Re: UI Binder bugs - maybe config issue on my side(?)

[Jason Parekh]

Peter,

Also, would you mind downloading a fresh copy of Eclipse (with a new
workspace) for testing purposes?  I imported your project, and the
@UiFields are not marked as errors for me.  If a fresh Eclipse works,
it'll help in debugging whether it's a system configuration issue or
an Eclipse configuration issue.

Thanks,
jason

So once you download the two URLs you've already listed, click on

Yikes, didn't realize Eclipse hangs as it tries to retrieve the file.

Re: GWT 2.0 maven plugin and eclipse plugin

[Jason Parekh]

Hi,

The presented URLs are discovered a couple of ways:
1) Your war folder contains JSP and HTML files as direct children
2) You add the -startupUrl  argument when launching DevMode, where
 can be an absolute URL (in which case the gwt.codesvr parameter will
not be generate), or a URL path relative to the root of the war folder.

Re: Co-existing 1.7.1 projects and 2.0 projects

[Jason Parekh]

Hi Pieter,

The actual Eclipse plugin supports all versions of GWT (so no downgrading
required there).

What you'll need to do is:

- Make sure GWT 1.7.1 SDK is installed.  In Eclipse, go to Window >
Preferences > Google > Web Toolkit.  If you see 1.7.1 and 2.0.0 there,
great!  If not, you can download GWT 1.7.1 SDK from
http://code.google.com/webtoolkit/versions.html , extract it somewhere, and
click the "Add" button in the dialog.

- Make sure the GWT 1.7.1-based project is using the GWT 1.7.1 SDK.  Right
click on the project, go to Properties > Google > Web Toolkit, and you can
"Use specific SDK".

After these changes are made, you can launch your app again, and it should
work as it did before.  (If it does not, try clearing your browser cache
and/or a clean build of the project.)

Hope this helps,
jason

Re: can not set breakpoint

[Jason Parekh]

Hi Canal,

What version of Java are you running?
Could you try on a simple project (perhaps the default app created by the
wizard)?
I'm assuming the breakpoints do not show the checkmark on top of them (when
the debugger is connected)?

Re: gwt.xml and JUnit with Google Plugin for Eclipse (GWT 2.0.0 in Eclipse 3.5.1.M20090917-0800 on Mac OS X 10.5.8)

[Jason Parekh]

Looks like the value returned from getModuleName isn't valid.  It should
return a fully-qualified module name, for example "com.example.MyModule".

Could you paste your .gwt.xml and the getModuleName implementation from your
GWTTestCase subclass?  Also, which package does the .gwt.xml file live in?

Re: How to add unit test to GWT/AppEngine project created by Eclipse

[Jason Parekh]

First ensure the "test" directory is a source folder:  right-click the
directory, go to "Build Path", and select "Use as source folder".  Next,
populate this with unit tests like usual.  You'll be able to right-click and
select "Run As > GWT JUnit test" after that.

If you want to run these from the command-line, your best bet is probably
create a new dummy project with webAppCreator and copy the relevant parts of
the build.xml test target into a build.xml for your project.

Re: Spring-Eclipse-Hosted Mode

[Jason Parekh]

Hi,

There are a few workarounds for your problems..  Longer term, we're hoping
to improve the current issues with dependent projects.

Issue #1:  You'll likely have to separate your backend project into a
backend project and a shared project.  See
http://code.google.com/p/gwt-client-server-dev-env/ for an example layout
(note these guys use an ant script to build.  See below on linked source
folders to still be able to build within Eclipse).
Issue #2:  You'll need to include the source into the JAR.  I'm not sure how
to do this in Eclipse, hopefully there's an option.  Alternatively, in the
GWT project, you can have a linked source folder that points to your shared
project.

Hope this helps,
jason

Re: eclipse plugin - user define composites

[Jason Parekh]

Hi Brian,

That definitely sounds like a bug.  What is the package name, class name,
and inheritance hierarchy for these custom composites that don't show up?
 Would you be able to send your project or a smaller project showing the
bug?

Also, it'll be better tracking this bug in the issue tracker.  Could you
open an issue with the above information at
http://code.google.com/p/google-web-toolkit/issues/list ?

Thanks!

Re: Google Plugin for Eclipse 1.3 is now available

[Jason Parekh]

Hi Simon,

Could you go to "Run > Run Configurations...", click on your launch
configuration on the left, and then click on the "Arguments" tab.  What do
you see as the "Program arguments:"?  Particularly, what is the value for
the "-war" argument?

