Hi,
Perhaps you need to create a setUser function inside the Main.java file ?
:-)

Subject: Problem with example ComponentCommunication
Hello experts
I am new in Java and WebObjects. Following the manual "Web application" I
got a problem with the project ComponentCommunication.
Build und Debug reports an error in the file UserEdit.java on line
nextPage.setUser(user);
Error: cannot resolve symbol: method setUser (User)
Where is the bug???
Correctly working copies of the three java files
// User.java
// Main.java
// UserEdit.java
would also help greatly to me (or a hint where to get them).
Thanks for any help
