Error Handling
I have a question regarding error handling. There are many camps that advocate different error handling methodologies. What is the best way to do it when designing an application? t - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Error Handling without using errorPage directive
Hello all,
I'd like to handle any and all exceptions handled thrown by my JSP pages
declaratively, ideally using global-exceptions in struts-config.
Currently, I have a JSP page called by a tile that uses the JSTL Tag
Library. Using the c tag I perform a check like this:
c:if test=${!empty featuredProductView.title}
... do some work ...
/c:if
If the method getTitle() throws an exception, I currently see the
following on the screen:
-- snip --
javax.servlet.ServletException: javax.servlet.jsp.JspException: An error
occurred while evaluating custom action attribute test with value
${!empty featuredProductView.title}: An error occurred while getting
property title from an instance of class
com.mandaladesigns.apps.commerce.framework.view.FeaturedProductView
(com.mandaladesigns.common.exceptions.MandalaException)
-- snip --
This also appears in the tomcat localhost log along with the stack
trace. But what's really interesting to me is the data I placed in
com.mandaladesigns.common.exceptions.MandalaException, which is my own
exception type that subclasses RuntimeException. Though explicitly
using an errorPage directive in the page works, I'd like to avoid having
to place an errorPage directive in all of my JSP files.
So, is there a way that I can place a directive, either in web.xml or
struts-config.xml that will handle these exceptions? It seems that
using error-page in web.xml and global-exception in
struts-config.xml directives are not consulted for this situation. I've
created entries for every type of exception that seems relevant in both
places but they don't seem to be getting called.
Thanks for your help,
Jonathan.

RE: Struts Error Handling Problem
What do you mean if there is a reason for this? In the case of an error, you can output error msg through html:error/ In your case, you might want to try return back to your input instead of forwarding it to the .jsp page. I know they are almost the same, but they is a mirror difference. So here comes the harder part. If you believe that this is what's supposed to happen, then you found a bug. You can submit your bug through bugzilla.apache.org.

RE: Struts Error Handling Problem
I didn't finish the first paragraph!! Sorry. See [[append]] --- What do you mean if there is a reason for this? In the case of an error, you can output error msg through html:error/ [[append]] and all the data entered will be retained if you return to the original jsp page. --- Outlook is horrible for editing! But anyways, I guess what I wanted to emphasis was that you can display errors along with all the form data retained. -Original Message- From: Yansheng Lin [mailto:[EMAIL PROTECTED] Sent: July 30, 2003 3:10 PM To: 'Struts Users Mailing List' Subject: RE: Struts Error Handling Problem What do you mean if there is a reason for this?

Struts Error Handling Problem
I am currently experiencing a problem with the Struts error handling framework.
I am trying to use the error handling framework from ActionForm and
LookupDispatchAction classes.
The problem I have is in regards to display of error messages. I have found
that error messages are being displayed correctly using the html:errors/ tag
from a ActionForm validate method, but are not being displayed using the
LookupDispatchAction methods. Please see below:
ActionForm
public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest
httpServletRequest) {
ActionErrors errors = new ActionErrors();
errors.add(field, new ActionError(messageKey));
return errors;
}
LookupDispatchAction
public ActionForward next(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
...
ActionErrors errors = new ActionErrors();
errors.add(field, new ActionError(messageKey));
if(!errors.isEmpty()) {
saveErrors(request, errors);
}
return (ActionForward)mapping.findForward(target);
}
Could someone please tell me why this is so. I would be most interested if
anyone could provide a solution for this.
NOTE:
I am using the Struts version 1.1 release with tomcat version 4.1.24
Yours Sincerely
Rodney Paul

Hi, Can anyone send me a solution for the following problem: From two jsps, I am coming to the same action class. (in the first jsp, I have a link, clicking on this will go to an action say MyAction. From the second jsp also, I can goto the same action MyAction). In the MyAction class, how do I write code to return to the parent page when error occurs. (I am catching error using ActionErrors) action path = /MyAction type = mypackage.MyAction name = myFormBean scope = session forward name=success path=/pages/Result.jsp / /action Here, if the forward is success, i am able to got Result.jsp. But if any error is there, how do I display the error in the parent page? (I can come to this action from two different parent page) Please advise.

