Building a jar

I think I might have missed something here. I'm using the JMF with Java 1.6. I've created a jar, however it doesn't work on other computers. I'm sure it's something with the JFM jars, however I'm not sure. The jars are included in my project, however the exe doesn't work. What am I doing wrong?
Any help?

Are you using cross platvorm libraries in you jar file ?
You do know that when using windows performance back they relay on windows shared libraries dll -s.
They are located in c:\windows\system32\jm* and jsound.dll and when performance back is not installed on computer it probably wont work.
With application it's easy just create an installer which copies dll files into system32 directory.
I have made an installer which copies jmf jars to program files and dll -s to system32.
Then i use exe which launches java jvm.
Works on every (windows)computer and it does not matter if jmf is installed or not.
Ethan, i'm not sure you have the same problem that previous poster had.
What exceptions you get when you run this jar file from command prompt?

How can I build automatically jar with Eclipse?

Hi,
I try to build automatically jar file each time when I save my project.Until now I used right click and Export to jar but that take me more time and it is not efficiently.I have try to configure an new builder from project->properties-> builders options but when I Clean it give me the following error:
The file does not exist for the external tool named MY_Builder
Please help me If you can, all that I try to find is to generate automatically jar file each time when I save or clean the project,no matter the method as long as it's working on Eclipse
Many thanks,

Hello,
But How can I do that ? I make a new ant compiler but I have some errors:(. I don't know how to configure this ant.Can u help me please?

How to build a jar file so the program can access its resources folder?

I have a java program written by someone else in which I have made a trivial change (I changed the background color). The jar file runs but it does not find one of the resources file.
Here is the project folder's structure
mainClass.txt (manifest text file)
folder resources (includes file Java does not find: order.txt, a text file)
folder CFPT ( includes .class files)
folder cpl (includes .class files)
folder results
I tried
jar cvmf mainClass.txt CFPT0.jar CFPT/*.class cpl/*.class resources results
I get a lot of "adding: resources/..."
including the one pertaining to the files which is later not found
adding: resources/order.txt(in = 411) (out= 169)(deflated 58%)
the code that chokes right now is the following,
Object i = new Object();
InputStream is = i.getClass().getResourceAsStream("/resources/" + resourceName);
when I run java -jar CFPT0.jar the program runs
but it soon gives an error, cannot find resourceName order.txt (is == null)
I have Core Java Volume 1 page 498 but it does not help me figure out what I am doing wrong.
Can somone help me build the jar file correctly so the program can find its resources?
Is this a classpath issue? What do I need to do?

My last mainClass.txt file content:
Main-Class: CFPT.CFPTRunner
Class-Path: ./resources ./results
I also tried
Class-Path: resources results
Initially I only had the first line.
I put back /resources in the java file as the / is necessary to indicate absolute path.
Otherwise it looks relative to calling class.
I tried adding the path on the second line of the manifest file per Wikipedia example
http://en.wikipedia.org/wiki/Classpath
I looked at
http://java.sun.com/javase/6/docs/technotes/guides/lang/resources.html
If you use the -sourcepath option, the compiler searches the indicated path for source files; otherwise the compiler searches the user class path both for class files and source files.
http://java.sun.com/javase/6/docs/technotes/guides/lang/resources.html
resources
I took out the -d classes and compiled the .class files right with the java files in case that was the problem
javac -classpath . CFPT/CFPTRunner.java
jar cvmf mainClass.txt CFPT0.jar CFPT/*.class cpl/*.class resources results
java -jar CFPT0.jar
Still no go

Building a jar in an ant build.xml file

Hi,
i previously used netbeans to create a jar that you could doubleclick to have it automatically started (win 2000).
The jar also included other jars like log4j, jdom and so.
In Netbeans, i first made my project and those jars available via the filesystem. Then i just made a new jar, added my project and the startpoints of the other jars. For instance for the jdom.jar, i selected the org and everything beneath.
Then i generated a standard manifest file and added this line:
Main-Class: <package>/<mainclass>
This worked ok fine.
Now, for my question: i'm trying out ant and want to achieve the same as above. Building my project is not a problem. I specified the dependies on other jars like this:
<target name="compile" depends="init" description="compile">
    
    <javac srcdir="${src}" destdir="${build}">
      <classpath>
        <pathelement location="lib/jdom.jar"/>
        <pathelement location="lib/log4j-1.2.7.jar"/>
      </classpath>
    </javac>
</target>Compiling doesn't produce an error.
However i can't seem to figure out how to build a jar where the root of each jar is included in the content of my own jar so i don't have to distribute the jars seperately.
This is what i had so far for my jar:
<target name="dist" depends="compile" description="generate" >
    
