I set classpath for jdom classes also included jdom jar/class files to jdk classpath but still it is not running.Pl help me and tell me where to set classpath for jdom?
Thanx

Hi all,
I am sorry that the reply I posted here was supposed to be send to http://forums.java.sun.com/thread.jsp?forum=31&thread=294049 - a million appologies!
Putting the required jar files within JRE installations (installed extensions) will require you to make these changes to all machines you are going to run your application - in some cases this might not be a feasible solution. Instead you can bundle the required jars along with your application (after verifying that its permissible to do so), and refer these jar files in the manifest of the executable jar file you are creating.
See http://java.sun.com/docs/books/tutorial/ext/index.html to know about extension mechanism and http://java.sun.com/docs/books/tutorial/jar/index.html to know about JAR files.
Launching an executable JAR file might not work on some platforms and also on the type of JRE installation you did. If everything else fails, try a JRE reinstall! :)
HTH,

Please I can not get a .jar file to run on XP SP3 start/run/cmd/

I can not get a .jar file to run on XP SP3 start/run/cmd/
Please help if can figure this out. I'm convinced it is a Windows XP SP3 problem from searching on google and seeing other ppl on XP SP3 with same problem (but no working solution for myself). I'll try to be complete-listing all I've done.
I had installed: Java SE Runtime Environment v6u14 for Windows Multi-language
I had checked here it was working properly: http://www.java.com/en/download/manual.jsp
I'm trying to run this jar file (soht-client-0.6.2.jar):
http://prdownloads.sourceforge.net/telnetoverhttp/soht-java-client-0.6.2.zip?download
http://www.ericdaugherty.com/dev/soht/javaclient.html < this is the information for the program.
(yes the file can be executed and should open the program's window
I wanted to post screenshot of it but friend that it's working for isn't here)
_(Please find log of all cmds I did in this post here: http://pastebin.com/f792983df )_
_I have extracted +'all' the files to: C:\062\+_ (I have tried using other directories, same problem)
++I then start/open/run/cmd+
then I: cd C:\062\+
then I try various commands - all+ of these do absolutely nothing- meaning no errors, no reply, no window opens, nothing except enters that directoy again:
java -jar soht-client-0.6.2.jar
java -jar -client soht-client-0.6.2.jar
java -client -jar soht-client-0.6.2.jar
java -jar soht-client-0.6.2.jar soht.properties
soht-client-0.6.2.jar
So I try this cmd: java soht-client-0.6.2.jar

SOHT Java Client
The SOHT Java Client requires a properties file. Either start
the application in the same directory as the soht.properties
file, or specify the file name on the command line:
java -jar soht-cleint-<version>.jar c:\soht.properties
So then I do these cmds which produce the exact same error/reply just above; Unable to load..:
j_ava -jar soht-client-0.6.2.jar -client soht.properties_
java -jar soht-client-0.6.2.jar -client C:\062\soht.properties
So then I copy soht.properties to C root and do:
java -jar soht-client-0.6.2.jar -client C:\soht.properties <same error as above
Then from other information I have read I right click on the .jar file, select open with Always open with:
_"C:\Program Files\Java\jre6\bin\javaw.exe"_
Try again.. same problem.
Then I do cmd:
_"C:\Program Files\Java\jre6\bin\javaw.exe" -jar "C:\062\soht-client-0.6.2.jar"_
does nothing, retry the other commands same thing (either nothing or those same replies)
Then I read (http://forums.sun.com/thread.jspa?threadID=5384879) someone had the same problem as I and they solved it by uninstalling all Java/reboot/ then install JDK 6 Update 14 with NetBeans 6.5.1 start NetBeans and then it worked for them.
So I unistalled all Java, rebooted and gave the cmd another try (before re-installing), now a new error, of course:
C:\062>java -jar soht-client-0.6.2.jar
'java' is not recognized as an internal or external command, operable program or batch file.
Then I install Java SE and NetBeans Cobundle (JDK 6u14 and NB 6.5.1) Final Release/ reboot/ open Netbeans/
go to test java page; all is good, run cmds again -and still nothing..
C:\062>java -version
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) Client VM (build 14.0-b16, mixed mode, sharing)
I reassociate program with: C:\Program Files\Java\jre1.6.007\bin\javaw.exe_
same thing.. nothing
Thank you very much for your time :D_
PS. My computer has been newly reformatted so needing another reformat I'm sure is not the solution.

