Resource files are located just like classes are -- if you declare a fully
qualified name for them (the example app uses
"org.apache.struts.webapp.example.ApplicationResources"), then your
directory structure under /WEB-INF/classes has to reflect that.

If you put your resources in
/WEB-INF/classes/ApplicationResources.properties, then you should specify
just "ApplicationResources" as the location.

I'd also scan the log files from your servlet container for any error
messages that might point you at a problem accessing the resources.

Struts uses the web application class loader to load the application
resources file for your application.  Therefore, it must either be in
/WEB-INF/classes, or inside a JAR file in /WEB-INF/lib.

In Struts 1.0, you configure the "class name" of the application resources
by using the "application" servlet initialization parameter on the
controller servlet.  In Struts 1.1, you configure this with a
 element in struts-config.xml instead.

In the Struts example application, the application resources are
initialized to "org.apache.struts.webapp.example.ApplicationResources",
which means that they must either exist as files named

  /WEB-INF/classes/org/apache/struts/webapp/example/ApplicationResources.properties

or be in a JAR file in /WEB-INF/lib with the pathname

  org/apache/struts/webapp/example/ApplicationResources.properties

My developemnet setup is similar to yours, in that a "clean" operation
deletes the entire web application output directory.  I solve this by
keeping the properties files for the application resources in the same
directory as the Java source code for the corresponding package (in this
case, the package is org.apache.struts.webapp.example).  Then, in my Ant
build script, I copy all the non-Java source files after compiling, like
this:

In my CVS repository, all the Java sources and properties files are under
"src", and all the JSP pages and WEB-INF stuff is under "web".  Thus, I
can reassemble the entire webapp under the "target" directory" any time I
want to.

If you're not using Ant, you should be able to set up something equivalent
to this with your preferred build tools.

Re: where is ApplicationResources.properties defined?

2002-07-11 Thread Kevin . Bedell



The ApplicationResources.properties needs to be on your classpath - which
implies being in the classes directoy.

If your 'clean' operation wipes out the classes directory, then your
'build' operation needs to copy the .properties files back again.

For examples of how to do this, examine the example applications delivered
with Struts. Also, review the build file for the web applications (
build-webapp.xml) to see how the web app is built.

If you have specific quesitons on the build process and how the .properties
file(s) get copied, post them back to the list and someone will help -

Best of luck,

Keivn

RE: tiles as attribute's value - is it possible ?

2002-07-11 Thread Martin Cooper


If  is really your own tag, then you could modify it to
alternatively take its value from the body, so you could use it like this:





If you still need to be able to use the 'value' attribute in other
situations, then you could have the tag look for the 'value' attribute, and
only use the body if the attribute is not present.

logon.title not found

2002-07-11 Thread bryan hansen


I am trying to take the struts-example.war and modify
it to start development. I have stripped out the stuff
that I needed to get going and am having a problem
with the ApplicationResources file. Inside the
login.jsp it specifies that it is looking for
login.title in a bean tag to display the title for
this page. Well I have included the
ApplicationResources.properties file in my war and
specified in the web.xml file the updated path to
where the file is located at and I still keep getting
hte error saying that the logon.title can not be
found.

javax.servlet.jsp.JspException: Missing message for
key logon.title

Is there something that I am overlooking on how to
include the this?

My understanding is that the 'value' field is ignored for security reasons,

dynamic mapping to specific page

2002-07-11 Thread Mutiso, Anthony


Hi,

A the following action class configuration:

ListUsersAction -> EditUserAction(userId) -> ListUsersAction
-> CreateUserAction-> ListUsersAction


ListProjectsAction -> ProjectDetailAction(projectId) ->
AddUserToProjectAction(projectId) -> ProjectDetailAction(projectId)
 
-> ListProjectsActions

This works okay.

The issues arise when I try to create the following arragement

 ListProjectsAction -> ProjectDetailAction(projectId) ->
AddUserToProjectAction(projectId) -> ProjectDetailAction(projectId)
 
-> CreateUserAction  ->
ProjectDetailAction(projectId)
 
-> ListProjectsActions

If cannot define a mapping that would take the projectId into concideration.

Has anyone had call for a dynamic map to a page the was in the middle of a
work flow / request chain?

Thanks

RE: Calls another action from one action?

2002-07-11 Thread I-Sampige, Srinivas


If I understood your question right you want to forward  to another from
within an action. You can do this like this (after reading the code pastings
read the explanation right at the bottom)-
-struts-config.xml-











--

---SingleSearchAction.java-
public org.apache.struts.action.ActionForward
performAction(org.apache.struts.action.ActionMapping mapping,
org.apache.struts.action.ActionForm form,
javax.servlet.http.HttpServletRequest request,
javax.servlet.http.HttpServletResponse response) throws
javax.servlet.ServletException, java.io.IOException 
{
//create a dummy light shortagerecord and put it in the record
container  
//contains at lease one element. This is for the RecordInfoTag to
work
//properly.
LightShortageRec  rec = new LightShortageRec();
Vector list =  new Vector();
list.addElement(rec);
RecordsContainer container = new RecordsContainer(list);
UserSessionInfo sessionInfo =
EtracSessionManager.getUserSessionInfo(request.getSession());
sessionInfo.setRecordsContainer(container);

//forward to the appropriate action to continue processing.
return mapping.findForward("retrieveLookAheadAction");
}
- 

What I am doing is, in the SingleSearchAction I am doing some preocessing
and then forwarding to the RetrieveLookaAheadRecordAction which is declared
as a forward in the declaration of the SingleSearchAction(see the
struts-config.xml).

thanks

Subject: Calls another action from one action?
From: "Hu Ji Rong" <[EMAIL PROTECTED]>

Hi,

As I described in my previous post: "Question on implementation with
frames", I have some links pointing to some pages in which all form fields
actually belong to the same domain object, eg. Airport has pages like
AirportDef, Notes, Remarks,...

