Struts and Rich Clients
Hi! I'm currently writing a rich client database application which performs database manipulations by using XML and sends it to the web server (running struts). I'm looking for a sample application for both of these: 1. rich client app 2. struts+xml I tried checking these on javasoft, onjava, javaworld and theserverside sites but still cant find a good example and reference.

AW: Struts 1.1
What is the V/S Toolkit and where do I find it? Thanks ! -Ursprungliche Nachricht- Von: Cedric Dumoulin [mailto:[EMAIL PROTECTED]] Gesendet: Montag, 11. Februar 2002 19:01 An: Struts Users Mailing List Betreff: Re: Struts 1.1 There is now a multi-applications support. Some new classes have been added. A lot of methods from the servlet have been moved in different classes, like the RequestProcessor class. Tiles need now to provide a subclass of RequestProcessor in order to catch calls to forward/include. Also, instruction to use this subclass is specified in struts-config rather than in web.xml.

Re: JDO
Hi Martin, I believe that JDO can be used successfully - I'm currently planning to use Castor directly or with EJBs running under JBoss. The thing I like about it is that it also does rather reasonble XML serialization. Thus I can write an XML Schema to reflect a persistant object-tree then automate building the objects. That's rather cool for separating off the interface from persistence as I can demo a Strut's based app. without any Database.. then just map it into a relational-database. Doing things this way also buys you at least some Schema-based validation since Castor will generate a validate method based on your schema. There are others on the list who suggest this validation is too course to be of much use.. but it is a start.. anc Castor is open-source. My impression is that there are places where it could be enhanced but is generally a solid product. I've worked with other OR mapping tools with regard to EJBs. At that level mapping to the database is pretty rote and therefore a good place to use a tool - who wants to write all the JDBC for this? Efficiency usually is not as good as JDBC so these tools usually add caching to improve that. In my application I don't think this will be an issue while development speed is. The key thing is to know where to use the tool and realise that you shouldn't get too esoteric with mapping complexity. Hope this helps, Jon Martin Farrell wrote: Hi I am interested in introducing JDO or some form of Object-Relational mapping into my application. I've had a hunt around and think the best option is probably castor(http://castor.exolab.org) although Teds page lists some other options. Has anyone had any experience in using JDO with struts? If so what sort of object model did you use? What other open source options should i consider? Am i better off sticking with JDBC until JDO is more mature?

RE: page do not refresh
In fact, the value in the session is ok, but it seems that the proxy is

System.out.println(SelectSiteAction [Start]);
String strCellIDParam = request.getParameter(CellID);
System.out.println(CellID received in URL + strCellIDParam);
// Report any errors we have discovered back to the original form
// Is there a currently logged on user?
reqReoUser reoUser = (reqReoUser) session.getAttribute(User);
if (reoUser == null) {
if (servlet.getDebug() = 1)
servlet.log( User is not logged on in session
+ session.getId());
return (servlet.findForward(logon));
}
// Get Datasource configured from struts-config.xml
DataSource dataSource = (DataSource)
servlet.getServletContext().getAttribute(Action.DATA_SOURCE_KEY);
java.sql.Connection conn = null;
try
{
// Get a connection to database from the Generic Pool
conn = dataSource.getConnection();
// Put a session value specifying the Site ID on which every

if (session.getAttribute(Site) != null)
session.removeAttribute(Site);

So the question is, how do I set this parameter in the poolman.xml file???

RE: Pre and Post Processing
Thanks for the info. For things like drop lists, we will be using a custom tag, as most of our drop lists come from a standard validation group XML transaction to our back end. We pass in a group serial, and it returns a set of values for the drop list. (Plus I don't particularly like the idea of having SQL in JSPs) A colleague of mine is currently investigating custom tags with a view to producing a simple interface for these drop downs. Keith suggested putting it in the ActionHandlerI'm not particularly comfortable with that, as that then ties the two web pages together. I'd like (ultimately) to have our back end drive which page comes next, rather than having it in the struts-config.xml, but to do this, I need to have each page autonomous, and have it get all it's pre-requisites itself. Jeff's mail (Framework Questions) was interesting as it raises a similar point.

Subject: Re: page do not refresh
Frédéric,
If the query string is different between the two requests, it is not likely
to be a page caching problem. The query string is part of the URL, so things
that cache pages by URL will see the two requests as two different URLs.
Try using the request scope, rather than the session scope, for passing the
object from your Action to the JSP page. This is preferable unless you need
to keep the value in the session for some other reason. However, if it does
need to be in the session, it doesn't seem like the action is replacing the
value in the session and needs further review (perhaps you could post the
code that puts/gets the value in the session).

