- An enum mystery solvedI was baffled why the compiler would not let enum constructors access
the enum's static variables.
I consider it a bug, but an understandable bug.
I think the reason is the enum invokes the constructors for the enum
constants in static init code. Somebody was worried that the static
initialisation would not be complete. Yet it is quite safe since the
enum constants are the last bit of static init.

- print pdfs from java java programI seen a handful of libraries that can produce pdfs. I'm looking for a way
to print them and possibly print preview them from a java application. Does
anybody know of a tool that can do that? I'm using iText (if it makes any
difference).
Hmm... just as I was writing this, I saw a mention of another library,
jpedal (jpedal.org) and it says it can "view" them. I'm going to try it out
tonight but I doubt it will do printing.

- CLASSPATH help using classes and jar files.I am new to java, what is the correct way to define CLASSPATH for the
files like test.class or test.jar. In unix if I want to provide a
PATH to an executable like /userfiles/test.exe I would do the
following:
PATH=/userfiles
This provides a directory to search for.
In JAVA, I thought it was the same, but in some instances on our system
I see it point to the exact class file. For example:
CLASSPATH=/userfiles/test.class
Shouldn't it be CLASSPATH=/userfiles ?
The same for JAR files. Should it be CLASSPATH=/userfiles, or
CLASSPATH=/userfiles/test.jar
Thanks.

Neither one works. The environment variable is 'CLASSPATH', not 'classpath',
and you don't put spaces in it.
Even after correcting those errors, the second form will not pick up the JAR
files, nor is the first form isn't necessary because the JARs in the
$JAVA_HOME/lib/ directory don't need to be part of the classpath explicitly.
In any event, all your questions should be answered by the information in the
documentation:
<http://java.sun.com/javase/6/docs/technotes/tools/windows/classpath.html>
I strongly recommend that you do not use the CLASSPATH envar, but use the
-classpath (or -cp) option to your Java tools. CLASSPATH is far too global.
Also, read
<http://java.sun.com/javase/6/docs/technotes/tools/findingclasses.html>

- Java algorithm (diff) question.I have two CSV files (file1 and file2).
Each file contains 50,000 + lines. Each line is very long.
The first entry in each line is a key as shown in the example below.
Example:
key1,val1,val2,val3....
key2,val1,val2,val3.....
etc
I would like to do a "diff"(unix like) between file1 and file2 and
find out
the lines that are different. The entries in each file are not
necessarily sorted by key.
Approaches I considered.
1. To load all the entries into a hashmap using the key's as a key and
the rest of the line as a value. This is a problem because of memory.
2. To generate the hashcode for each line and use the key and the
hashcode to
store in a hash map and do the comparison. The problem here is that
two different strings could have the same hashcode (false positive).
Any suggestions would be appreciated.

- Flush ResultSet to BrowserHi. I am querying an Oracle 9i database that in some cases will return
very large resultSets (up to 95,000 rows). I am using Java Server
Faces for my front end but I am having some major performance issues,
for obvious reasons. My question is this: Can I start flushing the
database results to the textarea in the browser before the query
completes to give the illusion of speed? Here's the current slowly
working code. Thanks in advance for your help.

- Subclassing a text area..I would like to create a component that is based on the TextArea, but I'm
not really sure where to start. Basically this component would behave the
same as a text area, but would highlight certain portions of the entered
text as it is entered e.g. incorrectly spelled words.
I would like to package this as a separate component that I can add to
other projects I'm working on.
Is there a good text that would provide examples on how to do this sort of
thing?
Thanks.

- Handling multiple attributes with w3c ElementQuestion from a new java programmer (I inherited this project when our
dedicated java guy left)...
It seems in his XML documents, there is usually only on attribute for
each element..
i.e. <ClubMember officer="T">
and to generate this I use:
Element retVal = DomUtiliy.addElement(parent,
"ClubMember").setAttribute("officer", "T");
In new new case, I'd like to create something like:
<ClubMember officer="T" elite="T" current="F">
and I can't find a method in the org.w3c.dom.* namespace to do such a
thing as .addAttribute to an Element. It seems you can
only .setAttribute. Is there an wasy way to add mutiple elements? An
example out there somewhere?