So I will implement the links with one single action, AirportAction, with
parameters, the AirportAction forward to different pages based on the link
clicked. Normally, we have the submit button inside each page(form) to
submit the form. But I can't have that, the requirement is when the user
click other links, current form will be submited.(eg. when user has
completed the AirportDef page and click the next link to Notes, the form in
AirportDef must be submitted.)

So, when a link is clicked, there are two things the action need to do,
submit the current form and forward to next page. Since the forwarding is
done in AirportAction, while CRUD of AirportDef is done in AirportDefAction,
I have to call the function in AirportDefAction inside AirportAction before
forward to next page.

So the question is can I invoke another action inside one action? Or how to
achieve it?

On some apps where I've built a DAO layer (for example, with something
like a getCustomer(String customerId) method), I've built caching directly
into the DAO itself, and the used the DAO from the view layer to retrieve
needed information.  The nice thing about this is that it's transparent
to the code in the view layer that retrieves customers -- in fact, you can
do a simpleminded database lookup every time at first, and then implement
caching later if you find it to be a performance bottleneck, without ever
touching your view layer code.

Re: FormFile/DiskFile and form validation/redisplay during fileuploa d

2002-07-11 Thread Joe Germuska


I don't know of any browser which actually does anything with the 
"value" field of an input type "file".  The fact that the html:file 
tag puts a value in is just a side effect of FileTag extending 
BaseFieldTag.

Sorry.  This isn't a Struts thing, it's a browser thing.  Try making 
a static HTML form and setting some value in that field which makes 
your browser pre-fill the field.  I just tried it on Mozilla 1.0/Mac 
OS X, just to make sure I wasn't speaking too quickly, but the value 
was completely ignored.

RE: Re: Struts + EJB ?

2002-07-11 Thread Adam Young


Seems to me the real solution would be to put a session layer between the
entity and session beans.  The sesion layer would expose a serializable
JavaBean that the form could wrap, and the session bean would be
reponsible for building and processing the serialiable bean.  Trying to
get struts to do all thios for you prevents you from interjecting any
business logic into it at all.

locating DTD when upload an xml file

2002-07-11 Thread Yi-Xiong Zhou


Dear helper, 

I am using Digester to parse an xml file from web upload. The DTD file is
also in the same directory of the xml file and specified in the xml file as
. 

Could anyone tell me the best way to handle this problem? 

One way I think about is to upload the DTD file and save it somewhere in the
application directory. This directory should be specified in
ApplicationResources.PROPERTIES file. Then upload the xml file and parse it
with the saved DTD file. Could anyone tell me how to set the directory to
the parser so that the parser will know where to look for the DTD file? I
also need to know how to save the DTD files in struts to a given path. 

Thanks.

That's pretty easy to deal with, using security constraints or adding a
request filter that only accepts HTTP requests to the manager webapp from
127.0.0.1.  See the section on "Request Filters":

This is why it became pointless for Struts to attempt to act like a
container -- there's nothing you can do to force the recognition of new
classes in any portable way.  It's much better to let the container do
this, because it already knows how to load and unload webapps dynamically.

Not a problem (depending, of course, on your app server's capabilities).

If you're using Tomcat, my suggestion stands.  If you're using some other
server, check out it's capabilities for dynamic webapp reloading
(including appropriate security precautions).

RE: where can caching help performance?

2002-07-11 Thread Jamie M


on the topic of cache freshness, one idea that I
thought was interesting was something IBM was
reportedly doing for the Olympics (or some other very
high-traffic) website.  Changes to the data in the
database triggered messages to the cache to invalidate
certain cached objects.  This removes then need to
check the freshness of the cached objects.

I'm guessing at how they achieved this, but I'd expect
they were using a trigger in db2 to send an MQ message
(its very simple using these products).  Obviously
this could be achieved with non-IBM components too.

RE: Altering Configuration from command line

2002-07-11 Thread Brian Kirsch


Thanks for the responses,
I did see the reload feature of the ActionServlet.

However, we are looking to avoid going through an http interface to do the reload.
For security reasons we want the reload functionality to only be run
from the local system console.

We also want a way if possible to add new classes
(Action, FormBean, Business Logic) with out rebooting the server and have the 
ActionServlet recognized them as well. 

The goal is to be able to alter / upgrade our struts web application features
with out requiring downtime. 


Any suggestions?

Thanks,
Brian Kirsch

Have you looked into the reload action that comes with the Struts
configuration file? I know it is there under 1.0.2, and I've made great use
of it during development to refresh the container after making config file
changes.

