Question

I have written an ANT script and finally am building the jar

here is the building of jar section

<jar jarfile="${destination}/@{name}.jar">
     <fileset dir="${output}">
         <include name="abc/xyz/@{name}/**"/>
     </fileset>
     <zipfileset dir="lib" prefix="lib/"/>
     <manifest>
          <attribute name="Main-Class" value="com.abc.xyz.HelloWorld"/>
          <attribute name="Class-Path" value=".:lib/activation.jar:lib/antlr-2.7.6.jar:lib/asm-attrs.jar:lib/asm.jar:lib/cglib-2.1.3.jar:lib/commons-collections-2.1.1.jar:lib/commons-logging-1.1.jar:lib/dom4j-1.6.1.jar:lib/ehcache-1.2.3.jar:lib/ejb3-persistence.jar:lib/hibernate-annotations.jar:lib/hibernate-commons-annotations.jar:lib/hibernate-entitymanager.jar:lib/hibernate-tools.jar:lib/hibernate3.jar:lib/javassist.jar:lib/jdbc2_0-stdext.jar:lib/jta.jar:lib/mysql-connector-java-5.1.5-bin.jar"/>
     </manifest>
</jar>

Now when I try to execute the package it executes, but whenever data is sent I get an error.

java.lang.NoClassDefFoundError: javax/persistence/NoResultException

But the persistence jar is there in the class-path, I’ve tried all the combinations for the class-path, but in vain.

But in another system I tried without create a jar like

set classpath=.;lib/activation.jar;lib/antlr-2.7.6.jar;lib/asm-attrs.jar;lib/asm.jar;lib/cglib-2.1.3.jar;lib/commons-collections-2.1.1.jar;lib/commons-logging-1.1.jar;lib/dom4j-1.6.1.jar;lib/ehcache-1.2.3.jar;lib/ejb3-persistence.jar;lib/hibernate-annotations.jar;lib/hibernate-commons-annotations.jar;lib/hibernate-entitymanager.jar;lib/hibernate-tools.jar;lib/hibernate3.jar;lib/javassist.jar;lib/jdbc2_0-stdext.jar;lib/jta.jar;lib/mysql-connector-java-5.1.5-bin.jar
java com.abc.xyz.HelloWorld

This works fine.

In Mac when I try like this:

java -cp .:lib/activation.jar:lib/antlr-2.7.6.jar:lib/asm-attrs.jar:lib/asm.jar:lib/cglib-2.1.3.jar:lib/commons-collections-2.1.1.jar:lib/commons-logging-1.1.jar:lib/dom4j-1.6.1.jar:lib/ehcache-1.2.3.jar:lib/ejb3-persistence.jar:lib/hibernate-annotations.jar:lib/hibernate-commons-annotations.jar:lib/hibernate-entitymanager.jar:lib/hibernate-tools.jar:lib/hibernate3.jar:lib/javassist.jar:lib/jdbc2_0-stdext.jar:lib/jta.jar:lib/mysql-connector-java-5.1.5-bin.jar com.abc.xyz.HelloWorld

Also it works fine :(, but the minute I create the jar it stops.

How can I resolve this issue?

The reason for it not works was there not in the class path, the explanation is given here:
