Hi,
We have a problem with the application when we try to create a dynamic report
in Excel format. The same application is running on four servers. Servers 1
and 3 are on one computer and the servers 2 and 4 are on another computer.
The problem happens only on servers 1 and 3 and it began occurring about a
month ago. Before that everything was fine and we did not implement any
changes to the application since January.
Below is the text of an error. The strange thing that the error occurs only
when we try to generate large excel file (700 rows, 20 columns). When we
generate smaller reports (100 rows, 10 columns) everything works fine. When we
try to generate about 150 rows report, sometimes program works and sometimes it
does not. So it looks like the problem is related to the size of the excel
files.
The first thing we did is to compare path and classpath on both computers.
They are the same. This is the java application (jdk 1.4.2) running under
weblogic 8.1 server. Weblogic configurations are the same on both machines.
From the error text below looks like the program cannot find the
org.apache.log.Logger class. If this is the case, then how can this program
work fine on small excel files? Does it use the Logger class only to generate
the large files? Could you suggest anything on how to debug this error? For
now we stopped servers 1 and 3 because the help desk gets too many customer
calls and we need to fix the error asap.
Any help and ideas will be greatly appreciated.
Thank you,
Nina Ayzenberg
