The only download you need is the Struts binary distribution. If you read something that stated that you needed more than this, please let us know where you saw that, so that we can fix it. You don't need to download Ant at all unless you want to rebuild Struts, or the example apps that come with it. The binary distribution contains everything you need, already compiled and provided as one or more jar files, ready for you to include in your own application.See http://jakarta.apache.org/struts/installation.html#Installing for more information on using a binary distribution. The source distribution includes, ah, the source code and everything you would need to rebuild your own version of Struts. See http://jakarta.apache.org/struts/installation.html#Building if you want to do that. 2) Do I really have to download the Servlet API ?If yes, why? as weblogic supports servlets and why again to have one more servlet API? You need to have some Servlet API implementation available if you're going to compile your own code that relies on those interfaces. If WebLogic includes that (as I would assume that it does, but I'm not familiar with it), then you don't need to download another one. 3) In many installations it says, I need to put some *distribution files* or some *jar files* in WEB-INF directory. I don't find any such directory in weblogic5.1. So what to do? I suggest you follow the instructions for WebLogic 5.1. See http://jakarta.apache.org/struts/installation-wls.html for more information.

ResponseUtils.filter
Hi. The html:options tag handler (and other html tag handlers) uses ResponseUtils.filter to replace the characters '', '', '' and '='. This filter method changes the string 'Auml;ndern' to 'amp;Auml;ndern'. For english text this may be a nice feature, but it prevents developers to use text in languages with special characters (like german). Is there a workaround or can anyone rewrite the filter method so that it only replaces single '' characters and ignores character entities?

Re: recognizing a button
Hi.
If you want to figure out which button was pressed directly within your
ActionForm, try this.
Within the ActionForm that you associated with your HTML form, place the
following:
public void MyActionForm extends ActionForm {
protected boolean m_loadPressed = false;
protected boolean m_submitPressed = false;
...
public void setLoad(String load) {
m_loadPressed = true;
}
public boolean isLoadPressed() {
return m_loadPressed;
}
public void setSubmit(String submit) {
m_submitPressed = true;
}
public boolean isSubmitPressed() {
return m_submitPressed;
}
...
}
Now you can access which button was pressed by consulting the
corresponding methods within the ActionForm passed to the Action.perform
method.
Don't forget to reset the boolean values when you redisplay the form!

public void setSelection(int index, String[] value) { ... }

Re: Kick start to Struts
As Will says, there's more than one approach, but here's what works for me: 1. Write a specification, even if it's for yourself and just a paragraph long. I started a sample outline for one th example at http://husted.com/about/struts/example-spec.html , but never finished it. 2. Storyboard the application workflow. Here I just whip up some HTML screens with a visual editor like Dreamweaver or Frontpage. For testing forms, you can put another storyboard page in as the action target, and sample results on the other side. 3. Now that I know what I'm writing ;-), I design the model (database tables and queries). This is generally the first third of a project. 4. As Will says, identify, build, and test any reusable objects first, say for CRUD operations. Also try to layer your code so things like SQL commands and statements can be used and tested seperately. 5. Plan a path through your storyboard, and start building the JSP pages and the support code to hook them up to the objects and the model. Look for the simplest, useful workflow, and implement that first. This is generally the second third of a project. The last third is testing the application and making changes, including bug fixes. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 425-0252; Fax 716 223-2506. -- http://www.husted.com/about/struts/ William Jaynes wrote: Don't be too hard on yourself.

AW: recognizing a button
Hello Terence,
thanks for that, that's great.
Don't forget to reset the boolean values when you redisplay the form!
How do I do this the best way? Simply calling
form.reset(mapping, request)
in my action class doesn't work. I shouldn't call the setters directly,
right?

Hi.
If you want to figure out which button was pressed directly within your
ActionForm, try this.
Within the ActionForm that you associated with your HTML form, place the
following:
public void MyActionForm extends ActionForm {
protected boolean m_loadPressed = false;
protected boolean m_submitPressed = false;
...
public void setLoad(String load) {
m_loadPressed = true;
}
public boolean isLoadPressed() {
return m_loadPressed;
}
public void setSubmit(String submit) {
m_submitPressed = true;
}
public boolean isSubmitPressed() {
return m_submitPressed;
}
...
}
Now you can access which button was pressed by consulting the
corresponding methods within the ActionForm passed to the Action.perform
method.
Don't forget to reset the boolean values when you redisplay the form!