Re: error handling
Hi pramod, you once thoroughly take a look at actionerror and actionerrors docs. If u want to route ur errors to the parent page, give the following statement in your action class. actionErrors.add(ActionErrors.GLOBAL_ERROR, new ActionError(errors.tx.incomplete)); saveErrors(request, actionErrors); return (mapping.findForward(failure)); Than in struts-config.xml,Add the following line. forward name=failure path=/vascdt/StaticUpLoad.jsp / /action Than in your jsp type down the following html:errors / The above thing works for ActionErrors.GLOBAL_ERROR.If u want to handle individual errors u have to do minor modifications which any good struts tutorial can explain.Thats very simple.

AW: error handling
Hi Pramod, One solution would be to define two different action mapings as follows: action path = /MyActionFromMyFirstJsp type = mypackage.MyAction name = myFormBean scope = session input =/pages/myFirst.jsp forward name=success path=/pages/Result.jsp / /action action path = /MyActionFromMySecondJsp type = mypackage.MyAction name = myFormBean scope = session input =/pages/mySecond.jsp forward name=success path=/pages/Result.jsp / /action In your action you then use 'return mapping.getInputForward()' in case of error.

If you really cannot set multiples action-mappings in struts-config.xml (that is the
cleaner way to do), you can add a
parameter to your request for the incoming JSP :
html:hidden name=from value=/a.jsp/
and build a new forward in your action when errors occurs :
if (!errors.isEmpty()) {
saveErrors(request, errors);
String commingFrom = request.getParameter(from);
return new ActionForward(from);
}

Hi Pramod, did you add the 'input' attribute to your mapping? If yes, I don't know what's wrong with it. I assume that you are using struts 1.1, are you? The 'old' way to do it was 'return new ActionForward(mapping.getInput())', I think. May be you could try this as well.

Re: error handling
you will something in the session for this.
I modified the workflow stuff to handle this
situation.
If a mapping has more than one path to it -- then you
have to override default behaviour in order to get to
the calling mapping.
I am thinking now that it would have been easier to
specify a different mapping that handles the return
differently. This would force me to make sure my
back-end access is re-usable however.

Excellent catch :-) in fact I forgot to put the 'input' attribute. Now everything is working fine!!! Thanks you very much Robert!!!

If yes, I don't know what's wrong with it. I assume that you are using struts 1.1, are you? The 'old' way to do it was 'return new ActionForward(mapping.getInput())', I think. May be you could try this as well. Cheers Robert -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 27.

But, the mapping.getInputForward gives me an output like this: reached here...failure actionForward : ForwardConfig[name=null,path=null,redirect=false,contextRelati ve=false] But, by giving two mappings in the struts-config, I was able to solve the probelm for the time being. Instead of mapping.getInputForward, I am setting one more forward name? for each action mapping to handle the failure case. I don't understand why the mapping.getInputForward returns null.

error handling
Hi, being pretty new to Sturts, I just finished a simple form with the according FormBean and Action classes. Now I face the problem, that I should display the error Text if an entry is missing and change the style of the input field. html:errors property=.../ works fine for displaying the error message, but I was just wondering if there is a way to determine if there is an error set for the property. e.g. storing the errortext in a variable before displaying and changing the style of the field depending if the variable is empty or not. regards, Michael - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Error Handling Database constraints
I think the database constraints are anyway necessary unless your database is set up for table level locking or with isolation level serializable as it would be possible for another txn to insert the record after your first txn's select. Since these constraints exist in the database, the corresponding exceptions need to be caught and handled, I guess.

