Re: Struts & UML ....
Hi All, Thanks for the response, but that is not what I am asking, the question is in a UML there are specific layers e.g. presentation layer, business layer, data layer. The MVC 'Model View Controller is within this UML? The question is where in UML is the MVC located? I thought that it was in the presentation layer, but I am unsure if the 'Model' part of the MVC is located in the business layer? I hope that the information I have provided is sufficient enough for a response. Thanks again.

Struts Example using jdbc/odbc
Hi All, Has anyone got an example of Struts web application that retreives data from a jdbc/odbc? I have created a .mdb 'Access' and put this into a web application, but seem to be missing some source code. I have updated my web.xml and struts-config.xml, but unsure of the source code in the action class and in the servlet and how to reference the data in the .mdb? That is why I would like to check with an example to compare the source code to see what I have done wrong. Thanks for everyones time and looking forward to your response.

Struts & UML ....
Hi all, Could some one give me a quick simple solution or a good detailed example of the following. My understanding so far of Struts is not so bad I think, but when looking at the MVC and how it works, I would like to put that into order with UML. I could image that there is a million of UML examples and MVC, but I would like a simple answer on a Struts MVC and UML. Now the question is after the actionservlet controller sends a perform() to the action class. is this action class in the MODEL??? and if so, where in the UML view is it?? To me it looks like most of the MVC is based in the presentation layer is that correct? Could someone enlighten me with a good clear answer please. Thanks for everyones time and have a great day.

Struts UML
Hi All, The UML is split into 3 layers in the http://www.husted.com/about/struts/ I have always pictured this way and the UML looks well presented. If you where going to look at the UML in a way to see where the MVC is going to take part in this, would that be in the presentation and business layer, is that correct? Second if that is so, is the 'model' part of the MVC would be located in the busines layer of the UML? So what is the 'model'part of MVC the perform()'Action' to get the request from the Data Layer of the UML e.g.EJB,DB2 etc is that correct? Thanks for everyones response to my questions, and Martin Cooper thankyou for the detailed response to Model question, if you have anyother detailed information on Struts, I will be happy to take it as well.

Kick start to Struts
Hi all, Which comes first the chicken or the egg? I need to know when creating a struts web application which comes first, creating the java component first, then build the html and convert to jsp? that is the question I need to get started into my own web application through struts. I would really like as much feed back as possible in the best professional approach to this. As I have so much enthusiasm, but not enough knowledge in this area. This sort of information that I request is second nature to web designs and programmers I gather, but I am new to the game. Thanks to all those listeners and most importantly thanks to the perfect responses from Ted and Craig. Kind Regards Rodney Smith -- Sent through GMX FreeMail - http://www.gmx.net
Database.xml or other avenues
Hi All, I have seen how database.xml works with Struts-example.war and that was good, but I would like to test the same sort of database on Access .mdb If I put dummy data into the .mdb, where do I put the .mdb? do I put this in the WEB-INF section with the other .xml files? I have created a folder in the subdirectories called DATA and I have configured my build.xml to copy this .mdb to the main section of my web application. I need to state an action mapping in the struts-config.xml file and also mention that in the web.xml? and if so where? Is there any information that could help me configure that database not only to retreive information but also to add information into this. Or is it better to create two .mdb one to send information to a database and the other retreive data for logging onto the web application and have the two .mdb communicate with each other in some way to exchange data or to update? That sounds easy but is there any tips on doing this or any examples that could assist me with this? Thanks for your time and have a great day.

Building Web Application
Hi All, I have sketched out the frame work for my web application. I have configured my Struts .xml files and put this in my Tomcate 3.2.2 and compiled this and this has worked. The question is what I am doing the correct way of building a web application and if not which is the professional way. I have created all my .html pages first and the links work, then I have converted most of my html pages to .jsp, I would like now to make a login process to my web application and that intails java files and java forms etc. Then intergrating the java files into my web application. Is this the incorrect way of approaching a web application? I would appreciate a bit of advise with that. Thanks Craig for your information on ActionServlets it has helped, I have read all the information on Struts-example.war and that was really good. But the example that I got mine out of was out of a book called Profession JSP 2nd Edition and that was called ch21. Thanks for your time and looking forward to your response.

URL links & ActionServlet
Hallo, Firstly I would like to thank Ted Husted for all his help with me getting a better understanding of Struts, as I am a new to this area a lot of the information that I have found is great but not detailed enough to understand some of the process as what Ted has mentioned is perfect, thanks again Ted. OK the questions are still coming as follows. I am using Tomcate3.2.2 and runing of a localhost: In the example I am using I have the index.jsp page and in that I have two html links, one goes to get registered with the web application and the other is logon to the web application. If I click on logon this takes me to the logon.jsp page. When I client clicks on this as this is a .jsp this does not go to the actionservlet as that is not a .do action 'is that correct'? instead that just calls the viewer of logon.jsp??? or does this go direct to the JAVABEAN by passing the ActionServlet to get the logonform.java??? Now if the client clicks on the registation URL link on the index.jsp it comes back with a editregistration.do on the browser bar, in this case, as this is displaying the .do, does that mean that actually has been to the ActionServlet to JAVABEAN and comes back with the registration form display or does this just go to the viewer and retreives the registration.jsp form, with out going to the ActionServlet?? I understand that if the person sends a request 'A' to logon to the web application it needs to be a .do and needs to go to the ActionServlet 'B' I think that it goes the same with the registration as well. It is when they are asking for the forms to submit is where I don't know where they are stored or if they need to be retreived from the JSP viewer etc. Thanks for your time and I hope that can get another good response. Many thanks Ted and have a great day. Kind Regards Rodney Smith -- Sent through GMX FreeMail - http://www.gmx.net
Struts Fundermentals
Hallo, I have a question that I should really know, but I honestly could not answer without getting confirmation of other Struts users. I have been asked many times about what is struts and I have responded it is a open source framework useful for building web applications in Java Servlets and Java Server Pages. But then they say what is Struts a application or what? I was lost for words I thought it was claster of class, but unsure and I didn't think it was a software. Could some one please enlighten me, so a can spread the correct information on Struts and how good it is. Kind Regards Rodney Smith -- Sent through GMX FreeMail - http://www.gmx.net
Accessing JDBC-ODBC from Struts
Hi I need some direction on how to incorporate JDBC-ODBC into my struts and where the ODBC should be stored in my application. Also how to reference that in my Action Servlet, I am a little unsure about this area, but would appreciate some feed back or documentation that will simplify my work.
