- ParseException Error. Please Help!!Hello all!
Very new to Java need to complete this assignment for a school
project. The code below creates a few books (Title, Author or Authors,
Publisher, Number of pages, Publication Date etc.)
Methods have been developed to display a book's information and to
compare two books by title, number of pages and, HERE IS THE PROBLEM,
publication date.
Date has to be in the "dd-MM-yyyy" format.
The code works alright if we leave out the compPubDate method (line
55) and the calling of that method at line 95.
The message I get from the compiler is this:
Library.java:95: unreported exception java.text.ParseException; must
be caught or declared to be thrown
book2.compPubDate(book4);
There must be something wrong with my method that I don't understand.
Could anyone please help me fix this for me? Any help would be greatly
appreciated!

- Struts and mapped propertyHi
I'm using Struts with DynaActionForm wich as 3 to 8 Map as property, so I'm
using mapped property.
When I put them into HTML form it result in INPUT fields having names like
'map1(property1)' this leads to problems in writing Javascript.
Can I use another format in mapped property names?!
thanx

- JDBC to MS AccessHello,
I have just wanted to use such line to add one field into ms access
database:
st.executeUpdate("INSERT INTO DateTable (Date) VALUES (#2006-09-06#)");
Table DateTable has two fields: DateID (autoincrement) & Date
(date/time type). Compiling it I got an error:
"[Microsoft][ODBC Microsoft Access Driver] Syntax error in INSERT INTO
statement."
So it seems that my insert is not well formulated. Ok, but when I copy
it to MS Access I have no problems with running it (i.e. I get no
errors and a new row is added). Could you tell me what is going on?!?
Regards, mark

- JAXB 2.0 Question?Hi,
I have created Java classes from an XSD using IntelliJ 6 and JAXB 2.0
plugin. I have populated the object and when I try to marshal the
object, I am getting ns2 appended to my root (default) element. I have
added a XmlRootElement tag to my root element. For the sake of
simplicity, I tried to unmarshal an XML file and then marshal it again
(without doing anything in between) as seen next:
My original XML file looks like the following:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><MSG
xmlns="http://xxx.yyy.com/"><ACKNOWLEDGEMENT>Success</
ACKNOWLEDGEMENT></MSG>
When I unmarshal it and marshal it again (doing nothing in between), I
get:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><MSG
xmlns:ns2="http://xxx.yyy.com/"><ns2:ACKNOWLEDGEMENT>Success</
ns2:ACKNOWLEDGEMENT></MSG>
I have used the same techniques before and they worked successfully. I
do not think the problem is with the XSD. Could you please tell me why
am I getting ns2 appended to my root element? and how can I get rid of
it?
Thanks in advance

it doesn't sound like it should be too difficult.

- Swing design, components vs. containersHi,
Can anyone explain me (or guess on) the motivation for why the Swing
developers decided to let JComponent extend the AWT Container class and
not the AWT Component class?
I find it strange that Swing does not seperate containers from
components in the class hierarchy (ie. you can add buttons to buttons etc.).
Any comments on this issue would be appreciated.

- Sockets with unsigned appletsHi,
I'm working on a small java game applet that will need to connect to a
gameserver. The game server is different from the web server hosting
the applet.
From what I've read then the only way of doing this is by getting a
certificate and signing the applet - is this correct?
Or is there anyway to do this without a certificate?
Thanks,

