Error on documentum Search in webtop

DocBuilder

Hi,

Query execution error for $docbase_name$ :  Unable to process query

Query execution error for $docbase_name$ :  [DM_VEL_INSTANTIATION ERROR]error : "Cannot instantiate java class"

Steps I have taken till now:

1. Cleared the BOF cache.Cleared the cache both on the content server as well as the app server.

2. Since I also got this error

"ERROR [http-80-1] com.documentum.web.common.Trace - No of formhistories in the session :8B5041A765C6C822E4C3D4B90AA6EC6A, exceeds threshold, no of formhistories in the session: 50, confiugred threshold: 50"

I changed the FormProcessProp.Properties file is located under WEB-INF\classes\com\documentum\web\form\ and changed the entry

maxNoOfFormHistoriesThreshold=50 to maxNoOfFormHistoriesThreshold=100

3. I also checked the permissions on Cabinets/System/Modules/SBO. dm_world has read permissions on it.

4. Also performed the following steps:
