https://community.jforum.net/posts/list/2.page JForum - http://www.jforum.net
A friend was going to try using jforum for his site. I was going to tell him how to set it up and created a project in Netbeans and took it to the install.jsp. I closed it and never completed the install.

Then when I tried to load my app NetBeans also started the temp project which had also switched the java version being used by glassfish. After correcting those problems, I still have a problem with jforum.

Could starting the install of a different project cause problems with C3P0?

When I try to access jforum it has a long hang but eventually reports:

Severe: WebModule[/MapBake8]StandardWrapper.Throwable

Did you start MySQL server before you launched JForum?
]]> https://community.jforum.net/posts/preList/129/496.page https://community.jforum.net/posts/preList/129/496.page GMT
It was just a coincidental change in my dynamic IP address and I needed to set a security rule for the new address.

Thanks for your help.
