the default URL for RequestFactoryServlet is /gwtRequest.

I have configured Spring, I have ContextLoaderListener and
DispatcherServlet,
they suppose to be the first to get initialized (bootstrapping
application context)

however, I notice GWT client connects "directly" to /gwtRequest

is there anyway to change this behaviour ?

I think about writing a Filter, but when the DispatcherServlet is not
invoked,
probably neither will the Servlet Filter.

I have conducted my experiments in test environment with JRE and
GWTTestCase,
in both cases the Server call is directly to the
RequestFactoryServlet,
and Spring's DispatcherServlet is completely ignored.

why is that, and how to change it ?

especially when adding Spring security filter.

if running in production mode, it might work,
because it would be within the container i guess, but I am not sure.

I would like to see some suggestions and feedback on this.

Thank You

can AutoBean detect changes ?

can AutoBean detect changes made to an object ?
(the same way EntityProxy/RF work?)

lets say a Widget presents a list of items to a user, to edit,
user starts editing only one or two field out of 10 fields.
can AutoBean detect the fields that have been changed,
so that only the changes are sent to the server for update ?

or is it only an encoder/decoder from JSON to Bean like objects and
vice versa ?

requestfactory, entityproxy has reference is always null

2010-12-21 Thread Mike

hi all:
suppose we have two entity proxy that has an reference relationship:
class AProxy
{
BProxy getBproxy();
}
class Bproxy
{
   String getName();
...
}

in UI, there is a list table used to display Aproxy,  one column is 
BproxyName, but it is always null. seem when i fetch all A Entity in server 
side, it can also fetch B entity, but at the client side, getBproxy() just 
return null.
how can i solve this problem?
thanks.

Re: Google Plugin In Spring Source Toolkit seems to be wipping out the project on run.

I had similar problem like Chris.

the problem was Eclipse/M2Eclipse conflict.

M2EClipse would overwrite Eclipse classpath, and
things would work and stop working at random.
especially after mvn clean.

It also affects JUnit,
if you google Eclipse Maven JUnit ClassNotFound,
you come across many issues that are still open

this is nothing new, many posts dating back to 2008 with the same
problem.
many hacks were proposed and I tried them all for two days,
with no luck, I then switched to IntelliJ and everything worked just
fine right away.

the reason I kept pushing for two days to make Eclipse work,
was to take advantage of CodePro Analytix, but unfortunately it is
only available for Eclipse,
and Clover by Atlassian is , well, pricey :")

Hi Rajeev, after working with Eclipse, Maven, and GPE 1.4 I've noticed
a few more things:

I'm now working with STS 2.5 (and ... some GWT) and Maven, and I'm
still running into the same problem.   My original problem seems to be
more of a Maven/Eclipse interaction issue.  Eclipse-clean !=
mvn:clean, and sometimes publishing an app to a Spring tc server in
Eclipse (and, btw, to the Jetty server in GPE) it fails to copy over
resources in target/ that mvn:package is supposed to copy over.

Lesson learned: be sure if you ever do a mvn:clean to do an Eclipse
project clean, and rebuild from Eclipse (and a GWT compile) before
doing a mvn:package .  This should keep the two environments in sync,
and the right things should copy over.

I'd rather not suffer a 12-permutation (&tc) GWT compile if I don't
have to, so I hope your recommendations bear fruit.

Thanks,
- C

How do I get the GWT compiler to produce a single JS file per permutation

HTML Link Cell

2010-12-21 Thread GregD

I would like to create a Column of Cells (for a CellTable) where each
cell displays an HTML link (the link will send information to an
application running on the user's machine (the app is IGV)) that it
gets from the row data.

Can SafeHtml be used for such a link?

Should I extend SafeHtmlCell, or do I need to extend AbstractCell?

Re: Plugin fails to connect to hosted mode server

Hi Alan,

Thanks for helping..

I tried telnetting and it was successful. I tried  and I got a
blank screen. I also tried 9997 and I got some weird characters
printed on the screen.
I tried deleting the directories under the war created by GWT,
restarted the server - same response
I tried deleting the classes under web-inf, restarted the server -
same response

I changed the debug level to All and got a warning saying no
favicon.ico. I put an icon file in there and then I got a 200. The
icon also appears on the tab image on Chrome. But the plugin fails to
connect never goes!

Thanks for the workaround.  It only works if you override the
setRowData() method with the following body:


setKeyboardSelectionPolicy(KeyboardSelectionPolicy.DISABLED);
super.setRowData(start, values);
Scheduler.get().scheduleDeferred(new ScheduledCommand()
{

  @Override
  public void execute()
  {

 
setKeyboardSelectionPolicy(KeyboardSelectionPolicy.BOUND_TO_SELECTION);
  }

Re: GWT 2.1.1 RequestFactory Strange Exception

Thank you, it all makes sense now.

However what you described is how GWT RF uses those details
to do its magic behind the scenes.

I am not clear what our responsibility is then ?
What should go inside the Locator ?

>From the code I posted,
http://paste.pocoo.org/show/308153/

I don't know what I should put in there.

I have a ServiceLocator ( one per application),
that locates Services. those Services are independent from GWT RF,
they can connect to persistent stores, do whatever they want.
and return a retult/perform action that is expected by RequestContext.

and what you described for Locators
@ProxyFor(value=PersonEntity, locator=EntityLocator)
public interface PersonProxy {


from your explanation I understood why Locator is important,
but what should we/the developers put in it ?
and do we need one per Entity or one per Application ?

sorry I repeated myself, I am still a bit confused :" )

Re: GWT 2.1.1 RequestFactory Strange Exception

The getId method is used generate a "stable id" that's transmitted to the 
client so that the object can be identified when it's later updated, and the 
find() method (see below) can be called with the appropriate identifier. You 
don't have to define a getId() in your EntityProxy, and if you do, it'll be 
resolved as a property, not by calling getId.
The getVersion method is used to send to the client the version of the 
object it "knows about", so that when it send it back to the the server 
(generally with changes), the server can quickly bail if it knows that the 
server-side version is different (i.e. getVersion is called to send the 
version to the client, and also at the very beginning of the server-side 
processing to check that the version known by the client is not out-dated, 
i.e. an optimistic lock). It's also used, just before returning to the 
client, to detect if a given object has been changed by the service methods 
(RF then generates the appropriate payload in the response so that an UPDATE 
event is dispatched on the client-side)

The find method is called to update the domain entity when you send one from 
the client to the server (RF will actually only send deltas of your changes, 
not the whole object, that's (one of) the point(s) of RF), e.g. to pass it 
to a persist() service method.

The create method is called when you send to the server an object that you 
RequestContext#create()-d on the client-side.

The isLive method is called for each object sent over the wire on a given 
request (from client to server and from server to client) to possibly 
generate the payload in the response so that a DELETE event is dispatched 
client-side.

Finally, getDomainType is useless, it's never called.

Re: Modular rpc blues

2010-12-21 Thread Andreas Horst

Another question just coming to my mind:

Where in the inherited module are you declaring the RPC servlet?

If you declare it in the inherited module's web.xml then make sure the Maven
GWT plugin parameter "webXml" properly points to it (Not sure how one would
do this - never did it myself - especially since  inherited modules usually
come as a .jar. If so does yours include the web.xml?).

If you declare it in the inherited module's module descriptor (a.k.a.
*.gwt.xml) all should be fine. Hence I assume you do not declare it
there? Look 
here
for
details about the module descriptor, note the  tag.

My 2cents: Use the second option.

Why? Because obviously your inherited module realizes functionality that is
to be reused. It is hence some sort of library and not (only?) an
application or even a .war packed web application. All our inherited modules
are _library_ modules, they don't get deployed on an _application_ server on
their own. Now if one of those features functionality through RPC (we have
some of those) we thankfully use the above mentioned  tag in the
module descriptor and let the Maven GWT plugin do its job. IMHO on the one
hand a web.xml does not belong into a common not "runnable" module and on
the other one a (.war packed) application is not best suitable for
inheriting functionality.

Re: GWT 2.1.1 RequestFactory Strange Exception

Thank you guys for the tips.
I got it to work!
Thank you very much !

I noticed a VERY STRANGE behaviour.

following your suggestion, I declared:

@ProxyFor(MyPersonEntity, EntityLocator)
PersonProxy

@Service(MyPersonService, MyServiceLocator)
PersonService


I noticed when methods in PersonService are declared "static",
ServiceLocator is "bypassed", and is NEVER used by RequestFactory to
look up "PersonService"
RF directly goes to PersonService.
This was strange, because what is the point of ServiceLocator then, if
it is going to be bypassed ?

to force RF to go through ServiceLocator, you have to remove "static"
from your Service methods.

