Struts Action Issue
Hi,
Recently I observed that if in JSP input text I have entered special
characters, lets say:
displayIDNumber: #$!@#%$!#$%!(*)&*()*(&
In the action I get displayIDNumber as "" i.e empty string.
Nowhere in the code we are explicitly emptying the string whenever there are
special characters in the input string.
I puzzled. Can someone please clarify?
Thanks in advance!!

One way we can help keep the documentation up-to-date is by filing a
CLA. When we run across an obviously ancient page we can then delete it,
or at the bare minimum file a JIRA issue against the offending page.
It's also good to make sure when we post answers that we're posting
relevant (and at least marginally current) information.
The page in question was deleted almost immediately after you posted the
reference (by at least two people, although someone else beat me to the
punch): pages with zero incoming links aren't often visited, and we
don't always know they're still there until somebody references them for
whatever reason.

That doesn't make any sense. That link is outdated (very) from the
webwork days. Forms can use either POST or GET.
@original poster: add breakpoints to the ParametersInterceptor and see
if your params are getting filtered out by it.

Hi,
I followed the replies but could not resolve the issue. Another update I
have is this request is an Ajax.Request with method = 'get'.
Can this cause any trouble? Changing get to post however does not help.
Please advise.
Thanks!

agree with Rommel
a FieldValidationInterceptor would accomplish this objective
http://struts.apache.org/2.0.14/docs/fieldexpression-validator.html
HINT place validation logic in expression validator e.g.
<param name="expression"><![CDATA[#myField <> '']]></param
Unless you're using Hibernate or iBatis (or any ORM which will create SQL Statements) I would strongly suggest your DBA to place Triggers to validate Data inserts before pushing into DB..(Once the aberrant character is in your DB there is no extracting)
I would also suggest incorporating jsp precompile jsp's into your build cycle to catch
any misconfigs in tld's

Riya,
I'm sure that if you trace the request submission from JSP to your Action class
by debugging it step by step you will find where the culprit will be. I had one experience
before that took me hours to figure out whats wrong in our JSP page where its not showing
block of data. After debugging step by step, the logic that checks for the string to show the block of
data had a trailing empty character. That string was saved in the database with the trailing space char.
and when we pulled it and check for the matching string, our JSP was screwed up. So just a note
always trim the data(String) you push to your database.
Goodluck on the debugging spree :).
Rommel

Out of curiosity, I gave the same value in my application and tested, I got
the exact junk back in my action not even a truncated one. So, please check
whether ur action bypasses only this kind of string or even valid string
like "test" or "sample". If it doesn't show valid string then there is
problem with view file field name and action variable name. If valid strings
are working fine and only this kind of string seems to be a problem then
please generate the issue in a small testcase and send it across.
Thanks,
Muthu

Hi,
Recently I observed that if in JSP input text I have entered special
characters, lets say:
displayIDNumber: #$!@#%$!#$%!(*)&*()*(&
In the action I get displayIDNumber as "" i.e empty string.
Nowhere in the code we are explicitly emptying the string whenever there are
special characters in the input string.
I puzzled. Can someone please clarify?
Thanks in advance!!
