First off, my apologies if I am sending this email to the wrong list. I
have searched high and low on the web for answers to this question
(including posting on the Java Developer forum), but I am not having any
luck resolving my problem.
I'm running Java Sun System Web Server 6.1 SP5 on Windows Server 2003.
I've deployed a 3rd party web application that works properly. I have
also written/deployed my own servlet/struts web application that works
properly (by itself). The 3rd party application allows for some
customization (i.e., you can add links in that application to point to
other locations). I have added a link that points from the 3rd party
web application to MY web application.
The problem occurs when I do the following steps (in this exact order):
1. Deploy MY war file on the web server.
2. Bounce the web server.
3. Access the 3rd party application in a web browser.
4. Click on a link in the 3rd party application that points to MY
application.
At this point I get an error (see the stack trace at the end of this
email). I DO NOT get this error if I access MY application BEFORE
attempting to access the 3rd party application.
The 3rd party application has included the following jars (among others)
in /WEB-INF/lib:
xercesImpl.jar and xml-apis.jar
And also, the 3rd party application requires the addition of the
following JVM option:
-Djavax.xml.parsers.SAXParserFactory=org.apache.crimson.jaxp.SAXParserFa
ctoryImpl
Things I've tried include:
* Adding xercesImpl.jar, and xml-apis.jar to MY /WEB-INF/lib
directory. Did not help.
* Adding xercesImpl.jar, and xml-apis.jar to the web server
common directory (\Sun\WebServer6.1\bin\https\jar), and also adding the
jar files to my classpath. Did not help.
* Adding the following code to an initialization servlet in MY
application:
System.setProperty("javax.xml.parsers.DocumentBuilderFactory",
"org.apache.xerces.jaxp.DocumentBuilderFactoryImpl"); Did not help.
My guess is that the 3rd party application is loading/using Xerces.
Then when my application loads up, my application is attempting to use a
different XML parser during struts forwarding, and the failure happens
(I should note that the error occurs when my application attempts to
forward from the a servlet to a .jsp).
I've been searching the web for 2 straight days now and I'm no closer to
a solution than when I started. If anybody can help I would REALLY
appreciate it...thx!
