RE: Log4J and Struts - using Chiki's log4j configuration and getting tons of messages
Hi Matt
I can only assume that the initial error (when you have no log4j.properties file) is
down to the extensions you are using being dependant on log4j - which means you need
the properties file so it knows what to do.
Using the Chiki log4j sorts this out - but there are a couple of things which may be
giving you too much detail in your logs.
The category definitions only affect logging messages going thru that category, so
changing them in the properties file will only affect the messages which go thru that
category. Then there is the debug level as detailed in your web.xml
One question to consider is which category the messages are coming through (from one
of the extensions), and then include THAT category in your log4j properties file at
the appropriate level. You should find some mention of the Category in use in the
extensions documentation. By using the Chiki config for log4j, the used Category isnt
mentioned - isnt set to any level - so you're getting all the messages. By including
it and setting the level as required will reduce the number of messages.
I'd check your web.xml too. As the one included here doesn't have debug levels set to
zero...I'm not totally familiar with the extensions you are using (yet) but the
messages must be coming from them if you are not using any loggin in your app yet. So
check the docs that come with them (and examples) for any mention of the log4j
dependancy and configuration re the Category being used..
Hope this helps

Subject: Log4J and Struts - using Chiki's log4j configuration and getting tons of
messages
Hello,
I am trying to implement log4j in my application. I'm using the Struts nightly build.
If I don't have a log4j.properties file in my WEB-INF/classes directory, I get the
following error:
log4j:ERROR No appenders could be found for category (org.apache.commons.digester).
log4j:ERROR Please initialize the log4j system properly.
I think this is being kicked off my one of the servlets in my web.xml because I
haven't even written any code yet, but I am using Validator, Workflow and Tiles.
So I copied the log4j.cfg file from Chiki's WEB-INF directory, renamed and put in in
its place. Now I get more logging messages than I can stand, and I have changed all
the debug and detail values in web.xml to 0. My log file on startup is over 1000
lines long.
Does anyone have any idea how to configure this properly - or point me towards a
resource that does. A simple search the archives is fine as well.
Thanks,
Matt

Re: Editing a database record best practice?
Sadly, the web tier has special requirements for value objects that most (reasonable) value objects cannot meet. http://www.mail-archive.com/struts-user@jakarta.apache.org/msg19338.html http://www.mail-archive.com/struts-user@jakarta.apache.org/msg08070.html But ActionForms should not be passed up to the business tier, except like any other JavaBean that can be mined through reflection. The general approach is to transfer the data from the ActionForm into a standard value object, that could, for example, be used in a remote call. Of course, this is just for data collection. For data presentation, any old value object you already have should work just fine. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Java Web Development with Struts. -- Tel +1 585 737-3463. -- Web http://www.husted.com/struts/ Jonathan Gibbons wrote: OTT, as in amazing dull to code up yet another value object...

Re: App Design
ok, the link is rather old, and maybe also a bit dogmatic: But most of it still holds true. Apart from the usability-hassles described in the link, in my experience you can add a bunch of problems you get when you try to generate your frames programmatically (the simplest one being the requirement to generate a link to the preceding page(whatever that means when you use frames) that also had to work when javascript is deactivated - the history.back() at last works halfway consistent for almost all browsers, but it took them a while...) - then you have the problem with deep-links into the site (you almost always end up with an xml-file that contains the complete site-layout and from which you can generate right frameset - almost always buggy and hard to maintain...), synching data in different frames (using an equally bad mixture of javascript/sevlet-code...). There are some applications out there which almost all have to something with configuration (configuring a new car, a new pc and so on) which make heavy use of javascript and frames to maintain the state of the configuration: Although i agree that there almost always a whole lot of data flows from and to the browser, which can/should be cached in frames, in reality these configrurators almost always seem to be crashing short before purchasing your new car, which took you about an hour to configure... so, no, i don't see any real reason for using frames for other things than doing some static designer-portfolio-pages (but i think they are currently overusing flash for this purpose...) ps: excuse me for this elaborate rage, but i have been burnt before in projects where i was forced to use frames - Original Message - From: Keith [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Wednesday, February 13, 2002 10:25 AM Subject: Re: App Design Is there a good argument for using frames?

Basic Struts Question
Hi, My company is evaluating whether or not to introduce Struts into our application architecture as part of our next release, and I have a relatively simple/stupid question about how best to build the set of screens that we're using as part of our evaluation process. In this example, I have a screen that displays a list of users. The screen needs several request parameters to identify which list of users to display. From this page, the user can go to a separate worksheet to add an additional user to the collection, or modify an existing user, and when they successfully save the list page for the user collection they are modifying is redisplayed with the new data. The parameters for the list page need to be specified at run-time, since they are dependent on the selected list and the user logged in. For the list page, I have an action that uses the request parameters to get the list of data and add it to the request as an attribute so that the JSP can display the data. For the worksheet page, I've implemented a read action to get the data (in a modify scenario) and then forward to a worksheet page, and a save action to process the worksheet and save the data to the business tier. The confusion I'm having comes in when the save action successfully processes the request and needs to perform the forward to send the user back to the list page. The list page needs the list of users to be put into the request object for it. The list action looks for the additional data it needs to populate the list as request parameters, not as attributes, and Struts does not appear to auto-populate ActionForm beans from request attributes, just the parameters. So, which of the options below would appear to make the most sense when building a Struts based web app? - have the save action set the additional data as request attributes and have the success mapping forward to the get list action. The list action will just need to check if it's ActionForm object was populated from the request parameters, and if not, get the data it needs from the request attributes. - have the both the get list and save actions be capable of fetching the list data and populating it for the list screen, and have the save action's success mapping go directly to the list JSP. - build an ActionForward object to do a browser redirect using the struts-config.xml mapping to get the URI and then append additional parameters to the URI to get to the next page - store the information needed by the list page in the session and update it there as well as on the business tier (rather not do that since we already overuse the session to keep stuff around, and I was hoping to get the team to become better at keeping session usage down). Seems like the first option is the best, but I wanted to make sure I wasn't missing anything. Thanks for any help/advice. Robb Nedwick __ Do You Yahoo!? Send FREE Valentine eCards with Yahoo!

RE: Editing a database record best practice?
EJBs have their uses and sometimes are required (JMS, for example). Further, an EJB (especially a session bean) is no slower than any other Java entity accessing a database (which has more to do with network latency, and database performance than EJB technology) and provides great separation of the view from the model, plus, with the latest efficiencies in JVM and container technology there is no performance hit for using EJBs in and of themselves. All things being equal, performance, as has always been the case, is mainly determined by the code. Finally, where in the world did you get the idea that Sun has a hardware stake in promoting EJBs? That took a great leap of imagination! Cheers! Mark P.S. .Net is great technology. Do not let the typically fanatical pro-Java/anti-Microsoft bias blind you to the possibilities. Java 1.1 already runs in it, C# is a great combination of the best of C and Java 2.0, and someone is bound to develop a compatible Java 2.0 byte compiler for the framework within a year (rumor is IBM is already doing it). My guess is that .Net will encompass Unix as well in a fairly short period of time and the world of Net application development will be split between EJB and .Net developers.

I have to write export files to an another server.The code I am using is
not seams to be working fine .Some times it rewrites on an existing file.I am giving
my code sample here
access = ACCESS_WRITE;
long time = System.currentTimeMillis();
long timeSpawned = time;
// this routine tries 30 seconds
// to open a file, if not successful
while(!isOpen (((timeSpawned-time)/1000)30))
{
timeSpawned = System.currentTimeMillis();
try
{
out = new BufferedWriter(new FileWriter(filename,true));
isOpen = true;
}
catch(IOException e)
{
}
}
}
if(isOpen)
{
String line = ;
for(int i=0; iattributes.length; i++)
{
String att = person.getAttribute(attributes[i]);
if(att==null attributes[i].equals(PersonKeys.DATATYPE))
att = cha;
if(att==null)
att = ;
line += att + delimiter;
}
out.write(line);
out.newLine();
out.flush();
}
Is there is an another better way to do this?

Ye olde ApplicationResources.properties ant -- tomcat?
Hi All, on setting up my new struts app, I found that ant isn't copying my ApplicationResources.properties from my src directory into the build or the deploy directories. When I compiled struts from source, ant managed to sort the properties file out for the example app, but I can't see anywhere in the build.xml files where this is being specified. Does anybody know what I'm on about? I'm going to try to get around it by putting the properties file directly in the tomcat webapps dir where it should go, but I'd appreciate being able to handle it properly.

RE: Ye olde ApplicationResources.properties ant -- tomcat?
You need something like
!-- Copy associated resource files --
copy todir=${web.build}/WEB-INF/classes
fileset dir=${src.home} includes=**/*.properties/
/copy
This may be being done when you compile, but not otherwise, but without seeing the
build.xml
Hope this helps

Re: isTokenValid(request) is always returning false
Thanks for the reply Mark.
Well...that piece of code was just a test snippet. I have a problem in an Action -
TestAction (with action = checkData),
in TestAction.perform() the code which handles action=checkData I have
if (action.equals("checkData"))
{
saveToken(request);
//populate beans...etc
}
this populates a number of beans and these are used to display information in a jsp
page. This page
is just a confirmation screen for data which was entered in the previous screen. When
the user hits
the accept button on this page they go to TestAction(but with action=saveInDatabase).
In TestAction.perform()
for action=saveInDatabase I have
if ( action.equals("saveInDatabase") isTokenValid(request))
{
//save in database
resetToken(request);
}
but the trouble is I always have isTokenValid(request) evaluating to false, so this
part is always skipped
so the data is not saved in the database :(.
Cheers

Re: Basic Struts Question
I think you have the right idea with option 1. There's lots of old posts about this fiddly subject - it may take a while to dig for them. Try looking up workflow. I posted some of my code a while ago - no-one else seemed to think too much of it, but I still happily use it. if you search the archive:- http://www.mail-archive.com/struts-user%40jakarta.apache.org/ for ChainToPage, see messages under subject:- re: How to return to the page that called the action class?

I'm not proud of my code that does this but I'll mail it to you direct if you want a look. I think it would help (but be gentle). --- Robb Nedwick [EMAIL PROTECTED] wrote: Hi, My company is evaluating whether or not to introduce Struts into our application architecture as part of our next release, and I have a relatively simple/stupid question about how best to build the set of screens that we're using as part of our evaluation process. In this example, I have a screen that displays a list of users. The screen needs several request parameters to identify which list of users to display. From this page, the user can go to a separate worksheet to add an additional user to the collection, or modify an existing user, and when they successfully save the list page for the user collection they are modifying is redisplayed with the new data. The parameters for the list page need to be specified at run-time, since they are dependent on the selected list and the user logged in. For the list page, I have an action that uses the request parameters to get the list of data and add it to the request as an attribute so that the JSP can display the data. For the worksheet page, I've implemented a read action to get the data (in a modify scenario) and then forward to a worksheet page, and a save action to process the worksheet and save the data to the business tier. The confusion I'm having comes in when the save action successfully processes the request and needs to perform the forward to send the user back to the list page. The list page needs the list of users to be put into the request object for it. The list action looks for the additional data it needs to populate the list as request parameters, not as attributes, and Struts does not appear to auto-populate ActionForm beans from request attributes, just the parameters. So, which of the options below would appear to make the most sense when building a Struts based web app? - have the save action set the additional data as request attributes and have the success mapping forward to the get list action. The list action will just need to check if it's ActionForm object was populated from the request parameters, and if not, get the data it needs from the request attributes. - have the both the get list and save actions be capable of fetching the list data and populating it for the list screen, and have the save action's success mapping go directly to the list JSP. - build an ActionForward object to do a browser redirect using the struts-config.xml mapping to get the URI and then append additional parameters to the URI to get to the next page - store the information needed by the list page in the session and update it there as well as on the business tier (rather not do that since we already overuse the session to keep stuff around, and I was hoping to get the team to become better at keeping session usage down). Seems like the first option is the best, but I wanted to make sure I wasn't missing anything. Thanks for any help/advice. Robb Nedwick __ Do You Yahoo!? Send FREE Valentine eCards with Yahoo!

RE: [JBoss-user] How can I use a background process with JBoss
a message bean can be a good idea...
send an XML or text message to your message EJB,
which will process the request in it's own thread...
by the way, for long transactions, if you can avoid transactions
(by default they timeout in 30 seconds. you can change
that somewhere in the transaction config, but
anyway this is costly for the DB)
check the transaction mode used for the EJB...
using NotSupported for is interesting if their is no risk of
incoherence. note that such a non transactional bean
can call transactional EJB (Required TX mode for example).
each independent method call will be either Commit'ed or Rollback'ed...
If you don't have Message EJB, you can try to add a Thread'able object
in the Servlet context. I did it on Websphere
to scan mail...
then, either use the load-on-startup elemnt in web.xml
or explicitly start and stop...
as far as I understand servler context guaranty that
only one instance of the thread is used
you may also look about non HTTP servlet
which may respond to any protocol...
or even to soap clients...

rage on! I want java to survive .net. If people use too much technology or over eloborate designs, their systems get expensive to write hard to maintain then it looks like java is not good. When I see the posts by people using frames I am pleased I avoid them. One of my aims is to write systems that a beginner can read a junior can maintain. As for EJB's - oops I may start to rant! I write a business logic class to a standard design pattern, it can be called from a Swing app or a struts Action. If I want to call it from a remote server or it needs to participate in a distributed transaction it should take only a few hours to write a wrapper around it to make it an EJB session bean. It needs to receive/return it's parameters as value objects (to save repeated calls acoss the network). But like 98% of systems I have no such requirement - so no EJB's - for now. So what's the big deal about them - can't most of us can remain blissfully ignorant of them? Personally I'd like to see that b^%$ PetStore written in 3 ways - 1 - As a pet store would actually want it (Small scale architecture) 2 - Mid scale 3 - Monster scale.

There are some applications out there which almost all have to something with configuration (configuring a new car, a new pc and so on) which make heavy use of javascript and frames to maintain the state of the configuration: Although i agree that there almost always a whole lot of data flows from and to the browser, which can/should be cached in frames, in reality these configrurators almost always seem to be crashing short before purchasing your new car, which took you about an hour to configure... so, no, i don't see any real reason for using frames for other things than doing some static designer-portfolio-pages (but i think they are currently overusing flash for this purpose...) ps: excuse me for this elaborate rage, but i have been burnt before in projects where i was forced to use frames - Original Message - From: Keith [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Wednesday, February 13, 2002 10:25 AM Subject: Re: App Design Is there a good argument for using frames?

Re: How can I use a background process with JBoss
1 - Make the order process quick - it should be. Then you avoid the problem. Make user wait till it's done. 2 - Don't notify the user - let them do an enquiry to check if they want. If your system is any 100% reliable audited they will rely on it won't even want to be notified. 3 - Send the user an email when the order processing completes. As far as I know you can't interupt a web app from the server. 4 - Use a messaging system designed for asynchronous processing.

