java.lang.reflect.InvocationTargetException - help!!!

[gafa]

Hello

I am trying to write a simple program but for some reason I cannot run it.
This is applet.

The only thing I get it is java.lang.reflect.InvocationTargetException and nothing more.

The whole applet code is too long so I want to show you just the class which extends JApplet because the exception happens right in the init() method.

I know the problem is somewhere in classes imports but I cannot find it. :confused:

Please watch my attached file

Normally this error occurs when java compiler finds two different classes with same name in two different packages. When you are importing both classes at a time and create object of that class it throws InvocationTargetException. Did you do that in your application?

Simple solution for this is, when you want to create the object of the class use package name also along with class name. So that compiler can clearly identify them.

Thank you, Eranga

That is the thing I want to do... But I cannot find these "both classes" in different packages :(
Please help me to find these classes. Or advise how to :confused:

Write a simple Java class to read all the file names in your project folder and list them on the console. Simply you can find the matching.

It's greate, Eranga, but i am not sure how :confused:

the project contains so many subfolders...

Is there some standard way?

[gafa]

what if the problem class is in the libs' jars?

Read each folder content, recursively. If you find a file then get the name, else recursively process the sub-folder.

Do you have JAR files in your project as well? If so your simple code no longer simple. You've to process Jar files as well.

One more trick you can try. Using Notepad++ search all files with the extension .java (actually .class if you have jars) within the folder you want.

So maybe I should better use windows search thing with *.java or *.class params ;)
But what should me do with the jars? :confused:

[Eranga]

That's why I told you to use the notepad++, it's capable of searching the zip folders and all such packages. Give a try and see.

I know the java.io.File class but I don't know how to get subfolder with this thing :confused:

[gafa]

Is there an IDE function to look for these duplicated classes?

[Eranga]

I'm not sure that using NetBeans search it's possible to dig into packages. I think it's possible, with the extension.

isDirectory() and list() from the File class.