Subject: where can caching help performance?

What approaches do people use to speed up such apps? 
Is caching really only an option in the model, rather
than the view? (assuming its not the whole page you're
caching).

I've used the OSCache tags heavily on my site along side action
components with MVC.

All views presume using the cache, but for each action, a success (on
mutate) it forwards to a separate "cache-killer" page, and then forwards
back to the view.  That way, I can remove/add/modify caching at the JSP
level, separate from what the actions do.

I've approached all of the content as being "struts heavy", yet easy to
maintain.  I compensate for this through caching which cuts repeated
page delivery by about a 3rd of the time required.

You should use your servlet container's capability to reload the Struts
web application.  For example, Tomcat supports this via the manager
webapp.

Bill,

There are no docs that I know of to point you at. We designed this 
ourselves when we were given our requirements.

We have a backend Database subsystem that contains two sub-subsystems, 
one for caching and one for data access. The API for the Database 
subsystem always looks in the cache first and then if it cannot find 
what it needs, it goes to the data access and requests the data from the 
database.

Because we know what order our shipments are scheduled to be sent to the 
packing area we are able to intelligently cache the data in usage 
sequence. So we have a background DB cache thread that makes certain 
that we have the next hour or two's data cached and also takes care of 
flushing any used data in the cache that is more than an hour old. This 
gives us a very high hit rate on our cache.

How's that for an overview?

Ed had a BOF at JavaOne this year to sort of show how he came up with 
that
tag lib and how it works. It's very straightforward, easy to use, and 
easy
to modify. I've already added a bunch of features that I'm going to

back to him, and they all were extremely easy to implement. If anybody 
has a

I'd

We have found that the biggest bang for the buck comes with pre-fetching 
data out of the database and building our business objects ahead of time 
and storing them in an in-memory cache. This means that we have a very 
large cache (we estimate at least a gig when we get fully ramped up for 
phase one and more after that), but we get phenominal throughput from 
it. Our reason for this was a maximum processing time of 3.6 seconds and 
we knew that we could not allow the database access to be the choke 
point in the system.

Concerning cache freshness, we confirm with a simple database query that 
the timestamp has not changed since we cached the data. This simple 
check takes less than 10ms, while the big multiple table joins to build 
our main object can total between a quarter and a half a second.

And of course we have database pooling active.

Hope this helps.

where can caching help performance?

2002-07-11 Thread Jamie J


I'm wondering how people speed up their MVC webapps.

Taglibs for caching parts of jsps seem like a good way
of improving the speed of a web app (see:
http://jakarta.apache.org/taglibs/doc/cache-doc/intro.html,
 http://www.opensymphony.com/oscache/tags.html, the
one that comes with weblogic etc).  

e.g. (pseudo-tag):






However they don't help much if you've got an MVC app,
because all your database access etc happens before
the view of it is rendered, as opposed to as it is
rendered  which is where these taglibs are useful.  

Is the only option with MVC to cache the data?  The
idea of caching the rendering of it too is appealing -
if they data hasn't changed, why keep re-rendering it?
(assuming everyone's view of it is the same).  It is
particularly appealing when you consider that it can
be done with no code changes - you can put a (servlet
2.3) filter in front of servlets/jsps you wanted
cached.

Its portal-style applications that I'm thinking of
here, where you have discrete components of a page
which all may involve some database (or other
timeconsuming) activity, but the data doesn't change
often so the cached view of it can be updated every
X-minutes or so.

What approaches do people use to speed up such apps? 
Is caching really only an option in the model, rather
than the view? (assuming its not the whole page you're
caching).

Re: WEB-INF/web.xml hardcoded in initServlet() [struts 1.0.2]

2002-07-11 Thread Tim T. Young

Yes VAJ/WTE is a pain, but it is ok to have the same configuration in the
webapp file and the web.xml file.

Like this...

action
*.do

and the actual servlet definition, etc.   If you deploy WAS 3.5.x running
in compatibility mode you have to do the same kinda thing in that
environment.   Everything will work in the end though.

Struts needs to know which mapping is used so that it can construct an
appropriate URL for  links where you specify the action path
only in the "action" parameter.  For example, if your struts-config.xml
says:

  ...

  ...

and your JSP says:

then Struts needs to know what extension to add (if you do extension
mapping) or what path prefix to stick on the front (if you are using path
mapping).

Struts is designed to operate only in containers that are compliant with
the specifications.  I'm not really interested in making accomodiations
for things like this -- I would suggest that WTE be changed to use the
standard deployment descriptors.

In the mean time, can you just ensure that the mapping is defined in both
files?

Does any one know of a way to reload the struts-config.xml

Can new features be added to a struts application ( action mappings, form beans, and

The Action class is *not* a servlet. Your Action classes are invoked by the
Struts request processor, which is part of the controller. In a typical
Struts application, ActionServlet is the only servlet involved.

