iterate - help

[Rodrigo Zerlotti]

Sorry if it is too basic, but i am new on struts...

I have an interate:


   do something


multiCity is a vector...

Suppose I want to display on a table only 2 at the time, I make offset="0"
and lenght="2".

How do I repeat the loop without repeating the logic iterate for [2,2} and
[4,2], or in other words, how can I set the offset/length on the fly?

It is the same question for all struts tags, I can never use <%'s to modify
values of the tags... - of course I may be missing something

Relative URL problem in action taglib processing

[[EMAIL PROTECTED]]

We have encountered a minor problem using Struts with our back end
architecture at Fidelity Investments.

Using Struts version 1.0, all action references always end up translated
to absolute paths when the JSP is translated to HTML.  For example, an
action="foo.do" in a JSP is later converted into action="/foo.do" in the
resulting HTML file, even if it actually needs to remain a relative
reference "foo.do" in order to work in our back end architecture.  This
is no real surprise I suppose, as the use of the absolute slash is
mentioned in the Struts specification.

As a result, we are considering hacking the Struts code in a couple of
places to strip the absolute slash off of the front of the action
reference path name before writing the HTML, and then re-adding it back
again on the action mapping.  After some investigation, it appears that
this hack can be isolated to two spots:

1.  org.apache.struts.util.ResponseUtils.write :
 Code to strip the prefixed slash from the beginning of the
action="" string just before it is written out to the response.

2.  org.apache.struts.action.ActionMappings.findMapping :
 Code to prefix  the slash back onto the front of the action=""
string (assuming the mapping can't be found without it).

This seems to be the least painful solution because it seems to be
isolated to two spots in the code and it does not involve hacking any
taglibs which we don't want to touch since we would forever be hacking
new taglibs for the rest of time.

Preliminary testing would indicate that this hack does seem to work, but
I can't help but wonder: are we missing something?  Is there an easier,
more elegant way to achieve relative paths in action parameter
references?

Thanks,

David McLure

This is not going to be possible.

Frames and Targets are a client-side thing.  Servers don't have any clue
about them -- they just respond to requests.  You will need to make sure
that the  or  that *initiated* this request sets the
appropriate target value so that the response comes back where you want

RE: cannot find the datasource in struts?

[Bradley Cowen]

I can show you an example of what i'm using (MySQL):

In struts-config.xml:

  

  
  
  
  
  
  
  
  

  

Then, you can set up a TestAction.java action class with a perform method
like this:

public final class TestAction extends Action {
public ActionForward perform(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
 HttpServletResponse response)
throws IOException, ServletException {
Connection connection = null;
DataSource dataSource = null;
Statement statement = null;
ResultSet resultSet = null;

try {
dataSource = servlet.findDataSource(null);
connection = dataSource.getConnection();

statement = connection.createStatement();
resultSet = statement.executeQuery("SELECT FirstName,LastName
FROM People "
+ "ORDER BY LastName,FirstName");
resultSet.close(); // just a test
} catch (SQLException sqle) {
getServlet().log("Connection.process", sqle);
} finally {

//always close connection
try {
connection.close();
} catch (SQLException e) {
getServlet().log("Connection.close", e);
}
}

// Forward control to the specified success URI
return (mapping.findForward("success"));
}
} // end TestAction

RE: Reuse of JSPs

[JEWeaver]

Thanks Nicolas and Larry..

Both the use of templates (although I need to check and see if that is
available in 1.0 or not) and the parameter in the path of the forwarding
seem like they should prevent JSP duplication.  For this particular
problem, I'm leaning towards the request parameters at the moment - since
the target JSP has slightly different buttons available as well as
boilerplate differences.

Looks like there is a struts-template tld in 1.0, so both solutions
available to me.  I have typical header / footer and sidebar type stuff
that looks like the template approach would be good for, so I will probably
end up using both of these techniques.  Again, thanks.

RE: Back Button in Struts

[Pete Gordon]

They need to be set on the HttpServletResponse object.  

