I can't build the project sample "Synchronous BPEL Process"

I would like to test the sample "Synchronous BPEL Process". After adding the JBI module (add project jar file) to the composite application, I try to build the project.

Here is the log produced :

C:\Sun\Formation\SOA\SynchronousSample1\SynchronousSample1\nbproject\build-impl.xml:160: Found compilation errors.
BUILD FAILED (total time: 1 second)

Here is line 103 of build-impl.xml file :

    <ant target="dist_se" inheritall="false" dir="${project.SynchronousSample1}"/>

extract from the following block :

  <target name="deps-jar" depends="init" unless="${no.dependencies}">
        <ant target="dist_se" inheritall="false" dir="${project.SynchronousSample1}"/>
        <basename property="se.jar.name" file="${reference.SynchronousSample1.dist_se}"/>
        <unzip src="${project.SynchronousSample1}/build/${se.jar.name}" dest="${src.dir}/../bindingComponentASA">
            <patternset>
                <include name="**/*.wsdl"/>
                <include name="**/*.xsd"/>
            </patternset>
        </unzip>
    </target>

Here is line 160 of build-impl.xml file :

  <validate-project buildDirectory="${basedir}/${build.dir}" sourceDirectory="${basedir}/${src.dir}" projectClassPath="${javac.classpath}" buildDependentProjectDir="${basedir}/${build.dir}/dependentProjectFiles" classpathRef="ant.task.classpath.validation"/>

extract from the following block :

 <target name="pre-dist">
        <!-- Empty placeholder for easier customization. -->
        <!-- You can override this target in the ../build.xml file. -->
        <mkdir dir="${build.dir}"/>
        <!-- run the validation task here. -->
        <validate-project buildDirectory="${basedir}/${build.dir}" sourceDirectory="${basedir}/${src.dir}" projectClassPath="${javac.classpath}" buildDependentProjectDir="${basedir}/${build.dir}/dependentProjectFiles" classpathRef="ant.task.classpath.validation"/>
        <!-- copy all files from project source directory to build directory. -->
        <copy todir="${build.dir}" preservelastmodified="true">
            <fileset includes="**/*.bpel,**/*.wsdl,**/*.xsd" dir="${src.dir}"/>
        </copy>
        <!-- generate portmap.xml in build directory. -->
        <generate-jbi-descriptors buildDirectory="${basedir}/${build.dir}" sourceDirectory="${basedir}/${src.dir}" projectClassPath="${javac.classpath}" classpathRef="ant.task.classpath.models"/>
        <!-- extract wsdl/xsd files from dependent projects and copy to build/dependentProjectFiles. -->
        <delete dir="${build.dir}/dependentProjectFiles"/>

        <dependent-project-file-extractor buildDirectory="${basedir}/${build.dir}/dependentProjectFiles" sourceDirectory="${basedir}/${src.dir}" projectDirectory="${basedir}" projectClassPath="${javac.classpath}"/>
    </target>

If anyone has an idea. Thanks ...
