RE: Validation a form
I don't understand why it does not work.
It crashes only when the validate method is called and must return an error.
Is sqlQuery begins with select it works fine and i got to the result page.
Do i need to write a jsp page in case of error? (i already have one where i
forward to when an exception is called in my Action class)

it works when there is no error but not when i've one

The above code looks OK -- what about it doesn't work?
Note that you *must* specify an input attribute on your Action, so that
Struts knows where to send the user back to.

FW: Indexed tags problem
The way I have solved this problem currently is to create a method in the
form that forwards to the object within the form.
e.g.
public PersonField getPersonField (int index) {
return (PersonField)person.getPersonField(index);
}
It is a work around rather than a fix.
I intend to have a look and see if I can discover a better solution.
cheers

Onderwerp: RE: Indexed tags problem
I have finally solved the problem, and it was due to the
nested property.
So ignore my last posting or take note of the word probably !
Is there currently a way to access nested properties stored
in forms when
using indexed tags??
e.g. for automatic updates
form.getDetail(index).setProperty()

I moved the getPersonFields() method into the personForm

So it is probably not because of the nested property!
i.e.

any thoughts, (I have read through otherpostings, regarding session etc.. )

Get request and the Action servlet
I would like to use Struts with an action that is initiated by following a link, rather the form-based approach that I can see in the documentation. I would also like the ActionServlet to parse the URI and instantiate my bean with the information from the URI. Is this possible? Sorry if this is a FAQ - I've had a trawl thru the docs, honest.

HTML Base Tag using SSL
We have a problem using the html:base tag when displaying a Struts JSP Page under SSL. SSL is configured on our web server (BEA WebLogic) to listen on the default port (443). When the JSP page is displayed in the browser the source HTML code shows the base tag with port 80 instead of port 443 (or blank). If we change the web server configuration so that SSL is listening on a different port (eg. 7002) then the base tag is correctly rendered with :7002. The problem may be arising because when we try to set the URL with :443 in the address the browser automatically removes the :443 and it looks like the html:base tag assumes SSL is on port 80 when it resolves it.

