Developers help / Re: Logic for execution in the jppf example
« Last post by lolo on July 09, 2020, 07:50:45 AM »
Hello,

Sorry for the late reply.
Yes, JPPF distributes the code of the tasks automatically, using its distributed classloader.
It is not the only way to transport the code along with tasks and jobs, but it is by far the simplest and most seamless for ther users.

Sincerely,
-Laurent

Hi all,

I was watching the code in the Template and I found that TemplateJPPFTask is called from TemplateApplicationRunner... it means that I just have to install the node in the pc's which will collaborate to proccess the Job and JPPF will distribute the code of the task? Or should I install and run the TemplateJPPFTask in the nodes?

Thanks all.

Hi 'Lolo',

I had read the link page you gave me. For me this is clear but what I can't understand is the way that the example program works. In this link https://www.jppf.org/doc/6.2/index.php?title=A_first_taste_of_JPPF I follow the instructions (after the 5 step):

1. Execute the Jppf driver (using the .bat)
2. Execute the jppf client (using the .bat)
3. Execute the jppf template -> But the .bat file saids:

call %JAVA_PATH% -cp config;classes;lib/* -Xmx64m -Dlog4j.configuration=log4j.properties -Djppf.config=jppf.properties -Djava.util.logging.config.file=config/logging.properties org.jppf.application.template.TemplateApplicationRunner

It is calling org.jppf.application.template.TemplateApplicationRunner which is the template for the client genereting a Job. Nobody is calling the TemplateJPPFTask... there is when I can't proccess it!.

Thanks

Hello,

If you take a look at the JPPF Overview > Work distribution section of the documentation, this should give you a good idea of the flow of jobs/tasks in a JPPF grid.

TemplateJPPFTask is a task that is part of a job. It is created on the client side (i.e. its constructor is invoked in the template application) and executed on a remote node (i.e. its run() method is invoked by a node). Once executed, a task is sent back, in its executed state, to the client that submitted the job it belongs to.

I hope this clarifiies,
-Laurent

Hi all,

I'm new with JPPF and I'm trying to implement my first code using the example of 'A first taste of JPPF' but althought the execution of the .bat's works fine, I can't unterstand how. I executed the .bat for the driver, node and the .bat for the application template. It runs fine and do what the page said it should do but I don't know  how it do that... that .bat runs 'org.jppf.application.template.TemplateApplicationRunner' (As I see in the .bat file)... what I unknow is when the TemplateJPPFTask.java is called to be waiting for orders to run. As I can't understand that, I couldn't implement my first code yet.

Could some one explain me that? Thanks a lot.

Regards,

Troubleshooting / Invalid TLS padding data
« Last post by wimvc on April 06, 2020, 09:43:54 PM »
Hi,

I've been running JPPF for quite a while succesfully with my application. Today, I decided to use the SSL option for connecting to my driver (nodes still connect over a regular connection). It seems to work initially, until at some point (when results return)  I get the error "Invalid TLS padding data"  with some tracktrace (unfortunately I missed logging the entire stack trace). After that, the connection is lost and then re-established.

Is there anyone who can help me with this, what could be causing this?

Developers help / JPPF 6.2 support for > Java 8
« Last post by wimvc on March 17, 2020, 09:32:27 PM »
Hi,

I'm currently on Java 8 (still ... ) for my JPPF project, but I was wondering if the current JPPF release (6.2 at time of writing) or earlier support Java 8+ - specifically Project Jigsaw, ie. the module system.  If so,  are there certain things/pitfalls that we need to take into account when one would use eg. Java 11 (I consider this a nice LTS release) together with JPPF?

Best,
Wim.
