Class Summary

RequestHandler

This class extends HandlerBase and is used to handle events created as an XML document is parsed by a SAX compliant parser.

Package examples.xml.attributes Description

This example demonstrates how to automatically parse a document using WebLogic Servlet request attributes.

In the example, a Client sends an XML file over HTTP to a JSP running on the WebLogic Server. The JSP uses the WebLogic Servlet request setAttribute method to parse the document using the SAX parser.

The example illustrates how to:

• read an XML file and write it to an output stream.
• parse XML data using the setAttribute method on the request.
• pass XML data between a client and a JSP via an HTTP POST.

Additional Resources for examples.xml.attributes

Attribute.jsp	The JSP that receives the XML data from the Java Client, parses it using the setAttribute method, and sends an acknowledgement back to the Client over HTTP.
employee.xml	The XML file that is between the Java Client and the JSP over HTTP.

The following section describes how to build and run the example:

1. Build the example
2. Run the example

Build the example

1. Set up your development shell as described in Setting up your environment.

2. Compile the example by executing the Java ant command. The Java ant command uses the build.xml file, located in the samples/examples/xml/attributes directory, to build the example. The Java Ant command performs the following steps:
   1. Compiles the Client.
   2. Compiles the RequestHandler class into WEB-INF/classes directory of the examples Web application.
   3. Copies the Attribute.jsp file into the examples Web application.
   4. Compiles the JSP Attribute.jsp under WEB-INF\classes of the examples Web application.

Run the Example

1. Start the WebLogic Server in a new command shell.

2. In your development shell, run the Client with the following command:

     $ java examples.xml.Client http://hostname:port/examplesWebApp/Attribute.jsp employee.xml

   where:

   hostname

   Host name of the WebLogic Server.

   port

   Port where the WebLogic Server is listening for connections (weblogic.system.ListenPort).