I'm new, need some tutorials and maybe some advice
Hi all, I just signed up and looking for some tutorials on struts. I installed it on Linux with Apache-Tomcat config. There is a sample application in there, however it would be maybe easier to go through some tutorials first. Any suggestions ? Also, I'm in the process of doing a little web site for myself. It's basically only presentation of data for now. I have a little confusion there. As far as I understood the specifications, servlets ( controllers ) are responsible for data extraction from the database and JSPs for presentation. So what should I set up as the index page , a JSP that forwards the request to servlet and servlet responds to JSP again or to use a servlet that sends data to JSP ? Also. is it a good technique to have the JSP ( beans ) extract data from database ? In this case, how do I get to the connection parameters if I don't want to hardcode it and maybe use web.xml file to hold the connection parameters ? All responses are welcomed. Thank you. Jf
Struts Design Question
Hello all, I downloaded Struts last week and have enjoyed playing with it. I've come upon a design problem and I was hoping some folks on this list could help solve it. I've had no luck finding an answer in the mail archives. I want to maintain a list of songs. Through a web interface, I want to add a new song, edit information about an existing song (composer, artist, etc) and also delete a song. Under the covers this will do some sort of database insert, update and delete, respectively. The forms for adding a new song and editing an existing song are practically identical. They contain the same field names with the difference being edit pre-populates the fields with the existing values of a song whereas the fields are blank for add. Question #1: Can one ActionForm suffice for both add and edit form pages? My gut says yes, but I want to make sure. Actions. In the simplest scenario, I could create separate actions for all operations. I'd have AddSongAction, EditSongAction and DeleteSongAction classes each with their own logic in perform(). This would work, but there's something that bothers me about having three different classes performing operations on one entity. It seems like overkill. DispatchActions. I saw the post about using DispatchAction to have multiple methods in a single Action class. I really like this approach, as I could have insert, update and delete methods in my Action class. However, the input= attribute in the action mapping definition (in struts-config.xml) is shared for all of them. So if I have separate addsong.jsp and editsong.jsp form pages sharing the same Action, and a validation error occurs, Struts can only return to one (whatever input= is). So this won't work. Question #2: Is there a happy medium between these two approaches? One idea that I haven't worked through is using one songform.jsp page for add/edit/delete. Calling songform.jsp?method=add would produce a blank page for entering a new song. Songform.jsp?method=editid=1234 would populate the form with values from a song whose id = 1234. From here one could edit or delete the selected song. In Struts I'd use the DispatchAction to pass all add/edit/delete requests to one Action class. Because all were using the same form, the input= attribute problem above would be avoided. Question #3: Will this approach work? Can anyone offer a better solution for this problem? Thanks for the feedback. -ryan
RE: Struts Design Question
Yes you can do the add/edit all on the same form. If have a database generated code or key you can put that in a hidden field. When in the action examine the form or request obj to see if that key is there, if it is you have a modify, if not add the record. Have you page that lists the songs pass a the code/key as a parameter to the SongForm.jsp. Then you can use the jsp:useBean as follows: jsp:useBean id=SongForm class=com.mypackage.SongForm scope=request jsp:setProperty name=SongForm property=songKey param=songKey / /jsp:useBean Then to pre populate the form you can make a DataBase call in your form setSongKey() method and use the result to set the other values in the form. For a delete you can have a second form on the same page (with its own submit button) that has the songKey set into the SongDeleteForm and the submit is mapped to a DeleteAction that just uses the key to delete the record. I am new at the struts stuff myself, so these may not be the best ways to accomplish what you are trying to do, but I know it works. So anyone else please feel free to critique. Aaron -Original Message- From: Shriver, Ryan [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 08, 2001 9:30 AM To: '[EMAIL PROTECTED]' Subject: Struts Design Question Hello all, I downloaded Struts last week and have enjoyed playing with it. I've come upon a design problem and I was hoping some folks on this list could help solve it. I've had no luck finding an answer in the mail archives. I want to maintain a list of songs. Through a web interface, I want to add a new song, edit information about an existing song (composer, artist, etc) and also delete a song. Under the covers this will do some sort of database insert, update and delete, respectively. The forms for adding a new song and editing an existing song are practically identical. They contain the same field names with the difference being edit pre-populates the fields with the existing values of a song whereas the fields are blank for add. Question #1: Can one ActionForm suffice for both add and edit form pages? My gut says yes, but I want to make sure. Actions. In the simplest scenario, I could create separate actions for all operations. I'd have AddSongAction, EditSongAction and DeleteSongAction classes each with their own logic in perform(). This would work, but there's something that bothers me about having three different classes performing operations on one entity. It seems like overkill. DispatchActions. I saw the post about using DispatchAction to have multiple methods in a single Action class. I really like this approach, as I could have insert, update and delete methods in my Action class. However, the input= attribute in the action mapping definition (in struts-config.xml) is shared for all of them. So if I have separate addsong.jsp and editsong.jsp form pages sharing the same Action, and a validation error occurs, Struts can only return to one (whatever input= is). So this won't work. Question #2: Is there a happy medium between these two approaches? One idea that I haven't worked through is using one songform.jsp page for add/edit/delete. Calling songform.jsp?method=add would produce a blank page for entering a new song. Songform.jsp?method=editid=1234 would populate the form with values from a song whose id = 1234. From here one could edit or delete the selected song. In Struts I'd use the DispatchAction to pass all add/edit/delete requests to one Action class. Because all were using the same form, the input= attribute problem above would be avoided. Question #3: Will this approach work? Can anyone offer a better solution for this problem? Thanks for the feedback. -ryan
Poolman under Tomcat 4
Has anyone using Poolman configured it properly for Tomcat 4? Since it supports both JNDI and a static call for retreiving the datasource, it works well with layered applications. I have it running under Tomcat 3 well enough. But configuring it to play nice with Tomcat 4 is eluding me. I have the requisite poolman support JARs in the Tomcat lib (jdbc2_0-stdext, jta, xerces), except for poolman.jar, which is in its own folder. The poolman.xml is in the poolman folder, and both the JAR and the folder and the JAR on the classpath. I'm using findDatasource(), but the Tomcat log reports it can't find the class. If I move the poolman.jar to the Tomcat4 lib orthe WEB-INF\lib, a Network Error: Peer reset connection error is exposed by the browser, and Tomcat suddenly quits. My guess is that TC4 is not finding the poolman.xml (whereas TC3 does). If anyone sorts this out, I'd love to hear about it. Meanwhile, if anyone else is trying Poolman under TC3, I found that it really does want Xerces for the parser, so swap out the Tomcat default. It is also really-not-kidding about having the poolman.xml on the server's classpath. Having it a lib folder isn't enough. But after that, it works just great.