- JavaMail is not working on FreeBSD 6 (amd64) using linux-sun-jdk14I'm trying to port an application currently running FreeBSD 5.3 (i386)
using jdk14 to FreeBSD 6 (amd64).
First I tried jdk14, with this result:
hallandsen# make -V IGNORE minimal=YES
"is only for i386," "and you are running amd64"
Then I tried linux-sun-jdk14.
It installed successfully, but there seems to be a problem
sending emails with JavaMail.
1 System.out.println("## New MimeMessage");
2 Message msg = new MimeMessage(session);
3 System.out.println("## New MimeMessage passed");
It never reaches line 3, no sign on what's wrong.
Has anyone of you an idea of what to try or am I out of luck ?
Thanks,

java-programmer, Java and X509 Certificates .. help!!
Hello,
I need some help! I would like to know if it is possible to get, from
the browser (web client), the server X509 certificate used by it in an
already SSL established session with the client (browser). As in the
server side, with your application you can get the client X509
certificate used by the client in order to authenticate himself, it
should be an analogous process or API in the web client to get the
server certificate.
The aim is to develop some client script (preferable JavaScript, but
could be with Java Applet) in order to deal with the server X509
certificate fields.
Can you help me? Thanks in advance!!
Best regards,

java-programmer >> Java and X509 Certificates .. help!!
Could n't you get the SSLSession from the SSLSocket using getSession and
then use getPeerCertificate or getPeerCertificatChain to get the
certificates?
something like this..
.....
SSLSession session = socket.getSession();
java.security.cert.Certificate certs[] =
session.getPeerCertificates();
for (int i=0; i < certs.length; i++) {
System.out.println("Certificate[" + i + "]" + certs[i]);
}
javax.security.cert.X509Certificate X509certs[] =
session.getPeerCertificateChain();
for (int i=0; i < certs.length; i++) {
System.out.println("X509 Certificate[" + i + "]" + X509certs[i]);
}
.....

- JMenusHello everyone! I was hoping I could get a few pointers on the code below.
Basically the program is using JMenus. When the program first runs the only
menu that is there is Session wherein users may login to the system. There
is a tab for an existing user and a new user. The new user is working
alright. However, existing user is not. I am not quite sure how to get
around that one. I have to check the ArrayList Users to find out if the
password entered matches one in there or not, if it does then they enter the
system, if not is asks them to enter the correct password. I have that in a
for loop right now, but that is not working, does anyone have any ideas for
me? This part of the code is in passwordfield.addActionListener and signin.
addActionListener. Next after a user enters the system 3 more menus are
available...Read File, Sales Data Entry, and Write File. Read File has two
tabs - Text File and Object File. Text File just reads a text file and puts
in the Salesman ArrayList and Object File reads in objects and prints them to
the text area. Write File has two tabs - Write Text File and Write Object
File. Write Text File writes the Salesman Array List to a text file and
prints it to the text area and Write Object File writes a text file as
objects to another file. Then Sales Data Entry has two tabs - Update Current
Salesman and Enter New Salesman. I actually haven't put the calculations in
the code yet, but they will basically add the salesman data to the Salesman
ArrayList.
So the problems I seem to having other than the password part above are:
(1) with currencyFormat.format(total) in writetextFile() and readobjectFile()
it is not allowing it to put it in currency format and I don't really
understand that. I have import java.text.NumberFormat; in SalesMenu(). Does
anyone have any idea of why this might be happening?
(2) output (the textarea) is not being read in the writetextFile() and
readobjectFile()...i am sure this is something simple I am just not realizing.
Does anyone know why it's not allowing me to print to the output?
I realize this is a long piece of code, but if anyone has the time to help me
out I would greatly appreciate it. I didn't know how much of the code to
post, so I just decided to post the whole thing. Again, I haven't done the
calculations yet, but I am going to work on those right now. Thank you for
any tips you may be able to give! I appreciate it!

- Drag and drop an URLHello,
can you give an advice please? I learned how to drag and drop an URL from my
web browser to my Java application. But it does not work as I would like.
For example if I drop URL http://java.sun.com/ my application receives
http://java.sun.com/Java Technology where "Java Technology" is not the part
of URL but page title. Is there any way how to receive pure URL without the
page title? I worry that by cutting off everything after the last slash I
can damage some URLs. I use DataFlavor.stringFlavor.
Thank you! Vojta

- JGSS Kerberos issuesI'm trying to implement single sign-on using jCIFS. I'm having
difficulties with Kerberos on some clients. For some reason, the web
browser on my machine defaults to NTLM authentication, and that's
working fine. The problem I'm having is when a client tries to use
Kerberos to authenticate. I've tried setting jCIFS flags to turn off
Kerberos, to no avail. I've read the documentation and configured
Kerberos accordingly. I just can't get past this error. Relevant info
below:
Environment:

- ant-regexpI would like to use the following regexp:
<replaceregexp flags="g" match="\n\[\s&&[^\n]]+" replace="\\\\n">
<fileset dir="/home/public/dbs/regexp"
includes="applicationLogMessages.properties"/>
</replaceregexp>
unfortunately, eclipse marks this as an error as soon as i type a "&".
my goal is to replace all NEWLINEs where the new line starts with a
WHITESPACE with a \n, but keep it on the same line.
if the next line is empty(simply a NEWLINE) i want to do nothing!
how can i achieve this (without using &)?
thankful for all hints.

