You can change ports if you want. If the default ports are not used by any other application, you can keep them as they are. After setting the ports click Next.

The WSO2 CAR Deploy plug-in for Maven allows you to generate the CAR file for a C-App and then deploy it (or undeploy it) on multiple local and remote Carbon servers, including StratosLivePaas. To use this plug-in, you add it to the pom.xml file for your C-App and then use the mvn clean deploy command to generate and deploy the CAR. See the Deploying a CAR File with the Maven Plug-In sample for a walk-though of how to deploy a CAR file containing ESB artifacts.

2. Click the the Source tab  tab and navigate to the the maven-car-deploy-plugin under  under <build> -> > <plugins>.
3. Modify the the maven-car-deploy-plugin properties  properties as follows:
   
   1. Under Under <carbonServers>, create one one <CarbonServer> for  for each Carbon server where you want to deploy the CAR file.
   2. Specify the following properties for each Carbon server:
      
      • If you are using a custom certificate with your Carbon server, import the public key of the custom certificate to your trust store, and then set
   the
   1. • the <trustStorePath>, <trustStorePassword>,
   and
   1. • and <trustStoreType>
   properties
   1. •  properties to the location, password, and type of your trust store.
      • Set
   the

   and
   1. • and <password>
   properties
   1. •  properties to the URL (such as https://localhost:9443), user name, and password for the Carbon server.
      • In
   the
   1. • the <operation>
   element
   1. •  element, specify whether to deploy or undeploy the CAR file for this Carbon server.
        
   In the <properties> section at the end of the POM file, do the following:

   1. • To deploy: <operation>deploy</operation>

        To undeploy: <operation>undeploy</operation>
 

      • Add the following line to the properties to ensure that the CAR file will be deployed:

        Code Block
        language xml
        <maven.car.deploy.skip>false</maven.car.deploy.skip>

        If you want to deploy the CAR file to a remote Maven repository in addition to the Carbon servers, add the following line to the properties:

        Code Block
        language xml
        <maven.deploy.skip>false</maven.deploy.

      • skip>

      Info
      You will be able to override both of these settings when you run the Maven command.

4. Save the file. You are now ready to generate and deploy the CAR file for this C-App.

Then create a Composite Application Project to group it.Image Removed

Now add a WSO2 Application Server instance to your Eclipse workspace. Steps to add a Carbon Server is described in the Deploy a C-App to a running Server inside Eclipse section. After adding the server, start the server in the debug mode.