This is where things get even more STRANGE:

if I do not define a Locator,
I get exceptions complaining PersonRequest did not pass validation.

however if I define a Locator (by extending Locator Interface)
I then have to implement bunch of methods: find/create/getId/
getVersion

I return NULL from all methods, and it still works !

why is that? and why we are forced to define a Locator, if we already
have a Service defined ?
my Locator does nothing !

you can see the code here:
http://paste.pocoo.org/show/308153/


from the debug statements, I see these methods being invoked:
[1022][INFO ][main][EntityLocator::22] - #EntityLocator
constructor called 
[1022][INFO ][main][EntityLocator:getId:45] - # get Id
#
[1023][INFO ][main][EntityLocator:getVersion:57] - ### get
Version ###

however, I returned null for all of them,
still the client receives the correct Id/Version as I set in my
PersonService#find method.

could someone from GWT Team please explain.

I am beginning to love the new RequestFactory, Thank You !

Actually the goal gwt:mergewebxml is really ALL you need (believe me, we use
it just like that for exactly what you are trying to). Please clarify what
you mean with "web.xml refers to external module". I assume either your
web.xml gets or already is troubled or your POM is not configured properly.

Re: UiBinder or GWT Designer

2010-12-21 Thread Thad

While I have not yet tried UIBinder on a problem in my environment, I
did try GWT Designer.  Very quickly I went back to coding my UI by
hand.

My interface is largely shaped by the results of calls to a database
via a clearly defined API.  That means I make a lot of GWT RPC calls
and act on the results, results that can vary widely.  GWT Designer
does not (or at least 2 years ago did not) support RPC calls.
Designer's recommendation was to write local routines to simulate the
call.  I found that approach unsatisfactory--it was both slow, and
prone to error. After all what better way to try out real world data
than by pointing at a real-world system?

By the time UIBinder was introduced I was too far along to go back and
retro fit it.  Now that my app is in release, I'm ready to take
another look at UIBinder, especially in relation to new GWT 2.1 stuff
like cell widgets.

Re: Facing some problems after switching to GWT 2.1 from GWT 2.0.4

Let me re-state it (once more): there was a bug in versions before 2.1.0, 
where you couldn't tell whether the user pressed the down arrow or the left 
parenthesis (or something like that).
GWT 2.1 fixes that bug, but then it exposes a more "low level" behavior 
where you directly get what the browser gives you; and Firefox has a really 
odd behavior (not to mention that it's different depending on the platform).
I believe it *cannot* be fixed while keeping the KeyDown/KeyPress dychotomy; 
only a higher-level API (such as what's in Google's Closure Library) could.

I mean you have to "javac" classes that are *referenced* from annotations 
(in this case, the PlaceTokenizer classes referenced from @WithTokenizers; 
that'd be true also of your service, domain object, locator or service 
locator with RequestFactory, unless you use @ServiceName and @ProxyForName).
Otherwise, GWT can work with only the *.java files, without the *.class.

AFAICT, only when generators read the annotations (i.e. when the

GIN is a bit special, it works directly from the compiled classes, never 
from the *.java files (which also means it won't see your "super-source" 
versions of classes)

Yes, UiBinder is only generating Java code from the XML, Java code that you

For the time being, each UiHandler method generates an appropriate 
EventHandler (anonymous) class that's attached to the appropriate widgets. 
In the future, it might do smarter things, but not yet.

Pro tip: use the "-gen" command-line argument to DevMode or Compiler so you 
can read the generated Java code.

Re: GWT 2.1.1 RequestFactory Strange Exception

in RequestFactory 2.1.1 documentations (source code),
there are many references to Domain and Domain Environment,

I am unclear what is meant by Domain Environment.
is it on the server side where RequestFactory work stops and our work
begins ?

it helps if the documentaton clarify the vocabulary,
Locator, Service, ServiceLocator, Domain, Domain Environment,
ServiceLayer

is ServiceLayer a DAO layer or a true Service Layer.

ServiceLayer vs Domain Environment ? what is the distinction between
the two ?

Re: Facing some problems after switching to GWT 2.1 from GWT 2.0.4

2010-12-21 Thread Casey

I too was using KeyPressEvent in 2.0.4 and it was working perfectly
but when I upgraded to 2.1.1 it stopped working. Based on Brian
Reilly's comment I changed the event to KeyDownHandler and the
comparison to event.getNativeKeyCode() == RETURN_KEY and it's back to
working again. So even though the workaround worked, I do believe that
this is a bug since it used to work in 2.0.4.

