GWT with -noserver

Question

I am making a GWT project that uses PHP to connect to a DB2 database. When I compile the project and deploy it on the server (copy the contents of the WAR directory), it works fine, it is obvious that in the hosting mode I am running the SOP problem, since GWT is on port 8888 and the php script is running on port 80.

I am trying to run the -noserver option, but I am missing something. I came back and created a basic sample application from the command line (webApplicationCreator -out / home / mike / gwt / sample1) I edited build.xml to include the -noserver and -port 80 arguments for devmode. I want my application to be hosted in localhost / sample1, so I edited -startupUrl for the whole URL I want to use: http: //localhost/sample1/sample1.html

I compiled (ant), copied the file sample1.html, sample1.css from war to the webserver directory sample1 and (md5) .gwt.rpc, clear.cache.gif, sample1.nocache.js and hosts.html files from the war / directory sample1 in sample1 / sample1, as described in the GWT documentation (the history.html file was not created). Then I run ant devmode from the project directory (/ home / mike / gwt / sample1) I can go to the sample1.html page, but when I click the button to send the name to the server, it returns with

Remote Procedure Call - Failure

Server responses: An error occurred while trying to contact the server. Check your network connection and try again.
