Question

I am using build file to compile my project. I am getting package javax.jnlp does not exist error. My java file doesnot have any errors. I have added javaws.jar to my project build path.

My build file code

<!-- Build file for the project. -->
<project basedir="." default="launch" name="OPRS_JNLP">

  <target name="properties">
    <property name="build" value="build" />
    <property name="dist" value="dist" />
    <property name="src" value="src" />

    <property
      name="classpath"
      value="${java.home}/jre/lib/javaws.jar" />
  </target>

  <target
    name="compile"
    depends="properties"
    description="Compile the project" >
    <mkdir dir="${build}/share" />
    <javac
      debug="on"
      destdir="${build}/share"
      srcdir="com/abhibus/oprs"
      source="1.6"
      classpath="${classpath}" />
    <copy todir="${build}/share">
      <fileset dir="com/abhibus/oprs">
        <exclude name="**/CVS" />
        <exclude name="**/*.java" />
      </fileset>
    </copy>
  </target>

  <target
    name="dist"
    depends="compile"
    description="Create project distribution" >
    <mkdir dir="${build}/jar" />
    <mkdir dir="${build}/jar/lib" />
    <jar destfile="${build}/jar/apsrtcoprs.jar">
      <fileset dir="${build}/share">
        <include name="**/*.class" />
      </fileset>
    </jar>
  </target>

  <target
    name="make-launch-file"
    depends="properties"
    description="Copies and configures the launch file" >
    <copy todir="${build}/jar" >
      <fileset dir="${src}/conf" >
        <include name="**/*.jnlp" />
      </fileset>
    </copy>
  </target>

  <target
    name="launch"
    depends="dist, make-launch-file"
    description="Launch the project using webstart">
    <exec executable="javaws"
      dir="${build}/jar">
      <arg line="-codebase file:. file:./apsrtcoprs.jnlp" />
    </exec>
  </target>

  <target
    name="uninstall"
    depends="properties"
    description="Uninstall the project from the webstart cache">
    <exec executable="javaws">
      <arg
        line="-uninstall http://localhost:9999/apsrtcoprs.jnlp"
        />
    </exec>
  </target>

  <target name="clean"
    depends="properties"
    description="Clean all generated files">
      <delete dir="${build}" />
      <delete dir="${dist}" />
  </target>
</project>

What is going wrong ? When i searched through the forums they say to include the javaws.jar, which i have already done. how to solve this?

Thanks

At a guess, this:

value="${java.home}/jre/ib/javaws.jar" />

should be

value="${java.home}/jre/lib/javaws.jar" />

“lib”, not “ib”