I read the list this morning and read 20 messages about too much traffic and then read 30+ messages that were either labelled OT (which I assume stands for off-topic) and messages like this, which are interesting but have absolutely nothing to do with Struts. This isn't a poolman, expresso, EJB list, this is a Struts list. Talking about the others where they deal with Struts is OK. If people think there is too much traffic on this list, they can stop discussing off-topic things. I bet the traffic would go down 25%. My 2 cents Jay On Wed, 13 Feb 2002, Keith wrote: rage on! I want java to survive .net. If people use too much technology or over eloborate designs, their systems get expensive to write hard to maintain then it looks like java is not good.

I write a business logic class to a standard design pattern, it can be called from a Swing app or a struts Action. If I want to call it from a remote server or it needs to participate in a distributed transaction it should take only a few hours to write a wrapper around it to make it an EJB session bean. It needs to receive/return it's parameters as value objects (to save repeated calls acoss the network). But like 98% of systems I have no such requirement - so no EJB's - for now.

There are some applications out there which almost all have to something with configuration (configuring a new car, a new pc and so on) which make heavy use of javascript and frames to maintain the state of the configuration: Although i agree that there almost always a whole lot of data flows from and to the browser, which can/should be cached in frames, in reality these configrurators almost always seem to be crashing short before purchasing your new car, which took you about an hour to configure... so, no, i don't see any real reason for using frames for other things than doing some static designer-portfolio-pages (but i think they are currently overusing flash for this purpose...) ps: excuse me for this elaborate rage, but i have been burnt before in projects where i was forced to use frames - Original Message - From: Keith [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Wednesday, February 13, 2002 10:25 AM Subject: Re: App Design Is there a good argument for using frames?

Well...that piece of code was just a test snippet. I have a problem in an

in TestAction.perform() the code which handles action=checkData I have

this populates a number of beans and these are used to display information in
a jsp page. This page
is just a confirmation screen for data which was entered in the previous
screen. When the user hits
the accept button on this page they go to TestAction(but with
action=saveInDatabase). In TestAction.perform()
for action=saveInDatabase I have

so this part is always skipped
so the data is not saved in the database :(.

problem with FormBean
Hi I am using form bean for the first time in struts . I wrote a simple form bean which sets and gets values. Also, I override the validate method in form bean with my logic. My action class does not do anything other than forwarding the control to some xyz jsp on success. So, now when I put in correct values for the text values(where validation succeeds and there is no error). It goes to the correct page i.e. xyz jsp. But when I do not put correct values in text boxes. It shows me HTTP 500 error. Can Any one tell me what I am doing wrong.

Subject: Ye olde ApplicationResources.properties ant -- tomcat?
Hi All,
on setting up my new struts app, I found that ant isn't
copying my ApplicationResources.properties from my src
directory into the build or the deploy directories.
When I compiled struts from source, ant managed to sort the
properties file out for the example app, but I can't see
anywhere in the build.xml files where this is being specified.
Does anybody know what I'm on about? I'm going to try to get
around it by putting the properties file directly in the
tomcat webapps dir where it should go, but I'd appreciate
being able to handle it properly.
Thanks

Re: error running tile: Cannot find message resources
There is two possibilities : * You have specified a message resource file in web.xml, but this file doesn't exist. (not the case if you use Tiles tutorial 'as is'). * You use a recent Struts version which require a resource file even if you don't specify it ;-( I have encountered this problem with latest nightly builds, and haven't dig in Struts yet to localize the problem (sound like a bug for me). I use a trick proposed by Hertzel Karbasi : define an empty resource file and specify it in your web.xml file.

Form Tags URL ... Goof-up!!!
Hi, I'm facing a lot of problems trying to maintain the extra path info in the URL. Few of these problems I've managed to work around by overriding methods in the base classes, specially ActionServlet class. The current problem that I have has to do with Form Tags. Lemme tell you the scenario to explain you the problem. I have a home page which has the login rm. Now I reach the home page using some URL like this http://myserver/servlet-name/extra-info/home. I'm using the form tag html:form to render the form. This unfortunately changes the form action to /servlet-name/login. And when the form is submitted this result in a URL as given below : http://myserver/servlet-name/login. As you would notice, the extra-info is gone. I dug into the FormTag code looks like this is the way it is supposed to behave (I can send you snippets of the code bcoz of which this behaviour occurs). Can anyone please tell me how to get around this problem. I think struts does a major amount of goof-up when it comes to extra path info it really amazes me to see how the designers of struts could have ignored such an obvious utility.

Re: HTML / Struts Help
You would do it the way you'd do it an any web application.
Here's how I do it: All my button field names start with btn. I would
name these buttons btnProcess, btnViewByOrg and btnViewByProcess (or
something similar).
In my perform method, I'd put code like this:
String button_pressed = null;
Enumeration e = request.getParameterNames();
while ( e.hasMoreElements() ) {
String param = (String)e.nextElement();
if ( param.startsWith(btn) ) {
button_pressed = param;
break;
}
}
At this point, button_pressed tells you the name of the button that was
pressed. I have a utility class that has this code in it and I use it
everywhere.

