I am not very familiar with Java programming but I think you just need to do the following to be able to use a Java class from inside your DB2 proc.

You may define a function/proc which reference your external Java code.
I hope the following sample will be enough for you to define a reference to every needed of your Java functions.

CREATE PROCEDURE YourJavaFunc (IN aDouble DOUBLE, INOUT aInt INTEGER, OUT aChar20 CHAR(20))
DYNAMIC RESULT SETS 0
LANGUAGE JAVA
PARAMETER STYLE JAVA
NO DBINFO
FENCED
READS SQL DATA
PROGRAM TYPE SUB
EXTERNAL NAME 'YourClass.YourMethod'

Other kind of parameters are available:
"DYNAMIC RESULT SETS 1" if your Java class may returned data (There are some examples about this)
"MODIFIES SQL DATA" if your Java class makes modifications to data

Hope this helps.