Thank you very much for your replies Taggert_77 & swmtgoet_x :D
Taggert77_: I have never used NetBeans. I only installed it in the bundle as I had read on another post that somehow installing the bundle magically helped another user with the same problem (he didn't know why it worked after that either).
Before XP SP3 I was able to execute .jar file through cmd prompt. Now I am not.
This file is executable, grab it and you will see. Here is a screen shot (program in front is FlashFXP, behind is the cmd prompt and what should happen):http://www.freeimagehosting.net/uploads/53273b4ddf.jpg
swmtgoetx_: I only did the other cmd's to try to make it spit out something, anything lol :D
The proper cmd is simply: java -jar soht-client-0.6.2.jar
I did give your cmd a try, and it produced nothing :( (just like the other correct cmds)
java -client -jar soht-client-0.6.2.jar soht.properties
Thank you again...the mystery remains
PS. If you do a search for this you'll find an amazing amount of XP SP3 users with the same problem and no solution posted that I could find except one chap that did the unistall install order that I did above).

Imported Jar file not loaded at run time ORA-105100

Oracle 9iDS forms Version 9.0.2.9.0
Oracle 9iAS Release 2
I have imported java classes from a jar file into my form. I have it working in client server. Added the entries to the classpath in the default.env and system environment variable for development of the form and for execution.
Moved the jar file, form and testing html to the application server. Modified the classpath in the default.env file. Tested the form. Got the ORA-105100 error. MetaLink note 261650.1 states that error frm-40735 When-Button-Pressed triger raised exception ORA-105100 if calling a java function from a jar file. Cause: Jar file not loaded at run time. Solution: add in your default.env CLASSPATH parameter your jar file including the whole directory of the jar file location. That has been done and the OC4J has been restarted. Still get error.
Oracle support has not been able to give me much help as of yet. Does anyone have any further ideas, or documentation that I can read to help get this working?
Thanks in advance for any assistance that is offered.

Hey people any clues?

Using JAR file in running application and POI !

Hi all
I am trying to use POI HSSF f(for the first time, So pls bear with me!)or creating excel file from my java Application. I am using the jar file :
poi-2.0-RC2-20040102.jar. Not sure if its the correct one. So If I am wrong pls correct me.
Now I am creating a bat file to compile my application:
@echo off
C:\jdk1.3.1_04\bin\javac -classpath C:\POI\poi-2.0-RC2-20040102.jar MyApp.java
pauseIt compiles fine. Now If I try to use the jar file in run.bat for running my application, it says NoClassDef FoundError:MyApp. Here is my run.bat
java -classpath C:\POI\poi-2.0-RC2-20040102.jar MyApp
pauseI am not able to run my application with this run.bat file . If I change the content to:
"java MyApp.java"
It runs but give me error: NOClassDefFoundError:import org.apache.poi.hssf.usermodel.HSSFWorkbook
Pls suggest me about how to use jar file in running my app and how to rresolve workbook finding problem.
Reagrds

Try this:
java -classpath .;C:\POI\poi-2.0-RC2-20040102.jar MyApp
pauseNote the "dot semi-colon" at the start of the CLASSPATH. That puts the current directory in the CLASSPATH, which is where MyApp.class lives. (No package, right?)
See if that works better.

Migration from windows to Linux - JAR files not generating under JAVA_TOP

Hi DBA's
Jar files not generating under JAVA_TOP after migration from windows to linux.
I followed workaround but same in result.
Workaround
Run this command. It will give the missing file
adjava -mx512m -nojit oracle.apps.ad.jri.adjcopy -masterArchive $JAVA_TOP -sync -reportfile javatopfiles.lst
Then run this command
adjava -mx512m -nojit oracle.apps.ad.jri.adjcopy -masterArchive JAVA_TOP -sync -mode APPLY
I have checked in google.