RE: Traffic
It's going to get worse. Nevertheless, you will never be able to manage the number/technical level of users in an open forum. SERVLET-INTEREST became too congested with basic setup and config questions by people too lazy to search the archive for an answer (and how many scores of questions have been asked here regarding ActionForm in just the past 2 weeks?) so a few guys created ADVANCED-SERVLET-INTEREST and began regulating the level of users. One thing that helped, however, was being brutally blunt with obviously lame users and telling them to STFA (search the f*cking archives), STFW (...web) and RTFM. This started a couple of flame wars, and the Sun moderator finally had to banish a few people, but the quality and quantity of posts changed considerably for the better.

Re: internationalization
You are on the right track. 1. Ensure that MySQL supports using a unicode character set. You may need to define this at install time, that is how oracle works. 2. When request parameters come in, they are assumed to be ISO-8859 (or whatever your platform default is) and encoded from there to unicode. You need to tell the web container that the input stream coming in from clients is actually in UTF-8, not ISO-8859. If you are using a 2.3 servlet container this trick is much easier. There is a struts parameter to the controller servlet will have some impact here, try setting the content parameter to be text/html;charset=UTF-8. If you are not using a 2.3 servlet container (e.g., old tomcat) your work will be somewhat more involved. Also try reading http://tagunov.newmail.ru/i18n/i18n.html good luck. --Michael Christopher Cheng wrote: I am struggling with double byte characters with the JSP On the struts jsp form, I am putting %@ page contentType=text/html; charset=UTF-8 % on the top META http-equiv=Content-Type content=text/html; charset=UTF-8 in the head I got some question marks when I print the characters in the console by System.out.println(request.getParameter(parameter1) Or save those character to file The same thing happens with the data retrieved from MySQL displayed on JSP.

I Sam would like to use the User Agent to identify the Sam client type (e.g. where desktop or a mobile phone) and Sam send out either HTML content or WML content. Sam I come up this idea, I am wondering if there are Sam better solutions: Sam Have a different forward name, different path for each Sam device type: Sam For example, in struts-config.xml Sam actionpath=/logoff Sam type=org.apache.struts.webapp.example.LogoffAction Sam forward name=successHTML Sam path=/indexHTML.jsp/ Sam forward name=successWML Sam path=/indexWML.jsp/ Sam /action Sam And in the perform method of my action code, I have Sam something like: Sam if user agent is desktop Samreturn (mapping.findForward(successHTML)); Sam else Sam return ((mapping.findForward(successWML)); I wonder whether it would be useful to have something like this (feel free to imagine better naming API conventions): action path=... name=... type=... forward-group name=success choice match=.*mozilla.* path=/thing.html / choice match=.*kbrowser.* path=/thing.wml / /forward-group /action Then, the mapping.findForward() method would be overloaded with one that takes a match string. The match attribute in the choice element is a regular expression, which matches against the parameter. In this case, the parameter value you would provide would be the User-Agent header. This would allow view selection to be abstracted out of the Action class. Any view could be updated to get an alternate rendering, without changing the Action code. The caveat being that you'd have to agree on what always provides the match expression in each Action. The User-Agent is a good choice, but other applications might use something else. -- === David M.

Re: Problem with html:link forward...
Thanks David, here is my form bean definition: form-beans type=org.apache.struts.action.ActionFormBean form-bean name=userMaintForm type =application.presentation.struts.formbeans.UserMaintForm / /form-beans This is for the page that I am linking to from the menu page.

Editing a database record best practice?
A common scenario I run into is having a web application where the user needs to edit a database record. The simplest approach I can find is this - 1.) Load the db record into a bean. Copy the bean props. to the form for display. Put the dbbean in the session. 2.) Show the form, when the user presses save, validate the form, make sure, if possible, that the form primary key fields are equal to the dbbean in the session primary fields. 3.) Have the dbbean do an update statement. In order to do this properly, the dbbean needs to have kept the original db values so they can be put in a where clause. This insures that we are changing the record exactly as we loaded it. If somone made a change before the page was submitted, the update would fail. Is that the best approach to accomodate a sort of optomistic locking? Are there any tools to autogenerate the dbbean objects? I was thinking of trying to do it with an xml schema and XSLT to transform the schema to java objects. Thoughts?