Re: Is there a way to get have GWT not compile a method into JS?

Then you have to go the 'subclass' route - create a common (shared) interface and have 
implementations for server and client
You can superclass the common parts into a 'shared' (probably abstract) class.  Solves the service 
side import issues.


I've done that several times and it works just fine. It may even simplify your 
unit tests.

Re: GWT 2.1.1 RequestFactory Strange Exception

I thought the idea behind 2.1.1 was to get rid of static ?

I am a bit confused on what is meant by the term "service" methods.

Normally we have a "Service Layer", and a "Data Access Layer"

Data Access Layer (all the DAOs), responsible for communicating with
persistent stores to find objects of a "given type"

findCustomerById, ByEmail, AllCustomers, AllCustomersWithCriteriaX
all of this goes into CustomerDAO

then you need a Service Layer, that uses many of these DAOs to satisfy
a use case.
PersonService, might use PersonDAO, AccountDAO, and more ..., performs
a business logic on them and take some action.

in RequestFactory 2.1.1, do you think the ServiceLayer and
ServiceLocator is just
for locating the DAOs or the Service objects as I described ?
(because in RequestFactory 2.1 even the DataAccess (DAOs) where inside
Entity class.

to achieve the complete isolation we need a ServiceLayer +
DataAccessLayer on top of our Entities.

with RF 2.1.1, can we specify just the Service method in GWT, and
leaving the job of dealing with DAOS to the Service object ?

I am planning to use it with Spring too.

in your case (spring), you need all 4 attributes ?

on PersonProxy we use @ProxyFor(EntityObject, EntityLocator)

on PersonService we use @Service(ServiceObject, ServiceObjectLocator)

so the EntityLocator is the DAO ? and ServiceLocator queries spring
context
to find the Service method to handle the EntityLocator ?

yet, all of these methods have to be static ?

Thank You

Re: GWT 2.1.1 , HelloMVP (Google provided example illustrating Activities & Places) : Compile error. Stacktrace enclosed.

are you suggesting we need to compile our custom annotations before
compiling other classes that use them ?

is this always the case ? or only if relying on generators ?


I encountered this problem when I defined my custom annotations,
which I used in conjunction with GIN BindingAnnotation.
and sometimes at initialization, I was getting exceptions,
suggesting the Annotations cannot be found, despite them being in
classpath.
(I noticed if I mvn clean, this happens, but on second run, it was
fine)

The annotations were not doing anything special,
just as markers for GIN Binding Annotations.


I thought it was Eclipse/Maven plugin problem, when I switched to
IntelliJ, everything worked just fine.
do you think the problem I had is related to scenario you described ?

Re: De-selecting a CellTable or CellView

2010-12-21 Thread John LaBanca

The logic changed slightly from 2.1.0 to 2.1.1 to try to make it respond
more naturally to use input, but there are a lot of special use cases.  Just
to make sure I understand correctly, this only happens when the
KeyboardSelectionPolicy is set to BOUND_TO_SELECTION and you remove the
selected item?  If you replace the data, but include the originally selected
item, it should remain selected.

It makes sense that if the selected item is lost, we should not reselect a
new item.  I created an issue to track this:

Re: RequestFactory entity proxies can't be cloned.

IIUC, you should use 2 distinct RequestContext, creating a new 
RequestContext each time you open the dialog box. That way, when the use 
clicks "cancel", you simply let the RequestContext be garbage collected, and 
any changes made to the object being scoped to a RequestContext would go 
away with it.
And of course, to make sure your object isn't already edited by your "main" 
editor (which would cause a "crossing streams" error if you try to edit it 
again in another RequestContext), if you display it here, make sure you 
annotate the editor with @Ignore and use a specific EditorDriver for the 
sub-editor where you'd do a display() instead of edit().

De-selecting a CellTable or CellView

2010-12-21 Thread Frank Mena

Looks like some of the behavior of CellTable and CellList has changed
between v2.1.0 and 2.1.1.

When you initially add data now, no item is selected.  After any item
is selected, there is no way to replace all the data in the table or
list without it also selecting the first item.  There is no method I
could find to do this.

