1. Install GlassFish (unless its already installed). You can download GlassFish from the GlassFish Project-Download Binary Builds page. Select a build that's appropriate for your environment and download it. Then follow the instructions on the Download page to complete the installation.
   
   
2. Set the following environment variables:
   
   S1AS_HOME. This should point to where you installed GlassFish (for example C:\Sun\AppServer)
   ANT_HOME. This should point to where ant is installed. Ant is included in the GlassFish bundle that you downloaded. (In Windows, it's in the lib\ant subdirectory.)
   JAVA_HOME. This should point to the location of JDK 5.0 on your system.
   
   Also, add the ant location to your PATH environment variable.
   
   
3. Download the sample package. Then change to the directory where you downloaded the package and unzip the package. The result is a directory called resources that contains the source files and other support files for the sample.
   
   
4. Change to the resource directory and edit the config.properties files as appropriate. For example, if the admin host is remote change admin.host from the default value (localhost) to the appropriate remote host.
   
   
5. Start GlassFish by entering the following command:

      asadmin start-domain --user admin --password 
          administrator domain1
   

6. Run following commands:

      ant build 
   

   This will compile classes and create an EAR file. Class files and EAR files are generated inside the resources/ejb30 directory.

     
      ant setup 
   

   This will deploy necessary resources onto GlassFish.

      
      ant deploy 
   

   This will deploy the created EAR file.

      
      ant run 
   

   This will run an application client and invoke the deployed EAR file. You should see the following in response:

        
   runclient-common:
       [echo] Executing appclient at 
          C:\ws\appserver-sqe\pe\ejb\ejb30\session\stateful\resources
       [exec] Invoking 3.0 SFSB-------->
       [exec] Message from 3.0 SFSB: hello
       [exec] invoking stateless...
       [exec] Message from 3.0 Stateless Bean: Hello from 
        Stateless bean
       [exec] SFSB Invoked Stateless Bean successfully
       [exec] Message from 3.0 Stateless Bean to SFSB: 
        Hello from Stateless bean: SFSB Invoked Sless
       [exec] Removed SFSB by calling remove business method:
       [exec] Test Complete--------------> 
   

7. After running the sample, you can undeploy it and delete any resources created in GlassFish through the following commands:

      
      ant undeploy 
   

   This undeploys the application.

        
      ant unsetup 
   

   This deletes all the resources created in GlassFish.

1. Which of the following is a "pull" parser?
   1. Xerces
   2. SSAX
   3. Sun Java Streaming XML Parser (SJSXP)
   4. None of the above
   
   
   
2. Which of the following WSDL binding style/use combinations are WS-I compliant?
   1. RPC/encoded
   2. RPC/literal
   3. Document/encoded
   4. Document/literal
   5. None of the above
   
   
   
3. Which of the following is a valid binding expression in JavaServer Faces (JSF) technology?
   1. #{invoice.customerName}
   2. ${invoice.date}
   3. #[customer.status == 'VIP']
   4. None of the above.
   
   
   
4. What do the following elements in a web.xml deployment descriptor specify:

      
      <local-encoding-mapping-list>
           <local-encoding-mapping>
             <locale>ja</locale>
             <encoding>Shift_JIS</encoding>
           </locale-encoding-mapping>
           <locale-encoding-mapping>
             <locale>zh_TW</locale>
             <encoding>Big5</encoding>
           </locale-encoding-mapping>
      </locale-encoding-mapping-list>
    

   1. Use the Shift_JIS charset for any servlet response whose locale is set to ja, and the Big5 charset for any servlet response whose locale is set to zh_TW Traditional Chinese.
   2. Include the Shift_JIS charset in the list of character sets that the container can choose from for servlet responses whose locale is set to ja, and include the Big5 charset in the list of character sets that the container can choose from for servlet responses whose locale is set to zh_TW Traditional Chinese.
   3. Nothing -- there is no <locale-encoding-mapping-list> element.
   
   
   
5. Which of the following statements are true about message-driven beans:
   1. A message-driven bean's instances retain no data or conversational state for a specific client.
   2. All instances of a message-driven bean are equivalent, allowing the EJB container to assign a message to any message-driven bean instance.
   3. A single message-driven bean can process messages from multiple clients.
   4. All of the above.
   5. None of the above.
   
   
   

1. Which of the following is a "pull" parser?
   
   c) Sun Java Streaming XML Parser (SJSXP). SJSXP is a high-speed implementation of the Streaming API for XML parser (StAX). SJSXP is a pull parser (by comparison, Xerces and SSAX are SAX parsers). SJSXP implements a pull method, where the parser maintains a pointer of sorts to the currently-scanned location in the document--this is often called a cursor. You simply ask the parser for the node that the cursor currently points to by using either of two APIs that SJSXP provides: cursor and iterator. The cursor API returns the XML information as strings, while the iterator API returns discrete event objects in the order in which they are read by the parser. For more information about SJSXP, see the February 22, 2005 Tech Tip Introducing the Sun Java Streaming XML Parser.
   
   
2. Which of the following WSDL binding style/use combinations are WS-I compliant?
   1. RPC/encoded
   2. RPC/literal
   3. Document/encoded
   4. Document/literal
   5. None of the above
   b and d. RPC/literal and Document/literal are WS-I compliant. You can learn more about the binding style/use combinations in the June 22, 2005 Tech Tip JAX-RPC Binding Styles and Use Attributes.
   
   
3. Which of the following is a valid binding expression in JavaServer Faces (JSF) technology?
   
   a) #{invoice.customerName}
   
   The syntax of binding expressions is based on the JavaServer Pages (JSP) 2.0 Expression Language, which itself is based on the object accessing syntax of JavaScript. In JSP, expressions are delimited with "${}", but in JSF they are delimited with "#{}". Learn more in the September 23, 2004 Tech Tip Value and Method Binding Expressions in JavaServer Faces Technology. Note that updates have been made in JSF 1.2 to unify its expression language with JSP 2.1. For more about the new, unified expression language, see the technical article Unified Expression Language.
   
   
4. What do the following elements in a web.xml deployment descriptor specify:

      
      <local-encoding-mapping-list>
           <local-encoding-mapping>
             <locale>ja</locale>
             <encoding>Shift_JIS</encoding>
           </locale-encoding-mapping>
           <locale-encoding-mapping>
             <locale>zh_TW</locale>
             <encoding>Big5</encoding>
           </locale-encoding-mapping>
      </locale-encoding-mapping-list>
   

   a) Use the Shift_JIS charset for any servlet response whose locale is set to ja, and the Big5 charset for any servlet response whose locale is set to zh_TW Traditional Chinese. The Java Servlet 2.4 API introduced a new <locale-encoding-mapping-list> element in the web.xml deployment descriptor. This allows you to assign locale-to-charset mappings. For more information, see the April 25, 2005 Tech Tip Improved Internationalization in the Java Servlet 2.4 API.
