Compile synchronous J-Link application without restarting Creo

Dear PTC users,


maybe you have an idea how to solve my problem. I am going to develop a synchronous J-Link application in Creo Parametric (but version does not play a role in this case). I just want to compile my project, check if it works, i case of ocurring malfuctions recompile it, checking again, recompiling and so on. but i always have to restart Creo because the new compiled classes are not recognized while running Creo. I also tried to stop and/or unregister my plugin in aux application and restart/reregister it. i also tried to rename my plugin in creotk.dat.


Does anyone know a technique to avoid this?


In last time i always developed asynchronous apps. there you dont have this problem beacuse you can connect and disconnect to/from session each time.

Compile synchronous J-Link application without restarting Creo


Hi Mario -

I've been through this situation myself:

> malfuctions recompile it, checking again, recompiling and so on. but i
> always have to restart Creo because the new compiled classes are not

This is all perfectly reasonable, and I had the same problems. Here's
what you can do to resolve it:

1. Learn to attach the Java debugger to your JLink application.
Doing this has many benefits.

2. For simple changes, edit & recompile your JLink application
while the debugger is attached. Java will "hot swap" your
changes into the currently running code.

Hot swapping does not work if you add a new class or make "schema"
changes (new classes, methods or attributes) to your project. It
will really help you out with minor changes, though.

I wrote a conference presentation on this subject in 2010, but I can't
find that presentation now. I'll keep looking for it.

Set this in your config.pro:
jlink_java_command java -Xnoagent -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n

That will allow you to attach the debugger from your IDE. In Netbeans you find it under Debug > Attach debugger...
The dialog looks like this:

It works in a similar way in Eclipse.

RE: Compile synchronous J-Link application without restarting Creo

works perfectly fine with netbeans. thanks for your quick response. i also found your presentation. You called it "How to Debug ProENGINEER Applications in Any Language" from PTC World Event 2010

Mario -

I'm glad this worked for you:

> works perfectly fine with netbeans.

I haven't used NetBeans in a long time, but my guess is that NetBeans
actually TELLS you when it has performed a Java HotSwap update through
debugger. That's how I discovered HotSwap - by accident; when I re-
compiled while debugging in a commercial IDE named IntelliJ. As you
already stated, you can't stop and re-load JLink applications in Creo,
so hot-swap updates are incredibly helpful. I still think the concept
itself is incredible, too.

I receive no such notices from Eclipse. It seems to assume that I know
when the code was compiled and hot-swapped. Maybe I'm missing a plug-in.

> i also found your presentation. You called it "How to Debug ProENGINEER

I'm glad you did. I found it eventually, with help from Patrick Williams,
and also after searching through backup drives.

I still believe that the debugger is the most valuable function in any
IDE like NetBeans. I was once one of those programmers who insisted on
makefiles and hated Visual Studio. My attitude changed after the first
time I debugged code in Visual Studio 6 and saw it automatically display
my local variables.

Anybody who's writing Creo applications really should learn to use a
debugger, especially because it takes so long to set up and re-test
after a run-time failure. It will save you hours of tedious work.
