Hi,

We have been using server side iSpring Java SDK version 5.0 on a windows 2003 server and have Microsoft Powerpoint Presentation 2007 installed on it.

We are experiencing the following exception when we are attempting to convert a pptx file very often. The same pptx file gets converted successfully sometimes. Can you kindly provide any pointers to solve this issue? Looking forward for your response.

Best regards,
Janardhan

The reason of this exception couldn't be determined by the details that you provided.

Please make sure that you don't have any conversion processes running in the background. Don't interrupt one conversion with another, conversion *should* be performed one by one file.

Please mention that sample which goes with iSpring package is compatible with JDK 1.6 ver.

Thank you for responding.

Please let me know the details that should be provided to get to know the reason

I am confident that at any given point of time, only one file is actively being converted and rest of the requests are queued up. Also it is always a single process that handles all the requests. Data and sample tests on our servers confirmed the same

Our servers have JDK 1.6.24 ver installed on them.

Hi, that you for these details. In order to help you we need to examine the error log produced after the conversion error. Please learn how to extract a logfile and the error description it in the developer docs here:

It would be very helpful if you could also provide a PPTX file that can cause this issue.
