RE: Problem with RPG/Java call

Because java pgms resides on IFS, and IFS does not support the concept
of adopted authority, when calling java from RPG you need to make sure
that the user runs RPG has authority over the IFS folders where the java
jars are located. 
At least this was the reason I got a similar exception. My workaround
was to switch the user ID to a user ID that has proper autorities before
calling java, then switch it back to the current user when it is done. 
Hope this helps.

Subject: Problem with RPG/Java call

I have been struggling with this issue for quite some time now.  I am
making a call from an RPG program to a Java program.  The RPG program
sets up the environment (classpath, etc), sets the parameters, calls the
Java program and retrieves the parameters from the Java program.  The
Java program connects to a secure server on the internet and retrieves
data from a web site.
 
This process was working until the target site changed their SSL
certificate.  The certificate they changed to was malformed and would
error when using the JDK 1.3.  I have since changed to 1.4.1.  
 
When I run the RPG program using a profile with *ALLOBJ authority, the
process works well.  When I run the program with a user profile with
lesser authorities, the program errors in the execution of the Java with
"weird" errors such as:
 
Cause . . . . . :   RPG procedure CRD002R in program PRODPGM/CRD002R
received
  Java exception "java.lang.NoSuchMethodError: append

  (Ljava/lang/StringBuffer;)Ljava/lang/StringBuffer;" when calling
method     
  "<init>" with signature "()V" in class "com.shipley.ssl.CRD001J".

 
I have compiled the RPG program using adopted authority with a user
profile that works.
 
Any suggestions?
