[ANN] Struts Q&A Distilled, Vol#2

[John Yu <jo...@scioworks.com>]

"Struts Q&A Distilled" is a catalogue of question-and-answers distilled 
from Struts mailing lists and other sources. The catalogue is organized in 
topics. New entries are added to the catalogue periodically in batches.

Volume #2:

      http://www.scioworks.net/servlets/ShowPage?pid=34&dp=3

Covers:
Q1: It is recommended properties of the FormBeans should be String 
properties. In that case, where do I do the type conversions?

Q2: How much does Struts depend on the session object and when is the 
object created?

Q3: I have problem with using ActionErrors and <html:errors>. I don't see 
my messages. Why?

Q4: My error messages generated by <html:errors> contain "null" at the 
start and the end. What have I done wrong?

Q5: How do I prevent my form from being validated when it is displayed the 
first time, if the JSP is fronted by an Action?

Q6: Struts 1.1 seems to support multiple resource bundles. How to use it?

Q7: After I replace my <input type="submit"...> to <html:submit...>, my 
Javascript document.forms[0].submit() does not work anymore and returns me 
"Object doesn't support this property or method". Why?

Q8: How do I configure Struts to intercept requests and perform some logic 
before passing them to the controller servlet for processing?

Q9: How do I send binary data to the controller servlet? (e.g. a 
Swing-based client sends serialized object to the controller servlet.)

Q10: I want to associate data with <html:check> and return the selected 
value as a String property in the FormBean. But I got exception coming from 
RequestUtils.populate(). Why?
