Lomboz ObjectWeb

Lomboz is a free J2EE development environment built on Eclipse.  Home page is http://lomboz.ow2.org/. The reason why i am trying it is because it provides a compact environment for bpel development by providing tomcat + ode easily. (how i prepared my own environemnt manually is here: http://hilaltarakci.blogspot.com/2009/04/eclipse-bpel-designer-apache-ode.html)

( how eclipse bpel desginer could open the bpel file without its extension bpelex file? btw, bpelex is created when i changed the file :) )

jbpm bpel - first steps

i am looking for someway to deploy my bpel processes on jboss app server. i do not want to use jpdl which is not a standart, so i stuck to bpel.

This seems to be a solution: http://www.jboss.org/jbossjbpm/bpel/
As such, it can execute processes authored with the Eclipse BPEL designer or any other editor that produces standard BPEL documents.

Bpel designers generally generate some extra xml and so, it may be possible that you can not open your bpel process designed with Activos Designer with Eclipse Bpel Designer,or vice versa. (correct if i am wrong:)) However, OpenESB allows me to produce clean, standart bpel file without adding any extra xml. (When you design a process with Open Esb (Netbeans) Bpel designer, you will notice that the location for the elements are fixed in the GUI, you can not put anything you like at anywhere in the designer, you have to choose from some predefined locations.. i think that is why Netbeans designer's bpel is so clean:) since it does not require to keep the location info, no extensions to standard bpel is needed..) Therefore, the above sentence about jbpm bpel (in italic) is important to me.. This means, i may develop my bpel process with OpenEsb designer and deploy to jbpm bpel.. This post is to note down that experience..

The steps are as follows:

  • in order to make use of the examples coming with the jbpm bpel package, the following must be already installed:
- ant
- jboss app server (4.x.x is required according to https://jira.jboss.org/jira/secure/attachment/12311453/jbpm.bpel.guide.pdf)
- java 1.5 (i do not know why, but i could not make jwsdp accept jdk 6, during installation, that is why i need jdk 1.5, more specifically jdk1.5.0_19 is ok)
- java web services developer pack (the examples use wscompile etc. ant tasks from here, so using metro instead is expensive, i gave up on the way half.. ) jwsdp is needed just for running the given examples, not part of the actual solution. in actual case, metro web service stack will be used instead..

this package includes many bpel samples. however, in order to run these samples properly, the following modifications may be needed:

  • In jbpm-bpel-1.1.1/examples/common/build.properties file, modify the following properties accordingly:

jboss.version=4.2.3.GA (i am using this already, but any 4.x.x is said to be ok)
jboss.home=${software.installation.dir}/jboss-${jboss.version} (if different)
jwsdp.home=${software.installation.dir}/jwsdp-1.6
javac.source=1.4 (modify as 1.5)
javac.target=1.4 (modify as 1.5)

  • start jboss, (starting from port 8080 may be required, not sure. if something goes wrong, check that..)
  • execute command ant inside jbpm-bpel-1.1.1/examples, it should execute with success..
  • lets see if wsdl s are available:
http://127.0.0.1:8080/account/accountSystem?wsdl
http://127.0.0.1:8080/invoice/invoiceService?wsdl
http://127.0.0.1:8080/scheduling/schedulingProcess?wsdl
http://127.0.0.1:8080/shipping/shippingService?wsdl
http://127.0.0.1:8080/task/taskManager?wsdl
http://127.0.0.1:8080/ticket/ticketIssuer?wsdl
http://127.0.0.1:8080/translator/document?wsdl
http://127.0.0.1:8080/translator/text?wsdl

i got the addresses for the wsdl s from ${JBOSS_HOME}/server/default/data/wsdl

now it is time to dive into https://jira.jboss.org/jira/secure/attachment/12311453/jbpm.bpel.guide.pdf deeper, but it can wait :)
i do not want to ruin my sunday afternoon with that :)

Edit on 6/7/2009, 12.04: Sorry, i have forgotten to deploy jbpm-bpel itself on jboss.. So, at anytime you like, execute command ant deploy.ear inside /jbpm-bpel/jbpm-bpel-1.1.1/deploy and jbpm-bpel will be deployed on jboss. try to see jbpm bpel console from http://localhost:8080/jbpm-bpel/

Edit on 7/7/2009, 10.55: Yeah, OpenESB designer produces standard bpel files. However, unfortunately this does not mean that it could open every standard bpel file in its designer..

