Tomcat giving JDK Precedence Over JARs in WAR
I have a web application that uses commons XML (xml-apis-1.3.03.jar). The usage of javax.xml.xpath.XPathFactory.newInstance() works fine in the Eclipse debugger, but when the code is packaged into a WAR and deployed to Tomcat, I get a NullPointerException when javax.xml.xpath.XPathFactory.newInstance() is called: java.lang.NullPointerException at javax.xml.xpath.XPathFactoryFinder._newFactory(XPathFactoryFinder.java:222) at javax.xml.xpath.XPathFactoryFinder.newFactory(XPathFactoryFinder.java:143) at javax.xml.xpath.XPathFactory.newInstance(XPathFactory.java:185) at javax.xml.xpath.XPathFactory.newInstance(XPathFactory.java:99) at com.myorg.myapp.ws.notification.impl.ExtnMessagePatternFilter.accepts(ExtnMessagePatternFilter.java:69) at org.apache.muse.ws.notification.impl.FilterCollection.accepts(FilterCollection.java:64) at com.myorg.myapp.ws.notification.impl.BufferedSubscriptionManager.publish(BufferedSubscriptionManager.java:73) at com.myorg.myapp.ws.notification.impl.NewsNotificationProducer.publish(NewsNotificationProducer.java:38) at org.apache.muse.ws.notification.impl.SimpleNotificationProducer.publish(SimpleNotificationProducer.java:420) at com.myorg.myapp.ws.handler.DDSHandler.run(DDSHandler.java:304) at com.myorg.commons.util.reactor.ReactorAdapter.run(ReactorAdapter.java:19) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) Any idea what might be going wrong here?

Re: Tomcat giving JDK Precedence Over JARs in WAR
Gregor, I am using the following: Tomcat 5.5.20 Xalan 2.7.0 Eclipse 3.2.2 JDK build 1.6.0-b105 I already include xml-apis-1.3.03.jar in the WAR's WEB-INF/lib-directory. However, while I need the class javax.xml.xpath.XPathFactory contained in xml-apis-1.3.03.jar, this class also occurs in the SDK's rt.jar. How can you be sure of which jar gets used by Tomcat for a WAR produced in a Maven build? -David Gregor Schneider wrote: > > 1st, it would help if you let us know which Tomcat / Eclipse-Version... > > Anyways, it should work if you do the following: > > - Copy your xml-apis-1.3.03.jar into your application's > WEB-INF/lib-directory, so that your application's classloader can find > the corrosponding classes. > Tomcat (at least until Tomcat 5.5) does not come with commons xml > > Cheers > > Gregor > -- > what's puzzlin' you, is the nature of my game > gpgp-fp: 79A84FA526807026795E4209D3B3FE028B3170B2 > gpgp-key available @ http://pgpkeys.pca.dfn.de:11371 > > - > To start a new topic, e-mail: users@tomcat.apache.org > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > > -- View this message in context: http://www.nabble.com/Tomcat-giving-JDK-Precedence-Over-JARs-in-WAR-tf4243247.html#a12075436 Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
