Error ODE v1.x Server failed to start at localhost - Eclipse

Problem 
I faced the problem of failing to start the ODE v1.x.(eclipse - Kepler relase) The error message either

1. Server port In Use 8080-Http :- Reason there might be some other service running on the port you are trying to start he ODE (for example 8080 in this case)

2. A Java Exception has occurred - see the following screen shot. or "Server Ode v1.x Server at localhost failed to start."

I am not going to explain the reason behind the error. i can say the server classpath missing one .jar. (tomcat-juli.jar)

solution

Double click the ODE server instance in eclipse - window opens and shows the overview of the server -> click the Open launch configuration (see the screen shot below)

A window pop up to edit the configuration, click the classpath tab , you can see under the user entries there is a jar called bootstrap.jar. 

but the problem is beacuse of the missing jar - "tomcat-juli.jar". So we need to add the manually, click on the Add External Jar and go to the %CATALINA%/bin folder (C:\Program Files\Apache Software Foundation\Tomcat 7.0\bin - in my case) and add the "tomcat-juli.jar"

once you added the "tomcat-juli.jar" click OK, and start the server. Restart the server. It should start without any problem. 

I found the answer from the following links
