How to run di basic example of WSO2 EI Business Process?

Question

I am absolutly new in WSO2 EI and I have the following doubt.

I am following this official tutorial to study the creation of a business process BPMN process ):

https://docs.wso2.com/display/EI600/Quick+Start+Guide

If you go in this tutorial the second tab is refered to the Business Process Management tutorial, then I continue following the business process BPMN process street.

I followed all the tutorial and I think that I have understand the key concept of this example but I have some doubts about how to run this example.

At the end of the tutorial it does:

To create the Business Archive File (.bar), do the following.

• On the Explorer, found in the upper left of your screen, navigate to Package Explorer .

• Right click on the package and select “Create deployment artifacts” .

• Navigate to the location of the source. You will find the .bar file inside the deployment folder.

So now I have my /HelloWorld/deployment/OrderApproval.bar file created.

But now what have I to do with this file?

I also have download the EI Server from here: /HelloWorld/deployment/OrderApproval.bar

Then I have configured it in my Eclipse Developer Studio EI setting it as a WSO2 server.

So my doubts are:

1. What exactly represent this OrderApproval.bar file? Is it a file representing a WSO2 EI executable project or what?

2. From what I have understand the previous example represents a work flow representing a BPMN process that implements a flow with some rules without that I need to write Java code (correct me if I am doing wrong assertion). But is it something executable or something that have to be integrated into some other application?

3. If it is an executable project what have I to do to run it and interact with it?

Answer 1

BPMN is process definition that can be run on BPS server. BPS server is part of WSO2 EI solution. You have to run it from [EI_HOME]/wso2/business-process/bin On Linux/Mac OS: sh wso2server.sh On Windows: wso2server.bat --run

Then, when it works correctly, open https : // [serverIP]:[port]/carbon/ and log into the EI-Business Process management console.

Next navigate to Home -> Manage -> Processes ->Add -> BPMN and upload your OrderApproval.bar file.

After uploading file, log into the BPMN-explorer at https : // [serverIP]:[port]/bpmn-explorer. On the "proecesses" tab you should see your process which can be run by action->start.
