Creating a bean at run-time from xml-file.

[Simon Kelly]

Hi all,

Not too sure whether this is at all possible, but can you dynamically create
a new class during run-time from an xml-file?  I ask as this as I may have
some xml files that are not defined in a DTD/Schema but I would need to put
them into a bean.

Cheers

Complete tutorial on Digester?

[Simon Kelly]

Hi,

Does any one know of a good, complete, tutorial on Digester and all it's
uses?  I've got a couple of small example based ones but they don't really
deal with the more complex xml structures or how to handle recursion within
xml.

Cheers

RE: The best way for learning struts (stupid question)

[Jacob Hookom]

If you want to do up a simple application that involves persisting data,
here is what you want to start out with (includes open source library
recommendations):

First you need to do RDD Analysis, which is Responsibility Driven
Design.That means, make a list of everything you want your
application to do, usually this is referred to as an FRD or MRD in some
circles (Functionality/Marketing Requirements Document).  Note,
sometimes the requirements documentation is proceeded by Use Cases or a
narrative of how a user interacts with the application.  Once you have
all your requirements listed, you, as a programmer, should start
grouping or assigning these requirements to hypothetical services or
layers.  Remember it is good to have lots of layers (well, not more than
5 or 6 in most cases).  Sometimes these steps are accompanied by
extensive FUDs (F***ed up diagrams) to help get your ideas down quickly
(including your site map of all the pages).

Once you have your requirements broken up to layers, start defining the
objects that will accomplish your application's goals.  I usually lay
out my whole application in interfaces before actually ever creating an
Object.  This will force you into the Bridge Pattern methodology along
with extensive uses of the Factory or Factory Method Pattern.  This is
the key for pluggable design.  You will need to think about things such
as how transactions will take place-- like what are the steps for
creating and validating a User.  Usually these flows are taken from Use
Cases or from FUDs.  Match each step with a service layer and an object
to take care of it.

Now for the gritty technical stuff.

Persistence:
If you have a RDBMS available to you, such as SQL Server or MySQL, then
the easiest route is OJB (don't let others tell you differently,
especially if you aren't a follower of Joe Celko, author of "SQL for
Smarties").  OJB is available at Jakarta's web site and works perfectly
with the concept of interfacing all of your business objects.  The neat
thing is that OJB will take care of all the SQL stuff for you.  Granted,
it will take a few days to get OJB setup, but the development process
goes VERY FAST once everything's setup.

Another option is storing data as XML.  Don't learn XML unless your boss
wants you to or if you get a kick out of learning other people's syntax.
There are a few libraries available to you such as Digester, Castor, and
Betwixt.  All three libraries will take care of automatically converting
your Java Objects into well formatted XML and visa versa.  I recommend
Betwixt for the beginner because everything is VERY simple.  It also
extends the Digester Libraries in reading XML and converting it to a
Java Object for use.  If you want to go hog wild with lots of
customizability, then check out Castor (www.castor.org).  I've used it
on a few projects and I'm quite happy with it.

The Fire Break
Now, back to layering...  As per my original email, we would want to
isolate the persistence layer, so put in an intermediate service layer
that acts like a curtain.  We can call this intermediate layer the Fire
Break.  The Fire Break hides your persistence layer from Struts so if
you end up changing the persistence layer, you don't have to change any
of your controller or view level code.  The Fire Break in itself can act
like a controller or container of services, not only for persisting
objects.  You could write up a Fire Break so it operated like such:

FireBreak fireBreak = FireBreak.getInstance(servletContext);
PersistenceService pServ = fireBreak.getPersistenceService();
pServ.store(myEmployeeObject);

By looking at the code, we've hid the persistence implementation via
interfaces so to the Struts Action, we don't know if we are storing
myEmployeeObject as XML or in a DB, we just know it was stored.  Of
course, you might want to setup some kind of transaction object where
you ask the PersistenceService for a transaction object to use, and then
do all of your persistence tasks, then commit them or roll them back to
assure the ACID properties.

NOTE:  If you are doing up something fast and gritty, then feel free to
throw the persistence layer calls in your Struts Actions, I will show an
example below of how to do this with OJB.

