But, when I run the jar file in the dist folder, I get the following:-

How, to solve this problem? Any help will be appreciated.

Answer 1

You will need to edit your build.xml so that all your used libraries are included in the build process. This will look something like this in build.xml:

<target name="-post-jar">
    <echo>Adding jar: ${reference.myMissingJar.jar}</echo>
    <jar update="true" destfile="${dist.jar}">
        <zipfileset src="${reference.myMissingJar.jar}"/>
    </jar>
    <mkdir dir="bin"/>
    <copy file="${dist.jar}" todir="bin" description="Copy jar file."/>
 </target>

The problem is that while you try to run it in netbeans, the IDE knows about all those nifty libs you use. When using a single jar, that is something different altogether.

Alternativly you might want to state the locations of your used libs in your classpath parameter.

In netbeans do a Clean and build project (shift + f11) if that doesnt help please post more details. Are u using external libs?
