Error page for a custom OAF page in e-Biz

Question

Hi, All
I developed a simple custom search page and deployed it to e-Business (version 12.1.3). I runs well in jDeveloper at the client. This is the steps I did:
1) zip <JDEV_USER_HOME>\myclasses\xx
file structure:
xx\oracle\apps\xx\mem\server
xx\oracle\apps\xx\mem\webui
xx\oracle\apps\xx\schema\server
2) load to application tier $JAVA_TOP
3) chmod -R 775 $JAVA_TOP/xx
4) copy History.xml to
5) $APPL_TOP/xx/mds/webui
6) import MDS: java oracle.jrad.tools.xml.importer.XMLImporter $XX_TOP/mds/webui/HistoryPG.xml -username apps -password apps -dbconnection "(DESCRIPTION= (ADDRESS=(PROTOCOL=tcp)(HOST=db_host)(PORT=1521))(CONNECT_DATA= (SERVICE_NAME=$TWO_TASK) (INSTANCE_NAME=$TWO_TASK)))" -rootdir $XX_TOP/mds -rootPackage /xx/oracle/apps/xx
7) after import completed, bounce the web server
8) reqister a function in e-Biz
Type: SSWA jsp function
HTML Call: OA.jsp?page=xx/oracle/apps/xx/mem/server/HistoryPG
9) put the function in a menu.
When I launch the page, I got error "Error Page You have encountered an unexpected error. Please contact the System Administrator for assistance.
I would be appreciated if anyone can point out which step missed or is incorrect.
