Java setBinaryStream

In writing files to a Sybase table, we are using PreparedStatement.setBinaryStream.  There are different  versions of this method, and we want to use the one where we can just pass an InputStream, along with the colIndex.

But when we use the setBinaryStream(int, InputStream) method, there's an AbstractMethodError.  Looking into this, it may be because "our JDBC driver implements an older version of the JDBC API than the one included in our JRE."  But we are using jconn4.jar and Java 1.6.0, which seem to be recent enough.  We are running the application in WebSphere 8.5.0.2.

Does anyone know what might be going on here?

The setBinaryStream(int, InputStream) is introduced in java 6. And, you identified correctly it is compatibility issue. Since jconn4.jar is older one, it may not be compatible with java 6. Check which version of JDBC driver is used and it is compatible with Java 6.

Solution to upgrade your JDBC driver as well as other APIs if it is not compatible with Java 6.

I'm not sure how to check the version of JDBC driver.   I don't have %JDBC_HOME% locally, and don't see $JDBC_HOME on the application server.

OK.
c:\svn\java\main\WebContent\WEB-INF\lib>java -jar jconn4.jar
jConnect (TM) for JDBC(TM)/7.07 ESD #5 (Build 26792)/P/EBF20686/JDK 1.6.0/jdbcmain/OPT/Mon Oct 15 11:36:14 PDT 2012

so this seems to be 7.07 which should be fine.  I'm thinking that jconn4.jar is fairly recent.
