Strange error: error creating a pack file: jai_imageio.jar

Classic Servoy
1

Hi, checking our production environment, i saw a new, unfamiliar error message in the server log:

error creating a pack file: jai_imageio.jar

This production environment has been up and runnign with the same solution, same release, same OS, same Java version for months now, never saw this error before.

Couldn’t find anything usefull through Google, except that it has something to do with Image functions in Java.

Except displaying some images, the solution does nothing with images.

I’m kind of clueless…

This library is used by the images plugin. Maybe a reinstall of it (and the images/jai_imageio.jar) solves the error…

3

The images plugin is not used in this environment nor has the environment changed, so why I’m getting these messages all of a sudden makes me wonder…

All plugins etc. are “packed” on the server in server\work\localhost to be transferred to the client. I have seen this error before on Linux and it was a problem with the rights set on the localhost dir. All plugins were transferred to the client anyway, though. So it seems that packing is not necessary, but tried to avoid larger file transfers. Maybe Servoy could comment on why and how these jars are packed?

Paul, not used or not installed? Have you tried flushing jws cache.

Hi Marcel,

It certainly is not used, it’s probably installed, would have to check. flushing the JWS cache? This is on the Server, so I don’t think JWS is involved, is it not?

Patrick, tnx for the explanation. This direction might give a little insight. Would like to hear some further explanation, if possible, from the Servoy crew on this though.
