RE: struts application with frames: top, side menus and main screen
Here is an example frame layout that maps to actions for each of the pages to be
displayed...
frameset rows=80,* cols=* frameborder=no border=0 framespacing=0
frame src=/header.do name=headerFrame scrolling=no noresize
frameset cols=120,* frameborder=no border=0 framespacing=0
frame src=/nav.do name=navFrame scrolling=no noresize
frame src=/main.do name=mainFrame
/frameset
/frameset
As for href links... I've used the following:
html:link page=javascript:nav('parameter');example 1/html:link
JavaScript that executes the href notice that the line
(paraent.mainFrame.location) identifies which frame window to display the returned
page
// JavaScript Document
function nav(id) {
var URL = /Display.do?item= + id + site=public
parent.mainFrame.location = URL;
}
Hope this helps

Re: struts application and skins
You could setup a filter that checked the requested domain name and set the root path to your resources into a ServletContext attribute accordingly.

Re: Struts application infrastructure choices
It should be fairly easy to implement this and do some performance testing. Your DAOs will be the only piece that changes to use RMI. You might try just using straight sockets because RMI is another layer on top of sockets which may slow you down. David From: Aymeric Alibert [EMAIL PROTECTED] Reply-To: Struts Users Mailing List [EMAIL PROTECTED] To: \Struts Users Mailing List\ [EMAIL PROTECTED] Subject: Struts application infrastructure choices Date: Sat, 14 Dec 2002 10:38:19 -0600 Hello, We are successfully running a large struts application. We designed it using a 'classic' architecture: - A Tomcat server running the application in our DMZ. - Use of Struts for our front-end and implementation of the DAO pattern to isolate our Data Access layer. Even if everything runs on the same server. - Use of DBCP pooling from Tomcat to access our Oracle database. Looking ahead, I can see needs for JMS connectivity or connection to various type of data sources within our company and to communicate with our partners. Also, our security team does not like having a Tomcat server in the DMZ accessing more and more internal information systems. We would like to take our infrastructure to the next level. I was thinking of introducing an Application Server within our firewall. It will implement our Data Access connectivity and the DAO on the Web Server will use RMI to access it. I am a little afraid of performance degradation by introducing RMI between the Web Server and Application Server. Also deployment will probably be more complex. Another solution would be to have both Web Server and App Server running on the same box in the DMZ. But that does not solve my security concerns. I don't have much experience with application servers and would not need the full features of a J2EE app server (at least not right now). Am I on the right path? Does someone have advices or best practices to follow?

Re: Struts application infrastructure choices
One way is to integrate via Oracle (or less expensive to operate PostgreSQL). What ever you need, you can cache or create an async. process to store the needed data in the DB, that is in the secured zone. Sort of a real time data ware house. So via Oracle create views or pl SQL on to other resources. Like create work tables, that are async. synchronized to other resources. This makes it very, very fast for DB access, at worst you get a bit stale data at times. It is a bit of pick your pain / gray issue.

RE: Struts application initialisation workflow.
I know the link http://husted.com/struts/ it is very good, but I am some difficulties to access information about Struts forum, and it is painful to see this message through mails like '[EMAIL PROTECTED]'. I learn a lot of thinks in the Struts API but I don't think that it is the best solution to understand a project. And this documentation is not updated for the struts1.1. For instance the process() method in the Action class has been depreciated. I think it is better to have access to the project's model (with class diagram, sequence diagram, or collaboration diagram). Unfortunately I have found only one struts diagram on http://rollerjm.free.fr/pro/Struts.html, but it doesn't deal with the Struts application initialisation. I am very interested in your diagram.

RE: Struts application initialisation workflow.
Thanks for your information. I don't remember that the RequestPorcessor must be defined in the struts-config file. I read the servlet 2.3 specifications and more precisely sections which deal with Lifecycle events. But this section doesn't explain if the container instantiates the struts controller before the listeners. The controller is defined in the web.xml too. I want to draw a diagram with ServletContainer(actor), ActionServlet, RequestProcessor, ServletContextListener and HttpSessionListener in order to explain initialisation(instantiation) and another diagram with a processRequest. You said that struts instantiates the RequestPorcessor, is it done in the init() method of the ActionServlet? Can you confirm that the processPreprocess() method is called on the execute() method of the ActionServlet. As I said in a previous mail, I don't think that reading struts API documentation is the best solution to understand initialisation or request process. An UML project model is better. Thanks. Sandra -Original Message- From: Robert Taylor [mailto:[EMAIL PROTECTED]] Sent: 03 July 2002 11:33 To: Struts Users Mailing List Subject: RE: Struts application initialisation workflow. Many the questions you ask can be answered by understanding the current servlet specification. And as you already mentioned, many of the Struts initialization questions can be answered by simply looking at the RequestProcessor methods. I've seen other threads which discuss in detail the initialization process. You may want to check the archives. http://www.mail-archive.com/struts-user%40jakarta.apache.org/ To answer your questions: ServletContextListeners are defined in web.xml, are instantiated by the container, are invoked in the order in which they are defined in web.xml. Struts does not manage them. See Section 10.2 Servlet2.3 spec. http://www.jcp.org/aboutJava/communityprocess/final/jsr053/ HttpSessionListeners are defined in web.xml, are instantiated by the container, and are invoked when the container creates or destroys a session and when a session is invalidated. Struts does not manage them. See Section 10.2 Servlet2.3 spec. RequestProcessor subclasses are defined in struts-config.xml, are instantiated by Struts, and are invoked upon each request to the Struts framework. See Struts 1.1 DTD (http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd) and RequestProcessor class. processPreprocess() is always true, unless you override it. See RequestProcessor class.

There are messages in the mailing-list archive that show how using Thread.currentThread().getContextClassLoader() instead of Class.forName() will allow you to put Struts.jar also into the default_path. As you have the Struts-sources available you could also modify it (make a search for forName( and then change). About the second problem: just configure correspondently. I do it all the time... eg. !-- start action -- actionpath=/start type=com.csg.cs.jst.strutssample.control.StartAction /action !-- welcome action -- actionpath=/welcome type=com.csg.cs.jst.strutssample.control.WelcomeAction forward name=success path=/home.jsp/ forward name=problem path=/homeProblem.jsp/ /action will have /do/welcome and /do/start route to different action-classes. hope this helps Alexander Jesse by the way: your mail has not come in HTML... -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Donnerstag, 28. Februar 2002 16:36 To: [EMAIL PROTECTED] Subject: Struts-Application in Default Servlet Context Hi, I want to combine a struts-application with a Vignette Content Management System. We are using a WebLogic 5.1, and Vignette puts its JSPs in the default context. What I want to achieve is to have the struts application integrated with the default context, such that I can use a forward to the JSP pages that have been put there by Vignette. Is that possible? I see the problem in incorporating struts.jar in some default_path, which is discouraged by the documentation. How can I do that? Challenge for Level 2: I want to use multiple action-classes with my application, for example such that URLs http:.../servlets/main.do http:.../servlets/part1.do http:.../servlets/part2.do all access different action-classes (and use different form-beans, of course). Am I on the wrong track here? Thanks for any help, -Ronald P.S. My apologies if this message comes as HTML.