- Dynamic Network Printer Discovery and Administration via jcifs.samba.org.I am working on a large-scale reporting solution. One component is to
be able to scan the network for all printers and maintain a record of
these printers. I have read many, many posts on these forums with
similar questions, most of which do not have any answers. Below is the
progress I have made so far, hopefully someone can offer some
input/insight.
1. Finding Network Printers - I used jcifs to browse the network and
find all shared devices that were printers.
Code:
private static void findAllPrinters() throws Exception {
SmbFile root = new SmbFile("smb://domain;USR:PASS@domain");
Hashtable printerHash = new Hashtable();
searchForPrinters(root, printerHash);
Enumeration keys = printerHash.keys();
System.out.println("Number of Printers Found: " +
printerHash.size());
SmbFile file = null;
while (keys.hasMoreElements()) {
file = ((SmbFile)keys.nextElement());
System.out.println("UNC: " + file.getUncPath());
}
}
private static void searchForPrinters(SmbFile root, Hashtable
printers) throws Exception {
SmbFile[] kids= null;
try {
kids = root.listFiles();
} catch (Exception e) {
}
if (kids == null)
return;
for (int i = 0; i < kids.length; i++) {
if (kids[i].getType() == SmbFile.TYPE_WORKGROUP ||
kids[i].getType() == SmbFile.TYPE_SERVER)
searchForPrinters(kids[i], printers);
else if (kids[i].getType() == SmbFile.TYPE_PRINTER) {
printers.put(kids[i], Boolean.TRUE);
}
}
}
By doing this I can find each printer on my network that I can find
when I use windows control panel and search for network printers.
2. I can print a test to any printer successfully.
Code:
FileOutputStream fos = new
FileOutputStream("\\\\PrintShare\\MyPrinter"); //hardcoded for test,
but taken from output of part #1 above.
PrintStream ps = new PrintStream(fos);
ps.print("\r");
ps.print("This page will be printed directly to the printer.");
ps.print("\f");
ps.close();
3. This is where i need help. Continuing on what I have already
accomplished...
A. How can I create a more complex printer reference to allow me to
control number of copies, color vs. bw, page layout, page size, obtain
details from printer such as acceptable page sizes, data types
printable, etc.
B Be able to detect printer errors and if the page has completed.
And and all input and/or collaboration is apprecaited! I feel I am
close to finding the link, but not sure where to find the missing
puzzle piece.
Thx,
Rob

java-programmer, Terminate a process tree
Hi group,
I'm new here, so apologies if I ask this in the wrong way.
I have been programming in java for about 2 months, and am currently trying
to control an external application that I start using:
Process proc;
Runtime rt;
proc = rt.exec("java.exe -cp ... etc.. something");
Then I capture the input/output & error streams and thread them off.
The problem I have, is that I need to architect for the eventuality of the
external process locking up and not responding to requests. I have the
whole capturing of streams in a timeout, so I can tell when the external
program has not responded within a reasonable time, however when I issue the
proc.destroy() method, the java.exe process takes up almost 100% cpu and
never stops. I have to use operating system tools to perform a manual kill
of the process.
I can only assume that the proc.destroy() doesnt kill the entire process
tree, and because the command line starts off java.exe, which runs the
something.class file, a process is orphaned somewhere.
Any help would be much appreciated.
Thanks
Wayne

- Need to create custom taglib similar to bean:messageFirst off let me just say that while I know "java" pretty well from
about 3-4 years ago, but I am not really up to speed on all the JSP and
Struts things going on but I'm learning as fast as possible :-)
That being said, I have been thrown feet first into a new project and
have been asked to do this.
So anyway I am using resource.properties files to store all of our
strings and I have been adding them to our JSP's using the bean:message
taglib.
This works great and I have no problem creating different property
files for multiple languages using localization.
My problem is that the app we are writing is for one company that
operates in different states (OH, IN, etc...) The business logic for
each company is very similar but sometimes the language needs to change
between states. Further confusing the issue is that this one company
has sub companies which operate in multiple states and each company is
very similar. So I have come up with the idea that I would like to use
the "key" element of bean:message to try to create a sort of
localization scheme for the companies and states.
Here is is my idea. I would like to create a taglib that works exactly
like the bean:message taglib except that you pass in key names that are
like "promptname.company.state". The taglib will look for a key named
"promptname.company.state" and if it exists it will return it, if not
it looks for generic key for that company "promptname.company" if that
does not exist it looks for "promptname". If that key does not exist
it returns error or ???key?? as normal.
The idea is that we create a generic base for the application and
customize the prompts from the differences. Seems like a good idea to
me, heck, there may even already be a taglib out there that does this?
My problem is that I don't know where to start with extending the
bean:message tag. Theoretically it wouldn't be a problem to just keep
sending requests and stripping off .company and .state until you found
one.
Can someone point me in the right direction for doing this? This would
really save me some time.

