The exception suggests that this is related to the version of xerces used by the jdk.

When I added my own xerces.jar, xercesImpl.jar, xalan.jar, and xml-apis.jar to
$JAVA_HOME/jre/lib/endorsed, the problem was resolved.

This seems to be caused by JDK 6 and is out of my control as far as fixing it.

Thanks for the suggestion above. An alternative if you are using Apache Tomcat is to put the JAR files in the $TOMCAT_HOME/shared/lib/ directory, then restart Tomcat.

I actually fixed it by adding xalan to WEB-INF/lib probably missing in some dependency' pom because it's definitely used

<dependency>
<groupId>xalan</groupId>
<artifactId>xalan</artifactId>
<version>2.7.1</version>
</dependency>

Xalan itself isn't excluded in any pom's:

$ grep -R -i 'xalan' . (== no results)

Xerces is excluded since it doesn't seem to be needed. From service/pom.xml:

<dependency>
<groupId>org.codehaus.xfire</groupId>
<artifactId>xfire-java5</artifactId>
<version>$

{xfire.version}

</version>

it's probably missing from the xwork2 pom, as you can see from the stack trace it's used there and it's picking up the sun internal implementation that causes the problem

had the same problem. this part fixed it:
<dependency>
<groupId>xalan</groupId>
<artifactId>xalan</artifactId>
<version>2.7.1</version>
</dependency>

don't know why only one of my many appfuse projects had this problem?
