Bean tag lib help

2003-08-06 Thread Vance Heredia


Hello,

I got a question.  My struts-bean tag doesnot seem to work correctly.

Everytime I use the Bean tag

Eg  bean:define id=processName name=filesForm property=processName/

I get a 

java.lang.ClassCastException
at org.apache.struts.taglib.html.FormTag.lookup(FormTag.java:766)
at
org.apache.struts.taglib.html.FormTag.doStartTag(FormTag.java:481)
at org.apache.jsp.files_jsp._jspService(files_jsp.java:149)


The Java code looks like 

  _jspx_th_html_form_0.setParent(_jspx_th_html_html_0);
  _jspx_th_html_form_0.setMethod(POST);
  _jspx_th_html_form_0.setAction(/files);
  149-  int _jspx_eval_html_form_0 = _jspx_th_html_form_0.doStartTag();
  if (_jspx_eval_html_form_0 !=
javax.servlet.jsp.tagext.Tag.SKIP_BODY) {
do {
  out.write(\r\n  );
  /*   bean:define  */
  java.lang.Object processName = null;
  org.apache.struts.taglib.bean.DefineTag _jspx_th_bean_define_0
= (org.apache.struts.taglib.bean.DefineTag)
_jspx_tagPool_bean_define_property_name_id.get(org.apache.struts.taglib.bean
.DefineTag.class);
  

Doea anyone have any ideas how to fix it

Re: force precompilation of JSPs

2003-08-06 Thread Alen Ribic

If you are using Tomcat.
%TOMCAT_HOME%/bin/jspc can do this.
read your Tomcat documentation for instructions.

For other look at vendor specific documentation for clues.

OT Friday: Play build

2003-08-06 Thread Vic Cekvenich

http://sourceforge.net/project/showfiles.php?group_id=55539release_id=176296

This is a struts.jar build, using a nightly build source, targeted at 
JDK1.4 (j:Rockit RT.jar; not JDK 1.3) and Servlet 2.4 (Tomcat 5, not 
Servelt 2.2) w/ late antlr.jar and minor touch ups.

To play, I removed struts.jar in basicPortal, and replaced with the new 
jar... everything worked.
Why I did this... Iduno.

Note: I would not use this in production.
Late build/release of bP and Jasic use the old Struts 1.1 jar (1.3 jdk, 
2.2 servlet)

RE: Hindi i18n Iscii Font

Subject: Re: Hindi i18n Iscii Font

Hi Kiran,

You need to set the character encoding for the JSP page/response.  Java
still thinks the response should be in the default encoding which is
ISO-8859-4 (I think that is the Latin character set).

I use UTF-8 encoding so that I can mix languages eg
English/Japanese/French without having to worry about setting the
correct page encoding for each page.

So I do the same thing for the properties files eg

 native2ascii -encoding UTF-8 etc etc

But at the top of each of my JSP pages I have this:

 %@ page contentType=text/html; charset=UTF-8%

In your case you probably have to change that to charset=ISCII91 if use
that encoding.

You can put this in your base action so you don't have to include in
every page eg response.setContentType(text/html; charset=UTF-8).

[Note: JSP Precompilation:
The only problem I had with setting the content type in the action was
when precompiling JSP pages.  If there this line
 %@ page contentType=text/html; charset=UTF-8%
isn't in the JSP page or page fragment then Jasper would use the default
encoding instead of UTF-8.]

You will also need to set the character encoding on any request that
submits data otherwise it will also be interpretted as ISO-8859-4.  I
use a filter an all request that just does this:

 request.setCharacterEncoding(UTF-8);

(again change this to your character encoding ISCII91)

This can't be done in an action because form beans are populated before
they are given to the action.  So you have a choice of using a filter,
or overriding the RequestProcessor to do this.

Hope this helps.

Re: DynaActionForm BUG?

2003-08-06 Thread Adam Hardy

Hi Amin,
what do you mean by a multibox or set of checkboxes? I am not familiar 
with the terminology. I presume you have a set of checkboxes for a range 
of dates.

I have a big form with a number of multibox tags. It seems that there
are mixup of data from one multibox to another. Is this a documented
bug or does it have to do something with jvm or tomcat? I have tried
on solaris and windows xp both environments seem to have the same
problem


Do your multibox tags have the same name? How are you generating your
multiboxes, and what is the resultant HTML? What are the results of
inspecting the enumeration of request parameters that are being received?

RE: Best place to hook the Security Call

2003-08-06 Thread Viral_Thakkar

I have an authorization requirement as below. 

1. A user can have a role for a specific company. 
2. A user can have many roles for a specific company. 
3. A user can have different roles specific to different companies. 
It means a user can have few roles for Company (lets say ABC Inc.) and
can have few roles (same or different) for some other Company (lets say
XYZ Inc.) 

User Access level changes for each request depending on the role and the
company (company, which exist at that point). 

Please help in suggesting the authorization framework I can use for such
requirement.

Can SecurityFilter component help me in implementing this requirement?
If yes, how..??

Thanks..

This is what I mentioned earlier.  We needed more security flexability
that
what the normal servlet container supports so we had to write our own
security handler.  The struts framework has a method hook in the
RequestProcessor class that will allow you to verify the users access
rights
for each request.  The method is processPreprocess.

I agree with Alen, but at the same time if all the containers are
supporting J2EE security standards then porting to different containers
should not be an issue. SecurityFilter as I just browsed through seems
interesting but all the latest J2EE containers will have to support
Servlet
2.3 for using the same. Alternatively whatif I write my own security
piece
by looking up LDAP for AA (authentication and authorization) and this
piece would be called from some place in the STRUTS control flow so that
for everyrequest security would be validated.

If I'm not mistaken, this approach is container specific hence would
make
deployment on difference container(s) not as smooth as one would wish.
I may be wrong so please correct me! I'm not very clued up in this area.
;)

I have privilege working with servlet 2.3 and am now using
SecurityFilter
component (www.securityfilter.org)  to handle my auth. Very simple!

--Alen


Best place would be using container J2EE security, such as JDBC realms.

Re: Still struggeling: howto get ActionForward to calling page

2003-08-06 Thread Adam Hardy

The input attribute on the action mapping is what you specify for the
return page when validation of the form bean fails, so that is not going
to help you.

The easiest solution I can think of is to put a hidden field in your
selection screens with the screen's URL in it.

Alternatively you could try using the HTTP header referer e.g.:

Referer: http://www.w3.org/hypertext/DataSources/Overview.html

but this is an optional header so not all browsers have to send it. I've
never used it so I don't know which browsers do send it.

Hi,

i am still looking for a clean way to get an ActionForward to the page that called my
current Action. That means e.g. I am a displayListAction and have been called by a
selection screen. In case i don't find a result for the selection parameters I would like to
bring a specific error to the calling selection screen. That would give users a chance to
change their selection.

Sounding easy, this gets complicate in case there are several selection screens
bringing up the same list. I don't like to create a specific forward for each selection page
and then somehow determine which one called me (can do that, but there should be a
nice way in such a famous framework?).

The hint using
ActionMapping.getInputForward()
or new ActionForward(mapping.getInput())
didn't help me to much, seems to me there is hardcoded value inside, specified in the
input attribute of the specific action.

How would an expert solve that problem?

:-) Alex

Looking for a way to get an ActionForward to the page calling the
current page.

The example:
Want to realize 5-XX pages where to enter values for a
calculation. The calculation result page would check if
everything was fine (using db queries etc..)
Now in case that one of the input values is incorrect /
missmatching the context, I'd like to redisplay the calling page
showing the values entered before + an error message.
