OOPHM plugin for firefox problem.

[dougx]

Just installed the GWT 2.0 MS1 && OOPHM plugin for firefox, and I
can't get it to work in development mode.

The webserver simply sits there and reports:
00:00:02.844 [INFO] Waiting for browser connection to
http://localhost:8080/Demo.html?gwt.hosted=10.12.18.76:9997

This is odd, because I've tried with the chrome and ie plugins as
well, and get the same thing.

I've tried adding 10.12.18.76 and localhost to the list of accepted
servers in the plugin options, but that doesn't seem to do anything...

I've also tried telnet'ing into 10.12.18.76:9997 and the server
reports:
00:02:11.797 [INFO] Connection received from ws211.win2k.intranet.org:
4140

So it seems the server is up and listening; the plugin just isn't
talking to it...?
Anyone had similar troubles?

It used to be the case that the server would start firefox with the
appropriate URL for you, but that didn't always work too well. They
fixed this by removing the attempt to start firefox altogether - you
have to start the browser yourself and point it at the URL you're given.

Seems that because I was trying to switch an existing eclipse project
over to the new version my war/WEB-INF/lib/gwt-servlet.jar was still
the 1.7 version; replacing it with the same file from 2.0 ms1 archive
fixed the problems I was having.

(Well... the browser still doesn't launch automatically, but if you
start it manually it'll actually connect and do debugging, etc. now.)

Kind of lame that doing a project-clean in eclipse doesn't clear and
redeploy those files; and that the browser plugin doesn't seem to
output any kind of debug log / warning that you're being a dork (there
should always be dork warnings... :D); this is a problem that a
looooooooooooooooot of people seem to be running into (according to
the comments here anyway: http://code.google.com/p/google-web-toolkit/wiki/UsingOOPHM)

Still, it's early release. Just glad I got it working!

Hey dougx,

Are you using the Google Plugin for Eclipse? If so, switching the SDK should update the gwt-servlet.jar in your war/WEB-INF/lib folder. However, there is another issue that you'd run into:

I can confirm absolutely that swapping the GWT settings does not alter
the gwt-servlet.jar file on 3 computers I've tested it on (all winxp).

For example, trying to roll back to GWT 1.7 will result in this error
when you attempt to launch hosted mode:
[ERROR] Invalid version number "2.0" passed to external.gwtOnLoad(),
expected "1.6"; your hosted mode bootstrap file may be out of date; if
you are using -noserver try recompiling and redeploying your app

This is again fixed by replacing the gwt-servlet.jar file.

Looks like this might be the plugin eclipse failing to do something,
but I don't see any errors in the logs.

I'd expect something like this, which is what you'd get if you set the
file to read only:
eclipse.buildId=M20090211-1700
java.version=1.6.0_13
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Command-line arguments: -os win32 -ws win32 -arch x86

The issue you've mentioned doesn't seem to be directly related
(although it is also an issue when you swap over to 2.0 ms 1);
cleaning the project (removing all files) and rebuilding fixes any
issues with the nocache.js files in the project for me... but I guess
that's what I'd expect to have to do once I change libraries...

Hm, it does seem that the plugin is throwing an exception here:

Does this exception happen consistently when you switch SDKs? Also, is your war/WEB-INF/lib directory version-controlled?

FWIW, I have seen FF 3.5 crash after "some time". I don't know how to reproduce the problem. The crash reporter is enabled. If there's some info I can glean from the crash reporter or other bread crumbs I'm happy to help.

I think we're talking about different plugins here :). I was referring to the Google Plugin for Eclipse. But, if you do see any crash logs resulting from the GWT Developer Plugin on FireFox 3.5, please do create a new thread and post the information.
