Using java.lang.reflect.Method.invoke on a static method?

This is probably a FAQ, but I am finding it impossible to construct a search which answers this question for me.
How do I call java.lang.reflect.Method.invoke on a static (e.g. class) method? Is it even possible?
Thanks,
dwh

Is this of any help?

How to use java.lang.Class.getMethod() and java.lang.reflect.Method.invoke(

I want to call a specified method of one class dynamically. I use the method
"getMethod()" in package "java.lang.Class" to get method and "invoke()" in
" java.lang.reflect.Method " to invoke method.
The problem is as following :
1. There are two argument in this method "getMethod(String MethodName , Class[] paremterTypes)" in package "Class". I have no idea about the second parameter " Class[] parameterTypes ".what does the argument exactly mean ?
2. There are two argument in the method "invoke(object obj, object[] obj)" in package "Method".
I have no idea about the second parameter "object[] obj ".what is mean ?
I pass " null " value to it and it works.But i pass anothers ,jvm will throw exception.

I have a generic Method Executer that has a method like
public Object execute(String className, String methodName, Object args)
    String fullClassName = packageName + className ;
    Class delegateClass = Class.forName(fullClassName);
    BaseDelegate delegate = (BaseDelegate)delegateClass.newInstance();
    Method method = null;
    if (args == null)
        method = delegateClass.getMethod(methodName, new Class[] {});
        obj = method.invoke(delegate,new Object[] {});
    else
        method = delegateClass.getMethod(methodName, new Class[] {args.getClass()});
        obj = method.invoke(delegate, new Object[]{args});
   }This seems to have problems when I call the method from a class like:
execute("CategoryDelegate", "getCategoryById", new Integer(4144));(I get a NoSuchMethodException)
The method I am trying to execute in CategoryDelegate looks like:
public Category getCategoryById(int categoryId) throws DelegateExceptionI think it has to deal with the difference in the way we handle Primitive Wrappers and Objects. Wrapper we have to use Interger.TYPE and with the rest of the Objects we have to use obj.class.
Am I doing something wrong here? Any suggestions to make it work for primitive wrappers as well as Objects?

Using java.lang.reflect.Proxy class

I am investigating the uses of the new Proxy object introduced in jdk1.3.
One of the first things I noticed was how slow it was to generate a class via Proxy. The system can spend over 100 millliseconds to generate one. If you create many of those this can suck up alot of time. Is there a way to speed this up? I noticed when I try to cache the Object sent back into one of the java.util Collection I get errors when trying to retrieve them. Usually class cast errors when I call the 'isEmpty' method on the Collection.
I noticed that I could cache them into an array of Objects, I have also been able to store the Class that is generated, and the Constructor, so when new ones were needed I could just call the constructor using the Class that was pre generated.
In my performance tests it took in the order of 2 minutes to generate 100,000 without any cacheing.
When I cached the objects in an [] of Objects that time went down to around 15 seconds. When I cached the Class and Constructor the time went to around 30 seconds.
Has anyone out there attempted to cache Proxy's?
I would appreciate any experience you have had with this.
thanks in advance
chris

Cris,
I am very interested in the caching approach you took. I have an application that uses a lot of proxies, any kind of optimization on proxies would result in a big performance boost.
Thanks,
David

Perhaps the Solaris JVM has a lower stack size by default.

your error seems to indicate that your embeddedLdap isnt in sync with the Database ? Did you either delete files from your file systems or cleanup the portal db or finally used a copy of some existing database for your domain?

What this error mean. Help! I dont understand. The program is running when I try to run it but when I try to deploy it using JNLP it wont work.

Hi,
I get the same error and i am not really sure what your explanation says... This problem below is the latest of a series of problems i started getting after i updated my BIRT version in Eclipse 3.3.1 and RAD 6.0... I troubleshooted and resolved most of them however i am not sure and it is not obvious to me what is required for this particular one below
In the problems tab there is nothing to give me a clue. The exception below appears in the Websphere console and also on the page when trying to access my jsp file normally. I am not sure what is causing it, but here it is:
JSP Processing Error

One of the funny things here, is that this is happening only when i start websphere in debug mode!
Does anyone have any idea of what may be causing this or how we can find what's causing it or how to resolve it??
Thanks in advance

Exceptions details : java.lang.reflect.InvocationTargetException

I have set up a web service.
Development environment:
1 java 5.0
2 jwsdp 2.0
3 Java system application server 9.0
I set up the web service by following these steps:
1 write endpoint application source code
2 write build file and build properties.
3 use asant command compile the source code (successfully)
4 use "asant generate-runtime-artifacts" generate web service artifacts(successfully)
5 use "asant pkg-war" to package war file. (successfully)
6 use "asant deploy-app " to deploy the web service. (successfully)
So, I can find my webservice in administration console. I click the test button, it pop up a webpage, in which I can input parameters for my web method.
After inputting all the parameters, I clicked the button to invock my web method. But some exceptions occured.

