but there is any way to use dynamic content only using tiles tags? In my
case, I have a 'setAttribute(serverLocation, Location)' function in an
Action in order to store a bean with a location information.
Location is a string (an url), so I want to use this url into a tile
definition, like this:
definition name=tracebox.def.encoderconfig
extends=tracebox.def.menu
put name=title value=encoderconfig /
put name=body value=LOCATION /
/definition
I think it must be a easy solution, using tile tags.
The way I presented to you is the cleaner one :)
If you define the put declaration in Tiles it will always be static (at
least for what I understood and read so far).
If you want to make a tiles attribute dynamic, you must specify and
implement the tiles controller (described in the other mail).
The not so clean solution is to use a tiles template with a c:import
url='${request.dynamicTilesAttribute}'/ inside.
what do you think?
I guess this is not a question of what I think... It is more of how it
works :)
This could be a nice feature to Tiles though.
One could implement a Tiles controller that made this possible. You just
needed to parse all of attributes for ${scope.Attribute} values = it would
be inneficient most of the attributes are static. If the put declaration had
a dynamic attribute (true/false) it would certainly much more
interesting/efficient. Maybe I will try and do this on my weekend ;)

Or

I think they are equivalent.
Later, if you use request.getAttribute(Receiver); (getAttribute always

If you just want to print you just need to use c:out

Until recently, the messages were always stored in request scope, so
${requestScope['org.apache.struts.action.ERROR']}
This was what I was looking for :)
In recent nightly builds, the ability to store the messages in the
session instead was added.
If something changes in the future (it seems like so) then it would only
need a test to check if the messages were on the session or request scope.
Please correct me if I am wrong.
I'm not sure I believe that this is a case where using the JSTL is
better than using the Struts tags. It seems to me that leaving the
coordination inside Struts classes is the way to go. Also, there is
no JSTL solution as clean as using the property attribute of
html:messages to filter to only include messages associated with a
specific property.
I'm all for people using the JSTL wherever its better, but I'm not
sure its better here...
You're right but it is easier for someone to start playing with JSTL
(specially if you had experience in JSP), learn the basics and start
producing code and, in parallel, making a step-by-step understanding of how
Struts works. In a team, I think this will work better (at least I hope so).
To learn Struts tags right away it requires a double effort: understanding
Struts and taglibs (I have seen this happen and it didn't turn out very
well).

Hi Robert..
I guess you could achieve the same using the controllerClass attribute and
building your class.. For instance, I have this definition in the
tiles-defs.xml file:
---
definition name=.layout
path=/common/layout.jsp
controllerClass='com.dars.XTileAction'
put name=title value=Encabezado primario/
put name=leftsidevalue=/common/leftside.jsp/
put name=rightside value=/common/rightside.jsp/
put name=header value=/common/header.jsp/
put name=footer value=/common/footer.jsp/
put name=bodyvalue=/common/body.jsp/
/definition
---
And I have this controllerClass
---
package com.dars;
import org.apache.struts.tiles.actions.TilesAction;
import org.apache.struts.tiles.ComponentContext;
import org.apache.struts.tiles.Controller;
import javax.servlet.http.HttpServletRequest;

String derecha= (String)tilesctx.getAttribute(rightside);

System.out.println( Titulo: +titulo);
System.out.println( Derecha: +derecha);
/* SetAttributes */
tilesctx.putAttribute(title, Titulo nuevo de esta vaina..);
tilesctx.putAttribute(rightside, /common/footer.jsp);
/* SetAttributes */
}
}

You can change the values of those attributes at runtime. I prefer to do
it using this method.

Well the solution for your problem is the one below.
I don't if your using velocity to generate your tiles file (I use velocity
just to build SQL/DAOs with the OJB framework).
If this is true, then you just have to make it generate a tiles file with a
controller class defined by you.
The runtime argument must be handled by you, programatically, in your own
tiles controller class.