If I replace the contents of the table, I do not want any item
selected automatically or I need a method that lets me turn this off.
Currently, the only way I can prevent this is to set
KeyboardSelectionPolicy to DISABLED.

Is there a way to disable auto-selection or to turn off a selection?

I agree- if (!GWT.isClient()) {} is definitely going to be optimized out of
the js.

Even if you could mask out an entire method, how would you handle the server
side only includes needed to make it interesting?

Re: Is there a way to get have GWT not compile a method into JS?

2010-12-21 Thread John LaBanca

The GWT compiler performs dead code elimination, so if you never call the
code from the client, it will not be compiled into javascript.  You can
create your own annotation if you want to annotate the method so other
people on your team know not to use it.

If you want the API to be technically correct, you could create a common
base class in your shared package and subclass it in your client and/or
server packages.
com.myapp.shared.CommonUtils
com.myapp.client.CommonClientUtils extends CommonUtils
com.myapp.server.CommonServerUtils extends CommonUtils

Re: Is there a way to get have GWT not compile a method into JS?


Sorry for jumping in, but you could use:

public void yourMethod(...) {
   if (!GWT.isClient()) {
everything in your method.
}

}

The complier should then ignore everything inside the conditional.

However, it seems a bit of a kludge to exclude the whole method. Another option is sub-classing and 
have a server-side version which is a sub-class of your shared class - I've done that before and 
IMHO its a bit more elegant.

Re: Is there a way to get have GWT not compile a method into JS?

I was hoping to do it within a class.

For instance, say have method a() only available on the server.

In the  tag of the module XML file you can specify the

Re: GWT for mobile

2010-12-21 Thread Falcon

bruce, I currently am doing just that.

I'm having to make several of my own widgets as opposed to using some
of the built-in GWT widgets (and you may have to make your own
implementations of built-in widgets for certain platforms), and your
mobile targets will need decent JavaScript support (i.e. Blackberry <
4.6 isn't going to work) but it's definitely possible.

Re: Plugin fails to connect to hosted mode server

Following my previous comment - you can easily check by using a windows command prompt and telnet 
, e.g.


telnet 127.0.0.1 

if the firewall is blocking it, you'll get a 'can't connect to server' error, otherwise the screen 
will go blank and you'll get a weird prompt (the gwt rpc connection doesn't print any kind of 
message.) Not very elegant, but its a quick and dirty check.

Hi,

When I try to run the GWTs sample application project in the hosted
mode on chrome, the static parts of the page load and then it throws
an error saying plug in fails to connect to the hosted mode web
server.

My system config is below:
OS: Windows 7 Home Premium (Windows firewall off, Kaspersky firewall
on)
JDK: java 6 update 23 (64 bit JVM)
Eclipse Helios: 64 bit
GWT SDK : 2.1

I have installed the 32 bit jdk and in the run configurations I am
ensuring that the JVM that its running on is 32 bit.

The same thing works on my other PC running windows XP on a 32 bit
JVM.

I am not sure what I am doing wrong. Could someone please help...

Thanks
Sethu

Re: Trying to split deserialization process after RPC call

2010-12-21 Thread Damien Picard

Thank you for your advices.

I think I will linearize the tree as a List by replacing the strong
reference link between an Option and its childs to a String meaning the id
(the id is an attribute) of the child options.

Then, I will serialize the option list to a json String with flexjson and
send it to the client over GWT-RPC.

On the client, I think that the json String deserialization will be done
quickly ; I've seen on StreamReader source code that the String
deserialisation does not lead to a lot of compute time because the HTTP
response is String itself. Then, I will deserialize this json String with
the eval() method, and I will try to map it to my Option type with a
JavaScript Overlay Types.

And, if there is a need to split deserialization into multiple deferred
command, I will split my json String into multiple json string before
evaluating this with eval(), and do the eval() on each sub-sequence json
string in a deferred command. Even if this split is not simple...

What do you think about this solution ?

Re: DockLayoutPanel and StackLayoutPanel problems in IE7

2010-12-21 Thread Alejandro D. Garin

Hi, I'm using the new layout panels and works very well for me. Can you make
a visual mock-up of your layout for the 5 levels?

thanks.

Re: Plugin fails to connect to hosted mode server


Hmm...

Have you checked that port  (if that's what you are using) is blocked in 
the Windows firewall?

