I am trying to use a custom tag in a jsp page but I get compilation errors so far. Here is the custom jsp tag code along with the jsp page that is trying to use it.

And here is the error log that Netbeans give me when it tries to compile the custom tag :

/Users/skiabox/NetBeansProjects/simplewebapp2/nbproject/build-impl.xml:612: Java returned: 1 BUILD FAILED (total time: 2 seconds)
As you can see the first error occurs when the code is trying to access addressBean.state Any ideas on how to fix that or what am I doing wrong? Thank you.
I know it is very late (over 3 years) to answer this question. I have also had this problem. Apparently the solution is "Clean and Build Project" or press SHIFT+F11 and run again the project.
