[OT] JSTL : test the first char of a String
Hello, I'm using JSTL and Struts-EL. I would like to test the first char of a String. The string is a URL, and can be a path to some action on my webapp or any external URL. I'd like to test if the url starts with '/' to select the html:link attriibute to use : page or href. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [OT] JSTL : test the first char of a String
I've found this way :
c:if test=${link.bytes[0] eq '/'.bytes[0]}
Not so pretty, but working !

adding items to list in a tile definition using extension
Hello, Is it possible when extending a tile definition to ADD some items to an existing list (defined by parent tile definition) ? I would like to do this : My web pages have a top line that describe flow in app, something like this : home catalog search result I'm using a tile definition for this using the putlist and item tags. But I need to set the full list on every definition. I would like to use definition extends mecanism to have a home tile definition, extend it in a home.catalog, itself extended by a home.catalog.search and so on. Every tile definition should only have to ADD it's item to the existing list. Is they're a way to do it ? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: adding items to list in a tile definition using extension
OK, I've done it another way :
I put ALL items used in the webapp in a list :
definition name=tile:base
putList name=locations
item vale=home
item vale=catalog
...
and I extend it for every page :
definition name=tile:search-result extends=tile:base
put name=currentLocation value=0.1.2/
/definition
I use c:forTokens to get indexes in locations (0, 1 2) from
currentLocation and print ${locations[index].value} in the JSP.

no, not with the current tiles implementation

suppose you should use another tiles:putList for each of the following
extensions and treat the values of them like they were in just one list.
but its evil! should be already in tiles ;)
also you have to decide if want to be able to override old items (then you
just have to implement it)
i.e. (without markup :)
definition name=justOne
putList name=bla1
item name=itemX value=valueX
...
definition name=alreadyTwo extends=justOne
putList name=bla2
item name=itemY value=valueY
...
when using it search for blaN until you don't find that blaN anymor (using
logic:iterate and logic:exists and/or EL syntax)

Re: Using ExpressionEvaluatorManager in Struts Action execute() method
Not beeing in a real JSP (your servlet doesn't extend any JspServlet) may cause some troubles to your servlet container. To evaluate EL expression, you should consider using Jelly and Jexl language from jakarta-commons. I did it with success. Nico. f. a écrit : Hi, I am currently developping custom tags library for my company. We use ExpressionEvaluatorManager in our custom tags. That works really fine. But one of our action class will be called from cells in a table of data (Html DataTable). The Web Developper should be able to specify what to put in the session under a given name when this kind of link is clicked. And the way to do that is an expression in Expression Language (JSTL). So my Struts Action code should be able to evaluate the (request Parameter) expression in the Action execute() method to be able to put the right object in session before next forward. I got the Page context with: PageContext pc = javax.servlet.jsp.JspFactory.getDefaultFactory().getPageContext( this.getServlet(),request, response, null, true, 4096 , false ); I evaluated the expression evaluatedDetailRef = ExpressionEvaluatorManager.evaluate(null, detailRef, Object.class, pc); I released the Page Context javax.servlet.jsp.JspFactory.getDefaultFactory().releasePageContext(pc); And now my servlet container (Jetty) seems crazy and instead of processing JSP file and sending result to browser, it sends JSP source directly to browser Does it make sense for you ? Is it crazy to use EL in Action execute( ) method ?? (Was an idea of my Team leader ) I am stuck. Thanks for your help.

Re: [OT] RE: web.xml DTD for Servlet 2.3 Struts 1.1
Assuming this resources are right : http://www.searchwin.net/doctype.htm http://www.blooberry.com/indexdot/html/tagpages/d/doctype.htm .. I thing the last (optional) part of a DOCTYPE declaration has to be a valid URL to the referenced DTD. Perhaps I'm wrong, because I didn't found a normative document about this. Actualy, XML parsers are using this URL to look the Internet for a DTD when they don't have a local one for the PUBLIC identifier found in the document. Nico. Wendy Smoak a écrit : A long time ago, Craig McClanahan wrote: It is a common misconception that the public identifiers of a DTD like this *must* actually be working URLs [...]. They are just unique strings of characters that (often) happen to look like URLs. Blame the XML community for that :-). And then Yuan Saul asked: If a local copy of DTD is not available, then an Internet connection is required, in this case, does the URI has to be pointing to a working URL where the DTD file can be retrieved? Which is also my question, but there is no reply in the archives. Anyone? Today we got a note from campus IT saying that they believed some problems in their J2EE apps were related to code that connects to http://java.sun.com behind-the-scenes to download various DTD files related to parsing XML documents. In addition to whether it happens at all (going out to the internet to retrieve the DTD) I'm also curious if it's the XML parser, or the Servlet container, etc. What component would make the call out to get the DTD? I've always wondered... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Question about DTDs ...
DOCTYPE syntax uses an optional URI for the DTD, so that a validating XML parser can download an unknown DTD and validate the document. Struts registers local copy of it's configuration DTD to the XML parser (struts, tiles validator). This way they're is no need to have access to the Internet Nico. Alain Van Vyve a écrit : A lot of things have to be parsed : web.xml, struts-config.xml and so on so for example, lines like that are already present in our XML files : !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.2//EN http://java.sun.com/j2ee/dtds/web-app_2_2.dtd; or !DOCTYPE struts-config PUBLIC -//Apache Software Foundation//DTD Struts Configuration 1.1//EN http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd; I understand the concept of DTD but does it mean that each time a XML file is parsed, a connection to SUN or Jakarta is established in order to retrieve the DTD ?

If you're using a servlet 2.3 container (most recent servers) you doesn't need to configure taglibs in web.xml, they're automatically searched by container in your webapp jars.

Re: White space problem
You can use the string:trim tag from jakarta taglibs Nico. Hi all I am using struts with jstl. I have a problem that is a bit annoying. In the navigation jsp on one of my sites I have 2 nested c:forEach tags that have c:if tags inside them. If a bean element meets the c:if condition it gets c:out to the page, if not the loop skips over it until all the outer c:forEach beans have been looped. The problem is however when the c:if condition is not met a white line is written out by the c:forEach (ie one white line for each iteration regardless of the c:if condition). This ends up with a MASS of white space on the page. Is there anyway to stop the c:forEach writing out the white space ? tia Chris *** This e-mail and its attachments are confidential and are intended for the above named recipient only.

Re: Problem with huge session memory and ActionForm
ActionForm has this attribute : protected transient ActionServlet servlet All ActionForms share the same ActionServlet instance. As this attribute is transient, it will not be serialized if form is put in session (and session itself is serialized). So I think the session size is not well computed by JPRobe profiler, as every referenced objet are included in size computation, even if they're shared between objects or declared transient. A better way sould be to run the app without any session created, get JVM memory usage (mem1), then open N user sessions, and get JVM memory usage (mem2). (mem2 - mem1) / N is *real* session size. Nico. Why not change those forms to request scope instead?Where ever feasible I mean.If any data is not shared across pages in a wizard like flow, just put that form in request.This should be applicable to 90% of the cases.

[OT] Classloader troubles
Hi all, I'm posting on Struts list because I know they're is lot's of J2EE experts here. I want to test my webapp on Tomcat, but it depends on some external system. I've got a jar that emulates it. When I package it with the webapp (WEB-INF/lib) it works fine. I would like to test the webapp packaged without this emulator jar. I tried putting it in $TOMCAT/common/lib. I get a ClassCastException. I think it comes from this : webapp requires the external API, let's say a class named ExternalSystem. It is configured to search for an implementation class named ExternalSystemMockImpl (using reflexion API). Webapp classloader doesn't find it, and delegate class searh to it's parent classloader (tomcat ones). Parent classloader finds the class from my emulator jar, run it and return some MockResult object, that implements ExternalResult from the external API Calling webapp tries to cast resulting object to ExternalResult, class that is visible to webapp classloader. Then my code is doing : ExternalResult result = (ExternalResult) obj; where obj is my MockResult instance, that implements ExternalResult from parent-Classloader, and casting it to a webapp-Classloader ExternalResult fails ! How can I solve this ClasLoader conflict ? Nico. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [OT] Classloader troubles
the webapp hasn't trouble to load ExternalSystemMockImpl. It uses reflexion to do it from some configuration data that is use to set implementation (production | mock). The problem is that the resulting object has to be casted to an interface from the API : IExternalSystem: (1)Class clazz = Class.forName(className); (2)return (IExternalSystem) clazz.newInstance(); from webapp, I think IExternalSystem is loaded by webapp ClassLoader. As ExternalSystemMockImpl is loaded from tomcat commons ClassLoader, it doesn implements the IExternalSystem loaded by this commons-ClassLoader, that cannot be casted in IExternalSystem loaded by webapp-ClassLoader. I get a ClassCastException on line 2. Nico. If ExternalSystemMockImpl is contained in a JAR file that's in $CATALINA_HOME/common/lib, I don't see why the app wouldn't be able to load it. For example, I've got a JAR file for the Oracle JDBC driver in common/lib and I can do the following just fine in a JSP: % ClassLoader cl = getClass().getClassLoader(); Class clazz = cl.loadClass(oracle.jdbc.OracleDriver); Object obj = clazz.newInstance(); % If there's code in the external JAR file that needs to make use of a class loader, it should probably use the result of Thread.currentThread().getContextClassLoader(). Can you provide a little more detail on how the app is using reflection to locate ExternalSystemMockImpl?

I get a ClassCastException on line 2. Nico. If ExternalSystemMockImpl is contained in a JAR file that's in $CATALINA_HOME/common/lib, I don't see why the app wouldn't be able to load it. For example, I've got a JAR file for the Oracle JDBC driver in common/lib and I can do the following just fine in a JSP: % ClassLoader cl = getClass().getClassLoader(); Class clazz = cl.loadClass(oracle.jdbc.OracleDriver); Object obj = clazz.newInstance(); % If there's code in the external JAR file that needs to make use of a class loader, it should probably use the result of Thread.currentThread().getContextClassLoader(). Can you provide a little more detail on how the app is using reflection to locate ExternalSystemMockImpl? Quoting Nicolas De Loof [EMAIL PROTECTED]: Hi all, I'm posting on Struts list because I know they're is lot's of J2EE experts here. I want to test my webapp on Tomcat, but it depends on some external system. I've got a jar that emulates it. When I package it with the webapp (WEB-INF/lib) it works fine. I would like to test the webapp packaged without this emulator jar. I tried putting it in $TOMCAT/common/lib. I get a ClassCastException. I think it comes from this : webapp requires the external API, let's say a class named ExternalSystem. It is configured to search for an implementation class named ExternalSystemMockImpl (using reflexion API). Webapp classloader doesn't find it, and delegate class searh to it's parent classloader (tomcat ones). Parent classloader finds the class from my emulator jar, run it and return some MockResult object, that implements ExternalResult from the external API Calling webapp tries to cast resulting object to ExternalResult, class that is visible to webapp classloader. Then my code is doing : ExternalResult result = (ExternalResult) obj; where obj is my MockResult instance, that implements ExternalResult from parent-Classloader, and casting it to a webapp-Classloader ExternalResult fails ! How can I solve this ClasLoader conflict ?

Re: Configuring Struts NOT to create (unauthentified) sessions
This is exactly what I'm looking for. For some of the applications I'm working on, my customers are paranoiac about security. I think that if a unauthentified user is able to create a session on the server, it can expose the server to DOS attack, because every created session will use some memory. It is realy simple to write a client that sends hundred of request to the server. If a session is created on each request, server will quickly be out of memory (Session object + stored objects (Locale) size). If a session is created only for authentified users, server will survive such (simple) attack. Perhaps I'm wrong about this, if this scenario is stupid please tell me. For example, I've seen that RequestUtils.retrieveUserLocale() uses request scope if no session exists. This way, no session is created when displaying a login JSP that uses i18n. With locale=true (default) a new session is created when ActionServlet process a request. We need to set it to false to control session creation. I want to know if they're is other Struts properties to set to avoid creating new session for non-authentified user. Nico. Hi Manfred I think Nicolas is trying to find all places where Struts manipulates the session in some way.. Locale=True does indeed manipulate the session..thus resulting in the session being created, if not already there. When no one (action, object, tag, whatever) has requested attributes to be stored in the session, no session object will exist..Session info (cookie, URL rewriting, etc) is only created if there are attributes on the Session object.

Re: Configuring Struts NOT to create (unauthentified) sessions
A session CONTEXT is created when some code uses request.getSession() or request.getSession(true) session tracking (using coockie or URL rewriting) is used keep association between user and contexte. Session tracking mecanism use a random number generator but doesn't use memory to store some data until a CONTEXT is created. Nico. HG. I _don't_ think you are right. A session object exsists with and without struts. The documentation says: -- The Hypertext Transfer Protocol (HTTP) is by design a stateless protocol. To build effective web applications, it is imperative that requests from a particular client be associated with each other. Many strategies for session tracking have evolved over time, but all are difficult or troublesome for the programmer to use directly. This specification defines a simple HttpSession interface that allows a servlet container to use any of several approaches to track a users session without involving the Application Developer in the nuances of any one approach. -- The session is more than the attributes, struts can put into it ;-) Manfred HG wrote: Hi Manfred I think Nicolas is trying to find all places where Struts manipulates the session in some way..

Re: Configuring Struts NOT to create (unauthentified) sessions
I would like to set my login JSP to have this directive (%@ page session=false %) and others ones to be in WEB-INF (not visible to users) I use an application specific authentification. I would like any user (friend or hacker) to get access to the (internationalized) login page, be able commit login form to /login.do, and use struts-validator to validate required inputs. For all this no session should be created. When user is authentified, access to other URIs of the applicaton are granted by a custom processRole. Nico. How are you performing authentication? Depending on the process you're using, it may be possible to avoid hitting any of those conditions until after it's successful. P.S. By default, a JSP will create a session if one doesn't already exist (nothing to do with Struts), so any pages that can be hit by unauthenticated users should do: %@ page session=false % Quoting Nicolas De Loof [EMAIL PROTECTED]: I've made a grep on Struts 1.1 sources.

Re: Custom Link Tag
You have to copy/paste extended taglib description in your custom tld.
You should write a simplest custom tag that includes it's body into response (the way
logic: tags do) on some
application-specific conditions, and use it this way :
myTag:isUserInRole path=/sample.html
html:link href=/sample.htmltest/html:link
/myTag:isUserInRole
Your tag will be reusable for various presentation items.
Nico.
Thanks Nico.
However, I'm facing a problem with using my custom linktag.
I am trying to specify the href attribute from which I shall get the
path by using:
dtag:dlink href=/sample.html showAlways=truetest tag/dtag:dlink
However, my jsp is giving me the error: Error(12): Attribute: href is not a
valid attribute name
I suspect that since it is looking up the tld which I've written, which
doesn't have the href attribute, that's causing the error.
Now, my tag class extends the struts html LinkTag, but how do I get it (my
TLD) to include the attributes of the LinkTag in the original
struts-html.tld.
Thanks.

Hi,
I am writing a custom tag: MyLinkTag that extends the

MyLinkTag has two fields. They are
showAlways : Boolean alternateLink : String.
The functionality of the MyLinkTag is captured in the following code
snippet:

HttpServletRequest request = pageContext.getRequest();
ActionMappings actionMappings =
(ActionMappings)request.getAttribute(Action.MAPPINGS_KEY);
String path = getHref();
ActionMapping actionMapping = actionMappings.findMapping(path);
String[] roleNames = actionMapping.getRoleNames();
boolean userInRole = false;

}
else{
if(showAlways){
setDisabled(true);
}
else{
//don't show the link
return SKIP_BODY;
}
}
}//end if !userInRole
}//end for loop
***
The problem is I don't know where to place this code i.e. in which

What method should I override??
And what should be the return [integer] values??

Re: Problem with BeanUtils.copyProperties()
I think the javabean spec doesn't allow multiple setters for a single property. If I'm right, you cannot have two setXXX method with different parameters types, as beanutils just looks for a method named setXXX without using parameter types. Nico. Ivan De La Pena wrote: Hope this helps : Thanks Ivan, It did help :-). The problem I had was a bit strange: in my business object a had a method setSomeProperty(String[] data) and a method setSomeProperty(Vector data). copyProperties() called setSomeProperty(Vector data) on my business bean although the method signature of the source bean has the first method signature (witch a String[]). If there are multiple methods with the same name, shouldn't copyProperties() pick the one with the same method signature as in the source bean??? In my opinion this would at least be a desirable default behavior Has anybody else experienced this problem?

Re: Custom Link Tag
Place your code in doStartTag as it can return SKIP_BODY to exclude body from
resulting HTML.
return EVAL_BODY_INCLUDE if you want the body to be included

Re: creating a class that extends Action Mapping...what is the purpose of it?
Sometime we need to add some info to struts mappings, and for this we use a class that extends ActionMapping. As an example, we need for a webapp to add a description to any mapping to build some stats. DescActionMapping defines a description attribute. every action-mapping in struts-config sets this property : action-mappings type=DescActionMapping action path=/login name=LoginForm input=error scope=request type=ConnexionAction set-property property=description value=Authentification/ forward name=success path=/accueil.do / forward name=error path=tiles:connexion / /action (...) Nico. Hi, I was trying one struts example. In that example, it has created one class whcih extends ActionMapping class. I was just wondering why we need to create this class and when is it used and whether we define this class in struts-config or web.xml? Regards Deepak Saini _ Contact brides grooms FREE!

[OT] problem with binary ressource when packaged in jar (war)

When used inside the webapp, generated gif is incorect : it has lot's of strange binary errors. When putting the classe and the gif file into a jar, it fails too. I use java 1.4.2 on windows 2000.

best practice to avoid chaining actions
Hi all, I've read on this list that chaining actions is considered as a design error. On the project I'm working on, some developers need to make some business validation on a form before going to the next page. This validation occurs in an Action class, let's say Action1. From business validation point of view, Action1 return success or error. Next page needs some pre-computing to select JSP and display, because of some list of values that are time and user-dependant. From next-page precomputing point of view, forward can be simple-select or multi-select What is the best way : - Action1 validates, Action2 computes datas before page2 display, and we need to chain Action1 and Action2. - Action1 both validates ans computes datas for page2. It doesn't seems to be good as this mix to roles in Action1 and we cannot display page2 without validating. Is they're a good way to do this without some workflow extension ? Thanks for any help or suggestion. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: best practice to avoid chaining actions
Hello, If action chaining is a design error, then the struts-example that comes with struts distributions has a design error, saveSubscription forwards to editRegistration.do! Anyway, what I do is keep validation off action classes, by moving them off to action forms using validator and/or overridden validate() methods. (Business logic validations that need access to the data model must be in the model ofcourse, and not in action classes.) You're right, my description was a little short about this : In Action1, we use business model validation methods to validate some form datas : to know if user is allowed to use some datas he entered for the business process he want's to begin.

Re: best practice to avoid chaining actions
Very interesting thread, Thanks a lot Nico. Hi, There was a long discussion about action chainning some time ago. http://marc.theaimsgroup.com/?l=struts-userm=104427309720653w=2 And as summarized in the above discussion, I think if you are using 2 actions to complete 1 logical function, then it is bad design.And that is what I think the approach suggested by you looks like. To answer you specific question,like already suggested, I will put the validation logic in the form bean(SO that same validation can be used in some other action if it is using same form ) and then put the validation call in the action(Something like form.validate) and forward to error if the validation fails. And if validation succeeds, go ahead with normal data processing(which is data retrieval in this case.)

Re: chained actions
Here is what happens : reset() is called before every form population form population occurs before every struts action url (*.do) is processed. When an action forwards to another one using forward path=another.do, struts actionServlet is called to handle this second URL. FormBean is then reseted and populated from request. If you doesn't use a redirect, request is the same an all parameters are still in it, so formbean is populated the same way for the two actions. If you use a redirect, when first action forwards, a HTTP Redirect response (with location=another.do) is sent to the browser. Browser follows new location and builds a new request, but this new request hasn't any parameter. When form population occurs for another.do, form-bean is reseted and population has no effect (no parameters !).

Subject: why is there no attribute name for html:form in struts???
Hi,
I want to submit a form from a frame, while the button
I click to submit is in another frame. I am able to do
this easily using the following code in Model 1
architecture :
if((parent.frames[frame3].document.forms[roadinfo].name)
== (roadinfo)){
parent.frames[frame3].document.forms[roadinfo].action=http://localhost:8080/examples/jsp/mppp_license/Licenses/road
infoHandler.jsp;
//
parent.frames[frame3].document.forms[roadinfo].target=_blank;
parent.frames[frame3].document.forms[roadinfo].buttonType.value
= buttonType;
parent.frames[frame3].document.forms[roadinfo].submit();
}
}
But, I find that in struts, there is no attribute
called 'name' for form. Then how can I identify the
form which is in the first frame, from the frame in
which the submit button is present?
Please let me know if there is a way to do this in
struts.
Thanks

Re: URGENT: html:options
collection attribute of html:options tag is used to set the name of a bean (in some
scope) that is a collection of the
items off the select-box.
You need to put your Vector into page or request scope to use this tag:

request.setAttribute(items, agencyIds);
%
html:select property=agencyId
html:options collection=agencyIds

Re: URGENT: html:options
jsp:useBean id=agencyIds type=java.util.Vector scope=page /
create a scripting variable agencyIds and a page scope bean agencyIds. This
created vector is empty.
% agencyIds= MyUtils.getAgencyIds(); %
chags the object referenced by the scripting variable, but not the page scoped bean.
You should use something like this, assuming populateAgencyIds(List) adds items to an
existing List :
% MyUtils.populateAgencyIds(agencyIds); %

thanks for the reply.
doesn't the jsp import statement followed by the usebean ie,
%@ page import=MyUtils %
jsp:useBean id=agencyIds type=java.util.Vector /
introduce the agencyIds into page scope.
also with the example you gave me should
html:select property=agencyId
html:options collection=agencyIds
label=label

shouldn't the value of collections be items, since that is the key you used.

Re: JSP Expression inside Struts html:text property
When you want to use Runtime Expression in a JSP tag, the full tag attribute value
must be RTexpression, not just part
of it :
html:text property=%= \person\ + x % value=/
In your case you should think using indexed properties and logic:iterate to display
your datas.

Howdy -
I have some JSP code that looks like this:

of course I was expecting the HTML output to be something like:

input type=text name=person3 value=
input type=text name=person4 value=
input type=text name=person5 value=

input type=text name=person%=x% value=
input type=text name=person%=x% value=
input type=text name=person%=x% value=
input type=text name=person%=x% value=
input type=text name=person%=x% value=
input type=text name=person%=x% value=
input type=text name=person%=x% value=

Re: about initalization
in web.xml, struts controller servlet is set with a load-on-startup value. You can configure another servlet in this file with a load-on-startup value greater that struts'one. This way your servlet will load and configure after struts.

Re: File Upload size restriction ??
I submited a bug on bugzilla for this. I discovered that I get this strange freeze when generated HTML is *long*. As I use the validator, I restricted the generated javascript to the 3 functions we use on the webapp and it works. If I add some hundred of basic HTML at JSP end, if freeze. You should try to limit generated HTML size, until someone founds the problem (no idea for myself, neither reading the code nor using a debugger). Nico. I'm experiencing the EXACT same problem (Win2000, Struts 1.1 RC 1, Weblogic 7, Sun JDK 1.3.1_07). I've noticed that if my input forward is a simple JSP, it works fine. Also, it works fine if the input forward is a tile definition which simply specifies a JSP, like this: definition name=tile.struts.upload.upload path=/upload.jsp/ However, it hangs if I try to get fancy and use some inheritance in my definitions, like this: definition name=tile.struts.upload.upload extends=tile.main put name=window.title.key value=key.title.window.home/ put name=body.tile value=tile.struts.upload.upload.body/ /definition definition name=tile.struts.upload.upload.body extends=tile.main.body.internalTitle put name=title.key/ put name=content.tile value=/upload.jsp/ /definition It does eventually come back with the error message, but only after 5 - 10 minutes (and I see the second request just like Nico mentioned). If I switch to JRockit 1.3.1, it hangs forever (well, at least as long as lunch :-) Nicolas, have you or anyone else discovered a solution/workaround? Thanks! best, garthabrindoid Nicolas De Loof wrote: That's what I was trying to do and discovered that upload behaviour changes when going over Struts configured file-size limit (4Mo in my case).

I am using tomcat+jboss as application server.I have setup several tomcat_jboss instances in a cluster environment and of course I use struts in my application.HttpSession created in one instance will get replicated across all members in the cluster.It's just what I want.The problem is how should I connect the app servers with the backend db server(s)?

Re: question on heavy load website design using struts
Thanks Vic. We allready used PostgreSQL on a non strategic project, but our customers aren't open-source addicts (until they need to reduce costs !) Nico. FYI, one site I worked on PT (performance and tuning) we improved performance by removing replication. Also look at postgresql.org, it is much like Oracle.

Re: actions best practice question
According to MVC pattern ,alway link to action, not to JSP. This way you controler always knows what the user is doing, and you can add some logic if needed. Using a request parameter to addapt action behaviour is a common Struts use (take a look at DispatchAction). Nico. I have a login page with a link with forgot password? for users to retrieve the passwords to their email account in case they forgot it. It's pretty trivial but still using struts what is the best practice? Should the link inside the login page point to the ForgotPassword.jsp or to a ForgotPassword.do action? Currently I used a ForgotPassword.do, and in the action I check if there's an 'action' parameter with the value of 'send'. If the 'action' parameter does not exist then I locally forward to the ForgotPassword.jsp using struts-config.xml local forwards configuration. If it does exist and equals to 'send' then I perform the actual operation of going to the EJB layer and do what is necessary to do. Is this the way to do it, or am I missing the point here?