    <mkdir dir="${dist}/lib"/>
    
    <jar jarfile="${dist}/lib/customer-${DSTAMP}.jar"
         basedir="${build}" manifest="${conf}/manifest.mf"/>
</target>My manifest file:
Manifest-Version: 1.0
Main-Class: customer/clientAny idea of how to add the content of another jar to my own jar?
Thanks

How to improve ejbc performance while building a jar

Hi All,
We are wasting valuable time in in development stage while building a
jar which
has quite a few beans.
We found out that ejbc is taking up most of the time. For example, a jar
which has
about 30 beans ejbc is taking up about 5 minutes to build the complete
jar.
We are not sure if we are doing something wrong or ejbc itself is slow ?
It would help us tremendously if you can identify the problem and help
us
expedite the process.
Thanks in advance
-Sheshi

You could put each bean in it's own JAR file, then only build
the bean that is modified. Guaranteed to be 30 times faster.

Why use ojdeploy when building ViewController jar/war?

Hi,
It is known that ojdeploy is the recommended way to go when building/deploying an ADF app. The advantages are stated in many blog posts in the web.
IMHO the most important reason for using ojdeploy instead of javac when creating an EAR is that javac CANNOT validate your BC. This means for example that if you refactor-rename an attribute of a VO and then commit only xml and not the related View Row Impl class, the build in your CI server will succeed if using only javac and fail if using ojdeploy (as it should be). So ojdeploy is the only way when building jars of Model projects if you want to be 100% sure the you have valid ADF code.
The question is if the is a similar reason for using ojdeploy when building ViewController jars/wars??
Thanx in advance for any feedback.

ojdeploy makes changes to your descriptors javac or jar does not know about. Actually nobody knows about the changes as you have to look into the war to see them. I'm not even sure that they are documented.

Not able to build osb jar using osb 10.3

Hi All,
I am working on developing an osb jar from workspace(osb 10.3) using ant scripts.When i am trying to invoke an ant with target "export" it show an error "Java returned :13".I went through the entire post sent by respected people over the forum but i am not able to solve it.
Script which i am using :
<project name="ConfigExport">
<property file="./build.properties"/>
<property name="eclipse.home"
value="${bea.home}/tools/eclipse_pkgs/2.0/eclipse_3.3.2/eclipse"/>
<property name="weblogic.home" value= "${bea.home}/wlserver_10.3"/>
<property name="metadata.dir" value="${workspace.dir}/.metadata"/>
<target name="export">
<available file="${metadata.dir}" type="dir"
property="metadata.dir.exists"/>
<java dir="${eclipse.home}"
jar="${eclipse.home}/plugins/org.eclipse.equinox.launcher_1.0.1.R33x_v20080118.jar"
fork="true"
failonerror="true"
maxmemory="768m">
<arg line="-data ${workspace.dir}"/>
<arg line="-application com.bea.alsb.core.ConfigExport"/>
<arg line="-configProject ${config.project}"/>
<arg line="-configJar ${config.jar}"/>
<sysproperty key="weblogic.home" value="${weblogic.home}"/>
</java>
          <antcall target="deleteMetadata"/>
</target>
     <target name="deleteMetadata" unless="metadata.dir.exists">
<delete failonerror="false" includeemptydirs="true"
dir="${metadata.dir}"/>
     </target>
</project>
It seems that on debugging the error in eclipse log say for ex: C:\bea\tools\eclipse_pkgs\2.0\eclipse_3.3.2\eclipse\configuration\
show me an error saying : "java.lang.RuntimeException: Application "com.bea.alsb.core.ConfigExport" could not be found in the registry."
It seems that com.bea.alsb.core.ConfigExport not able to find the class which is used to export an osb jar.Moreover in the thread posted basically talks about osb 11 so i am not able to find many folders like middleware,oracle,osb.home.
Please let me know what is the possible solutions for this in osb 10.3.
Regards,
Rajeev Goel
(Application Developer)

see here Export from OEPE not working for an answer, that I copy/paste here:
You have to verify if your OEPE instalation has the following file in the directory dropins (e.g C:\Oracle\middleware\oepe11.1.1.3\dropins)
filename:
oracle.osb.ide.link
content:
path=C:/Oracle/Middleware/Oracle_OSB1
Under the Oracle_OSB1 you have an eclipse directory with needed plugins:
e.g. C:/Oracle/Middleware/Oracle_OSB1/eclipse is not empty
This is only a sample directory naming from Windows installation, I had a problem on RHEL 5.3 where installer did not put such files.
Then I took the files from Windows installation.
I suspect the files are installed "automatically" but I am not sure when.

How to configure maven to build EJB Jar?

Hi!
I would like to know how you setup Maven2 or alternatively Ant to build an EJB Jar.
I have managed to do this in Maven by adding required jars to my local repository and added dependencies in the pom.xml file. This, however, do not seem like a good solution. I would like set some kind of classpath for maven to look for all libraries included in my application server.
Could you please help me to solve this and I will be most grateful?!

