[jboss-user] [JBoss Portal] - Re: Redirect portal

[alessio.papi]

Hi,

my idea (implemented in my project) was to extend DefaultPortalCommandFactory and SignOutURLFactory to change the page/URL to redirect to role default page. The two factoris replace the standard factories CommandFactory and SignOutURLFactory.

For example, the redirect to home factory is something like this :


public class RedirectHomeFactory extends DefaultPortalCommandFactory {

	/** Log */
	private static final Log LOG = LogFactory.getLog(RedirectHomeFactory.class);
	
	/** Slash */
	private static final String SLASH = "/";
	
	/** Mapping */
	private Properties mapping;
	
	/**
	 * Get mapping
	 * @return Mapping
	 */
	public Properties getMapping() {
		return mapping;
	}

	/**
	 * Set mapping
	 * @param mapping Mapping
	 */
	public void setMapping(Properties mapping) {
		this.mapping = mapping;
	}

	/**
	 * {@inheritDoc}
	 */
	@Override
	public ControllerCommand doMapping(ControllerContext context, ServerInvocation serverInvocation, String host, String contextPath, String requestPath) {
		// Command
		ControllerCommand command = null;
		// Get http request and check roles
		HttpServletRequest request = serverInvocation.getServerContext().getClientRequest();
		
		// Redirect only if portal is not specified
		if (requestPath != null && (requestPath.trim().length() == 0 || requestPath.trim().equals(SLASH))) {
			// Flag
			boolean found = false;
			// Role
			String role = null;
			
			// Get roles
			Enumeration enumeration = mapping.keys();
			
			while (!found && enumeration.hasMoreElements()) {
				// Get role
				role = (String) enumeration.nextElement();
				
				// Check role
				if (request.isUserInRole(role)) {
					// Get portal and page of role
					String[] portalAndPage = mapping.getProperty(role).split(SLASH);
						
					if (portalAndPage == null || portalAndPage.length < 2) {
						throw new IllegalStateException("Wrong portal/page for role " + role);
					}
					
					// Get portal
					Portal portal = getContainer().getContext().getPortal(portalAndPage[0]);
					 
					if (portal == null) {
						throw new IllegalStateException("Default portal does not exist");
					}
					
					// Get default page
					Page page = portal.getPage(portalAndPage[1]);
					
					if (page == null) { 
						throw new IllegalStateException("Default page does not exist");
					}
					
					// Log
					LOG.debug("Redirect to " + portal.getName() + " " + page.getName());
					
					command = new ViewPageCommand(page.getId());
					found = true;
				}
			}
			
			if (!found) {
				// Log
				LOG.debug("Default redirect, no mapped role");
			
				// Default command
				command = super.doMapping(context, serverInvocation, host, contextPath, requestPath);
			}
		} else {
			// Log
			LOG.debug("Default redirect");
			
			// Default command
			command = super.doMapping(context, serverInvocation, host, contextPath, requestPath);
		}
		
		return command;
	}

}



and the mbean that replace the standard portal mbean :


  	<!-- Redirect to user home -->
	<mbean code="com.yourcompany.RedirectHomeFactory"
		   name="portal:commandFactory=RedirectHome" xmbean-dd=""
		   xmbean-code="org.jboss.portal.jems.as.system.JBossServiceModelMBean">
		 
		 
		 	role=portal/default
         
		 <depends optional-attribute-name="NextFactory" proxy-type="attribute">portal:commandFactory=Delegating
		 <depends optional-attribute-name="Container" proxy-type="attribute">portal:container=PortalObject
	


you have to change the portal mbean controller properties  :


<!-- 
      <depends
              optional-attribute-name="CommandFactory"
              proxy-type="attribute">portal:commandFactory=DefaultPortal
      
      -->
      <depends
              optional-attribute-name="CommandFactory"
              proxy-type="attribute">portal:commandFactory=RedirectHome
      



For the signout the code is the same :


public class SignOutFactory extends SignOutURLFactory {

	/** Log */
	private static final Log LOG = LogFactory.getLog(SignOutFactory.class);
	
	/** Location */
	private static final String LOCATION = "location";
	
	/** Mapping */
	private Properties mapping;
	
	/**
	 * Get mapping
	 * @return Mapping
	 */
	public Properties getMapping() {
		return mapping;
	}

	/**
	 * Set mapping
	 * @param mapping Mapping
	 */
	public void setMapping(Properties mapping) {
		this.mapping = mapping;
	}

	/**
	 * {@inheritDoc}
	 */
	@Override
	public ServerURL doMapping(ControllerContext context, ServerInvocation serverInvocation, ControllerCommand controllerCommand) {
		// URL
		ServerURL serverURL = super.doMapping(context, serverInvocation, controllerCommand);
		
		if (serverURL != null) {
			// Get http request and check roles
			HttpServletRequest request = serverInvocation.getServerContext().getClientRequest();
			
			// Flag
			boolean found = false;
			// Role
			String role = null;
				
			// Get roles
			Enumeration enumeration = mapping.keys();
				
			while (!found && enumeration.hasMoreElements()) {
				// Get role
				role = (String) enumeration.nextElement();
					
				// Check role
				if (request.isUserInRole(role)) {
					// Get location for role
					try {
						serverURL.setParameterValue(LOCATION, URLEncoder.encode(mapping.getProperty(role), "UTF-8"));
					} catch (UnsupportedEncodingException encEx) {
						LOG.error("Unsupported encoding " + encEx);
					}
					
					found = true;
				}
			}
		}
		
		return serverURL;
	}

}


the mbean :


	<!-- Redirect to user login -->
	<mbean code="yourcompany.SignOutFactory"
		   name="portal:urlFactory=SignOut" xmbean-dd=""
		   xmbean-code="org.jboss.portal.jems.as.system.JBossServiceModelMBean">
		 
		 
			role=portal/YourPortal
         
		 /signout
      	 <depends optional-attribute-name="Factory" proxy-type="attribute">portal:urlFactory=Delegating
	


and comment out the portal signout mbean :


   <!-- 
   <mbean
           code="org.jboss.portal.core.controller.command.mapper.SignOutURLFactory"
           name="portal:urlFactory=SignOut"
           xmbean-dd=""
           xmbean-code="org.jboss.portal.jems.as.system.JBossServiceModelMBean">
      
      /signout
      <depends
              optional-attribute-name="Factory"
              proxy-type="attribute">portal:urlFactory=Delegating
      
   
   -->


This solution redirects to default role portal only if the user doesn't specify the complete URL, to prevent users to go to another portal you have to add security-constraint into your portal-object.xml file.
