Ronri Kobo, Inc. releases JExternal 6.0.1

JExternal 6.0.1 is now available for download.

JExternal is a 4D plug-in to execute Java methods from within 4D. JExternal enables you to use many useful Java libraries in 4D. In this new version, JDBC_ORACLE_CURSOR is added as a JDBC constant in order to call Oracle stored procedures using Ref Cursor.

If you use JEX_JDBCDemo_601, which is a demo of JExternal 6.0.1, you can call Oracle stored procedures using Ref Cursor and get cursors as the result. In JEX_JDBCDemo_601, an example method EXAMPLE_CODE_17 was added to explain how to call Oracle stored procedures using Ref Cursor and get the results. The Java source code of the class library JDBCDemo_200.jar used in this demo is open. Oracle 10g and 11g, and JDBC driver ojdbc6.jar were used for the test.