If it not your "target/-", try changing it and
re-launching.  If it is, we'll have to look a bit deeper.

Thanks for finding this issue, Simon.

Please see http://code.google.com/p/google-web-toolkit/issues/detail?id=4761,
which includes the workaround that you've already found :)

That definitely seems like a bug in the slash-escaping logic.  I've created

issue.  Mind if we continue the discussion there?

Re: Bug in eclipse plugin with UiBinder define in an inner class

[Jason Parekh]

Hi Bilousme,

I've opened a bug at
http://code.google.com/p/google-web-toolkit/issues/list?thanks=4764 to track
this issue.

If you're using GPE 1.3.0, another workaround is to change the severity of
the UiBinder validation errors.  This can be found in the Eclipse
preferences > Google.

Thanks!

I recommend the Android lists--some members of the Android browser
team monitor those lists (I don't think any of them monitor this
list).  Also, filing bugs on the tracker is always recommended.

As for trying out cupcake, you can build an emulator running Cupcake
with the instructions at http://source.android.com/download .

Nope, sorry.

I know it's a lot of work, but building from the repo may be a good
idea (there's been a lot of change since early January).

You're likely getting stuck in the Eclipse's dependency checks.  Check

Re: how to make gwt eclipse plugin compiler see other projects

[Jason Parekh]

Hey Joe,

It looks like you're hitting an issue where the Eclipse plugin does
not include a dependent project's compiled classes into the packaged
WAR that is deployed to the server.  We're aware of the issue and it
will be fixed in a future release.

There are a couple workarounds, one of which you've tried (package the
dependent project into a JAR, and statically link that into the main
project).  The other is to set the dependent project's output
directory to the main project's output directory.  When the hosted
mode server runs (or the app engine tools upload to app engine), all
classes in this directory will be included (including the dependent
project's).

Re: how to make gwt eclipse plugin compiler see other projects

[Jason Parekh]

BTW, another related issue when dealing with dependent projects is
ensuring GWT inheritance is defined properly.

For example, imagine project A has a GWT module MA and project B has a
GWT module MB.  If the types in MA refer to the types in MB then MA
must inherit from MB.

To properly configure, please ensure that:
- the Java project A depends on the Java project B in Eclipse, and
- MA's XML file declares its inheritance of MB

Re: Error downloading Google Plugin for Eclipse

[Jason Parekh]

Hey,

Which version of Eclipse are you using?  Also, which update site did
you try to install from?

Thanks,
jason

Re: Eclipse Run Configurations confusion: GWTCompiler vs. Compiler

[Jason Parekh]

Hi William,

Have you installed the Google Plugin for Eclipse?  Using that, you can
compile your GWT project with the red G icon in the toolbar (or
alternatively, right-click on project > Google > GWT compile).

Re: GEP, war/WEB-INF/lib, and source control

[Jason Parekh]

Hey Isaac,

Good question.  You can go either route:

- If you do not check them in, you'll get a warning in Eclipse.  Doing
a quick fix (select it and ctrl+1) on that warning will copy the
installed SDK's JARs over to your lib directory.

- If you do check them in, like you mentioned, there's a chance for
some conflicts.  In this case, you should also get a warning
mentioning the SDK's JARs mismatch the war/WEB-INF/lib JARs, and there
is a quick fix to copy from SDK to lib.

Re: Create a file

[Jason Parekh]

Oh sorry, forgot to mention that your project is also set up for
deploying to App Engine, and that is why this restriction is being
placed on you.  If you have no intent of using App Engine, then you
can remove that support from your project:  Right click on your
project, go to "Properties", expand "Google" on the left, click on
"App Engine", and then uncheck the "Use Google App Engine" checkbox.

Re: Eclipse plugin - empty src folder

[Jason Parekh]

Hi Maarten,

What is the full path to this project?  Are there any characters in
the path that could be revealing bugs in the plugin?

Also, which View are using to look at the source folder?  Can you
check to see if the Navigator view (Window > Show view > Navigator)
shows the files?

After the web app project is created, can you right-click on the
source folder and add a new class?  Does that show up?  Can you make
sure the View is not filtered? (You can do this by clicking the
down-facing arrow in the upper-right corner of the View, and selecting
"Filters".)