Re: [OT] Object Design Question
On 12/03/2004 21:26, Avinash Gangadharan [EMAIL PROTECTED] wrote: People, I have a design question. It is regarding the retrieval of parent and child objects in the best possible manner. For eg. Let's say there is a Person object with properties such as ssn, lastName and firstname. It also has a list child objects ( Address ) of addresses and a list of previous employees ( Employee ). The Person, Address and Employee objects are separate tables in the DB linked thru ssn. Now what do you guys think is the most efficient way of retrieving a complete Person. If you're talking about SQL, can't you issue one or two SQL queries (with subselects, inner or outer joins) or write a stored procedure to retrieve all the info? (I am used to work with MySQL so my advanced SQL is a bit rusty) Continuing with simple SQL queries only... You could do this in a 2 step mode: - retrieve all persons who have addresses and employees (1 query per person) - for the remaining people (1-2 queries per person) - get the addresses (select... where person.ssn = address.ssn and id ...) (1 query per person) - get the employees (similar to the previous case) (1 query per person) (anyway you get 3 full table search) If you had to had 2 flags on the Person - hasAddresses and hasEmployees - you could make the queries more simple - fetch for (1-1), (1-0) and (0-0) - but maybe it would be more difficult to maintain. If you are talking about a persistence layer (like OJB - see ojb-user mailing list) some of them have lazy loading: it only loads the Person collection of Addresses only if you use them. This will certainly be simpler... And if you have object cache it could even things up (maybe you could issue a great number SQL queries but if the objects were already in cache then there would be no need for any SQL query). The simplest way is ofcourse issue 3 queries one for person, other for the list of address and the third for previous employees. But this does not scale well with increasing size of the table data. For 100 rows of Person 201 queries are issued. 1 which gets 100 persons, 100 each for there subequent address and previous employees. Similarly for a 1000, 2001 queries. Complex queries may be a solution which relies on filtering the resultset but is there a more simple and intelligent approach. Is there a problem with the inherent design itself or is this a common problem. I don¹t see any problem on the design itself (well maybe... it seems you have the social security number has the primary key... pks are not supposed to have any real meaning - what would happen if all of the social security numbers were to be changed? It would generate a huge number of cascade updates. Do whatever you like maybe I am raising a false issue here).

Re: Jrun4 Server start up error
Two months ago, I had to configure a Struts application on a JRun Server
and I had some problems to make it work correctly.
If your using Tomcat then some of the libs will be in its proper location
/WEB-INF/lib (commons-*, struts-*, and some other) but on Jrun I had to
place
log4j.properties
commons-beanutils*
commons-collections*
commons-digester*
commons-validator*
commons-upload*
struts*
log4j*
on the ${JRUN_HOME}/servers/lib.
For what I unserstood this is a JRun issue... something about loading
classes priority (servers lib, then website lib... ?! and not implementing a
Sun's specification... In conclusion, something that Tomcat does right and
JRun doesn't).
Have you tried this?
Have you checked the log files for more specific errors?

increasing. We've now hit a time out and receive the following error:
The sever did not finish starting up in the expected amount of time; it
may have failed to start.
Is there anyone on this list familiar with Jrun that could give me an
idea how to increase time for start up?
Thanks for your time and help,

JSTL: equivalent for errors and javascript
Does anyone know the JSTL equivalent for:
logic:messagesPresent
fmt:message key='errors.header'/
ul class=err
html:messages id=error
libean:write name=error bundle=ERROR_BUNDLE//li
/html:messages
/ul
fmt:message key='errors.footer'/
/logic:messagesPresent
And
html:javascript/
?
What I need is to know where the errors are stored... ?
The equivalent must be something like:
c:if test='${request.???}'
fmt:message key='errors.header'/
ul class=err
c:forEach items='${request.?}' var='err'
lifmt:message key='${err.??}'//li
/html:messages
/ul
fmt:message key='errors.footer'/
/c:forEach
For the javascript version... I think it would be something like:
c:out value='${.}'/

Hi Robert..
I guess you could achieve the same using the controllerClass attribute and
building your class.. For instance, I have this definition in the

put name=title value=Encabezado primario/
put name=leftsidevalue=/common/leftside.jsp/
put name=rightside value=/common/rightside.jsp/
put name=header value=/common/header.jsp/
put name=footer value=/common/footer.jsp/
put name=bodyvalue=/common/body.jsp/
/definition

You can change the values of those attributes at runtime. I prefer to do
it using this method.

