Re: javascript validation in struts
Hi Jonathan. A quick "dissection" of the code you posted might clarify some of your doubts.. onsubmit="return validateSigninForm(this)" * This piece of code calls a dynamically generated JavaScript function that's created when the page is rendered (for this to happen you have to include within the JSP containing the form.) As you can see, the function name is composed of three parts: "validate", which is a default value, + "Signin", which is the name of your form and the name specified in the tag, + "Form", which is another default value. action="signin" * This is just the Action name that's defined in struts-config.xml for this JSP an its associated Form bean. method="post"> * You also know what this is :^) The validating JavaScript functions containing the different kinds of validation for a given form are generated within the JSP code (although you can override this default behavior. See http://struts.apache.org/userGuide/struts-html.html#javascript). You should check the examples included in the Struts distribution to verify this (view source of JSP's after the browser renders'em). On every submit the JavaScript validation routines are called for every field participating in the validation process. Hope it helps...

This sounds like a set of indexed properties-- you'd need to keep the quantity 'lined up' with the item number, and you can't depend on the order of the parameters in the request.

Subject: RE: Proper n tiered exception handling
This worked for me for the most part. I now have a global exception and am
able to get the last trace within your comment tags. But in my data class I'm
closing my db connections and result sets in try catch blocks, so in this case,
the user would see the global error page in the following case if a connection
could not be closed for some reason which I know would be very rare, but still:
if (zDBConnection_m != null) {
try {
zDBConnection_m.closeConnection();
Logger.logDebug("Closed DB Connection in MyData.getRepByID
");
} catch (Exception zCONNEx)
{Logger.logMessage("EXCEPTION::MyData.getRepByID::Couldn't close CONN--"
+zCONNEx);}
}
This is not a fatal error and I don't want the user to see this. So my follow
up question is can I model a single exception to be thrown in my critical catch
blocks throughout all tiers of my app that can extend off a struts framework
class that shows the error to the user though a jsp page defined in
struts-config.xml
Im pretty sure im reading that you can, but am having trouble understanding the
theory. I'd LOVE an example of an ApplicationSpecificException class.

I'm sure your right Dan. That code is pretty old now and I would do it
differently today. But at the time given my understanding, this is what I came
up with. Actually couldn't tell you why I did it that way :)
The thing to focus on here in the example is the use of HTML comments to
"embed" the actually problem.

Why do you do all that work to print the stack trace?
Shouldn't exception.printStackTrace(out) do what you want?
This also follows the exception.getCause() chain and
prints out nested exceptions.
As a side note, if you really want to log
all nested exceptions then you have to do a little extra
work because some exceptions implement nesting in a way
that is not returned by getCause() (mostly because it
is an old implementation). I do the following:
log.error(exception.getMessage(), exception);
// struts utils often save original exception under
Globals.EXCEPTION_KEY
Throwable t = (Throwable) pageContext.
getAttribute(Globals.EXCEPTION_KEY,
PageContext.REQUEST_SCOPE);
if (t != null && t != exception && t != exception.getCause()) {
log.error("original exception: ", t);
}
if (exception instanceof JspException) {
Throwable t2 = ((JspException)exception).getRootCause();
if (t2 != null && t2 != t && t2 != exception && t2 !=
exception.getCause())
log.error("root cause: ", t2);
} else if (exception instanceof EJBException) {
Throwable t3 = ((EJBException)exception).getCausedByException();
if (t3 != null && t3 != t && t3 != exception && t3 !=
exception.getCause())

HttpSessionBindingListener only works on an attribute itself (so you
can tell when you get added or removd) -- it's been around since
Servlet 2.0. I was referring to HttpSessionListener (tells you about
session creations and deletions) and HttpSessionAttributeListener
(tells you about attribute add/remove/replace events).

