http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22300 Classloader problem when digester jar is in common/lib as well Summary: Classloader problem when digester jar is in common/lib as well Product: Tomcat 4 Version: 4.1.27 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Under certain circumstances it may be desirable to have a digester jar in common/lib. Because of the well know class loader hierarchy Tomcat prefers the digester jar in common/lib over server/lib on startup. The classes digester tries to build from the XML are accessible over the server/lib class loader only. Its standard class loader is the one from common/lib though. Thus it can not find those classes resulting in the following exception: Catalina.start: java.lang.ClassNotFoundException: org.apache.catalina.core.StandardServer java.lang.ClassNotFoundException: org.apache.catalina.core.StandardServer at org.apache.commons.digester.Digester.createSAXException(Digester.java:2540) at org.apache.commons.digester.Digester.createSAXException(Digester.java:2566) at org.apache.commons.digester.Digester.startElement(Digester.java:1276) at org.apache.crimson.parser.Parser2.maybeElement(Parser2.java:1535) at org.apache.crimson.parser.Parser2.parseInternal(Parser2.java:534) at org.apache.crimson.parser.Parser2.parse(Parser2.java:318) at org.apache.crimson.parser.XMLReaderImpl.parse(XMLReaderImpl.java:442) at org.apache.commons.digester.Digester.parse(Digester.java:1548) at org.apache.catalina.startup.Catalina.start(Catalina.java:449) at org.apache.catalina.startup.Catalina.execute(Catalina.java:400) at org.apache.catalina.startup.Catalina.process(Catalina.java:180) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:203) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