Re: Error handling (ServletException)
Your action throws an Exception which got rethrow as ServletException by the controller if the original exception is not caught by your handler. So you need to change your configuration to catch Exception ( or whatever the real one is) not ServletException.

about html:error ( error handling )
Hi there,
I'm trying to make an error handling in my web application with
logic:present and html:errors.
but I'm stuck.
what I wanna do is that
when struts catch the error (user didn't fill in the required textarea) ,
struts say there's an error.
And
even though there were no errors, strust says there was No error.
now I can do only former one with the code below...
In ApplicationResource.properties file --
username.required=FF (-- red color in html)
-
In ActionForm bean --
ActionErrors errors = new ActionErrors();
if(.){
errors.add(username, new ActionError(username.required));
}
-
In jsp --
logic:present name=%=Action.ERROR_KEY%
html:errors property=username
/logic:present
-
when struts catches the error, the HTML( transformed from jsp ) write
out FF.
I want struts write a word I specified even though There's NO error.
Is it impossible ???
why I wanna do this is that I wanna change the font's color depending on
either error or not.
If there's error font color=fffoobar/font
If there's NO error font color=fffoobar/font
I tried coding in jsp.
font color=
logic:present name=%=Action.ERROR_KEY%
html:errors property=username
/logic:present
logic:notPresent name=%=Action.ERROR_KEY%
F
/logic:notPresent
foobar/font
This does NOT work because if username property is okay , but other
properties got errors, html:errors property=username will be
processed...
so I gotta do like below...(since I don't know how to code, I just write
words)
font color=
logic:present name=%=Action.ERROR_KEY%
if(this error is username property's one){
html:errors property=username
}else{

}
/logic:present
logic:notPresent name=%=Action.ERROR_KEY%

RE: about html:error ( error handling )
hi wolfgang,
you do not have to go this way.
1. in the struts-config.xml add in your appropriate action the attribute
validate=true.
2. in your actionformbean there is (has to be ) a method called validate().
inside this method you only add your ActionsErrors object.
If there is not error you have to return null
else you have to return your ActionErrors object.
i work this way and it works on my system.
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if ((username == null) || (username.length() 1))
errors.add(username, new ActionError(login.error.username.required));
if ((password == null) || (password.length() 1))
errors.add(password, new ActionError(login.error.password.required));
if ((organization == null) || (organization.length() 1))
errors.add(organization, new
ActionError(login.error.organization.required));
if ((language == null) || (language.length() 1))
errors.add(language, new ActionError(login.error.language.required));
return errors;
}
hopefully i could help you

Re: [STRUTS] Form error handling
Kiuma, You can use one of the following: html:error/ tag: If placed at the top of a page, this will cause the errors to be displayed there. You should also ensure that errors.header and errors.footer messages are defined in your application resources file. This will help in the formatting of the resulting error messages. Something like: error.header=ul error.footer=/ul You could also use the validator tag which comes with the Struts Validation extension. It works similar except it acts as an iterator over all error messages. validator:errorsExist ul validator:errors id=error libean:write name=error//li /validator:errors /ul /validator:errorsExist There is a good write up on this provide by Ted Husted, Struts Tip #17.

URGENT!!! Dynamic parameters in App Resources for error handling
Hi all, I have been pretty happy using struts 1.0.2 for some time now. But now i have a problem. Please help. I know that we can user parameterized messages in the App Resources file for error messages. Depending on the no of parameters i can have an errors.add() method pass the parameters. But the problem is that i do not know in advance how many parameters i may need to pass? Any workaround guys? Also is there a way that i can access the message in App Resources File and modify it at runtime??? Pointers to a working code would be excellent.

For example, %@ taglib uri='/WEB-INF/struts-template.tld' prefix='template' % template:insert template='/main_template.jsp' template:put name='head' content='/templates/head.jsp' template:put name='content' content='/content.jsp' template:put name='footer' content='/templates/footer.jsp' template:insert/ When any exception is thrown in the content.jsp, the page will display with header only. I want to display the error_content.jsp if any eception is thrown in content.jsp is caught. Would anybody please share how you handle this, thanks!

