We actually got this to do what we wanted by changing the BLOB to a
CLOB. The CLOB parameter was accessable by the JSP code.

Hi Mike;

The problem is that MyBlob mow becomes a based variable because all
PARM 
variables are actually based - So now SQL can't find the allocated
storage 
for MyBlob.

You can however help this out by parsing a pointer in the *ENTRY
MyBlobPtr 
and the base a your "MyBlob" with a size on that ...

Regards

Niels;
