java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
eclipse, logging, noclassdeffounderror, tomcat
Solution
I found the solution here: http://forums.opensuse.org/applications/391114-tomcat6-eclipse-not-working.html
- In Eclipse, Open the "Server" tab.
- Double click on the "Tomcat6" entry to see the configuration.
- Then click on the "Open launch configuration" link in the "General information" block.
- In the dialog, select the "Classpath" tab.
- Click the "Add external jar" button.
- Select the file "/usr/share/tomcat6/bin/tomcat-juli.jar"
- Close the dialog.
- Start tomcat 6 from Eclipse.
Hopefully posting it here will help some poor soul.
Problem
I have actually figured this problem out, but it took me days, so I thought I would paste my solution here to aide others. I am using Fedora 11, and in Eclipse I tried adding a Tomcat 6 server and starting it. I would get the following error: 'Starting Tomcat v6.0 Server at localhost' has encountered a problem. Server Tomcat v6.0 Server at localhost failed to start. Then in my console I got the following: ``` Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:54) Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:323) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:268) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:336) ... 1 more Could not find the main class: org.apache.catalina.startup.Bootstrap. Program will exit. ``` I'll post the solution in an answer below.