The times I've seen this there has been a networking problem such that the client can't reach the 
server. That would explain why it works on one m/c and not the other. I think the 32 bit vs 64 bit 
is a red herring - I use Win 7 X64 with a 64 bit JVM all the time and have no problems.

To: "Google Web Toolkit"

Hi,

When I try to run the GWTs sample application project in the hosted
mode on chrome, the static parts of the page load and then it throws
an error saying plug in fails to connect to the hosted mode web
server.

My system config is below:
OS: Windows 7 Home Premium (Windows firewall off, Kaspersky firewall
on)
JDK: java 6 update 23 (64 bit JVM)
Eclipse Helios: 64 bit
GWT SDK : 2.1

I have installed the 32 bit jdk and in the run configurations I am
ensuring that the JVM that its running on is 32 bit.

The same thing works on my other PC running windows XP on a 32 bit
JVM.

I am not sure what I am doing wrong. Could someone please help...

Thanks
Sethu

If you really want it, yes: override all the resolveXxx on a 
ServiceLayerDecorator to totally by-pass the stock ResolverServiceLayer 
(which calls the RequestFactoryInterfaceValidator).
See also: http://code.google.com/p/google-web-toolkit/issues/detail?id=5761

Re: DockLayoutPanel and StackLayoutPanel problems in IE7

2010-12-21 Thread mike b

So, I spent yesterday getting it to work in IE7 with unpredictable
results. Basically, I used DockPanel in my Layer 4 (from above).

This morning, re-re-reading the cryptic documentation on the website,
I found that I had not inherited from ResizeComposite. This was
actually plainly put, but I missed it somehow.  Note noted above is
that all of my "Layers" are my classes with the various LayoutPanels
in the initWidget().

Now I'm having predictable success with implementing in FF.  However,
I'm back to the same issue in IE7 nothing below Layer 4 will
display.

I'm also having to basically remove any VeritcalPanel or
HorizontalPanels from the app if they use any widget w/ implemented in
a div tag (like the ToggleButton) as the results are completely un-
predictable.

Does anyone know if upgrading to GWT 2.1.1 would help w/ this?

Thanks!!

Re: CellTable: Style cells differently wihtin a column

2010-12-21 Thread Subhrajyoti Moitra

Here some code snippet might help..


Cell qCell=new MyQuoteCell("click");//custom abstract cell defined
below.
Column qCol=new Column(qCell) {
@Override
public MyQuote getValue(MyQuote object) {

return object;
}
};


public class MyQuoteCell extends AbstractCell {

public interface MyQuoteTemplate extends SafeHtmlTemplates{
@Template("{0}")
SafeHtml aDiv(String qn);
@Template("{0}")
SafeHtml bDiv(String qn);
}

private static MyQuoteTemplate template=null;

public MyQuoteCell(String... consumedEvents) {
super(consumedEvents);
if(template==null){
template=GWT.create(MyQuoteTemplate.class);
}

}

@Override

if(value!=null){
if("A".equals(value.getQuoteType())){
sb.append(template.aDiv(value.getQuoteName()));
}else if("B".equals(value.getQuoteType())){

2.1.1 fails in SimpleRequestProcessor.processInvocationMessages when nothing to invoke

2010-12-21 Thread Cory Prowse

Hi,

I believe I've uncovered an error in version 2.1.1 of SimpleRequestProcessor 
when there are no invocations and only operations in a RequestMessage from the 
client (stacktrack at end of email).
I'm checking here before creating an issue.

I am using an editor on the client to modify a property, then flushing and 
firing.

So the RequestMessage from the client is:
---
{Operations=[{PropertyMap={title=150349-0 Title CHANGED}, 
ServerId=IjY1Zjg4ZjVlLWFlNDItNDcxYi04NGNkLWE2MWJmOGUxNzBjZCI=, 
Operation=UPDATE, Version=MQ==, 
TypeToken=au.projectx.gwt.request.ArticleProxy}]}
---

With the following stacktrace:
---
[#|2010-12-21T15:05:48.626+1100|SEVERE|glassfish3.0.1|com.google.gwt.requestfactory.server.RequestFactoryServlet|_ThreadID=28;_ThreadName=Thread-1;|Unexpected

java.lang.NullPointerException

com.google.gwt.requestfactory.server.SimpleRequestProcessor.processInvocationMessages(SimpleRequestProcessor.java:414)

com.google.gwt.requestfactory.server.SimpleRequestProcessor.process(SimpleRequestProcessor.java:218)

at 
com.google.gwt.requestfactory.server.RequestFactoryServlet.doPost(RequestFactoryServlet.java:118)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:754)
---

