Question

I have my own IlvObjectInteractor. When using this interactor, I receive the error "can't find or create interactor nameOfInteractor." What should I do?

Answer

There are two possible causes for this: class visibility or ClassLoader issue.

Class visibility: Your class might not be visible inside the ilog.views package. The problem generally results from the absence of a public keyword before your class description, when it has only a package visibility.

ClassLoader issue: There are two ways to influence the class loader used by ILOG JViews to load a class from CSS:

  • Set the classloader of the current thread. Something like the following:

    Thread.currentThread().setContextClassLoader(desiredClassLoader);

    The context class loader is not set correctly during the initialization of Eclipse plugins by default; therefore you have to do it yourself. This is documented in the Eclipse FAQ at http://wiki.eclipse.org/FAQ_How_do_I_use_the_context_class_loader_in_Eclipse%3F

    This context class loader is also used at other places in JViews.
    This option is recommended.

  • Call setClassLoader on the particular IlvCSSBeans class used to interpret the CSS file.