It sounds like the  tag in your preview page is pointing directly
to your input page JSP, and not to your Struts action. If you go straight to
the page, then the Struts controller will not be involved, and your Action
class will not be invoked.

downloads (same as July 2001 release) was the last
version developed with Struts 1.0, but you can get
some later versions working with a little more effort
(getting all the extra jars).  

http://home.earthlink.net/~dwinterfeldt/


You can look at the revision info to see the changes
between the posted jars.  And all current work is in
CVS with Struts and the Commons Validator.

Re: Validator error

2002-07-11 Thread David Winterfeldt

I think you may have upgraded the Commons Validator
jar, but not Struts.  The SERVLET_CONTEXT_KEY was
removed from this class to try to completely separate
it from Struts and the web layer.  Try using the
Commons Validator that comes in the nightly download
for the version you are using.

RE: html:errors

2002-07-11 Thread Kamholz, Keith (corp-staff) USX

Yeah, that's what I do.  I make the font part of the header/footer, as well
as tags for a list.  Then the individual error messages are list items.  It
creates a very nice display.  Some consider it bad practice to use html in
your properties file, but others such as myself don't have a problem with
it.

For that why not just put the  and  elements as the

Struts needs to know which mapping is used so that it can construct an
appropriate URL for  links where you specify the action path
only in the "action" parameter.  For example, if your struts-config.xml
says:

  ...

  ...

and your JSP says:

then Struts needs to know what extension to add (if you do extension
mapping) or what path prefix to stick on the front (if you are using path
mapping).

Struts is designed to operate only in containers that are compliant with
the specifications.  I'm not really interested in making accomodiations
for things like this -- I would suggest that WTE be changed to use the
standard deployment descriptors.

In the mean time, can you just ensure that the mapping is defined in both
files?

Using the same Action for GET and POST?

Subject: Using the same Action for GET and POST?
From: "George Su" <[EMAIL PROTECTED]>
 ===

Hi, I'm still trying to get up to speed on Struts, and I'm trying to set up
an edit form.

I'm wondering, is it possible to use the same action mapping (same jsp page,
action, actionform) to handle both the GET of the page and the POST?  I do
not want to access the jsp directly on the GET.

In other words, I want /action/edit?name=foo to call my action, which I call
EditAction.  In EditAction.perform(...), if request.getMethod() is GET, I
want to populate my ActionForm bean with some data correlating to parameter
'name', so that edit.jsp can access that data.  Then I want edit.jsp called.
The problem here is, it goes into an infinite loop because the page keeps
forwarding to itself.  How can I tell it to just include edit.jsp instead of
forwarding to it?

When the edit form posts (to itself) I call EditAction.perform(...) and
since request.getMethod() returns POST, I call my business logic bean to
save the data, and forward to another page.

Is it possible to do it this way?  Is this strategy poor design?  Any advice
greatly appreciated.

Thanks,
George
[EMAIL PROTECTED]

(I'm using Struts 1.0)

In web.xml, /action/* maps to ActionServlet.

In struts-config.xml:

In EditAction.java:

public ActionForward perform(ActionMapping   mapping,
 ActionForm  form,
 HttpServletRequest  request,
 HttpServletResponse response)
throws IOException, ServletException
{
if (request.getMethod().equals("GET")) {
return doGet(mapping, form, request, response);
}
if (request.getMethod().equals("POST")) {
// call business logic and then forward to home page
return doPost(mapping, form, request, response);
}
return super.perform(mapping, form, request, response);
}

public ActionForward doGet(ActionMapping mapping,
 ActionForm form,
 HttpServletRequest request,
 HttpServletResponse response)
{
String name = request.getParameter("name");
((EditForm)form).setName(name);
return mapping.findForward("edit");
}

Re: [jetty-support] Struts problem

2002-07-11 Thread Greg Wilkins

Eric,

The opinions that I have got on this matter have been split.
But Craigs point about 8.4 is good, so I will change the next
releases of Jetty.

I'll also ask the watchdog folks to add a test for it.

I assume from section 4.4 that the URI will also have to
be re-encoded so that getRequestURI continues to return
an un-decoded URI.

There will be a 4.1.B0 release with the change in tomorrow,
which will be merged into JBoss CVS head soon after.

I'll do a 4.0.5 release shortly as well.

It will take a week or two for the change to be included
in a stable JBoss release.

cheers

Some more information courtesy of Craig:

"Per Section 4.4 (servlet 2.3), the request path elements are context path,
servlet path, and path info.  However, if you don't also change request
URI on a forward, you violate the following paragraph (also in 8.4):

 "It is important to note that, except for URL encoding
 differences, the following equation is always true:

 requestURI = contextPath + servletPath + pathInfo"

so there's no choice about updating requestURI as well."

WEB-INF/web.xml hardcoded in initServlet() [struts 1.0.2]

2002-07-11 Thread olschmeltzer


Hi !

I am using Struts 1.0.2 under Visual Age for Java 3.5.3 and Websphere Test
Environment ; the architecture is not fully J2EE. In particular, WTE does
not parse the WEB-INF/web.xml file but another file with a similar syntax
(xxx_app.webapp) : this is where it finds the mappings for the servlets
(*.jsp -> jasper ; *.do -> Struts for instance).
Unfortunately, the WEB-INF/web.xml file is hardcoded in the initServlet()
method of the ActionServlet class ; it seems that this method parses the
file to store the mapping of the current servlet. This code, in my
environment, fails, but since a catch Throwable is done, the process goes
on. But, the ServletMapping variable has not been valued.
So, my question is : though everything seems to be working all right, am I
to expect a problem because of this ? And, subsequently, why does the
controller servlet need to know the original mapping, since this topic is
handled by the servlet container ? Can I go on in this situation without
fearing a future problem ?