Not being as familar with struts as most people on this list... I am going
to take a stab at this... Somebody help me here

In looking at the Controller Servlet (ActionServlet) I found that it has a
nocache member variable on the default Servlet.  This sets the Headers,
although I don't know what headers without looking at the source.  Somewhere
within the ActionServlet you would need to get a reference to the
HttpServletResponse (it is passed around a lot, and then call the setHeader
method with ("Expires", "0").  Of course, this may not be needed if the
nocache does it for you; although  I would imagine that it does the
Cache-Control and/or the Pragma.  I am not that familar with those Headers,
but we had problems with them because they would erase the content in a form
with the back button was used.  We wanted it to go to the server and keep
the content in the form that was entired previously--the Expires Header was
all we needed.  

In case it's not obvious we aren't using Struts.  We created a J2EE
architecture that is very similar in that it uses MVC, action concept, and
templates (we call it conduct); and I am trying to get more familar with
Struts to find the gap and overlaps between the two architectures.  To
hopefully someday come in under the struts framework and share some of our
architecture with the struts world.

Thanks,
Pete Gordon

You can't really use the javascript:history.back() function to hit the
Action class as the history.back does not even hit the webserver.  It is an
internal "client" operation, like most javascript is.

One solution you might want to try is to create a stack object for each
session to track what "actions" they have run.  Then you can implement a
fairly decent "back" button.

[BinhMinh Nguyen]

hi all,
I have a very interesting problem, and here how it
occurs:

my formJSP have two button: SUBMIT and EXIT.
if the user is authenticated, when the Submit button
is clicked, the form is submitted succesfully and the
user is brought to another JSP page, let say Thank-you
page.

But let say, if the session is timed out. Then the 
user is brought back to the loggin page and is forced
to log-in again, after entering usrname and password
and press enter, the browser show a blank screen while
the user is supposed to be redirected to the Thank-you
Page. It seems that the servlet is not retained the
destination: Thank-you page at all.

Is that a problem with STRUTS, TOMCAT or Did I miss
anything in in setting up the servlet?

Thank you very much.

RE: Reuse of JSPs

[nicolas bonvin]

if I understand correctly what you'd like to achieve, one way to do it would
be to use the Templates or Tiles tag library:

- you setup one template: /CarMenu.jsp with the reusable HTML code :
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>


...





- you use one jsp page for selectRentalCar aka /SelectRentalCar.jsp which
simply uses the CarMenu template and provide it with the appropriate message
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>

selectRentalCar text


- and you use another jsp page for addRentalCar (/AddRentalCar.jsp) which
also uses the CarMenu template
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>

addRentalCar text


it's good practice to store your templates under the WEB-INF/ path to
prevent direct access from browser requests (internal access from Servlets
or JSPs will still work, though).

of its use to be sure if there is a Struts object on the request that I can
expose to determine this value

Alternatives?

Have a look at the following messages which discuss the addition of such
feature.
In this message you'll find some source code that can help you until
hopefully this gets into the commons.

The options tag doesn't permit the use of a Hashmap. A Hashmap is not
actually a
Collection, since it doesn't implement the Collection interface. Perhaps
this
utility is a possible enhancement for the options tag.

Dynamic form generation.

[Sastry Varanasi]

I am trying to use dynamically generated forms with Struts. Since the form 
is dynamic I will not know the form fields until runtime. How do I define 
my FormActionbean in this case? Is there a  way to circumvent the 
requirement of having a Bean for holding the form data? Can anyone help me 
out with some ideas on this?

Thanks,
Sastry.

Interate - ideas?

[Rodrigo Zerlotti]

Sorry if it is too basic, but i am new on struts...

I have an interate:


   do something


multiCity is a vector...

Suppose I want to display on a table only 2 at the time, I make offset="0"
and lenght="2", how do I repeat the loop without repeating the logic iterate
for [2,2} and [4,2], or in other words, how can I set the offset/length on
the fly? It is the same question for all struts tags, I can never use <%'s
to modify values of the tags... - of course I may be missing something

TIA

I had the same problem until I started from "scratch" with a clean tomcat +

I think there was an XML parsing problem using an appropriate version of
jaxp.

let's try this:
1) unpack tomcat4.0b07 into a $TOMCAT_HOME
2) copy $TOMCAT_HOME/jasper/jaxp.jar and $TOMCAT_HOME/jasper/crimson.jar
into $TOMCAT_HOME/lib
3) copy the tiles-webapps into $TOMCAT_HOME/webapps
4) make sure your CLASSPATH is minimal (contains just .; (Win) or .: (Unix)
is the best)
4) start tomcat and go to http://localhost:8080/tiles-doc

if it works, try your custom application.
otherwise let me(us) know.