Cannot build EJB jar file in NWDS

hello,
I changed java beans file, and tried to build jar file again, then the "build EJB archive" context menu is disabled so I can not make EJB jar file!
So frustrated.. NWDS recognizes the changes in the java files , right? How come there 's no Build menu..
Is there any pre-requisite to enable the menu?
I have no idea how I can build jar file..
Please give me a advice.. Thanks~!

You might check the weblogic.developer.interest.ejb.tools new group.
Make sure that the tool doesn't leave this ejbcgen directory around. It
should delete
that temp dir. When it doesn't it keeps all the old generated stuff around
and your changes won't be
reflected in the new jar.

Hi,
I have a problem with the EJBDeployerTool. When I want to update
a class file (for example, because I corrected any problem), the
deployer tool doesn't update the file correctly. It keeps the
old version of the class file.
In order to update a jar I have to copy the newer version in the
.ejbdeployer/provider-projects directory by hand. Is it a bug?
Is there any other way to do this? We are wasting too much time
in this task, instead of programming :_(

Problem building EJB jar file using Eclipse

Hi,
Here's my file sturcture.
ejb\x\y\z\test\
ejb\x\y\z\test1\
'ejb' is the root directory.
The java source files under 'test' have a package name x.y.z.test.
The java source files under 'test1' have a package name x.y.z.test1.
I want to build a EJB jar file for 'test' and 'test1' separately. In eclipse when I create an EJB project, I specify the root folder as the source in the java build path settings. So the project explorer in Eclipse shows both the packages since they are under the same root folder. When I try to do 'Export - EJB Jar File', it includes both the 'test' and 'test1' in the .jar. Is there a way to build them separately ?
Thanks,

As far as I know, there is no way in Eclipse to specify a package prefix for a source folder. Assuming that you are not using an operating system with support for symbolic links at FS-level, the only way I can think of solving your problem is via linked folders and includes/excludes.
1. Create two ejb projects in your workspace. Specify locations somewhere independent of where the root of your source tree is located.
2. Right click on proj1 and select Properties / Java Build Path / Source.
3. Click Link Source and specify the location to your source root on disk. Click Next.
4. In the inclusion patterns section, add a pattern that captures classes appropriate for that module. Click Finish.
5. Delete the original source directory that was created during project creation before leaving Build Path configuration dialog.
6. Repeat steps 2-5 on the second project, except specify a different inclusion pattern.
This should produce a project structure that Eclipse will be happy with, but you have to be a little bit careful. Even though you filtered out classes from the view of the java compiler for a particular project, you will still see them listed in the various navigational views (such as Package Explorer or Project Explorer). Don't modify these filtered out files. The project that is supposed to be building them will not react to changes in the other project. You will have to manually refresh (right click on project and select refresh) the other project before the java compiler will see changes.
Hope this will help you out.

Building ejb jar

Ant help - building a jar with image files.

I have a jar that contains a handful of image files in a "resources" folder. I used the following command:
jar -cf resources.jar resources/Now I need to make ANT do the same thing. I tried the following, with no success:
<property name="build" location="bin"/>
<property name="dist" location="jars"/>
<jar jarfile="${dist}/resources.jar" basedir="${build}">
<arg value="-cf" />
</jar>In the above example, the "bin" directory contains the "resources" directory that I want to put into the jar. Basically, I need to know how to specify the "-cf" args, and how to specify the target directory as "resources." Can anyone tell me how this is done?
Thanks.

Hi micah,
I can just give you an hint:
With Ant each tasks has its own properties wich are described in xml. So for your jar generation you should look for the possibilities in the description of the ant task in.
http://ant.apache.org/manual/index.html
I guess you need some <include> elements in your <jar> target.

Building ear, jar and war

Do I need a special tool to build the ear, jar and war files necessary for a J2EE application?
And where can I find such tools?

you don't need a special tool, with the jdk you have a command jar who make special file. The syntax is jar -cvf name.jar <directory>. jar only display you the correctly syntax.
For the ejb.jar you have to respect the tree of the application with the directory meta-inf
For the project.war you do hace the web-inf directory with web.xml
For the project.ear you have to add the .jar and the .war into and a dirctory meta-inf with the fila application.xml
If you find this too difficult some products like Jdevelopper make this very correctly

This question is quite different from your original question. Is it your intent to convert the application into an applet or are you interested in creating an [executable JAR file|http://java.sun.com/javase/6/docs/technotes/guides/jar/jarGuide.html]? If it's the latter, when bundling your application in a JAR file you'll need to update the [JAR file manifest|http://java.sun.com/javase/6/docs/technotes/guides/jar/jar.html] with a Main-Class entry. If it's the former, the following link will be helpful:
