Passing Opaque Objects from Oracle to Java

Question

Hi all
I am trying to write a stored procedure that needs to be called from different triggers. Each triggers needs to pass a different set of data to the stored procedure. Now the problem is that i need to pack the different set of data into one opaque object type that i can pass onto java. Is there any way of doing this. I am using Oracle 9i running on Linux 2.4.9. I tried using the Object datatype in Oracle 9i. But am not able to pass a object datatype to java directly.

Didn't know that. Guess the way this API handles the struct is it puts it on the heap, since this idea (with passing a 32-bit var back and forth with a memory location) worked.
My next problem - I can't figure out a way to destroy a jstring: whenever I do an env->GetStringUTF((char*)charBuff), it seems to simply copy the bytes from the buffer
into the same String object up the length of the buff (so I get the extra bytes from the previous String if it was longer at the end).
Here's how it works: I have a loop in C code that parses tags inside a file, then depending on what tag it is, I create a new jobject and call a Java method to do stuff
to that object. As one of the parameters in the constructor I pass in a String that I create (as you can see above) from a character array, however I am getting
massive artifacts when I print out that String inside the Java method.
Thoughts? :(
