Here is the link to the JAXP (Java API for XML Processing) that is included with the Java 1.5.x sdk. There are specifications, documentation, FAQ's, etc available here.

After seeing this message, I can restart Tomcat and the JSP functions normally. However, if I change the JSP, restart Tomcat before viewing the page, then view the page, I still get the error. For some reason, the error actually has to be thrown before restarting Tomcat fixes it. I know of no other fix. If I change two separate JSPs, I have to view the first page (throwing the error), restart Tomcat, then view the second page (throwing the error again), then restart Tomcat again. It is not enough to throw it once and restart to fix all pages; the error apparently tied to each page. I have discovered that I can make this error go away by applying the JDK 1.4.x compatibility patch, even though my JDK is version 1.5.0_03. This, however, caused me to get the error: java.lang.NoSuchMethodError: org.w3c.dom.Node.getTextContent()Ljava/lang/String; Presumably, the getTextContent() method was not present in JDK 1.4.x, thus the patch causes this error. When I remove the patch, the NoSuchMethodError is resolved, but the original error returns. I first posted this on Bugzilla (Bug 35720), where it was marked as invalid, and I was referred to this list. I posted the error here, and received no helpful information. When I learned of the compatibility patch "fix", I reopened the bug on Bugzilla, but was told: > We do not do user support. With Java 5, you're using the JAXP API as implemented by > your vendor, so look in their docs.We also only support Tomcat on pristine JVM > installations (no custom extensions). > > Please do not reopen the report. I haven't done anything to my JVM except install it directly from Sun. I've only customized Tomcat insofar as I have added the appropriate jars for JSTL and JavaMail. I don't know what the JAXP API is, nor who my vendor for it might be. I'm not even sure who I'm being told to ask about this anymore! Can somebody please at least steer me in the right direction with this? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