Do other projects work ok? (e.g. A regular Java project)

Thanks,
jason

Re: how to install gwt in ubuntu

[Jason Parekh]

If you're an Eclipse user, I'd suggest going the Google Plugin for
Eclipse route:  install Eclipse via the package manager (e.g.,
synaptics for a UI, or apt-get for command-line), and then install the
Google Plugin for Eclipse via
http://code.google.com/eclipse/docs/getting_started.html (which will
pull in the GWT SDK).

Re: Problem creating a new Web Application Project in Eclipse using the GWT eclipse plugin

[Jason Parekh]

Hi Roshan,

Sounds like the plugin installation didn't go as smoothly as it should
have.  Can you try uninstalling the Google plugins, shutting down
Eclipse, launching Eclipse, and re-installing?  If that problem still
persists, we can investigate further.

Thanks,
jason

Re: Error while using dependent project.

[Jason Parekh]

Hi Shishir,

Another option is to set the output directory of 'Model' to
GwtProject/war/WEB-INF/classes, see
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/951499c5773693c9/0ae1a71ac2e4d3f1?#0ae1a71ac2e4d3f1
for more details.  Not nearly as clean as proper dependent project
support, but we're working on that :)

Good find, definitely looks like this flow could be improved.  If you

The Google Plugin for Eclipse currently doesn't support this type of

Re: Eclipse project files are missing from the GWT samples

[Jason Parekh]

Hi Jim, thanks for pointing this out.
I've opened a bug at
http://code.google.com/p/google-web-toolkit/issues/detail?id=3732 .

A workaround (as mentioned in the bug) is:

Create samples/Showcase/war/WEB-INF/web.xml containing:

--

http://java.sun.com/dtd/web-app_2_3.dtd";>


--

and then follow the instructions at
http://code.google.com/eclipse/docs/existingprojects.html

Re: Data base exception in GWT

[Jason Parekh]

Hi Subbu,
Google App Engine has a whitelist of classes that are allowed for use, and
unfortunately ut seems like InitialContext didn't make the cut.  Please see
http://code.google.com/appengine/docs/java/runtime.html#The_Sandbox and the
section after it.

Also, Google App Engine questions are better answered in its Google Group
at http://groups.google.com/group/google-appengine-java

The Google Plugin for Eclipse doesn't properly support project dependencies

Are you using the Google Plugin for Eclipse?  How are your tests structured
with relation to the GWT application (for example, what are the paths to
each of these, are they in separate projects, etc.)?

Re: Unit testing GWT and App Engine in Eclipse

[Jason Parekh]

Hi Johan,
I don't think there are any frameworks that can let you test a round-trip
between the two.  Instead, you'll likely want to test each side individually
(see http://code.google.com/appengine/docs/java/howto/unittesting.html for
App Engine junit testing).

If you're using the Eclipse plugin, I have a sample project that tests an
App Engine project, see
http://www.wuala.com/jasonparekh/Public/google/beingTested.zip/ .

Hope this helps,
jason

Re: Receiving "Plugin failed to connect to hosted mode server 127.0.0.1:9997" Error

[Jason Parekh]

Hi Julian,

What operating system are you running?

You can try a couple things that have worked for others in the past:
- Instead of 127.0.0.1:9997, try localhost:9997
- Add "-bindAddress *0.0.0.0" to your program arguments in the launch
configuration.  This lives at Debug > Debug configurations... > Select your
launch config on the left > Arguments tab.  Just add "-bindAddress 0.0.0.0"
in the beginning before all the other arguments.  This makes it listen on
all network adapters, so another machine on your network could connect to
you.*

Re: com.google.gwt.eclipse.core.gwtNature

[Jason Parekh]

Hi Jim,

Sorry, the Google Plugin for Eclipse's source code is not available.  You
might be able to achieve what you want by looking at a sample GWT project's
.project file, which will contain the GWT project nature ID.  You should be
able to add this to your project description.

I'm curious, what is it that you're adding this into?

Oh, I missed the subject of the thread.  It looks like you've already found
the ID of the GWT nature.  Try adding that to your array of Strings which is
being passed to setNatureIds.

Re: Problems with Eclipse Plugin

[Jason Parekh]

Hey Moe,

You can fix this by re-adding the SDKs in the preferences.

