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.

What is struts and spring framework?

Hi all,
As mentioned in subject, I just know that they are frameworks for web applications. But how actually they work and is that any relationship between them with tomcat?

As mentioned in subject, I just know that they are frameworks for web applications. Struts is a web MVC framework; Spring is much more. It has its own web MVC framework, but it can work with Struts. It's based on inversion of control and aspect oriented programming techniques. Spring has support classes for everything from persistence, remoting, messaging, etc.
But how actually they work and is that any relationship between them with tomcat?Tomcat is a servlet/JSP engine. You can deploy applications using Struts or Spring on Tomcat.

Not able to create a web project with jsf or jsp or struts or spring

Hi,
I am trying to create a dynamic web project with jsf or jstl or struts or spring or any of web options available for a web project, but I am not able to do it.
When I choose any of these options, the wizard asks me to "select an existing jstl/jsf/Spring 2.0 library, or click Add to add a new library." and since it doesn't show any existing libraries there, I clicked on add new library. When I click add, it opens a new dialog box where it has two options :
1. to use spring/jstl/jsf lib from bea web site - when I choose this option, it tries to connect to the bea web site and gives me error that "connect time out". I don't know why it is not able to connect to the internet. I am not able to see the help also. There it gives error "The requested URL could not be retrieved".
2. to use libraries from an existing spring installation - I provide the path of a directory where spring lib are, but then it gives me error that this is not a valid installation.
On another machine, I am able to see the help contents, but still not able to get these libraries from the bea site.
Please help.
Thanks in advance,
Sushma

Hi Sushma,
The issue you are facing has been addressed and will be part of the next release. For the current release, please follow the steps listed below.
Send an email to [email protected] with details on specific facets you are trying to enable on your project.
You will be provided with a url where you can download the required jars and details on how to manually add the jars to the workspace which will prevent the download on demand scenario.

STRUT, COocoon, Spring framework

I'm about to start self-learning Cocoon, Strut, and Spring framework.
I was wondering which to start. After a quick glance at Jakarta site, I noticed that the description of Cocoon is very similiar to Strut. Is Strut a replacement of Cocoon..and I also noticed that Cocoon is not listed as one of the project under Jakarta. has it been stop?
And which framework should i start with? some suggest that i learn strut, since strut is more popular..but some say Sping is better than Strut, and people are shifting toward Spring framework. Basically..i'm confuse as where to start..i will probably learn them all (though probably not in detail for some framework)

Cocoon is a high level Apache projet. It is not part of Jakarta.
http://cocoon.apache.org/
It is tough for anyone to tell you which framework you should be learning because they all have their uses. Yes, Struts is by far the most widely used.
However, JSF is becoming the new standard now that Sun is pushing it. So don't count it out.
Sorry I can't help you more with your decision. What framework to use/learn is a topic often debated. Only you can decide which one makes the most sense for you.
Good luck.

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.

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>
</f:verbatim>
<h:inputSecret id="password" value="#{userForm.password}" /><f:verbatim>
</f:verbatim>
<h:inputText id="age" value="#{userForm.age}" /><f:verbatim>

</f:verbatim>
<h:commandButton id="submit" action="#{user.facesAction}" value="Show info via Struts" />
</h:form>
</BODY></HTML>
</f:view>
I am very hopeful of some answer from respected group experts, please help me.
I am in urgency of course but would not push for immed. response like other, just want some help for sure that is going to
be extremely valuable to me. Anticipating a helping hand...

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.

Using Struts with JDeveloper, BC4J and OC4J 9.0.2

Is it feasible to use Struts with JDeveloper 9.0.2, BC4J 9.0.2 and OC4J 9.0.2? We have an application that uses the BC4J JBO tags in version 9.0.2. We wish to use Struts and we want to retain the use of the JBO tags. Is there a way to do this without upgrading to 9.0.3?

Here are two related questions:
Can we upgrade to oracle9iAS 9.0.3 yet still use JDeveloper 9.0.2 and BC4J/JBO 9.0.2?
Can we upgrade to JDeveloper 9.0.3 and BC4J/JBO 9.0.3 yet still deploy to oracle9iAS 9.0.2?

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.

Can I use Struts Validator Plugin's html:javascript tag?

Hi:
Is it possible to incorporate the client-side validation using Struts Validator
Plugin's tag <html:javascript>?
i.e.
1) Insert the following tag to A.jsp and define a taglib:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<html:javascript formName="aForm" staticJavascript="true"/>
2) Define validation.xml as follows:
<form-validation>
<formset>
<form name="aForm">
<field property="aField"
depends="required">
<msg name="required" key="FieldMissingError"/>
</field>
</form>
</formset>
</form-validation>
3) Insert the onSubmit event in aForm:
<netui:form action="SubmitAForm" style="border-width:1px;" onSubmit="validateAForm(this)">

Instead of writing something like this -
<p class="logos">Logo1<a href="...></a></p>
<p class="logos">Logo2<a href="...></a></p>
<p class="logos">Logo3<a href="...></a></p>
<p class="logos">Logo4<a href="...></a></p>
<p class="logos">Logo5<a href="...></a></p>
<p class="logos">Logo6<a href="...></a></p>
Why not have something like this -
<div id="logodiv">
<p>Logo1<a href="...></a></p>
<p>Logo2<a href="...></a></p>
<p>Logo3<a href="...></a></p>
<p>Logo4<a href="...></a></p>
<p>Logo5<a href="...></a></p>
<p>Logo6<a href="...></a></p>
</div>
with CSS like this -
#logodiv p { ... }
