RE: JavaScript / struts submit problems

2003-01-28 Thread Mei Zhu 
In your Action class you have:
 sXML = request.getAttribute("XMLQueryString").toString();
this will throw a NullPointerException, because XMLQueryString is not a
request attribute but a request parameter. I have tested using
XMLQueryString, I did notice that the value cannot be populated to the form
bean from request. If you don't mind, you can send me your new files with
xmlQueryString as property name. I will be glad to look at for you.

I dont think that the capitalization is the problem, I have tried to do it
with the get and sets like XmlQueryString() and the property
="xmlQueryString", and I still get a zero length string when I try to
getXmlQueryString() in my action class.

It is obvious that struts does not populate the form bean value from
request
if you name your property like "XMLQueryString" (but it can be populated to
your input field from form bean). I do not understand exactly why. If you
just want to make it work I would not use a property name with the first
and
second charaters being uppercase, e.g. in your jsp page, use
property="xmlQueryString" while in your form define methods
getXmlQueryString(), setXmlQueryString().

Just to add another note, it may not work(you need to verify by looking at
Java Bean spec) if you define your property name like xMLQueryString, but
xmlQueryString will work.

Hello All,

I am having a little problem that hopefully someone can help me with.  I
have a form that has a hidden field in it, I am not populating this hidden
field on the page load but rather I am populating the value in a JavaScript
function and then using the form.submit() in JavaScript to submit the form.
When I try pulling the value for the hidden field out in my Action class I
get either a null pointer exception or a zero length string depending on
how I try to get the data.  I have verified that there is data populating
in the hidden fields value.  Here is the code below, if anyone can help me
in finding out how to get the value I would be very grateful.
