Our Dell server crashed today

One of our Dell server crashed today after almost four years on, working around the clock 24x7. In one minute I was attended by technical support that was one of the best support I have received over the phone in years. Are to be congratulated for their quality service and products. The server has reached the end of useful life and we'll buy another Dell again, they have the best servers. I recommend it!

Error: java.lang.NoSuchMethodError: org.mortbay.thread.Timeout.

After installing the 2.1 GWT (google web toolkit) in Eclipse received the following error:

Exception in thread "main" java.lang.NoSuchMethodError: org.mortbay.thread.Timeout.(Ljava/lang/Object;)V

This indicates duplicate libraries.

To solve:

In eclipse, Press CTRL + SHIFT + T and search for: org.mortbay.io.nio.SelectorManager

Probably you will find more than one reference.

In my environment were found two:

-> com.google.appengine.eclipse.sdkbundle.1.3.8_1.3.8.v201010161055

-> com.google.gwt.eclipse.sdkbundle.2.1.0_2.1.0.v201010280102

In Java:

- 50% of problems are classpath,

- the other 50% of the problems resides in your own code

- and the remaining 50% is with the user ;o)