How do I get a jar file to run directly?

I got it to work, as in the jar file runs fine from the command thing. However, I tried getting an html file to run it, but it just wasn't working.
This may be because I only had it incorporate the applet, and there ARE other classes, but I really don't know any html and I wouldn't know how to include those. Also, I don't know if it's an issue, but I don't think it's very plausible to have the applet both display things (my program has a GUI of sorts) and have the main method at the same time, given my program structure.
What can I do? Are there other ways besides creating an html document to run an applet? Is there a way I could include my other classes if that's the problem? I'd really like for it to be able to run in an internet browser- otherwise, my program probably won't reach as many people.

I got it to work, as in the jar file runs fine from
the command thing. However, I tried getting an html
file to run it, but it just wasn't working. To run a class with a main method you just use JRE. To run an applet you should use a browser with a Java plugin or the AppletViewer from JDK. For more info see this: http://java.sun.com/applets/jdk/1.4/index.html
This may be because I only had it incorporate the
applet, and there ARE other classes, but I really
don't know any html and I wouldn't know how to
include those. See the above link for some samples.
Also, I don't know if it's an issue,
but I don't think it's very plausible to have the
applet both display things (my program has a GUI of
sorts) and have the main method at the same time,
given my program structure.If your applet has a main method, the browser will just silently ignore it, so you don't have to worry.

Jar file not working - sometimes?

I have a jar file with the following Manifest file:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.5
Created-By: 1.6.0_02-b06 (Sun Microsystems Inc.)
Main-Class: windows.ItemCreatorUI
Class-Path: lib/AbsoluteLayout.jar
X-COMMENT: Main-Class will be added automatically by build
The class under the Main-Class header has a main method in it, and the jar file is executable on the six computers I have tested and had others test. However, two of my users have reported a "Can not find main method, the program will now exit" error and subsequent crash. They are using a copy of the file downloaded directly from my personal ftp, so I'm fairly certain that it's something on their end. Further, they have sent me the file that they downloaded and I was able to run it without fail.
Does anybody have any experience with this sort of problem, and know a fix? Both users have the most current version of Java (in fact, one of them updated to the latest version while I was working with him).
Thanks in advance

There is one more thing to test
I suppose it is a windows machine
open My computer>> from the title bar select
Tools>>Folder options
select "file types" tab
select JAR file
Click advanced
In the Actions column there will be an option open
slect open and Click edit
in the column Application used to perform Action
you have the below text
"C:\j2sdk1.4.2_04\bin\javaw.exe" -jar "%1" %*
*chang the javainstalation directory according to youe machine

Why is the .jar file not created??

the error i get is :
com.sun.kvem.midletsuite.InvalidJadException: Reason = 36
Error in opening jar file: list.jar
and in the \j2mewtk\2.5.2\apps\list\bin there are only 2 files are :
list.jad
MANIFEST.MF.
Why is that so?

Hi Sudipto,
I'm assuming that you used the <wsgen> Ant task (in your build.xml) to create this
web service, right?
Are you sure the client.jar file isn't in the web-services.war? You can verify this
by extracting this file (web-services.war) from the .ear for your web service, and
viewing its contents with WinZip (or the jar.exe utility that comes with the JDK).
There is a way to create client code without having a client.jar (or a WSDL document),
but it takes a little more work :-) I have attached a "heavily commented" example
of this, at the bottom of this post.

Hi,
I have developed a web service for our Internal network. I have deployed
the web
service onto weblogic 6.1 and have been able to obtain the wsdl file. I
have coded
my java client, but to compile and run the client, I require the client.jar
file,
which weblogic should create on its own once the actual web service is successfully
deployed. wl server is not able able to create the client.jar file and hence
I am
unable to run the client. Could anyone tell me why the client.jar file is
not being
created and is there any workaround for coding the java client without using
the
client.jar file.

Why are all jar files not compressed in the JRE installer?

