Question of using Struts for the J2EE pattern

I am now using Struts for the development. I have 3 questions about J2EE
pattern by the use of Struts:
1) How can I use Struts to create the Front Controller? In the book
descibing Front Controller, it is a servlet file which receives the request
and then dispatches to the appropriate view according to the request.
However, in using Struts, should I use the same way? However, I found that
in using Struts, I can call the controller class which subclass
ActionServlet, all the views forwarded are declared in the
struts-config.xml. Am I right in this method?
2) In the project, there is a Front Controller which dispatches the request
to the appropriate view (jsp file). Of course, I use Struts to do this.
However, I expect that the user is impossible for going to the view (jsp
page) directly by typing the address of the jsp file. I hope that the user
can go to the view through the controller only. How can I do this?
3) There is a problem by using browser - when a user browses a site, he can
press the 'back' button to the previous page, and then click the 'forward'
button also. How can I prevent this by using Struts? I found that in some
sites, when the user clicks the 'back' button, an error page displays. How
can I do this? Thanks!
Many Thanks!
Stephen

I'll take a stab at number 2 and number 3.......
2) You could have the controller object place a "flag" in the request that is dispatched to the JSP. Make the JSP check for that flag to ensure that this request came from the controller object. If the request comes from anywhere other than the controlle object, you can display an error page, or you could redirect them back to the controller. You could also use the HTTPSessionObject to place flags for users and have the JSP check there.
3) Keep a log of the user's activities in the HTTPSession. Whenever a page is invoked, have it check to see if the user has already been here, and if it is appropriate for the user to be here again.
Hope this helps!!

Using Struts or Spring dilemma?

HI all,
just a query , if we want to create a huge application having around 100's of Enterprise Beans and JSP pages around 1000, which Framework one should choose or go for between Struts and Spring. I have worked on Struts it seems to be popular choice and stable. But don't even have a vague notion about Spring Framework.
Wherein the application demands stability and performance enhancement.
Avadhoot.

Struts and Spring are two seperate frameworks , one can be used to implement View lyer using MVC and the other can contain all aspect of your application from the view to business and back end connection.
you can use Struts with spring , int this scenario struts will be the View layer and spring framework will handle other stuff like DA , Mailing , Transaction , Secrity ,....
I can say that :
go with EJB for Business layer , Use struts for View
and use netbeans 5 as IDE , it made developing ejb stuff too easy.

Using CSS for Struts JSP presentation using tiles

hi all,
i want to use CSS instead of table TRs ,TDs,TABLE in my jsps.
can anyone help me how can i achieve that?
i want to use css with struts presentation using tiles
i couldn't find much information about using CSS for jsps on the web can anyone guide me with proper information in this regard?
regards and thanks in advance

Actually, I just realized it's the exact same syntax as regular html (which I was thinking, but for some reason it didn't work the night I posted):
<head>
<link rel="stylesheet" href="yourstylesheet.css"/>
</head>I'm not sure why it didn't work for me the first time.

Approaches for Prepopulating dropdowns in Jsp using struts.

Hi,
I'm having a functionality working of pre-populating dropdowns using struts like:
ArrayList list = getRoles(); //This method will return list of roles
request.setAttribute("roles", list);
By setting this collection in the request it will be availbel to <html:select and <html:options> tags for pre-populating. My question here is do we need to set the list (that is to be displayed in the JSP) in request scope deliberately, or there are other better approaches as well to do the same, like using expression language and accessing the method directly.
Thanks,
Prashant.

Why dont you use ActionForm.
declare a private variable
//variable
private List roles=null;
//methods
public List getRoles();
public void setRoles(List roles);and in ActionClass
ArrayList list = getRoles(); //This method will return list of roles
form.setRoles(list);This collection object will be available in the jsp forwarded from that action in the scope specified in the struts-config.
then use
<html:select>
<html:options collection="roles" labelProperty="name" property="id" />
</html:select>

How can I get the context-parm from a web.xml file using struts?

Hello:
I need get the context-param from the web.xml file of my web project using struts. I want configurate the jdbc datasource connection pooling here. For example:
<context-param>
<param-name>datasource</param-name>
<param-value>jdbc/formacion</param-value>
<description>Jdbc datasource</description>
</context-param>
and then from any Action class get this parameter.
Similar using a simple server can be:
/** Initiates new XServlet */
public void init(ServletConfig config) throws ServletException {
          for (Enumeration e = config.getInitParameterNames(); e.hasMoreElements();) {
               System.out.println(e.nextElement());
          super.init(config);
          String str = config.getInitParameter("datasource");
          System.out.println(str);
     public void doPost(HttpServletRequest req, HttpServletResponse res)
          throws ServletException, IOException {
          // res.setContentType( );
          System.out.println("Got post request in XServlet");
          PrintWriter out = res.getWriter();
          out.println("nada");
          out.flush();
          out.close();
but only this works for init-params, if I use
<servlet>
     <servlet-name>MyServlet</servlet-name>
     <display-name>MyServlet</display-name>
     <servlet-class>myExamples.servlet.MyServlet</servlet-class>
     <init-param>
     <param-name>datasource</param-name>
     <param-value>jdbc/formacion</param-value>
</init-param>
</servlet>
inside my web.xml. I need something similar, but using struts inside the action class for that I can get the context-params and call my database.
Thank you

To get context parameters from your web.xml file you can simply get the ActionServlet object from an implementing action object class. In the perform (or execute) method make the following call.
ServletContext context = getServlet().getServletContext();
String tempContextVar =
context.getInitParameter("<your context param >");

How to assign bean value to a local variable in JSP using struts.

Hi everybody!
I've a problem that puzzled me on how to assign a bean value to a local variable like String in JSP using struts.
we can have someting like this to display the value
<bean:write name="detailService" property="status" />or
<bean:define id="theStatus" name="detailService" property="status"/>
This is country: <%=theStatus%>but an error occured when I tried like this:
String currentStatus = "<bean:define id="theStatus" name="detailService" property="status"/>";
or
String currentStatus = "<bean:write name="detailService" property="status" />";Is there a way to do this?.....
Any help pretty much appreciated

Java != JSP.
The <bean:define> and <bean:write> tags are custom tags meant to appear in the HTML section of a JSP file, as opposed to the scriptlet section. They actually get turned into java code as part of the translation process.
The <bean:write> tag naturally just writes out what you tell it to.
The <bean:define> tag defines a local variable, and gives it a value.
this should do it.
<bean:define id="theStatus" name="detailService" property="status" type="java.lang.String"/>
<%
String currentStatus = theStatus;
%>With the advent of JSTL, you shouldn't really need to use scriptlet code anymore. Personally I am for 0% scriptlet code in any jsp I write.

Hi All,
In my JSP I have something like a row of TextBox-----Combox-----TextBox Button--Add
When user clicks on "Add" I need to add exactly the same row as above.

Issue in converting Struts view to JSF view using struts-faces integration

Hi All,
I am facing a issue in my Sruts to JSF conversion application using struts-faces.jar integration library.
Need expert's help desperately as I am not able to use <s:form> tag in my new jsf page to call a struts action.
I want to call a struts action from my web page designed using JSF,
but it seems impossible without using <s:form> tag from struts-faces integration library.
Please suggest how to resolve this...
I am using WSAD 5.1 IDE with inbuilt Test environment WebSphere server
JSF Version: Sun's RI 1.1
Struts framework: 1.2.6
Struts-Faces Integration Library version: 1.0
I have configured a controller element in struts-config.xml file as has been suggested by different online
documents I studied:
<controller>
<set-property property="processorClass"
value="org.apache.struts.faces.application.FacesRequestProcessor"/>
</controller>
But configuring a controller does not allow my test server to start up properly and due to errors the ActionServlet also becomes unavailable.
If I comment the controller and start the test server it starts fine but then I cannot access the converted jsf page which contains the <s:form action="/xxxxx.do"> tag.
If now I get back to <h:form> tag instead of <s:form> tag with a <h:commandButton action="xxxx.do"/> for form submission in my jsf page, I see the html page generated with all components but now checking the html source generated I see
<form action="/contextName/jspFolder/sameDisplayedPage.jsf"> which is not valid and never gets called successfully.
I think someways I need to use the <s:form> tag with the controller configured properly to use the struts-faces integration library's request processor, to get things working. But HOW???
Following is the error I get if I use the <controller> tag element in struts-config.xml file and start the server.
This error appears on starting the server without accessing any application's jsp web page

Finally if I change my <s:form action="xxxxx.do"> tag to
<h:form>
<h:commandButton id="submit" action="xxxx.do" value="Submit" />
I see the webpage coming up in the browser (no controller element used in struts-config.xml file this time)
But in the html source of this html created from jsf I see
<form id="_id2" method="post" action="/training2/jsp/welcomeF.faces" enctype="application/x-www-form-urlencoded">
here form's action attribute is pointing to the same displayed page with the context name prefixed. I
assume it is because jsf could not resolve the "xxxx.do" action to anything so set it to the same displayed page.
May be I am wrong as usual...
Below is the simple struts jsp page which I need to convert to jsf page as I am converting only the View part of application.
I want to use the same struts beans and application logic at the back-end. At front-end I need UIComponents from JSF to be used.
Following is the struts jsp page
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" %>
<%@ taglib prefix="html" uri="/WEB-INF/lib/struts-html.tld" %>
<%@ taglib prefix="bean" uri="/WEB-INF/lib/struts-bean.tld" %>
<html:html>
<html:base/>
<html:messages id="messages" />
<font style="color:red; font=weight:italic; font-family: century gothic">
<html:errors/>
</font>
<BODY>
<P>Sample Struts and JSF integration example</P>
<P>This one is being displayed via Struts specific tags</P>
<html:form action="validateUser.do">
<bean:message key="label.name" /> : <html:text property="name" />
<bean:message key="label.password" /> : <html:password property="password" />
<bean:message key="label.age" /> : <html:text property="age" />
<bean:message key="label.city" /> : <html:text property="city" />
<bean:message key="label.address" /> : <html:text property="address" />
<html:submit property="submit" value="Show info via Struts" />
</html:form>
</BODY>
</html:html>
I have converted it into the following jsf page
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://struts.apache.org/tags-faces" prefix="s" %>
<f:view>
<HTML><BODY>
<f:verbatim><P>Sample Struts and JSF integration example</P></f:verbatim>
<f:verbatim><P>This one is being displayed via JSF tags</P></f:verbatim>
<h:form> 
<h:inputText id="name" value="#{userForm.name}" /><f:verbatim>

