Hi,
I'm setting up two servlet classes:
issueOptions() (in issueOptions.java) and menuUI() (in menuUI.java).
Both are in the same package: menu.
menuUI has a method inside called issueOverview().
I want to call and execute the issueOverview() method from the issueOptions
class, but how do I do this? I have been trying to do by creating an
instance of the menuUI class, but I cannot be doing correctly. I have
posted the following code (which I hope is useful) and the error produced
upon compiling:
menuUI.java