Advice on how to implement the following:
Hi, I need a bit of advice on how to implement the following. I am creating a page that holds a list of item names along with their description. So far I created a vector that holds an array of items and then passes it to a Struts page in the request scope. The page then iterates the array and then produces the page. So far no problem. Now I need to add a text field in which the user can input prices for these items. Then I need that form submitted to my actionservlet for processing. This is where I get lost. I thought of adding a price field to my item class and then as the vector is iterated on the page I create a textfield binding it to the price field in the bean. But when the page is submitted I don't think the vector will be passed to my action servlet for parsing. Any help is appreciated Alex
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.

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.

Re: Poolman under Tomcat 4
As another data point, I use resin and tomcat3. I typically configure poolman locally for each web app. That is, I put poolman.jar into each WEB-INF/lib directory and an application specific poolman.xml into each WEB-INF/classes directory. Things also work if I configure poolman globally by putting poolman.jar into the /resin/lib or /tomcat/lib directory, and putting poolman.xml into /resin/classes or /tomcat/classes. (this poolman.xml has configuration for all web apps). Things get complicated if one tries to mix local and global configs on the same app server.

html:image tag, property attribute?
html:image src=../../images/sendandsave.gif property=guess/
results in
input type=image name= src=../../images/saveasdraft.gif
which is not what I'd expect from looking at the source for ImageTag:
public int doEndTag() throws JspException {
// Generate an HTML input type=image element
HttpServletResponse response =
(HttpServletResponse) pageContext.getResponse();
String tmp = null;
StringBuffer results = new StringBuffer();
results.append(input type=\image\ name=\);
results.append(property);
results.append(\);
..
Is there something else I have to do to get the name attribute set?

ActionServlet.addMapping() persistence
Hi all... I want to write an Action that will add mappings to the ActionServlet on the fly. Am I correct in thinking that any ActionMappings and such that I add in this way will not be persisted, and that I also have to modify struts-config.xml if I want the mappings to be available for future restarts of my servlet engine? Also, is there a way to specify multiple config paths in the ActionServlet so that i can have more then one struts-config.xml in one webapplication? So, for example, I would have a webapp test, which has test/WEB-INF/struts-config.xml. If I added something later to it, test/subtest, with its own new Actions, could I make a file test/subtest/WEB-INF/struts-config.xml and have that file ALSO be read by the ActionServlet on startup? I suppose I could update struts-config.xml and then tell the ActionServlet to reread it in the Action I talked about in the first paragraph...I'd like to be able to seperate this out, if possible, to make the seperate components of my webapplication seperate. The problem with putting this all into individual webapps is that I want the session to be passed from one part of the webapp to the next. Any thoughts?

Scalability
Hello All, I've been working with Struts for sometime now, but now I run into another question. Has anyone had any issues with Struts not being scaleable? Have you performed any stress tests on your applications? I really like Struts, but I'm getting feedback from other developers that don't feel that Struts is a very scaleable framework. Can struts concurrently handle 1000+ users and not have a crippling affect on your app server? These are some feedback questions I'm curious about and thought I would get some concrete answers from developers of Struts. Have a good one, Steven application/ms-tnef
Re: how to submit a form with different parameter value
One way would be to have a hidden field in the form named action, and then have some JavaScript event handler on the two image buttons that set the value to be transmitted for the action property to either continue or goback appropriately. Essentially, this is the same thing you would do with static HTML.