Extra Path Info Problem!!! HELP!!!
Hi Guyz, I'm having a really strange problem wiht struts ... I looked around in the mailing list found a lot of people had similar problems .. but I couldn't find any solution for it. The problem relates to use of extra path info. I have a URL which looks something like this http://myserver.com/servletname/extrapathinfo/actionname I've defined the url mapping in the web.xml as /servletname/*. I was hoping that struts will try pick up only the last component of the URL as the action name I would be able to use the extra path info in my servlet. But it doesn't work that way, instead struts tries to look for an action with the name /extrapathinfo/actionname ... I would really appreciate any idea/leads in solving this problem ... been stuck-up with this for sometime now .. :-( Thanx in advance, VD. __ Do You Yahoo!? Send FREE Valentine eCards with Yahoo!

Maybe you meant that you wanted to WRITE a PDF file from JSP? Loading a PDF file from a JSP is no different than loading any other web page from JSP. If the client browser has the Adobe Acrobat plugin installed, any hyperlink to PDF files will spawn the PDF file in the requesting browser. You may need to ensure that your server is configured to accepct the PDF mime-type, but other than that, it's a simple deal. To write PDF's dynamically, there is a Java library that you can obtain that is free. You'll have to dig for it though, cause I simply cannot remember the name or where to get it. There are also numerous commercial libraries that assist with writing dynamic PDF's on the server. - Cody [EMAIL PROTECTED] on 02/12/2002 04:27:32 AM Please respond to Struts Users Mailing List [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] cc: Subject: Loading pdf files using jsp Hello, I want to load a PDF file from JSP.

Re: help: %.. how do i convince them to learn JSP?
I have no problem being convinced that tags should be used for generating complex items on a web page. The one concern I do have, relative to using tags, is the extra processing required to generate simple things. I have seen pages in industrial environments where the page may have 50-100 elements displayed (and no this is not a problem with the design this is a real application requirement!). Using a tag to generate labels and text input boxes seems like it would add a significant compute load on a server that is servicing 100's of people. The same situation applies when you are dealing with pages with fewer elements, but are being served up to 1000's or 10,000's of users.

URGENT: Null Strings in Websphere
Whenever we have a String value in our forms, and the value is not set (), it is getting sent back to the jsp as null. By null I mean the actual string, and not an empty object.

Re: help: %.. how do i convince them to learn JSP?
I think it depends on, what you're trying to achieve: If i remember it corrctly, the tags inside the jsp get inlined when the jsp is compiled: So the performance problem boils down to a problem of objectcreation and -deletion, which nowadays is handled quite good by most modern jvm. If you want to fetch labels from property-files, then the properties are cached in a per-jvm manner. If you really run into performance issues, i don't think they come from using taglibs but from the requirement to mix-in the labels dynamically (maybe to perform internationaliation or - even worse - based on user-rights or preferences): So maybe you should try to think of some sort of pre-processing (generating templates with the right labels in it and then using a simple template-engine or maybe even simple bean-tags(%=..%) to populate the pages. And maybe you should have someeone think about the requirement for exposing ten thousands of users to 50 -100 elements on just one page - has to be a very special audience...;) - Original Message - From: Bob Williams [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Tuesday, February 12, 2002 4:05 PM Subject: Re: help: %.. how do i convince them to learn JSP?

