In my gwt application,i am using php code for back end process...i can get response from that php file when i deploy on iis server...
but i can't get response from that php file when i running from the eclipse...
(i.e)
can get response from this url "http://localhost/sample/index.php"
can't get response from this url "http://localhost:8888/sample/index.php" it returns my php code...
It's probably possible to run PHP on Jetty, too: See these instructions - not sure, if they still work with Jetty 6, and I really haven't tried it.
But I would recommend to simply run a separate PHP server (maybe deployed from a separate Eclipse project). See this GWT FAQ entry: How do I use my own server in hosted mode instead of GWT's built-in Jetty instance
You could use the gwt -noserver option
"The -noserver option instructs hosted mode to not start the embedded Jetty instance. In its place, you would run the J2EE container of your choice and simply use that in place of the embedded Jetty instance."
I don't know if this would solve your problem

I am trying to call a servlet form my android application in eclipse. I have to use the Glassfish application server(the servlet is in a different Mavan project). I had a few questions:
How to start a glassfish server in Eclipse?
What URL do I pass in the HttpPost() method?
Thank you.
There is the Servers view in which you can add you GF instance. However, this is not mandatory and you can run it from the command line (asadmin).
If your GF runs locally, the URL will start with
http :// localhost/webappName/servletPath
localhost or 127.0.0.1
I'd advise you to get a training as the more you'll progress, the more questions you'll have.
I'm having trouble wrapping my head around how to use servlets properly
I've set up a postgres database, and downloaded a JDBC driver for it.
What I want to have is my webpages post to the servlet, and the servlet get info from the database. I understand how to code everything (eg add library for driver, open connections, execute queries), but I think I'm lacking knowledge in how to set up the file structure.
I have the postgresql database running on pgAdmin. Do I also need to have a server running to make the servlets work as well? Can't I just make a web.xml file that maps to the servlets, and open the webpages to use the website? If I run the project through an IDE with a server running (glassfish) everything works. If I close the IDE and go to open the webpages on my browser again, I get 404's whenever I submit to a servlet.
Can someone give me a bit of guidance on the big picture of how everything is supposed to interact (with details on servers please). I've been searching the web and I havent found anything that explains the big picture very well.
Thanks
A Java web application is a set of files obeying a well-defined structure, and which can be packaged in a war file.
This web application is deployed into a server (also called container), which understands the file structure, listens to HTTP requests, and calls the appropriate servlet of the appropriate deployed web application when it receives one.
And of course, if you shut down the server, nothing listens to the HTTP requests anymore, so you won't get any response.
You could read the Java EE tutorial for more explanations.
While there are some similar posts about this issue, none seem to fit my problem exactly, so I would like to ask if anyone knows what I am doing wrong.
I am trying to run a PHP web application that I created in Netbeans. I am using Glassfish 3.1.1 as the web server. Whenever I run the application through Netbeans (by selecting the project, right clicking to get the context menu, then selecting "Run"), my browser opens to what I believe to be the correct url, but all I get is a 404 error page stating the following:
type: Status report
message:
description:The requested resource () is not available.
Am I missing some crucial configuration step?
I have checked my hosts file and it contains the entry:
127.0.0.1 localhost
Is there something else I need to do?
I have PHP 5.3.8 installed and all php commands run from the command line.
Would it be something in the php.ini file that needs to be configured?
I am stumped. Any help would be greatly appreciated.

Please accept the comment below from Jonathan Spooner as the correct answer.
Just install Quercus within GlassFish 3.x and you can run PHP and Java.
As I stated in the comments, GlassFish and Apache Tomcat are Java application servers. In order to serve PHP pages you'll need to install a web server such as Apache HTTP web server. You'll also need to configure Apache to serve PHP files.
Something that you might look into is WAMP (Windows/Apache/MySql/PHP). This offers a simple way to get up and running quickly with little to no configuration.
We have a GWT application which draws some resources from a separate servlet via async javascript. In production this poses no problems as both the producer servlet and the consumer GWT app will reside on the same server, however for development I can't find a way to make this happen as we are head to head with the Same Origin Policy.
As a temporary solution I have the servlet running on Tomcat, and I compile and deploy the GWT app to that same Tomcat instance - this of course works, and it does allow me to attach Eclipse for debugging. However there is the slight problem of the 40 second or so build time for each modification.
We would like to be able to debug via GWT's hosted mode w/ OOPHM - can anybody see a way for us to do this?
Thanks all!
you could use the -noserver option of gwt dev mode, which lets you run your server code with any servlet container.
Maybe you can deploy the producer servlet to Jetty.
http://www.enavigo.com/2008/08/29/deploying-a-web-application-to-jetty/
I think the Jetty home most reside somewhere in the Eclipse directories. A simple file search might help.
Good luck!
If you need just a servlet, why not define it in web.xml and start dev mode as usual?
I'm trying to call a web service in my back end java code when it's
running in hosted mode. Everything loads fine, the GWT RPC call works
and I can see it on the server, then as soon as it tries to call an
external web service (using jax-ws) the jetty falls over with a
Internal Server Error (500).
I have cranked the log all the way up to
ALL but I still don't see any stack traces or cause for this error. I just get one line about the 500 Error with the request header and response.
Does anyone know if the internal jetty keeps a log file somewhere, or
how I can go about debugging what's wrong?
I'm running GWT 1.7 on OS X 10.6.1
Edit: I know that I can use the -noserver option, but I'm genuinely interested in finding out where this thing lives!
From the documentation:
You can also use a real production
server while debugging in hosted mode.
This can be useful if you are adding
GWT to an existing application, or if
your server-side requirements have
become more than the embedded web
server can handle. See this article on
how to use an external server in
hosted mode.
So the simplest solution would be to use the -noserver option and use your own Java server - much less limitations that way, without any drawbacks (that I know of).
If you are using the Google Plugin for Eclipse, it's easily set up in the properties of the project. Detailed information on configuration can be found on the official site.
Edit: you could try bypassing the Hosted Mode TreeLogger, as described here: http://blog.kornr.net/index.php/2009/01/27/gently-asking-the-gwt-hosted-mode-to-not):
Just create a file called
"commons-logging.properties" at the
root of your classpath, and add the
following line:
[to use the Log4j backend]
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger
[to use the JDK14 backend]
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Jdk14Logger
[to use the SimpleLog backend]
org.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog
Edit2: the trunk of GWT now also supports the -logfile parameter to enable file logging, but it probably won't help in this case, since the problem lies in the way the Hosted Mode treats the exceptions, not the way it presents them.
