Question

I’m trying to compile ActionFactory.java file which imports one of my package, RegisterAction.java

Here is the file structure:

/com/masatosan/actions/register/RegisterAction.java

/com/masatosan/redirector/ActionFactory.java

According to the ANT output, I think ANT cannot find RegisterAction.java which is imported in ActionFactory.java

It does compile successfully when I manually run javac on console so this must be some classpath setting that ANT is not looking at.

I know I can add some jar to ANT_HOME/lib but in my case, ANT seems not be able to find ActionRegister.java, not jar or something else. Could anyone help me find out what’s wrong?

ANT script

<project name="CompileMasatosan"  default="main"
    basedir="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\src\com\masatosan">
    <description>

    <!-- this invokes all targets -->
    <target name="main" depends="compileAll" />

    <property name="srcMasatosan" 
        location="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\src\com\masatosan" />

    <property name="dest"
    location="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\WEB-INF\classes" />

    <property name="redirectorSrc" location="${srcMasatosan}\redirector" />

     <!-- complie -->
    <target name="compileAll">
        <javac target="1.5" source="1.5" srcdir="${redirectorSrc}" destdir="${dest}" />
    </target>

</project>

It looks like you are specifying only one “sourcepath” to “javac” – and not both. Maybe you should do

<target name="compileAll">
  <javac target="1.5" source="1.5" destdir="${dest}">
    <src path="${redirectorSrc}"/>
    <src path="${srcMasatosan}"/>
  </javac>    
</target>
