This isn't much help but I have had a somewhat similar experience. I took the war for a working application running on Tomcat 4.0 at work and tried to get it running with Tomcat 5.0 and Eclipse 3.0 at home. It constantly complained about not being able to find log4j, this no matter where I put the log4j jar. Since this isn't something critical to me I haven't focussed on solving it, but have been playing with it intermittently for at least 2 months. But it does seem odd to me that Tomcat in Eclipse can never find it.
You wouldn't think that log4j had to go in some special place in Eclipse. I hope someone else can shed some light. -----Original Message----- From: Glenn Barnard [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 27, 2004 11:11 AM To: [EMAIL PROTECTED] Subject: Problem with logging in Eclipse Hi, I'm new to this list so if my question has been answered previously, please give me a URL to look at---I have tried one without a hit. I am trying to use Tomcat 5.5 in my Eclipse 3.0 development environment. I have a Tomcat plugin which starts Tomcat from a simple icon. In following the limited instructions I've been able to find for installing log4j for Tomcat 5.5, I put commons-logging.jar and log4j.jar in the common/lib directory. As soon as I do that, Tomcat fails during startup with the following stack trace. The messages indicate that Catalog.class is not in the jar files, but I've confirmed that it is in log4j.jar in the correct package. I have brought in the source code, and tried to step through it, but I'm not getting anywhere with that. This AM I tried Tomcat 5.0 and got the same problem. Am not seeing any problem starting Tomcat directly from a DOS prompt. If anyone can help me, I'd surely appreciate it! Let me know if you have any questions about how I configure Tomcat, although I've tried server.xml without editing it. java.lang.ExceptionInInitializerError at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at java.lang.Class.newInstance0(Unknown Source) at java.lang.Class.newInstance(Unknown Source) at org.apache.catalina.startup.Bootstrap.init(Bootstrap.java:208) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:402) Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: No suitable Log constructor [Ljava.lang.Class;@958bb8 for org.apache.commons.logging.impl.Log4JLogger (Caused by java.lang.NoClassDefFoundError: org/apache/log4j/Category) (Caused by org.apache.commons.logging.LogConfigurationException: No suitable Log constructor [Ljava.lang.Class;@958bb8 for org.apache.commons.logging.impl.Log4JLogger (Caused by java.lang.NoClassDefFoundError: org/apache/log4j/Category)) at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.ja va:543) at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.ja va:235) at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.ja va:209) at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:351) at org.apache.catalina.core.StandardService.<clinit>(StandardService.java:53) ... 8 more Caused by: org.apache.commons.logging.LogConfigurationException: No suitable Log constructor [Ljava.lang.Class;@958bb8 for org.apache.commons.logging.impl.Log4JLogger (Caused by java.lang.NoClassDefFoundError: org/apache/log4j/Category) at org.apache.commons.logging.impl.LogFactoryImpl.getLogConstructor(LogFactoryI mpl.java:413) at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.ja va:529) ... 12 more Caused by: java.lang.NoClassDefFoundError: org/apache/log4j/Category at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Unknown Source) at java.lang.Class.getConstructor0(Unknown Source) at java.lang.Class.getConstructor(Unknown Source) at org.apache.commons.logging.impl.LogFactoryImpl.getLogConstructor(LogFactoryI mpl.java:410) ... 13 more _________________________________________________________________ Express yourself instantly with MSN Messenger!
