Hi,
We have observed the exception *'JDBC activity timed out while updating the table -Table1"* in our logs in prod environment.
1)we verified the AWR report for that particular time and observed that one update statement was trying to update the table table1.
its a simple update statement as below
UPADTE TABLE1 SET COL1=VAL1,COL2=VAL2 WHERE ID1=VAL1 AND ID2=VAL2;
there is a PK index on ID2 column.
2)we also came to know that there were no locks on TABLE1 during this time.
can some one please let me know what could be the possible reason for this kind of exception?

Oracle does not know or care about the type or flavor of remote client (JDBC, OCI, ODBC, etc).
Oracle's default configuration contains no timeout.
I suspect a FireWall setting.