Thanks for any explanation.

Really dynamic forms

2002-07-11 Thread olschmeltzer


Hi !

Contrary to DynaActionForm which are rather declarative forms than dynamic
forms, I have a need for building forms that are parametric. For instance,
the Internet user specifies the number of elements he requires, and the
system builds dynamically a JSP form containing as many fields as the given
number. For instance, for a trip, he gives the number of passengers (let's
say 3) and the next form he sees contains 3 fields named for instance
passengerName1, passengerName2 and passengerName3.
Since I don't know how many fields there will be, how can I design an
ActionForm handling this ? If I were to use a DynaActionForm, I would
nonetheless be compelled to specify the fields in the struts-config.xml
file.
Hope this makes sense.
Thanks for your help.

Enhancements are just that.  They will not prevent

RE: keeping the old debate open...



Okay, if I do that and further refine it by:

All SEVERITY except enhancement
Versions 1.1b1, Nightly Build, Unknown

I am down to 23 bugs.  Is this an accurate representation of what has to 
happen before the next beta release?   Are Enhancements planned to be 
done before the next beta?

Saying there are 23 known bugs to be fixed sounds much better for the 
project than including all the enhancement requests too!

As you might imagine :-), I have a saved query on Bugzilla to select
Struts bug reports.  As of a few seconds ago, it finds 92 of them (many
enhancements, many bugs against 1.0.x, and a few outstanding against 
1.1).

The search criteria I use:
- Status = UNCONFIRMED, NEW, ASSIGNED, REOPENED
- Program = Struts

For reference, our bug tracking system (for all Jakarta and 
Xml.apache.org
projects) is at:

You probably want to take a look at the Validator Framework (standard
part of Struts 1.1, separately available for 1.0), which extends
this idea to a complete library of validations that you can declaratively
add to your forms, complete with the optional generation of client side
JavaScript to enforce the constraint on the client side if possible.

One difference from what you are suggesting is that the constraints are
declared in an external configuration file, rather than being embedded in
the page itself.  This fits my personal view of where the appropriate
separation of roles should be -- the business rules that are expressed in
validation constraints, ultimately, come from the model tier and not the
presentation tier, so they should be defined by those same folks.

Why not have tags specify simple field validation?

2002-07-11 Thread struts-user


One of the key uses of ActionForm classes is to do field validation. Often, this 
validation is simple data-type checking, or verifying that fields are non-null.

It seems like 80% of the validation tasks could be done by adding one or two simple 
optional parameters to form tags. This would allow the view to be more completely 
located in the JSPs, rather than have some presentation code be in the JSP and other 
presentation issues -- the validation -- be in the ActionForm. Putting as much of the 
view as possible in the JSP would more effectively separate developer roles, be better 
coupling, etc.

Form tags could have simple optional parameters that do things like:
o Specify that a tag value be non-null
o Specify the field's "validation data type"

Data type validators could be specified in the configuation file, in the tag handling 
code, or in special Java classes. The tags might look something like:



This would specify that this field be validated under the "SSN" set of rules. In this 
case, the validation rules could check for the 999-99- format. If validation 
fails, the error would be stored and displayed as usual.

You would only need a small library of such data type validation rules to cover most 
situations. For more sophisticated validation the programmer is free to code the 
"validate" routine in an ActionForm.

Re: ActionServlet question

2002-07-11 Thread rainer juenger


Hi Craig,

thanks a lot for your pations!

> I think we are getting confused over terminology.  The "action servlet" is
> configured in web.xml, not struts-config.xml  elements.
You are write! I am actually not talking about the ActionServlet but about
the Class Action that is a Servlet as well ;)
Sorry for not beeing clear!
I think I understood the MVC concept.

Maybe it is more easy to make me understandable when I tell what I want to
do:
I have a form that is using Struts. So all the validation and stuff works
just fine.
After all required values where put in correctly the values of the form are
beeing copied into a model bean.
(just like in the struts-example !)
Next step is to forward to a .jsp page (as configured in the same 
)that gives a preview of
inserted data. The data comes out of the model bean.
The user has now two options: Save or Edit (Save makes the persistance).
When clicken Edit the user is beeing sent back to the input form.

I thougt all this is one action! And I need only one Controler Servlet
(Action Class) for that. The options (Save or Edit) I wanted to give via the
Querystring to the Controler Servlet (/app/myinputform?action=save or
/app/myinputform?action=edit). Then the Controler Servlet would deside if
the data should be written to the DB or the from should be shown with the
preveously inserted values.

Well, I found out that the code of the Controler Servelt is only executet
once. And that is after I correctly filled out my form!
When I agan call the  via the belonging path
there is only the empty form an the Controler Servlet was not proccessed.

could I make my selve more clear???
If not I sort of write a documentation of my little test app.

thnks a lot for your help in advanc. I guess I am having a still a problem

Greetings,

I'm currently having difficulties forwarding to a definition from the config

Struts 1.1nightly - 20020707, 20020708, 20020709, 20020710.
Tomcat 4.0.4, 4.1.7
I have the TilesRequestProcessor in struts-config.xml and the
ActionComponentServlet in the web.xml.

