Subject Multiple Aliases Problem
Date Mon, 21 Nov 2011 06:52:28 GMT
Hi community.
I am working on embedding a Tomcat server into my project.

I have 2 domain name called localhost1 and localhost2.
I created a Host instance with the localhost1 domain name.

Host host = new StandardHost();
host.setAppBase(CATALINA_HOSTS_HOME);
host.setName("localhost1");
host.setDeployOnStartup(false);
host.setBackgroundProcessorDelay(5);
host.setAutoDeploy(false);
host.setRealm(engine.getRealm());
engine.addChild(host);

Then I added the localhost2 as a alias.

host.addAlias("localhost2");

If I entered localhost1 at a browser then it works fine but if I entered
localhost2 at the browser then I got an error:

I solved this problem by adding some codes into the trunk:

         if (insertMap(hosts, newHosts, newHost)) {
+            Object object = newHost.object;

+            }
             hosts = newHosts;
         }
     }


Do you think I am doing in the right track and this fixed should be
committed into the trunk? If not, could you please give me a solution to
solve the problem?
