create jar for webapp

Question

i'm using netbeans for writing a webapp + filter.

I want to generate a jar file (to place in tomcat/lib folder) for the sake of the filter.

when i compile the project, it generates war file.

is there a way to tell netbeans to generate a jar file instead?

Answer 1

You can add something like this to your build.xml:

<target name="-post-compile">
    <jar destfile="${basedir}/dist/my_web_app.jar">
        <fileset dir="${basedir}/build/web/WEB-INF/classes">

        </fileset>
    </jar>
</target>

Which will build you a jar alongside your war.

EDIT: See Ravindra's answer below for a slight improvement to this method.

Answer 2

An enhancement to @DeadPassive answer - You can get the web app name using the variable ${ant.project.name}

<target name="-post-compile">
    <jar destfile="${basedir}/dist/${ant.project.name}.jar">
        <fileset dir="${basedir}/build/web/WEB-INF/classes">
        </fileset>
    </jar>
</target>

Answer 3

也许修改netbeans使用的build.xml，在生成的jar上添加复制任务。

Answer 4

Create a separate project to generate your .jar file. In that case also I think you have to create the .jar using terminal. You can't create a .jar file for a web project using netbeans IDE, as far as I know.