The funny thing is, that applicationg has been working with 1.1 before.  It
broke after I downloaded the latest build but I may have changed something
else as well.

I guess I'm looking for troubleshooting hints.

The error I get is a TOMCAT 404 request resource not found. and it put a "/"
in front of the definition although I don't have one in the config file.

Thank you.

Re[2]: Should I bother to try and handle this with struts?

2002-07-11 Thread Rick Reumann

On Thursday, July 11, 2002, 12:22:57 PM, Eddie wrote:

EB> Use container-managed authentication.

Eddie, thanks for your info on container management but actually my
question really isn't about how to manage authentication. (I should
have been more clear).

It is how do you use Struts to generate form field names that will be
generated dynamically and then later have access to them to using an
Action Form or a configured Dynamic Action Form.

Let's change the whole scenario around and say I'm creating a page
that has a list of items and you have to select the favorite color of
each. For example:

car[ select options of colors to choose ]
house  [ select options of colors to choose ]
sofa   [ select options of colors to choose ]

Now the problem is that the items are generated dynamically so that
the application doesn't know until run time what these items will be.

Is there a way to have a Struts Action Form manage gather this kind of
information.

I was hoping to avoid when the above form would submit having to do
this in some business object using the request object:

//get List from db
//loop through list and during each iteration:
   String colorValue = request.getParameter( itemInList );
   //now update db with this value for this item
//continue loop

Maybe I have no choice. I'm just not clear how I can use a Struts form
to capture this dynamic list of items, since I can't configure the
fields beforehand.

Thanks for any more help

Re: struts and javascript document.write(...)

2002-07-11 Thread Virga


hi babs,
you could also use 'innerHTML', but it will not work in 'not-so-dhtml'
browser like netscape 4.7.x :-(
e.g.:
create a function to display the error message and call the function on your
validation script.

function displayError(theMessage) {
document.getElementById('error').innerHTML = theMessage;
}
function validateForm (theForm) {
   var error = false;
   if (theForm.username.value == "") error = true;
   if (error ) {
  displayError ('put your name please');
  return false;
   }
  else return true;
}

put id on  or  in your jsp page where you want to display it.
e.g.:
 
and..put onsubmit="return validateForm(this);" on your  tag.

hope it'll help

RE: Struts + MVC Philosophical question

2002-07-11 Thread Dan Cancro


My favorite reason for insulating the view from the model is because
otherwise, you could encounter errors in the middle of serving a page and
the users would see a half-finished page.  With insulation (via controller),
you can make sure that all data retrieval by a page is foolproof.  When you
don't have web pages that start going to the browser before they are totally
done being generated, you don't have to worry about this problem.

When I first started doing open source (~5 years ago), I intellectually
believed that this would be true -- it made sense.  But, beyond finding
bugs in the first place, I am continually amazed at how willing people are
to not only notice that there was a problem, but go into the source and
figure out how to fix it, so that they can provide a patch.  The Struts
community in particular has been very helpful in that regard.

Re: Should I bother to try and handle this with struts?

2002-07-11 Thread Eddie Bush

Use container-managed authentication.  For your role names, prepend a 
unique identifier for the application:

BackOfficeApp Roles:
   BOA_USER
   BOA_ADMIN

JoeBlowApp Roles:
   JBA_USER
   JBA_ADMIN

DumbApp Roles:
   DAP_USER
   DAP_ADMIN

I think that covers your needs, doesn't it?

You could then, additionally, through the container or the web-app 
deployment descriptor, specify what the role name prefix is for the 
application and use that information, combined with standard method 
calls, to determine who should see what.

If you're using Tomcat, but you're not currently using container-managed 
authentication - AND you're going to keep these folks in a database - 
take a look at the JDBCRealm.  You can also do LDAP (though I have no 
experience using it) with the JNDIRealm.  These (as well as the 
MemoryRealm - flat-file configuration - not good if you need to update 
dynamically and have it immediately visible) are "not too hard" to 
setup.  Plus, rather than having to code some "search" algorithm (ack! 
why?!  only if you have special needs is this required - the solution 
above does not qualify as a "special need"), you can make use of the 
(tried and true!) code-base that already exists in the JDK for 
determining who is in what role(s).

Container-managed Authentication == Goood

Also, using Tomcat (I can't speak for other servers because I only use 
TC :-P), you can configure the realm to be there for a context, a 
(virtual) host, or an entire server.  It gives you a great deal of control.

HTH,

Eddie

No, they don't.  The custom tags in 1.0.2 use the older version of
BeanUtils and PropertyUtils that do not know what a DynaBean is.

You can put commons-beanutils.jar into a 1.0.2 app and use dynabeans for
your back end stuff.  It's just the Struts tags that will not recognize
them.

As you might imagine :-), I have a saved query on Bugzilla to select
Struts bug reports.  As of a few seconds ago, it finds 92 of them (many
enhancements, many bugs against 1.0.x, and a few outstanding against 1.1).