dynaform populate

figure out how can I populate the form...
I have the following sequence:
- form A (name : gotoUserPrefsForm, id : String - user id)
- action ViewUserPreferences (uses form A)
- form B (name : userPrefsForm, severall attributes)
ViewUserPreferences {
/** @param form this is form A. */
... execute(..., form, ...) {
int id = FormUtils.getIntValue(form, id);
UserPreferences prefs = service.getUserPreferences(id);
// here starts the problem!!!
// gets the form bean configuration
FormBeanConfig fc = config.findFormBeanConfig(mapping.getName());
// this is supposed to be form B
DynaValidatorForm dynaForm = // how do I create a new instance with

Hi Pedro,
the properties are!!! important!!!
i do the following in an action:
request.setAttribute(helperBean,myValueObject);
return mapping.findForward(updateFormularPage);
and have something like that in
the forwarded jsp
struts-html:form action=/myActionPath
struts-html:text name=helperBean property=foo/
I didn't knew html:text had a name attribute :)
I usually use
html:text property=background styleClass=field_required/ (I supposed,
in this case, the name attribute is the form-bean name defined on the struts
config file)...
One more question, if you have validation errors (after submitting the
form), you still have to pass the form properties to your helperBean or the
JSP page automatically presents the previous sent values (just like doing a
back on the browser)?
Thank you again,
Pedro Salgado

Re: *.do mapping using JRun
Maybe the problem isn't web.xml.
A two months ago, I had to configure a Struts application on a JRun Server
and I had some problems to make it work correctly.
If your using Tomcat then some of the libs will be in its proper location
/WEB-INF/lib (commons-*, struts-*, and some other) but on Jrun I had to
place
log4j.properties
commons-beanutils*
commons-collections*
commons-digester*
commons-validator*
commons-upload*
struts*
log4j*
on the ${JRUN_HOME}/servers/lib.
In your case, maybe this isn't possible.
For what I unserstood this is a JRun issue... something about loading
classes priority (servers lib, then website lib... ?! and not implementing a
Sun's specification... In conclusion, something that Tomcat does right and
JRun doesn't).
You can try using Jrun locally also to check this... You can download the
software from Macromedia (the license is free for development anyway) and
check what's happening.

Hi, all,
I'm a struts newbie trying to learn with struts-example. I've got it working
great locally with Tomcat, but I'm struggling to deploy it on my ISP's JRun

I can't seem to figure out some configuration property to get JRun to
understand the *.do mapping. All of my .jsp links work great, but I get 404
errors for any link such as:
editRegistration.do?action=Create
I'm sure the solution is obvious, but I'm going blind scouring the
documentation. Thanks in advance for any help.

Re: Dynamic form property names
Sorry but I haven't quite catch what you looking for... Do you want to create a form in runtime? Is that it? If you're using a DynaForm it already has map. You can't set new properties to the form (it was built based on a DynaClass) but, if you extend DynaForm to a XDynaForm and make XDynaForm implement Map maybe you can set new properties on your new form. I used this approach (the DynaBean/Map extension) to start using DynaBeans with JSTL and, maybe... just maybe it can help you set new properties on your form. I can send you the class, if you want. As I said, I haven't tried this (the runtime form approach) and I don't know if this is what you are looking for...

Each template has various containers for content, each container can be filled by a set of different tiles. The templates are defined in a database. The definition for a template associates each container with the category of tile that it can hold, for instance a template may have containers for navigation and menu tiles. The database also contains a list of tiles that fit into each category of container. I would like to create a single form that lists the categories, that has radio button for every tile in each category. My code looks like this: logic:iterate id=elementCategory name=selectedTemplate property=elementCategories type=com.db.gci.ge.epg.actions.addcontent.TemplateElementCategory p bbean:write name=elementCategory property=category //b bean:write name=elementCategory property=description / Compatible elements in this category:br ul logic:iterate id=compatibleElement name=elementCategory property=compatibleElements type=com.db.gci.ge.epg.actions.addcontent.TemplateElement html:radio property=value(%= elementCategory.getName() %) idName=compatibleElement value=name bbean:write name=compatibleElement property=name //bbr bean:write name=compatibleElement property=description / /html:radio /logic:iterate /ul /p /logic:iterate The issue is this: I need to make the action form map-backed (I think) because the number of radio buttons is only know at runtime, but I can't find any way to name the radio buttons by the name of the category that is being selected. What I would like to use is value(%= elementCategory.getName() %) where my action form has a map and a setValue(String key, Object object) function.

There are a number of options available here, i'd have a different def
that extends showList , I'd call this base.list and then have different
defs per list.
name=user.list extends=base.list
in fact i assumed you'd only have to over load body, you could even
have a def as the value of body.

