[opencms-dev] Unable to unmarshal XML content definition schema because Invalid custom widget class CmsCollectorSelectWidget

[Schliemann, Kai]

Hi Arno,
I assume, that

  1.  you are missing a jar in WEB-INF/lib folder or
  2.  there is a jar, but the class is missing
HTH

Betreff: [opencms-dev] Unable to unmarshal XML content definition schema because Invalid custom widget class CmsCollectorSelectWidget

Hi, after importing our 8.5.1 Sources (incl. v8list files) to OpenCMS 10.5.1 i got several errors:

<<

I compared the opencms-vfs.xml from our 8.5.1 server, but i don't found entries for CmsCollectorSelectWidget (i think, it's because this is no "normal" widget).
Second i thought,  a class is missing in /var/lib/tomcat6/webapps/opencms/WEB-INF/classes/com/alkacon/opencms/v8/list/, but on both folders, there are no classes.
On our v8.5.1 server, there are no errors.
And the //system/modules/com.alkacon.opencms.v8.list/schemas/list.xsd file exists already on both server.

Anyone an idea? I spent hours to find anything...
Arno
