My Spring MVC application is runnning on a Tomcat behind an Apache 2 acting as a proxy. I access my app directly in tomcat via an url like http://localhost:8080/myapp. I access my app via proxy with an url like http://localhost/tomcat/myapp.
The second url makes my app behave incorrectly, because it supposes it lives in /myapp context path, but via the proxy it should live in /tomcat/myapp.
Is there a variable in Spring or Servlet API, that holds /tomcat/myapp if I am accessing it via the proxy, and /myapp if I am accessing it directly?
Thanx
I think you need to enable proxy support then. This link might help you or give a little hint in this regards.

Just stumbled upon this post while searching for the config setting for tomcat.
There is a much easier way to configure tomcat to handle the exact situation you are experiencing. See:
http://tomcat.apache.org/tomcat-5.5-doc/proxy-howto.html
Simple configure a connector for the proxy in tomcat, and the servlet/struts context path issues will resolve.
-edit: Obviously I didn't read #2 comment...
I mean when I redirect to "/index.jsp"
it actually redirects to
"http://localhost/myapp/index.jsp"
instead of
"http://localhost/tomcat/myapp/index.jsp"
Redirect to index.jsp instead of /index.jsp
When you redirect to /index.jsp this acts as an absolute url and it gets redirected to myapp/index.jsp. index.jsp is a relative url and will redirect to tomcat/myapp/index.jsp

Currently I'm facing issue with redirecting application which is behind proxy server:
To see application I need to go to:
http://myserver.net/PREFIX/configuration
And I need to add PREFIX to every url which will be returned by spring. Currently after successful logging with spring security when I return
.successForwardUrl("/configuration")
It's redirecting me to url address which is not existing:
http://myserver.net/configuration
Is there any possibility to add Tomcat prefix to dispatcher servlet? To make somehow default path for the application:
http://myserver.net/PREFIX/
I was trying to use:
server.servlet.contextPath=PREFIX
But problem is that when I use context path, I need to go
http://myserver.net/PREFIX/PREFIX/configuration
To be redirected properly to spring controller. Maybe there is possibility to set up context path but only for response?
So I have let's say an application named MyApplication. I deploy it with a virtual server on glassfish and all is well since I set the default welcome page. Let's say the virtual server is to listen on mydomain.com
I goto mydomain.com and i see my index file of my application just fine. Then i go to do a j_security_check login.
And i am then redirected to: http://mydomain.com/MyApplication/page.xhtml
How can I get this to wehre it is: http://mydomain.com/page.xhtml ?
Now if I do take MyApplication out of the URL and try to manually goto that page it is blank, as I believe it is not being processed by JSF.
What I have tried.
* Setting the default glassfish application to my application and setting the context path of my application to / (glassfish complains and i cannot deploy my application)
* Doing the same as above without setting my context path to / and leaving it as is.
Will deploy but same issue.
My main reason for wanting this, is it seems if someone does get redirected to a path without the application name, the session state appears to be different. And causes some sporadic issues with session collision and values not being passed properly. So I either want to force the URLS to use the ApplicationName all the time, OR force them to not use it for the sake of consistancy.
There should be a way to accomplish this since I dont believe we should always have to have the ApplicationName in the URL.
Please help if you can, what I have found by searching seems to take care of it for the initial request but not when doing redirects using the FacesContext extenralContext redirect.
Unless I am not redirecting properly. I am at a loss here.
Thank you for the help.
IMHO you should consider using asap PrettyFaces
Your application URLs will always be elegantly displayed to your users.
I created index.jsp page and binded path /index to it in web.xml. It's also displayed when accessing the root of application as welcome page. It has three init parameters.
The problem is I can access then from JSP code by config.getInitParameter() if the path is full [host:port]/[appName]/index, the parameters are accessed normally. If I try to navigate to application root [host:port]/[appName]/ welcome page is displayed but init parameters can't be accessed. config.getInitParameter() method returns null.
How to configure welcome page properly in web.xml if I want to get servlet init parameters?
Do you have index.jsp defined as a "welcome-file" in web.xml? It sounds like the container is doing a redirect. Defining index.jsp as a welcome-file should fix that.
Hope that helps.
Usually in Java, if you want to use / to access a Java EE context, you would either:
Mount it on the ROOT context.
Use a reverse proxy (like nginx).
The second method is the most common solution. In this case the request goes Browser -> Reverse Proxy / Load Balancer -> One or more application servers.
This has several advantages.
You can handle SSL handshaking on the Reverse Proxy.
Your application server can deliver content as fast as it can to the Reverse Proxy (which is usually faster than to the browser) so it doesn't tie up the connection as long (spoon feeding).
You can display meaningful error pages even if the Java EE container isn't running.
Having a different domain, or subdomain for serving each context is trivial.
I am trying to use JAAS for my servlet application. I could get a basic JAAS simple authentication (non-servlet) working.
But with the servlet where to i set this variable?
-Djava.security.auth.login.config=test_jaas.config
I also tried exporting JVM_OPTS to this as per this page http://www.kopz.org/public/documents/tomcat/jaasintomcat.html
But I still keep getting, "No LoginModules configured" while creating LoginContex.
Any help is appreciated.
It depends on the servlet container. If you're using Tomcat you have to configure a JAAS realm. See the Tomcat configuration documentation under Realms.
instead you can go to java_home/conf/security/java.security and add your config location by adding the following
login.config.url.1=file:[test_jaas.config path]
I am new to J2EE and related stuff in general. I am trying to move a particular web application from a Sun One server deployment on to JBoss. The application is filled with a lot of servlets where each one re-directs to another.
There are way too many servlets for me to enter a mapping between each of these servlet class to a URL-mapping individually in web.xml. The application code has many redirects where they name the servlet class names itself in the redirect-URL. As of now when I run it on JBoss the redirections to URL with servlet classnames in URL don't seem to work on JBoss (it gives a 404: Not Found, probably since there is no mapping in the web.xml). So is there any config setting that I can set to allow this to happen or should manually enter each and every URLpattern-to-Servlet mapping in the web.xml?
Thank you.
There are two solutions.
As we know JBoss uses Tomcat under the hood as a servlet container. You can enable invoker servlet, that would save you from mapping the whole lot in web.xml. But beware, it will be naive to do that, and not at all encouraged.
Secondly, you can write another servlet/filter and map just that in your web.xml for every url pattern, may be. Then that new servlet of your can forward the requests to whatever servlet it should.
I hope you get my point.
Not sure what you mean by this
the application code has many redirects where they name the servlet class names itself in the redirect-URL
Do you have hardcoded urls in the servlet classes? How many servlets? If you have hardcoded urls they may all have broken because the context is slightly different, or the appname, etc.etc. Can you post an example?
Well, there are some hard-coded URLs in the code, but even if i typed in the right URLs in browser directly I still get a 404. There are about 30 servlets (a conservative approximation). Ex: http://FQDN_SERVER.com/?arg1=ABCD&arg2=XYZ
Here the servlet-classname is literally the classname of the servlet without ".class" extension, which may not be a good practice. But the code is full of such redirections and if I have to change this then I have to add a new url-pattern to each of these servlets in the web.xml and construct a new red-rect URL for each of these servlets. So is there anyway I can avoid this or will I have to go through the pain of doing the above mentioned?
Thanks,
Manoj
Sorry the URL-pattern looks this http://FQDN_SERVER.com/servlet-classname?arg1=ABCD&arg2=XYZ
