixels; that's a drag, not a click". (after
debugging and figuring out that if you moved the mouse more than
approximately that much, the mouseClicked never came in).
However, she now claims that on Apple (OSX) that the button fails to
toggle if you move the mouse even one pixel while pressing the button.
(i.e. if you are not perfectly still while clicking).
Obviously this would be a different story. I don't have immediate
access to an Apple machine, so was wondering if anybody else had seen
this behavior. When I worked on the AWT on OS/2 at IBM, it was fairly
clear that the mouse events were determined based on native operating
system events (i.e. when Windows says it is a click, we'll say it is a
click). Don't know if that's true now or not, since I haven't seen the
code since Java 1.1.8.

//I like the fact that their are far fewer unnecessary symbolic names.
Yet I was hoping their was a one step command-line option to be sent,

//It's my understanding that -Wl,--add-stdcall-alias command-line

dlltool where the option should result in the @nn's being removed from
the table of symbolic names. Is this correct?

- load servlet mappings at runtime in tomcatCan anyone suggest a way to achieve dynamic servlet mappings in tomcat 5.5.
What I want to do is run a web app with any number of paths all pointing to
one servlet. These paths would be loaded from a database and extra paths
can be added at runtime by the user. So an example would be
www.domain.com/sample and www.domain.com/anothersample would both execute
the same servlet.
Another option I thought of was having a custom 404 servlet that would check
the request supplied and then redirect.

- using jsp:setProperty on non-simple types.Hi,
I'm currently having a small problem with my application. I'm using
some simple classes that wraps simple types to help me provide multiple
representation. For example, a DateCBO calls wraps the Date type and
gives me the oportunity to have various 'getters' like
getDateShortFormat(), getHtml(), getDateLongFormat() and so on.
My beans are using this kind of wrappers as their properties.
I have already made a custom tag to retrieve information that i use
instead of the standard jsp:getProperty
Now, i'm trying to use the jsp:setProperty to initialise the bean
property, but i have 'Could not coerce String to non-primitive type
StringCBO without bean property editor (JSP 1.2: 2.13.2.1) at line 13'
error.
Is there an interface that i can use to allow direct usage of
'jsp:setProperty', or should i create a custom tag as well.
thanks.

Symbian is by far the dominant mobile OS worldwide and don't see that
changing soon, although tons of linux phone shipments to china, which
has the largest mobile subscriber base in the world holds hope.
As always, Java ME is the application platform for all these devices.

- Eclipse 3.3 - external tool arguments issue.
I run the WebSphere command line wsadmin java tool as external tool in
Eclipse. It works fine except where an External tool argument has an
"=" sign as in "-javaoption -Dcom.ibm.ws.management.standalone2=xxxx".
Wsadmin picks up the "-Dcom.ibm.ws.management.standalone2" variable
but not the value. Seems that the Eclipse "arguments" dialog
truncates values after the "=" sign. Is there a way around this.
The arguments are listed below.
-user 1234 -password xyz
-lang jacl -host 11.11.11.11. -port 1111
-javaoption -Dcom.ibm.ws.management.standalone2=xxxx
-wsadmin_classpath C:\WASAdminSBV\WSAdmin\WAS5.1\JACL\proclib.jar
-f ${resource_loc}
The problem does not occur when Wsadmin is run from the command line.

- JDialog focusHi,
Is it possible to ensure that, upon setVisible(true), a JDialog pop-up
jumps on top of all other windows including other applications?
Many thanks in advance!

- Advanced Tooltips in JavaHi
I want to implement dynamic interactive tooltips in java so that the
user can expand / collapse them. Also, if there are hyperlinks in the
tooltip text, the user should be able to follow up this link. For the
same purpose, I need to be able to catch any events associated with
tooltips.
I tried to search a lot on how to customize the behavior of tooltips in
Java, however couldn't find any useful information. Does anyone know
about how to proceed about this? Any suggestions / pointers would be
greatly appreciated.
Thanks,
Shraddha
