Subject RE: Which javac does ant use in its "javac" task?
Date Tue, 15 Jan 2013 23:05:59 GMT
Actually, currently I am testing with hardcoding the classpath as in below task definition.
 I ultimately want to create a classpath from a string, but that is next question, if I can
get this working.  This is the same path I am using in my commandline javac call

        <!-- Compile Classes -->
        <target name="compile" depends="init, prepare" description="Compile the classes">
                <property name="myclasspath" refid="test.classpath"/>
                    <echo message="myclasspath= ${myclasspath}"/>
                <javac srcdir="${src.paths}"
            <classpath path="/home/ab/antcode/RAD8ProjectsWAS7Server/StarterWeb/WebContent/WEB-INF/lib/*;/opt/local/software/websphere/v7/lib/*;/opt/local/software/websphere/v7/plugins/*"/>

Commandline javac call
export JAVA_HOME
export JDK_HOME
/opt/local/software/websphere/v7/java/bin/javac -verbose -d /home/ab/antcode/build/classes
-classpath /home/ab/antcode/RAD8ProjectsWAS7Server/CSXStarterWeb/WebContent/WEB-INF/lib/*:/home/ab/antcode/build/classes:/opt/local/software/websphere/v7/lib/*:/opt/local/software/websphere/v7/plugins/*:
-sourcepath /home/ab/antcode/RAD8ProjectsWAS7Server/StarterWeb/src -target 1.6 -g:none -source
1.6 /home/ab/antcode/RAD8ProjectsWAS7Server/StarterWeb/src/com/xxx/xxxStarter/event/*.java
/home/ab/antcode/RAD8ProjectsWAS7Server/StarterWeb/src/com/xxx/xxxStarter/vo/*.java > commandline.log

Thanks for any help you can provide.

Without knowing how you are creating the classpath for ant to use, it is impossible to say
why it is not working for you.  It may be something as simple as using the wildcard in a way
that has ant expanding it rather than it being passed through to javac.