Re: AW: recognizing a button

Personally, I use two additional methods within the ActionForm:
public void setLoadPressed(boolean loadPressed) {

}
public void setSubmitPressed(boolean submitPressed) {
m_submitPressed = submitPressed;
}
which I call from the Action.perform method after having finished my

I discovered last night that the setter and getter must match precisely- not only the name must correspond with the property (obviously) but the object type of the property must be the same as well. i.e.: String getProperty() setProperty( String str ) can't be like this: String getProperty() setProperty( Timestamp t ) This seems a little odd to me. Does anyone know if this is mandated by the Servlet spec, or has WL just done something funky in their implementation?

Has anyone else seen this behavior before, or know what might be causing it? I have a Collection of beans I am trying to iterate through using the Struts iterate tag (works fine with WL5.1) but now I am getting an error that there is no getter method.

Re: Struts Tomcat 4.0
Sorry, Tom. I should have said, I now develop under Tomcat 4 on my own station, and then beta test the deployment on the remote server, which is usually either TC3 or Resin. This ensures that I am in compliance with the latest reference specifications, and not relying on legacy or proprietary behaviors. I share and reuse my core work, so compliance is important to me. Where I have gotten burned is designing around behaviour in one container, only to find it did not work that way elsewhere.

RE: Scalability
but I'm getting feedback from other developers that don't feel that Struts is a very scaleable framework. What exactly are they saying? I don't have any personal experience in this area but it seems to me that Struts is a rather thin layer on top of normal Java Servlets. All it really changes is that two pages (Model and View) are called instead of the usual one. The other features don't seem like the kind of things that would affect scaleability. So any criticism of Struts should probably be generalizable (if that's a word ;-) to Servlets if it's got any validity. Please send more details. Devon

RE: data beans and ActionForm
Hi Mike
To initialize attributes in your formbean you implement the reset method.
See below:
ActionForm someActFrm {
public void reset(ActionMapping mapping, HttpServletRequest request){
this.someBean = new SomeBean();
}
private SomeBean someBean = null;
public SomeBean getSomeBean () {
...
}
public void setSomeBean (SomeBean someBean) {
this.someBean = someBean;
}
public void setName(String someString) {
someBean.setName(someString);
}

The only thing I would add to your argument is the fact that Struts relies fairly heavily on Reflection to set attributes on beans.

All it really changes is that two pages (Model and View) are called instead of the usual one. The other features don't seem like the kind of things that would affect scaleability. So any criticism of Struts should probably be generalizable (if that's a word ;-) to Servlets if it's got any validity. Please send more details. Devon

RE: Scalability
On Thu, 9 Aug 2001, Kevin McLain wrote: The only thing I would add to your argument is the fact that Struts relies fairly heavily on Reflection to set attributes on beans. Since Reflection incurs a much higher overhead than a straight method call (although I have heard that JDK 1.4 improves this performance considerably) - I did a rough test and found that this could be as much as three times as long - it could become a scalability issue as well... Even if 3x is an accurate statistic (seems high based on my experience with JDK 1.3.1, especially when making repeated calls on the same bean class where the caching Struts does helps you out), the key question is, does it matter? If you run out of database access speed or network bandwidth first, for example, reflection that cost 100x the CPU of a direct call would still have zero effect on response time and the number of users you can support. Scalability requires knocking down (or working around) bottlenecks as you run into them. If this one happens to be the one you hit first, it's feasible to throw some more CPU at it (and trade the hardware cost for the developer cost of having to avoid the use of reflection). In most cases I've seen, though, CPU does not tend to be the gating resource. Craig