Re: Editing a database record best practice?
we are using a similar approach with ejb's, that produce value object's instead of database records: We have generic ValueObjects that are filled into the formBean using reflection (You can do something similar with result-sets using the meta-data: as long as you don't mind tying your bean-properties to the database-field names...): along with the data, a timestamp is transported inside the value-object: So only the ValueObject with the last timestamp can make an update on the ejb (with only some exceptions (CLOb/BLOB-fields which get specific update methods) we make global updates, we just set *all* values from the value-object into the ejb. Coming back from the form the process works the other way round: copying the values from the ActionForm into the valueObject and then passing it to the ejb for update... This sounds like a lot of copying: We first had the ejb's producing ValueObjects that extended action-forms with all the fields needed in the form: we ended up with having to package the struts-libs with every EJB caused by this mixing of business-object and view-layer (resulting in a lot of classloading-hassle: Fortunately you sometimes get real errors for bad design-decisions..) - so we ended up with this generic ValueObjectLayer that clearly separates the view from the Business-objects. Instead of using ejb you can try jdo (e.g castor, or intelliBO) - I'm not really sure, wether the need for such a neutralizing layer vanishes with this, but I think they will give you at least some handy tools to write the Data-Access-layer without having to write the sql by yourself. greetings stf - Original Message - From: Ryan Cornia [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, February 12, 2002 2:56 AM Subject: Editing a database record best practice? A common scenario I run into is having a web application where the user needs to edit a database record. The simplest approach I can find is this - 1.) Load the db record into a bean. Copy the bean props. to the form for display. Put the dbbean in the session. 2.) Show the form, when the user presses save, validate the form, make sure, if possible, that the form primary key fields are equal to the dbbean in the session primary fields. 3.) Have the dbbean do an update statement. In order to do this properly, the dbbean needs to have kept the original db values so they can be put in a where clause. This insures that we are changing the record exactly as we loaded it. If somone made a change before the page was submitted, the update would fail. Is that the best approach to accomodate a sort of optomistic locking? Are there any tools to autogenerate the dbbean objects? I was thinking of trying to do it with an xml schema and XSLT to transform the schema to java objects. Thoughts?

Re: Editing a database record best practice?
Hi, I've been thinking about this and have just arrived at the point you left behind! OK, the issue is that there is a data layer that holds EVERYTHING. And its all normalised inside databases and is pretty hard to utilise within your business code. So we create a business layer which loads up rows and parts of rows to perform the logical updates and operations required. We use EJB, CMP, OR, JDO whatever. We then have a presentation layer that is user oriented, mixing language varient information, multi-table information, business calculation information, security and so on. Each page/screen only holds the information needed and it holds it in a user friendly form (say Strings for ease, as in Struts). User-MiddleTier/business-database Network bandwidth and the marshalling times are an issue (maybe). Lets say we are using EJB, local interfaces from mid tier to DB, so its as quick as currently possible (ahem). Now the presentation data is held in strut form objects. I recon it is these that should be used as the data transport from mid to gui and back. It means we are only shipping the data we need. But we are putting presentation logic within the mid tier - ie objects that are purely there to populate data for a specific screen. I know this is fast and scalable. BUT, I also know that I have to stick struts.jar into the EJB container (usually they have an obvious common libs place - eg for jdbc drivers). Do we do this? A sacrifice of time against elegance. Hmmm. I guess the really OTT answer is: User/GUI = Form Object, all strings Mid Tier = Value object holding equivalent fields for each form field, but in native data type, but no struts code. DB = EJB, local interfaces. Just answered myself, anyone else got a point of view? Jonathan ps With respect to the original thread, I don't hold any state info in the session because of scaleability, timeout, and state transition issues (back button, multiple browser windows etc). It does mean an update is read for display, and then read for validate/insert. But I recon the DB is there to be used. I do hold user info in the session, but not activity state.

This sounds like a lot of copying: We first had the ejb's producing ValueObjects that extended action-forms with all the fields needed in the form: we ended up with having to package the struts-libs with every EJB caused by this mixing of business-object and view-layer (resulting in a lot of classloading-hassle: Fortunately you sometimes get real errors for bad design-decisions..) - so we ended up with this generic ValueObjectLayer that clearly separates the view from the Business-objects. Instead of using ejb you can try jdo (e.g castor, or intelliBO) - I'm not really sure, wether the need for such a neutralizing layer vanishes with this, but I think they will give you at least some handy tools to write the Data-Access-layer without having to write the sql by yourself. greetings stf - Original Message - From: Ryan Cornia [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, February 12, 2002 2:56 AM Subject: Editing a database record best practice?

Copy the bean props. to the form for display. Put the dbbean in the session. 2.) Show the form, when the user presses save, validate the form, make sure, if possible, that the form primary key fields are equal to the dbbean in the session primary fields. 3.) Have the dbbean do an update statement. In order to do this properly, the dbbean needs to have kept the original db values so they can be put in a where clause.

