Re: Java Stored Procedures -- JAVA400-L

Java *VERSION returns Version JVM V5R1M0 JDK 1.4.2.

Yes, I verified in LICPGM that 5722JV1 optino 4 is no longer installed.

Whether I call it via JDBC from another machine or JDBC using *LOCALHOST, 
I get the same results.  Here is the source:

Re: Java Stored Procedures






What  does “java *version” return? (or “java -version” in qshell).

You removed JDK 1.2. Can you verify it using “GO LICPGM” option 10?

What is “remotely called stored procedure”? is the code running remotely 
on another box?

Thanks.

Sorry!

I didn't mean to be so terse.  I'm using the following to retrieve the

JDK

version:
System.out.println(System.getProperty("java.version"));

Thanks for any help!

Re: Java Stored Procedures






How do you know you are getting JDK 1.2 from a remotely called stored 
Procedure?

Hello!

We are writing Java Stored Procedures on V5R1.  Our Java.Version always

returns 1.2.  However, when we run the same procedure interactively, we

get JDK 1.4.  We've tried messing with the SystemDefault.properties

both

for the system and in the user's directory, as well as QUSER, and even 
QSYS!

We removed JDK 1.2.  We still get JDK 1.2 from a remotely called stored

procedure.

Has anyone else experienced this?

Thanks!
