Re: How to share an RPC RemoteServiceServlet between apps?

[Alfredo Quiroga-Villamil]

Rob:

If I am not mistaken you can override in your ServiceImplementation a
couple of methods (your choice which one). In RemoteServiceServlet, you
will find:

getSerializationPolicy
doGetSerializationPolicy
Likely the latter will be easier to override. There, "moduleBaseURL" should
help you do what you want. You'll have to set it to the same baseURL
regardless of what the client sends.

Hope that helps.

Regards,

Alfredo

Re: CellTable styles incorrectly on IE9

[JoseM]

So then it seems that this is related to that other bug where GWT thinks the 
browser is Chrome since Chrome Frame is installed (but maybe not being used) 
and it uses the webkit specific browser code and not the Trident/IE one. (I 
believe the bug is more of a Chromium bug than a GWT bug).

Is there any way to remove the sort arrow decorator in a header of a CellTable?

[JoseM]

You can control what to show for that with the CellTable Resources. You would 
have to pass in your own resources to the CellTable constructor that overrides 
the sort style to display what you want.

How to share an RPC RemoteServiceServlet between apps?

[Rob]

Hi,
I want to have a service used by several modules. I put the implementation 
servlet in a root web app, and connected to it, from the client side, by 
specifying the endpoint like this...

  ServiceDefTarget t = (ServiceDefTarget)service;
  t.setServiceEntryPoint("/commonService");

So "/commonService" is url path that maps to the servlet.  But when it 
connects I get errors on the server side:

  ERROR: The serialization policy file 
'/forums/discussions/7B344C69AD493C1EC707EC98FE148AA0.gwt.rpc' was not 
found; 
  did you forget to include it in this deployment?

So it appears that on the server side, in the shared web app, it's looking 
for an rpc file with a path "forums/discussions" which is specific to the 
client module.  I can get things to work by copying these files to the 
shared web app, but that means I'll have to create copies of the .rpc files 
at different paths for every client that uses the shared service.  

Is there way way to avoid this by telling the servlet where to find the rpc 
files, or ... ?

thanks,
Rob

Inheriting module resources (images, css etc)

[manstis]

Hi,

What is the best practice for inheriting resources?

We've been separating resources from code, much like this:-

Module A

org.test.modulea.client.widgets
->class MyWidget extends Composite {

  private MyResources resources = GWT.create( MyResources.class );

  public static interface MyResources extends ClientBundle {

@Source("../resources/images/anImage.png")
ImageResource anImage();

  }

} etc

org.test.modulea.client.resources.images
-> anImage.png

Module B



However we are finding we need to duplicate the client.resources
package in ModuleB as well.

>From what I have read and understand I believe this is caused by the
relative "source" URI being prefixed with ModuleB's name and hence
they are being looked for in org.test.moduleb.client.resources.images.
Looking at Google's examples images appear to always be in the same
package as the code needing them with no use of "@Source". This I
suspect removes the URI issue.

I'd love to hear what is thought as best practice and how to avoid the
re-use problem we have.

Thanks for reading,

Mike

Re: GWT & Spring

[Filippo De Luca]

Usually I implement the Service interface in a Spring bean, and I write the 
RemoteServlet implementation delegating all method to the Spring bean. 
Because the servlet is outside Spring transactional demarcation. You an 
also use threadlocal to pass request and response to the Spring bean (as 
GWT do).

How to format properties file for Messages and @Select

[Filippo De Luca]

Hi,
I have wrote an interface containing this method:

String errorRemovingWidget(@Select Type type);

Type is an enum.

The properties file contains:
errorRemovingWidget=Could not remove widget from dashboard
errorRemovingWidget[A]=Could not remove an A from dashboard
errorRemovingWidget[B]=Could not remove an B from dashboard

But it doesn't work. How the properties file messages should be formatted 
to work with the Select?

DatePicker next/prev month events

[Nikola Markovic]

Next and previous month buttons in MonthSelector are declared as private 
and have a default behavior of adding/subtracting one month and refreshing 
the datepicker. There are no events that fire when this occurs. I've tried 
to fire my own event, by extending the MonthSelector class and implementing 
a similar solution like in DefaultMonthSelector, plus firing the event. The 
problem is that, while calling addMonth(+1) (or -1) from 
DatePickerComponent i get an illegalAccessModifier exception saying I'm 
trying to access the com.googl... package from my package. 

Tried to work around by calling some other methods, didn't work. 

Tried DateChooser(smartGwt) component, but it's all native code and all I 
can get from the component itself is the name of the Icon rendered as 
next/prev button. Not sure if messing with native code could solve my 
problem here.

Thanks in advance,

Nikola Markovic

you could just include the generated js code into your portlet and

RPC Serialization of an Interface..

[Viktor]

Hi all,

for my application i need to parse custom objects with the simple-xml
framework from the server side. This works fine. But if a make a rpc
call from the client side to geht the Objects i get this Exception:

 [WARN] Exception while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type 'Media'
was not included in the set of types which can be serialized by this
SerializationPolicy or its Class object could not be loaded. For
security purposes, this type will not be serialized.: instance =
Media@12342d9
at
com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serialize(ServerSerializationStreamWriter.java:

44)
at
com.google.gwt.user.client.rpc.core.java.util.ArrayList_CustomFieldSerializer.serialize(ArrayList_CustomFieldSerializer.java:

The Media Class look like this:

public class Media implements Serializable {

/**
 *
 */
private static final long serialVersionUID = -4959495795968436441L;

public Media() {
}

@Attribute(required=false, name="condition")
private String conditionText = null;

@Attribute(required=false, name="conditiontype")
private Executable.Type conditionType = null;

@Attribute(required=true)
private String src = null;

@Attribute(required=true)
private String type = null;

@Attribute(required=false)
private String name = null;

@Element(required=false)
private Condition condition = null;

public String getSource()
{
return src;
}

public void setSource(String source)
{
this.src = source;
}

public String getType()
{
return type;
}

public void setType(String type)
{
this.type = type;
}

public void setConditionText(String conditionText) {
this.conditionText = conditionText;
}

public String getConditionText() {
return conditionText;
}

public void setConditionTypeText(Executable.Type conditionType) {
this.conditionType = conditionType;
}

public Executable.Type getConditionType() {
return conditionType;
}

public void setCondition(Condition condition) {
this.condition = condition;
}

public Condition getCondition() {
return condition;
}

public void setName(String name) {
this.name = name;
}

public String getName() {
return name;
}

@Commit
public void createCondition() {
if (getConditionType()!=null && getConditionText()!=null)

setCondition(ConditionFactory.createCondition(getConditionType(),
getConditionText()));
}

Executable and Condition are Interfaces.. i guess that is the problem,
because a interface couldn't implement Serializable. Is there a way to
put these interfaces trough rpc? or is there a workaround?

thanks and greetings
Viktor