Struts gotchas
I've run into several Struts gotchas while I'm learning/using it for the first time. I was wondering if anyone knows of a web reference(s) that covers some of these? I've since solved the problems, but if there was some documentation on some of the most common ones, I might be able to avoid some in the future. For example, changing the scope of an action in the struts-config.xml from request to session has solved a problem or two. :) Another example is when I had JSPs located down a directory hierarchy, I had to change the struts-config.xml action path to reflect that hierarchy. I thought I could just keep it as the *.do name (without the .do). Most examples always have the JSPs at root level. These are newbee issues, but they did take some time to figure out. Ted, your site, husted.com has Struts docs on it right? What about posting a sort of gotcha FAQ? I can help you put something together if you want and I'm sure some people here can contribute on some of the things they've gotten stuck on and then solved. ?? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: CLASSPATH, env, lib, jars and all that
This is a great question. I've been thinking about the same issues. I've been working on several projects here and I've migrated from Tomcat to IIS/ServletExec to Orion. At one point, I put most of my jar files in WEB-INF/lib which were found by IIS but not by Orion. Then I started working with another developer on one of the projects and we needed to share the same environment. So we put the jar files out on a network directory. He uses Ant to build, I use a bat script which sets the CLASSPATH at the beginning. Currently we're using Sun's servlet.jar. Any better suggestions would be appreciated!

One thing complicating it all, which I'm afraid will trip me up when I start using newer versions in the future, is all the jar files, often multiple copies of which are held by the different java installations, e.g. xalan.jar or its classes is in tomcat, j2ee, ant. Or jdbc2.0-stdext.jar. Even just now when installing Wintec Inc. Struts Validator, it comes with all its own copies. Most of this stuff is in J2EE, but somehow I doubt anyone would advise me to put that in my CLASSPATH, would they? So how does Joe Struts organise his/her environment? Do you set up a profile which allows you to run ant tomcat and rigorously delete unnecessary jars? Or do you just tweak every build.xml you have? Or do you chuck everything in tomcat-4.0.1/common/lib?

html:submit and bean:message

What I want to do is this: html:submit value=bean:message key=constant.value1/ bean:message key=label.value1/ /html:submit Setting the label works fine, but the value attribute either complains about quoting or puts the literal bean:... string in as the value. I have tried various combinations of single, double, and escaped quotes, but I can't find the correct combination. Is this even possible? What I am trying to accomplish is to not have to specify the same constant in multiple places (in this case in the jsp page which has multiple html:submit tags and the Action routine that does the processing.)

[ANNOUNCE] stxx - struts for transforming with xml and xslt
stxx - 0.7 http://www.oroad.com/opencode/ Struts for transforming XML with XSL (stxx) is a rewrite of the struts framework to support XML and XSL . stxx sit's on top of struts, extending it's existing functionality to allow Action classes to return XML that will be transformed by an XSL file. The idea of stxx is to remove the need to be use JSP and TagLibs for the presentation layer of this framework. However, stxx does not force you to go the XML/XSL route, both technologies should work side by side. So, adding XSL support to struts is ALMOST as simple as adding the following tags to your struts-config.xml file: action path=/welcome type=com.oroad.stxx.example.ExampleWelcomeAction scope=request forward name=success !-- the transform tags take the XML returned by the Action and transform them. The transform tag used is determined by matching the user agent against the name attribute (or default if nothing matches) -- transform name=default path=/login.xsl/ transform name=Mozilla path=/login_netscape.xsl/ transform name=MSIE path=/login_msie.xsl/ /forward /action stxx features: - Enhances the forward tag in the struts-config.xml file to allow one to many transform tags. These transform tags represent the XSL file to be used depending on the user-agent of the browser accessing struts - A new class variable for the Action class, A JDOM Document, which you use to append your data in your Action class too. This Document object will be transformed by the XSL file in your transform tag. - stxx automatically flattens the ApplicationResources file to XML and attaches it to the Document object returned by the new Action class. - stxx also automatically appends the request parameters and attributes, as well as ActionErrors as XML to the Document object. Please note: stxx is a work in progress, however, at this point I've been using it for about 4 months and it works great for me, I realize it might not fit everyone elses needs. Please send me feedback, opinions, complains, etc. Also, to those other people (2 that I know of) who have downloaded the previous version of this that I had, this is an almost complete rewrite of what I had earlier. This version is not the rewritten struts code, but a seperate package that is a lot leaner, quicker and better. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