The search criteria I use:
- Status = UNCONFIRMED, NEW, ASSIGNED, REOPENED
- Program = Struts

For reference, our bug tracking system (for all Jakarta and Xml.apache.org
projects) is at:

Re: Struts + MVC Philosophical question

You might want to take a look at creating a global
forward that forwards to an Action.  Create a global
forward to an Action that does the stuff you need and
then forward to the input page.  Take a look at the
O'Reilly Struts book on the theserverside.com. 
Chapter 4, page 15 under the heading of "Using a
Struts Action in the welcome-file-list".  The
explanation is better than I could give.  Hope this
helps.

Should I bother to try and handle this with struts?

2002-07-11 Thread Rick Reumann


I'm confused how I can/should handle this in Struts...

What I need to build (and long story why) is a User Administration
utility and where I'm having trouble fitting this in with struts is in
regard to the following:

Picture a case where you want to give user's certain roles based on
certain applications. So you'd have:

BackofficeApp[ select options of possible roles ]
JoeBlowApp   [ select options of possible roles ]
DumbApp  [ select options of possible roles ]

The problem is the list of applications is dynamic so I can't hard
code these values into a form bean or in my dynamicActionForm.

Currently I'm planning on doing this an old fashioned way where after
submission I'll loop through the same dynamic list of applications and
pull up the request parameters based on the values I get back. So for
example somewhere I'd end up doing:

//while loop through applications
String appValue = request.getParameter( appNameBasedOnCurrentLoopValue );
   //update db for this app name based on value
//continue loop

Can I have a form bean gather all this data? Or should I just continue
to do it the way I'm doing it?

Thanks for any comments/help.

RE: custom tags accessing database (MVC model review)

2002-07-11 Thread Jacob Hookom


I developed what I call the JFuse library which uses an action/map setup
for taking result sets and mapping them to objects as per an xml config
file:



















Datasources are aliased and defined first "cp" for example, and then
actions are bound to the datasource and callable.  Finally, JFuse gives
you the option of mapping your resultset to objects using BeanUtils as
configured by a data-map entry in the xml config.  It also implements
MVC, so either from tags:



SELECT wrkWrkID, wrkName, wrkDescription, wrkCreated
FROM tbl_workspace
WHERE wrkCltID = ?
ORDER BY wrkName

<%=request.getParameter("clientId")%>



Or from the Action:

// get context application
JFuse jfuse = JFuseContext.getInstance(servlet.getServletContext());

// insert new client in the database [setup params]
Action insertAction = jfuse.getAction("act_client_insert");
Object[] params = new Object[3];
params[0] = info.getName().trim();
params[1] = info.getServerAlias();
params[2] = "/" + info.getFileContext().trim();

// finally, update the database with new client
jfuse.doUpdate(insertAction, params);


I hope this gives you some ideas.

Subject: custom tags accessing database (MVC model review)

Hi All,

some of our development teams has implemented view helpers as custom
tags, 
which in turn access directly to database. However, we guess that such
an 
approach is not correct since it does not match Struts/MVC models.

We suggest that a better aproach would be leaving an Action to deal with

database, and making up some kind of value object, which, in turn, could
be 
used for custom tag for rendering the data.

I would be grateful for some pointer, reference or arguement against
such an 
approach or, confirmations that it is correct if so.

Thanks in advance,

Adolfo.

One of fundamental advantages of Open Source is that finding bugs generally
occurs much faster. Plus, as a user you have direct access to the bug
tracking system (bugzilla, in this case at
http://nagoya.apache.org/bugzilla/ ).

There are currently 90 open bugs for Struts. How do I know this? I just
looked - it's on-line for everyone to see. If you find a bug, you can add
one yourself and someone with appropriate rights in bugzilla will have to
address it before it dissapears - it's an extremely 'open book' approach

Hey,
This kinda depends on what errors you are looking for.  If you are using
automatic form validation, then make the validate() method simply return 
an
ActionErrors object with any error messages.  If there are no errors, 
return
null or an empty ActionErrors.  Struts will automatically take the user 
to
the input page defined in struts-config.  On that page, just use an
 tag.  If there were no errors, nothing will be displayed. 
 If
there were errors, they are displayed there.  It's pretty simple, 
another
one of those things that struts handles automatically.

Problem with session ojects: memory size, updates

2002-07-11 Thread Heligon Sandra



Sorry, my english level isn't very good.

I read that the Struts framework doesn't make (oblige) 
to use one particular model implementation (EJB, JavaDataObject,
JavaBean, ...).
But the JavaBean solution is understood or greatly recommended,
isn't it ?
Because struts uses JSP to display data and JSP pages use JavaBean
tags.
If  we work whit XML representations of  remote business objects, is
it better to
use struts XSL tags rather than generate JavaBean from the XML
description ?
The XSL solution requires to know XSL tags and  is slower and more
complex.
With JavaBean solution I am frightened having memory or request time
problem.
The user does a request, the selected Action gets business data from
the
enterprise tier, generates one or several JavaBean instances and
stores the JavaBean 
in the HttpSession. 
But the HttpSession size will grow quickly.
It is difficult to know when we have to store data in request scope
or session scope.
Has somebody advices about this dilemma? 
I am tending to put data systematically in HttpSession in order to
reduce network traffic if the user
ask again this page.
What is the max size of the session objects ? 
If we user rights on the business objects, we will have the same
JavaBean in several HttpSessions.
What do you think about this problem ? 