Go to Eclipse > Preferences.  Choose Google > Web Toolkit on the left.
 Remove the existing SDK, and re-add it at the new path.  I believe the path
will be something like:
 PATH_TO_ECLIPSE/plugins/com.google.gwt.eclipse.sdkbundle/gwt-2.0.3.  You
can do the same thing for App Engine as well.

Re: [Newbie] "java.net.SocketException: Invalid argument" when running devmode

[Jason Parekh]

Hi Chihab,

It looks like there are general issues with your configuration when
listening on sockets.

Given you're on Linux, I can't imagine it to be permission issues.  Have you
tried rebooting?  Do you know if any of your other apps successfully listen
on a port?  Could you try a quick Java sample to listen on a port?  For
example
http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html.

Re: [Newbie] "java.net.SocketException: Invalid argument" when running devmode

[Jason Parekh]

Hi Chihab,

Rajeev brought up a good point.  It could potentially be an IPV6 issue with
Sun's sockets. You could try seting the networking property:
java.net.preferIPv4Stack=true
as documented here:

As you've found, dependent projects are a very rough area in GPE.  One
solution that should work for you is: in your main project, use "Link
Source" to add your widget project's source folders.

Sorry -- that's a bug on me.  The current feature allows you to change
argument values, but as you've found, removing arguments altogether won't
stick.

"-remoteUI" allows the DevMode view inside Eclipse to be the UI for DevMode
instead of the Swing-based UI in the GWT SDK.  Regarding removing this
argument leading to a working application:  You may have hit a bug we
haven't seen before -- can you try the below and see if that's the case?  If
so, we can dig a bit deeper on that issue (assuming your other issues are
taken care of.)

Create a new plain "Java application" launch configuration.  For each of the
tabs "Main", "Arguments", and "Classpath", copy the values from your
existing "Web Application" launch configuration.  In this new "Java
application" launch configuration, you can remove the "-remoteUI" and see if
things work.

Also, try deleting your existing "Web Application" launch configuration and
re-running your main project.  That will create a new launch configuration
from scratch with the defaults, which should get you back into a working
state (assuming you were in a working state before, which it sounds like you
were at some point.)

Nope, not at all :)  Sorry about your troubles in these couple rough areas,
hopefully we can get you back on a working path.  And as always, thanks for
letting us know which areas need improvement.

Re: -port keeps disappearing

[Jason Parekh]

Hi,

The "-port" argument is for specifying the port of the embedded server.  In
your case, you're running an external server, so the "-port" is not needed,
and that's why it is getting removed.

 Anyone else get this? Any way to make it 'stick'? Is it a bug in the

Re: GWT plugin for eclipse install problem

Hey,

Could you try starting with a fresh Eclipse for Java EE and run Eclipse with
admin privileges?  I recall some folks having weird issues on Windows 7 that
were resolved by doing this.  If it doesn't work, we can dig into your
configuration and log files to figure out what's going wrong.

Yup, I meant install a new Eclipse (as an administrator) and then install

Re: Eclipse GWT Plug In installation problem

[Jason Parekh]

We've heard of similar strange behavior on Windows machines, and folks seem
to resolve it by installing and running Eclipse as an administrator.

We've also seen similar behavior on Linux that is caused by
https://bugs.eclipse.org/bugs/show_bug.cgi?id=281510 .  The workaround for
this is to download the Eclipse zip file and just install it for your user.

Re: Importing Contacts MVP example into Eclipse

Hey Kevin,

The Contacts.zip file actually has the Eclipse project metadata included
(the .project and .classpath files.)  What you can do extract that zip file,
in Eclipse go to File > Import > Existing projects, and point it to the
extracted directory.

Re: Problems running GWT app using Eclipse plugin

[Jason Parekh]

Hi Fabricio,

Could you try this:

- Run your new, empty GWT project via Eclipse, then go to its Debug view.
- You should see a line in the Debug view with something like:
"/usr/lib/.../java (...)".
- Right-click on this, go to Properties, and copy+paste the Command Line
into a reply.

Re: Problem with eclipse plugin.

Those versions are obsolete (including RC2).  The latest stable version of
our plugin is GPE 1.3.3, which is available via our update site, see

The bulk of GPE 1.4.0 M1 are features to integrate with STS 2.3.3 M1.  Since
that version of STS is built on Eclipse 3.5, we did not release an Eclipse
3.6 version of GPE 1.4.0 M1.   GPE 1.4.0 M2 will include Eclipse 3.6
support, and should be coming shortly.

