Hi, ihave a problem trying to execute an scriptStep

here is my code:

<scriptStep description="Buscamos el campo en concreto y le reemplazamos el onclick" language="javascript"> items = document.getHtmlElementsByAttribute('input', 'onclick', 'cmdEntrar_OnClick(StrPIN.value)').iterator(); while (items.hasNext()) { input = items.next(); input.setAttributeValue('onclick', 'document.mapForm.submit();'); } </scriptStep>

I'm not sure if %WEBTEST_HOME%/lib/optional/*.jar was in my execution classpath... then I add to %WEBTEST_HOME%/lib/classpath.xml file this:

<!-- Mostramos el classpath --> <pathconvert targetos="unix" pathsep="," property="webtest.path.string" refid="webtest.path.id" /> <echo>

============================================================ CLASSPATH de WEBTEST: ${webtest.path.string} ============================================================ </echo>

this code shows me the next list: $/Java/Tools/canoo_webtest/lib $/Java/Tools/canoo_webtest/lib/JavaDiff.jar $/Java/Tools/canoo_webtest/lib/commons-beanutils-1.7.0.jar $/Java/Tools/canoo_webtest/lib/commons-cli-1.0.jar $/Java/Tools/canoo_webtest/lib/commons-codec-1.3.jar $/Java/Tools/canoo_webtest/lib/commons-collections-3.1.jar $/Java/Tools/canoo_webtest/lib/commons-httpclient-3.0-rc4.jar $/Java/Tools/canoo_webtest/lib/commons-io-1.0.jar $/Java/Tools/canoo_webtest/lib/commons-lang-2.0.jar $/Java/Tools/canoo_webtest/lib/commons-logging-1.0.4.jar $/Java/Tools/canoo_webtest/lib/htmlunit-20051102.jar $/Java/Tools/canoo_webtest/lib/jakarta-oro-2.0.4.jar $/Java/Tools/canoo_webtest/lib/jaxen-1.1-beta-8.jar $/Java/Tools/canoo_webtest/lib/jemmy.jar $/Java/Tools/canoo_webtest/lib/js-1.6R2.jar $/Java/Tools/canoo_webtest/lib/log4j-1.2.8.jar $/Java/Tools/canoo_webtest/lib/mailapi.jar $/Java/Tools/canoo_webtest/lib/nekohtml-0.9.5.jar $/Java/Tools/canoo_webtest/lib/pdfUnit-1.0.jar $/Java/Tools/canoo_webtest/lib/pdfbox.jar $/Java/Tools/canoo_webtest/lib/saxpath-1.0-FCS.jar $/Java/Tools/canoo_webtest/lib/webtest.jar *$/Java/Tools/canoo_webtest/lib/optional/bsf-20050219.jar $/Java/Tools/canoo_webtest/lib/optional/bsfIbm2ApacheAdapter.jar* $/Java/Tools/canoo_webtest/lib/runtime/ant-apache-bsf.jar $/Java/Tools/canoo_webtest/lib/runtime/ant-junit.jar $/Java/Tools/canoo_webtest/lib/runtime/ant-launcher.jar $/Java/Tools/canoo_webtest/lib/runtime/ant-nodeps.jar $/Java/Tools/canoo_webtest/lib/runtime/ant-trax.jar $/Java/Tools/canoo_webtest/lib/runtime/ant.jar $/Java/Tools/canoo_webtest/lib/runtime/groovy-all-1.0-jsr-03-SNAPSHOT.jar $/Java/Tools/canoo_webtest/lib/runtime/junit.jar $/Java/Tools/canoo_webtest/lib/runtime/xalan.jar $/Java/Tools/canoo_webtest/lib/runtime/xercesImpl-2.6.2.jar $/Java/Tools/canoo_webtest/lib/runtime/xmlParserAPIs-2.2.1.jar