Eclipse Bpel Designer & Apache ODE

Hello everybody! In this record, I give some basic info about Apache ODE and how to integrate ODE with Eclipse through Eclipse Bpel plugin. Since Eclipse Bpel plugin have not published ODE runtime integration yet, this is not straightforward at this moment. Besides, current Eclipse Bpel does not support Eclipse Ganymede, but I use Ganymede in the following case..
Lets begin..

Deploying ODE to tomcat (5.0.28):
Download .war distribution of ODE 1.2 from http://www.apache.org/dyn/closer.cgi/ode/apache-ode-war-1.2.zip . Extract the file. Copy ode.war to $CATALINA_HOME/webapps. Start tomcat. Open http://localhost:8080/ode
BağlantıDeploying processes to ODE: Put the process folders under $CATALINA_HOME/webapps/ode/WEB-INF/processes manually for manual deployment.

ODE Client: As I know, there is no interface for ODE in which I can see deployed processes except axis2 interface, active processes etc. like ActiveBpel. However, ODE provides the api for this. For instance, this is my little ODE Client to see deployed processes:
-----------------------------
package ode.client;

import org.apache.axiom.om.OMElement;
import org.apache.axis2.AxisFault;
import org.apache.ode.axis2.service.ServiceClientUtil;

public class ODEClient {
OMElement listAllProcesses() throws AxisFault {
ServiceClientUtil client = new ServiceClientUtil();
OMElement root = client.buildMessage("listAllProcesses", new String[] {}, new String[] {});
OMElement result = client.send( root, "http://localhost:8080/ode/processes/ProcessManagement");

return result;
}

public static void main(String[] args) {
ODEClient client = new ODEClient();
try {
client.listAllProcesses();
} catch (AxisFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
-----------------------------

Eclipse & ODE runtime integration: This is not published yet. (
http://www.nabble.com/Setup-apache-ODE-runtime-td17848560.html)
However, by following the steps in
http://people.apache.org/~vanto/HelloWorld-BPELDesignerAndODE.pdf , it is possible by getting the latest version for the plugin!
Unfortunately, Eclipse Bpel Designer plugin is not available for Ganymede. But, since I get the latest code for the plugin, I can use Eclipse-Ganymede-Rcp instead of Europa.

Different from HelloWorld-BPELDesignerAndODE document, I did the following:
  • Use eclipse-ganymede-rcp, instead of eclipse-europa-rcp. Otherwise, since the latest code is for ganymede, there will be errors due to version differences.
  • Skip part 2.1 if Apache ODE is already installed.
  • Skip steps 1 to 8 in part 2.2 since BPEL designer is not available for Ganymede in the update site.
  • In step 12 in part 2.2.1, check out all bpel projects under org.eclipse.bpel/plugins.
  • Some of the checked out projects were erronous due to lack of some org.eclipse.wst component. So, installed all plugins starting with WST under ganymede update site (uncategorized).
  • Some projects were erronous due to lack of org.eclipse.jst.. Install all plugins starting with JST under ganymede update site (uncategorized).
  • Delete project org.eclipse.bpel.xpath10.junit since other projects do not depend on it and it mostly consists of unit test.
Currently, all the projects must be error-free :) Continue with step 16 in part 2.2.2.
  • For step 16, Open Run Dialog is Europa is analogous to Run Configurations in Ganymede.
It seems that it supports ODE 1.0, but it did also worked with ODE 1.2 :)

I had problem in viewing http://localhost:8080/ode, however wsdl was ok in http://localhost:8080/ode/processes/HelloWorld?wsdl, so ı didn't care :)

Note on 4/5/9 : I could not view ode since AXIS2_HOME is not defined. When I added this environment variable, it is OK :)

ActiveBpel & ODE Comparison:
http://www.mail-archive.com/ode-dev@incubator.apache.org/msg00825.html
Besides, ODE package structure is very simpler than ActiveBpel.

Some documentation:
