Re: showing nested collections in a JSP
2005/8/17, [EMAIL PROTECTED] [EMAIL PROTECTED]: I think I can figure out how to display the tables using the nested:XX tags, but cant figure out how to display the nested collection by radio button. I guess I need to understand how to index a collection dynamiclly. I know JSTL is the preferred way, but I'm stuck with only the struts tags to build Don't know if I undeerstood well your need, but I would use client logic, as javascript functions, to realize this behaviour. Why don't make use of the 'style' property of visual elements to hide/display them depending on radio button clicking events? -- TREMALNAIK - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Pre-population of html:select tag using multiple html:option tags
Hello Everybody,
I am trying to pre-populate a jsp page form via the reset function of an
ActionForm. All values appear correctly in the form except the select /
option combinations. Could somebody have a look at the following and
provide some pointers? (Have not used html:select before...)
The ActionForm:
public final class ProccessPropertiesFormAction extends ActionForm
{
private String listlength = 20 ;
private String usesig = 0 ;
private String signature = ;
private String fullname = ;
private String replyto = ;
private String maxwidth = 72 ;
private String maxheight = 20 ;
private String defsort = date ; --- used to create the select
...
public void reset(ActionMapping mapping, HttpServletRequest request)
{
User user = (User) request.getSession().getAttribute(user) ;
listlength = Integer.toString(user.getPagesize()) ;
if (user.getUseSig())
usesig = 1 ;
else
usesig = 0 ;
signature = user.getSignature();
fullname = user.getRealname() ;
replyto = user.getReplyto() ;
maxwidth = user.getMaxwidth() ;
maxheight = user.getMaxheight();
defsort = user.getSortby(); // -- (this is date, subject,
etc)
and the JSP Page:
...
html:form action=/ProcessProperties
tr class=row1
td align=leftbean:message key=properties.replyto//td
td align=righthtml:text size=30 property=replyto//td
/tr
tr class=row2
td align=left
bean:message key=properties.defsort/
/td
td colspan=2 align =right
html:select property=defsort

Problems declaring DataSources
Hello All, I have the following datasource declared. The password, URL and user name as well as Database name (on the URL) are corrected and I have them tested. Here it is: data-sources data-source key=ds1 type=org.apache.commons.dbcp.BasicDataSource set-property property=driverClass value=com.mysql.jdbc.Driver / set-property property=url value=jdbc:mysql://localhost:3306/Test / set-property property=user value=antunes / set-property property=password value=antunes / set-property property=description value=Test_db / set-property property=readOnly value=false / set-property property=autoCommit value=false / set-property property=loginTimeout value=5000 / set-property property=maxWait value=5000 / set-property property=maxActive value=500 / /data-source /data-sources However, when I put it in my struts-config.xml I have the erros bellow.

I've never used JSF so firstly, is this now the way to go? Roughly, Shale is to JSF as Struts is to JSP: it provides a framework which supports best-practices application development with features that are outside of the scope of the basic Sun technology. Roughly that's pretty accurate :-), although there is one level of internal difference that you will want to be aware of. JSF includes a controller servlet (like Struts and other MVC frameworks), and supports other controller features like navigation, itself. Shale builds around the edges to add value (functionality and/or ease of use improvements), without any attempt to redundantly implement features that JSF provides by itself. One place I *don't* see Shale going, by the way, is to become yet another library of JSF components. There will be a few such components that integrate directly with Shale features (like the ones that integrate the Commons Validator facilities), but the whole idea of a standard component API is that you should be able to use *anyone's* components with it. If you're going to use JSF, you should probably check out Shale. I would agree with this ... especially for new app development. You can use struts-faces to connect JSF to Struts, but if you have no deep Struts experience, you wouldn't be gaining much of anything, and in fact you'd lose all the benefits that Shale has by virtue of learning from several years of Struts development experience. The integration library should be primarily considered as a tool useful in a migration strategy. Secondly, where can I find out more? And finally how steep is the learning curve? There doesn't appear to be the Shale equivalent of http://struts.apache.org Shale's website, by the way, is at: http://struts.apache.org/shale/ The feature descriptions have not all been fleshed out yet, but the javadocs are pretty thorough for those cases. I'm not sure what the second question was: about the learning curve? I'm not the one to answer that. But since Shale is a subproject of Struts, there is no shale.apache.org Since there has not been a full release of Shale, the struts-dev list is generally considered the more fruitful place for discussions about it.

RE: Tomcat 5.5.9 with Struts 1.2.7 - ClassCastException - looks like a Tomcat bug
Thank you Christian - you are correct. A colleague also referred me to: http://www.systemmobile.com/wp/?p=152 I had a copy of jsp-api.jar in my app (/WEB-INF/lib/jsp-api.jar) And Tomcat (both 5.0.28 and 5.5.9) has a copy under $CATALINA_HOME/common/lib/jsp-api.jar This makes the copy in my app redundant and it can safely be removed. By removing it, it resolves the ClassCastException with org.apache.struts.taglib.html.MessagesTei But why should this double presence of jsp-api.jar be a problem for Tomcat 5.5.9 but not for 5.0.28?

RE: Question on log on with SecurityFilter and JDBCRealm
Have you considered using a Filter to put the extra stuff in your
Session? We use an initialization Filter that looks up a User record
based on the authenticated user id. We then place that User object both
in the Session and a thread local variable so that it is available to
all the layers of our framework. Our DAO classes use the thread local
variable to set things like Last Updated By. If you use the thread
local variable make sure the last thing the Filter does is to set it to
null so that the thread is not returned to the container's thread pool
with the User object.
public void doFilter( final ServletRequest servletRequest,
final ServletResponse servletResponse,
final FilterChain filterChain )
throws IOException, ServletException
{
if ( servletRequest instanceof HttpServletRequest )
{
final HttpServletRequest httpServletRequest =
(HttpServletRequest) servletRequest;
final String remoteUser =
httpServletRequest.getRemoteUser();
if ( DataHelper.empty( remoteUser ) ||
null.equalsIgnoreCase( remoteUser ) )
{
if ( log.isDebugEnabled() )
{
log.debug( No User info Available );
} //end if
ThreadContext.setUser( null );

My second question is concernig accessing the username value from the
session context.
How is that stored in the session? How can I access it?
My login.jsp form uses standard j_security_check for the action on the
login form, j_username, j_password for the 2 inputs.
I would like, after the login is succesful to forward that to an action
in order to access the database using the username as a key and return
an userID number that I also want to store in the session. How can I
accomplish this?
Thanks in advance,
C.F.

Re: [OT] Loading data for view
Sometimes the simplest answer is the best... and even when it isn't the best, it's *still* simple :) ... How about just creating a new DAO/DTO that only contains the data you need? It would be a duplication to a degree, but that's not *always* an absolutely evil thing... especially since it sounds like the new A object you want to display on the page may not truly model a real domain object (where they others I presume are) but is instead something of a hybrid, I could personally live with this. Either that, or I would just create a single Miscellaneous DAO that has methods that don't *quite* fit in other DAOs... maybe this is one of them... then you would still have a DTO for this particular case, and a new one for each particular case in the DAO, if any more came up. FYI, most of my apps have the true DAO/DTOs, but they all also have such a miscellaneous class for handling things exactly like this. There tend to be very few such cases, but they do come up, and I find this to be a nice way to organize them. In fact, in a couple of cases I've decided to make the DTOs inner classes of the DAO, just to make it obvious they are related and probably limited in their use cases. -- Frank W.

Struts and Laszlo
Hia guys... I´would it be a nosense to integrate Laszlo with struts??? I think Laszlo is responsible for controlling the application, so, may be we can hav struts incharge of generating data in XML format so that Laszlo presentation server show it??? I´m thinking of extending struts so that its output be XML for laszlo (or who ever), abstracting it form HTML... am I making a mountain from a stone ... I mean, a servlet would be enough???

Greetings, I have sent this post more almost 2 days ago without one response. I hope it was simply lost with other posts but still worthy of attention. Here is the original post: I am unable to find a solution... even after searching... and waiting for the espresso to kick in. I have messages and would like to determine the number of messages in the bean. If there is more than one message format the output as a list or else just display the message. Unable to come up with something. This is what I am currently using: logic:messagesPresent message=true tr td colspan=5 class=informationalMessage html-el:messages id=message message=true bean: write name=message filter=false/br /html-el:messages /td td/td /tr tr td colspan=6 height=5/td /tr /logic:messagesPresent Any ideas would be greatly appreciated ! - Glenn
RE: [OT] Loading data for view
If you are thinking about using a single query and bypassing your DTO's then consider using the Data Transfer RowSet pattern; it can be a useful pattern for easily transferring data from a DAO to a view component. If it's disadvantages (clients need to know something about the database metadata, it ignores the domain model) are not relevant in your situation or if they can be minimised (allow its use for read only display or closely controlled use cases only) then it might work for you. BeanUtils provides a neat wrapper for the disconnected recordsets used in this pattern: org.apache.commons.beanutils.RowSetDynaClass. -Original Message- From: Tom Ziemer [mailto:[EMAIL PROTECTED] Sent: 18 August 2005 13:01 To: Struts Users Mailing List Subject: [OT] Loading data for view Hi everybody!

could u please tell me how to Make the ActionMessages work with
Multiple Struts Config file
If you use key when defining a message resources file, then you
must use the same value in the bundle attribute when using JSP tags
which are meant to retrieve messages. As in:
html:messages bundle=master id=msg${msg}/html:messages
I've never needed to use more than one message-resources element in a
project, so I haven't spent much time using these features, but
that's how it works. If you are not specifying a bundle in
html:messages or html:errors then Struts will look for a
message-resources which was configured without any key attribute.

Struts with XSLT
Hi folks, This isn't your usual How do I do X? type question so get ready. Hopefully it will fuel a good discussion. I'm fairly new to struts but have a solid grasp of Model 2 design ideas. The problem, I suppose, is that I am a lone developer (for my own company) which makes it hard to get the balanced view of the technology arena that is aquired through working with other developers. Therefore I have a couple of high level architecture questions that I am interested to hear your views on. The current application that I am working on uses XSLT to generate web pages. As you wold expect a bunch of beans (and some other objects) get converted into XML, run against a stylesheet and out pops a page. This is fine and the application uses a good dose of Model 2 goodness so it's easy to manage and extend. Unfortunately, it has been developed with it's own MVC framework. I would like to convert it to use Struts but I don't want to throw away the flexibility given by using XSLT. Whoa. Before you all shout But Struts can use any technology for the view look at stxx I have had a look at it and stxx has the smell of death around it. As far as I can tell it has been abandoned and doesn't support Struts 1.2.x (the front page hasn't been updated in well over a year). Further more it is fairly obvious that Struts was designed with JSP in mind and while it may work with XSLT my experience of other technologies is that this type of usage with not be easy or pleasant. You are probably wondering by now why I even want to use XSLT rather than JSP. The reason is simple. XSLT provides a huge amount of flexibility and the cleanest separation of the view that I have found. I admit that it is a little more work to create a stylesheet rather than a JSP but I feel that is worth it. I'm not 100% dead set on using XSLT. I have learnt that it is generally not a good idea to go against the grain and if the arguments are compelling enough I will switch to JSP. The problem I have with JSP is that with every release it feels like it gets closer to XSLT. A site I recently developed using JSF + JSP 2.0 (jspx) felt like the pages were nothing more than dumbed down stylesheets. My other concern is that Struts 2.x seems to be heading towards total integration with JSF. While I love the simplicity of JSF and the speed with which one can create a web application it is unsuitable for use on an ecommerce site where the users are expected to be able to bookmark pages (using a refresh is a poor hack IMHO) and, more importantly, robots can't navigate JSF sites. A combination of technologies could be used but that then multiplies the cost of development and maintenance. Finally then the questions. * Should I just stop fighting city hall and abandon XSLT in favour of JSP? * Perhaps it's still a little early to say exactly how Struts 2.x will turn out but will the idea of view technology independence be maintained? * If Struts 2.x doesn't (essentiall) force us to use something akin to JSF will XSLT still be a viable option?

Re: [OT] Loading data for view
Thanks for your answers. I added a new method to my DAO that allows me to execute predefined queries and returns kind of general-purpose-dtos, that only consist of a treemap which stores the requested values from the db. So I get one g-p-DTO per row in my ResultSet that can be passed to the view for rendering. Is this a bad design? Is the Transfer RowSet pattern suggested by Colm a cleaner approach? I am wondering whether this is not a common problem for any application that is based on database with a hierarchical design.

Struts is great for the controller model it provides. If you develop a Laszlo application, Laszlo will probably take the role of the controller (at least that's how I would do it).

Of course there isn't a Struts 2.0, yet anyways, but Struts Shale is already exploring an alternate view, HTML templates, for JSF and JSF itself is designed to be view independent, however, I haven't heard of any view handlers that use XSLT yet. I certainly couldn't call myself a JSF expert but I have, I believe, had enough experience of it to realise that the intended goal writing one page and using alternative renders for different devices doesn't really work. While it's great that you can, in theory, install other renders for the JSF tags it rapidly becomes almost impossible to maintain. I can't believe, for instance, that it would be possible to develop a page that would look good in both a standard browser and a mobile phone. This is at the heart of my interest in XSLT. It removes the whole plug-in render mess that JSF seems to have got itself into. On the flip side the reason I am interested in using JSPs is that I only need to develop for fully featured browsers.

Need help using tiles taglib with JSTL
I'm trying to use the tiles taglib with JSTL (servlet spec 2.4).. if I use
just the HTML tags they work file, and JSTL 1.1 by itself works fine. The
problem comes when I need to use them together. Here I have a list of
inscriptions in the request scope and I want to loop through them and pass
each one to a tile to display each one (individually). I can't figure out
the way to call the tiles:useAttribute tag:
c:forEach items=${listeInscriptions.inscriptions} var=inscription
tiles:insert name=web-inscription flush=true
tiles:useAttribute id=${inscription}
classname=fr.data.Inscription
name=inscription
scope=request
ignore=false/
/tiles:insert
/c:forEach
I'd be grateful for a bit of help with this. I've tried asking about
mixing struts tags JSTL in the past week but haven't had a concrete
example like this and now I'm really stuck. :)

RE: [OT] Loading data for view
Sounds like you're using a data transfer (tree)map pattern, this is largely similar to the rowset version except for the following: * You have to copy values from the underlying data access solution into the TreeMap * Your view component needs to know about the contract for attribute keys in the map (or perhaps not, perhaps this is why you are using a TreeMap) In the rowset version you would wrap a disconnected recordset along with some meta data then use this meta data in your view component e.g. iterate over the metadata to output column headers for your table, then iterate over the data rows to output your data rows. Which is better? No cut and dried answer but here are the pros and cons for both so that you can decide. Rowset Approach --- Pros: * Common interface for all general purpose, read only query operations * Enables you to write generic table display code by using taglibs to iterate over the rowset/map * Responds well to change - the absence of a data translation layer coupled with the use of generic table display code leaves you view indifferent to changes in the underlying data set Cons: * Clients need to know the name of database table columns * Bypasses the domain model, breaks some rules about separation of responsibilities (this shouldn't be a showstopper if it is used in carefully controlled situations such as displaying read only data in a tabular manner) * Loss of type safety (no compile time checking) Map Approach Pros: * Minimises the data translation layer (assuming you can generically translate a record set into a map) * Enables you to write generic table display code by using taglibs to iterate over the rowset/map (assuming you can make assumptions about the order in which the map entries are stored) * Responds well to change - although not as well as the rowset version Cons: * Clients need to know about the contract governing the naming of the map keys * Loss of type safety (no compile time checking) * You'll need to wrap primitives and most access will require casting -Original Message- From: Tom Ziemer [mailto:[EMAIL PROTECTED] Sent: 18 August 2005 15:52 To: Struts Users Mailing List Subject: Re: [OT] Loading data for view Thanks for your answers.