AW: HTML / Struts Help
if you want to user javascript do it like this,
import your buttons as image and use it as a hyperlink
a href=javascript:{document.forms[0].action='%=
request.getContextPath()%/do/admin/retrieveUser?username=%=
company.getUserForm(i).getUsername()
%criteria=%=companyData.getAccountName()%';document.forms[0].submit()}
Details/a
maybe it`s not the best solution, but you can now redirect to different
actions for different buttons,
you can change parameters in the url and so on

Hi.
I have a form that can be submitted by three different buttons, for example
the buttons read
(Button Labels)
Process
View by Org
View by Product
What I want to do is in the Action Class handling the submission, find out
which button was pressed, and act accordingly, whether it's an actionForward
(in the case of the view options) or kicking off another process (as will
be done by the process button)
So, how can I figure out what button was pressed in that Action class? Is
there a way to do that?

RE: HTML / Struts Help
you can set the property on the submit button and then use request.getParameter to get the value of the propery in your action. example : html:form action=someAction.do html:submit value=process property=toDo / html:submit value=view by org property=toDo / html:submit value=view by product property=toDo / /html:form In the perform method of your action you can then write : String s = request.getParameter(toDo); if ( s.equals(process)) process(); else if ( s.equals(view by org)) viewByOrg(); else if ( s.equals(view by product)) viewByProduct(); Greetings, Geert. -- Get your firstname@lastname email at http://Nameplanet.com/?su -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: HTML / Struts Help
This works, but then your users MUST have JavaScript enabled or your application will not work. We try to build applications that work if users have JavaScript or don't have JavaScript. It's just as easy to check this stuff on the server. In your application, maybe you have full control over the browser, but in most web applications, the developers don't have control over the browser, so depending on JavaScript might not be such a good thing. Just my opinion... On Wed, 13 Feb 2002, Thompson, Darryl wrote: Hello, When my JSPs contain multiple buttons that trigger different behaviour I use the DispatchAction...

Hi John
You can use the html:image tag and set the property to a value.
Then in the action, you are able to find out, which button was presed like this :
// find out if the create button was clicked
Enumeration enum = request.getParameterNames();
int clickedButton = 0;
for(int idx = 0; enum.hasMoreElements() clickedButton == 0; idx++) {
String paramName = (String)enum.nextElement();
if(paramName.startsWith(VALUE-OF-PROPERTY-NAME)) {
// what ever you want to do
}
}

RE: HTML / Struts Help - Summary
Jay
Thanks a lot. To summarize, here is my HTML
!-- HTML Snippet--
html:submit property=btnProcess
bean:message key=button.processSuspends /
/html:submit
html:submit property=btnViewOrg
bean:message key=button.viewOrg /
/html:submit
html:submit property=btnViewProd
bean:message key=button.viewProd /
/html:submit
!-- End of snippet--
and in my Action Class, I have the following
String button_pressed = null;
Enumeration e = request.getParameterNames();
while (e.hasMoreElements()) {
String param = (String) e.nextElement();
if (param.startsWith(btn)) {
button_pressed = param;
break;
}
}
Works like a champ
Thanks a lot.
the other thing I found out I could have done, was, based on the SAME HTML
SNIPPET I could have a property on the ActionFormClass called BtnProcess
(with getter and setter) and I could get its value as follows
// in the Action Form.perform()
ViewProcessSuspendsForm myForm=(ViewProcessSuspendsForm)form;
System.out.println(From the Action Form, getProcess(), the value is
+myForm.getBtnProcess());
// Note, the value I get from this corresponds to bean:message
key=button.processSuspends / from the HTML, which is the label on the
button loaded from the resource file. It happens to be Process Suspends. I
like the first solution better.
Anyway, thanks for all the responses and help.

You would do it the way you'd do it an any web application.
Here's how I do it: All my button field names start with btn. I would
name these buttons btnProcess, btnViewByOrg and btnViewByProcess (or
something similar).
In my perform method, I'd put code like this:
String button_pressed = null;
Enumeration e = request.getParameterNames();
while ( e.hasMoreElements() ) {
String param = (String)e.nextElement();
if ( param.startsWith(btn) ) {
button_pressed = param;
break;
}
}
At this point, button_pressed tells you the name of the button that was
pressed. I have a utility class that has this code in it and I use it
everywhere.

RE: HTML / Struts Help
I think the design of struts is that you should have get/setters in your form
beans for the button parameters rather than look at the request parms directly.
in form bean
boolean createButton;
public void setCreateButton(String createButtonParm) {
createButton = true;
}
public boolean isCreateButton() {
return createButton;
}
in form bean reset have
createButton = false;
==
Then in your action code you can test
if (formBean.isCreateButton())
==
hope that helps

I'm not sure if this is struts-kosher, but it works. I have a form that
includes two buttons:
html:submit property=submit value=Submit /
html:submit property=submit value=Forgot Password/
Then I added get/set methods for a submit property in the associated
FormBean. The Action class can then determine which button was pressed
by calling getSubmit and doing a string compare:
String submit = myform.getSubmit();
if ( submit.equals ( Forgot Password ) )
{
// etc...
}

