Hi
I try to get a BLOB from an oracle database and to save it to a file.
>From a small test program everything works fine. When I copy the code
into a servlet I get a strange error from the database at the moment
when I try to read the first byte on the InputStream:
java.io.IOException: ORA-01013: user requested cancel of current
operation

The JDBC connection works fine for Varchar and other "normal" data from
the database.
I saw in the archive that somebody had a similar problem, but I couldn't
find any answer to the problem.
I use Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_01)
and Oracle8i Enterprise Edition Release 8.1.5.0.0. with the thin
driver(classes111.zip) from oracle.
I use Tomcat 3.1.
Does anybody have an idea about this problem?
