runtime classpath using manifest.mf classpath

i built an ear using ant and the its compiling fine. however when i deploy i get the noclassdeffound error in the weblogic server logs. so i added the libraries(jars) in server startup script i.e the server java classpath it works fine.
Please help me how to resolve this runtime classpath issue using ant build. i assume adding classpath in manifest.mf file will help. so far my build.xml is:
Please advice

Usually you don't need to add anything to MANIFEST.MF to make your jars added to application classpath.
Your web application (WAR) files should be directly under EAR.
Overall dependencies (JAR) should be under EAR's APP-INF/lib directory.
Web application own dependencies under WAR files WEB-INF/lib directory. Looking at your build.xml, they should be there.
Before changing you Ant build script, please check these prerequisites and please provide the stacktrace from Weblogic error log.

problem running JUnit tests with Ant in Eclipse. Beginner question

I'm learning these days how to use ant to run automated test folowing this tutorial.
I have JUnit in the classpath of my project. All seem to work fine and I can include it in my classes:
import junit.framework.TestCase; //line20
public class SimpleLattice1DTest extends TestCase{
...
}
My build.xml is:
<?xml version="1.0"?>

When i run it into eclipse I get the following error:
[javac] C:\Documents and
Settings\noname\Documenti\JLife_git\JLife_git\JLife\src\jlife\tests\SimpleLattice1DTest.java:20:

I suppose there's something wrong with it, but I have no idea. Could someone put me in the right direction?

Your javac target doesn't specify anything apart from the source and target directory - it doesn't add any classpath entries; you'll need to add an entry for the appropriate JUnit jar file. See the javac task documentation for more details. You may want to specify the path to JUnit as a classpath attribute, a nested element, or a reference to a path declared elsewhere.

The eclipse classpath is separate from your ant environment. In your build file, when you call javac you need to supply a classpath attribute.
You can define the classpath at the top of the file with the rest of your properties, like this:
<path id="classpath">
<fileset dir="[path to libraries]" includes="**/*.jar" />
</path>
and then use it in each call to javac by setting the classpathref attribute, like this:
<javac srcdir="${src.dir}" destdir="${build.dir}" classpathref="classpath" />

You need to specify the directory that contains your .class files and your external jars (like junit).
e.g.
<!-- Populates a class path containing our classes and jars -->
<path id="dist.classpath">
<fileset dir="${lib}"/>
<pathelement path="${build}"/>
</path>
<!-- Compile the java code place into ${build} -->
<target name="compile" depends="-dirty" description="Compile the source.">
<javac srcdir="${source}" destdir="${build}" includeantruntime="false">
<classpath refid="dist.classpath"/>
<exclude name="${test.relative}/**/*"/>
</javac>
</target>

If you observe the error stack, you will find the following line, just above the error line you mentioned...
[javac] [search path for class files: C:\Program Files\Java\jre6\lib\resource...
This line shows all the jars available in the class path for this ant target execution.
You will definitely not find the desired jar over here i.e. junit-x.x.x.jar (junit-4.8.2.jar)
Now go to eclipse -> Window -> preferences -> Ant -> Runtime -> Global Entries -> Add Jars add junit-4.8.2jar (which you will find in your project lib directory)
If you play around the Ant -> Runtime -> classpath and the classpath related error line in the error stack, you will understand the issue.
Hope this solves your problem.

Hibernate configuration files in an Ant-built WAR file

I have a web app in Eclipse that is working fine. I have built a war file using the ant script below, it works until the program attempts to access Hibernate:
<?xml version="1.0" encoding="UTF-8"?>
<!-- !DOCTYPE removes the warning:
No grammar constraints (DTD or XML schema) detected for the document.
-->
<!DOCTYPE project>
<project name="Audiclave" default="Deploy" basedir=".">
<property name="src.dir" location="src" />
<property name="build.dir" location="build" />
<property name="dist.dir" location="dist" />
<property name="build.classes" location="build/classes" />
<property name="docs.dir" location="docs" />
<property name="web.dir" location="WebContent" />
<!-- Deletes the existing build, docs and dist directory-->
<target name="clean">
<delete dir="${build.classes}" />
<delete dir="${build.dir}" />
<delete dir="${docs.dir}" />
<delete dir="${dist.dir}" />
</target>
<!-- Creates the build, docs and dist directory-->
<target name="makedir">
<mkdir dir="${build.classes}" />
<mkdir dir="${build.dir}" />
<mkdir dir="${docs.dir}" />
<mkdir dir="${dist.dir}" />
</target>
<path id="compile.classpath">
<fileset dir="${web.dir}/WEB-INF/lib">
<include name="*.jar" />
</fileset>
</path>
<target name="compile" depends="clean,makedir">
<javac srcdir="${src.dir}" debug="true" destdir="${build.classes}">
<classpath refid="compile.classpath" />
</javac>
</target>
<!-- Creates Javadoc -->
<target name="docs" depends="compile">
<javadoc packagenames="src" sourcepath="${src.dir}" destdir="${docs.dir}">
<!-- Define which files / directory should get included, we include all -->
<fileset dir="${src.dir}">
<include name="**" />
</fileset>
</javadoc>
</target>
<target name="Deploy">
<war destfile="${build.dir}/audiClave.war" webxml="${web.dir}/WEB-INF/web.xml">
<!-- Include the compiled classes from the compile target -->
<classes dir="${build.classes}" />
<!-- Include any configuration files (hibernate) -->
<fileset dir="${src.dir}" includes="**/*.xml" />
<!-- Include any web content -->
<fileset dir="${web.dir}" />
<lib dir="${web.dir}/WEB-INF/lib" />
</war>
</target>
</project>
The problem I am having is the positioning of the Hibernate config files. In my application they are in :
audiClave\src
but in the deployed app the xml files are in:
audiClave
whereas I think they need to be in :
audiClave\WEB-INF\classes
How do I make the statement:
<fileset dir="${src.dir}" includes="**/*.xml" />
send the files to the WEB-INF\classes directory (if that's where they need to be).
EDIT
Changed the script to include the following and it worked correctly:
<target name="compile" depends="clean,makedir">
<javac srcdir="${src.dir}" debug="true" destdir="${build.classes}">
<classpath refid="compile.classpath" />
</javac>
<copy todir="${build.classes}">
<fileset dir="${src.dir}" includes="**/*.xml,**/*.properties"/>
</copy>
</target>

