Java™ communication timeout settings might need to be
increased before performing a debug on server: If you are having trouble
getting the debugger to connect to your application, you might need to increase
your Java debug
timeout settings. To determine if you are having this problem, check your <workspace>\.metadata\.log file
for the existence of org.eclipse.jdi.TimeoutException messages.
To increase the Java timeout settings, choose Window > Preferences from
the workbench menu bar. Expand the Java node and click Debug.
In the Debug preference page, increase both of the Communication timeouts
(Debugger timeout (ms) and Launch timeout
(ms) - it is recommended that you at least double the default
values for these two fields). If the timeout settings are not increased, the
debugger will hang when you perform a debug on server.For applications
running on WebSphere® Application
Server version 6.0, you can then attempt to reconnect by right-clicking the
server in the Servers view, and selecting Reconnect
debug process from the pop-up menu.
