Hi. You have posted in the correct group because weblogic can have no effect on how Oracle and it's jdbc driver interact with LOBs. However, there is one parameter I can comment on. Which JDBC driver are you using? The Oracle jdbc drivers change at a faster rate than weblogic, so if you're using the version of the thin driver shipped with weblogic, you should download oracle's latest appropriate driver from them, and make sure it's ahead of the weblogic.jar in the -classpath argument constructed by the start-weblogic script. If your problem has a contributor in the driver, this may help.
