[Performance Tuning] - Re: RMI per call overhead?
by caultonpos
Yes, direct IP. I found that caching everything to do with the bean lookup helped - got it down to 250ms so that was an improvement.
I have all the reference data cached with infrequent checks. Activity data I just check if it has changed. I was able to get the application reasonable over the internet. If I could batch a number of calls together that would certainly help in some cases though there are not that many opportunities.
Managing caches to prevent stale data is tough but I think I can do it.
It still doesnt make sense to me that there is that much overhead on a single RMI call over the internet. Does one Boolean call with no parameters pass a lot of additional content? But regardless if I can ftp at 100's of KB per second...
There must be something still to be tuned there, doesn't quite add up.

[JBoss jBPM] - Re: JBPM 3.2.1 web app?does not display deployed process
by jdickins
Hey all,
I am still getting the same error I started out with and am still unable to get my process definition to display on the jBPM web app.
Here are the steps I've taken thus far
1) I downloaded a new copy of Eclipse (Version: 3.2.2)
2) Downloaded jbpm runtime and suite (both 3.2.1).
3) Setting the runtime (Window-> Preferences-> Jbpm-> JBPM Runtime) to ?JBoss Jbpm Runtime 3.2.1?
4) Deleting my old versions of jbpm (starter kit 3.1.3 and 3.2.1) and Eclipse (3.3)
5) Using the advice in this post
http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3963971#3963971
5 cont.) to deal w/ the message I received upon startup with my new eclipse "An internal error occurred during: "Initializing Java tooling"". The stack trace I had was exactly the same as the one in the forum post above. Is there a Jira Issue for this? I searched the Jira site using max.andersen(a)jboss.com?s name and the date range I thought it might have been reported in and found nothing. Not a big deal as the forum post covers how to fix the problem pretty extensively.
6) Resetting the workspace (cleared up the other errors I had been experiencing)
7) Importing my project from my previous workspace
8) Attempted to deploy my project.
I attempted to deploy the processdefinition from the web app and received the error:
anonymous wrote :
| Error deploying process: An exception of type "org.jbpm.jpdl.JpdlException" was thrown. The message is: [[ERROR] no processdefinition.xml inside process archive]
Thanks to msandoz, I tried deploying locally in Eclipse. When I deployed the process archive from the web app it produced the an error (but was still more constructive than the processdefinition error ;-D). Here is the error it produced:
anonymous wrote : Error deploying process: An exception of type "org.jbpm.jpdl.JpdlException" was thrown. The message is: [[ERROR] couldn't parse process definition]
When I try to deploy from Eclipse's deployment tab I receive the error:
anonymous wrote : An exception happened during the deployment of the process. Reason: an unexpected exception caused the deployment to fail.
Here is the stack-trace:

In my current IDE version, other than changing my jbpm server preferences, I am not sure how to tell the IDE to deploy to jbpm-console instead of jbpm/deploy (which appears to be the first complain in the stack trace). This, however, is a side issue to the main issue that I still cannot view my process definition from the site localhost:8080/jbpm-console.
It is because of this that I attempted to deploy from the web app, but as I previously stated, received the same error as before.
If anyone has any thoughts about how to get my locally saved process archive to display on the Web App I would be most grateful. Thanks again to everyone who has spent time thinking about this thread.