Should I:

2. Have a single master tile which chooses between various tiles and
loads the selected one? (If possible?)
3. Have a ClassController or TilesAction class which changes the tile

it. (If so how is this done? Any examples available?)
I found a couple similar references in the archives but no definitive
answer.

PS: It would be cool if you could create an action for a tile and then
do an actionForward which returns the chosen tile into the correct spot
on the calling page but I don't believe this is possible. At least
I've
never seen anything that indicated it could be done.

mapping.getForwardForward()?
Hello to everyone,
I have read Chuck Cavaness's book explanation but still I still don't
understand. If I extend an Action class then I can use the forward, include
and type attributes in any way I like, right? (the book says something about
being mutually exclusive)
action path=/Action
type=pkg.pkg1.classA
input=.tile.before
forward=.tiel.after
name=form
validate=true
/
Why I am making this question: many of my actions only use a forward
(success) and use the input attribute to go back, in case of an error.
Since I usually have 1 input and 1 forward, instead of defining the same
forward success in every action, I was hoping that I could use the forward
attribute (or any other) to send the request to a Tiles definition or JSP
resource, when everything goes well... something like:
execute() {
return (new ActionForward(mapping.getForward()));
(I still couldn't make it work properly... And I don't know if there
is any way I can do this... If it stills works with modules).
}
On those cases that I have 1 input page and more than one action that will
end up to the same input page (also very common), I solved with a
DispatchAction and use the mapping.getInputForward() to solve the problem,
but on the previous case, I think there is something very simple missing to
make it all work.
Just one more question... What is the difference of extending
org.apache.struts.action.Action or org.apache.struts.actions.ForwardAction?
I have looked at the source code and, if I override the execute() method
then it will be pretty much the same... right?
Thank you,
Pedro Salgado

Re: Naming conventions for Struts actions, Tiles definitions and JSPs
First of all the templates go to Templates directory and tile to a Tiles directory. I use two kinds of tiles definitions: those that are used to help build pages, those that are used see pages. For the build ones, I use .definition.def. For example, a one form definition would be .form.def, for a two form definition would be .double.form. The name of the major Tiles definition is the same as the JSP template. The name of Tiles definition properties are the same as the JSP files (for the initial values). definition name=.form.def path=/WEB-INF/classes/pkg/templates/form.jsp put name=head value=/WEB-INF/classes/pkg/tiles/head.jsp/ put name=header value=/WEB-INF/classes/pkg/tiles/header.jsp/ put name=menuvalue=/WEB-INF/classes/pkg/tiles/menu.jsp/ put name=errors value=/WEB-INF/classes/pkg/tiles/errors.jsp/ put name=form value=/WEB-INF/classes/pkg/tiles/form.jsp/ put name=footer value=/WEB-INF/classes/pkg/tiles/footer.jsp/ /definition For the presentation, I use the name of the extended build definition and then a name of the page. For example, a search form that extends .form.def would be .form.search which uses a search.jsp file. definition name=.form.search extends=.form.def put name=form value=/WEB-INF/classes/pkg/tiles/forms/search.jsp/ /definition The first name of the extended Tiles definition is the same as the major definition. The last name of the extended Tiles definition is the same as the JSP file. The directory where the JSP file is located, is the plural of the major definition name. If the project has a lot of roles I could also use the role to place the JSP file. Admin role value=/WEB-INF/classes/pkg/tiles/forms/admin/search.jsp/ User role value=/WEB-INF/classes/pkg/tiles/forms/user/search.jsp/ Common to more than one role value=/WEB-INF/classes/pkg/tiles/forms/common/search.jsp/ or value=/WEB-INF/classes/pkg/tiles/forms/search.jsp/ When the number of properties to be set are more than 1, I use the place where they will be presented to name the JSP files (t = top, b = bottom, m = middle, l = left, r = right, c = center...): Example: - major definition (build) definition name=.doubleform.def path=/WEB-INF/classes/pkg/templates/doubleform.jsp put name=head value=/WEB-INF/classes/pkg/tiles/head.jsp/ put name=menuvalue=/WEB-INF/classes/pkg/tiles/menu.jsp/ put name=errors value=/WEB-INF/classes/pkg/tiles/errors.jsp/ put name=topForm value=/WEB-INF/classes/pkg/tiles/topForm.jsp/ put name=bottomForm value=/WEB-INF/classes/pkg/tiles/bottomForm.jsp/ put name=footer value=/WEB-INF/classes/pkg/tiles/footer.jsp/ /definition - minor definition (see something) definition name=.doubleform.something extends=.doubleform.def put name=topForm value=/WEB-INF/classes/pkg/tiles/doubleforms/something_t.jsp/ put name=bottomForm value=/WEB-INF/classes/com/lusovencor/tiles/doubleforms/something_b.jsp/ /definition For the action to tiles name translation: Action = /ActionName - .some-major-definition.actionname Example: /ViewUser - .form.viewuser /User?operation=view - .form.user (I only use a dispatch action when getting an input from 1 form and having more than one action possibility that ends up on the input form (view user and edit user, for example)) Speaking of organizing a large project... how do you represent, in a UML diagram, Tiles definitions, forms, actions, in a way that you understand the flow of the application? Do you use the name/colors to differ actions components from form components? How can you represent a Tiles definition (I don¹t mean the tiles configuration file)?