Re: [OT] Loading data for view
Thank you, for your very elaborate answer. After reading your post, it seems that there is really no big difference between the two approaches, so I guess I'll stick with what I've already implemented. I guess losing type safety is not a big issue, since I'll only use my special DTOs for display purposes and thus all values are casted to stings anyway. So could we summarize this thread by saying, use DTOs only when all relationships are required and stick to custom queries when it comes to displaying data, or is this view to simplistic? Are there any common guidelines that help you decide, which approach to apply in a given situation?

You are probably wondering by now why I even want to use XSLT rather than JSP. The reason is simple. XSLT provides a huge amount of flexibility and the cleanest separation of the view that I have found. I admit that it is a little more work to create a stylesheet rather than a JSP but I feel that is worth it. I'm not 100% dead set on using XSLT. I have learnt that it is generally not a good idea to go against the grain and if the arguments are compelling enough I will switch to JSP. The problem I have with JSP is that with every release it feels like it gets closer to XSLT. A site I recently developed using JSF + JSP 2.0 (jspx) felt like the pages were nothing more than dumbed down stylesheets. My other concern is that Struts 2.x seems to be heading towards total integration with JSF. While I love the simplicity of JSF and the speed with which one can create a web application it is unsuitable for use on an ecommerce site where the users are expected to be able to bookmark pages (using a refresh is a poor hack IMHO) and, more importantly, robots can't navigate JSF sites. A combination of technologies could be used but that then multiplies the cost of development and maintenance. Finally then the questions. * Should I just stop fighting city hall and abandon XSLT in favour of JSP? * Perhaps it's still a little early to say exactly how Struts 2.x will turn out but will the idea of view technology independence be maintained? * If Struts 2.x doesn't (essentiall) force us to use something akin to JSF will XSLT still be a viable option?

Re: Best way to store config variables
Have you considered Spring and it's IOC framework? Works wonderfully with Struts (even has a lovely plug-in to get the whole thing working together). The configuration is only one aspect of the whole Spring framework. I was reading about Sprint but I was unable to catch what the Spring really is. I have found tutorials but there was only presented some features, no methodology like in Struts tutorials. I must sit and read about it more. Configuration using some framework sounds very interesting. Could you give me some links where I could see how to handle configuration using Spring?

How can I refer a control in javascript which hava a . in its name
Hi everyone:
Here is my jsp:
html:form
...
html:select ... onChange=change(this)
...
/html:select
html:text name=myForm
property=myobject.subobject .../
/html:form
If user change the selection in the select, I would
like to change the content of the text. Thus, I
write my change() function in javascript:
script language=javascript
function change(select){
document.form[0].myobject.subobject =
select.options[select.selectedIndex];
}
But looks like this does not work. The problem is the
name of the text. In the html it is
myobject.subobject. But seems that javascript does
not take that
How can I refer the text in javascript?

Re: Struts with XSLT

Hopefully it will fuel a good discussion. I'm fairly new to struts but have a solid grasp of Model 2 design ideas. The problem, I suppose, is that I am a lone developer (for my own company) which makes it hard to get the balanced view of the technology arena that is aquired through working with other developers. Therefore I have a couple of high level architecture questions that I am interested to hear your views on. The current application that I am working on uses XSLT to generate web pages. As you wold expect a bunch of beans (and some other objects) get converted into XML, run against a stylesheet and out pops a page. This is fine and the application uses a good dose of Model 2 goodness so it's easy to manage and extend. Unfortunately, it has been developed with it's own MVC framework. I would like to convert it to use Struts but I don't want to throw away the flexibility given by using XSLT. Whoa.

Well yes, browser will create DOM based on HTML received, but you do not alter DOM *directly* from server. Oh, you did not mean browser DOM? You meant to return XML containg app data from server-side DOM? Then how does that correlate with your dismissal of client-side XSLT processing? Also, try StAX. I have not run any perfomance tests myself, but they say it is faster than SAX. At least, not slower. And is easier to use.

Testing Struts With JUnit
I´m trying to test the action below :
public class FamiliaDNCAction extends BasicAction {
public ActionForward unspecified(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest request, HttpServletResponse response) throws
BusinessException {
Set msgs = new HashSet();
return loadPage(actionMapping,actionForm,request,response);
}
public ActionForward loadPage(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest request, HttpServletResponse response) throws
BusinessException {

FamiliaDNCForm form = (FamiliaDNCForm) actionForm;
List dados = cad.findByCodigoDependencia(form.getCodDependencia().intValue());
session.setAttribute(dadosdnc,dados);
return actionMapping.findForward(inicial);
}
}
The parameters for the action are
FamiliaDNC.do -- calls the class
ev -- the parameter for the method, when not set calls unspecified method
public class TestFamiliaDNCAction extends MockStrutsTestCase{
FamiliaDNCAction fdnca;
public TestFamiliaDNCAction(String nomeDoTeste) {
super(nomeDoTeste);
}
public void setUp() throws Exception {
super.setUp();
fdnca = new FamiliaDNCAction();
}
public void testLoadPage() {
addRequestParameter(codDependencia,1);
addRequestParameter(codTipoFamiliaInsumo,0);
addRequestParameter(ev,unspecified);
setRequestPathInfo(/corporativo/cadastro/cadFamiliaDNC);
actionPerform();
verifyForward(inicial);
verifyForwardPath(/corporativo/cadastro/corp_cad_familia_dnc.jsp);
verifyNoActionErrors();
}
I´m getting nullPointerException, when i try to test it. I´m not sure
witch parameters i add to the request for example in the action form i have:
form name=form2 method=post action=./cadFamiliaDNC.do
input type=hidden name=codFamiliaDNC value=
input type=hidden name=codTipoFamiliaInsumo
input type=hidden name=codDependencia
.
/form
My question is, witch parameters do i put in the addRequestParameter(?,?); ?
any clue ?
Thanks in advance

How can I refer a control in javascript which hava a . in its name
Hi everyone:
Here is my jsp:
html:form
...
html:select ... onChange=change(this)
...
/html:select
html:text name=myForm
property=myobject.subobject .../
/html:form
If user change the selection in the select, I would
like to change the content of the text. Thus, I
write my change() function in javascript:
script language=javascript
function change(select){
document.form[0].myobject.subobject =
select.options[select.selectedIndex];
}
But looks like this does not work. The problem is the
name of the text. In the html it is
myobject.subobject. But seems that javascript does
not take that
How can I refer the text in javascript?

What i ment with DOM, was not writing xml somehow, but leting your business logic return dom-objects instead of whatever-we-might-call-it normal java objects. On the other hand, it would mean transmitting overhead on the net between webserver and business logic. But if you use an XML DB on the other hand...

Hopefully it will fuel a good discussion. I'm fairly new to struts but have a solid grasp of Model 2 design ideas. The problem, I suppose, is that I am a lone developer (for my own company) which makes it hard to get the balanced view of the technology arena that is aquired through working with other developers. Therefore I have a couple of high level architecture questions that I am interested to hear your views on. The current application that I am working on uses XSLT to generate web pages. As you wold expect a bunch of beans (and some other objects) get converted into XML, run against a stylesheet and out pops a page. This is fine and the application uses a good dose of Model 2 goodness so it's easy to manage and extend. Unfortunately, it has been developed with it's own MVC framework. I would like to convert it to use Struts but I don't want to throw away the flexibility given by using XSLT. Whoa. Before you all shout But Struts can use any technology for the view look at stxx I have had a look at it and stxx has the smell of death around it. As far as I can tell it has been abandoned and doesn't support Struts 1.2.x (the front page hasn't been updated in well over a year). Further more it is fairly obvious that Struts was designed with JSP in mind and while it may work with XSLT my experience of other technologies is that this type of usage with not be easy or pleasant. You are probably wondering by now why I even want to use XSLT rather than JSP. The reason is simple. XSLT provides a huge amount of flexibility and the cleanest separation of the view that I have found. I admit that it is a little more work to create a stylesheet rather than a JSP but I feel that is worth it. I'm not 100% dead set on using XSLT. I have learnt that it is generally not a good idea to go against the grain and if the arguments are compelling enough I will switch to JSP. The problem I have with JSP is that with every release it feels like it gets closer to XSLT. A site I recently developed using JSF + JSP 2.0 (jspx) felt like the pages were nothing more than dumbed down stylesheets. My other concern is that Struts 2.x seems to be heading towards total integration with JSF. While I love the simplicity of JSF and the speed with which one can create a web application it is unsuitable for use on an ecommerce site where the users are expected to be able to bookmark pages (using a refresh is a poor hack IMHO) and, more importantly, robots can't navigate JSF sites. A combination of technologies could be used but that then multiplies the cost of development and maintenance. Finally then the questions. * Should I just stop fighting city hall and abandon XSLT in favour
RE: Struts with XSLT
Hi All, Seems a bit of the silver bullet scenario is going in the discussion of XSLT versus Struts approach, someone has correctly said there's no silver bullet. You are required to use your judgement based on your experience on which tool/technique to use for what situation for optimal results. Again I don't claim to know all but here' my 2 cents on some of these off the top of my head:- XML/XSLT Pros i. Multiple rendering formats for multiple channels/devices. HTML/WML/... Cons i. Usually very slow for complex page with lot of transformations Struts Pros - a. Cleaning up very complex navigations into more manageable and maintainable structure. Cons a. It's in bed with JSP rendering, and lot of the add-ons can't be utilized generically such as in the case of XMS/XSLT Again technologies tend to evolve over time, just like Servlets was the thing to do when all you had was CGI, and Struts improvised on Servlets to make the hard wiring and navigation of the controller servlet into more managable XML configuration. And now there's JSF/Shales/Spring Framework and God knows what else... so take your pick and mix and match for best results! There no silver bullet is what I'll still say... with time everything changes.

Re: Struts and Laszlo
Luc, I have designed Laszlo applications having both PHP and Servlets as controllers. It worked great and your idea is right on. In fact I am starting a Struts/Laszlo app pretty soon. Have in mind that Laszlo is the View of the MVC model. I understand that you can also use Laszlo as the controler. But I had a project done for School with laszlo and Servlets and the way I've used Laszlo was to act as the view model and do browser validation as you can have Javascript with Laszlo. Other than that all the logic and interaction with the business layer were done by my servlets. With Struts the principle is the same. Keep in mind one thing for Laszlo. Even if you only post data to your Struts action you have to return some sort of xml structure or your Laszlo app will crash. Something like: result statussuccess/status /result or result status=success/ Basicaly instead of having a JSP front end you will have a Laszlo front end. However programming it with Laszlo is more like doing a GUI app with events and all other than a CGI application. good luck Luc Lucas Bern wrote: Hia guys... I´would it be a nosense to integrate Laszlo with struts???

Re: Question on log on with SecurityFilter and JDBCRealm
Steven,
Thanks!
Yeah, great idea. In fact I was reading about that on O'Reilly's Struts
Cookbook.
I have one question to you though:
How is the filter executed? After the login? Or after every http request
to the server?
What does fire the filter up? Is it like an event for a GUI app? I would
like to understand this
concept better.

Subject: Question on log on with SecurityFilter and JDBCRealm
Hello all,
I've managed to have successful authentication with securityFilter and
JDBCRealm.
I have a few questions that I was hoping you could clarify for me.
After the login is successful, is there any way to forward that to a
success page/action
so that I can add extra stuff to the session context? This is my
login-config session
in the securityfilter-config.xml file:
*login-config*
*auth-method*FORM*/auth-method*
*form-login-config*
*form-login-page*/login.jsp*/form-login-page*
*form-error-page*/error.jsp*/form-error-page*
*form-default-page*/index.html*/form-default-page*
*/form-login-config*
*/login-config*
My second question is concernig accessing the username value from the
session context.
How is that stored in the session? How can I access it?
My login.jsp form uses standard j_security_check for the action on the
login form, j_username, j_password for the 2 inputs.
I would like, after the login is succesful to forward that to an action
in order to access the database using the username as a key and return
an userID number that I also want to store in the session. How can I
accomplish this?
Thanks in advance,
C.F.

