Environment Issue in Oracle 11g.

Question

I have a java stored procedure loaded into Oracle 11g that reads a CLOB type, and getting a null pointer exception in one oracle 11g environment and not in another. Following is the code snippet,
<code>StringBuffer str = new StringBuffer(); String strng; BufferedReader bufferRead = new BufferedReader(clb.getCharacterStream()); while ((strng=bufferRead .readLine())!=null) str.append(strng); </code>
I believe it has nothing todo with the code, because same code is not giving any error and working fine in the other. Following is the version of oracle 11g in both the environments
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production PL/SQL Release 11.1.0.7.0 - Production CORE 11.1.0.7.0 Production TNS for Linux: Version 11.1.0.7.0 - Production NLSRTL Version 11.1.0.7.0 - Production
can you please guide where else can i find the root cause of this issue. Is there a way to find the loaded java class versions on the database?

Answer 1

I'd suggest running it from SQLPlus, where all your System.out.println statements will show up and you won't need to bother the DBA for that output ... unless you have already done so or if you happen to be the DBA. From the snippet you provided the only thing that looks like it could be null is "clb".