A last question if we have numerous session objects, when we will
have to update one
of them it will be very slow to find it in the list.
Do you have advices about that ?
Is the JavaBean/HttpSession solution realistic with "real-time"
data?

Thanks a lot in advance.

How to automaticlly set the locale according to user's request

Subject: How to automaticlly set the locale according to user's request
From: "Alex Kwan" <[EMAIL PROTECTED]>
 ===
Hi, All
I want to build a multilanguage site with structs. As we all know, the
response encode the content to client using the charaterset defined by
setLocale() or setContentType().If the we don't set the locale, it will use
the default "ISO-8859-1".
Now the question is:
1.I want to setLocale() by the value get from request.getLocale(), but how
can I set the struts to automaticlly finish this process.
2.How can I set the web to make jsp also automaticlly encoding the content
using the client locale setting.

Thanks.

FormFile/DiskFile and form validation/redisplay during file upload

2002-07-11 Thread Galpin, Charles


Hi All

I've searched the list for this issue, and only found one thread that was
related (pre-setting the file value), but didn't really address this issue.

I have a form with a file input as well as other inputs (assume they are
metadata associated with the file).

If the user enters a path to a file and submits, and my validation checks on
the other inputs return ActionErrors for those inputs, the form is
redisplayed but the file value is not retained.

If I view the source, I see



So it looks like DiskFile needs a toString() implemented that returns this
path. BUT, I think this is not going to be as easy to fix as it sounds. The
DiskFile class only has the original filename and the full server side path,
but not the original client side path.

Am I missing something, or does anyone know how I can get the full client
side path to the file? I scrounged around the upload source a bit, but can't
see where this would be done. Also, it does not appear that the original
filename is guaranteed to be supplied either ( see
http://www.ietf.org/rfc/rfc1867.txt)

Oh, I am running the nightly snapshot (20020711) to get past other file
upload problems under weblogic 7.0.

Thanks
charles

We run out of bugs to fix when everything in Bugzilla is marked
resolved, later, or won't fix. =:0)

We publish the current development version each and very night. Many
developers download this and try it against their own products, which is
where the bug reports come from. 

We do have a few unit tests of our own, but our real test-bed are the
thousands of developers who monitor this list and test it for
themselves.

Absolutely everything we do is out in the open. There are no private
developer lists. If you, or your boss, or anyone want's to know what's
going on, they only need to follow the DEV list. 

At any point in time, the worst-case scenario is that you can adopt the
source into your own product and go your own way. So there's nothing to
lose, and several world-class developers like Craig McClana to gain.

AW: change an Actionform

2002-07-11 Thread Efftinge, Sven


Ok, here it is:


  


  


  
  





  


Here are the two jsp-formulars :

SearchPage.jsp:




  

and EditPage.jsp:





  


and in the action this doesn't work:

ActionForm myForm = new EditForm();

myForm.setDataobject(EntityFassade().findByValue((SearchForm)form.getValue()
));
request.getSession().setAttribute(mapping.getName(),myForm);

and this also doesn't work:

ActionForm myForm = new EditForm();

myForm.setDataobject(EntityFassade().findByValue((SearchForm)form.getValue()
));
form = myForm;

in both cases the EditPage.jsp formular is empty.
But in the Action the dataobject isn't empty I have tested that.

dynabeans as value objects in struts 1.0.X

2002-07-11 Thread Adolfo Miguelez



Hi All,

I quick question with a quick response. I have successfully tested to create 
value objects as dynabeans in Struts 1.1b1. Custom tags are able to inspect 
themselves dynabeans (from Commons - BeansUtils package).

However, in production we still have Struts 1.0.2 and we planned switching 
only to Struts 1.1 when it be released.

On other hand, we intend to implement a generic value object for all our 
apps. From the reasons above, it seems that a dynabean based value object 
should be fine for Struts 1.0 applications.

The question is: Does struts custom tags are able to inspect properly 
dynabeans in Struts 1.0.2 as they are in Struts 1.1?

Thanks in advance,

Adolfo.

Hmmm
I haven't done it myself, but I don't see why you couldn't.  It seems like
it would work fine.  However, I have had problems with the
 and  tags when trying to
display something if a collection is empty.  It made me lose faith in the
tag, so now I use the  tag for these types of
situations (with a preceding  tag for collections).  Did you try
your idea yet?  Like I said, it seems like it should work just fine.
However, I am new to all this, so if I'm wrong, somebody correct me.

Hey,
This kinda depends on what errors you are looking for.  If you are using
automatic form validation, then make the validate() method simply return an
ActionErrors object with any error messages.  If there are no errors, return
null or an empty ActionErrors.  Struts will automatically take the user to
the input page defined in struts-config.  On that page, just use an
 tag.  If there were no errors, nothing will be displayed.  If
there were errors, they are displayed there.  It's pretty simple, another
one of those things that struts handles automatically.