Re: Open a new window after an action
Windows are a client side thing, so you deal with them in Struts the same way you do with static HTML. * You can specify a target attribute on the form, which will cause the response to be displayed in a window identified by the target value. * To open a window with no decorations, you'll need JavaScript that does a window.open() call. You should be able to find info on any of the tutorial sites about JavaScript. Craig On Wed, 8 Aug 2001, Mustapha Essalihe wrote: Hi every body, After executing my perform method i want to open a new window to show the result. I use the html:link tag with attribute target as : html:link page=/adminNews.do?action=ViewNews target=_blank paramName=nouvelle paramId=id paramProperty=id bean:message key=button.view/ /html:link this work correctly, when the action is exetcuted a new window is opened and the content is displayed. The probelm is that i want to open the window without toolbar, location, status like in javascript window.open() method. How can i do that with struts ?
Re: Why would jsessionid not appear?
The jsessionid path parameter will only be added if the servlet container does not know whether your client supports cookies. How Tomcat handles this (probably typical of others): * On the first response in a session, send the session id both ways (cookie and encoding). * If the subsequent request comes back with a cookie, turn of URL rewriting for the remainder of this session. * If the subsequent request comes back without a cookie, keep on rewriting.

Re: ActionServlet.addMapping() persistence
On Wed, 8 Aug 2001, Becky Moyer wrote: Hi all... I want to write an Action that will add mappings to the ActionServlet on the fly. It's kind of fun to do stuff like this :-), but there's a standard action already available for you -- check out the org.apache.struts.actions.AddMappingAction class. There are a few other interesting standard actions in the same package. Am I correct in thinking that any ActionMappings and such that I add in this way will not be persisted, and that I also have to modify struts-config.xml if I want the mappings to be available for future restarts of my servlet engine? That is correct. Alas, there is no portable way to tell the servlet container you want to *write* to a resource inside the web application archive. Also, is there a way to specify multiple config paths in the ActionServlet so that i can have more then one struts-config.xml in one webapplication? So, for example, I would have a webapp test, which has test/WEB-INF/struts-config.xml. If I added something later to it, test/subtest, with its own new Actions, could I make a file test/subtest/WEB-INF/struts-config.xml and have that file ALSO be read by the ActionServlet on startup? There's an XML trick that lets you do this without needing to modify Struts. Consider that you've got a struts-config.xml file divided into three parts (form-beans.xml, global-forwards.xml, and action-mappings.xml) stored in the /WEB-INF directory. They can be combined automatically by doing something like this in struts-config.xml: ?xml version=1.0? !DOCTYPE ... [ !ENTITY part1 SYSTEM form-beans.xml !ENTITY part2 SYSTEM global-forwards.xml !ENTITY part3 SYSTEM action-mappings.xml ] struts-config form-beans part1; /form-beans global-forwards part2; /global-forwards action-mappings part3; /action-mappings /struts-config Obviously, you can extend this concept to any reasonable separation of struts-config.xml into subordinate files. I suppose I could update struts-config.xml and then tell the ActionServlet to reread it in the Action I talked about in the first paragraph...I'd like to be able to seperate this out, if possible, to make the seperate components of my webapplication seperate. The problem with putting this all into individual webapps is that I want the session to be passed from one part of the webapp to the next. The other approach would be to keep the individual pieces of struts-config.xml in separate files in your source repository, and use the Unix cat tool (or the DOS copy tool using plus signs) to concatenate the pieces together as you deploy the web app. Any thoughts? Thanks, Becky Craig
Weblogic related question- javax.servlet.jsp.JspException: No getter method for property...
I am moving a Struts-based application from WebLogic 5.1 to 6.1 and I am
encountering some strange errors. 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. I have verified
with the debugger that at runtime the Collection exists and it is populated
with the expected objects. I am not really sure what is going on... The only
thing I can think of is that this method does not exactly conform to the
JavaBean spec- it does not set/get the same type of object. When doing a
set, you pass it a TimeStamp but for the get it returns a formatted String
(see below). However, the naming conventions are followed correctly. Is this
a problem?

