Java stored procedure problem(oracle db)

Question

HI,
we have a java stored procedure with the following definition, and that works as we want it to:
CREATE OR REPLACE FUNCTION processBulletin(in_varchar VARCHAR2) RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'JavaParser.Bufr_Ingest.processBulletin(java.lang.String) return java.lang.String';
And the Java portion:
public static String processBulletin(String in_bull)
... do something with in_bull
The problem is that we've recently discovered that the 32767 size restiriction on the input parameter varchar2 is too small. I don't want to rewrite the entire Java procedure. I figured the simplest (or at least temporary)solution would be to have the Java procedure accept a CLOB, convert that clob to a string and continue as it would. I was hoping someone might be able to tell me if the following would be possible:
CREATE OR REPLACE FUNCTION processBulletin(in_clob CLOB) RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'JavaParser.Bufr_Ingest.processBulletin(oracle.sql.CLOB) return java.lang.String';
And the Java portion:
public static String processBulletin(oracle.sql.CLOB in_clob)
String in_bull = clob_in.getSubString(1, (int)clob_in.length());
... do something with in_bull
Thanks

I don't know about Java stored procedures, but in JDBC you usually use streams to work with CLOBS. Here's Oracle JDBC Developers Guide, Working with LOBs
