Re: SuperDevMode Running With GWT 2.6.1 (ant/Command Line)

No, I didn't run accross that nugget and I wish I had. The biggest issues I had were A) coming up with an ant target to run CodeServer and B) figuring out these basic concepts:

 * SuperDevMode completely replaces DevMode.
 * Unlike DevMode, SuperDevMode has nothing to do with actually launching/running your application.
 * There is nothing special you need to do when launching your application (seperately).

That last bit had me baffled the longest because with my setup I had to use a URL different from the default to get DevMode working, and that took me a while to figure out at the time. So with SuperDevMode it took me a LONG time to try just running my server and pointing my web browser at it without any funky parameters like you do with DevMode.

I might create a new question on SO and copy/paste that answer as a "community wiki"; or maybe copy/paste that to my blog, to make it easier to find (given that it's not the accepted answer for that question)

Hello,

I upgraded from GWT 2.6.1 to GWT 2.7 and immediately starting getting reports of my app not launching after being loaded. I was unable to reproduce the issue, so I went back to using GWT 2.6.1 for now. I will try again with 2.7.1 maybe. However, in the mean time, I got REALLY attached to SuperDevMode, or rather not having to manage stale and a fresh versions of my browser. So I really wanted to get SuperDevMode working with GWT 2.6.1. Unfortunately I seem to be one of the few people that prefer not use an IDE to develop, so most of the examples of how to do what I want have been less than helpful. To make things even more interesting, I am using JSON to talk to a Perl server instead of the standard server. I just got it working, so I wanted to share the wealth.

First edit your project.gwt.xml file and add:

  <add-linker name="xsiframe"/>

Second, edit your build.xml file and add something like:

  <target name="sdm" depends="javac" description="starts the superdevmode">
    <java fork="true" failonerror="true" classname="com.google.gwt.dev.codeserver.CodeServer">
      <classpath>
        <pathelement location="src"/>
        <path refid="project.class.path"/>
        <pathelement location="${gwt.sdk}/gwt-codeserver.jar"/>
        <pathelement location="${gwt.sdk}/validation-api-1.0.0.GA.jar" />
        <pathelement location="${gwt.sdk}/validation-api-1.0.0.GA-sources.jar" />
      </classpath>
      <arg value="-src"/>
      <arg value="${basedir}/src"/>
      <arg value="com.myproject.Project"/>
    </java>
  </target>

Third, assuming everything works right, when you ant the sdm target it will provide a URL. If you go to that URL it will give you a bookmarkable URL to start SuperDevMode and another one to stop it. Yes, you really need to at least add the "Dev Mode On" bookmark. After you do that then you can close the tab and probably never visit it again.

Fourth, and this was the hardest part for me to figure out from the information given, is you need to go to the same base URL to run your application that regular DevMode uses. In other words, omit the gwt.codesvr parameter.  In my case that is "http://localhost:3000/app/index.htm", but it will definitely be different for you unless you are running a development Mojolicious server. Your app should load, and then you click your "Dev Mode On" bookmark to recompile and reload. It's a little clunky having to click the button to recompile, but it's a whole lot better than running an old version of a browser.
