Vic, I'm not too familiar with tomcat. You need to compile the java file, create a jar file, and then, I expect, copy the jar file to the xwiki lib directory (I think you will find a xwiki directory under the tomcat "webapps" directory - look under there for the xwiki lib dir). I imagine that the class loader will then be able to find it. String2 has some dependencies (see the "import" statements) - you'll need to make sure that the dependencies are on your class path when you do the compile. I understand that the Oracle 10g JDBC driver behaves differently from the 9i driver. If you are working in a 10g environment I would recommend that you test without the String2 custom type before you go to a lot of trouble with it. I think that some others have been able to use the 10g JDBC driver without the custom type. Please also note that version control on attachments doesn't work properly with my solution. Also, be aware that my Oracle stuff is based on the version 0.9.840 XWiki software and schema. If you are using a later version you may find that there have been schema changes. Someone else on the list may be able to advise on whether there have been any schema changes since 0.9.840.

Does it need to be copied to a specific location? in xwiki.hbm.xml you made a note saying 20.02.2006; JTurner; com.nobody.xwiki.String2 renamed to com.nobody.hibType.String2. (String2 is now in xwiki-hibType.jar - was previously in string2.jar). I don't have this jar file. Thanks Vic