Re: session question
There is no way to approach this problem as you currently are. You should be
able to achieve the same effect however, but you will need to restructure
your approach. Not knowing the details of you situation I would advise you to
think in terms of having an action initialize your action form and set it as
a request (or session...) attribute.
Good Luck,
Troy

Struts on Websphere on AIX box
Hi,
We have being using struts for a while now. We got it running on VAJ 3.5.3 .
Also, on Websphere 3.5.3 on NT box. But now when time for actual deployment
came ( which is on AIX Box ) , struts is giving a hard time . We are getting
following error :

-//Apache Software Foundation//DTD Struts Configuration 1.0//EN from
struts-config.xml. step as mentioned there but then it says DTD not
registered.
We have tried lots of work around but nothing worked till now. Have anyone
tried the same got it working. Please let us know. Struts version used is
1.0 ( final release).
Its urgent !
Thanks, in advance

Re: Can't get setter method(s) for indexed property right. Pleeze help
Marcel,
I walked through code example submitted by Warwick Boote to get past
issues/concepts with setters for indexed properties. The only change I
made was to add a second field to the form. So, if your list is named
properties, you would have second field on the form called property also.
My property set method added an item to the properties vector (if it did
not already exist on the vector)... I don't know if this is the best way
to do it, but it worked.
Brian
Here's the message Warwick posted:
Here is a hacked version of the code posted by David Hay previously. The
code here will compile and run - a Vector is populated then displayed.
After a post, the vector is retrieved from the form and then System.out is
used to show its size.
This should help others that are having problems with indexed tags. You'll
need to point your browser to somthing that looks like
http://localhost/struts/ShowParameters.do once you've copied all the files
into the correct locations.
There were two issues with the way i was trying to do it, firstly it seems
that unless the scope of the form is set to session (or not specified) it
doesn't work and secondly because i was using a different id for the name
in the logic:iterate / html:text tags (when i set them to
parameter it worked).
logic:iterate id=parameter name=FieldsMapForm property
=parameterList
html:text name=parameter property=attributeCode indexed=true/
br
/logic:iterate
actionpath=/mapping
type=com.eurobenefits.dta.presentation.FieldsMapAction
scope=session
name=FieldsMapForm
validate=false
forward name=viewmappings path=/DefineFieldMappings.jsp/

Subject: what setters do i implement in an indexed tag ?
I've created a page using indexed tags (neat stuff!).
Here is what is currently working for me:
o If i populate the form's vector, values from that vector are displayed in
the jsp
Here is what it not working:
o when the form is posted back, the vector is null (in the struts perform()
method)
I suspect i haven't implemented some sort of setter within the form but i
can't find an example as to what method should be implemented. I've tried
ArrayList and using parameterList instead with no different result.
Thanks,

Construct context-relative URL in Javascript?
I've seen Craig posted how something like html:image page=/images/a.gif/ will get translated to img src=/myapp/images/a.gif But I need to create a context-sensitive URL in Javascript. The reason for this is that there are multiple buttons on my form/page and in the action handler function for each button I need to set the form's action to the appropriate action for that button click before submitting the form. So I think I want a way to do get at info in Javascript that is the equivalent of what is returned by javax.servlet.http.HttpServletRequest req.getContextPath() So that something like this can be done in Javascript this.form.action = contextPath + /graphs/fullgraph.jsp (or .do instead of .jsp or whatever) So is there some way with a Struts tag to put the context path on the generated page using perhaps an invisible control that would be set to have the context path as its value? Then one could assign the invisible control's value for the the context path to a Javascript variable and use it in something like the code snippet above. I also need to do some other stuff in the Javacsript (eg set the target attribute of the form tag using a generated value as well). So I think I really need to use Javascript to do this. Or am I approaching the problem in a way that is totally wrong?

newbie question
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. Regards. - Debasish __ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo!

