Re: [QF-Test] Problem with importing

Hello Shi,

the OSGI-based class loading and Jython's concept of where to find
classes don't go together well. QF-Test initializes Jython's class
loader based on the SWT class loader, so it can load those classes,
but it doesn't realize that, thus the import errors.

The best way to import a Java class in a Jython script in an
Eclipse/RCP based appilcations is to get hold of a ClassLoader that
can load it and use loadClass. E.g.

# get hold of any SWT component
shell = rc.getComponent("Workbench")
# get its ClassLoader
cl = shell.getClass().getClassLoader()
# use loadClass instead of import
Tree = cl.loadClass("org.eclipse.swt.widgets.Tree")

Best regards,
    Greg
