To Secure the Example Web Service Client Application (SV)

This section demonstrates adding security to the web service client that references the web service created in the previous section. This web service is secured using the security mechanism described in SAML Sender Vouches with Certificates.

To add security to the client that references this web service, complete the following steps.

This example uses a non-JSR-109-compliant client. To do this, create the client application up to the step where you create the Servlet (step 7 as of this writing) by following the steps described in Creating a Client to Consume a WSIT-Enabled Web Service, with one exception: name the application CalculatorClient (since it’s not a servlet.).

Instead of creating a client servlet as is described in Creating a Client to Consume a WSIT-Enabled Web Service, just add the web service operation to the generated index.jsp file to create a non-JSR-109 client. To do this, follow these steps:
1. If the index.jsp file is not open in the right pane, double-click it to open it.
2. Drill down through the Web Service References node until you get to the add operation.
3. Drag the add operation to the line immediately following the following line:
```
    <h1>JSP Page</h1>
```
4. Edit the values for i and j if you’d like.

Write a SAMLCallback handler for the client side to populate a SAML assertion into the client’s request to the service.

To create the SAMLCallbackHandler, follow these steps:
1. Right-click the CalculatorClient node and select New->Java Package.
2. For Package Name, type xwss.saml, then click Finish.
3. Drill down from CalculatorClient->Source Packages->xwss.saml.
4. Right-click xwss.saml and select New->File/Folder.
5. From the Categories list, select Java Classes.
6. From the File Types list, select Empty Java File and click Next.
7. For Class Name, type SamlCallbackHandler, then click Finish.
  
  The empty file appears in the IDE.
8. Download the example file SamlCallbackHandler.java from the following URL: https://xwss.dev.java.net/servlets/ProjectDocumentList?folderID=6645[amp ]expandFolder=6645[amp ]folderID=6645
9. Open the file in a text editor.
10. Modify the home variable to provide the hard-coded path to your GlassFish installation. For example, modify the line:
```
        String home = System.getProperty("WSIT_HOME");
```
  to
```
        String home = "/home/glassfish";
```
11. Set the subject confirmation method to SV (Sender Vouches). For more information on this topic, read Example SAML Callback Handlers.
12. Copy the contents of this file into the SamlCallbackHandler.java window that is displaying in the IDE.

Drill down from CalculatorClient->Web Service References.

Right-click on CalculatorWSService and select Edit Web Service Attributes.

Select the WSIT Configuration tab of the CalculatorWSService dialog.

Provide the client’s private key by pointing to an alias in the keystore. To do this, expand the Certificates node, click the Load Aliases button for the keystore, then select xws-security-client from the Alias list.

Provide the server’s certificate by pointing to an alias in the client truststore. To do this, from the Certificates node, click the Load Aliases button for the Truststore and select xws-security-server.

Expand the Username Authentication node. In the SAML Callback Handler field, type the name of the class written in step 3 above, xwss.saml.SamlCallbackHandler.

Click OK to close this dialog.

In the tree, drill down from the project to Source Packages->META-INF. Double-click CalculatorWSService.xml, and verify that lines similar to the following are present, where xwss.saml.SamlCallbackHandler is the SAML Callback Handler class for the client:

<wsp:All>
  <wsaws:UsingAddressing xmlns:wsaws="http://www.w3.org/2006/05/addressing/wsdl"/>
  <sc:CallbackHandlerConfiguration wspp:visibility="private">
    <sc:CallbackHandler name="samlHandler" classname="xwss.saml.SamlCallbackHandler"/>
  </sc:CallbackHandlerConfiguration>
  <sc:KeyStore wspp:visibility="private" 
    location="as-install\domains\domain1\config\keystore.jks"
    storepass="changeit" alias="xws-security-client" keypass="changeit"/>
  <sc:TrustStore wspp:visibility="private" 
    location="as-install\domains\domain1\config\cacerts.jks"
    storepass="changeit" peeralias="xws-security-server"/>
</wsp:All>

Compile and run this application by right-clicking the CalculatorClient node and selecting Run Project.
