Using Canvas.drawText not working

Anonymous — Wed, 29 Sep 2010 16:53:42 -0000

Hi
I am trying to draw text on a Canvas. I extracted a bitmap font as follows:
java -classpath ./gwt-widgets-0.2.0.jar org.gwtwidgets.fontcreator.BitmapFontCreator sans12 Sans-12-Plain /home/chris 12-128,225-320,330-407
This created 2 files, sans12.png and sans12.txt which i placed in a fonts subdirectory of my war.

In the webapp I then call:
...
font = Canvas.createBitmapFont("fonts/arial12.png", "fonts/arial12.txt", new FontLoadListener() ...
followed by canvas.setFont() API and finally do
canvas.drawText("Some text", 5, 5);

On execution, the createBitmapFont api blows up with a ArrayOutOfBoundsExeption as follows:

java.lang.ArrayIndexOutOfBoundsException: 1
at org.gwtwidgets.client.ui.canvas.impl.BitmapFontImpl.parseHeader(BitmapFontImpl.java:64)
at org.gwtwidgets.client.ui.canvas.impl.BitmapFontImpl.onResponseReceived(BitmapFontImpl.java:194)

at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
at java.lang.reflect.Method.invoke(Method.java:597)

Can someone help to let me know why. I am using GWT2.0.4 and gwt-widgets-0.2.0.

Can't download from Maven repository

Adding gwt-widgets to my ivy build file results in the following error:

public: bad organisation found in http://repo1.maven.org/maven2/net/sf/gwt-widget/gwt-widgets/0.2.0/gwt-widgets-0.2.0.pom: expected='net.sf.gwt-widget' found='org.gwtwidgets'

Update GWTRPCServiceExporter.processCall to support GWT 1.6

Tom Wilczak — Fri, 16 Oct 2009 16:43:52 -0000

The method body of processCall in the 1.0 release of GWTRPCServiceExporter does not invoke RemoteServiceServlet.onAfterRequestDeserialized(RPCRequest).

I believe this is not intentional and may be the issue that was referenced in a previous bug report with a similar title.

Current method reads as follows:

@Override
public String processCall(String payload) throws SerializationException {
try {
// Copy & pasted & edited from the GWT 1.4.3 RPC documentation
RPCRequest rpcRequest = RPC.decodeRequest(payload, null, this);

Method targetMethod = getMethodToInvoke(rpcRequest.getMethod());
Object[] targetParameters = rpcRequest.getParameters();

...

}

This request is to change the body of processCall to invoke the onAfterRequestDeserialized method as follows:

Method targetMethod = getMethodToInvoke(rpcRequest.getMethod());
Object[] targetParameters = rpcRequest.getParameters();

...

}

MethodInterception AOP does not work

Anonymous — Wed, 21 Nov 2007 14:51:07 -0000

Hello. I have problem with using spring AOP with beans which extend GWTSpringController. Here is my config:

<bean id="urlMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop <prop key="/admin/UserService.gwt">userService</prop>
</props>
</property>
</bean>

UserServiceImpl extends GWTSpringController. The code works fine and there is not problem with execution. The problem starts when i want to use AOP advices. I need this for security (acegi supports URL security and methodInvocation security). I want to use method security.

</bean>
<aop:config>

<aop:aspect ref="securityAspect">

<aop:pointcut id="theExecutionOfSomeFooServiceMethod"
expression="execution(* some.client.rpc.UserService.*(..))"/>

<aop:around pointcut-ref="theExecutionOfSomeFooServiceMethod"
method="profile"/>

</aop:aspect>
</aop:config>

it does not work. When i use the same aspect in another pointcut ex. execution(* some.client.rpc.AdminService.*(..)) it executes well. My implementation of UserServiceImpl invokes AdminService.

So basically i cannot use aop with beans which extend GWTSpringController. I suspect Reflection is causing problems. Probably AOP does not work with reflection.

I also tried to use org.acegisecurity.intercept.method.aopalliance.MethodSecurityInterceptor which again works for AdminService and not for UserService.

Is it possible to run such thing using GWT-SL ??

Do the GWTHandler generated proxies support Spring tx?

Anonymous — Thu, 11 Jan 2007 22:20:09 -0000

Hello,
we use the GWTHandler together with Dozer to implement a proxy layer between the Spring driven core application (business logic and persistence) and the GWT application.

The core application contains all DAOs. The GWT-visible RPC-services are plugged into the Spring context using GWTHandler.

Unfortunately we are facing a transaction isolation problem when Dozer tries to convert core model beans to GWT model beans. The result is that the lazy-loaded Hibernate bean collections can't be initialized due to a closed session/transaction.

We have:
GWTLoginService.login()
->@Transactional:UserDAO.findUserByLogin()
->Dozer.convert()

We want the transaction demarcation one level above, in the GWTHandler enhanced RPC-service:
@Transactional:GWTLoginService.login()
->@Transactional:UserDAO.findUserByLogin()
->Dozer.convert()

Is this possible with GWTHandler ?
