MapListener update
Hi ,
When I update my code for embedding tomcat 5.x to embedding 6.x, a null
pointer exception blocks me .
I dug the code , I found it cause by the
org.apache.catalina.connector.MapperListener difference :
Tomcat5.x
---
/**
* Register host.
*/
private void registerHost(ObjectName objectName)
throws Exception {
String name=objectName.getKeyProperty(host);
if( name != null ) {
String[] aliases = (String[])
mBeanServer.invoke(objectName, findAliases, null, null);
mapper.addHost(name, aliases, objectName);
if(log.isDebugEnabled())
log.debug(sm.getString
(mapperListener.registerHost, name, domain));
}
}
Tomcat6.x
-
/**
* Register host.
*/
private void registerHost(ObjectName objectName)
throws Exception {
String name=objectName.getKeyProperty(host);
if( name != null ) {
Host host = (Host) ServerFactory.getServer().findService(
domain).getContainer().findChild(name);
String[] aliases = host.findAliases();
mapper.addHost(name, aliases, objectName);
host.addContainerListener(this);
if(log.isDebugEnabled())
log.debug(sm.getString
(mapperListener.registerHost, name, domain));
}
}
Is this change to fix an issue ? Or Tomcat6.x totally change the host name
looking up mechanism .
Could you also point to me where can I find the Tomcat6.x document about
difference with Tomcat5.x if there is ? for example architecture , execution
etc.
Thanks in advance .

Thanks , Chunk. The problem is that I can not simply correct that URL and send it for the f first time. The request url is generated by other application or in some condition sometimes provided by user . The client side can not judge http://localhost:8080/foo; is a request for foo resource in root context or a request url for the default page in foo context. Server side has that information and can judge it . If there is a foo context , it will reply the redirect response. httpunit can help that. Actually I want to know if there is second option(configure tomcat to support that ) .
Re: How to prevent Tomcat redirect my request
Tell your clients to generate URLs like: http://host/your_servlet?url=url_to_fetch In other words you should implemet proxy that will handle redirects itself. Finally, your clients will not see any 302 redirects. I like this idea. It is greatly helpful , I think it works for my problem. -- Mikolaj Rydzewski [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
How to prevent Tomcat redirect my request
Hi all, I deployed a web application foo.war into tomcat 5.x . When I used httpclient to send post request to http://localhost:8080/foo;, I always get the http 302 redirect response . How can I prevent Tomcat to reply redirect response and directly adding the slash to my request url http://localhost:8080/foo/; to get what I want . I see web browser can automcatically resend the request to redirected location but httpclient can not. Is there configurations for that ? Could anyone shed some lights ? Thanks Jim
Re: How to prevent Tomcat redirect my request
Great thanks , Kees. I will try httpunit . I still want to know if it is possible to stop Tomcat from redirecting. If yes, that will be zero code effort for our current implementation.

I usually use httpunit, not httpclient. The advantage is that it does all the cookies, 302 responses and lord knows what else in the HTTP protocol, allowing me to focus on the logic instead of the protocol. Maybe that's an alternative route for you, if Tomcat cannot be stopped from redirecting your app. -- Kees Jan http://java-monitor.com/forum/ [EMAIL PROTECTED] 06-51838192 Rule 1 for being in a hole: stop digging. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: returning error messages from tomcat to http clients?
The simple way is returning the http OK 200 status code instead of 500 , and set the error message to response body. Does it work for you ?

Yes, that's true of course. Stupid me. Urlrewrite is a servlet filter, so it will not see the request before it has been directed to the webapp, and thus the redirect will happen before. Duh. I guess you would need some kind of re-directing Valve for that. I also try to add a rewrite Valve to StandardEngine. And it is also does not work . Before reach that Valve, tomcat already replied that redirect response. Now, about what Mikolaj wrote before (using the /foo/ URL) I think you misunderstand what he is saying. What he meant is probably this : You seem to be using a http client that is not a browser, but some kind of program or module. Can you not make sure that this program or module does not send URLs like /foo, but itself transforms them into /foo/ at the source ? Yes , I can do that . If I get 302 response and write some code to resend quest to the redirected location, then I can always get what I want . It is not efficient , you know. It needs to talk to tomcat server twice . Is there shortcut way to do that ?