But I really don't like the HTML select implementation. So I use a custom tag to fill in select/option lists. In fact I have to use this tag throughout my application so I made it very generic. My select/option lists almost always come right from my database. So I made a tag that takes a SQL statement as an attribute, the name of the field that I want as the option value as the 2nd attribute, and the name of the field I want displayed in the list as the 3rd attribute. The tag class builds a stringbuffer with option value=[field1][field2]/option strings for each row returned from the SQL statement. Then I use the struts form/action classes to verify the result of submitting the form. At 05:35 PM 2/11/2002 +, you wrote: Hello. I'm new to struts, and I'm having a discussion with one of our designers about pre and post processing in web pages. Previously, we have used the standard JSP way of creating pages, with lots of code in the top and body of pages, in order to access functionality we have exposed in some Java beans. These Java beans wrapper XML services provided by our Forte 4GL back end. Say we have a form which accepts customer details. I can see how the Struts mechanism allows us to put the code that was previously at the top of the next JSP page into an ActionHandler, which decouples the flow of pages quite nicely, and we have a nice way of doing post processing on the contents of a page. However, if we have a page that has to display a list of addresses for a customer, and we have to run some code to get the list before we can display it, where should this code live? Should it be in the ActionHandler with the previous page's post processing, or is there a better place to put it? Or would you suggest writing a custom tag to perform the pre-processing?

App Design
Hi all, I am thinking of structuring an application as follows, and would appreciate any advice and ideas of how to do this: There will be two frames. First is a navigation frame where the user presses a button to determine the JSP that is loaded into the second frame. Each possible JSP for the second frame will have form. If a user is entering data into the form, and then presses a button on the navigation frame to go to a different jsp/form, I want to save the partially entered form data from the page the user is leaving. Then when the user goes back to the first page they can continue where they left off. I have been prototyping an idea; the navigation frame uses JavaScript to submit the form and redirect the old page to the new desired page. So far I have accomplished that when the form is submitted the action does not really do anything, so the form data is saved in the bean. But how do I accomplish the redirect? Any ideas are greatly appreciated. Mark Glatzer *** Disclaimer This message is intended only for the use of the Addressee and may contain information that is PRIVILEGED and/or CONFIDENTIAL or both.

RE: iterate tag usage
Henry,
an array does not extend java.util.Collection. The iterate tag expects a
Collection (which contains a 'iterator()' method). So you have to convert
the array into a collection, either by simply not using arrays in favor of
collections, or by implementing an additional method like:
public Collection getListCollection()
{
return Arrays.asList(listArray);
}
BTW: I would avoid arrays.
Cheers,
Moritz.
I have a jsp page with the following code:
logic:iterate id=regList name=RegForm property=listArray
bean:write name=regList property=listArray/
/logic:iterate
and in the RegForm.java java bean, we have the following code:
private String[] listArray;
public String[] getListArray()
{
return listArray;
}
But when I query the page, I got error:
javax.servlet.ServletException: No collection found
Why and how to fix?

RE: URGENT: Null Strings in Websphere
We had a similar problem. Although we were actually getting spaces back from our DB, we were seeing null displayed on our jsp's. We fixed it by explicitly initializing our String fields in our result beans to rather than letting them default to null. I don't know *why* this worked, since you'd think the original null values would be overlaid when a field's setter was called, but for whatever reason, it solved the problem...

By null I mean the actual string, and not an empty object. This is making validation of these fields fail. Has anyone seen this and found a work around.

RE: iterate tag usage
Hehe, nope. ;-)
Look: the return value of the getXYZ() method must be a
java.util.Collection, Iterator etc. but _not_ an array. By the way: your
code would not even compile.
private Vector listVector;
// A Vector implements the Collection interface. That is good.
public Vector getListVector()
// This works. Vector.
Have fun!
Moritz.
P.S.: What the hell is VectorString?
Thanks for your info! Do you think the following will work?
logic:iterate id=regList name=RegForm property=listVector
bean:write name=regList property=listVector/
/logic:iterate
private Vector listVector;
public VectorString[] getListVector()
{
return listVector;
}
Thank you again!

Howto redirect/forward to other webapp with one config file?
I've read in the list that it's possible to do a forward with Struts from one WebApp to another. But according to the struts-config1_0.dtd, the forward paths are all relative. My question is: have those forwards actually been redirects or is it really somehow possible (without using some server bugs)? Then my next question would be: is there a nice way of doing a redirect to another webapp on the same server? By nice I mean that the redirect is done by only providing the WebApp path, but not the server itself? Let's say, I have two servers, a test server and a production server. My app shall be the same on both servers, which means that I don't have to say something like action path=/appSwitcher type=mystuff.AppSwitchAction forward name=continue path=http://mytestserver/OtherApp/do/login; redirect=true/ /action for the testserver, and action path=/appSwitcher type=mystuff.AppSwitchAction forward name=continue path=http://www.mydomain.com/OtherApp/do/login; redirect=true/ /action for the production server.