Java.lang.reflect.InvocationTargetException

Hi,
I am new to EJB. i've developed my first EJB Program using Netbeans.
Here are my classes :
package ejb;
import javax.ejb.Stateless;
@Stateless(mappedName="Bean30")
public class Bean30Bean implements Bean30Remote
public String getResult()
return "This is EJB 3.0 Bean";
Remote Interface :
package ejb;
import javax.ejb.Remote;
@Remote
public interface Bean30Remote {
String getResult();
Calling EJB :
InitialContext ctx = new InitialContext();
Bean30Remote br = (Bean30Remote) ctx.lookup("Bean30#ejb.Bean30Remote");
System.err.println("EJB message is: " + br.getResult());
While lookup, it is throwing me an exception :

I've checked on the GlassFish. It has been deployed successfully with name "EJBModule30".
Any comments will be greatly appreciated. Please let me know if i'm doing something wrong.

In any case the name inconsistency is a nice catch, but when I check the logging:

Java.lang.reflect.InvocationTargetException Caused by: java.lang.UnsatisfiedLinkError

Hi all,
I'm using jdic web browser (windows version) and customizing it for a project. I want to make an executable jar file. Since I'm using NetBeans 6.7.1, I'm getting a jar file in dist folder. Bt when I run it it does not open the jdic browser.
Then I tried java web start and make a jnlp file. When it tries to run I get the below error..

thanks in advance

Yeah..! it's working :)
I just copied jdic files (jdic.jar,jdic.dll, IeEmbed.exe etc) into dict/lib/ folder and now it is working.

i searched for the solution which says that it is becoz of the soap but i haven't used soap.
So please help me for this

Clear JAVA Caches.
Try this:
1) Go to Applications >Utilities > Java > and startup Java Preferences
2) Under General Tab, go down to Temporary Internet Files section and click "Settings..." button.
3) In the Temporary Files Settings window, click the "Delete Files.." button. Click Ok and quit application.
4) Download your FCS Java Client Application again from your browser (http:// YOUR.IP.ADDRESS/finalcutserver) and install as usual.
Good Luck!

Java.lang.reflect.InvocationTargetException when launching ESB

Hello,
I'm getting a java.lang.reflect.InvocationTargetException when launching ESB. I've tried restoring the archives and generating new signatures, clearing my local java cache and restarting the server.
I'm running NW 711 SP06 and are using Java 1.6.0_14-b08 on the client (actually the same system). This used to work and the integration directory works fine.
The full exception is below.
Thanks (and points) for any ideas.

A workaround: starting with the repository.jnlp file from a system where the ESB was working, I replaced all of the references to the server address, port and SID to point to the server that wasn't working and saved the resulting repository.jnlp. Clicking on that jnlp file launched the ESB without error.
I still don't know the root cause of the problem, but this seems to be an acceptable workaround for now.

AxisFault: java.lang.reflect.InvocationTargetException

Hi all,
this is really really weird.
I am having a service, where I send files and an own datatype to.
Well, this all works very fine (after lots of "trial/error" ;-) ).
But now, I want to use jacksum to compare the checksum of the transferred file and before and after the transfer.
The strange thing is, the code works when I run the service as a java application.
But when I call it from my client I get an error in a row which definetly is not wrong!
The error is (well, this error message really didn't help me at all!):

I can tell you, that all the jars needed are there, because without calculating the checksum the service is called without an error.
And on the other hand, trying to run my web service as a java application, this works fine aswell.
Hope, anyone can help me, because I'm really stuck in that problem
Thanks a lot in advance!

Yeah I have to agree, it was pretty simple and if you dont understand the concept of a build path within an IDE you probably should be reading some more basic tutorials than those centered around web services.
That wasnt meant as an insult either, but I doubt you would really understand what it is that you are doing.
Lots of things could cause an invocation target exception, not just a missing jar file so if you are getting this exception the solution on this page could well be wrong in your situation.
You should look for the actual cause of this exception on your application server where the web service in exposed from, and\or read the javadoc below.

Java.lang.reflect.InnvokationTargetException

Hello everybody,
I am getting following error logs while executing my swing application.
java.lang.reflect.InnvokationTargetException
at sun.reflect.delegatingMethodAccessorImpl.invoke
(DelegatingMethodAccessorImpl.java:25)
at java.lang.reflect.Method.invoke(Mehod:java:324)
I am trying to call some class's method using reflection principle.
All values of acces modifier, return type, method name, args are correct at run time. I don't understand why i am getting this error.
Can anybody please help me.
Thanks and regards
Girish Varde

I would say that this sentence is rather confusing since you get the exception nonetheless.The sentence means when I am in debug mode and check value of the actual class whose method is called, the class value is correct. It's not that the class whose method I am calling does not exist.
First I give the reference error log which you can use to locate at what point the exception is thrown.

JSWDP 1.1 - wsdeploy error: java.lang.reflect.InvocationTargetException

Ok - All help is really appreciated!
I'll get the configuration questions out of the way first...I'm using:

I've been able to successfully run the "Hello World" example provided by the JWSDP 1.1 tutorial. I'm now trying to generate a WSDL using an interface that had worked with JWSDP 1.0 EA, but I'm getting the following error:

try just using the wscompile.bat/.sh commandline tool first. It will automatically setup the classes used
by wscompile and jaxrpc, you will only then need to specify the classpath to your classes on the
commandline. This might help you isolate the problem so you can fix the ant tasks.

JNI: java.lang.reflect.InvocationTargetException

I am trying to use JNI, however, when I try to access it from a non-static class it throws an java.lang.reflect.InvocationTargetException. I think I've narrowed it down to the System.loadLibrary() method. Does anybody know why this could be happening?
Thanks,
Jeremy
