Error occurred when trying to access DC in web dynpro


Have everyone ever encountered an error saying <b>"Unhandled exception caught in event loop"</b> when trying to access DCs in web dynpro? I tried to add a new action to my main compnent after a used web dynpro component (DC) was added but the web dynpro would shut down automatically. The web dynpro would shut down accidentally and automatically even when I clicked the interface controller. Some times, the error log would repport "<b>org.eclipse.swt.SWTError: No more handles</b>" has driven me crazy. I could not go further. Can someone tell me what I have done wrong to get these errors?!!

Dear Zita,

I error is related tot he message which you get "No more handles".

This definitelly means that there is a bug and old files are not closed , thus the number of handles on OS level is exceeded.

The exact way to debug the "handles" leak is with applying SAP JVM Profiler, using the I/O Analysis feature.

Best Regards,
