Notes NSD Crash when loading a Java Library

HCL Domino Domino Forum
1

I’m trying to run some lotus script on a button click that will use a 3rd party java toolkit to grab data out of a datastore and put it in some fields in a form.

I am using LS2J to call the java code in question, and put the jar file in a Java script library. (there aren’t any class files or anything there though… just the script library with the jar)

I have Uselsx and use “ScriptLibraryName” in the options for my button, and I have the LotusScript set up to create the appropriate objects and call the methods in the java session.

Unfortunately, when I try to create a new document using this form in Notes, the client crashes with NSD output. The form doesn’t even show up, it just crashes right away.

If I remove the jar file/script library, the form opens fine, but of course it doesn’t work because I need to use that jar library.

Does anyone have any idea what could be causing the crash, and/or who I could get to diagnose my NSD memory dump?

I had also Notes crahes with LS2J when using Arrays as paramaters or return values.I think there is a problem when the array is null and you try to access it.

Are you using arrays?

I was having the same problem with random NSD crashes with LS2J. I was trying use Perl like RegX in Lotusscript using Jakarta-Oro. One particular method returned an array of all matches (like m///) but in certain situations it would return Null when no matches were found = crash.

It was driving me mad and I had no idea what was causing it - Thanks :slight_smile:

Hi

Can you post the FATAL THREAD section of the NSD files with the few lines under it

For example:
