RE: Prototyping Java

["Bruce Odum" <bodum@xxxxxxxxxxxx>]

Thank you for the lead. I now have the email java app working with ILE
RPG. We can send up to 32 attachments and add(don't know the limit yet)
as many CC's To's and reply to's as needed. Now to wrap it all into an
API and we will be good to go

Bruce,

While it might be easy to prototype your supplied java interface, it
wouldn't provide you the necessary background for integrating your
RPG apps with Java, so....
 
One of the best places to start is the ILE RPG Programmers Guide.
Chapter 11 of the V5R1 version, entitled "RPG and the eBusiness World",
contains numerous code snippets demonstrating prototyped calls to
java classes.  Additionally, there is an execllent table on page 159
providing a "map" between RPG and Java data types.  As you are
interested
in passing arrays to/from Java, note #4 might be of interest to you,
as will the paragraph that reads "When calling a method, the compiler
will accept arrays as parameters only if the parameter is prototyped
using the DIM keyword". The following thread also provides some valuable
info regarding java arrays & RPG:

http://archive.midrange.com/rpg400-l/200404/threads.html#00020   

Also, while chapter 11 does contain considerable information and
insight into calling java from RPG, the presentation and contents can
be extremely confusing for non-java people.  So while I refer you to
this chapter as a starting point, it is just that.  Beyond that, there
are several posts on this forum demonstrating and expanding on some
of the details in chapter 11.  I would recommend scanning the RPG400
list using the keyword JAVA. 

Lastly, when you're done pounding the wall with your head, as
integrating
RPG & java can often lead to, you can always post some of your questions
or code here.

Hope this helps....

We have a java person here that rewrote the javamail utility and added
several features.  It uses arrays to pass data and no one here has ever
had to fig out how to prototype a java program. How do you even begin
this process. I have a sample of the java call below.

public USXMessage(javax.mail.internet.InternetAddress[] from,
                  javax.mail.internet.InternetAddress[] to,
                  javax.mail.internet.InternetAddress[] cc,
                  javax.mail.internet.InternetAddress[] replyTo,
                  java.lang.String subject,
                  java.lang.String text,
                  java.lang.String[] attachments)Creates an email
message using the given criteria
Parameters:
from - - Array of values to be used for the from field of the email
message
to - - Array of email address for the recipient of the email message
cc - - Array of email address for the email message to be carbon copied
to
replyTo - - Array of email address to be used when replying to the sent
email
subject - - Value to be used for the subject of the email message
text - - Text message
attachments - - Array of Files to be attached to the email message
