expression "#{mybean.myfile} to a new value of type

"org.apache.
myfaces.custom.fileupload.UploadedFileDefaultMemoryImpl" to type

entire example in this post. I'm using Tomahawk 1.1.3 with RI JSF created
in Borland's JBuilder. I've created a .war file from borland and deployed
it under Tomcat 5.5 so it should be Borland independent. The problems I was
having previously were in trying to deploy Tomahawk on a old JSF project.
I'm pretty sure I'm safe in saying you must use JSP 2.0 and Servlet 2.4 as a
minimum.
inputFileUpload/Tomahawk specific elements are bold/italic
In the backing bean WelcomeBean.java, I only read the uploaded file into a
byte []. In my personal application, I simply insert the byte [] into an
Oracle BLOB. You may need to write it to a file. I'll assume you know how
to do that.
I think that's pretty much it. If you have any questions please respond to
this post. I'll receive an e-mail and try to help. If you want to know how
to implement Tomahawk 1.1.3 into Borland's JBuilder, I can help with that
also I believe.
Doug
