NullPointerException by Upload

[Migrated From Jforum.net]

Hi,

I got this Exception after i tried to upload diferrent type of files for example .zip, .xls
It doesn't depend on the size or the type of file!

java.lang.NullPointerException
net.jforum.JForumExecutionContext.enableRollback(JForumExecutionContext.java:272)
net.jforum.JForum.service(JForum.java:209)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
net.jforum.util.legacy.clickstream.ClickstreamFilter.doFilter(ClickstreamFilter.java:59)

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.20 logs.

Create a directory named "tmp" on the root folder of your website, and give it full write permissions.

It will solve the problem.