Re: Struts Tomcat 4.0
Keeping in mind that my day job is building Tomcat 4, I will add a few comments and answers below. On Wed, 8 Aug 2001, Ajay Chitre wrote: Hello, I have been playing with struts for the past couple of months and I have had fun playing with it. Time has come now to stop playing and get serious. I have been asked to develop a web app with Struts Tomcat. I have been using Weblogic for the past couple of years, but this is my first experience with Tomcat, so I need some help to take some decisions. (I realize that this email should really be sent to the Tomcat mailing list, but I believe there's enough expertise in this mailing list to get these questions answered!) After reading thru the Struts mailing list I have concluded the following. Can someone please tell me if I am on the right track? 1) From one of Craig's emails it sounds like I should be using Tomcat 4.0, not 3.2. Is that right? But Tomcat 4.0 is a beta release. Is it reliable? Tomcat 4 is beta only because the specs are not yet final -- that is a short term issue (all the J2EE specs will be going final together soon). The code itself is very solid for stand-alone use, which is the typical mode for application developers. The web connector code is less mature, but getting there fast. I use Struts + Tomcat 4 every day -- it's part of my unit test procedures on Tomcat 4 development that it *must* run Struts apps flawlessly :-). Note also that, while Tomcat 4 supports the new Servlet 2.3 and JSP 1.2 specs, it also runs Servlet 2.2 / JSP 1.1 based applications (which is the minimum platform for Struts) just fine. Backwards compatibility like this is a requirement in the 2.3/1.2 specs. 2) Doesn't look like Tomcat 4.0 supports EJB. Does it? No, and it won't. For developing web apps that use EJBs, you can use something like the J2EE RI (version 1.3 includes Tomcat 4 as it's web layer), JBoss (which integrates with Tomcat, although still 3.2 IIRC), or other similar environments. 3) If EJB is not available I can use JDBC - no problem - but doesn't look like I can create database connection pool in Tomcat. You've got three different ways to do connection pools in Tomcat 4: * As application-provided resources (i.e. the data-source declaration in struts-config.xml, using the connection pool already included in Struts. This works in Tomcat 4 just like it works in any other servlet container. * Using a third party connection pool implementation like Poolman (again just like any servlet container). * As JNDI-accessed resources (exactly as in the J2EE programming model). This is a little tricky to set up (due entirely to sketchy documentation) but is very useful when you plan to deploy on a J2EE environment (because they all support this feature). 4) From one of Ted's emails I think I should use Poolman to create database connection pool in Tomcat 4.0. Right? That's one option. Or you can use the one built in to Struts. Or you can use the JNDI-based support built in to Tomcat 4. 5) What's equivalent of Weblogic Time APIs? Tomcat workers, right? I assume this is for background job scheduling and stuff? You can deal with this in a variety of ways: * Add some code to Tomcat's internals (there are appropriate APIs and listeners to do this kind of thing) * Add a servlet-based job scheduler and run it as a web app (something like this is much more likely to be portable to other servers too). Nothing is provided for this out-of-the-box. 6) Can I set up Tomcat to send emails using Java Mail APIs? In Weblogic one has to make sure that mail.jar activation.jar is in Weblogic Classpath. Is there any special requirement such as this in Tomcat? The only requirement is that you make the necessary JARs available. In Tomcat there are (again) two options: * Include activation.jar and mail.jar in /WEB-INF/lib of your application (portable to *any* container) * Include these JAR files in $CATALINA_HOME/lib, which makes them available to all web applications. 7) Does Tomcat support JMS? You can certainly write web apps that use the JMS client APIs, in the same way that you can write mail clients that use JavaMail APIs. Tomcat is not a JMS server -- again, that is a J2EE app server level feature. 8) Which one is better - Log4J or LogKit (which is part of Avalon project from Jakarta)? I'm not going to touch that one :-). 9) What's the difference between 'Struts' 'Turbine' (which is another Jakarta project)? Pros Cons? Ted's pointer gives a pretty good summary. There's also a fairly even handed comparison on the Barracuda site at Lutris. That being said, people who like JSP, and J2EE-ish APIs, will tend to prefer Struts, while those who like Velocity/WebMacro, and don't necessarliy care about J2EE-ish APIs, will tend to like Turbine. I apologize for the length of this email. Thanks in advance for your time. - Ajay Craig

Wizard Form Authoring..
All, What is the best design practice that you have found for creating Wizard entry forms in the Struts framework? Thanks, Brian
Struts and Forte
Do any of you use Struts inside of FFJ 3.0 EE (EA)? Since the tomcat-apache.conf file gets created everytime you run FFJ's internal Tomcat, is it impossible to register the Handler for the .do actions coming from the client JSPs? Dan
Re: Construct context-relative URL in Javascript?