Re: actions best practice question
I use to set a specialized action-mapping for such init request, that is a simple forward (no Action class needed) /newUser/init.do = forward to newUser.jsp /newUser/register.do = RegiterUserAction = welcome.jsp^ if needed, forward to newUser.jsp can be easily changed by a full Action class (to init a form-bean with some default values for example) Nico. Nico, I agree with that, and that is basically how I did. But I was wondering for the first time the action is called, basically just for displaying the page letting the user type in the fields values and click submit, what action do you use, if any?

Re: actions best practice question
I use a Forward action-mapping : action path=/newUser/init forward=/newUser.jsp / You can use ForwardAction instead : action path=/newUser/init type=org.apache.struts.actions.ForwardAction parameter=/newUser.jsp/ I think ForwardAction is prefered when you want this request to use a formbean and have validation.

Re: Regarding the strus1.1 final release
Moving Struts to commons-ressources is planned for 1.2. I think some struts commiters where so happy doing it that they pre-include the jar in RC1, until it is not used. Nico. Hi, I had been using Jakarta-struts-1.1-rc1 version. As the final release has been done, I wanted to upgrade to it. The release notes says, the Commons-DBCP and Commons-Pool dependencies have been removed. These are replaced with a dependency on the Struts-Legacy package, containing the GenericDataSource and GenericConnection classes from Struts 1.0.2. I wanted to know that version 1.1-rc1 also included commons-resources.jar, which I don't see in the final release. Though there is a mention for the Commons-DBCP and Commons-Pool being replaced by the legacy package. But there is no information about this jar. It's not bundled in the final release. Can anyone let me know what has to be done?

Re: Acces form name in the jsp
No form-bean is associated with a JSP; Some JSP use html:tags to use form-beans.
I use some constants for form-beans so that form-bean names are duplicated only one
time : in constant definition class
and in struts-config.xml
public class Forms {
public final static String USERFORM = UserForm;
}
Then mly JSP use such code :
logic:equal name=%= Forms.USERFORM % property=editable value=true
This way I can change form-bean name without changing JSP (just need to force
recompile them)
Nico.
Hi
I want to know if there is any way to obtain the form name associated to
a JSP without put it form the strut-config.
Because, if the name of the form change on the strut-config; i have to
change the name of the form in all of my JSP's.
Example of the problem:
html:form action=/SaveReception
html:hidden property=id /
html:hidden property=stateId /
html:hidden property=editable /
table cellpadding=0 cellspacing=0 border=0 width=100%
...
...
...
logic:equal name=receptionForm property=editable scope=request
value=true
...
Thanks.

Re: IMAGE DISPLAY PROBLEM - PLEASE HELP!!
As your serlvet-mapping is setted to url-pattern//url-pattern every request is handled by Struts. Struts RequestProcessor extracts the extension to get the action path to process. request = /MyWebApp/pages/graphics/MyPicture.gif When your request is handled, they're is no action-mapping for /MyWebApp/pages/graphics/MyPicture You should use .do url-pattern for Struts actions, so that other types are directly handled by HTTP server (or container) Nico. Hello, I am having a simple problem regarding image displaying in a web application (.war). My directory structure is: MyWebApp.war - META-INF - WEB-INF - pages - graphics - MyPicture.gif - layout - upperBar.jsp The problem is: HOW to display MyPicture.gif from upperBar.jsp? I tried this: html:img pageKey=graphics.MyPicture/ In properties file I have: graphics.MyPicture=/pages/graphics/MyPicture.gif This works fine -- HTML generated contains this: img src=/MyWebApp/pages/graphics/MyPicture.gif Unfortunately, when the browser tries to download the image I get this: 2003-07-17 15:17:05 org.apache.struts.action.RequestProcessor process INFO: Processing a 'GET' for path '/pages/graphics/MyPicture' 2003-07-17 15:17:05 org.apache.struts.action.RequestProcessor processMapping SEVERE: Invalid path /pages/graphics/MyPicture was requested There are two questions arising here: 1). WHERE did the file extension go? Because I get: INFO: Processing a 'GET' for path '/pages/graphics/MyPicture' and not INFO: Processing a 'GET' for path '/pages/graphics/MyPicture.gif' 2). WHY doesn't the image get loaded? I tried to refer it in a direct way: http://127.0.0.1:7001/MyWebApp/pages/graphics/MyPicture.gif which of course didn't work either. I am using Tomcat 4.1.24.

Re: NewBie:Populating objects in Jsp
1. logic:iterate type attribute is uses to set the java type of a JSP variable set by the tag for current item. By default type is java.lang.Object, and if you don't use scriptlets (% java %) or Runtime Expression (%= java %) you don't need to use it. In the case you want to use type attribute, JSP has to import type declaration using a JSP directive % @page import= %. In your case, I don't think PUPIL_LIST items are APFM01Action instances. 2. id attribute is used to set the name of a JSP variable and a page scoped bean for the current item.

Re: Réf. : Re: How to pass parameters to a javascript popup
When you use a relative url (without / as first char) browser request the ressource
from it's current location:
For example, let's say the current URL is : http://server/context/news/consult.do
if you add a RELATIVE link to list.do, browser will send a request for
http://server/context/news/list.do;
if you add an ABSOLUTE link to /list.do, browser will send a request for
http://server/news/list.do;
html:rewrite tag is used to create absolute URI, adding webapp context at runtime :
html:rewrite page=/foo will generate /context/foo, regardless current URL is
/context/subdir/another_subdir/action.do
Nico.
Nicolas,
it works! thank you very much.
Can you explain me the magic of html rewrite tag.

