java.lang.Noclassdeffounderror: Caused by: java.lang.Classnotfoundexception: When run . jar

Question

I am developing in Netbeans IDE when running through the IDE everything works fine but when I do clean and build and create . jar while executing casts me this exception:

I tried to compile package by package but it still didn’t work.

Any suggestions to fix this problem?

Editing this is the class that the bug says is missing, I already checked and the file . class is in the jar, Is there an error that the compiler cannot catch?

        }

    public void limpar() {

        lotes.clear();

        fireTableDataChanged();
        }


    public boolean isEmpty() {
        return lotes.isEmpty();
    }

}

After that I make normal use of it:

jTblLinhasOnline.setModel(new LoteEstadoTableModelTESTE());

Hang on, you can help me?

Issue 2

I copied the class for the class SoftwareGui and it worked, yet if anyone knew the other resolution they preferred...

Answer 1

In this case the problem was in the netbeans cache.

This is the directory:

C: Users jsan7os1991 Appdata Local Netbeans Cache 8.0

All files must be cleaned.

Answer 2

The exception NoClassDefFoundError is launched when the JVM is not able to find a particular runtime class that was available at compile time, for example, if a method or any static member of a class is not available at Runtime, NoClassDefFoundError is released.

It is important to understand that NoClassDefFoundError and ClassNotFoundException are distinct exceptions, the latter is thrown when trying to load a class through the name, through the methods ForName class Class, loadClass and findSystemClass class ClassLoader. This happens when no definition for the given class name has been found.

Exception in thread "main" java.lang.Noclassdeffounderror:

This error is usually linked to classpath which may not be configured or referenced correctly. You even checked if this problem happened by specifying the class path using the option -classpath or -cp?

It may also be likely that the cache data might have been corrupted due to some Crash that the IDE suffered, it clearly justifies the strange behavior that Netbeans has had according to his commenting.

In the Bugzilla has something similar to this situation, but occurs in another version(6.x), the solution found was the same as yours, delete the cache.

Answer 3

Looking at the solace you’ve glued, the JRE is complaining of the following class:

gui.tabelaLinhasonline.TesteLoteEstadoTableModel

However, the code you pasted is of the following class:

gui.Admin.LoteEstadoTableModelTESTE

Search your code for occurrences from the first class (the one you launch ClassNotFoundException) and replace by the second.