Ask Ant to <copy> the files into /WEB-INF/classes. You are correct - that's where they belong. Be sure to create the directory path.

Is there an ant task to add a .war to an existing exploded ear

Have a build process that can't be edited and need to pack another war in the the ear that is generated. The ear is exploded so it's just a matter of copying the war file into it but the application.xml needs to be updated so I'd like to find an ant task that will do this. Anyone know of one that will work?

ended up just doing :
<replace file="${j2ee.build.dir}/${j2ee.app..name}/META-INF/application.xml" token="</application>" value="<module><web><web-uri>admin.war</web-uri><context-root>/admin</context-root></web></module></application>"/>
Rather hackish but couldn't come up with another way to edit the file easily

The idea is to create the war and put the file into the ear directory, see the following build.xml code
<?xml version="1.0"?>
<project name="Add war to ear example" default="all" basedir=".">
<target name="init">
<property name="root.directory" value="${basedir}"/>
<property name="classdir" value="${root.directory}/build/src"/>
<property name="src" value="${root.directory}/src"/>
<property name="web" value="${root.directory}/web"/>
<property name="deploymentdescription" value="${root.directory}/build/deploymentdescriptors"/>
<property name="war.file" value="test.war"/>
<property name="ear.file" value="test.ear"/>
<property name="ear.directory" value="${root.directory}/build/ear"/>
<property name="war.directory" value="${root.directory}/build/war"/>
<!-- Create Web-inf and classes directories -->
<mkdir dir="${war.directory}/WEB-INF"/>
<mkdir dir="${war.directory}/WEB-INF/classes"/>
<!-- Create Meta-inf and classes directories -->
<mkdir dir="${ear.directory}/META-INF"/>
</target>
<!-- Main target -->
<target name="all" depends="init,build,buildWar,buildEar"/>
<!-- Compile Java Files and store in /build/src directory -->
<target name="build" >
<javac srcdir="${src}" destdir="${classdir}" debug="true" includes="**/*.java" />
</target>
<!-- Create the War File -->
<target name="buildWar" depends="init">
<copy todir="${war.directory}/WEB-INF/classes">
<fileset dir="${classdir}" includes="**/*.class" />
</copy>
<copy todir="${war.directory}/WEB-INF">
<fileset dir="${deploymentdescription}" includes="web.xml" />
</copy>
<copy todir="${war.directory}">
<fileset dir="${web}" includes="**/*.*" />
</copy>
<!-- Create war file and place in ear directory -->
<jar jarfile="${ear.directory}/${war.file}" basedir="${war.directory}" />
</target>
<!-- Create the War File -->
<target name="buildEar" depends="init">
<copy todir="${ear.directory}/META-INF">
<fileset dir="${deploymentdescription}" includes="application.xml" />
</copy>
<!-- Create ear file and place in ear directory -->
<jar jarfile="${root.directory}/${ear.file}" basedir="${ear.directory}" />
</target>
</project>

Won't <copy> do the job?
What about using <xslt> to modify application.xml then?

Java applet, add jar files to the manifest file

I am doing some thing obvious wrong. I have a simple applet which needs to upload files to server. I have written an ant script to build the jar file. However, the manifest.mf has class-path split into multiple lines.
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Class-Path: lib/commons-codec-1.3.jar lib/commons-httpclien
t-3.1.jar lib/commons-logging-1.0.4.jar lib/plu
gin.jar

My build.xml is :
<project name="ScreenShot" default="dist" basedir=".">

</target>
<target name="clean" description="clean up">

</project>

Check the value of ${jar.classpath}. It seems its value itself is in multiple lines.

Does it not work? It's a bit odd that there are big spaces between each classpath entry but it looks valid.
The manifest specification states that lines must be no longer than 72 bytes and that longer lines should be split and continued on the next line with a leading space.
