Environment embed jar file

Hi there,
Is it possible to package the database in a jar fille and create an enviroment using this embedded database?
The following code-snippet does not work:
URL url = PcTools.class.getResource("/00000000.jdb");
File envdir = new File(url.getPath().substring(0, dirName.lastIndexOf("/")));
myEnv = new Environment(envdir, envConfig);
thank you in advance

Problems with signed JAR files in JWS/JRE6 environment.

Hello All,
I'm encountering a problem running our desktop application as a Java Web Start deployment in a JRE 6 environment. There were never any problems when running the same application as a JWS deployment in JRE 1.4, or 5, environments. There are also currently no problems in a JRE 6 environment when running the application as a standard desktop application.
The problem which I am having has nothing to do with launching the application. But for good measure, I verified the JNLP file with JaNeLA. A couple things we out of order, which I addressed to make JaNeLA happy, but my problem still persists. Here is my JNLP file (anonymized to protect the innocent):

When running as a JWS deployment, on JRE 6, the application will be functioning normally for a little while, and then suddenly the following exception is thrown, and the current operation fails because the class in question cannot be accessed:

The classes of our desktop product are contained within the 'acmedesktop' and 'acmeapi' packages. It requires access to the hard drive of the workstation, and therefore, all jar files included with the application are signed using the following ANT task when compiled:
<signjar keystore="resources/codesigning/keystore.pfx" storetype="pkcs12" storepass="myPassword" alias="myAlias">
     <fileset dir="${jws_dist}/app" includes="*.jar"/>
     <fileset dir="${jws_dist}/app/lib" includes="*.jar" excludes="jhall__V${dt_version}.jar"/>
</signjar>-----
Therefore, all classes, within all jar files, are signed with the same certificate (with the exception of the JavaHelp libraries, which are already signed by Sun - but the class in question attempting to be loaded here is not contained within the JavaHelp jar file anyway). So, the point being, that the exception message stating that the "signer information of the acmeapi.communication.CDocImpl class doesn't match the signer information of other classes in the same package", is simply not correct. All classes within that jar file were signed using the same certificate.
I downloaded the JRE 6 source from dev.java.net and picked through this issue with a debugger. The ClassLoader.checkCerts() method compares the certificate used to sign the current class which is attempting to be loaded, with the certificates which signed all other previously loaded classes within the same package. If they don't match, the exception above is thrown. What is causing the issue is when the checkCerts() method attempts to get the certificates which signed the currently loading class, null is returned. And obviously, comparing null, with an array of the certificates which signed the previously loaded classes, isn't going to match; therefore this exception is thrown.
The checkCerts() method gets the certificates of the currently loading class by calling the java.security.CodeSource.getCertificates() method. Tracing deeper in the debugger, the CodeSource object ultimately gets the certificates from the 'signersRef' member variable of the com.sun.deploy.cache.CachedJarFile class. signerRef is a SoftReference object and can therefore be garbage collected at some point. If it has already been garbage collected, the CachedJarFile class will attempt to retrieve it again from the loaded cache entry by calling com.sun.deploy.cache.MemoryCache.getLoadedResource().
The MemoryCache class maintains the cache entries to the jar files as MemoryCache.CachedResourceReference objects, which subclass WeakReference, and therefore these objects can be garbage collected as well. If the cache entries have also been garbage collected, this leaves the CachedJarFile class with no ability to repopulate the CachedJarFile.signerRef object. Therefore it is completely out of luck getting the certificates which signed the currently loading class, which ultimately causes the above exception.
When the com.sun.deploy.cache.Cache class attempts to retrieve a cache entry using its getCacheEntry() method, it will attempt to get the entry from the MemoryCache class, if null is returned, it will recreate the cache entry and add it back to the MemoryCache. In contrast, when the CachedJarFile class attempts to get a cache entry from the MemoryCache class, if null is returned, it just gives up.
(from com.sun.deploy.cache.CachedJarFile:244)
private CacheEntry getCacheEntry() {
     /* if it was not created by Cache do not search for entry */
     if (resourceURL == null)
          return null;
     CacheEntry ce = (CacheEntry) MemoryCache.getLoadedResource(resourceURL);
     if (ce == null) {
          //This should not happen because CacheEntry should not get collected
          // before CachedJarFile is collected.
          Trace.println("Missing CacheEntry for " + resourceURL + "\n" + ce,
               TraceLevel.CACHE);
     return ce;
When debugging, code execution falls within the code block with the comment stating "This should not happen...", but it is happening in my case.
On an interesting side note, using the jvisualvm.exe tool included with JDK 6, I was able to tell that it seems as though these objects are collected the first time that the JVM allocates more heap space, and then the issue will occur. If I set the initial heap size very large (using -Xms) this issue won't occur at all. But that is kind of a bad solution which I would rather not do, but it is interesting to note for the sake of troubleshooting this issue. The max heap size (-Xmx) is plenty big enough, so the issue is not that we are running out of memory here.
Does anyone have any insight as to what could be causing this? I've searched, and found a couple threads with similar problems but with no clear solutions. It is not just one workstation either, it happens everywhere I deploy the app as a Java Web Start application in a JRE 6 environment. I have been using version 1.6.0_18 on XP, but it seems to happen on any update version of 1.6. Is the fact that the CachedJarFile class doesn't attempt to reload the resource when it can't retrieve it from MemoryCache a bug? I've dug as deep as I can on this and I'm at wits end, does anybody have any ideas?
Thank you
Jake

I think you should raise a bug report and seek Oracle's response.

Is it possible to call a class in a jar file from JNI environment?

Hi
Is it possible to call a class in a jar file from JNI environment?
Thanks in advance.

Could you explain a bit more what you are trying to do? (In other words, your question is vague.)
o If your main program is written in C, you can use JNI to start a JVM, load classes from the jar of your choice, and call constructors and methods of the objects defined in the jar.
o If your main program is java, and has been laoded from a jar, a JNI routine can call back into java to use the constructors and methods of classes defined in the jar(s).

ODI - Multi development environment how to share the JAR files

Hi,
For some of our functionality, existing KM not sufficient so we created with our own KM and we have called some jave code which we created and place inside lib directory of ODI as a JAR file. there are four people in the development work. so we have four development environment(all are complete installation, i.e while installing we choosing Complete Option).
One of our developer created the our own KM and he placed the jar file in his own Dev environment's lib Directory. Since four Dev environment shares the some work rep we could see the new KM and all the ODI object in all the dev env. but if we run the the ODI interface which use the new KM from other Dev environment where we dint place the jar we are getting Error.
if we keep the jar file in all the other three Dev environment's LIB directory then respective interface working.
here my doubt, is there any other way to share the JAR file to all the Environment without copying into everywhere?
Thanks
Knidhi

Thanks you verymuch Cezar and Ratish, now almost i got the answer for my question.
i installed ODI Server into separate machine. it has folder structure as follows
Directory: D:/ODIServer/oracledi/ has the following subfolder
1.bin 2.drivers 3.lib 4.tools.
here i need to keep my Jar files under the lib folder. am i right?
and bin directory contains only Agent related batch files. (agent.bat, agentscheduler.bat,agentservice.bat,agentstop.bat,agentstart.bat,agentweb.bat and jython.bat and respective .sh files)
here dont know how to precede the following things
1. how to configure the Master and Work Repository information with ODI Server?(MR and WR i already created with the help of one the ODI Client)
2. how to configure the Client machine to Server?
3. Since ODI Server not having the Topology, how to create the Agent? do i need to use any one of the ODI Client for this task?
--Thanks

Question about using third party jar files in Java Web Start Environment

Hi everybody, I got a very strange problem and still can't figer out how to solve it. Can anyone help to overcome this problem?? Thanks in advance.
Question: I wrote a simple java swing application to connect to Oracle database. I packed whole my classes and a third party jar file(classes12.jar) to a new jar file named "IRMASSvrMgntGUI.jar" and then use command 'jarsigner' to signed IRMASSvrMgntGUI.jar. There is no problem when I execute 'java -jar IRMASSvrMgntGUI.jar' in the command line. But when I execute this application via Web Start Environment, an "java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver

contents of the manifest file I used to create this jar file are as follows
===================================
Manifest-Version: 1.0
Main-Class: IRMASSvrMgntGUI
Class-Path: classes12.jar

===================================
and file structures in "IRMASSvrMgntGUI.jar" is
====================================
META-INF/
classes12.jar
DBAuthenticateDialog.class
DBConnection.class
IRMASSvrMgntGUI.class
====================================

If you directly include classes12.jar in IRMASSvrMgntGUI.jar, the classloader won't be able to find the classes inside classes12.jar. You should sign classes12.jar separately and include that in jnlp along with your application specific jar. When you're launching your app using "java -jar somefile.jar" then the classpath settings in manifest file are used, but that's not the case when you start using JWS since in this case the classpath is based only on the " <jar href=..." entries in jnlp.

Jar file doesn't read classpath environment variable from windows xp

I created a small program that uses javamail and jdbc driver. I program on Win XP and use java 1.6.04.
When I compiled my classes the program works fine but when I created a jar package the jar file cannot 'see' the classpath that windows has already set.
I have to set the classpath in the manifest file and then it works ok.
Is this normal? I was expecting that the jar file would work just fine without any complication since the classpath is already set in the system?
If you could point to any documentation that covers this it would be great.
Thank you very much.

App runs in Eclipse environment but not from jar file with no error message

When I upgraded my jre to 5.0 my app does not run. After fixing the properties problem I had a few days ago it is now at least compiling and running within Eclpse
However, when I export to a jar file it runs to a certain point and then just goes away with no error message!!! I've narrowed it down to the exact point where it dies but don't understand why it dies and especially gives me no errors whatsoever. It just goes away.
It is creating an instance of a new class when it dies.
Can someone please help me?

Ok, well it doesn't. Anyway, I'm still having the same problems. I can run my jar file to a certain point and then the application just stops. I know this because I've put come message boxes in the application to let me know where in the app the system is.
It always dies when it is instantiating the new class called HeidiFrame; done by:
HeidiFrame heidiFrame = null;
if I put code in between the above line and before the below line, this code will work fine
heidiFrame = new HeidiFrame();
but if I put code after the above line, nothing happens
As I said this all worked fine until I upgraded to Java 1.5
If you look at http://java.sun.com/javase/technologies/compatibility.jsp there are 23 compatibility issues with the new release. We're using xml stuff so that was my first problem and the code wouldn't even compiile. Once I added in libraries, the code compiled and ran beautifully.
However, when creating my jar file so I can deploy this application , I've discovered that the jar file will only run to a certain point, as I've stated previously. So, that's my problem. Not that I can't run it from the command prompt, which I can't, but it's a gui application. I've tried changing things in the classpath file and the manifest to no avail. Nothing changes. The application starts but when it goes to instantiate the HeidiFrame class, which is the class that actually builds the gui it dies and goes bye bye.

JAR File Development environment

Hi Guys,
I?m working on a plug-in for the popular editor ?JEdit? (http://www.jedit.org/).
I?m a very new Java developer and have been asked to help maintain existing code. My problem is not so much the code itself as the development process ? the notes in the project suggest editing and testing the plug-in in a manner that just doesn?t make sense and is an absolute nightmare to debug.
Here?s what the notes say about what needs to be done to make a simple change and then test.
1. Open project in Eclipse
2. Edit code
3. File > Export > JAR File
4. Export to C:\Program Files\jEdit\jars\Plugin.jar
5. Launch JEdit
6. Go to plugin manager and enable the plugin.
This seems to be a rather tedious and takes a long time to test even the simplest change.
Can someone suggest a better way please? Ideally I'd like to be able to add break points that are triggered while using the plugin through JEdit.
I?m sure there?s a very simple approach, but I can?t see the trees through the forest.
Thanks
Warrick

Pray tell kind sir. How do I suggest an alternate method when I don't know of one.
As much as I appreciate the fact that there's a written process, I'm not a little worker drone that's simply going to follow instructions when I can clearly see that they're wasting my time and the companies money.
Developing using a method that does not provide breakpoints and other basic debug features simply doesn't make sense to me. So rather than accept the status quo I'm investigating better approaches.I am glad you are not a drone, but there may be a good reason for the approach they have; I and many of my friends have worked for companies that have contracts with Government Entities and "the approach" has to be certified by an external party before any use of new process can be used. When audited and processes don't match those that have been approved certifications and/or contracts may be pulled or suspended permanently or until recertification takes place.
All I am saying is: check and see if it's OK to change the process, before you possibly waste any more of your time.

Exporting to a jar file in eclipse environment

Hi all,
I am using eclipse as my IDE to develop my swing application. The trouble is the gui reads from a file to get the names it has to store.
When I convert it to a jar file, and execute it the names do not appear. I am guessing that it cannot find the file. Can I not export a file that I imported into my project and send it as part of the jar file? How do I get around this?
Thanks, in advance.

How are you loading the files?
You should try to load your files using their absolute path.
To find the absolute path of your jar application, you can use:
String dir = System.getProperty("user.dir");Then, if the list is in the same directory as your app, you use:
File file = new File(dir+"/list.txt");-----------------------------------------------------------------------
Just a note. If you need to read a file that�s packed inside your .jar application, then you need to read the file using getResourceAsStream. For more information, read this thread
I hope it helps

.jar file is not working properly :developed in NETBEANS

Hi Gurus,
i am using NETBEANS IDE 7.2.
i am developing a project that interacts with databases 10g and COM ports of machine , these all processes are performed by .bat file which i am trying to run from jFramform , code works perfectly .bat file is also called perfectly when i run the project using F6 from the NETBEANS, for testing i placed some dialogue boxes on the form to test it ,
but when i run executable .jar file , form run successfully and dialogue box works perfectly but .bat file is not called by executable .jar file.
this is how i call the .bat file...
String filePath = "D:/pms/Libraries/portlib.bat";
        try {
          Process p = Runtime.getRuntime().exec(filePath);
        } catch (Exception e) {
            e.printStackTrace();
and below is the contents of portlib.bat file
java -jar "D:\SMS\SMS\dist\SMS.jar"
you must probably ask why i am calling a .jar file using .bat file .
reason is that this .jar project sends message using GSM mobile , System.exit(); is compulsory to complete a job and then do the next one ,
if i use the same file to execute this job it makes exit to entire the application (hope you can understand my logic).
that's why i use extra .jar file in .bat file , when single job is completed .bat exits itself and new command is given.
Problem is that code is working perfectly in NETBEANS when i run the project but when i run .jar then .bat file is not working ,
thanks.

Thanks Sir ,
You need to first test an example that works like the one in the article.
There are plenty of other examples on the web - find one you like:
http://javapapers.com/core-java/os-processes-using-java-processbuilder/
I tried this one.
try {
            ProcessBuilder dirProcess = new ProcessBuilder("D:/SMS/SMS/Send_message.bat");
             File commands = new File("D:/SMS/SMS/Send_message.bat");
             File dirOut = new File("C:/process/out.txt");
             File dirErr = new File("C:/process/err.txt");
           dirProcess.redirectInput(commands);
             dirProcess.redirectOutput(dirOut);
           dirProcess.redirectError(dirErr);
             dirProcess.start();
        } catch (IOException ex) {
            Logger.getLogger(mainform.class.getName()).log(Level.SEVERE, null, ex);
as instructed in the article i compiled both the projects at same version or sources and libraries which is 1.7
here is my version details
C:\>javac -version
javac 1.7.0_07
C:\>java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b11)
Java HotSpot(TM) Client VM (build 23.3-b01, mixed mode, sharing)
inside the NETBEANS IDE c:\process\err.txt remains empty and code works perfectly , but when I run executable .jar file( by double clicking on that file in dist directry) then c:\process\err.txt becomes full with this error text and there is no response from calling D:\SMS\SMS\send_message.bat
here is the error text

Program will run with errors, but not at all in a .jar file

First off, here is my program right now:
import java.io.*;
import java.util.*;
import javax.swing.JOptionPane;
public class prune
    public static void main(String args[])
        String steamid="",time="";
        BufferedReader infile = null;
        BufferedWriter outfile = null;
        FileReader fr = null;
        FileWriter wr = null;
        StringTokenizer strtk = null;
        String line = null;
     JOptionPane.showMessageDialog
      (null, "Vault.ini Pruner v2");
     String filepath = JOptionPane.showInputDialog("Enter the filepath to your vault.ini file.");
     String strdeletenumber = JOptionPane.showInputDialog("Enter the number that vault entries under will be deleted");
     int deletenumber = Integer.parseInt(strdeletenumber);
        try
            infile = new BufferedReader(new FileReader(filepath));
            outfile = new BufferedWriter(new FileWriter(filepath));
        catch(IOException ioe)
            JOptionPane.showMessageDialog
      (null, "Can't open vault.ini:" + ioe);
        try
            while((line=infile.readLine())!=null)
                strtk = new StringTokenizer(line);
                steamid = strtk.nextToken();
                time = strtk.nextToken();
                if(Integer.parseInt(time)>=deletenumber)
                    outfile.write(steamid);
                    outfile.write(" ");
                    outfile.write(time);
                    outfile.newLine();
        catch(IOException ioe)
            JOptionPane.showMessageDialog
      (null, "Error:" + ioe);
        try
            outfile.close();
            infile.close();
        catch(IOException ioe)
           JOptionPane.showMessageDialog
      (null, "Error:" + ioe);
            System.exit(0);
}The program is supposed to open a vault.ini file and delete entries with a number lower than specified.
Vault files are set up like this:
STEAMID:X:XXXX 100000
Right now if I run the program through command prompt it erases both the vault.ini and new vault.ini. I am also trying to put it in an executable jar file and when I do that I get a "Failed to load main class manifest attribute" error. Any ideas on what is causing this?

