RE: [dom4j-user] Exception getting SAX parser

Title: Message

It's from an application.   Ok, so I took xerces and xalan out of my classpath and recompiled everything.  It compiled, but running gave me this:   java.lang.NoClassDefFoundError: org/xml/sax/helpers/XMLFilterImpl  at java.lang.ClassLoader.defineClass0(Native Method)  at java.lang.ClassLoader.defineClass(ClassLoader.java:499)  at java.lang.ClassLoader.defineClass(ClassLoader.java:437)  at junit.runner.TestCaseClassLoader.loadClass(TestCaseClassLoader.java:104)  at java.lang.ClassLoader.loadClass(ClassLoader.java:264)  at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:324)  at com.a4networks.server.Configuration.saveConfig(Configuration.java:87)  at com.a4networks.server.ConfigurationTest.testPutGet(Unknown Source)  at com.a4networks.server.ConfigurationTest.runTest(Unknown Source) Anyway, javap doesn't find any xerces classes, so I guess java 1.4 doesn't include them.  Any other ideas? -----Original Message----- From: James Strachan [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 16, 2001 5:04 PM To: David Hooker; [EMAIL PROTECTED] Subject: Re: [dom4j-user] Exception getting SAX parser Hi David   I think JDK1.4 comes with crimson and xalan so you might want to try removing xerces,jar and xalan.jar from your classpath and trying again. Is this from an application or a servlet or EJB?