Actually all the options suggested would solve my doubt. :-) Thanks guys!

I think I'll go with the subclass/"realPerform"/postPerform way, which

RE: Antw: Re: Error 500 : No action instance could be created

[Toni Charlot]

It sounds as if Apache is not forwarding the *.do request at all.  You may
have to modify your httpd.conf file to add the following:

JkMount /*.do ajp13

depending on the version of Tomcat you're using.  I haven't try this myself,
so it's probably worth a try.

good luck.

Re: Tiles && Struts

[Matt Raible]

This error is caused because you are calling the wrong ActionServlet, in
web.xml, replace  with the one below, and add the init-params.

You will also need to make sure that all the commons*.jar packages are in your
WEB-INF lib directory.

After doing this, the only error I am getting is:

java.io.FileNotFoundException: ...\WEB-INF\tilesDefinitions_en.xml (The system
cannot find the file specified)

java.io.FileNotFoundException: ...\WEB-INF\tilesDefinitions_en_US.xml (The
system cannot find the file specified)

Anyone know how to get rid of these?

RE: referring to hashmap elements with struts...

[Rey Francois]

Have a look at the following messages which discuss the addition of such
feature.
In this message you'll find some source code that can help you until
hopefully this gets into the commons.

Subject: referring to hashmap elements with struts...


Hi there.

I have an Action that's tossing a very nice HashMap object at a Struts page.
Is there a way (using Struts) that I can refer to the individual values in
the Hash by using their keys?  I see how I would iterate (although I'm not
crazy about this functionality), but that's not what I'm interested in: I
need to be able to use the key/value pairs.  After all, isn't that what
makes a Hash so helpful?

Thanks,

Andy

RE: Back Button in Struts

[Pete Gordon]

You can also look at putting in the Expires HTTP Header parameter to force
the client to hit the server each time.  This forces the back button to go
back to the webserver.

//These Response Headers prevent Client side cache of web pages
//response.setHeader("Cache-Control", "no-cache");  // don't do
this -- prevents back button
//response.setHeader("Pragma", "no-cache"); //
don't do this -- prevents back button
response.setHeader("Expires", "0");

You can't really use the javascript:history.back() function to hit the
Action class as the history.back does not even hit the webserver.  It is an
internal "client" operation, like most javascript is.

One solution you might want to try is to create a stack object for each
session to track what "actions" they have run.  Then you can implement a
fairly decent "back" button.

Haven't done this myself, but know of another project that has.

need help with struts installation

[Chuck Carroll]

Hi,
 
 I am a new user of the struts package 
and am using Tomcat 3.2.3 on Windows 2000 Professional with service pack 1.  I have tried to follow the directions on 
the installation of Tomcat, as well as that for struts.  “Normal” servlets and JSPs work just 
fine, so I think Tomcat is okay.  
The problem is with the struts-example from Jakarta.
 Before I install the struts package, I can 
start Tomcat with no errors.  After 
I install the struts package and start Tomcat, I get the message:
 Call 
org.apache.struts.action.ActionServlet.addServletMapping(action/java.lang.String,*.do/java.lang.String)
New 
org.apache.struts.webapp.example.User
Begin event threw exception
java.lang.ClassNotFoundException: 
org.apache.struts.webapp.example.User
    
at …
When doing …/struts-documentation, everything 
seems to be okay.
When doing …/struts-example, I get the 
message:
Error: 500
Location: /struts-example/index.jsp
Internal Servlet Error:javax.servlet.ServletException: Missing message for key index.title    at … However, …/struts-exercise-taglib works for the BEAN Tags and LOGIC Tags but fails on the HTML Tags with the message:

Internal Servlet Error:javax.servlet.ServletException: Exception creating bean of class org.apache.struts.webapp.exercise.TestBean: java.lang.ClassNotFoundException: org.apache.struts.webapp.exercise.TestBean
I am obviously doing something wrong, but can’t 
figure out what it is.  Any help 
would be very much appreciated.  
Thank you.

