Setproperties on new ORDDOC gives ORA-6512?

Question

Hello,
I am attempting to convert the CLOBs in an existing table into ORDDOCs in a new table.
I seemed to be almost there. I allocated a new ORDDOC using INIT(), and used writeToSource() on the doc pointer to transfer the text (which I first converted to RAW). The application that accepts this now lists the new document, and displays the text contents.
I now need to set the size (and MIME type, even though the app seems to understand that it's a text document). I called setproperties after writeToSource, and get a set of ORA-6510/ORA-6512 errors. (Included below)
I'd really appreciate any advice!
Thanx and regards,
Arn.

Lawrence, thanx for your prompt reply.
I'll try restating my requirements and problems, and hopefully that will help.
We have an existing table containing text comments in CLOBs. I need to convert the contents of each CLOB into a separate new ORDDOC object in a new table. After this, I will also create a JSP screen that will allow new comments to be submitted, which will also be saved in the DB as ORDDOC objects.
The script I provided was my attempt at the conversion, using doc.writeToSource(). My first question is, is this the right way to go about converting CLOBs to ORDDOCs?
I have a screen that lists documents in the DB. This list includes the document size, which I determine using getContentLength(). For "real" documents - that is, sourced from external files and uploaded using the browser, such metadata is automatically captured. For my new document that is sourced from the CLOB, this information (content length, MIME type) is not automatically captured. I therefore need to set it somehow. I attempted to use setproperties, as althought setMimeType works, there is no setContentLength function.
After your reply, we looked into writing our own plugin, but could not glean from the documentation how to go about this - eg, where and how content length is set.
I hope you can provide further advice on this problem.
Thanx again, and regards,
Arn.
