Any listener for class method being invocated?

hi there all,
is there any class listener that can monitor any instantiation of class and invocation of methods?
thanks

AOP is indeed dangerous, when people abuse it. They miss out all the blurb about what an aspect is, and what cross-cutting concerns are, and just get seduced by the fact that you can nail on, at runtime, extra bits of control flow you hadn't previously considered. Ouch!

Custom User Decision for Class Method in Task

Hi Expert,
I have a screen for user decision(Approve/Reject with some comments field). When i execute the process it works fine for all cases, but when i don't click any decision and come back from the screen, then also this task gets completed and workflow starts executing next step. Here in this case, i want workitem to remain in inbox same as what happen in case of user decision step.
Do i need to put this task in loop till i get a decision or some other way i can solve it? I have tried putting this method as Synchronous and non-Synchronous method. I am not sure if this issue is, because i am using Class method. Please help.
Regards,
Pritam

Hi Mike,
I have got a solution for this. If we make the task as Asynchronous task with a terminating event. Till the time event is not triggered process workitem will remain in inbox. This event can we triggered at any user decision only.
Is there any flow in this logic? I have tried it for few cases and it worked, but not sure if there will be any case where it will not work? any suggestion?

WMI V2 equivalent of WMI V1 for Classes, Method or attribute

Hi Guys,
Since in Hyper V 2012 R2 the support for WMI 1 is removed, Hence we are migrating our applications from WMI V1 to WMI V2, Is there is any table or something which can give me WMI V2 (Classes, Method and attrib) equivalent of WMI V1 (Classes, Method and attrib).
Thanks

For most of them you simply add the v2 to the namespace, that is it.
There is MSDN documentation:
http://msdn.microsoft.com/en-us/library/hh850319(v=vs.85).aspx
and a series of blog posts by Taylor Brown as well:
http://blogs.msdn.com/b/taylorb/
(unfortunately, he didn't tag them as v2 examples so you have to dig through the list)

Is there any use for Class.getTypeParameters()?

This is a quote from another Thread in this forum:
How does erasure destroy reflection-related information? Methods getGenericInterfaces, getGenericSuperclass and getTypeParameters on java.lang.Class allow you to retrieve a lot of information on generic issues regarding a class. Obviously, that information is thus not destroyed.
While I do agree that Generics do not destroy reflection, I wonder what they add to it.
New types and methods are Class.getTypeParameters(), the interfaces java.lang.GenericDeclaration, java.lang.reflect.TypeParameter, java.lang.reflect.ParameterizedType etc...
Could someone please give me an example of what I could do with all these new types and methods?
It has been decided that Generics are implemented as a compile-time feature. At runtime, no information about the instantiated type parameters exists anymore. OK, so why clutter the core Java packages with a lot of seemingly useless new types and methods?

so why clutter the core Java packages with a lot of
seemingly useless new types and methods?This is a very good question, and something I've been wondering about myself. I cannot determine how to get the runtime to give me an instance of WildcardType or ParamaterizedType, for example.
Here's an extremely contrived example of how you can use Type bounds to effect runtime behaviour:
    class Processor<T> {
    class StringProcessor<S extends String> extends Processor<S> {
    public void whatKindOfProcessorIsItAnyway(Processor p) {
        Type processorType = p.getClass().getTypeParameters()[0].getBounds()[0];
        if ( String.class.equals(processorType) ) {
            System.out.println("I'm a string processor");
        } else {
            System.out.println("I process these: " + processorType);
whatKindOfProcessorIsItAnyway(new StringProcessor<String>());
        whatKindOfProcessorIsItAnyway(new Processor<Integer>());Outputs:
I'm a string processor
I process these: class java.lang.Object
So you can see I can switch based on the type bounds compiled into the program, but I have no way of knowing that the second processor is actually instantiated with Integer, due to erasure.
Infact, the only reason I would know anything about the actual type argument in the first instance is because String is final so '? extends String' -> String, for what its worth.
Whether I can write a program that's actually useful using this information I've yet to determine, but I can imagine it could be useful for code generation.

