Debugging Custom Script in Integration Gateway

[midhun_vp]

Note: There is a known issue in this approach. Hence this will not work. I will update once it is fixed.

Some of the features that can be enabled using custom script in Integration Gateway (IGW) are: modify the requests and responses of an Odata request, handle delta token , multipart and composite WSDL support, and SOAP authentication. There are many examples in SCN on how to write custom script in Integration Gateway. In this blog I am explaining how to easily debug the script using IGW's eclipse based tooling.

From SMP SP06, debugging of custom script written in JavaScript is possible (Groovy supports in future). I have created a simple project using the WSDL http://www.webservicex.net/medicareSupplier.asmx?WSDL. High level details of the project is given below. Here I am not explaining how to create a project but I am explaining how to debug the script used in the project.

Odata Entity:

Custom Script written under function processRequestData

//Import statements    importPackage(com.sap.gateway.ip.core.customdev.logging);    importPackage(com.sap.gateway.ip.core.customdev.util);    importPackage(org.apache.olingo.odata2.api.uri);    importPackage(java.util);    importPackage(com.sap.gateway.core.ip.component.commons);    importPackage(com.sap.gateway.ip.core.customdev.api);    importPackage(org.apache.olingo.odata2.api.processor);    //Getting value from header    var context = message.getHeaders().get("odatacontext");    var City = context.getRequestHeaders().get("City").get(0);    var child = new LinkedHashMap();    child.put("key:City", City);    message.setBody(child);    return message;

How to start debugging ?

• Open prop.ini file of SMP server (C:\SAP\MobilePlatform3\Server)  and add the property -Drhino.debugger.port=9123

     

• From eclipse, click on down arrow next to debug menu and choose debug configurations.

    

If debug menu is not visible: Go to Windows > Customize Perspective. "Navigate to Commands group visibility" tab. Then select "Launch" option in the Availability Command Groups and click OK.

• On the new window opened, provide below details:

    

• Navigate to Source tab and provide the path to the script file and click on Debug.

   

• Open JavaScript file and set a break point as given below.

    

• Execute the Odata service from a rest client by passing City as header along with Authorization header.

• It triggers the break point set in the Javascript. To see the data send from rest client (ie. City) add Expression String(child) as given below. If Expressions tab not visible: Go to Windows > Show view > Expressions.
