Hi,

Anybody knows about below exception. I am not able to figure out why this exception occurred.

Note: This exception occurred only once for some period. After some time it worked for same set of data.

Caused by:
java.lang.NullPointerException
at oracle.jdbc.driver.OraclePreparedStatement.processCompletedBindRow(OraclePreparedStatement.java:1768)

Got some Idea..

In the context of a very slow LAN with very little bandwidth left, it is possible that we get java.lang.NullPointerException on OraclePreparedStatement.processCompletedBindRow.
