When building a new SQLJ application with DB2 V72 FP4 an 
error is received during customization and the application
hangs. This is caused by a defect introduced in V72 FP4.
This will only affect new applications created on V72 FP4.

SYMPTOMS
Application receives a "SQl0501N UPDATE or DELETE is not allowed
against the specified cursor. SQLSTATE=42828 " during customization. 
Subsequently, running the application will cause it to hang 
indefinitely.


CAUSE
The problem is caused by a a defect that retrieves an incorrect column
count for a cursor. This patch addresses this problem by 
retrieving the correct column count.

WORKAROUND
Build the application against any previous FixPack, i.e V72 FP3 or FP2
and then continue running it against FP4.

HOW TO APPLY THE PATCH
1. Before replacing the db2java.zip files in your sqllib/java 
   and sqllib/java12 directories rename these files. Rename the
   jdbc20.exe file as well.
2. Download the db2java.zip from SQLPJatch/java and jdbc20.exe
   from SQLJPatch/java12. Copy them to the correct directories 
   i.e. sqllib/java and sqllib/java12 respectively.