RE: HTML / Struts Help - addendum to summary.
I like that solution.
I Think I'll alter my solution so that I'm doing it this way. Originally, I
was concerned about getting back Process Suspends or some other strange
string from
String getBtnProcess() ( a method on the ActionForm class) within the
Action.perform() method, but then I realized I have access to the message
resources, and that's where I'm getting that Process Suspends label
anyway, so why not just compare them.
I can therefore just do something like the following:
// Action.perform() snippet follows:
MessageResources application = actionServlet.getResources();
String thingToCompare =
application.getProperty(button.button.processSuspends);
I can then compare the results of getBtnProcess() with thingToCompare and do
whatever I need to do.
Good catch, thanks

RE: Reloading a page without refreshing Remote Scripting)
I did remote scripting in the ASP world. I haven't heard of it being used in the JSP world, but I haven't been around that long. Anyway, one time remote scipting is used is for dependent list boxes. For example after the user selects a country from one drop down list, the state/prov dropdown list is then populated w/ the appropriate data. An alternative to remote scripting in this case is to use JavaScript. All the data has to be pre-loaded into arrays, but then you can dynamicly populate dropdowns on the client side. Note too that remote scripting doesn't work w/ all browsers. I think we had to take the JavaScript approach w/ Mac browers. For an example, see http://www.cyclewacko.com. -Original Message- From: Rao, Sarveswara [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 13, 2002 10:14 AM To: 'Struts Users Mailing List' Subject: Reloading a page without refreshing Remote Scripting) Hi I have to developed a Page in which user enters the Zip Code and fields like City Name, State Name have to be populated without refreshing the page.

(NEWBIE question) problem with forms submitting with iterate tag
Hi all,
I have 2 forms, form 1 is search, form 2 is order.
Search has a searchAction. In this action the searh will be performed, and
the order bean will be populated and added to the order. The order page has
a logic:iterate tag which will loop over the list with results found, and
some input fields. This works fine.
If I find an error on the order field, I like to redisplay this page, but I
get the no collection found. My guess is that
the iterate tries to iterate over an empty bean, and thus creates the error.
Here's my code
SearchAction perform(...)
...
...
SearchForm searchForm = (SearchForm) form;
searchForm.performSearch();
OrderForm orderForm = new OrderForm();
orderForm.setSearchResults( searchForm.getSearchResults() );
request.setAttribute(orderForm, orderForm);
return mapping.findForward(order);
OrderForm validate() {
// something is empty
return errors
}
OrderAction perform(...)
...
...
...
}
How can I save the found searchResults?

RES: Want to check user is logged in every page server]
Hello Antony,
I extend the ActionServlet and Write some code to test if the
user is logged and if He has permission to acess a page.
It's very flexibile because is not only a test of login or not
login. I can test, for example, if user XYZ has permission to acess some
URL after He is logged in.

Assunto: AW: Want to check user is logged in every page server]
Hi
In the struts example the method used( as many people have pointed out)
to check that the person requesting the page is logged on is to have at
the top of each jsp a tag like
custom:checkLogonTag/
This tag should check to see if some sort of bean is present - this bean
indicates the user has logged on successfully - (method 1).
Do I need to do anything else or is this the safest way to ensure a user
is loged on before serving them the requested page.
Question, is there any point of having some sort of database record to
indicate a user has loggon on and checking with that database record as
well as the bean in (method 1) that the user is logged on?
Cheers
Tony
You can do this with a custom tag
custom:checkLogonTag/
of course you also need to implement this tag.
this is what actually does the job:
public int doEndTag() throws JspException {
// Is there a valid user logged on?
boolean valid = false;
HttpSession session = pageContext.getSession();
if ((session != null) (session.getAttribute(name) != null))
valid = true;
// Forward control based on the results
if (valid)
return (EVAL_PAGE);
else {
try {
pageContext.forward(page);
} catch (Exception e) {
throw new JspException(e.toString());
}
return (SKIP_PAGE);
}
}

Struts.

RE: Want to check user is logged in every page server]
Question about that solution:
isnt it so that the user will be checked ONLY when you try to submit a page?
Or does ActionServlet get activated as well when you request a jsp? I didnt
think this would happen, so the user credentials will only be checked if you
go to *.do.

HTML tags setting attribute to null?
Hi, I am seeing an unexpected result while using Struts 1.01/1.02 (upgraded and tested before I wrote this message.) My application uses two beans to populate some struts HTML tags (text, checkbox and select). The process flow is to call an action to create the beans and add them the session. The action then forwards to a JSP page. The user makes selections and submits the form data on the page. Then a second action processes the submission. When this second actions tries to access the two beans in the session, they are null. The attributes have not been deleted, because they can be seen with a call to getAttributeNames, but the objects associated with the names are null. A third session bean, which is not used to populate any tags, is still available, so whatever is populating the tags is replacing the beans with null. Is this a feature? If so, is there some way to disable it? Sid -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Passing Action Errors from one perform() method to another perform() method - Expert help?
Hi all. I'm trying to do the following. In an Action.perform() method, I'm adding an ActionErrors object to the request as follows // Snippet from an Action.perform() method ActionErrors errors = new ActionErrors (); errors.add(Processed, new ActionError(Processing Done)); saveErrors(request, errors); return new ActionForward(/suspends.do); // End of first perform() snippet Notice that I'm forwarding to a .do, which means I'm in another perform() method in the SECOND perform() method, I want to do some preprocessing (get stuff from a database) then forward to a JSP, and INLCUDE the actionErrors object from the first perform() method. Here's how I'm doing that now // snipped from second perform() method, mapped to suspends.do ActionErrors errors = new ActionErrors(); errors= (ActionErrors)request.getAttribute(Processed); saveErrors (request, errors); return new ActionForward(/invoicing/suspendsSummary.jsp); // End of second perform() snippet am I going about this in the wrong way? Is this even possible? basically, I want to pass a message back to the jsp that is really a status message (as in.. I'm done processing) thoughts?