Re: Pre and Post Processing
As I understand the implementation of html:select, I would have to return a
collection of something. Collection of beans? One of my select lists has
370 school names in it. The last thing I want to do is to create/pass
around a collection of 370 objects instead of one StringBuffer (actually
converted to String at the end of the tag class).
If there's another way to use html:select as I have used the tag, please let
me know. Plus, how is it a breach? Doesn't struts use custom tags? Why
can't I use a combo of struts and my own tags?
I actually have to do a repost with this page too so I even use a usebean
tag along with my struts form tag at the top so that I can have a selected
option. Basically the user picks a school name and the form reloads with
the school's address filled in for the user.
Suggestions welcome.
Here's my code snipet:
jsp:useBean id=schoolAddressForm
class=edu.cccs.energizer.SchoolAddressForm scope=session/
html:form name=schoolAddressForm
type=edu.cccs.energizer.SchoolAddressForm action=forms/schoolSave.do
select name=suffix onChange=getAddress();
%
//only select it if it exists
String suffix = ;
suffix = schoolAddressForm.getSuffix();
if (suffix != null)
{
if (suffix.length() 0)
{
%
option value=%= suffix % SELECTED%= schoolAddressForm.getName()
%/option
option value=--/option
option value=Select One Below:/option
% }
} else {
%
option value= SELECTEDSelect One Below:/option
% } %
ene:optionlist
sql=SELECT school_suffix, name FROM schools ORDER BY name
value=school_suffix
item=name /
/select

Serious breach of MVC though!

I'm relatively new to struts too. But I really don't like the HTML select
implementation. So I use a custom tag to fill in select/option lists. In
fact
I have to use this tag throughout my application so I made it very generic.
My
select/option lists almost always come right from my database. So I made a
tag
that takes a SQL statement as an attribute, the name of the field that I
want
as the option value as the 2nd attribute, and the name of the field I want
displayed in the list as the 3rd attribute. The tag class builds a
stringbuffer with option value=[field1][field2]/option strings for
each
row returned from the SQL statement.
Then I use the struts form/action classes to verify the result of
submitting
the form.

Say we have a form which accepts customer details. I can see how the
Struts
mechanism allows us to put the code that was previously at the top of the
next JSP page into an ActionHandler, which decouples the flow of pages
quite
nicely, and we have a nice way of doing post processing on the contents
of a

However, if we have a page that has to display a list of addresses for a
customer, and we have to run some code to get the list before we can
display
it, where should this code live? Should it be in the ActionHandler with
the
previous page's post processing, or is there a better place to put it?
Or
would you suggest writing a custom tag to perform the pre-processing?
Thanks for any thoughts,
Tim.

Best Approach for Database Access?
Could you kindly provide guidance on the best approach to implement database access.? I have encountered various schools of thought in my reading, that suggest extracting the business logic and database code from the jsp into a jsp bean or ejb or servlet.

RE: Best Approach for Database Access?
Hi Paul I follow this design practice for both EJB and non-EJB applications. The ones marked with * live at the application server JVM. (1) Non-EJB environment === JSP - ActionBean - ServiceBean - DaoBean - DB (2) EJB environment (BMP or Session) JSP - ActionBean - * ServiceBean - * DaoBean - DB (3) EJB environment (CMP) = JSP - ActionBean - * ServiceBean - DB Notes: == ActionBeans are the action classes of Struts DaoBeans are normal JavaBean classes which knows how to communicate with the DB, ie all SQL code goes here. In (1), you need to take care of transactions on your own. The ServiceBean in (1) is a normal JavaBean, but an EJB in (2) and (3) In (3), we do not need a Dao, since the CMP does all that work for us.

RE: Pre and Post Processing
Is there an alternative to breaking the MVC?? We have to populate drop downs from the database. So I call the DAO from the JSP through a Helper Object (will convert this to a tag) and use the returned collection to populate the drop down using the html:select tag. For efficiency, we may store this collection in application scope. The alternative (I think) is that we create an action for this purpose and call the database from within the perform method which returns null?? Isn't that a lot of overhead to populate drop downs? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 12, 2002 11:49 AM To: Struts Users Mailing List Subject: Re: Pre and Post Processing Serious breach of MVC though!