It seems to me that either SimpleRequestProcessor.processInvocationMessages() 
needs to cater for a null List or 
RequestMessage.getInvocations() should return an empty list instead of a null.

how to debug service calls, which do not come through

Hi,

i am using the newest version of GWT. I have a service with a bunch of
methods. Some work, some don't. The one,
that does not work, seems simply not being called on the server side.
If i put a breakpoint in the method of the service implementation
on the server side, it doesn't get called. But the AsyncCallback is
created on the client side.

Unfortunately there is no exception or anything being thrown. Do you
have any tips, how i could debug this?

CellTable: Style cells differently wihtin a column

2010-12-21 Thread Thomas

Hi,

I have been searching through this forum and other places on the
internet to find examples of how to style cells differently within a
column - but without luck. I hope you can help me.

Here is my problem:

I have a CellTable showing a list of objects. A simplified example of
this object looks like this:

class MyQuote {
public String getQuoteName();
public String getQuoteType();
}

My problem is that I want to apply style A to the cell if quoteType is
X and apply style B to the cell if quoteType is Y. How can I do that?

I have tried by creating a custom column class (extends Column) and a
custom cell class (extends ClickableTextCell) but without luck. The
column class is aware of the MyQuote object and thereby both quoteName
and quoteType but if I apply the styling in the column class getValue
method - for example "quoteName" - the HTML gets
escaped. I have also tried to apply styling in the cells render method
but here I have only knowledge to the value being displayed, which is
quoteName, and not quoteType so I cannot determine the style class.

Regards,
Thomas.

Plugin fails to connect to hosted mode server

2010-12-21 Thread Sethu

Hi,

When I try to run the GWTs sample application project in the hosted
mode on chrome, the static parts of the page load and then it throws
an error saying plug in fails to connect to the hosted mode web
server.

My system config is below:
OS: Windows 7 Home Premium (Windows firewall off, Kaspersky firewall
on)
JDK: java 6 update 23 (64 bit JVM)
Eclipse Helios: 64 bit
GWT SDK : 2.1

I have installed the 32 bit jdk and in the run configurations I am
ensuring that the JVM that its running on is 32 bit.

The same thing works on my other PC running windows XP on a 32 bit
JVM.

I am not sure what I am doing wrong. Could someone please help...

Thanks

RPC Serialization Format

2010-12-21 Thread travemm

Hi,

I'm looking for details (references to code are fine) about how the
rpc messages are formatted. I'm doing penetration testing for a
client's GWT rpc servlets but cannot access their source or discuss
with their developers (black/grey box testing).

Looking at an rpc request it appears to be formated the following way:
#|#|#|URL|StrongHash|Class_Name|Method_Name|ARG1_Class_name|
ARG1_member1|...|ARG1_memberN|ARG2_Class_Name|ARG2_member1|...|
ARG2_memberN|#|#|#|#.|#|#|#

The first three #'s appear to be related to the request and number of
args, not %100 sure on this relation.
The last set of #"s I'm very confused on what they do and mean.

I have the following use case that will probably result in a
successful penetration test for my client.

A request to method M1 sends and object with all the fields set to
NULL.
A request to method M2 sends the same object and some additional
objects, but with all the fields set to valid values.
I need to create a request to M1 with the same object sent to M2.
Since M2 also has additional arguments the RPC requests are rather
different and it isn't straight forward for me.

Of course through a hundred hours of reading GWT source I could figure
this out, but hopefully there is something simpler. I can request a
copy of the class file for the class I need to serialize and send to
M1, if that will allow me to make the request to M1 using GWT
interfaces.

UiBinder and event bubbling

2010-12-21 Thread alab

Prior to UIBinder in gwt, I wrapped elements in a HTMPanel which
basically handled all the events for its child elements. So instead of
attaching an eventlistener to multiple widgets, I just attached it to
the parent container and used event bubbling. Can I do this in
UIBinder? I know in the backing class for the yourclass.ui.xml, you
can use UiHandler to handle event delegation but is this optimal? Am I
still adding multiple listeners or is GWT doing something behind the
scenes and attaching only 1 event handler.

Re: GWT 2.1 CELL TABLE

2010-12-21 Thread Owen Powell

Thanks hagar. 