concern.
I have a distibuted java application (is this the right term?) that exists
on many users PCs on a network. This is essentially just gui code. I then
have a central java 'server' application that applies the model & all the
business rules.
The view application needs to deal just with the business app, which in turn
deals with the data layer, MySQL, Flatfile or whatever. I think this is
pretty standard practice?
My basic understanding so far is that I should define the interface by which
the protocol operates. I'm not entirely sure how to do this and what else I
need to do, though I imagine proper threading will form a crucial aspect of
this.
Can anyone recommend a good book that assumes half decent OO & java skills,
and that I can apply to the developer certification. I've got the Sybex
book 'complete java2 certification' but it glosses over a great deal of
networking.
Does anyone know of anything online that would help me?
Perhaps people could profer a Joshua Bloch style list of networking does and
don'ts?
TIA

Hi,
I am having a problem building jdk1.4.2p5. I already have jdk-1.3.1p7_2
installed from my installation of OpenOffice1.03
Do I have to first remove jdk1.3.1 before I install jdk1.4.2 ?
I am in the process of upgrading OO1.03 to 1.1, attached is my error
message.
Any help would be appreciated.
Thanks,
Nelis

- Program can't count argumentsHi,
I have written a .java file with below source code.
public class getargs {
public static void main (String [] args) {
System.out.println(args.length);
}
}
Compilation succeeded. But when I ran the program with below
parameters:
java getargs abc
or
java getargs "abc"
the program returned 0 in both cases. If I don't intertpret wrongly,
args.length should contain the count of program arguments. Why would I
get the result as I ran this program ?
I run java SDK 1.4.1.

- Bug#388596: gcj-4.1: CharsetEncoder.canEncode() gives different results than Sun versionPackage: gcj-4.1
Version: 4.1.1-13
Severity: normal
The following test program gives different results with gcj and Sun JDK:
// A.java
import java.nio.charset.Charset;
import java.nio.charset.CharsetEncoder;
public class A {
public static void main(String[] args) throws java.io.IOException
{
CharsetEncoder enc = Charset.forName("US-ASCII").newEncoder();
System.out.println(enc.canEncode('\u00e4'));
}
}
// end
$ javac A.java
$ /usr/lib/jvm/java-1.5.0-sun/bin/java A
false
$ /usr/lib/jvm/java-gcj/bin/java A
true
The Sun version seems to return something like (c > 31 && c < 127),
which makes sense, whereas gcj always gives true.
This breaks lots of code, such as Apache JaxMe 2 version 0.51
(specifically the MarshallerTest in the test suite, which generated
invalid XML with gcj).

- implement writeObject how? serializable singleton how?I have code that I want to execute only once ever, as a side-effect of
constructing an object. I have put this in a static initializer. But,
if I want to allow the object to be serialized I seem to be stuck,
since the initializer is executed during deserialization.
In the java developer's almanac:
http://www.exampledepot.com/egs/java.io/DeserSingle.html
There's an example of a serializable singleton:
public class MySingleton implements Serializable {
static MySingleton singleton = new MySingleton();
private MySingleton() {
}
// This method is called immediately after an object of this
// class is deserialized.
// This method returns the singleton instance.
protected Object readResolve() {
return singleton;
}
}
If I add code to the constructor, it executes during
deserialization, so that doesn't work for me.
Is there someway to determine within a static initializer or
constructor that this object is being constructed and not being
deserialized? If there were I could execute code only during the one
construction of the object, and not again.
I was thinking that I could implement readObject/writeObject. But, how can
I implement writeObject? How do you represent the fields?
In the oreilly RMI book there is an example of a writeObject method,
but it doesn't explain how you are supposed to represent fields of the
object. I've looked around a bit and found nothing.

- Java Threads - Get running threadsHy there,
I'm building an application that creates a thread. This thread creates
other threads to perform several tasks.
My question is simple. Being this main thread created in a JSP page,
and still running after the user logs out, how can i get the current
status of the thread? I would like for the user, when he logs on the
application, to verify if the thread is active, that is, the current
status.
I can't seem to be able to get the thread once it is initialized.
Thanks in advance for any help.