If you're wanting to use Eclipse 3.6, I'd recommend jumping to Eclipse 3.6 +
GPE 1.3.3, and then switching to 1.4.0 M2 when it arrives.

I've never used Pyjamas, but you can launch dev mode with the "-noserver"

Re: New open source eclipse plugin for UiBinder validation

[Jason Parekh]

Hey Gal,

Very cool!  GPE doesn't expose any extension points, but you should be able
to add your autocompletion proposals by hooking into WST's autocompletion
framework (we
subclass 
org.eclipse.wst.xml.ui.internal.contentassist.XMLContentAssistProcessor).

Hope that helps,

Hi Bálint,

Is the checkbox "Launch and deploy from this directory" checked? (It is

Also, is this a new project or your existing project?

Re: Google Plugin for Eclipse 3.6 + Different war directory

[Jason Parekh]

Hi Bálint,

Oh, ok.  In that case, the only time that GPE copies files to the WAR
directory specified  by "-war" argument is if you're using the Java EE
support in Eclipse.  Can you make sure your Eclipse 3.6 includes Java EE
support? (Was it the Eclipse for Java EE 3.6 that you downloaded?)  Also,
are you re-using your existing workspace from Eclipse 3.5?  If not, I wonder
if there are differences between how the project was setup in Eclipse 3.5
and how it is setup in Eclipse 3.6?

Google Plugin for Eclipse 1.4 M2

[Jason Parekh]

Excited about Google Web Toolkit 2.1
M2?
 There's also a new Google Plugin for Eclipse 1.4 M2 to go along with it.
 Check out the new Speed
Tracerintegration -- a
simple toolbar button will launch Chrome and Speed Tracer
to help you identify and fix performance problems in your web apps.  Once
you find an issue, you can click on a link in Speed Tracer to jump directly
to that line of code in Eclipse.  There are also many bug fixes, and smaller
features like the ability to double-click URLs in the Development Mode view
or the ability to halt an in-progress Deploy to App Engine or GWT compile.

We recommend you install this on a clean Eclipse installation.  Here are the
update sites:

   - Eclipse Helios (3.6):
   http://google-web-toolkit.googlecode.com/svn/2.1.0.M2/eclipse/plugin/3.6
   - Eclipse Galileo (3.5):
   http://google-web-toolkit.googlecode.com/svn/2.1.0.M2/eclipse/plugin/3.5
   - Eclipse Ganymede (3.4):
   http://google-web-toolkit.googlecode.com/svn/2.1.0.M2/eclipse/plugin/3.4
   - Eclipse Europa (3.3):
   http://google-web-toolkit.googlecode.com/svn/2.1.0.M2/eclipse/plugin/3.6

Enjoy!

Re: GWT compile modules into specific directory?

[Jason Parekh]

I don't think there is any built-in way to do this, but you may be able to
write a custom Linker to do this (see http://development.lombardi.com/?p=29).

Re: Using project dependency in eclipse

[Jason Parekh]

Hi Chandra,
Unfortunately there isn't an easy way to achieve this right now.  There are
two approaches you can take:
- Set the output directory of the non-GWT project to
/somewhere/somewhere/pathToGwtProject/war/WEB-INF/classes, or
- Package the non-GWT project into a JAR, and place that into
/somewhere/somewhere/pathToGwtProject/war/WEB-INF/lib

Re: Google plugin for Eclipse 3.5 Galileo

[Jason Parekh]

Thanks for response Brett.  Unfortunately, the plugin uses many internal
Eclipse APIs (for example, for our JSNI integration into the editor) and we
can't assume the next version will remain compatible.
Anyway, we're working on
getting 3.5 support out in the next couple/few weeks.

Re: How will you announce the release of the plugin for Galileo?

[Jason Parekh]

Hey,
Our Eclipse plugin has an update notification that appears in the lower-left
corner of the window (when a newer version is available).  If you want to be
safe, you can also star
http://code.google.com/p/google-web-toolkit/issues/detail?id=3789&q=3.5%20eclipseto
be notified of updates (we will close the bug on release).

If we do a blog post, it will likely appear on the GWT blog (
http://googlewebtoolkit.blogspot.com).

