An objected oriented shell code generating tool receives data that identifies a Web service hosted by a server. The tool creates proxy code to generate a Web service client proxy to identify a plurality of methods for the Web service. For each method, the tool automatically creates object driven shell commands code that defines a class implementing parameters of the Web service method, wherein the object driven shell commands code is to be executed in an object driven shell platform to communicate with the Web service method via the client proxy. The tool generates invocation infrastructure code for communicating to the Web service method via the client proxy and deploys the proxy code, the invocation infrastructure code, and the object driven shell commands code in the object driven shell platform on the client to call a Web service method via the invocation infrastructure and the client proxy.
