Click here to download the BPEL Suite
“Hello World/ErpSchools” Tutorial in BPEL
Click “close” to close the tip
Right click on the Application and select “New Application”
Select “Integration Tier” and then “BPEL” in the categories and then in Items select “BPEL Process Project”
Click OK. Now “BPEL Project Creation Wizard” will open as shown below
Enter the name: erpschools_process
Name Space: Leave it as default
Template: Synchronous BPEL Process
Click Next
Leave the default values and click Finish
Now you will see a screen like this
Now on the right side tab you can see the “Assign” icon in the component pallet
Select it and drag into the diagram. When you drag you will see green circles representing where you can drop the Assign component. I will drop between “Receive Input” and “Reply output” as shown below
Double click on the “Assign_1″ icon in the diagram
You will see the below screen
In “General” tab you can change the Name or you can leave the default
Next Click on “Copy Operation”

Expression Builder screen will pop up as shown
Now in the right side tab in “Advanced Functions” select “String Functions” as shown below
Now double click on “Concat” and it should copy the concat function to expression tab on the top as shown
Now manually enter the parameters for that concat() function as shown
Enter the welcome message as shown and place the cursor immediately after the comma
In the BPEL Variables select the Clinet:Input variable and double click it. It will automatically insert the path on the top
Click OK.
We are done with from expression now
In the right side tab select the output variable as show below
To see the detailed information for that input variable select “Show Detailed Node Information” check box in the bottom
Now click OK
Click Apply and then OK
Now coding part is done. We have to deploy this process.
Prepare to deploy the process.
Start the SOA Suite
Programs >> BPEL >> Start SOA Suite
Once it is started you will see a screen like this
Now go back to JDeveloper
In the left panel you can see the “Connections Navigator” click on that
Now select “Application Server” and right click to select “New Application Server Connection”
You get to see the below screen
Leave the Connection Name as it is and click “Authentication” tab and
Enter the username/password
By default it is oc4jadmin/welcome1
Go to next tab “Connection” and enter as follows.
Now go to Test tab and click “Test Connection”. If you get “Success” message you are good to move forward if not go back and check the ports and hostname e.t.c
Click OK
If you expand the “application Server” in the left panel you will see the directory structure as follows
Integration Server Connection
Now right click on “Integration Server” folder as shown and select “New Integration Server Connection”
You can leave the Connection Name as it is and click on next tab “Connection”
Now select the Application Server that we created in the previous step.
Click on “Test Connection” tab
Click “Test Connection” button
Now you should see the below text
Application Server: OK
BPEL Process Manager Server: OK
ESB Server: OK
If all the three servers are OK you are good to deploy the process.
If you expand the Integration Server folder you will see the directory structure as show below
Now preparation to deploy the process is done.
Go back to Applications Navigator in the Left Panel
Select the process , right click , select deploy , Server Connections >> Connection that you created previously
You get a message in the bottom of the screen saying success or fail. If success everything is good if not you can deploy through another method.
It can fail for many reasons it depends on your browser settings, windows settings, ports, permissions e.t.c
Deploy and create BPEL Suitcase
Go to Developer Prompt
Click Programs >> BPEL >> Oracle BPEL Process Manager >> Developer Prompt
It will open a command prompt and will take you to “samples” directory
Cd ..
Cd bin
Now type
Bpelc.bat “path of your bpel.xml file in your application folder”
In the first step while creating the new application we have the path “C:product10.1.3.1OracleAS_2bpelsamplesPrudhviApplication1″
So navigate to that folder and then click the process folder here it will be erpschools_process and then to bpel directory
Final path will be
“C:product10.1.3.1OracleAS_2bpelsamplesPrudhviApplication1erpschools_processbpelbpel.xml”
Execute the below command in the developer prompt(in cmd prompt)
Bpel.bat C:product10.1.3.1OracleAS_2bpelsamplesPrudhviApplication1erpschools_processbpelbpel.xml
You should see the successful message as shown above.
It will also tell you where the BPEL Suitcase is created and the name of the suitcase file. Usually the name suitcase will be appended with date and its extension is .jar
After you create the BPEL Suitcase you have to manually deploy it.
In the browser type the below url
Default username and password will be
username: oc4jadmin
password: welcome1
Once you login you will see the below screen
Click on “BPEL Domains” tab on the top
Now click on “default” BPEL Domain
It will open a new window as shown below
In the Left panel you can see all the BPEL processes you have deployed till now.
To deploy our new process click on “BPEL Processes” tab on the top
Click on “Deploy New Process” in Related Tasks
Click Browse and select the BPEL Suitcase that we created using bplec.bat previously
Now click “Deploy” button.
If you get a successful message as shown below your BPEL process is deployed successfully.
Click Done.
Monitor BPEL Process
Now I can see my BPEL process which is erpschools_process in the BPEL Processes list
Now test your process.
Go back to “Dashboard” tab on the top
The last process “erpschools_process” is the process that we deployed just now. Click on it
In the payload >> input
Enter some message and click “Post XML Message”
That is the xml message you expect to come.
Click visual flow button to see the how diagram how the data is flowing
This is exactly what you see in JDeveloper when you built it.
Click Audit tab
Here you can see what are all the activities that you are performing in your process.
In this process we are receiving the input and copying input to output variable and then replying the output.
If you click the “View Raw XML”
You can see the XML code in new window
Here you can see the xml code for both input variable and also output variable
Now click on “Instances” tab on the top
It will show all the instances that the process has gone through.
Let me explain this using an example. Suppose you have a BPEL process names “Load Sales Orders BPEL Process” to load “Sales orders” in order management. If you are importing one by one sales order through this process then you will have one separate instance for every sales order. If you get error while importing sales order#3 that particular instance will show that error.
Finally click on the tab “Activities” on the top
Here you can see all the activities that are performed for all the processes. Instance id is unique for each process. It is similar to “item key” in workflow.
