GWT 2.0.0rc2 ::: Unknown argument: -portHosted

[Prashant]

Hi,

I am using GWT 2.0.0rc2 with GAE SDK 1.2.6 on Vista, whenever I try to run or debug the project I am getting following error. I tried creating a fresh project but the problem persists.


Unknown argument: -portHosted
Google Web Toolkit 2.0.0-rc2
DevMode [-noserver] [-port port-number | "auto"] [-whitelist whitelist-string] [-blacklist blacklist-string] [-logdir directory] [-logLevel level] [-gen dir] [-codeServerPort port-number | "auto"] [-server servletContainerLauncher] [-startupUrl url] [-war dir] [-extra dir] [-workDir dir] module[s]

where
  -noserver        Prevents the embedded web server from running
  -port            Specifies the TCP port for the embedded web server (defaults to 8888)
  -whitelist       Allows the user to browse URLs that match the specified regexes (comma or space separated)
  -blacklist       Prevents the user browsing URLs that match the specified regexes (comma or space separated)
  -logdir          Logs to a file in the given directory, as well as graphically
  -logLevel        The level of logging detail: ERROR, WARN, INFO, TRACE, DEBUG, SPAM, or ALL
  -gen             Debugging: causes normally-transient generated types to be saved in the specified directory
  -codeServerPort  Specifies the TCP port for the code server (defaults to 9997)
  -server          Specify a different embedded web server to run (must implement ServletContainerLauncher)
  -startupUrl      Automatically launches the specified URL

and

Please help me out.

I tried updating the plugin using IDE and it said "a newer version is already installed".

As noted in the release notes, "The -portHosted Development Mode flag
has been renamed to -codeServerPort"; and as also noted (well, a bit
implicit I concede), you need to update your Eclipse plug-in by
unzipping the RC2 version (just as you did with the RC1) as there's no
update site for them. (unzip the RC2 *above* the RC1, as it seems the
RC2 distro isn't "complete")

it worked ! thanks.

[Šobis]

I have similar problem. I made new web project and - I'm using GWT 2.0
rc2.

When I try to start, this is what I get in console:
Unknown argument: -style

Google Web Toolkit 2.0.0-rc2
DevMode [-noserver] [-port port-number | "auto"] [-whitelist whitelist-
string] [-blacklist blacklist-string] [-logdir directory] [-logLevel
level] [-gen dir] [-codeServerPort port-number | "auto"] [-server
servletContainerLauncher] [-startupUrl url] [-war dir] [-extra dir] [-

What is wrong - what should I change? I have latest Eclipse plugin...

Thanks for answers.

When you say "the latest Eclipse plugin", does it mean the "RC2"
version linked from http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC
?

If you have a 1.1.2, "official" (i.e. from the update site), version;
it won't work (unless you just create a "Java Application" *.launch
configuration yourself instead of using the plugin's "run as web
application".

Hi

I've just done a completely fresh Eclipse and GWT 2.0 RC2 install
including the new plugin:

1.Extracted eclipse-java-galileo-SR1-win32.zip to C:\Program Files (x86).

2.Ran Eclipse, set up a new workspace workspace at
C:\Users\Paul\Documents\Sandbox\EclipseWorkspace and selected “Use
this as the default and do not ask again.”

3.Then installed Eclipse's Web Standard Tools (WST)

- Help->Install new software.
- Manually added the update url as none was present:
http://download.eclipse.org/releases/galileo/
- Then Web, XML, and Java EE Development -> Eclipse Web Developer Tools
- Restarted Eclipse and then closed it.

4.Then copied gpe-e35-1.2rc1.zip\eclipse\features to C:\Program Files
(x86)\eclipse.

5.Then copied gpe-e35-1.2rc1.zip\eclipse\plugins to C:\Program Files
(x86)\eclipse\plugins

6.Then copied the contents of gwt-2.0.0-rc2.zip to
gpe-e35-1.2rc1.zip\eclipse\plugins

7.Started Eclipse again and used the plugin to create a new project.

- Started the wizard.
- Configured the GWT SDK as C:\Program Files (x86)\eclipse\plugins\gwt-2.0.0-rc2
- Unticked “Use Google App Engine”
- Entered project name etc and clicked finish.

8.Then opened the “Web Application” Run Configuration for the project
and ticked “Automatically select unused port” and clicked Run.

And I get the same error:

Unknown argument: -portHosted

Google Web Toolkit 2.0.0-rc2
DevMode [-noserver] [-port port-number | "auto"] [-whitelist

whitelist-string] [-blacklist blacklist-string] [-logdir directory]

[-logLevel level] [-gen dir] [-codeServerPort port-number | "auto"]
[-server servletContainerLauncher] [-startupUrl url] [-war dir]

[-extra dir] [-workDir dir] module[s]

I assume I must be doing something wrong in my install? Having to
manually copy the SDK took me rather by surprise. I guess its kind of
implicit here, http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC,
but an explicit instruction would have been helpful.

I'm running Vista Business if that makes any difference?

Hi All

I should really know by now, that the Internet is a wonderful, wonderful thing!