Re: beans:write bug?
This is a consequence of the JavaBeans introspection mechanism. The getter and setter must be getting and setting the same type for them to be recognized as property accessors.

We have a bean with properties where the setter takes a float, and the getter returns a string. Using expressions and scriptlets, this all works fine. For instance, I can write the following for a bean contained inside another: %= HagBean.getProduct().getPrice() % and a formatted string with the price will appear. However, when we try the equivalent bean:write, bean:write name=HagBean property=product.price / struts tells us that we are mismatching types with a float and String. Is this a bean:write bug? As I understand beans, setter methods are not even required. I find it odd that bean:write seems to be assuming the type of the setter method and then becoming unhappy when it gets the type returned by the getter method.

Re: Staging Pages/Action form question.
The Struts answer to both of these questions is use an Action. The Action classes are where the various pieces come together. In the first case, your action will invoke methods on business-logic objects and populate the form with the results. Then it will forward to the appropriate JSP page to display those results. In the second case, the search criteria will be presented to an action as a form bean. The action will then pass this data to business-logic objects, which will perform the search and return the results. After performing any transformations necessary to make the results more easily digested by a JSP page, the action once again forwards to an appropriate JSP to display them. Take a good look at the example application that comes with Struts, and Ted Husted's Strut by Strut article at: http://www.husted.com/about/struts/strutByStrut.htm for more details on how it all works. -- Martin Cooper - Original Message - From: Prior, Simon [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, August 06, 2001 2:02 AM Subject: Staging Pages/Action form question. Hi Guys, I have the following scenarios and to design for and wanted to know how you approached the following problems: 1. I have a page that will have dynamically generated menus populated with entries from a database. My first question is how do you stage the pages? - can you use the action form to retrieve the information to populate the menus from the database ? I was thinking of using the action forms constructor to call an ejb to ultimately retrieve the information but didn't know whether this was the best way of approaching the problem. Do you guys have any suggestions? 2. I also have a search page where the user enters the search criteria and then submits the query, at this point I was going to put the search criteria on the session and have the results page pick up the search criteria, carry out the search and then display the results. How do you guys do this? If I was to use an action form for this in a manner similar to the above scenario the constructor would retrieve the search criteria from the session and execute the query thus 'staging' the page. Can the action form access the session? If not, how do you guys do it? Any help would be most appreciated. Thanks in advance, Simon. For optimum solutions that save you time, visit www.ds-s.com.