I've managed to get this working Ok from JDeveloper:

Basically you just have to fiddle around with Library settings to get this working OK.
As to how useful this is, well that's up to you - I'd not regard Faces + Struts as a must use combination, rather it's a can mix if you really need to. Look at Faces and Faces navigation first and see if that actually gives you enough before you start to look at mixing.

Should we use struts? Or another framework?

Hi all!
The company I work at is building a set of java applications (internal tools) and a website (what the clients will use). So our internal tools' users are our employees, and clients will use the website. Anyways, small introduction to get you situated. Also we use an object oriented database system (very high tech stuff I love it) and a JDO mapping to it. Now we are at the stage where all our internal tools are built, and we need to build the website. We will not have MASSIVE traffic to it, the nature of our product is more likely to be used often by a few clients. Our website will have all the standard stuff, like login, my account, mailing list, forum, news feed, menues, and a billing process for our clients, so we need some security.
All this to ask this simple question, given these parameters, do you think its a good thing for us to use Struts, or would we be ok with just jsp / servlets? For now, we have determined that using an application server is not necessary (we cant use EJB CMP because of JDO, and like I said we dont expect massive traffic), and we are looking for using templates also (Velocity looks good). The bottleneck for us is does it require a big learning curve, considering we are still newbies at jsp / servlets also. We would like to spend no more than 1 to 1 1/2 month to build the website.
Thanks for your thoughts, sorry for long post :)

The bottleneck
for us is does it require a big learning curve,
considering we are still newbies at jsp / servlets
also. Struts definitely has a ramp up time -- especially if you are extensively using the taglibs that it comes with (and which provide most of it's power, in my opinion). If you are still ramping up on servlets and such, struts can free you from doing stuff that you would have to figure out for yourself. E.g.
1. Proper handling of forms to provide validation and little detail things like repopulating them if something goes wrong
2. Displaying messages back to the end user.
3. Boring code to get html input from the user and put it into your object model.
Personally, I think that struts makes it much easier to make robust and consistent applications, especially if multiple developers are working on a project. Also, since it is fairly well known, it's a lot easier to maintain/pickup an app written in struts rather than a custom job. Of course, that means that you don't have as much job security...;)
So the question to you may be -- given what you know of what you need to do, what do you think will take longer -- building your own framework or learning one that has a fair amount of developer support. Of course everybody could do their own thing and you could spend a month mishmashing it to work together, which isn't unheard of either (although not recommended).

Saving results displayed on jsp into a text file using struts actions

Hi,
i am developing a web application using struts...the basic functionality of the system is to retrieve data from the database based on the search conditions given by the user. Hence for different search criteria there are different JSP result screens. Struts and persistence are being used. The user should be able to save/view the data loaded on the screen in a text file when he clicks on the save button.
I am supposed to write an action for fileoutput which can be used by all the result screens...instead of writing the same code in all the jsp pages...how do i go about it? I have already written an action class for the same but when i click on the save button a blank IE screen opens up instead of the open /save dialog box...i have also added mappings for the same in struts config xml file....any suggestions?

Again, you have posted to the wrong board. SignalExpress is an application written in LabVIEW.

How to get parameter and add it to hyperlink using struts tag?

Hi everyone:
There is a.jsp pass a parameter to b.jsp.How to get the parameter in b.jsp using struts Tag?I also want to add the parameter to a hyperlink in b.jsp.For example in b.jsp <html:link forward=.....>cxxxx</html:link>.How to add the parameter(get from a.jsp) to cXXXX in b.jsp?

Try this:
Copy A Request Parameter - You can create a new bean containing the value of a parameter included in this request. If no parameter of the specified name was included, a request time exception will be thrown - therefore, it is common to nest the use of this tag inside a <logic:present parameter="xxx"> tag to ensure that the parameter was really included. If there is the possibility that more than one parameter of the same name was included, specify the "multiple" attribute (and the resulting value bean will be an array of String values, instead of a single String).
<bean:parameter id="name" name="name"/>
And then just use <html:link> with paramId. No java code at all.
