Calling Java classes directly from Powerbuilder

[crbr...@vac-acc.gc.ca]

Can I call a Java class directly from PowerBuilder? How would I do this?

Thanks
Craig

Not natively. However, you can create a COM wrapper and then use
ConnectToNewObject in PB.

An example of using the MS Java SDK to do this can be found at:

There is also a Sun way of achieving the packaging of java classes (or beans
to be exact) in OLE objects. Here is a web page I found:

I was motivated to get into Java-n-PB yesterday after responding to your
post. I downloaded the MS Java SDK last night and will probably get to it
sometime later today. I don't have Sun's on this computer (that one died a
few months ago) and I'm considering going the MS route for now. Check-out
the page Marcus suggested and let me know how it goes.

Marcus, have you tried the example as outlined in the web page? I did
everything by the book, but my VBScript fails creating the object.

Edward, I found out that the Java VM is an integral part of the Win2K
OS. That's why it wasn't in the SDK download. However, I still can't
run the MS example (java-0044.html) or the Sun example
(java-0045.html). In both cases, VBScript complains that it cannot
create the object.

Ho hum. I was actually excited to have the ability to call Java
rotuines from PB. In our application I have had need to pass certain
lengthy string manipulation to a DLL or something for speed. Since I
know Java now better than C, this seemed to be a good fit. Alas...

Actually, although it isn't part of the SDK download it is the link just
below it and the reason it is separate is because they are updated at
different times and for different reasons. So why download both every time
one is changed? The SDK is about 20MB... I'd hate to have to download that
without broadband each time the VM has an update. ;-)

http://www.microsoft.com/java/download.htm - is the download page for the MS
Technologies for Java Site

I did a little digging on the "not able to custom install" problem and found
the following on the Internet Explorer website;

"Windows 2000 Users: Internet Explorer Setup for Windows 2000 does not allow
you to customize the installation or use any advanced options in the Setup
program. This behavior occurs because of the new Windows File Protection
(WFP) feature in Windows 2000. "

I'm going to play with it right now and I'll get back to you.