I don't know what is happening. I put your exact code into a small build environment and used a build file for ant that I have and it works just fine. Manifest files are a total pain which is why I use a tool to generate it. I know that the last line has to be blank and that no line can be over a certain length.
You've now spent several days avoiding ant and I got it running with ant in about 3 minutes. I'm really missing something.
For reference, the build file is below should you change your mind. Put your prune.java in a new directory named "src" and save this file below as build.xml in the parent directory of "src". Run the program with java -jar lib/prune.jar
<project name="jartest" default="main" basedir=".">

    <property name="src.dir" location="src" />
    <property name="dest.classes.dir" location="classes" />
    <property name="dest.lib.dir" location="lib" />

    <property name="dest.lib.name" value="prune.jar" />
    <property name="main.class" value="prune" />

    <property name="compile.debug" value="true" />
    <property name="compile.optimize" value="false" />
    <property name="compile.deprecation" value="true" />
    <property name="compile.source" value="1.4"/>
    <property name="compile.target" value="1.4"/>

    <target name="main" depends="compile,jar" />
    <target name="compile">

        <mkdir dir="${dest.lib.dir}"/>
        <javac srcdir="${src.dir}"
                     destdir="${dest.classes.dir}"
                     debug="${compile.debug}"
                     deprecation="${compile.deprecation}"
                     optimize="${compile.optimize}"
                     source="${compile.source}"
                     target="${compile.target}" >
        </javac>
    </target>

    <target name="clean">
        <delete dir="${dest.classes.dir}"/>
        <delete dir="${dest.lib.dir}"/>
    </target>

    <target name="jar" depends="compile">
        <jar destfile="${dest.lib.dir}/${dest.lib.name}"
                basedir="${dest.classes.dir}">
            <manifest>
                <attribute name="Built-By" value="${user.name}"/>

NOT WORKING: Putting a jar file requiring native library in bootclasspath

Hi,
I put my own jar file into the bootclasspath like this:
java -Xbootclasspath/p:myboot.jar TestClass
Some classes in the jar require a native library. For JVM 1.3 on Solaris, I put the native library in $JAVA_HOME/jre/lib/sparc and everything works just fine.
However, when I try the same thing on JVM1.4, I got the following error when my class containing the native methods is called:
Failed to load the native library: myboot_native
java.lang.UnsatisfiedLinkError: no myboot_native in java.library.path
I tried to put that native library in several different directories in jre/lib but still had no luck.
Is there anybody know the solution? Does JVM1.4 allow me to put a custom jar file that requires a native library in the bootclasspath?
Regards,
Eman

Well is your file in a directory included in the java.library.path environement variable. I use java on windows but I have to add the directory where my native library is to the path variable (not classpath) in order to avoid the error you get.

Program run in Netbeans but NOT running as jar file

Dear all ,
i hope any help in this problem.
i am writing program to access parallel port i put next files :
1. [ comm.jar + javax.comm.properties ] in
[ C:\Program Files\Java\jdk1.6.0_18\lib ] and [ C:\Program Files\Java\jdk1.6.0_18\jre\lib ]
2. [ win32com.dll ] in [ C:\WINDOWS\system32 ]
when i run application in NetBeans IDE 6.8 work fine and every think is ok
BUT when i produce jar file , generated jar file does not work [GUI appear but can not get ports on PC]
- I try to set Environment Variable as next :
CLASSPATH = .;C:\Program Files\Java\jdk1.6.0_18\lib\comm.jar
also does not work
any tip please ?
Thanks in advance
Nabil

First of all, leave the lib and jre/lib directories of the JRE alone. Never ever touch them again. Remove any jars you have put there yourself, or better yet completely remove and reinstall the JRE to make sure you put it back in a correct state.
After you do that, learn how to properly work with the classpath in both the IDE and the command line.
Netbeans: you define the classpath by adding jars to the project (right click on the libraries node in the project tree to get the appropriate options).
Command line: this depends on if you run a single class, or you invoke an executable jar.
Single class: you use the -cp command line switch to define the classpath
Executable jar: the jar itself defines the classpath in its META-INF/manifest.mf file. The -cp command line switch is ignored.
Since you use Netbeans, you'll get an executable jar so make sure to learn how such a jar is structured.

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
Reply:
C:\062>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).