At that time, the plug-in can decide whether it needs to reload the config or not before returning it to the action, perhaps by comparing the last modified timestamp on the config file to a value stored the last time the file was read.

Just a thought: How about extending the ActionServlet and maintain an expire-variable that is set at init-time. Then every time after a request is processed the expire variable is checked. If expired, calls the same method for loading the resources as init() does (think it's initModuleMessageResources)? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Don't block IP addresses because they can be easily spoofed and redirected. Dynamic IPs pose a problem as you could be blocking out a legitimate user. How are you storing your list of usernames/passwords? Would it be possible to add an extra bit of data next to each username/password indicating when the login is valid? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 16, 2003 9:09 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: Login Security You could put a cookie on the user's machine that expires after a certain period of time. Of course this only works when cookies are turned one and an experienced user could always manually remove their cookie. Another solution maybe is to get the user's IP address from the request Header and add it to a list of invalid IP address with their times of entry. Then upon a new request, you will have to check the list and determine how long ago the IP address was added. I'm just brainstorming here so anybody can criticize these suggestions freely. -Jonathan -Original Message- From: Ciaran Hanley [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 16, 2003 10:55 AM To: [EMAIL PROTECTED] Subject: Login Security I'm writing a web application using JSP and Struts.

Re: Log4j with Struts
Do you have the log4j jar on the WEB-INF/lib? Do you have the log4j.properties on the WEB-INF/classes? You have: String str = new String(LogonAction.class.getName()); Logger logger = Logger.getLogger(str); Shouldn't it be: Logger logger = Logger.getLogger(LogonAction.class); Pedro Salgado On 05/12/2003 06:56, Rahul Mohan [EMAIL PROTECTED] wrote: hi nick, thanks for responding...its the logger class thats missing ithink... this is the exception i get when i try to view the page: java.lang.NoClassDefFoundError: org/apache/log4j/Logger at app.LogonAction.perform(Unknown Source) what could be the problem? please excuse my novice level... thanks again.. - Original Message - From: Nick Faiz [EMAIL PROTECTED] To: 'Struts Users Mailing List' [EMAIL PROTECTED] Sent: Friday, December 05, 2003 12:22 PM Subject: RE: Log4j with Struts Well, what class can't it find, the Logger or the LogonAction.class ?

JSTL and DynaBeans
I have been using the struts taglibs and have been trying to use only
JSTL.
When using DynaBeans the JSTL doesn't work (${bean.propertyA} doesn't
print anything)
I solved the problem of accessing DynaBeans extending the BasicDynaBean
and implementing the Map interface but I am also using RowSetDynaClass
(which builds a collection of DynaBeans from a ResultSet).
I have been trying to find a solution and came to this approach:
- implement a CustomizedRowSet that is a copy of RowSetDynaClass with a
setDynaBeanClass(Class clazz). On the copy(...) method, use a
Class.forName(this.dynaBeanClass).newInstance();
Question:
- Does anyone have figured out another solution (one that is simpler and
able to reuse the methods that the RowSetDynaClass uses without copy/paste?)
?
Thank you,
Pedro Salgado

Re: R: JSTL and DynaBeans
I think that it only works for maps...
I can use DynaActionForms and use ${formbean.map[key]}, but I am using
BasicDynaBeans for the views.
