Exception in thread "main" java.lang.NoClassDefFoundError during starting your Tomcat in Eclipse

[areeg samir]

If you are using Tomcat v.6 or v.7, you probably get the following error:
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.

This error occurs because it misses the tomcat-juli.jar in the Launch environment
So to solve it do the following steps:

1. Double click on the installed Ode v1.x Server in the 'Server' View.
2.  Click on Open launch configuration. figure1
3. Choose  Classpath tab > Add External JARs > [your TOMCAT_DIR]\bin\tomcat-juli.jar. figure 2,3,4
4.  Then Apply then OK.
5. Start your Ode v1.x Server in the Server View by right clicking on it > Start or press the start icon.

Ode server at localhost

click on User Entries then add external jars

Choose tomcat-juli.jar

click Apply the OK

Start your server up by clicking on start or icon

Strange.  The fix works to start the ode server.

However, when I stop or restart the ode server I get the error again by right-clicking on the ode server in the Eclipse Servers window:

And when I close eclipse it hangs with an error about .metadata/logging and i have to use Force Quit to kill it.