- selective page accessI just need a, "it can be done" answer. I want to build a web
application, which will allow users to access pages, based on four
different user attributes, namely, "department", "trading partner
type", "designation", and "customer". I want to allow declarative
access, meaning I want even lay administrators to edit a configuration
text file so that a new or old user's profile can be changed. Can this
be done just with Tomcat and Struts, or do I need to used EJBs?
Thanks,

- Problem wih the progressbar in statusbar with frames in IEHi, i've an anoying problem.
SITUATION
I created a webpage with CSP (crystal Enterprise ASP pages) and
Javascript. The page consists of frames. When someone pushes a button
in one frame (grouping of cubes and reports) i load another frame with
report and cube links. When someone pushes a report or a Cube link an
ActiveX or a DHTML viewer is started.
THE PROBLEM
The problem is that when someone pushes a button in the GroupFrame the
reports and cube links are loaded correctly, but the progressbar below
in the statusbar keeps running. It's showing that not everything is
loaded yet, but everything is loaded!!!
The next time when i push a button in the group frame all the links
are corerectly loaded but now there's is no progressbar (so correct)
and then the next time when i push the link in the groupframe again
Again a progressbar is continously shown (what the heck??!!)
It has something to do with frames because when i load the information
in a pop up screen it doesn't show a progressing progress bar.
I hope that someone can help me with this problem..
Thx

- About Reflection (or not)Hello everyone..
Here I am again for another question.. :P
Suppose we have the following class
public class Test {
private Test2 test2 = new Test2();
public void testMethod() {
test2.test2Method();
}
}
Is there a way, using anything (probably reflection) to know that the
method testMethod of this class calls test2Method() method of Test2
class..? Or the other way around.. Is there a way to know what classes
call Test2's method test2Method()..?
Any help/reference/book etc. is appreciated.
Thank you very much.

- Setting column titles in JTable, TableDialogEditDemo exampleHello,
This is no doubt a really dumb question, but I don't see where in the
example TableDialogEditDemo.java (from Sun's Java examples) that we "tell"
the table to have one fixed row, to make it grey, and to use getColumnName()
for the column headers? (Stated another way, what would I do differently if
I didn't want the column titles to be grey, for instance?) The full java
listing is below.
Thanks,

- Broken behavior of java.io.File()I'm seeing several examples of broken behavior with java.io.File():
* mkdirs() sometimes returns false, despite succeeding (the directories
exist afterward on the
filesystem)
* exists() and isDirectory() sometimes return false when called on a
File object right after a
mkdirs() after which the directory and its parents existed, as
observed using Winblows
Exploder.
What is going on here? Is there even a way to test for the existence of
a directory with 100% accuracy?

- MySQL Select help neededHi All,
Trying to work out the correct sql statement
If I have a table that contains the column partpostcode and has these
entries,
PE10
PE15
PE1
What I want to do is select those rows where the partpostcode exists in
a given parameter,...
i.e something liek.
Select * where partpostcode IS CONTAINED IN "PE10 1AF"
sadly there are no IS CONTAINED IN keywords, but i'm not sure how to do
it using LIKE or IN...
Any comments ?
Thanks,

- Classes in jar can't load - why?I've just created a jar-file containing some classes that I've made. I have
made this jar file in Idea IntelliJ's AntBuild. However, when I try to use
the jar file in a project I get the following message:
cannot access Teleadress.DMP2004.DTDClasses.CompanyResult
bad class file
D:\IdeaProjects\DTDFileTest\lib\DMP2004_DTDClasses.jar(Teleadress/DMP2004/DT
DClasses/CompanyResult.class)
class file contains wrong Class: CompanyResult
Please remove or make sure it appears in the correct subdirectory of the
classpath
The thing is that it works perfectly when I open the jar-file with WinZip
and copy all the class-files to the classes folder in my project. Moreover
when I write Teleadress.DMP2004.DTDClasses. the autocomplete function shows
a list of all my classes including CompanyResult. However, as soon as I
chose CompanyResult it turns red meaning it can't be found. This is also the
case with all the other classes in my jar.
Why is this? I've checked other jars and the only thing that is different is
the manifest-file which in my case is more or less empty.
