To deploy GWT1.6 app on my own local web server issue

[bencoder]

Dear all

I use EasyPHP, a kind of WAMP, to build my own local server (http://
localhost:80/).
Then, I create a application using Eclipse with GWT1.6 plug at
localhost/myAPP directory.
This application, myAPP, needs to request JSON data from json.php file
which locates at localhost/json directory.

I think I have to disable the embedded Tomcat server.
Hence, I open Run->Open Run Dialog... in Eclipse, and add -noserver
and -port 80 in Program arguments on Argrments tab.

After that, I run the app in host mode. But there is nothing to
appear, i.e. the http://localhost/myAPP.html is NOT found.
I have tried to add -startupUrl /myAPP.html in Program arguments, the
problem is still here.

Do any flags that I missed need to be added in Program arguments?


BR,
bencoder

Re: Problems with ImageBundle in IE8 when not in compatibility mode

[Alex Epshteyn]

BE CAREFUL when copying code from this page - Thomas Broyer's comment
has an error.

The correct meta tag to add is



be sure the first attribute is http-equiv, not name!

(wasted 20 minutes on this)

I can confirm that this tag fixes the problem with ImabeBundle.

Be sure to read http://msdn.microsoft.com/en-us/library/cc288325.aspx
for more info.  As it says, this meta tag must appear before any
element in in the  except  and/or other  tags.
(This makes sense, because the browser needs to process this tag prior
to interpreting the stylesheets).

Re: @gwt.TypeArgs gwt 1.6 specification documentation

[Blessed Geek]

I suppose the actual word is "hearsay" rather than "heresay".
Furthering my engagement in trivial semantics, so my other question
is, begging your pardon for indulging in technical jargon purism,

Is GWT "RPC" can really be called "RPC". If it can be called RPC, then
every time I time into my browser "http: //
something.something.something" I would be engaging in RPC, wouldn't I?

Perhaps, it is more accurately called Origin Servlet Call, because
unlike other/traditional RPC which could be authenticated call to
execute "real procedures" in "out-of-domain" servers, GWT RPC is
restricted to the origin server between web page client and origin
server.

Anyone has an opinion why GWT RPC could be called RPC without allowing
calling my normal use of browser loading from an http servlet/jsp
being called RPC.

@gwt.TypeArgs gwt 1.6 specification documentation

[Blessed Geek]

Dear GWT team,

This may seem trivial but I think even if it is worth just a paragraph
or two, you should document the new requirements rather than just
referring to "unlike pre-gwt1.5, you have to used parameterised types"
in blogs and discussions.

Having proper documentation makes it "professional" too. I find it
difficult to ascertain the precise requirement when I have to google-
search for "@gwt.TypeArgs gwt 1.6 specification" and finding none but
some heresay/heresy from blogs and discussions.

Even your "what's new" says:
@gwt.TypeArgs pre-1.5 has been deprecated but unbelievably and
unacceptably give examples on how to use @gwt.TypeArgs using the
pre-1.5 patterns.

Re: i need help regarding linking two pages

[Jim]

The following is an example I use in GWT mail:

// Add a click handler that displays a ContactPopup when it is
clicked.
link.addClickHandler(new ClickHandler() { //Similar to Your 
login
page
public void onClick(ClickEvent event) {
mailApp.removeRightPanelWidgets();

if (contactInput == null) {
contactInput = new ContactInput(); 
//ContactInput extends
Composite. That is similiar to your Welcome page
}
mailApp.addWidgetIntoRightPanel(contactInput);  
//Where do you put
your Welcome page.

//You
don't need the following code if there is no RPC
ContactPK contactPK = 
(ContactPK)contact.getPrimaryKey();
mailService.getContact(contactPK, new 
AsyncCallback() {

public void onFailure(Throwable caught) 
{
caught.printStackTrace();
}

public void onSuccess(Contact result) {
contactInput.setContact(result);
}
});
}
});

I've posted a screenshot of the current directory tree:

Part of the problem is that these are under source control and are in
development by a number of people who aren't going to have the same
absolute path to the workspace.

Yeah, I can make the IDE happy very easily, but I've been unable to
find decent documentation on how to define import/dependency rules for
GWT.

Re: Getting started with gwt 1.6 and Intellij 8

[Jim]

1. go to http://www.eclipse.org/downloads/ to download the latest
version of Eclipse. I recommend "Eclipse IDE for Java EE Developers".
2. follow http://code.google.com/eclipse/docs/getting_started.html to
install Google Eclipse Plugin.
3. Use Google Eclipse Plugin to create a simple application with RPC,
which just take you less than 10 minutes.
4. Or You can download the GWT mail from http://www.gwtorm.com/gwtMail.jsp.
It is a RPC-database application modified from the distributed Google
Mail Application.

There are two main projects. One is a big ol' database, which is all
regular Java. The second is a GWT project that serves as a front-end
to the database. The GWT front-end makes requests to the database
through object streams over sockets, and the objects they send back
and forth need to be instances of shared classes.

The DB core does not know about the front-end GUI stuff, and vice
versa.

Re: SIGSEGV in Ubuntu java 6 out the Wazoo!