I want to do a POST and I want to be able to set the TARGET attribute for the FORM before posting as well. I want to set the form's ACTION attribute to that value. But I have multiple values that the form's ACTION attribute might get set to and so I have to do it in Javascript based on which button the user clicked on. The html:base looks like will calc the right absolute URL and I could create one for each button. But I'd have to make them invisible (since I don't want to the user clicking on them) and then have some way to get at their HREF attribute value. In theory that may be possible using DOM calls from Javascript if I set ID values for each A HREF element. But that's limit what browser versions could be used. So I'd rather have the values be placed in invisible controls by the server when it generates the page.

RE: JBuilder 5, Struts 1.0 WebLogic 6.0, a Tutorial
By the way, another good session I sat in on can be found at http://www.borland.com/conf2001/updates/, 3004, Building Extensible Web Frameworks Using XML, XSL-T, and Java by Richard Vowles. Trouble is, they put the wrong slide show into the archive. The code examples are correct and include Struts, Tapestry (Richard's favorite, I think), and xsltaglibs. Richard didn't seem to like Struts too much, but shows it anyway. He took a lot of time to show Tapestry. It's a replacement for JSP and my impression is that it uses Action Listeners better than any Servlet I've seen. But maybe I made that up because I was falling asleep during that part of the session...ala Homer Simpson (Cult Member: There's nothing like that in the movie. Homer: Yeah, I know.

RE: Retrieving property fields in Action Class
i've never done this myself, but just from looking at the API docs, it looks
like you can do something like the following from within your action class:
public class SomeAction extends Action
{
ServletContext ctx = servlet.getServletContext();
MessageResources msgResources =
(MessageResources)ctx.getAttribute(MESSAGES_KEY);
String someProperty = msgResources.getMessage(someKey);
...
}
MessageResources.getMessage() is overloaded about 10 or so times. the
method call above simply returns a message for the default locale. like i
said, i haven't tried this myself, but the docs suggest it will work this
way

Ted, thanks for the reply but I dont think that was quite what I was looking

Basically what I'm talking about it the ApplicationResources.properties
file. I know
you can retrieve these values through .jsp pages using bean:message

I would like to know if I can retrieve this same key value in an Action
class. If I can, can
someone show me how to do this.

Subject: Re: Retrieving property fields in Action Class
The best place to answer a question like this is the USER list, where
there are more people to help you. So I'll copy them in ;-)
But, yes, the ActionForm is passed to the perform() method of your
Action.
The Action also has access to a protected servlet property (or
getServlet() method), that gives it access to the public properties of

on JSP that you couldn't use in an Action.

Thanks for any input.

Hi all -
I am facing a weird problem, which I could not solve
in the last couple of hours. I checked up the
mail-archive but could not locate any solution to
this.
The application has a login screen (login.jsp),
which
validates a user. There is an ActionForm (LoginForm)
with appropriate get and set methods.
The struts-config.xml looks like :
form-beans
!-- Logon form bean --
form-bean name=loginForm
type=com.anshin.LoginForm/
/form-beans
!-- Process a user logon --
actionpath=/login
type=com.anshin.LoginAction
name=loginForm
validate=true
input=login.jsp
forward name=success
path=/login.jsp/
/action
When I execute the application (invoke login.jsp), I
get a 404 error on the page login.do. I gave
debugging statements and I find that the get methods
of the ActionForm gets executed, but nothing else
happens. It does not even enter the LoginAction
class.
But from the Tomcat startup messages, I find that
the
mappings have been identified and loaded by Tomcat.
I have struts.jar in WEB-INF/lib. I am really
banging
my head over this problem. The other applications
like
struts-example etc. are running fine ..
Pls. help.