I used 7zip to unpack jre-6u12-windows-i586-p.exe (Oracle JRE Installer). On unpacking, I got a core.zip, a zipper.exe and a few other files.
Again on exploding core.zip I found a few things. core.zip contains all the jar files just like it would be after installation except for 7 jar files.
charsets.jar
deploy.jar
javaws.jar
jsse.jar
localedata.jar
plugin.jar
rt.jar
Instead of these jar files there exists the corresponding packfiles
charsets.pack
deploy.pack
javaws.pack
jsse.pack
localedata.pack
plugin.pack
rt.pack
I think these are files created by pack200.exe & unpack200.exe is run on them after installation to create the corresponding jar files.
So now I have a few questions
Why are only these 7 files run through pack200.exe. I assume its because they are bigger than other files. But it wouldn't take that much effort to pack all jar files & unpack them after installation.
The .pack extension suggests that these are packed but not gzipped. Again why would Oracle not do a gzip also? for eg with rt.jar packing reduces size from 45 MB to 12 MB, while adding gzip also reduces it to 6 MB.

Whatever the truth of all this may be, you won't find it here. This is a user to user forum, not Oracle support or a channel to the developers. All you will get here at best is valid post hoc reasoning: at worst, guesswork. And if you're trying to bring this issue to Oracle's attention, again this isn't the place to do it. Locking the thread.

URGENT: New JAR file NOT being pushed to web clients.

Greetings...
When our web app first came to market, some of our customers were still using a dial-up connection. Therefore, since one of our web pages uses an applet, it was decided to ship the necessary JAR files to clients on an installation CD, rather than burden our dialup customer with having the JAR files pushed out to them over the line. The jar files are installed in the C:\Program Files\JavaSoft\JRE\1.3\lib\ext directory on the client computers.
Don't ask why, but we are now attempting to have our web site push out a new JAR file to just one of our clients, but the problem I'm running into is that if the OLD jar file already exists in the C:\Program Files\JavaSoft\JRE\1.3\lib\ext directory, the NEW jar file isn't pushed out by the website. My understanding was that the system would automatically detect if the JAR file on the client was older than the JAR file on the server and would then push the newer JAR file out to the client, but obviously, I'm missing something.
Any help/suggestions you can provide would be greatly appreciated. Following is the kludgy ASP code for this...

I guess the problem is, that your local jar file's classes copied to the JRE's ext directory have higher priority. The JRE does not store your applet jar locally and so does not overwrite anything you may have installed, it only executes the jar file given by the browser which may cache it or not.
Why don't you use the Java Webstart technolgy? It's pretty simple to use it. Customers would have to download every new jar version only once and Webstart will take care that the local version is up-to-date every time your app is started.

Help with creating jar file and running it ?

Hey guys,
I have a program with a package called classes and a sub-package called classes.mainLib.
I am trying to create a JAR file of the class files in mainLib. There is only one class file in classes and that contains the main method. So this is what i am doing:
1. create a manifest file with: Main-Class: classes.Cars
2. from within the mainLib directory (./program_name/classes/mainLib/) i do this:
jar cvf mainLib.jar manifest ./*.class
3. Then i move this jar file to ./program_name/lib and change directory to ./program name/
4. try to do this: java -jar ./lib/mainLib.jar
But it errors with:
gary@linuxbox:~/java/cars$ java -jar ./lib/mainLib.jar
Failed to load Main-Class manifest attribute from
./lib/mainLib.jar
Any ideas why this is happening. the manifest is included in the jar'ing
Thanks.

At a glance, it looks like you are placing only the
class files in the jar and trying to navigate your
classpath to run it. Instead, you have to place ALL
the package folders into the jar from the root of
your package hierarchy and the jar runs anywhere, in
any folder. The packages are INSIDE the jar.
also I see cars/classes in a path you describe ...and
the program seems to wnat classes/Cars ??? Could
this be an additional issue (or am I missing seeing
something about your package structure)?Firstly, i believe all my spelling and cases are correct.
I have the following strcuture:
Cars.class (contains main) : package classes in ./classes directory
All other classes : package classes.mainLib in ./classes/mainLib
I would like to jar ALL files in mainLib but not the class that contains the main method. Is this possible?
I'm not sure how clear i was earlier, hope this is more understandable.
