why don't you try to compile the class it complains about using command
line:

javac yourClass.java

If it still complains, it means that class has some problem.  Most likely it
implements an interface without providing implementation for all the
declared methods or it extends from a super class but doesn't override some
abstract method declared in the super class.

sure!

I'm using Java 1.2.2.0.6, Ant 1.41.

The target producing the problem is:

        <target name="build_compile" depends="create_dir">
                <echo message="${java.vm.version}"/>
                <echo message="${java.vm.name}"/>
                <echo message="${java.version}"/>
                <javac 
                srcdir="${srcDir}" 
                destdir="${destDir}" 
                classpathref="classpath" 
                deprecation="off" 
                debug="off" 
                depend="on"
                verbose="off" 
                failonerror="on" 
                optimize="off" 
                fork="YES" 
                memoryInitialSize="64m" 
                memoryMaximumSize="1024m"/>
        </target>

the classpath ref is: 

        <path id="classpath">
                <pathelement path="${cPatchPath3}"/>
                <pathelement path="${cPatchPath2}"/>
                <pathelement path="${cPatchPath1}"/>
                <pathelement path="${cPath}"/>
        </path>

the properties are:

        <property name="cHome" value="../"/>
        <property name="cPath" value="${cHome}MCBS_Home"/>
        <property name="cPatchPath1" value="${cHome}Release/${cPatch1}"/>
        <property name="cPatchPath2" value="${cHome}Release/${cPatch2}"/>
        <property name="cPatchPath3" value="${cHome}Release/${cPatch3}"/>

any guess?

Thanks sofar!

I don't know. In general it's not a problem to build projects which 
contain
abstract classes without any "tricks" and the error message seems to be a
compiler message, not an Ant error.

Can you tell us more about your environment? OS, Java version, Ant 
version,
maybe the part of the buildfile that causes this problem?
