[chandrashekar.bn]

Hi

Our application has code to parse XML and we are using xerces for doing it. we are getting following error when we execute parser on Jboss AS 7.0.

Caused by: java.lang.NoClassDefFoundError: com/sun/org/apache/xerces/internal/parsers/SAXParser

Can anyone suggest me why we are getting this error.. This function works good on Tomcat 5.5. we have included xerces jar in our application lib foulder and is avaliable in classpath.

I would recommend that you upgrade to latest avaialble AS7 release, which is 7.1.1.Final. If you still run into this problem, then please post the entire exception stacktrace.

Stick with 7.1.1.Final and let's discuss the deployment issue with that version in the other thread you pointed to.

[ricardoarguello]

The anwser is here: https://community.jboss.org/message/717927

You have to add a <system> element to your jboss-deployment-structure.xml file.

Note the xmlns attribute, it has to declare the 1.1 version of the schema:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
          <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
          <deployment>
                    <exclusions>
                              <module name="org.apache.log4j" />
                    </exclusions>
          </deployment>
          <sub-deployment name="eservice.war">
            <dependencies>
                <system>
                    <paths>
                        <path name="com/sun/org/apache/xerces/internal/parsers"/>
                    </paths>
                </system>
            </dependencies>

          </sub-deployment>
</jboss-deployment-structure>
