Calling a webservice inside JCaps 6

Assume we have a webservice. The first thing to do is to get a copy of the WSDL file of the service. Then inside Netbeans:

Select “File system” and click “Next >”. Locate the WSDL, and accept all default settings by clicking through the whole wizzard. The result:

Implementation

Next, create a new Collaboration Definition (JCD) inside the project. We want to initialize the JCD with a Queue message. So the input will be a JMS operation. For the output parameter look up the newly imported WSDL definition.

After creating the JCD, open it and look for the WSDL definition inside the mapping editor. Look for the PortType node. Rightclick the node :

Next an object browser window opens :

If the service needs input, we first have to fill all input objects, and after that call the invoke() like this (inside the code view):

Configuration

Create an environment inside the services tab of Netbeans with a logical host for catching message queue’s, and pointing to the right integration server. For calling the webservice we create an extra ‘SOAP / HTTP Webservice external system’.

Rightclick on the external system icon for the service, and click the ‘configuration’ menu:

It is also possible to store all above configuration data inside LDAP, and fill ldap://…. references inside the external engine configuration. After finishing the environment, create a connectivity map, drag and drop the JCD inside. Generate the mappings. Create a deployment profile and build the system.
