Installing BPEL designer and Apache ODE on Eclipse > v3.6.2

This tutorial presents you how to install the BPEL designer and Apache Orchestration Director Engine (ODE) on Eclipse 3.6.2 (Helios or older) for simulating BPEL processes.

1. Suppose that you have already downloaded and installed your Eclipse > v3.6.2 (Helios,or Indigo), version for Java EE Developers and JDK (version > 1.5).
2. Open the Eclipse, go to the menu Help→Install New SoftWare.
3. Click on the button Add and define a new Eclipe update site with the location:
   http://download.eclipse.org/bpel/site/1.0.4
   
4. Now you have the update-site of BPEL available on the eclipse. Select the check box to Eclipse BPEL Designer and click on the button Next.
   
   
   
5. Follow the installation windows, you will now have your BPEL installed on Eclipse. Note that: the BPEL dependencies(WTP, EMF, GEF, JEM) should be installed before the BPEL designer. Fortunately, with Eclipse Helios for JavaEE, you have all.
6. After finishing the installation, restart it.
7. To verify the installation was successful, after the restart, click on File→New→Other, you will see the BPEL 2.0 is on the list.
   
   
   

The BPEL designer is now ready to use. However, to run the BPEL process, you should have the server's environment. Now, we are going to install the Apache ODE for the BPEL deployment.

1. Download and extract the latest ODE from the Apache web site. The current stable version is the ODE 1.3.5.
2. Inside the “apache-ode-war-1.3.5” folder, you will see an “ode.war” file. Deploy this file on your Tomcat server.
3. The simple way to do this is extracting the “ode.war” file to get the ode folder.
4. Copy this ode folder to your TOMCAT_DIR/webapps directory.
5. That's all.

Now, you have finished the installation steps. Now, you are going to set up the ODE server on Eclipse to run the BPEL application.

1. Show the “Servers” view by selecting the menu Windows→Show View→Servers.
2. Right click on the empty space of the “Servers” view, select New→Server.
3. Leave the server host name as localhost and select the server type as the Apache→Ode v1.x Server. Rename the server's name if you want. In my installation, I keep the default name. Then click on the button Next.
   
   
   
4. Select the JRE as the Default JRE which was integrated in the Eclipse. Set the path to the ODE's home directory and the Tomcat directory. Then, set the Tomcat's port as the port in its configuration file. The default port is 8080.
   
   
   
   Note that: the ODE Runtime configuration above can also be added or editted using the menu Windows→Preferences→Server→Runtime Environments.
   
   
   
5. Click Finish. You now have the ODE server which is ready to run on the Eclipse. You can see this server on the Server View.
6. Now, you should test the server's configuration by right click on the ODE server entry and select Start. Or you can click on the Start button on the Server View. If the server is sucessfully started, you will see the status like this.
   
   
   
7. If you are using Tomcat v.6 or v.7, you probably get the error
   
   

   Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
     at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:54)
   Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory

   Could not find the main class: org.apache.catalina.startup.Bootstrap. Program will exit.

8. This error occurs maybe because it misses the tomcat-juli.jar in the Launch environment.
9. To fix this, double click on the installed Ode v1.x Server in the Server View to see the configuration.
   
   
   
10. Click on Open launch configuration → Classpath tab → Add External JARs → [your TOMCAT_DIR]\bin\tomcat-juli.jar. Then Ok.
    
    
    
11. Now try to start your ODE server in the Server View.
12. Terminate the server by clicking on the Stop button or right click on the server and select Stop. Every thing is ready now for the first BPEL program.

1. Change the ODE Server's port to another number (such as 9090) using the “Note” in the step 4, part “Setting up the ODE server on Eclipse”. Then, can you start/stop the ODE server?
2. Now, you change the server's connector port in the file TOMCAT_DIR\conf\server.xml to the ODE Server's port number (9090 as above). Save the file. Can you start/stop the server?
