\nwhen trying to execute this code:
\n
\n<c:set var=\"xmlText\">
\n  <a>
\n   <b>
\n    <c>
\n    foo
\n    <\/c>
\n   <\/b>
\n   <d>
\n     bar
\n   <\/d>
\n  <\/a>
\n<\/c:set>
\n<x:parse var=\"a\" doc=\"${xmlText}\" \/>
\n<x:out select=\"$a\/\/c\"\/>
\n<\/code>
\nwhich is straight out of the JSTL examples application in the Java Web Services Tutorial v1.3<\/a>. I’m running the latest version of Tomcat (version 5.0.25) on Windows XP if that matters.<\/p>\n

Can anyone help?<\/p>\n

Update: 06\/03\/2004: Thanks Kris! Adding xalan.jar to the {tomcat}\/common\/endorsed\/ path fixed the problem.<\/font><\/p>\n","protected":false},"excerpt":{"rendered":"
