1: Error creating application
Posted by Gonzalo López on 09/14/09 11:02 AM
From a basic installation of OpenACS I installed dotlrn from the repository. The installation was OK, but when I tried to add the application I got an error response: "We had a problem creating the application". The error.log says:

It is important to say that this error only happens when I try to mount the dotlrn application. With the File-Storage package everything works OK

Hi Gonzalo,

dotlrn is not meant to be mounted on an existing instance of OpenACS, it requires a specific installation.

Once you have the code on your machine, cd to your openacs root directory and copy packages/dotlrn/install.xml there. Then start your server to begin with the installation.