If I have three tabs that are included at the top of each of the three body pages by a template, then what is the best way to make sure information is stored between requests for the different pages? Even though all three pages use the same ActionForm bean and Action class, I am running into the problem where the formbean is loosing its data (even though I check for submit in the reset() method). Is there a better approach than doing this? BTW, sorry about the multiple posts of some of my messages cluttering the newsgroup... our Lotus Notes server went nuts over here.

RE: newbie question
This is not related to the form. It looks like you may not have extension
mapping set up for your application. My guess is that if you type this in
your browser:
http://yourHost/pathToYourApp/login.do
you will also see a 404. That suggests that you need to add something like
this:
!-- Action Servlet Mapping --
servlet-mapping
servlet-nameaction/servlet-name
url-pattern*.do/url-pattern
/servlet-mapping
to your web.xml file. You might want to take a look at the web.xml file in
the struts-example app to make sure you've got everything else that you need.

Re: newbie question
Debasish, Everyone seems to be focusing on your action or extension mappings, but most of my 404s are caused by missing JSP files. What directory is your logon.jsp in? I keep my JSPs in a /jsp directory in the main application directory, so my forward would be: forward name=success path=/jsp/login.jsp/ I think that your forward would be incorrect unless you have your logon.jsp in the root application directory. Bill Debasish Ghosh wrote: Hi all - I am facing a weird problem, which I could not solve in the last couple of hours. I checked up the mail-archive but could not locate any solution to this. The application has a login screen (login.jsp), which validates a user. There is an ActionForm (LoginForm) with appropriate get and set methods. The struts-config.xml looks like : form-beans !-- Logon form bean -- form-bean name=loginForm type=com.anshin.LoginForm/ /form-beans !-- Process a user logon -- actionpath=/login type=com.anshin.LoginAction name=loginForm validate=true input=login.jsp forward name=success path=/login.jsp/ /action When I execute the application (invoke login.jsp), I get a 404 error on the page login.do. I gave debugging statements and I find that the get methods of the ActionForm gets executed, but nothing else happens. It does not even enter the LoginAction class. But from the Tomcat startup messages, I find that the mappings have been identified and loaded by Tomcat. I have struts.jar in WEB-INF/lib. I am really banging my head over this problem.

Iterate with offset=parameter
I am trying to iterate over a Vector using the logic:iterate tag. Everything works fine until I try to set an offset. The offset for where I need to start iterating from is passed in as a parameter to the page and I retrieve it using bean:parameter id=fromRecord name=FROMRECORD value=0/ when I try to use fromRecord in the iterate tag logic:iterate id=result name=search scope=session indexId=resultsPrinted offset=fromRecord length=20 I get the following on the page javax.servlet.ServletException: java.lang.String This makes sense since fromRecord is of type String and offset is expecting an int or Integer. So I then tried to make the offset a variable using % int fromRec = Integer.parseInt(fromRecord); % and logic:iterate id=result name=search scope=session indexId=resultsPrinted offset=fromRec length=20 This doesn't throw an error but doesn't set the correct offset and is always starting from 0. How can I retrieve the parameter and use it in the iterator? Kimberly MacKellar Thomson Financial Publishing [EMAIL PROTECTED]