Re: Using rewrite to reference HTML Assets - Tip #9 Question
Did you include the taglib definition on JSP header :
%@ taglib uri=/WEB-INF/struts-html.tld prefix=html %
Look at generated HTML to see if html:rewrite tag has been fully translated by JSP
compiler.
Nico.
Just signed up to the mailing list a few minutes ago so as you would
probably expect, I have a question that I am hoping someone can help me
with.
I'm trying to reference two javascript files but am unable to do it
successfully using the example in tip#9.
Everything works fine when I use
script language=JavaScript src=/js/overlib_mini.js/script
script language=JavaScript src=/js/calendar.js/script
when I run the app in Netbeans with Tomcat but when I move the app to
another server and it gets an application name, it loses the context
relative URL so I tried to code it using the html rewrite as tip#9
suggested but get an object expected error (it can't find the js files)
when I click on the linked image.
Can someone tell me what I am doing wrong or what else I can try to get
this to work? I have been unable to find any documentation or examples
elsewhere.
Here's the applicable code:
head
SCRIPT language='javascript'
SRC='html:rewrite page=/js/overlib_mini.js/'
/SCRIPT
SCRIPT language='javascript'
SRC='html:rewrite page=/js/calendar.js/'
/SCRIPT
/head
body
html:form
a href=javascript:show_calendar
('containerForm.containerCreatedDate'); onMouseOver=window.status='Date
Picker'; overlib('Click here to choose a date from a one month pop-up
calendar.'); return true; onMouseOut=window.status=''; nd(); return
true;html:img page=/Images/show-calendar.gif width=24 height=22

Re: Using rewrite to reference HTML Assets - Tip #9 Question
About the syntax error, just change
SCRIPT language='javascript'
SRC='html:rewrite page=/js/overlib_mini.js/'
...
to
SCRIPT language='javascript'
SRC='html:rewrite page=/js/overlib_mini.js/'
...
(no more after language attribute)
About your context, I don't know why it would'nt work. What server are you using ?
Nico.
Yes, the taglib def for html and other tags are in the header and all tags
(html, logic, etc.) work fine everywhere else.
Here's the generated html:
SCRIPT language='javascript'
SRC='/js/overlib_mini.js'
/SCRIPT
SCRIPT language='javascript'
SRC='/js/calendar.js'
/SCRIPT
Also, I noticed that I get a syntax error on the 2nd /SCRIPT when I load
the page.

Re: File Upload size restriction ?? IT DOESN'T WORK ON STRUTS-EXAMPLE

Re: External style sheets and tiles.
Struts html:link and HTML link tags are confusing. html:link is used to create a hyperlink (a tag) In your layout, you can use this : link rel=stylesheet type=text/css href=html:rewrite page=/styles/main.css/ / it use html:rewrite to build the absolute path to your css stylesheet. Nico. Is it possible to define a link to an external style sheet using html:link (or something similar)? I am using tiles and I have a base layout which contains the HEAD/HEAD part of each page. Since my link to the style sheet must go inside HEAD/HEAD, I will need to have the URL dynamically generated. How doable is this using my current tiles config? Will I need to define a layout for every level of the directory structure and use manual relative links? Am I doing something fundamentally wrong? Any suggestions would be gratefully received.

Re: Tag to remove jsp from cache???
You can configure Struts to ad HTTP no-cache headers to every response :
in struts-config.xml :
controller nocache=true/
You can add some HTTP directives to your JSP (or tiles layouts) like this :
head
meta http-equiv=expires content=now
meta http-equiv=pragma content=no-cache
meta http-equiv=Cache-Control content=no-cache
/head
Nico.
Before you send any data in the response you can
Send the following thru your response object:
%
response.setDateHeader (Expires, 0);
response.setHeader (Pragma, no-cache);
if (request.getProtocol().equals (HTTP/1.1)) {
response.setHeader (Cache-Control, no-cache);
}
%
Note, however that users can still go back in history
And resubmit their data. Browsers maintain history list
And unfortunately they do remember form data too. So if
Your user submitted a request and then clicks back button,
The browser will ask him/her if he/she wants to resubmit
the data? I saw a note somewhere in Ted's (I think) book
about how you can prevent this kind of submission on the
server side but have not explored that further. Now I
can't even remember where I saw it.
The gist of it is that before you send the form to be
submitted by the user you stamp it, and remember what is
it you still expecting from the user inside the Session
context. If user submits the form with the right stamp
the request is processed, otherwise you can tell the user
to stop resubmitting the same request.

Re: FieldChecks.validateMinLengths()
I think this is the correct behaviour since blank fields have to be considered using the required rule. You can use both required + minlength rules if field is mandatory. Nico. I started using struts validator. I just copied a bunch of stuff from the struts example and started using that, and found that the minlength validation actually returns true when the text field is blank. This was my first attempt and I was trying to make sure I had got the validator plug-in functioning correctly, so I actually spent a few hours hunting down the reason why my blank field was passing validation even though the minlength had been set to 1. I discovered in the source code that this is normal behaviour - surely that can't be the case? I would expect a blank field to fail validation for minimum length. Or is this actually the case for reasons I'm not aware of?

Re: File Upload size restriction ??
In fact I've got this strange behaviour :
- Form-bean is validated a first time.
MultipartRequestHandler.ATTRIBUTE_MAX_LENGTH_EXCEEDED is setted and an
ActionError is returned by validate().
- browser go on uploading for a long time ... (5 minutes for 10Mo upload on localhost)
- validate is called A SECOND TIME.
MultipartRequestHandler.ATTRIBUTE_MAX_LENGTH_EXCEEDED is setted and an ActionError is
returned by validate().
- browser show errors.
My code looks like Struts upload example. I certainly not understood something !

I certainly not understood something ! Nico. Tried a 135 MBytes upload on localhost. Took 10 sec to complete and the returned JSP-paged showed the correct error in the browser. Maybe you should check first, why the uploads takes so long on your machine.

Re: File Upload size restriction ??
That's what I was trying to do and discovered that upload behaviour changes when going over Struts configured file-size limit (4Mo in my case) With a 3Mo file it works fine. With a 4,4Mo file I get errors on logs but upload goes on in the browser, and after a long while (3 minutes) I get others validate() logs (related with no-file errors) and the errors are displayed on browser. I don't understand why I get TWO TIMES validate() logs !! If i set the size-limit to 6M, 4,4Mo upload works well in less than a seconds, but a 10Mo upload takes more than 5 minutes. I get file-size error logs in the first request seconds, browser stays for a (long) while and I get second validation error logs. Using IP or machine name doesn't change anything. Nico.

Re: File Upload size restriction ?? [TilesRequestProcessor ?]
I'm back with my FileUpload problem ... Here is what I've done to search the problem : I added struts-upload example classes and mappings to my app : it works I migrate it to use my classes (form-bean, actions) : it works I migrate it to use my JSPs : it works I migrate it to use my Tiles definition : it fails (browser waits 10 minutes...) Her is my mapping : action path=/upload name=UploadForm scope=request input=select validate=true type=webapp.action.UploadAction forward name=select path=tiles:upload.select / forward name=success path=tiles:upload.done / /action If I replace tiles:upload.select by /upload.jsp (that is used in body of this tile) it works fine : I get quickly an error saying file is too large. Any idea what I can do to go deeper in my bug tracking ? Nico. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: File Upload size restriction ?? IT DOESN'T WORK ON STRUTS-EXAMPLE
Making lot of tests, it seems that my problem does occur if the generated HTML is long. I made this test on struts-upload example webapp : install struts-upload.war edit /upload.jsp to add long text (I use struts-validator javascript : 730 lines ) try to upload a 2Mo file - jsp is compiled shortly after file submit - browser wait for long time before displaying error messsage Could someone please make this test on his config ? I'm not sure this troubles doesn't come from my environment (tomcat 4.1.24 - eclipse - win2k - IE 6sp1).

Re: bean:define
if groupForm.getGroupname() returns null (or ) your first bean:define will have no body content, and will so have no value to assign to the bean to create. Nico. Hi, i get the following error message in my jsp and i don't really understand why: Define tag can contain only one of name attribute, value attribute, or body content Now i use two define tags in my jsp: bean:define id=groupname scope=pagebean:write name=groupForm property=groupname//bean:define and bean:define id=curUser name=usersit property=username scope=page / Any help would be appreciated.

Re: error handling
But by doing in this way, for the forward name=failure I will always end up in
StatuicUpload.jsp
(for the below example) I don't want to goto that jsp. I need to goto the parent
page.
Let me explain the scenario once again. From two different jsps (say a.jsp and
b.jsp) I am coming to
an action (bt clicking the link in each jsp). From this action, upon an error I want
to go back to
a.jsp (if the request came from a.jsp) or to b.jsp (if the request came from
b.jsp). So here I
won't be able to hard code the path either as a.jsp or as b.jsp in the
struts-config.xml. In
you example upon error, it will always forward to StaticUpload.jsp
Thanks,
Pramod
If you really cannot set multiples action-mappings in struts-config.xml (that is the
cleaner way to do), you can add a
parameter to your request for the incoming JSP :
html:hidden name=from value=/a.jsp/
and build a new forward in your action when errors occurs :
if (!errors.isEmpty()) {
saveErrors(request, errors);
String commingFrom = request.getParameter(from);
return new ActionForward(from);
}

bean:define and JSP 1.1 restriction
Hi all, I can read in struts-bean doc this usage note for bean:define tag : There is a restriction in the JSP 1.1 Specification that disallows using the same value for an id attribute more than once in a single JSP page. Therefore, you will not be able to use bean:define for the same bean name more than once in a single page. Some of my JSPs use bean:define to compute a boolean value from other datas that is use in a logic tag later in JSP. It looks like this : bean:define id=dolink value=false/ logic:equal bean:define id=dolink value=true/ /logic:equal This code works fine on tomcat 4.1.24 and weblogic 6.1 SP5. Reading the usage note, it should not work according to JSP 1.1 spec. Someone in my team uses tomcat 4.0.6 and got errors with this mutliple bean:define. - Does JSP 1.2 has this restriction to ? - Do you think I should upgrade my JSP to be JSP 1.1 compliant, assuming it works fine on target container (Weblogic) - How to avoid using multiple times the same id (Do I need to build a custiom tag ?)