Tiles && Struts

[Trieu, Danny]

Craig,

I found Tiles to be very interesting.  However, I have a few question
regarding Tiles, that I hope you can help me with or point me to some
sources that I can get my answer from.  

My question is I wrote a simple Tiles jsp, and verything work fine till I
introduced the Definition feature of Tiles and I got this exception:  

javax.servlet.ServletException: Can't get definitions factory from context.

This happens the same when I tried to deploy and run the 3 sample apps the
bundled with the distribution I downloaded.  I am run
tomcat4.0b07+Struts1.0+Tiles

I emailed Cedric Dumoulin Cedric Dumoulin ([EMAIL PROTECTED]) but haven't
heard form him.  Please let me know of any list or people that I can ask
question related to Tiles.

Thanks,

danny

Re: bean:message tag

[Matt Raible]

The problem is that my image changes depending on the error message - so I need
a way of determining which image to display.

Oh well, I do everything from the design to the Action servlets, and stop
before the EJBs - so I guess it's only really a concern if someone else was
doing the design.

In modern JVMs (1.3 and later), reflection costs are lower than ever
before -- to the point where they are usually not noticeable compared to
database and network latencies.  Even if they become an issue, it's purely
CPU time, so that is relatively easy to fix.

If you write apps that use EJBs, you're doing a *ton* of Java reflection
behind the scenes already.  In general, I wouldn't worry about it,
especially if it helps you maintain a cleaner and more maintainable
application architecture.

Re: Validator::validate() reflection - null

[David Winterfeldt]

I didn't think it would cause a problem.  I'll look
over it again.  If a field is of type int, you don't
need to validate to see if it is an int.  Also if you
have a field defined as an int, then you don't know if
someone entered something bad because you will always
get the default value of the field.  So on the
ActionForm level it is good to preserve the user's
input so if it fails validation you can return the
value the user entered so it can be corrected.  So an
ActionForm normally uses Strings except for
checkboxes, radio buttons, and select boxes where you
know the user can't enter anything bad.  Then you can
have a bean with all the correct types (int, Date,
etc.), and convert the ActionForm's values to the
other bean.  There are a couple of transformation
packages posted to help with doing this type of
conversion between objects.  Here is the link.

Re: Can't find message Resources or DatabaseServlet

[chuck amadi]

Hi all , I have a MyApplicationResources at the following level .

wardens/WEB-INF/classes/org/breconbeacons/wardens/MyApplicationResources
wardens/WEB-INF/src/org/breconbeacons/wardens/MyApplicationResources

I have also declared the above path in my web.xml.and consructed a DatabaseServlet
in preparation for connection pooling . The path has also been set as above
and web.xml.

Note only the ActionServlet is set to org.

I intially used a dbTags (taglib) and evrything worked fine but i want to
subtract all the scriptlets out of my html code and utilise the html,form,base
and links tags that are availble
and make better presentation of the view jsp pages.

So why is my message resource missing as i have set the path as above and
not as below error.To MyApplicationResources - and amended  the DatabaseServlet
and message resource in the application web.xml file accordingly.

Any Suggstions - Cheers Chuck

AW: SilverStream behind firewall

[Stuber Urs]

Thank you for your input! Unfortunately I still get the message

resolveEntity('null',
'file:///C:/WIN32APP/SilverStream37/bin/struts-config_1_0.dtd') Not
registered, use system identifier

after copy and paste your suggestion, and my app still doesn't work as soon
as I select something related to the struts-config file (e.g. a *.do
action). At least the app server doesn't hang anymore - after trying
"http://localhost/myDB/app/dtd/struts-config_1_0.dtd"; it completely refused
to restart and I had to erase the db and create a new one...

Not even the jakarta struts-example works. Today we had an external
specialist at our site. He could run the struts-example at his company,
using SilverStream, whenever they use a firewall there too, but he wasn't
able to get it running here. He tried another workaround which he was
teached in a SilverStream ePortal education, namely to put the DTD's into a
HelpDB and access them with a http://localhost... link, but after deploying
that (successfully) to the app server, the latter refuses to work again and
hangs after the resolveEntity message.

On the other hand we experience no problems with struts 0.5, using
action.xml without a DTD validation.