Apple does not repair just parts of the iPhone 4s, if you are wiling to pay the service fee, Apple will replace your device with a refurbished one:
Out-of-warranty repair service
If your repair isn’t covered by Apple’s One Year Limited Warranty, AppleCare+, or AppleCare Protection Plan, your iPhone might be eligible for out-of-warranty service. For example, liquid damage isn’t covered by warranty but might be eligible for out-of-warranty service. Some damage isn’t eligible at all, for example if your device has been broken into multiple pieces. See Apple’s Repair Terms and Conditions for complete details.

Converter-for-class

Is converter-for-class or any other "-for-class" attributes required to match against subclasses of the specified class, or just the class itself?
It you specify converter-for-class as Object, is the converter required to apply to every subclass of Object (i.e. every class), or just to those properties with a runtime value of exactly Object?
Thanks.

Hello BalusC,
thanks for reply. I'm definitely use JSF RI 1.2_13.
The problem is, that the converter-method public String getAsString( FacesContext p_ctx, UIComponent p_comp, Object p_value ) is never called.
But the other method public Object getAsObject( FacesContext p_ctx, UIComponent p_comp, String p_value ) is called.
BalusC, which JSF implementation do you use?
regards, Joerg

Validating a method object whether it is a bean class method

I have a class that is loaded dynamically using URLClassLoader. It is required to validate whether it is a valid bean class' method. i.e. if it is set method, it should start with <set>xxx and if it is get method, it should be like <get>xxx or <is>xxx. I dont want to make it with if conditions and I believe there should be a way to validate if that class satisfies java bean naming specification ( for class/method). Any help is much appreciated.

kajbj wrote:
How would you be able to verify that? Beans can have other methods as well. Well.. in my case, I want to ensure that that does not contain "other methods" and only getters/setters. It should be just a bean and nothing more. There could be cases when a setter method is written like "setTablename" ( note: camel case missing).
I prefer to use this one.
public class Bean {
    String tableName;
    public String getTableName() {
        return tableName;
    public void setTableName(String tableName) {
        this.tableName = tableName;
try {
     BeanInfo info = Introspector.getBeanInfo( Bean.class );
     PropertyDescriptor[] pd = info.getPropertyDescriptors();
     for (int i=0;i<pd.length;i++) {
          System.out.println( pd.getName() +","+pd[i].getReadMethod());
if(pd[i].getReadMethod()==null) {
throw new Exception("Not a bean");
} catch (Exception e) {
e.printStackTrace();
}This code works well, when 1. members not in camel case,
2. methods not in camel case. But when it comes to method , it throws exception for public String getTablename() {
return tableName;
}But it doesnt throw exception for public String gettableName() {
return tableName;
} I predicted exception here. Correct me If I am wrong.

Any hope for Spaces working in PSE 8.0?

I just discovered the power of using Spaces in OS X 10.6.2, and was disappointed to find that PSE 8 is the only program I regularly use that doesn't support this feature. Any hope for this bug being fixed in future updates?

Hi,
I just checked on OS X 10.6.2 that PSE 8 is functional and support the Spaces feature. It is working for me.
Are you observing any specific problem?
Thanks,

Listener for new incoming SMS

Hi,
Can you tell me how to make or use (may be a library ) a listener that can response if an incoming sms received.
Thanks.

What's the listener that listens for new tabs being
added to JTabbedPane?ContainerListener

Is there any hope for us here?

I live in the Caribbean (Dominican Republic). I see the iPhone getting released in a lot of big countries, but I don't see Apple releasing the iPhone in other countries like mine.
I have seen iPhones activated here, but as you know they are being ilegaly activated with the hacking options available, and with every new update the hacks get frustrated.
Is there any hope for the iPhone being released in countries like mine here in the caribbean? What chances do you see for us here? Are we destined to live without the iPhone or with an hacked-outdated iPhone?