I followed your instructions with two changes:

1. Added "import import 
com.google.gwt.user.cellview.client.CellTable.Resources;" the interface in 
Step 1.
2. I was getting an error regarding unobfuscated class names in my CSS file, 
so I appended "cellTable" to all the CSS classes (as per the recommendation 
of the compiler). 

Now I get the following error:

[ERROR] [amdb] - Deferred binding failed for 
'amdb.client.ui.table.CellTableResource'; expect subsequent failures
[DEBUG] [amdb] - Rebinding 
com.google.gwt.dom.client.StyleInjector.StyleInjectorImpl

If anyone has an idea, please let me know.

RequestFactory entity proxies can't be cloned.

I posted this in gwt-contributors but I feel this might be the more 
appropriate group.

I'm attempting to switch to using RequestFactory instead of GWT-RPC 
and manually creating DTOs. It's been going pretty well, except I've hit 
one use-case that is just a brick wall.
 
I have a panel that is an Editor which uses 
a RequestFactoryEditorDriver to handle the editing. One of the properties 
of DocumentProxy is another proxy, which I want to edit in a dialog box 
that shows when a button is clicked in the panel. The dialog is another 
Editor.
 
The problem is that anytime something changes in this dialog, I want 
to flush the editor, send the current values to the server for validation, 
and report any errors right away. This works fine, but the dialog box has 
a cancel button, which should revert any changes made in the dialog box.
 
I was able to do this before by storing the original value when it's 
set, and editing a clone while in the dialog box. But entity proxies can't 
be usefully cloned in any way that I currently see, so I'm at a loss as to 
how to get this behavior.
 
Any suggestions? I'm currently on GWT 2.1.1rc1, should be upgrading to 
2.1.1 soon.

different banks, the getSession() returns the wrong HTTP Session and
the user is able to see data from the wrong bank.

We are using GWT 2.0.4.

Working example, based on bradr note:

1. Create new interface:
--
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.cellview.client.CellTable;

public interface CellTableResource extends Resources {

public CellTable.Resources INSTANCE =
GWT.create(CellTableResource.class);

/**
 * The styles used in this widget.
 */
@Source("style/CellTable.css")
CellTable.Style cellTableStyle();
}

2. Copy CellTable.css 

from: http://code.google.com/p/google-web-
toolkit/source/browse/branches/2.1/bikeshed/src/com/google/gwt/bikeshed/list/cli
ent/CellTable.css?r=8062
into the same directory (or subdirectory of CellTableResource).

3. Create your CellTable with the resource file:

CellTable table = new CellTable(20, 
CellTableResource.INSTANCE);

Re: GWT 2.1.1 RequestFactory Strange Exception

@ProxyFor(value = Person.class, locator = PersonLocator.class)

then having a PersonLocator which implements Locator would fix this 
for you.

But in order to get your static service methods (besides just the find 
method), you need a ServiceLocator for your service:

@Service(value = PersonService.class, locator = MyServiceLocator.class)

I'm not sure if the locator for the service is necessary if it has a default 
constructor. We use Spring, so we have a service locator that just pulls the 
bean out of spring.

HTTP Session Problem

2010-12-21 Thread skippy

I am using this in a serviceImpl class:

HttpSession session = getThreadLocalRequest().getSession();

Sometimes when a user has two tabs in IE opened to different logons to
different banks, the getSession() returns the wrong HTTP Session and
the user is able to see data from the wrong bank.

We are using GWT 2.0.4.

Totally agree with you comments, Jeff. I evaluated GWTDesigner because, generally speaking, I like
RAD tools. However, I found it very slow to start - maybe a bug or something - but, being
comparatively happy with XML, HTML and CSS I found that my workflow was smoother using UiBinder and
it was much quicker to make changes and see what was happening. Also, I tend to use a lot of my own
widgets and programmatically add and removed them from pages, and so the direct UiBinder approach
made that easier.

I stress that these are my own personal opinions and YMMV. I'm interested in
other people's opinions.

Alan

My advice would be to try both. The latter will give you more flexibility.

Re: gwt + spring security

2010-12-21 Thread Travis Camechis

instead of using that I created my own custom Spring Security
SuccessHandlers and Failure Handlers that returns JSON back to the client.
 I then let the client handle the place management based on
success:true/false.  At this point I can also send credentials back in the
JSON as well.
