java.lang.Class for current file in editor

Please, someone throw me a bone here.

How can I get it if it exists? Currently I'm trying to create an
URLClassloader with the module's classpath and loading the class that way
but it isn't working. Is there a way using psi?

Hi,

PsiClass is the same meaning object for IDEA (during editing) as
java.lang.Class for java VM (during running) and should provide
reflection on fields/methods/etc.
I wonder what kind of other stuff you are going to use with
java.lang.Class.

Given that you need to get PsiClass for active editor and have a
'project' instance this looks like following:

final Editor selectedEditor =
FileEditorManager.getInstance(project).getSelectedTextEditor();
final PsiFile file =
PsiDocumentManager.getInstance(project).getPsiFile(selectedEditor.getDocument())
;

if (psifile instanceof PsiJavaFile) {
PsiClass[] clazzes = ((PsiJavaFile)psifile).getClasses();
if (clazzes.length > 0) {
// note, there could be more then one class in the file
// one needs to find public class or class with name = name of
// file w/o extension
// so adjust the index accordingly
System.out.println( clazzes[0].getQualifiedName() );
}
}

Thanks for the reply but...

I NEED +java.lang.Class +to pass to ObjectStreamClass::lookup(java.lang.Class). This is for the GenerateServialVersionUID plugin and once I get an instance of ObjectStreamClass I can use its +getSerialVersionUID() +method instead of using the serialver.exe tool, which is what I'm doing now.

Hi,
Thank you for the clarification, in this case PSI is of now interest for
the task. Maybe project/global libraries are missed from the classpath
of your ClassLoader.

I know I'm getting the correct classpath because I can use the same
classpath for the serialver.exe tool and it works fine. But, I may not be
creating the urls for the URLClassloader correctly.
I've tried several different formats but here's what I'm trying now (doesn't
work obviously):

i have no real experience in this subject but as far as i remember, jar files have their own protocol.

I would guess that using

where dir is a file with jar extension doesn't do what you want.

have a look at http://javaalmanac.com/egs/java.net/JarUrl.html?l=rel it may help

Thank you! Thank you! Thank you! I thought I had tried that format already
but must have had something wrong.
