Dependencies with other extensions

The REST Service Calls for Java extension requires that ≥ 1.2.8-funcrel of the JEE Analyzer is also installed and used in order to ensure the most complete set of results. This dependency with the JEE Analyzer is not automatically handled when downloading the REST Service Calls for Java extension via CAST Extension Downloader, CAST Server Manager or AIP Console, therefore you must MANUALLY download and install the JEE Analyzer before starting an analysis.

Download and installation instructions

Please see:

Packaging, delivering and analyzing your source code

Package your JEE code as described in JEE - Prepare and deliver the source code - the REST Service Calls for Java extension will be run when you perform the analysis.

Features

This extension analyses some web services call made from Java code through some classical fluent APIs. For example with com.sun.jersey:

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;


class Main
{
	public static void main(String[] args) {
		Client client = Client.create();

		WebResource webResource = client
				.resource("http://localhost:8080/RESTfulExample/rest/json/metallica/get");

		ClientResponse response = webResource.accept("application/json")
				.get(ClientResponse.class);

	}

}

Rules

None.

Limitations

• When the code uses a custom URL builder, we cannot evaluate the URL.
• When the standard java API is encapsulated in a custom method where the "http method" (put, get, post, delete) is passed as a parameter, the dynamic evaluation will generally fail.

class MyHttpCall
{
   void execute(String url, String method)
   {
      Client client = ClientBuilder.newClient();
      WebTarget myResource = client.target(url);

      if (method == "GET")
      {
          String response = myResource.request(MediaType.TEXT_PLAIN).get(String.class);
      }
      else if (method == "PUT")
      {
          myResource.request(MediaType.TEXT_PLAIN).put(null);
      }
         
   }