RE: Proper n tiered exception handling
This worked for me for the most part. I now have a global exception and am
able to get the last trace within your comment tags. But in my data class I'm
closing my db connections and result sets in try catch blocks, so in this case,
the user would see the global error page in the following case if a connection
could not be closed for some reason which I know would be very rare, but still:
if (zDBConnection_m != null) {
try {
zDBConnection_m.closeConnection();
Logger.logDebug("Closed DB Connection in MyData.getRepByID
");
} catch (Exception zCONNEx)
{Logger.logMessage("EXCEPTION::MyData.getRepByID::Couldn't close CONN--"
+zCONNEx);}
}
This is not a fatal error and I don't want the user to see this. So my follow
up question is can I model a single exception to be thrown in my critical catch
blocks throughout all tiers of my app that can extend off a struts framework
class that shows the error to the user though a jsp page defined in
struts-config.xml
Im pretty sure im reading that you can, but am having trouble understanding the
theory. I'd LOVE an example of an ApplicationSpecificException class.
Thanks

I'm sure your right Dan. That code is pretty old now and I would do it
differently today. But at the time given my understanding, this is what I came

The thing to focus on here in the example is the use of HTML comments to

Why do you do all that work to print the stack trace?
Shouldn't exception.printStackTrace(out) do what you want?
This also follows the exception.getCause() chain and
prints out nested exceptions.
As a side note, if you really want to log
all nested exceptions then you have to do a little extra
work because some exceptions implement nesting in a way
that is not returned by getCause() (mostly because it
is an old implementation). I do the following:
log.error(exception.getMessage(), exception);
// struts utils often save original exception under
Globals.EXCEPTION_KEY
Throwable t = (Throwable) pageContext.
getAttribute(Globals.EXCEPTION_KEY,
PageContext.REQUEST_SCOPE);
if (t != null && t != exception && t != exception.getCause()) {
log.error("original exception: ", t);
}
if (exception instanceof JspException) {
Throwable t2 = ((JspException)exception).getRootCause();
if (t2 != null && t2 != t && t2 != exception && t2 !=
exception.getCause())
log.error("root cause: ", t2);
} else if (exception instanceof EJBException) {
Throwable t3 = ((EJBException)exception).getCausedByException();
if (t3 != null && t3 != t && t3 != exception && t3 !=
exception.getCause())
log.error("caused by: ", t3);
}

Struts does not do this for you, but your servlet container will set
the characteristics of the HttpServletRequest object to reflect the
paths of the JSP page. Thus, in a JSP,
<%= request.getServletPath() %>
should return you the name of the JSP, not the action to which the
form was submitted.

Re: Caching Appliction Level Data?
Caching or not is also a decision that you sometimes want to change after you see your application used in anger for a while. I like to provide a getter method on some application scoped bean that returns things like this, so I can change my decision to implement caching (or not), for any given set of data, without impacting the rest of the application -- it just calls the getter whenever it wants that data.

Re: Caching Appliction Level Data?
Without contesting the good points. I would say memory is cheap. For an application i worked on, we had about 6 different applications sitting on two 4 by 16 machines. The -xmx arguments of all apps put together came up to about 10 gigs RAM and the rest was left open. i dont think serious application owners care about money sunk on hardware. Further, I agree that caching requires an overhead in terms of keeping various clusters in synch or managing updates etc.. but clients can be kept transparent of all this. there may be a period of a few 100 milliseconds to upto a couple of seconds when clients may get dirty reads if the cache design allows it - but that could be a small price to pay over the general speed of cache access.

Problem validating form
I am fairly new to Struts and using the 1.1 version. I have a form bean that didn't have a validate method and just tried adding it (validate()) and now getting errors which I guess I kind-of understand but need to know how people generally work around this issue. The page has fields for title, author and some dropdowns for product and release. The page populates the product and release dropdowns from maps that I stuff in the request (request.setAttribute()). I added code in the validate to ensure that a title and author have been entered. Problem is: if you don't enter those, then my action never gets called to populate those items (product & release) in the request. Which later results in a jsp page error because it can't find the 'bean' for product (or release). Is this a problem that is generally 'caught' in the jsp page by checking for the bean or is there something that I need to do in the code? Is this where the reset() method might be used to provide a 'default' value? Mike Miller JDA Software Group, Inc. 7501 Ester's Blvd, Suite 100 Irving, Texas 75063

RE: Proper n tiered exception handling
I think you are missing out on some usefull features by using this. You
can't use the ActionMapping Parameter property to distinguish operations
and you will have to reimplement a
solution if you use DispatchAction. I think there are benefits to
declaritive exception handling, flexibility.

Hi.
My personal opinion is, that the Struts Exception handling doesn't bring any
benefits.
I use an approch based on inheritance and the "Template Method"-Pattern from
the GoF:
I create an abstract Class extended from "Action". All application-Specific
Actions extend that class. The Abstract Action-class is responsible for
catching all Exceptions that were not explicitly catched by the extending
class.
Source-Snippet from the Abstact Class "AbstractContoller.java":
public abstract class AbstractController extends Action {
//Template-Method. Calls "doExecute" on each Request and handles
uncaught Exceptions:
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
try {
return doExecute(mapping,form, request,response);
} catch (Throwable e) {
request.setAttribute("messagekey","error.unknownError");
log.error("Uncought Exception",e);
return mapping.findForward("error");
}
}
//All extending classed implement this method
public abstract ActionForward doExecute(ActionMapping mapping, ActionForm

Subject: RE: Proper n tiered exception handling
Why do you do all that work to print the stack trace?
Shouldn't exception.printStackTrace(out) do what you want?
This also follows the exception.getCause() chain and
prints out nested exceptions.
As a side note, if you really want to log
all nested exceptions then you have to do a little extra
work because some exceptions implement nesting in a way
that is not returned by getCause() (mostly because it
is an old implementation). I do the following:
log.error(exception.getMessage(), exception);
// struts utils often save original exception under
Globals.EXCEPTION_KEY
Throwable t = (Throwable) pageContext.
getAttribute(Globals.EXCEPTION_KEY,
PageContext.REQUEST_SCOPE);
if (t != null && t != exception && t != exception.getCause()) {
log.error("original exception: ", t);
}
if (exception instanceof JspException) {
Throwable t2 = ((JspException)exception).getRootCause();
if (t2 != null && t2 != t && t2 != exception && t2 !=
exception.getCause())
log.error("root cause: ", t2);
} else if (exception instanceof EJBException) {
Throwable t3 = ((EJBException)exception).getCausedByException();
if (t3 != null && t3 != t && t3 != exception && t3 !=
exception.getCause())
log.error("caused by: ", t3);
}

that is odd.
make sure your tag definition is pointing to the EL tld, you may have
updated the tag handle but not the tld reference?

Re: Proper n tiered exception handling
Different applications have different requirements. Take a look at the
exception handling in the workeffort application download
http://www.logicden.com to get an idea.
The files you may want to look at are: ApplicationExceptionHandler.java, files
in package com.logicden.workeffort.service.exception, struts-config.xml,
sql-error-codes.xml. Note that the application uses Spring and the SQL
exceptions get translated to custom exceptions using the mappings in
sql-error-codes.xml. This allows me to support multiple databases and keep with
the layers of the application agnostic of the target database.
The actions generally don't have any try/catch blocks. I let struts handle the
exceptions.

RE: Proper n tiered exception handling
I probably have not shown you enough in terms of setup. There is more to
configure this completely. I will try to outline this shortly. To answer your
question , I don't rethrow anything. It's not necessary. Your struts actions
have the following signature:
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest req, HttpServletResponse resp)
throws Exception
{
...
}
Any exception thrown within this method with propagate up through the exception
handling framework. Whether it's a SQLException, RemoteException or any
checked or runtime exception will flow upward. You delcare where to forward to
(what page). I designed a generic error handling jsp, because I did not want
to design a separate JSP for every type of exception. This is a preference
thing. My way was right for me. Here is my JSP for handling errors:
<[EMAIL PROTECTED] import="java.util.*" %>
<[EMAIL PROTECTED] uri="/WEB-INF/taglibs-log.tld" prefix="log" %>
<[EMAIL PROTECTED] uri="/WEB-INF/fmt.tld" prefix="fmt" %>
<[EMAIL PROTECTED] uri="/WEB-INF/c.tld" prefix="c" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%
Throwable t =
(Throwable)request.getAttribute("org.apache.struts.action.EXCEPTION");
if ( t!= null)
{
StackTraceElement [] trace = t.getStackTrace();
int size = trace.length;
out.print("");
}
%>
System Error
There's more to this story. Notice the line:
This is where I supply a customer message. The message is externalized in a
properties file for I18N. This is my syserror.jsp page which is referenced in
the struts.xml config.

I use declaritive exception handling which is built into Struts. Works great
for me. I really don't use custom exceptions that much any more because it's

try/catch blocks unless it's absolutely necessary. I allow all exceptions to

Here is an example of declaritive exception handling in the struts config:
When these exception types are thrown, the user is forwarded to the proper

view the exception stack trace by selecting view/source from you browser. Only

Thanks -- your option (2) seems to be working fairly well for me now. I still
have to see if struts will accept the faked up input tag and stick the data
into the form bean, but I don't see any reason why that shouldn't work.
I wonder why (1) wouldn't work for me though -- it gave me the same result as
the JSTL tag did. (It iterated fine but would just print out ${cur.prdNumber}

It seems odd that the EL tag does everything except actually do the

Re: Caching Appliction Level Data?

We do have a few caches in our >> application and are facing issues due to this design or an improperly >> implemented version of this design. Also, be aware that caching can actually degrade application performance in some cases. Everything you cache takes space in the JVM heap, reducing what's left to process active requests. So it's possible to lose more cycles in GC than you saved by caching in the first place. You can just keep increasing -Xmx, but that can hurt you if the JVM starts using swap space/virtual memory for the Java heap. If you're using a clustered cache, you also have the overhead of keeping the caches on each JVM in sync. That adds network as well as processing overhead for marshalling and unmarshalling cached objects. In summary, J2EE webapp performance involves a lot of tradeoffs. Caching is important but has to be used judiciously to be beneficial. -- Bill -- Bill Schneider Chief Architect Vecna Technologies 5004 Lehigh Rd., Suite B College Park, MD 20740 [EMAIL PROTECTED] t: 301-864-7253 x1140 f: 301-699-3180 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Validator, Indexed Properties and error messages.
Hello all, In review various documentation and several google search's I have found how to use the validator framework to validate indexed properties. In looking at the javadocs for the validator framework I see that the field class has an attribute called 'property' which (I think) tells the validator what property to associate any error message encountered during validation. My question is how do we associate the indexed properties error messages with different properties in the errors queue? For instance, if I have an indexed property that represents a list of items is there anyway to associate any error message for item 1 in the list using the property field. I want something like itemX as the property when the ActionMessage is placed into the queue as the property where the X represents the index of the item that the error happened on?

2) simply don't use the tag

Proper n tiered exception handling
I'm looking to get a handle on best exception handling practices in my app.
Kinda beginner question i guess, sorry.
Im catching the various sql and naming exceptions in the data classes and
logging and throwing a custom exception called ApplicationException which is
blank and provided below. I've read up but an still a little confused on how
exactly to build this exception class to extend the available struts exception
classes that would gracefully map to an error display jsp where i could display
the error to the user. Right now I just get the HTTP status 500 strack trace
on the screen.
Controller snippet that catches the data obj's thrown ApplicationException:
try {
zRepBeanBn =
MyData.getRepByID(StringUtils.convertToInt(request.getParameter("RepID")));
}catch (ApplicationException zAppEx){
throw zAppEx;
}
ApplicationException that needs work: How do I extend this?
public class ApplicationException extends Exception {
public ApplicationException(String message) { }
}
Thanks

Re: MESSAGES_KEY not found in request
I finally found them. After going through some struts sources. The messages are stored under: session.getServletContext().getAttribute(Action.MESSAGES_KEY) I was mislead by some examples in the web where you are told to fetch them via: request.getAttribute(Action.MESSAGES_KEY); Best regards René Thol René Thol schrieb: Hello again, since I'm stuck to struts1.0.2 and there's no way to disable filtering when using bean:message I'm trying to access MessageResources directly within my JSPs. But there is no entry regarding the Action.MESSAGES_KEY. Neither within the request nor within the session. I'm going through all request parameters and attributes within my Action's perform method after calling super.perform(...). No entry is found! So my question is: How does bean:message find the entries if they are not set according to the documentation!?

Antwort: bean:include
Hi! Why not just use jsp:include. There's nothing wrong with it. You can even use a request attribute for setting the jsp page.
