Re: [aspectj-users] Method not visible using this in pointcut

["Luiz Antonio Soares Filho" <luiz@xxxxxxxxxxxxxx>]

Hello Ramnivas,

I read your book AspectJ in Action and it helped me a lot to make my graduate thesis that I will finish in the end of this year.

Well, I'm using LTW and when I use a privileged aspect the error turns into a warning:
"this affected type is not exposed to the weaver: com.bea.wlw.netui.pageflow.FlowController (needed for privileged access) [Xlint:typeNotExposedToWeaver]"

So I think that I cannot go this way.

Then I tried to use reflection to make it works, but I had problems when I was testing and these problems aren't related to the use of reflection.

The problems that appear in the server application console are:

[GenericClassLoader@1e9d337] error can't determine modifiers of missing type com
.bea.wlw.netui.pageflow.FormData
when processing type mungers ejb.manager.DocumentoSessionRemote
when processing type mungers
when weaving
 [Xlint:cantFindType]
[GenericClassLoader@1e9d337] error can't determine modifiers of missing type com
.bea.wlw.netui.pageflow.PageFlowController
when processing type mungers ejb.manager.DocumentoSessionRemote
when processing type mungers
when weaving
 [Xlint:cantFindType]

These problems are printed repeatedly and only the classes that appear in "when processing type mungers ejb.manager.DocumentoSessionRemote" changes.

Any idea?

Thanks,
Luiz Antonio

You may mark the aspect as 'privileged'. 

public privileged aspect ... {

   ...

}

Alternatively, you may use reflection along with the AccessibleObject.setAccessible() method.

Hello,

I have a join point that need to expose the type of the instance.
I used this(type) pointcut. When I call the method getRequest() from the type this error occurs:
"The method getRequest() from the type FlowController is not visible"

I think this error is happening possibly because getRequest is a private method from FlowController. How can I solve this?

Here is my code:

private pointcut tratarExcecao(Exception ex, String actionName, PageFlowController page) :
        execution(* *Controller.exception(..)) &&
            args(ex, actionName, *, *) && this(page);

    before(Exception ex, String actionName, PageFlowController page) : tratarExcecao(ex, actionName, page) {
        String displayMessage;
        if (AppException.isMensagemNegocio(ex)) {
            String keyError = AppException.obtemKeyErro(ex);
            displayMessage = "Erro: " + actionName;
            page.getRequest().setAttribute("errorMessage",displayMessage); //ERROR HERE
        }
    }