Re: GWT 1.5 to 1.6: App won't work in Hosted Mode

[Jason Parekh]

Hi Sky,
What exactly do you see in the hosted mode browser?  Just the HTML content
(with GWT widgets missing)?

I'd suggest a couple things to reduce where we search for the problem:
- Can you try creating a new GWT app from the wizard and see if it loads in
the hosted mode browser?  Can you try a breakpoint in this module's
onModuleLoad?
- Can you look at the error log (Ctrl-3, then type error log).  See any
errors there that may pertain to the problem?

Strange about not hitting the breakpoint with this simple project.  We've
seen this issue with JDK 1.6.0_14, are you running that version?  Try
downgrading to 1.6.0_13.  See:

http://code.google.com/p/google-web-toolkit/issues/detail?id=3724

for more details.

Sorry, I'm not very familiar with the changes from 1.5 to 1.6 (perhaps
someone more knowledgeable could chime in?), but I wouldn't expect your
changes got you into the current state.

Assuming you're running JDK 1.6.0_14, could you try setting the breakpoint
again after downgrading?  Hopefully it'll break, and you can step through
your code to gather more useful data.

How big is your application?  Would it be feasible to try the GWT 1.5 -> 1.6
process again, except move your code in smaller chunks?

Re: Add external java project to GWT project in Eclipse

[Jason Parekh]

Hi Martin,
You may try using the link source option, as suggested by the thread at
http://groups.google.com/group/google-appengine-java/browse_thread/thread/1908b3bedf954b75/ca0370ae3ae5a394?lnk=raot.
 If that doesn't work, you could set the output directory of your
dependencies to be the GWT output folder.

Re: Eclipse plugin update

[Jason Parekh]

Hmm, have you accidentally placed checkmarks in any other plugins besides
Google Plugin for Eclipse?  The Google Plugin for Eclipse doesn't depend on
any of the plugins you mentioned.
Could you try clicking the "Available software" tab, and the "Manage sites"
button, and uncheck every update site but the Google update site?

Re: Add external java project to GWT project in Eclipse

Hi Martin,
For the "Linked folder location," ensure you have the trailing "src"
included.

Re: Common parent project - How?

[Jason Parekh]

Hey,
I believe the easiest way to accomplish this is instead of using the project
dependencies, use the linked source feature.  For each of your child
projects, go to Properties > Java Build Path > Source > Link Source, and set
the location to your core project's "src" directory (and the name to
whatever you like).

Yup, it should.  In your child project, you'll have the code of both
projects.

In the GWT Compile dialog, you can expand the "Advanced" section at the

Hi Muhannad,
Would you be okay with debugging via Jetty?  If so, right-click on your
project and select Debug As > Web application, and it should just work.

If this doesn't, please paste the detailed errors in your reply.

Re: Google plugin for eclipse3.4 launches GWT hosted mode with deprecated GWTShell

[Jason Parekh]

Hey Ron,
Please see this bug and star it (we use stars to gauge the importance of
certain non-critical bugs):
http://code.google.com/p/google-web-toolkit/issues/detail?id=3877

Also, you should be able to create the war as a linked folder in the
upcoming GPE 1.1:
http://code.google.com/p/google-web-toolkit/issues/detail?id=3692

Finally, you may be able to try using a symlink right now, if your platform
supports these.

Hope this helps,
jason

You can create a new Run configuration to run your tests.  Open Run > Run

configure the created configuration to point to your test cases.

No, unfortunately you don't have file system access on App Engine.  You can
store data in databases, but you won't have any file handlers to that data.

Re: gwt 1.7 app - blank page in ie7, safari

[Jason Parekh]

Hey Peter,

Not sure if this will help, but could you try clearing the cache in each of
your browsers?  Have you tried viewing the source in IE7 and Safari?

Re: Google plgin 64 bit support

[Jason Parekh]

The Google Plugin does support 64-bit, but right now GWT still requires a
32-bit JRE.

What you can do is go to your launch configuration (Run -> Run
configurations, and find the Web Application launch config) and update its
JRE to a 32-bit version.

Re: gwt 1.7 app - blank page in ie7, safari

[Jason Parekh]

Is your nocache.js file in the same directory as your HTML?  I believe so
since it works on some of the browsers, but just wanted to make sure since
the default layout places this into a module-specific directory.

Sorry, I'm not familiar enough with GWT to give you better support.

Hey Peter,

Could you try changing your  tag to include the attribute:
type="text/javascript":