Re: Kick start to Struts
I'd like to second much of what Ted said. I've just completed my first project using struts - I was building and learning at the same time. I had a series of about 10 screens, with some reasonably complicated jumping backwards and forwards between screens. This is how I ended up doing things: 1. Did a basic specification myself - it was to be a re-implementation of a current system so I had some idea of overall functionality. I had a fair idea of what was needed on each screen from the old system so this took the place of the storyboard. Part of this specification was the database design. 2. Developed the overall skeleton of page control and data entry, in combination with some simple JSPs ie no flashy graphics, fancy tables, etc just the fields and buttons I needed and some simple descriptive text. Then it got messy - we had the usual scope change and suddenly I had one of our designers writing a detailed specification (including defining what went on each screen and the validation), taking into account a raft of new functionality, while I got on with fleshing out the skeleton already constructed (as the deadline was tight and we couldn't wait). This is where you work really closely together - I was showing her my screens and the flow as I was going and we were discussing how we could best way implement the new functionality. The good side of this was that I could give her feedback on what would be easy to implement and what would be harder, so she wrote the specification to suit what would be easier (when possible). I finished the bulk of the processing (excluding certain back end pieces and particular chunks of functionality) to the point where our html expert could work on the jsp files. There were hooks in place for particular processing components I hadn't completed and the values on the screens were returning 0 or other dummy values. Funnily enough, this was about a week after the spec was finished grin. 3. Our html person took over making the pages look the way the designers wanted - with the ads and the fancy layout and fonts, etc. The stuff that would drive me crazy. After that it was co-development - I was plugging in back end functionality as it was completed and writing new bits and pieces in the webforms to make life easier for our html person. As you build the jsps and show them to people, you start finding out all the little requirements/difference in concept that you have between people. So I was making bug fixes, adding new tags, changing validation, and working on back end tasks like data conversion from old systems, operational instructions, etc. What would I do differently from what I did? 4. As Will says, identify, build, and test any reusable objects first, say for CRUD operations. Also try to layer your code so things like SQL commands and statements can be used and tested seperately. This is important - its not in my list above as I wasn't really doing it. Some larger bits of the overall system had been identified as shared/reusable components up front (like some of our database access code) and other people in the team were working on them. So I was just writing the hooks ready for the parts to be done, then plugging them in when they became available. I would have done more taglibs earlier - to make life easier for the html person. He inherited too many bits of Java in the JSP pages or I had to redo pages that were basically huge chunks of Java before passing this on to him - this due to my shortage of experience with JSP tags and taglibs when I started. Locking down the overall functionality before I started coding would have been nice, but then again so would a million dollars. Scope change is just life in the computer industry. While doing some of the back end work last meant that you had people looking at a functioning system earlier and able to spot misunderstandings in functionality. The downside is that you are trying to do front end bug fixes while implementing other functionality, and time can tend to get very tight fitting it all in. You need to have management who really does believe you when you say no its not finished as the following parts of the backend aren't finished/tested. To summarise I guess I'd say neither JSP nor Java comes first. Planning does. Work out your overall flow and functionality first, be it html screens or on paper, get a detailed specification written asap, and be prepared for lots and lots of iterations between the Java code and the JSP pages. And if the deadline is tight and you aren't a one man team, get ready for lots of talking to your fellow team members - even down to I'm going to be making the following changes to blah.jsp this morning while I implement blah. Is that okay or do you need the file to work on? Fiona
Re: New To Struts
Hi, I downloaded jakarta-struts-1.0.zip file and extracted the files in c:\jakarta-struts-1.0. But I think lib/commons-*.jar file is missing in my installation? Are those files important or can I do without them? The installation process still says I should copy the jars in WEB-INF directory. Where should I create this WEB-INF directory?

Let me explain u the doubts which I had going thru the page: 1) All the downloads had 2-3 versions (for example, ANT, it had binary release, source realease and some RPM), which one I have to download, do I have to download all the 3? btw, if u can explain me the difference between source release and binary release, as I see them in almost all the downloads. The only download you need is the Struts binary distribution. If you read something that stated that you needed more than this, please let us know where you saw that, so that we can fix it. You don't need to download Ant at all unless you want to rebuild Struts, or the example apps that come with it. The binary distribution contains everything you need, already compiled and provided as one or more jar files, ready for you to include in your own application.See http://jakarta.apache.org/struts/installation.html#Installing for more information on using a binary distribution. The source distribution includes, ah, the source code and everything you would need to rebuild your own version of Struts. See http://jakarta.apache.org/struts/installation.html#Building if you want to do that. 2) Do I really have to download the Servlet API ?If yes, why? as weblogic supports servlets and why again to have one more servlet API? You need to have some Servlet API implementation available if you're going to compile your own code that relies on those interfaces. If WebLogic includes that (as I would assume that it does, but I'm not familiar with it), then you don't need to download another one. 3) In many installations it says, I need to put some *distribution files* or some *jar files* in WEB-INF directory. I don't find any such directory in weblogic5.1. So what to do? I suggest you follow the instructions for WebLogic 5.1. See http://jakarta.apache.org/struts/installation-wls.html for more information. These are only few of the things. The more I read, the more I get confused? If you could clear my above queries, I can go ahead and then may be I will come up more questions?