RE: HTML / Struts Help - addendum to summary.
I am trying to do something similar, except with an HTML link.
I have a hidden form field:
html:hidden property=testHidden value=blah/
and then I try to set its value with an onclick function in my link:
html:link forward=testAction
onclick=javascript:document.getElementById('testHidden').value='Test';
Whenever I click the link, the testHidden field comes up as NULL. BUT,
when I use a regular submit button, it says the original blah.
Any ideas what I am doing wrong?

I like that solution.
I Think I'll alter my solution so that I'm doing it this way.
Originally, I
was concerned about getting back Process Suspends or some other
strange
string from
String getBtnProcess() ( a method on the ActionForm class) within the
Action.perform() method, but then I realized I have access to the
message
resources, and that's where I'm getting that Process Suspends label
anyway, so why not just compare them.
I can therefore just do something like the following:
// Action.perform() snippet follows:
MessageResources application = actionServlet.getResources();
String thingToCompare =
application.getProperty(button.button.processSuspends);
I can then compare the results of getBtnProcess() with thingToCompare
and do
whatever I need to do.
Good catch, thanks

I think the design of struts is that you should have get/setters in your
form
beans for the button parameters rather than look at the request parms
directly.
in form bean
boolean createButton;
public void setCreateButton(String createButtonParm) {
createButton = true;
}
public boolean isCreateButton() {
return createButton;
}
in form bean reset have
createButton = false;
==
Then in your action code you can test
if (formBean.isCreateButton())
==
hope that helps

Hi John
You can use the html:image tag and set the property to a value.
Then in the action, you are able to find out, which button was presed
like
this :
// find out if the create button was clicked
Enumeration enum = request.getParameterNames();
int clickedButton = 0;
for(int idx = 0; enum.hasMoreElements() clickedButton == 0; idx++) {
String paramName = (String)enum.nextElement();
if(paramName.startsWith(VALUE-OF-PROPERTY-NAME)) {
// what ever you want to do

Hi.
I have a form that can be submitted by three different buttons, for
example
the buttons read
(Button Labels)
Process
View by Org
View by Product
What I want to do is in the Action Class handling the submission, find
out
which button was pressed, and act accordingly, whether it's an
actionForward
(in the case of the view options) or kicking off another process (as
will
be done by the process button)
So, how can I figure out what button was pressed in that Action class?
Is
there a way to do that?

question re. accompanying Struts example
Hello everyone
I am going through the Struts example v 1.0.1, and I ran into a problem that
I am sure some of you have ran into or know the answer.
In the above mentioned app, there is a SaveRegistrationAction action class
with the following code I am interested in:
if (isCancelled(request)) {
if (servlet.getDebug() = 1)
servlet.log( Transaction ' + action + ' was cancelled);
if (mapping.getAttribute() != null)
session.removeAttribute(mapping.getAttribute());
session.removeAttribute(Constants.SUBSCRIPTION_KEY);
1 //return(mapping.findForward(test;
2 return (mapping.findForward(success));
This is the following behaviour I have:
1- in the Registration form, I press the Cancel button, which will run
through the above described code and the control goes to the logon.jsp page
instead of going to the one defined by success which is main.jsp.
question: how come?
2- if i comment the return (mapping.findForward(success)) line and
place return ( mapping.findForward(test)), it does go to the main.jsp
page but this is also not the right behaviour since the control should go to
the page defined in test which is a html file.
Any hints?
thanking in you advance guys

RE: HTML / Struts Help - addendum to summary.
Did you try using
Document.forms[0].testHidden.value instead? If that doesn't work, maybe you
could do it in a JavaScript function and then submit the form manually using
document.forms[0].submit (you'd have to make the submit button a regular
button that calls the method in the onclick)
You should be able to reference the .value of a hidden field from a
JavaScript function if nothing else.

SQL in Logic Bean or Action class
Just a simple design question. Having read through several posts and reading the Struts documentation. I was wondering what is the best design pattern regarding SQL placement. My thoughts were that I need to keep SQL out of the action class and pass all resultset data into Collections of beans. This helps keep from having tons of connections and resulsets sitting out there tieing up valuable database resources. The collection of databeans are then placed in a scope using the Controller(Action class)and made available to other logic processes in the scope and/or passed on to the view for data display. I am assuming this is because business logic beans should be designed and implemented so that they do not know they are being executed in a web application environment. Is my interpretation that SQL is part of the Model and should be placed in Logic beans tweaked? Or is this a 6 and half dozen scenario? Or is there another pattern that I am missing altogether?

You are on the right track. Keep the sql with the model. The only thing is don't let your collection of databeans make it to the jsp. That would then tie your presentation to the model. Very bad.