We've asked SilverStream support now. Do you have an idea why your
workaround works at your site, but not at ours?

RE: Re[2]: Multiple input fields

[SUPRIYA MISRA]

Try using an Arraylist in your setter and getter instead of a string array. 
Also System.out the setters and getters to make sure they are being called.

AW: Antw: Re: Error 500 : No action instance could be created

[Bernhard J. Hirschmann]

Hi Marion,

it sounds like you missed to declare your action in struts-config.xml. But
in your first posting you've written that you did the mapping... Maybe you
have the wrong package name and/or class name in struts-config.xml ? You
should check this.

>type="com.servlets.thisandthat_action">

is "thisandthat_action" really your action class?

RE: Re[2]: Multiple input fields

[Michael Terry]

Kent -

Can you give an example of how you did this? I used an ArrayList
in my form, with one entry per select element in my form. This
works fine when only single options can be selected, but I can't
get it to work with 

In my JSP I want to generate a variable number of multiple select
boxes containing values taken from a Hashtable containing
ArrayLists of beans (one entry in the Hashtable for each box):

  <% int n = 0; %>
  
<%
  prop = "attList[" + n + "]";
  n++;
%>


  

  

In the associated form bean, I use an ArrayList named attList which will
contain the variable number of String[] arrays of selected values passed
back from my select boxes. So I have my getter and setter thus:

public String[] getAttList(int idx) {
return (String[])attList.get(idx);
}

public void setAttList(int idx, String[] keys) {
attList.set(idx, keys);
}

But the problem is that this collapses in BeanUtils.populate with a
type mismatch error:

  javax.servlet.ServletException: BeanUtils.populate
at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:486)
  Root cause: 
  java.lang.IllegalArgumentException: argument type mismatch
at java.lang.reflect.Method.invoke(Native Method)
at 
org.apache.struts.util.PropertyUtils.setIndexedProperty(PropertyUtils.java:688)

There is no problem when I remove the multiple=true from the select element
and use the following:

public String getAttList(int idx) {
return (String)attList.get(idx);
}

public void setAttList(int idx, String key) {
attList.set(idx, key);
}

I've already posted this problem once, but answer came there none.

Michael

Actually, you can do one better than that.  Just pass in beans to the
form(can have collections in them), and that way you don't have to put a
bunch of attributes and getter/setters in your form.  Of course you will
need a getter for your bean that you put in your ActionForm.  As a result,
my ActionForms are very thin, take advantage of reuseability, better
performance, and alot less work.

Hello there,

Although  I have not tried it personally, I read from the list that it
can  be  done  if  your  ActionForm  provides  a  setter which takes a
collection and a getter which returns a collection.

Antw: Re: Error 500 : No action instance could be created

Hi Jon,

my action class look just as you described.
But I looked closer at the error message and discovered that it goes like this:
500 R< /thisandthat.do + null> No action instance...

So it seems like the parameters don't go through !
Still my action class doesn't even do a system.out.println, so I doubt that the 
request is passed on to the class correctly.

Re: Generating Dynamic Urls with

[Bill Clinton]

Hello,
 I don't believe you will be able to do this with the struts link 
tag.  But it should be fairly easy to make your own custom tag that 
would do this.  Take a look inside the source code for the link tag.

Expresso integration with Struts now available - v4.0ea Released

[Flying Cloud]

I wanted to let your guys know that Early access (ea) Expresso 4.0 release
is now available for download - which is fully integrated with Apache
Jakarta Struts.  Expresso 4.0 is a big jump forward from 3.11, as the
version number indicates, it includes a number of substantial changes to the
core API - mostly related to Controller objects, now that we are fully
integrated with  Struts. Please see the release notes at
http://www.jcorporate.com/doc/release.html. We look forward to your comments
and feedback...

With Release 4.0ea Expresso has made Controller objects available to Struts
as Actions, so the URL mapping, configuration, and other great capabilities
of Struts are available - with all of the advantages that Expresso standard
Web application functionality provides such as Controller object, DBObjects
(object-relational mapping), configuration management, security, database
connection pooling, email connectivity, job control, logging, event
notification, caching, internationalization, and more. The Controller
servlet (ActionServlet) still handles dispatching, then the specific
Controller object provides the UI-independant business logic.

Expresso 4.0ea is intended as a release for users who want to learn about
the new features and assist in the quality assurance process and
documentation - it is *not* ready for production use, and problems should be
expected at this stage. We'd very much appreciate bug reports and input on
this release - and this can be discussed here on the forums.

The 4.00ea version is available as a '-complete.jar' file - see the
http://www.jcorporate.com/doc/expressocomplete.html file for documentation
about installing this version. The -complete version is bundled with
Apache's Tomcat 4.0 b5, and includes doc, javadoc, and many other things
that you don't necessarily want in your own production release of an
application - it also, however, includes the 'ant' build.xml scripts to
create other versions of Expresso, including fully binary versions, .war
files for quick web-application deployment, and so on.

In order to control the size of the download, the '-complete' file does not
include the source for 'external' packages, such as Struts (although it does
contain the full Struts Javadoc for reference). All external package doc can
be found in CVS if it's required (for reference only). We also exclude the
Tomcat examples and Javadoc - both of which are available of course in the
full Tomcat download from Apache's site directly.

We look forward to your comments and feedback...both here and on our own
listserv and forums onsite.

Re: Error 500 : No action instance could be created

[Jon Crater]

you should be able to do what you're trying to do without a problem.  do you 
have an action class which extends org.apache.struts.action.Action and which 
is called "com.servlets.thisandthat_action"?  if not, that's the beginning 
of your problem. if so, inside that action class, you should have something 
like the following inside your perform method to determine where to forward:

// assuming someValue is a string and is already initialized
if (someValue.equals("display"))
  return mapping.findForward("display");
else if (someValue.equals("back"))
  return mapping.findForward("back");

supplying more of the relevant code would be helpful.

Re: bean:message tag

[Thomas Quas]

Matt,

what I'm currently doing is something like this: In, say, x.jsp I write

...
 class="feedback">






whereas in AppRes.properties I have

login.error.1=...
login.error.2=...


Yeah, it is rather uncomfortable--and only necessary if you really need
to have support for i18n--but I can be sure that after a designer
changed the page design there are no disturbing effects coming from my
language definitions. The designer can concentrate on the .jsp file and
does not need to care about language--in the ideal case ;-)

The same concept should work for your table header definitions.

Re: session ids

[Guus Holshuijsen]

You can retrieve the current user's "session id" from the
HttpSessionBindingEvent e using "e.getSession().getId()". Use this value to
look up an entry in your hastable and remove it.
The HttpSessionBindingEvent is generated when the session is invalidated
(valueUnbound())  or created (valueBound()).

For more details read the Java doc on HttpSessionBindingEvent. Make sure
your class maintaining the hashtable implements the
javax.servlet.http.HttpSessionBindingListener interface.

Re: bean:message tag

[Matt Raible]

Tom - it seems that you are correct, my html does show up correctly.

The reason I have html in my properties file is because I want to display
certain images with my messages.

Let's take the following key for example:

error.password.mismatch=Invalid username and/or password,
please try again.

I can probably move ... into my jsp page, but I'm already
using error.header and error.footer with html, so this seemed natural:

errors.header=
errors.footer=

I could probably also parameterize my  so that this could be a
different key in my properties file, but then I'd have to add a little more
code to my action classes (or validation.xml file).

This brings up another point - I wish I could dynamically set the path to my
image, using a scriptlet or  tag, meaning replace "/dc/common" with
"<%=pathToImages%>" - but doesn't seem to work.

We get all our static files through the webserver (vs. appserver) - that's why
I can't get it from the war.

problems while trying to initialize a Connectionpool

Hello !

i am encountering problems by trying to initialize a
Database Connnectionpool.

in struts-config.xml I got the entries:









but by trying to acces these values by the call

 try {
 GenericDataSource dataSource =
(GenericDataSource)servlet.getServletContext().getAttribute(Action.DATA_SOUR
CE_KEY);
  conn = dataSource.getConnection();

  .
 //here are my MySQL instructions etc..

I got a NULLPOINTEREXCEPTION
If I initialize these values directly via the call
dataSource.setAutoCommit(false); Etc  inside the method
erverything works.

BUT I HAVE TO READ THESE VALUES FROM THE STRUTS-CONFIG!

