Hi,

I'm aware that this has appeared in a few forum posts already
(e.g. https://coderanch.com/t/575946 and http://www.jforum.net/posts/list/2209.page) but I am still having a problem.

I am running the latest version (2.1.6), compiled from the src, and I cannot upload large files.

One of the topics above, from about May 2006, says that the offending file is: net/jforum/ActionServeltRequest.java but the header on that says that it hasn't been changed since 2nd Feb 2006???

For the record, the complete error I am getting is:



Any ideas?

Thanks,

/A

This bug was fixed already. There were a problem with the path of file storage.

You can get the CVS version if you want.

Is that the same as the error below? I was attaching 2 small files, 143k. Is there a way to fix it (hack or something) without upgrading just yet? I'm on 2.1.5

It's not the same problem..

As the code of version 2.1.5 is different of 2.1.7, I'm not sure if the exception you reported is still there.. Hope not.

I have the 2.1.6 and here is how I fixed the upload issue.

A) I am 2.1.6 downloaded from the site.

in the JForum directory you have deployed to your web app container create a folder called "tmp" (eg. c:/tomcat/webapps/JForum/tmp). Give it world read/write permissions (or appropriate ownership if your forum is on the web at large) and now all your files will properly be uploaded.

What appears to happen is the DiskFileItemFactory runs out of memory space (its about 100KB) and then it goes to write the file to disk (to save memory and prevent OOM exceptions). If the folder does not exist the file doesn't get written and somewhere in that process a NullPointerException is thrown.

At least this is the theory I am operating on as it fixed the upload issue.
