html:image - running into an infinite loop
Hi,
I have read old mails regarding the html:image implementation and the
recommendations related to identifying which image is clicked in the form. For
reference is used Ted's - 'Struts Tip #1 - Use an ImageButtonBean to represent
an image button' @ http://husted.com/struts/tips/001.html
My problem is a step further in the same. I will try my best to explain it, I
hope I get it right.
I have a mainpage which has many image buttons, they all map to different
actions that they must perform. Once the image is clicked, I identify the image
and perform the relevant action by forwarding the call to the relevant action
mapping. Most actions have a .jsp (UI) and action class and are defined in the
struts-config.xml part shown below:
struts-config
form-beans
form-bean name=dataForm type=com.data.struts.form.DataForm
/form-bean
/form-beans
global-forwards
forward name=getData path=/getData.do/
forward name=resetData path=/resetData.do/
/global-forwards
action-mappings
action path=/getData type=com.data.struts.action.DataAction
name=dataForm scope=request input=/jsp/dataForm.jsp
forward name=success path=/jsp/dataForm.jsp/
/action
action path=/resetData type=com.data.struts.action.ResetDataAction
name=dataForm scope=request
forward name=success path=/getData.do/
/action
/action-mappings
message-resources parameter=ApplicationResources/
/struts-config
In my case DataAction class receives the click event and forward the call to
/resetData.
//as below
if (dataForm.getRestButton().pressed() errors == null) {
Log.debug(RESET BUTTON :+ dataForm. getRestButton ().getName()
+, X : + dataForm. getRestButton ().getX()
+, Y : + dataForm. getRestButton ().getY());
return (mapping.findForward(resetData));
}
The ResetDataAction process the request (does some thing) and must return back
to the caller - forward to /getData finally.
//as below
mapping.findForward(getData)
All button handling working fine and I can do the processing in ResetDataAction
but the problem start when I forward the call back to /getData. The call forward
to DataAction class but the button click is identified and the call gets
forwarded back to /resetData and then back here I get into a loop.
I tried to reset on the form (which is common to both action classes) but no
success, I tried explicitly setting the button beans X Y values to null, still
no success.
What I could do was do the process I was doing in ResetDataAction in DataAction
but that is not what I would like to do.
I want to keep the two implementations separate as one only delegates and the
other does some processing. Can someone throw more light onto this? I have been
reading a lot but have not come across a person who faced a similar problem. It
may be something really basic but I can't solve it the way I want and it's
bothering me.
Any help on this will be much appreciated.
Thanks in advance,
Anuj

Re: html:image - running into an infinite loop
The problem you are having, is that each time you forward to an action then
struts will re-populate the form from the request.
That is why you are getting into a loop - when your ResetDataAction
forwards back to getData - the action for getData is having the form
re-populated from the request, including the x, y co-ordinates.
If you did a redirect then you would effectively get a whole new request,
but you would loose everything, not just the x, y co-ordinates.

Re: html:image - running into an infinite loop
Niall, Thanks for the help. Atleast now I know where to look to solve the
problem.
My next question, how to remove / reset the button parameters (x y) in the
Request?
I need the other parameters to stay (sort of refresh / repost, but don't want to
go back to 'ResetDataAction') .

Hi All, I am validating email address entered by user, using in validate method of formBean. If the email address is invalid I am adding the errors.

RE: Validate method going in infinite Loop
hi,
well then..
do not perform any validations in the validate method. (leave it
empty).
do this email validation in the action class. so if ur email is
invalid add that to errors and also get other data from db and then
forward to jsp.
so this will display both ur error and other db data
make sure u create the errors object as usual and u shoud save those
errors to the request object using
saveErrors(errors,request)

I am working on a very tight project and have myself proposed struts implementation.

Re: Validator going into infinite loop
Hi David, I'm using Struts_Validator-2001100702.jar with Struts 1.0. I am confused about how to make this work, so I turned the automatic validation off and validated it manually in my Action class, the same way as in the multipage form example. I'm not sure where I went wrong, but I had troubles setting it up with input=/survey.do. Validation worked when I set input=/survey.jsp. -Mike On Thu, Sep 20, 2001 at 08:08:05AM -0700, David Winterfeldt wrote: What version of Struts are you using and what version of the Validator?

Re: Validator going into infinite loop
I didn't pay attention that you had your input set to the action. Since you had valdiate=true, it would try to validate before the Action's perform method was called, but if validation failed it would try to go to the action again. So it would validate, fail, go to the action, etc. David --- Mike Bridge [EMAIL PROTECTED] wrote: Hi David, I'm using Struts_Validator-2001100702.jar with Struts 1.0.

Re: infinite loop
Are you using extension mapping, with the extension .cm? If so, then your
infinite loop is happening because you are forwarding from the action right
back to the same action, instead of to the JSP page. Change your forward to
reference the JSP instead of the action, like this:
forward name=success path=/adduser.jsp/
and things should start working normally.

Re: infinite loop
:-(
i am sorry. you are right.
i had few reports with out html:form in them and
when i give .cm in forward they work fine.
so i was thinking that it would be the same for
forms also.
thanks much.

Re: infinite loop
yes, martin. it works fine.
i have few .jsp pages without forms means they display reports and they work
fine with .cm mapping, so, i was thinking it would be the same for forms
also.
thanks much,
rama.

Subject: Re: infinite loop
Are you using extension mapping, with the extension .cm? If so, then
your
infinite loop is happening because you are forwarding from the action
right
back to the same action, instead of to the JSP page. Change your forward
to
reference the JSP instead of the action, like this:
forward name=success path=/adduser.jsp/
and things should start working normally.

Subject: infinite loop
hi all,
In continuation to my post yesterday,
The following is my code. The flow is fine till Forwarding to Success
and then instead of displaying, it starts again from the begining.
If i remove the if condition in validate method then it displays the
form with errors which is fine.
am i doing something wrong
thanks,
rama.

hello all, i posted a question regarding the Stackoverflow error. but i got no help. thought i will explain my problem in more detail. i have an adduser.jsp which is invoked thru a href in a normal html page. this adduser.jsp displays a form. there is formbean and actionclass for this adduser.jsp and the mapping is fine. currently, after i am into this problem, the action class does nothing except mapping the form to AddUser and forwarding to adduser.jsp when i invoke this jsp, i get the following error... nulljava.lang.StackOverflowError at allaire.jrun.servlet.ForwardRequest.getParameterNames(../servlet/ForwardRequest.java:206) at allaire.jrun.servlet.ForwardRequest.getParameterNames(../servlet/ForwardRequest.java:206): : this runs for some 100 lines or so and then at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:734) at org.apache.struts.action.ActionServlet.processPopulate(ActionServlet.java:2050) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1552) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:490) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at allaire.jrun.servlet.JRunSE.service(../servlet/JRunSE.java:1416) at allaire.jrun.session.JRunSessionService.service(../session/JRunSessionService.java:1082) at allaire.jrun.servlet.JRunSE.runServlet(../servlet/JRunSE.java:1270) at allaire.jrun.servlet.JRunRequestDispatcher.forward(../servlet/JRunRequestDispatcher.java:89) at org.apache.struts.action.ActionServlet.processActionForward(ActionServlet.java:1747) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1584) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:490): : this runs for another 100 lines or so. i figured that the line in org.apache.struts.util.RequestUtils.java has the following line multipart.setServlet(servlet); multipart.setMapping((ActionMapping) request.getAttribute(Action.MAPPING_KEY)); request.removeAttribute(Action.MAPPING_KEY);**//this is the line i did a system.out for Action.MAPPING_KEY and it is having the correct mapping. if i give a forward to another .jsp page, it works fine. so i thought the error is in my .jsp and removed everything except for html and head tags. nope no use. can anyone help me or point me to a hint. thanks, rama.

Hello, I am using Struts 0.5 version (modified to that it can handle default action mappings) and am using Caucho Resin 1.2.1 as the web server. I have defined my Action Servlet Mapping as : !-- Action Servlet Mapping -- servlet-mapping servlet-nameaction/servlet-name url-pattern/cpf/*/url-pattern /servlet-mapping and my Action Mapping configuration file contains : action-mappings !-- Default User Action-- actionpath="/defaultPath" actionClass="com.hp.cpf.beans.UserRegistrationAction" formAttribute="defaultActionForm" unknown="true" formClass="com.hp.cpf.beans.UserRegistrationForm" forward name="success"path="/cpf/jsps/MainController.jsp"/ /action /action-mappings When I send a HTTP request, the ActionServlet forwards that to "/cpf/jsps/MainController.jsp" (as defined by the "forward" tag). Since, the forwarded URL starts with "cpf", it is again redirected to the ActionServlet which in turn forwards it to the "/cpf/jsps/MainController.jsp". This keeps on looping until I hit a "Too Many Servlets" exception. Any pointers on how to work around this problem. Thanks in advance, Swapnil.

In other words, you might arrange your web app files like this: WEB-INF/ web.xml struts-config.xml jsps/ ... *.jsp files ... and the path entry would be "/jsps/MainController.jsp" instead of "/cpf/jsps/MainController.jsp".

Re: Infinite Loop
That's a possibility. But there is a bunch of code and existing directory structure which i would rather not modify unless I have no other option. Thanks, Swapnil. - Original Message - From: Craig R.
