Re: What are these .jar files for

Hi Jeff

I seem to recall that early on when Scott made his POI service program available, he said to put stuff into the /ext directory - that is no longer the recommended thing to do.

If you have nothing that is using the POI stuff, then I'd say do what Coy says.

The service program would have a name like HSSF* some such.

This doesn't apply to the activation.jar and mail.jar, though.

Were you also experimenting earlier that year in sending emails from java? That's what the activation.jar and mail.jar are used for. Very old versions as well. I'd suggest moving them all to another location for the time being and see if anything breaks. Do you have any java based apps running from vendors? If not you're probably pretty safe, just don't delete the files on the off chance you need to figure out where to put them still.

Importance: Low

All,

I'm working with IBM to get DB2 Web Query to run. IBM is telling me that some 'suspect' .jar files in the /qibm/userdata/java400/ext directory could be a problem. I am to identify the applications using these files and move them to the proper applications directory.

I know zero about java. I have no idea where to begin or how to determine if they are even used at all.

The suspect files are

(A bazillion years ago I experimented with something "poi" that was, I think, a way to create spreadsheets with RPG? I experimented only, never used it.)

Thanks for any ideas.