Re: method reflection in action classes

[Ted Husted]

A very good example of coding this sort of thing is the DispatchAction
class in the Struts Action package.

http://jakarta.apache.org/struts/api/org/apache/struts/actions/DispatchAction.html

If you are worried about performance, it would be very easy to use
DispatchAction to combine several of your existing Actions together, and
then use jMeter to run some load tests. At this time, things like the
cost of reflection can be vary by setup.

struts light bug ?

hi all,

does anyone have experience with struts light from jean noel ribette ? i
have a problem with his menu tag. i have implemented a wonderfull deep
search and want to create a tree-menu with the results now. i have created
the necessary code, but this could not be correctly realized. the struts
light flips out ;-) , when there are two menu items like that:











! --> problem start here:   
1.  
2.  









the output shows like that:

menu.test.menu1 
menu.test.menu3 
menu.test.item2 
menu.test.item2 
menu.test.menu4 
> menu.test.item4   
> menu.test.item4   
menu.test.menu3 
menu.test.item2 
menu.test.item2 
menu.test.menu4 
> menu.test.item4   
> menu.test.item4   

does anyone have an idea, or the mailaddress from jean? his
[EMAIL PROTECTED]   is not
availeble now. the example on his page works
(http://struts.application-servers.com/).

Craig, when you say :
"Note that you *must* specify an input attribute on your , so that
Struts knows where to send the user back to."

What do i need to do, what is the name of this input attribute?
Do you have an example of struts-config.xml code matching the case.

Here is mine:


http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd";>








 


 




I beleve there is something missing in the action node, but what?
Perhaps struts does not know what page to display when finding errors. How
can i tell it where to go? (another forward???)

Hi all,
This my first mail to the list. I am just learning Struts. I got stuck at a 
problem hope I will get some help reg. this.
Problem:
  I am displaying a list of orders with links at the end like "Modify Order", "View 
Order" etc. Ok now these links point to specific directories in the context depending 
on a key passed from the Server.
Currently in non-struts based model I do it like this
blah
 blah..

Now how can I achieve the same dynamic url generation using struts. 

Any help.

Thanks in Advance,
Jiger

Excuse me for being late in my response but i'm currently between too
projects...

Craig, when you say :
"Note that you *must* specify an input attribute on your , so that
Struts knows where to send the user back to."

What do i need to do, what is the name of this input attribute?
Do you have an example of struts-config.xml code matching the case.

Here is mine:


http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd";>








 


 




I beleve there is something missing in the action node, but what?
Perhaps struts does not know what page to display when finding errors. How
can i tell it where to go? (another forward???)

Thanks for help.

The above code looks OK -- what about it doesn't work?

Note that you *must* specify an input attribute on your , so that

RE: What is Titles? and what gonna happens to template tag in thefurture?

[Trieu, Danny]

Ted,

Thank you for answering my question.  I found Tiles to be very interesting.
However, I have a few question regarding Tiles, that I hope you can help me
with or point me to some sources that I can get my answer from.  

My question is I wrote a simple Tiles jsp, and verything work fine till I
introduced the Definition feature of Tiles and I got this exception:  

javax.servlet.ServletException: Can't get definitions factory from context.

This happens the same when I tried to deploy and run the 3 sample apps the
bundled with the distribution I downloaded.  I am run
tomcat4.0b07+Struts1.0+Tiles

I emailed Cedric Dumoulin Cedric Dumoulin ([EMAIL PROTECTED]) but haven't
heard form him.  Please let me know of any list or people that I can ask
question related to Tiles.

Thanks,

danny

No, the reset has to be done, otherwise the checkboxes would not
work.

including other actions

[Andreas Leitner]

Hi,

>From within Action.perform, I can return an ActionForward. This way I
can subsequentially go from one action to the other. That's fine, but
how can I "include" other actions. I would like to activate several
other actions from within one action, and at the end return a final
forward to a jsp.


Tia,
Andreas

This would work of course, but it seems wrong, since now there is 
something on the form which ties behavior of the form (model) to the 
page (presentation).  If I move fields from one page to another, I'll 
have to modify the form bean.

It seems to me that struts *shouldn't* reset form beans that are 
stored with session scope.  Or am I misunderstanding something?
