Re: [aspectj-users] Bytecode weaving problems

Stalsy,

Is the failing class AddFeedAction.class
on the inpath (target.J2EE.classes.dir
or target.J2EE.all.dir)
in the weave step? Are the J2EE classes need to compiler your application
e.g. javax.servlet.http.HttpServletRequest
on the classpath in the weave step? Which version of AspectJ are you using?

Subject	[aspectj-users] Bytecode weaving problems

Hi All,

I try to weave binary aspects with some java bytecode classes using an
ANT task. I just have source code of the aspects. So I first compile 
separately my aspects and than I weave them with my java ( pre-compiled
.class ) code. My ANT script is:

......
    <taskdef 
resource="org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties">
        <classpath>
              <pathelement location="${lib.dir}/aspectjtools.jar"/>
        </classpath>
    </taskdef>
......
<!-- Aspect compilation -->
    <target name="compile" depends="prepare">
        <ajc destdir="${repos.J2EE.aspect.dir}">
            <classpath refid="classpathAJ"
/>       
            <src location="${repos.J2EE.aspect.dir}"
/>
        </ajc>
    </target>
......
<!-- Bytecode weaving. Classpath includes tomcat, aspectj, and target

application necessary libs -->
<target name="weave" depends="compile">
        <iajc destdir="${deploy.J2EE.out.webinf.classes.dir}"
inpathDirCopyFilter="**/CVS/*,**/*.java">
            <!-- Java classes-->
            <inpath>
                <pathelement
location="${target.J2EE.classes.dir}"/>
                <pathelement
location="${target.J2EE.all.dir}"/>
            </inpath>
            <!-- Binary aspect -->
            <aspectpath location="${repos.J2EE.aspect.dir}"
/>
            <classpath refid="classpath"
/>
        </iajc>
    </target>


So the compilation is ok, but when "weave task" is executed I
receive 
many errors like the following:

[iajc] C:\....profile\AddFeedAction.class [error] can't determine 
superclass of missing type javax.servlet.http.HttpServletRequest
     [iajc] when weaving classes
     [iajc] when weaving
     [iajc] when batch building BuildConfig[null] #Files=0
     [iajc] [Xlint:cantFindType]
     [iajc] (no source information available)
     [iajc] C:\....profile\AddFeedAction.class [error] can't
determine 
superclass of missing type javax.servlet.http.HttpSession
     [iajc] when weaving classes

     [iajc] when batch building BuildConfig[null] #Files=0
     [iajc] [Xlint:cantFindType]
     [iajc] (no source information available)
     [iajc] C:\....profile\AddFeedAction.class [error] can't

     [iajc] when batch building BuildConfig[null] #Files=0
     [iajc] [Xlint:cantFindType]
     [iajc] (no source information available)
     .........

It seems to be a classpath error, but I have included all necessary libs.

Can you help me please? Where I am wrong?

best regards
