Hi Nilesh,
I am using SAP BC 4.6 and came across this issue when I installed a Service Pack.
I had the following Folder/java structure setup:
FolderJava
|-FolderJava2
| |-JavaService2
|-JavaService1
This worked fine before the Service pack was applied.
After the service Pack I got the same Error you describe, I had to change my Folder/JavaService structure to be:
FolderJava
|-FolderJava2
__|-JavaService1
__|-JavaService2
OR
FolderJava
|-JavaService1
|-JavaService2
Hope this helps, it was a big pain to change all these services, I had to rea-slign the folders, then verify/modify all the flow Services that used these Java Services.
Good Luck.
Cheers.