On the page I quoted:

http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC

there is a comment, currently second from bottom, on November 23rd by
"a.revolution.ultra.blue", which states, in response to another
comment that has the same problem the people in this tread are having:

--BEGIN---
YES! You CANNOT use the google g-icon "web app run menu", you need a
plain jane java application runner, with main class
com.google.gwt.dev.DevMode??

Make sure you have the usual program arguments for a gwt project; mine
are: -port 7777 -startupUrl / ai.yx.xSeed

I have / set to a welcome servlet in web.xml, and my gwt project is ai.yx.xSeed

If you want to use appengine, you will also need to add the program
arguments and vm arguments I mentioned in the post above. ALSO, if you
do NOT use appengine, leave the working directory at default. If you
DO use appengine, add /war to whatever your default directory is... My
project xBook uses ${workspace_loc:xBook}/war

If you absolutely can't get it to go, just download ms2 from the
deprecated dl page, and you can go ahead and use the old google-plugin
launch configuration.
--ENG--

So, I am now a little further. I have a Java Application Run
Configuration that uses com.google.gwt.dev.DevMode as the Main class
and has the arguments: -port 7777 Gwt2RC2 (my project is called
Gwt2RC2).

However, i still have a problem when I run it:

[ERROR] Unable to find 'Gwt2RC2.gwt.xml' on your classpath; could be a
typo, or maybe you forgot to include a classpath entry for source?

I've tried fiddling with the classpath and source settings of the Run
Configuration, but so far nothing's worked. Does anyone know what I'm
doing wrong?

Hi

I've got a bit further....

I needed to fully qualify my module name, so I now have:

-port 7777 uk.co.marauder.gwt2rc2.Gwt2RC2

and I can start the server and get the HTML part of the web page up,
however I get an error on the Gwt2RC2 (FF) tab of the GWT Development
Module:

[TRACE] Finding entry point classes
[ERROR] Unable to find type 'uk.co.marauder.gwt2rc2.client.Gwt2RC2'

'uk.co.marauder.gwt2rc2.client.Gwt2RC2' is really what you meant

I've tried adding war\WEB-INF\classes to my Run Configuration class
path, but that hasn't worked.

Any ideas?

Sorry for the iterative approach this morning, but I expected to be
stuck at each hurdle.

1) Why are you using 1.2rc1? it won't work with GWT 2.0.0 RC2 wrt the -
portHosted vs. -codeServerPort naming change.
2) Why not just unzip it in C:\Program Files (x86)\eclipse\dropins as
you're told to do?

Why are you putting it within your eclipse install?

See above: you have to use the RC2 version of the plugin with the RC2
version of GWT.

There you go. I was obviously suffering brain fade and really not
paying attention. Thank you for pointing that out.

Go easy! :-)

...because the first time i tried it, it didn't work.

Seems to work perfectly now. It may well have been due to me having
the wrong plugin.

Was fighting int he dark. I'm no eclipse expert and that's where it
seemed to be in the previous plugin. I've now moved it.

Thanks! :-)

All workign now. Thanks!

I was testing the GWT 2 RC2 and everything was ok, untill it stoped to word with all my

That looks like a bug in your code (in AppTeste.java, line 53; which
produces a NullPointerException)

[Gerhard Davids]

Hey, what did you do at this point to get it working?
Your steps up to now has been very valuable.

My run config is now a normal java config instead of the GWT plugin's
config.
I'm getting the following in my Dev Mode when I hit the "Default
Browser" button :

Unable to find type 'com.curasoftware.assessor.client.Assessor'
Check that the type name 'com.curasoftware.assessor.client.Assessor'

is really what you meant

Hint: Check that your classpath includes all required source roots

Now the string the error quotes is my Entry point class.
Im at a loss.

I could simply go to m2 and work from it but there are some fixes in
RC2 that I urgently need to investigate.

Peace
Gerhard

Are you currently using GWT 2.0 RC2? If so, why not use the Web Application Launch Configuration? As long as your application has a war directory, the issue with the incorrect addition of the -style argument will not occur.

As an FYI, to get your Java launch configuration working, you need to add your project's source folders to your launch configuration's classpath.

[Gerhard Davids]

Hi thanks for the response.

I am using GWT 2.0 RC2.
When using the web application launch configuration i get the
following still >

"Unknown argument: -style
Google Web Toolkit 2.0.0-rc2"

I am using a fresh eclipse 3.5 that i first installed the rc 1 plugin
which i then deleted in favor of the RC2 plugin on a win xp sp3
machine.

As far as the normal launch config goes : I still get the dev mode
popping up and directing me to http://localhost:8888/index.jsp?gwt.codesvr=xxx.xxx.xxx.xxx
which loads the html but then fails with the error previously posted.

Still no luck.

I feel very stupid right now :S

It seems my eclipse failed to properly uninstall the plugin from RC1.
I went and manually cleared the plugins from galileo and dumped the
RC2 into the dropins again.

It all works now. I'm sorry for causing a fuss.
Rajeev, thanks again for assisting me.
Regards
Gerhard.
