RE: Cannot create ActionForm
Personally I would log this as a bug
org.apache.struts.util.RequestUtils.createActionForm(RequestUtils.java:844)
should *not* be allowing nulls as string
Anyone else ??

Hi, Sebastien.
This might be caused since Struts logs what bean it created and is going to
populate. Turn off the RequestProcessor's log4j category and the call to
toString() should be gone.

RE: Cannot create ActionForm
I traced it to a nullpointerexception. Didn't know why Struts is calling
toString() which throws NullPointerException. Anyway, it uncovers the
bug in my toString.

RE: Cannot create ActionForm
Hi, Sebastian.
It looks like the call to new FileForm() throws an exception.
Have a look at your Tomcat logfiles. There might be more information about the JSP
compiler failing.
If that is not the case, check that the class exists (class name/package name).
If it is the first instantiation in your application, it might be a class loading
problem. Maybe another class FileForm relies on cannot be found.
If it is a second, ... instantiation check what code runs in the default constructor.
This is what I'd go for.

RE: Cannot create ActionForm
Hi, Sebastian.
Seems like Struts cannot create an instance of your FileForm class. Something must be
wrong during (class) construction.
Do your log files reveal some more information?

Cannot create ActionForm
Hi
What can go wrong when this is thrown?
javax.servlet.ServletException: Exception creating bean of class
sg.edu.astar.flamingo.web.proteomics.form.FileForm: {1}
FileForm contains some FormFile variables and I have the correct enctype
in my JSP already.
Tell me if codes are needed before I posted them.
Thanks