Resizing output image from a Struts Action
Hello all, I have an action to retrieve an image from a database BLOB field and display it. It works great. However I wanted to resize the image proportionaly. Hence I think on writing a second action, that would call the first in order to retrieve the image. Then, would work on this image to resize it and send it over to the browser. Or maybe change the original action to do that to save the overhead. I would like to know how to accomplish image resizing in Java. The image can be a JPG, a GIF or a BMP. Hence I need to handle all these situations depending on the Content/Type that is stored in the database along with the BLOB. When you retrieve a BLOB you write it to a ByteArrayOutputStream. Then you just set the response.SetContentType , setContentLength and send the ByteArrayOutputStream by calling the method .toByteArray() and .flush. I have two options, I can change the original Action to accept a request attribute to determine the width or height. Then I can work the image and spit it out. The way I think about it is that I would need to, somehow, create an Image object by taking the ByteArray from the ByteArrayOutputStream. This image object could be a JPG, GIF or BMP. I would determine which one to use based on the Content/Type of the database. They this object could be resized and return a byteArray that I could send to the browser. I guess I have most of it done but I would like advise on how to: 1) Construct a JPG, GIF or BMP object with the ByteArray 2) Resize this object and produce a resided ByteArray so that I can send it to the browser. Any ideas on how to perform that? Any documentation regarding this that I could browse? Thanks, C.F. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Using custom tags and struts together
Hello all Has anybody successfully used Stuts tags and Custom tags together? For example: Consider a custom tag with the following code: out.println(html:link action=\Update.do\ + entry[ix] + /html:link); The custom tag appears to write the output directly to the socket without further Struts tag evaluation, consequently the HTML source on the browser includes html:link which it doesn't understand. 1. How about writing the link using a href=/WEB-INF/pages/update.jsp/a When I do this I lose the connection to my current session. Not a solution. 2. Try return true in the theBodyShouldBeEvaluatedAgain method. I tried this and the code got into a loop (I believe this simply recurses back through my code). If I am supposed to use this somebody will need to tell me a simple way of stopping the recursion. 3. The only other alternative I have is to look into the Struts source code and try and find some internal method to call to evaluate the generated code before I print it to the socket. Hope somebody has tried to do this before... Kind regards mc FOCUS Computing Mob: 0415 24 26 24 [EMAIL PROTECTED] http://www.focus-computing.com -- No virus found in this outgoing message.

Re: Struts with XSLT
We have been using stxx for a while now, mostly for output transformations only and it work perfectly. I would recommend you to consider it, and I have no stock in stxx ;-) ! Apart from this, we quite often use inline XSL transformations provided by JSTL nowadays not as flexible, but certainly useful in 'hybrid' designs. Complex form stuff, and pages which need to be update oftern are mostly taken care of by jsp2.0 pages seems that our designers prefer jsp2.0 over the (for them) more complex XSLT. regards, Peter On Thu, 2005-08-18 at 16:31 +0100, Graham Smith wrote: On Thursday 18 August 2005 16:02, Don Brown wrote: Hmm...smell of death for stxx might be a bit harsh :) Yeah ok, it was a bit harsh - sorry.

Of course there isn't a Struts 2.0, yet anyways, but Struts Shale is already exploring an alternate view, HTML templates, for JSF and JSF itself is designed to be view independent, however, I haven't heard of any view handlers that use XSLT yet. I certainly couldn't call myself a JSF expert but I have, I believe, had enough experience of it to realise that the intended goal writing one page and using alternative renders for different devices doesn't really work. While it's great that you can, in theory, install other renders for the JSF tags it rapidly becomes almost impossible to maintain. I can't believe, for instance, that it would be possible to develop a page that would look good in both a standard browser and a mobile phone. This is at the heart of my interest in XSLT. It removes the whole plug-in render mess that JSF seems to have got itself into. On the flip side the reason I am interested in using JSPs is that I only need to develop for fully featured browsers. Thanks for the feedback, Graham Another project we are working on in the sandbox, Struts Ti, already has support for XSLT. Hope that helps, Don * If Struts 2.x doesn't (essentiall) force us to use something akin to JSF will XSLT still be a viable option? Thanks for reading this far. I really look forward to hearing your views.