The best thing to do is keep watching for announcements from Apple on when the iPhone will be coming to the Dominican Republic, since this is a user to user forum no one would be able to give you an answer.

Help Determining Which Methods/Classes Are Being Used

Hello,
I'm having issues with my company's Java application and because I've luckily narrowed the classes down to a meager 30+ I need some help pinpointing my problem.
I realize there are a lot of Java monitoring applets/applications and some are deployment-specific but I need something very detailed-- I haven't found the features I need.
Specs:
Jrun4, Java 1.4, Windows Server 2003
I would like to have a monitor that tells me exactly (real-time) what classes, methods, variables, etc. are being called in real-time. Looking at the JRun launcher console for one process gives me this:
Generating report:quadbase.reportdesigner.ReportAPI.QbReport with export type:PDF
01/16 14:05:33 error Software caused connection abort: socket write error
java.net.SocketException: Software caused connection abort: socket write error
        at java.net.SocketOutputStream.socketWrite0(Native Method)
        at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92)
        at java.net.SocketOutputStream.write(SocketOutputStream.java:136)
        at jrun.servlet.io.MetricsOutputStream.write(MetricsOutputStream.java:75)
        at java.io.BufferedOutputStream.write(BufferedOutputStream.java:106)
        at jrun.servlet.http.WebOutputStream.write(WebOutputStream.java:64)
        at jrun.servlet.file.FileServlet.pipeData(FileServlet.java:419)
        at jrun.servlet.file.FileServlet.service(FileServlet.java:254)
        at jrun.servlet.ServletInvoker.invoke(ServletInvoker.java:91)
        at jrun.servlet.JRunInvokerChain.invokeNext(JRunInvokerChain.java:42)This is cute, but not really helpful. I would like to determine what was passed to the process, from where and what went wrong.
For example,
Instead of this:
Generating report:quadbase.reportdesigner.ReportAPI.QbReport with export type:PDF
01/16 14:05:33 error Software caused connection abort: socket write errorI would get something like this:
Generating report:quadbase.reportdesigner.ReportAPI.QbReport with export type:PDF
        Page variables: test.jsp ($var1= "I'm"; $var2= "Going"; $var3="To"; $var4="Break"; $var5 = null)
        Calling: test2.jsp
        With: jrun.bin.db.foo.Bar();
01/16 14:05:33 error Software caused connection abort: socket write error
        Problem: $var5 = null;Sorry if I'm rambling, I just want to know what is where and who it's calling when it breaks. Then I could deduce which class, what variable, what page, etc. My application is very complicated and seemingly mundane changes can throw it all off.
Any ideas?

We'll look into usage tracking. We're on the standard edition, so I'm not sure if it's available. Also, some of these reports may be quarterly -- so there may be a long wait to see if the view is used and I need to know fairly soon. (If it's not used, it saves us some work in a project transition going on.)
I certainly don't understand the underlying structure of the product, but it seems like there should be some way to determine if a view is used by a report. I apologize if I'm not using the correct terminology. Thanks for your help -- we'll keep looking into it.

How can I implement a method to get any kind of class I want?

All I want is a method( or a class ) : getClassInstance().
i.e.
Vector v = someObj.getClassInstance("java.util.Vector");
or
Collection c = someObj.getClassInstance("java.util.Collection");
thanks!

Are you talking about this?://example - let's
use Vector
//NOTE - try...catch needed for these.
//Omitted here for clarity
Class myNewClass = Class.forName("java.util.vector");
Object myNewObject = myNewClass.newInstance();
Vector myNewVector = (Vector)myNewObject;
First, thank you very much for your answer!
But what I want is a method that can return any kind of class by input a class name.
Example :(maybe like this)
Vector v = getClassInstance("java.util.Vector");
Object getClassInstance(String ClassName) {
// code
return (ClassName)someObj;
If you have any idea about this question, please tell me the detail. Thanks again!