Again, the documentation is very sparse on this subject. The basic principle is that every data source you define is made available to your application's Actions as a servlet context attribute. The first data source receives a default name (so you can just call servlet.getDataSource() with no argument from an Action). Beyond that, you have to assign specific names to the data sources, like this: data-source ... key=myname .../ and then you can reference that particular data source from an Action: DataSource ds = servlet.getDataSource(myname); or from a JSP page as an application-scope bean named myname. The latter is how you would access it from DBTags. Thanks Jeff Bird Craig
Re: Newbee: design question
You don't have to create a form bean if you don't want or need to. In your example, the form bean would only have one property, and that property came directly from a link (minimizing the risk of invalid values, and hence the need for validation in the form bean), so you could just use request.getParameter() instead if you wanted to. Regarding unifying access to form fields and parameters, I'm not sure what you're getting at. If a form bean is used, Struts will populate it from the request parameters regardless of how the request was submitted. So long as the form bean has a property corresponding to each parameter name, the form will contain all of the request parameter values when your action class is called. -- Martin Cooper - Original Message - From: Andreas Leitner [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, July 25, 2001 1:13 AM Subject: Newbee: design question Hi, I am pretty new to tomcat/struts but nevertheless trying to create a simple application using the two (; I have troubles getting my design right, maybe some people on this list could give me some hints, they would be greatly appreciated. The idea is that I have a DB backend that stores a bunch of documents identified by an integer. Now the user can click on a link and view the document (that's the first step). Now the link looks like this: html:link page=/viewDocument.do?documentId=33view doc with id 33/html:link Now, what I want to happen when the user clicks this link is: Run a controller that checks if the documentId is valid, and if so, retrieve the document from the DB and store it somewhere in the request scope, then forward to the actual viewer, otherwise forward to an error page. The forwards will be done using local forward mappings in the config file, in order to seperate buisness logic from presentation code. What I don't understand is: Do I have to create a Form class for this action? The documentId comes as an Parameter in the request scope and struts won't fill out the Form anyway (cause there is not form). The example that came with struts did create a form class in this case, that's why I am confused. My thinking was that I could just simply add a custom Document class to the request scope, which the actual viewer would then read. Another issue: Can I unify access to Forms fields and Parameters? For my example it would probably not make a lot of sense, but it would be neat (from a theoretical POV) if it would not matter if the user just clicked on a link with parameters or he submitted a form. As long as the both contain the same fields/parameters, struts could always fill out a Form class. Or am I missing something? Regards, Andreas
New To Struts
Hi, I am new to struts and for past one week I am trying to find tutorials and materials regarding struts. The only thing I got is some tutorial in jspinsider.com. I understood the model of struts, but when putting it in to code, I am facing problem at very basic step. All I see in tutorials is they have explained how to use struts in tomcat server. But I am using weblogic5.1 server. I have did all the settings as per directed for tomcat. I understand there must some different way of deploying struts in weblogic server. Can anyone please guide me through as what I should do to run my basic application? What all installations do I need and where should be they placed? I am really vexed up looking for these things on net. This mailing list is my LAST REOSRT. Thanks and Regards, Nitu.
Re: New To Struts
You must not have visited the Struts home page, which should have been your *first* resort. :-) http://jakarta.apache.org/struts/ There you will find: * A link to the Struts User Guide * A 'Resources' link, which will take you to a page listing several tutorials and articles on Struts. * An 'Installation' link, which will take you to a page detailing specific installation instructions for over a dozen different containers, including WebLogic 5.1. -- Martin Cooper - Original Message - From: Nitu Singh [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, August 08, 2001 5:18 PM Subject: New To Struts Hi, I am new to struts and for past one week I am trying to find tutorials and materials regarding struts.

Re: New To Struts
The following might help you. ramakrishna. * Ted Husted has links tutorials, example webapps, and code (custom tags, etc.). http://www.husted.com/about/struts/ A Walking Tour of Struts (at the bottom) walks you through the Struts example webapp. http://www.husted.com/about/struts/scaffolding.htm If you want to stay pure MVC, then you can have your home page go through the controller servlet. Struts has a connection pool that you can use for database connections. You configure it in the struts-config.xml file. David --- [EMAIL PROTECTED] wrote: Hi all, I just signed up and looking for some tutorials on struts. I installed it on Linux with Apache-Tomcat config. There is a sample application in there, however it would be maybe easier to go through some tutorials first. Any suggestions ? Also, I'm in the process of doing a little web site for myself. It's basically only presentation of data for now. I have a little confusion there. As far as I understood the specifications, servlets ( controllers ) are responsible for data extraction from the database and JSPs for presentation. So what should I set up as the index page , a JSP that forwards the request to servlet and servlet responds to JSP again or to use a servlet that sends data to JSP ? Also. is it a good technique to have the JSP ( beans ) extract data from database ? In this case, how do I get to the connection parameters if I don't want to hardcode it and maybe use web.xml file to hold the connection parameters ? All responses are welcomed. Thank you.

Re: New To Struts
Thanks a lot, And I did visit the home page for struts(and that's where the problem started). 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. 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? 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? 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?

Struts Tomcat 4.0
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? 2) Doesn't look like Tomcat 4.0 supports EJB. Does it? 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. 4) From one of Ted's emails I think I should use Poolman to create database connection pool in Tomcat 4.0. Right? 5) What's equivalent of Weblogic Time APIs? Tomcat workers, right? 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? 7) Does Tomcat support JMS? 8) Which one is better - Log4J or LogKit (which is part of Avalon project from Jakarta)? 9) What's the difference between 'Struts' 'Turbine' (which is another Jakarta project)? Pros Cons? I apologize for the length of this email. Thanks in advance for your time. - Ajay
