Dear all, thanks for your help regarding to my question about ACE related javascript errors when editing xwiki articles a few days ago. As we figured out it is likely not an issue regarding tot he xwiki system and come in from a particular addon.  Due to the fact, that is is not easily trackable for us which addon is working wrong, we want to setup a second xwiki instance with a new database and without extentions. This is only to ensure the errors weg et is not related to xwiki and to get a closer view to the issue. We tried simply to run a second xwiki using apache tomcat using an webapp directory called "xwiki2" with a xwiki 7.4.2 WAR-Distribution and the default (empty) HSQL Database. But this seems not to work due to the following issue. Could someone help me with fixing that issue? Kind Regards, Sebastian. Here is what the error is about: HTTP Status 500 - Failed to locate an ExtendedURL Resource Type Resolver component type Exception report message Failed to locate an ExtendedURL Resource Type Resolver
