This page describes a HTTP logging facility created to aid in Axis development.

See also FrontPage/Axis/DynamicSSLConfig for more information about the SSL setup.
See also FrontPage/Axis/Logging/Logging_with_SSL for more information about logging HTTP messages.

The Problem

Axis comes with a LogHandler which can be used to dump SOAP requests/responses to a log file. Normally, this works very well, but has the following shortcomings:

The Solution

A new Axis Handler was written for logging. Essentially, this is modelled on the original LogHandler class, with the following differences:

This allows an application to access the handler, and then access the logs

Usage / Configuration

To use the logging facility, add the classes downloaded from this page to your web service client application.

The following is a sample of using the in memory SOAP logging:

   1 // create config
   2 boolean logging = true; // activate logging
   3 SSLClientAxisEngineConfig axisConfig = new SSLClientAxisEngineConfig();
   4 axisConfig.setKeystore("/path/to/clientkey.p12");
   5 axisConfig.setKeystoreType("PKCS12");
   6 axisConfig.setKeystorePassword("changeit");
   7 axisConfig.setTruststore("/path/to/truststore.jks");
   8 axisConfig.setTruststoreType("JKS");
   9 axisConfig.setTruststorePassword("changeit");
  10 if (logging)
  11     axisConfig.setDebugBaseDir("/path/to/logs");
  12 axisConfig.initialize(logging);
  13 // initialize service
  14 URL soapURL = new URL("https://myserver.com/myapp/services/mywebserviceport");
  15 MyWebServiceServiceLocator locator = new MyServiceLocator(axisConfig);
  16 MyWebServicePort port = locator.getMyWebServicePort(soapURL);
  17 MyWebServiceBindingStub stub = (MyWebServiceBindingStub) port;
  18 // make a call to the webservice (assume no params for this operation)
  19 MyResultType result = stub.myoperation1();

Note: In the example above it is assumed that you have created the client stubs for the web service "MyWebService" using the Axis WSD!L2Java tool.

After the call to myoperation() the log directory specified should contain 2 more files, one with "request" in the filename (the request), and one with "response" in the filename, the response.

To access the logs within the application, do something like this:

   1 AxisDebugLogHandler handler = axisConfig.getLogHandler();
   2 String reqStr = handler.getReqMessage();
   3 String respStr = handler.getRespMessage();

You can now work with the SOAP message strings within your application, for example to log them to your own integrated logs, or display them to the user, or send them as part of an automated bug report, etc...