Error handling philosophy in STRUTS
Hi, I am new to Struts and currently in the process of porting a JSP based Web Application to Struts and Velocity. Personally I hate stupid error messages like 'Failed to process your order' or 'Operation failed '. These type of messages are absolutely useless. For simple applications that simply store and retrieve data from a database it is possible do define possible error messages in advance and store them in a resource file. It is impossible in a distributed environment. When I look at samples and at the API I see that you offer ActionErrors and ActionError to process Errors. The real Error message is stored in a resource File and you pass a key to the ActionError class which then retrieves the message from the resource file. This is a nice feature in multi-language environments but in a distributed environment it is not possible know all possible error messages. I run a lot of CORBA stuff and have a lot of business logic implemented in various CORBA servers running on Windows and UNIX boxes. I have beans that wrap the CORBA clients and these beans are used in Action objects. There are many places where things can go wrong in a distributed application environment. I consequently use exeption handling and put all error messages in the exception itself. Since CORBA knows exceptions many exceptions are already defined on the IDL level. The server implementation (usually written in C++) fills human readable error messages in the exception object. Finally exactly these messages should be displayed on an end-users browser. I think the concept of displaying the error message on top of a form very good, since a user has a chance to correct the entries made if the error is caused by a typo. If there is a technical problem (such as a network beeing down, or a service such as a credit card validation or anything else on a remote location is not available) then I have at least a chance to return a meaningful error message. If I have to store messages in a resource file I could simply return something like Operation failed. This is not very usefull for either the end-user nor any support staff. I don't know what the philosophy of Error handling in struts is, but for distributed applications it would be nice if there would be a possibility to simply add a string to the ActionError object and then add it to the array of errors. Are there any reasons why this functionality is not available? A workaround is simple, I can put error messages in a request or session context and then display it in a velocity macro. But I think that this feature is something that would well suite for the framework.

Customised Error handling
The HTMLErrors tag handles validation errors well and of course I can load other text messages into an ActionError and present them via an HTML:errors tag. But I need to have at least one other category of error message. Is there a built-in mechanism for doing this or do I have to write my own tag? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: Customised Error handling
Hi, if you need special formatting for the errors: have a look at the validator error-tags. (in the nightly build or via ted's page hope this helps Alexander -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, November 19, 2001 12:04 PM To: [EMAIL PROTECTED] Subject: Customised Error handling The HTMLErrors tag handles validation errors well and of course I can load other text messages into an ActionError and present them via an HTML:errors tag.

Error handling with taglibs
Hi all My problem is, that I want to mark a textfield red and set the focus to it after I checked the fields in my from the ActionClass derived class and I detected an error in this input. I want to use taglibs also. Is there any possibility to do this in my from the ActionForm Class derived class, so that Struts will automatically set this field to another colour and set the focus to it ?If not whatis the best solution to mark theattribute in my from the ActionForm Class derived Class that this field isn't ok ? regards mike
RE: Error handling with taglibs
You need to hack in...and do some dirty work on each jsp page... You need to write your own html:error tag . Whenever there are some errors to be shown, you simply use some javascript to send focus to the first error field. Also in your jsp page (for evey text field) you might want to do something like an if,else condition.. If no error show plain, else show in red font with the error msg. Hope this helps. cheers, Amar.. -Original Message-From: Mike Prader [mailto:[EMAIL PROTECTED]]Sent: Friday, May 11, 2001 10:13 AMTo: [EMAIL PROTECTED]Subject: Error handling with taglibs Hi all My problem is, that I want to mark a textfield red and set the focus to it after I checked the fields in my from the ActionClass derived class and I detected an error in this input.

Re: Error handling with taglibs
I would suggest requesting a change to the current struts implementation. I think this has been thought about because there is the facility to include the property that has caused the error. I would also like to do something like this. I suppose there would be at least two ways of going about it: 1) Make the ActionErrors component more accessible in the jsp page - so that some kind of logic tag could be used to generate either a normal html:text tag or an html:text error tag, or 2) Add an error attribute to the html:text tag (and others) that would render the text box differently if an error is associated with it. These are my thoughts.

Search through the errors vector to see if it applies to the current property 2. Set background color to the text field to red or something like that. scott. --- Mike Prader [EMAIL PROTECTED] wrote: Hi all My problem is, that I want to mark a textfield red and set the focus to it after I checked the fields in my from the Action Class derived class and I detected an error in this input.
