Description singhani_naresh 2002-06-17 16:02:18 UTC

I have an applet running under Sun's Javasoft jre 1.2.2_p001. Inside this 
applet we are trying to prompt the user for creating an excel spreadsheet using 
POI (jakarta-poi-1_5_0-FINAL-bin.zip). We have both the jars (commons-logging-
1.0.jar,jakarta-poi-1_5_0-FINAL.jar) in the javasoft/jre/1.2/lib directory.  
When attempting to create a new workbook by using new HSSFWorkbook(), we 
encounter the following error:
Exception occurred during event dispatching:

Can you please let me know what could be causing this error and what is the 
resolution.  A prompt response will be greatly appreciated.

I think this have been fixed in 1.5.1 - please attempt to replicate the error there.

The user did not respond.  I assume this is a duplicate of a number of logging
issues that were fixed in 1.5.1. 

Users should:

1. Try to test against the head or a recent nightly build to see that bugs have
not been resolved

2. At least test against the LATEST version of the production build (meaning if
there is a 1.5.1 test there, not 1.5.0)