OpenJDK worked fine for me.

Also, the newer Sun JDKs work fine too - there's
instructionsaround on how
to convert the Sun package into a debian package.

sudo apt-get install java-package
fakeroot make-jpkg .bin
sudo dpkg -i sun-*.deb
sudo update-alternatives --config java

SIGSEGV in Ubuntu java 6 out the Wazoo!

[Alyxandor]

Hey all,

I've been having a slight problem plaguing me of late, and thought to
post this solution for anyone else experiencing the same issue.
There's already a few bugs filed for variations of this, but they're a
little different, on older builds of GWT, so rather than doing +1 on
an old bug report, I thought I'd post on a fresh thread here in case
anyone searches this forum for the problem.

The server is running at http://localhost:7711/

Getting started with gwt 1.6 and Intellij 8

[Rakesh]

hi all,

I'm trying to learn GWT (well Ext GWT top be precise) and have lots of
issues using Intellij.

Firstly, I purchased a book but the examples are based on Eclipse. I'm
trying to translate for Intellij but running into issues the main one
being that Intellij doesn't seem to want to create all the directories
for you. There is a demo on the Jet brains site but its out of date as
the GWT Studio plug in has been deprecated. The new 'facet' system
doesn't create a sample app. I did find a menu item when I created a
new gwt project that said 'Sample App' but it said i needed version
1.5 of GWT or later but I am using 1.6

To top it all, I saw posts by the Jetbrains people to say 'proper'
support will be available in Intellij 9!!!

Bottom line, is it easier to just use Eclipse? Or is there some
staright forward resource out there which will show me how to create a
gwt app in Intellij 8?

Frustrated!!!

Re: Something is worong with my app in GWT 1.6

[Alyxandor]

Like dean said, just getting your php scripts present won't let you
run php scripts in hosted mode.  Even if you deploy to a php-enabled
server, requesting .php returns text, namely, the php source.

If you don't want to run caucho, you could try another somewhat
underhanded approach...  Use the Google plugin with appengine; even if
you can't / don't want to upload to appengine, it gives you the power
of UrlFetch, which lets you tell the server to request files from
somewhere else {namely, your production php server}, and send them
back with whatever content type you want.  You'll have to build a
servlet which you can put at serverscript/server.php, which takes all
of the parameters you want to send your real php, use UrlFetch to send
those parameters to your php server, and return the results {text,
xml, whatever} back to your client side using RPC.  Actually, so long
as you want only want text from your php, you can skip RPC and use
HttpRequest.  It's kind of like using cURL for Java ;-)

If you aren't familiar with servlets, just google: "appengine
UrlFetch"...

Re: GWT Hibernate issue

[Raul]

Hi Jim

Thanks for your reply.

I want to mention that I have already spent a lot of energy in
configuring hibernate. So wont wanna go for Leeonsoft for the time
being.

The main problem I am getting now is:



INFO org.hibernate.
impl.SessionFactoryObjectFactory - Not binding factory to JNDI, no
JNDI name configured
java.lang.UnsupportedOperationException:

at org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection

at
org.hibernate.connection.DatasourceConnectionProvider.getConnection
(DatasourceConnectionProvider.java:89)



Well I think if I get a clue for this I will be a step ahead...

Re: Eclipse & GWT: How to include source from other projects?

[Alyxandor]

You need a gwt.xml module in the Common package, anywhere below the
code you want to include.  These files don't need an EntryPoint in the
java source, they just need to be present.  You can even leave the
source + classes {you MUST have source, classes aren't enough} in
their jar, just create the same base package from Common in your
Client project, add a .gwt.xml module with nothing in it {maybe
inherit ...google.user} and inherit that in the Client module.

Your com.example.web and com.example.shared approximations aren't
actually in the same package, are they?

Think of the gwt.xml module definition files as GWT's way of saying
"import com.example.*;" when the .gwt.xml is in the com.example
package.  If you don't understand, just post the actual package names,
and I'll draw out a directory tree.  ...Making the IDE happy doesn't
matter to GWT, as it needs it's own import rules {since you can build
with ant as well, and it has no idea what your IDE settings are}.

G'luck!

Re: GWT capabilities for Dummies...

[Salvador Diaz]

Hi,

1. Yes, read the following section of the developer's guide:
http://code.google.com/webtoolkit/doc/1.6/DevGuideServerCommunication.html#DevGuideRemoteProcedureCalls
2. Here's the GWT widgets showcase: 
http://gwt.google.com/samples/Showcase/Showcase.html
3. See answer 1
4. Yes, there are several ways to do that, for a sample just google
gwt +spring
5. GWT RPCs are normal java servlets on normal java servlet containers
so you can do everything your servlet container allows you to.

Hope that helps,

Salvador

Re: Something is worong with my app in GWT 1.6

[bencoder]

Thank you, Jones.

I think that I can accept solution B that I mentioned above. The root
cause of this problem is just different file directory structure from
GWT 1.5.
If I follow solution B, the *.php files directory is actually outside
of application when it is deployed to a web server.

Re: How to handle colliding IMPORT statements

[Dean S. Jones]

This is normal Java, the only way to disambiguate is to use full
package qualification.
