Hi Peter,
First of all goto the below directory
1. /usr/sap/SID/DVEBMGS<instanceid>/j2ee/cluster/server<X>/log and checked the default trace and application log.
2. It may be the deployment has not happened correctly. So please redeploy the component through telnet
telnet <hostname> 5$$08.(Login with j2ee_admin user)
and then run the command
>add deploy
After this run the below command
deploy <location of the file>/SAP_XIESR version_rule=all
Run this command for the next two files and moreover you need to check whether this SCA files are dependent on the java core files, engine files or not.
Please paste content of default trace and application log
With Regards