RE: SQL in Logic Bean or Action class
You are crossing the boundary in your action class when you put the result sets arraylist in the session. In the action class you should transfer that information into a different array list of view classes and put that in the session. I know it sounds like a lot of work and overhead to instance all those classes, but it is worth it and there is a helper class that might be of some use to you, I believe it is called like beanPopulate or something, maybe someone else can give you more info on that.

The parameter should be set to the page you posted from. bsr -Original Message- From: Dua, Amit [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 13, 2002 9:35 AM To: 'Struts Users Mailing List' Subject: problem with FormBean Hi I am using form bean for the first time in struts . I wrote a simple form bean which sets and gets values. Also, I override the validate method in form bean with my logic. My action class does not do anything other than forwarding the control to some xyz jsp on success. So, now when I put in correct values for the text values(where validation succeeds and there is no error). It goes to the correct page i.e. xyz jsp. But when I do not put correct values in text boxes. It shows me HTTP 500 error. Can Any one tell me what I am doing wrong.

Re: HTML tags setting attribute to null?
Please ignore this, it turned out to be a coding problem. Sid Stuart wrote: Hi, I am seeing an unexpected result while using Struts 1.01/1.02 (upgraded and tested before I wrote this message.) My application uses two beans to populate some struts HTML tags (text, checkbox and select). The process flow is to call an action to create the beans and add them the session. The action then forwards to a JSP page. The user makes selections and submits the form data on the page. Then a second action processes the submission. When this second actions tries to access the two beans in the session, they are null. The attributes have not been deleted, because they can be seen with a call to getAttributeNames, but the objects associated with the names are null. A third session bean, which is not used to populate any tags, is still available, so whatever is populating the tags is replacing the beans with null. Is this a feature? If so, is there some way to disable it?

Multiple struts-config.xml files?
I want to have multiple workflows, with users mapped to a particular workflow based on their role. I know that Struts doesn't support this now. Is there an intent to support this in the future? In the meantime, I'm interested in suggestions on the best way to implement this. Right now, I've done this: 1) I've created multiple ActionServlets, each of which reads it's own struts-config file. Each pair is the workflow for one role. 2) I've got a RoleDispatcherServlet that intercepts all Struts URLs, converts the URL to call the appropriate ActionServlet for the user's role, and forwards to that URL. Any additional suggestions or alternative methods are appreciated. Michael -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: Multiple struts-config.xml files?
I just had one ActionServlet, and for each action defined in it's struts-config.xml, there is a separate forward defined per role (prefixed by role name). role1_success role2_success etc. All forward name strings (e.g. success) get intercepted essentially by a super class Action and then the user's role is added to the forward name. The actual ActionForward is then looked up in the action mapping and returned to the Struts ActionServlet.

your properties file have to be written in Unicode encoding, not the native encoding, or else java will screw your characters up, since java can only deal with unicode Hertzel Karbasi - OPTinity eBusiness Solutions wrote: Hello All I have added the following to JSP files META http-equiv=Content-Type content=text/html, charset=UTF-8 %@ page contentType=text/html; charset=UTF-8 % html:html locale=true Change the locale in an Action to iw_IL And get: Constant strings inserted in JSP in Hebrew are OK.

Re: isTokenValid(request) is always returning false
saveToken() is in the action.equals("checkData") section of code, isTokenValid() is in
the
action.equals("saveInDatabase") section of code. The first time the user accesses
this action they hit the checkData section, which has the saveToken, they do not go
into the saveInDatabase section. The screen which is produced does not have any
form in it(is this a problem). The user hits the save button and the same
action.peform
method is called, only this time action=saveInDatabase
if (action.equals("saveInDatabase") isTokenValid(request) )
{
}
section is hopefully run. But it isn't since isTokenValid(request) is evaluating to
false even though in the previous time in this function called saveToken(request).
Why is the isTokenValid(request) evaluating to false even though I previously called
saveToken(request)
Thoughs/ideas anyone
Cheers

Thanks for the reply Mark.
Well...that piece of code was just a test snippet. I have a problem in an
Action - TestAction (with action = checkData),
in TestAction.perform() the code which handles action=checkData I have
if (action.equals("checkData"))
{
saveToken(request);
//populate beans...etc
}
this populates a number of beans and these are used to display information in
a jsp page. This page
is just a confirmation screen for data which was entered in the previous
screen. When the user hits
the accept button on this page they go to TestAction(but with
action=saveInDatabase). In TestAction.perform()
for action=saveInDatabase I have
if ( action.equals("saveInDatabase") isTokenValid(request))
{
//save in database
resetToken(request);
}
but the trouble is I always have isTokenValid(request) evaluating to false,
so this part is always skipped
so the data is not saved in the database :(.

A false parameter? :-)
Well, for starters, what are you passing into isTokenValid() and what is
the
method testing for?
I am passing into isTokenValid() "request" which is one of the
Action.perform() parameters.

What would cause
saveToken(request);
if ( isTokenValid(request)) {
System.out.println("isTokenValid(request) true");
}
else {
System.out.println("isTokenValid(request) false");
}
To always print "isTokenValid(request) false". I am always getting the
value of
isTokenValid(request) being equal to false.