Controller (Struts):
If you did your job correctly above, your code in the Action's execute()
method should be less than 20 lines, possibly 10 lines:

// example without firebreak

public ActionForward execute(Blah blah blah)
{
 EmployeeForm empForm = (EmployeeForm) form;
 try 
 {
  PersistenceBroker pb = pbFactory.getPersistenceBroker();
  Employee empObject = new EmployeeObject();
  BeanUtils.copyProperties(empForm, empObject);
  pb.store(empObject);
 }
 catch (Exception e)
 {
// do exception handling
 }
 return mappings.findForward("success");
}

That's all there is to it if you have your EmployeeForm pre-validated
with the Validator libraries.  One thing t

Recursion is handled by specifying leading "*/tagName" in your path
specifications.  I used it in my CacheFilter implementation that allows
you to setup trees of caches via the Composite Pattern.

// from my ServletCacheRuleSet extends RuleSetBase
public void addRuleInstances(Digester digester)
{   
digester.addObjectCreate("*/cache", "type",
CompositeServletCache.class);
digester.addSetProperties("*/cache");
digester.addSetNext("*/cache", "addServletCache");
}

// from my ServletCacheConfig (this.rules is a ServletCacheRuleSet)
public ServletCache createCache(InputSource inputSource) throws
IOException, SAXException
{
ServletCache cache = this.createCache();

Digester digester = new Digester();
this.rules.addRuleInstances(digester);
digester.push(cache);

digester.parse(inputSource);

return cache;
}

For more complex examples, check out Strut's source code, Craig or
whomever wrote all the configuration/setup procedures with Digester.

To resolve your problem, here is what you can do : write

 initTable("table0");

   after the tag "" of your table. The script only needs the 
contents of the table to be loaded. Putting the code on the onLoad event of 
the body make sure the script is executed after the whole page has been 
loaded, but putting this line of code instead, at the bottom of the page, 
works fine, I've just tested it.

Action without forward ?

[Marcus Biel]

Hi, I am using Struts 1.02 and got the following Problem:
I need to create a JSP where u can select to create a pdf or excel file.

The problem is, I didn't programm the Action to create the file, a
colleague did.
So I need some way to call his Servlet. I tried to map directly to it,
that did not work. So I wrote an Action that called a method to create
this pdf / excel file,
depending on the parameters given.

The problem is, that after this method there is no forward anymore, as
the control is given to the servlet
to create the file, and thats it. But the   
public ActionForward perform(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
{

needs some forward.
For the moment I wrote "return null" but imho thats no prober solution.

Maybe you got an idea.


thanks,

marcus

Re: How to let a user click a column header to sort data in a t ab le u sing struts?

[Marcus Biel]

Hi Sandra.
For each column header you need a link that gives the required
parameters to your Action.
You can add 1 static and one dynamic parameter.
If you need more dynamic parameters, you need to add a map.

Without map:
Column Name

With MapMap:
Column Name

And have a look at:
http://localhost:8080/struts-documentation/struts-html.html#link
http://localhost:8080/struts-exercise-taglib/html-link.jsp


hope this helps.

Re: Action without forward ?

[Nicolas De Loof]

perform() method in any action MAY return an ActionForward, but CAN return
null if it has build the response for the client browser. This is commonly
used for PDF or Excel generation, where they're is no need for a JSP.

I don't understand why you cannot directly use the PDF-generator servlet, by
adding a dedicated mapping in your web.xml.

How to set a parameter in an action

[Oliver Kersten]

Hi,
in my action-class I can get a parameter from the request by using the
method getParameter(String); from the class HttpServletRequest.
But now I want to set a parameter (not an attribute) in my action and then
make the forward so that another action can read this parameter.

I need it because normally the action gets the parameter by the URL. But in
this special case I have to send the parameter by an action.

ciao Oliver.

Re: How to set a parameter in an action

[Nicolas De Loof]

Servlet API doesn't allow you to write request attributes (parameters,
headers...)

You can try to forward to a new ActionForward object, build with the mapping
to your "another" action, adding needed parameter with GET syntax :
...
return new ActionForward( NEXT_ACTION_URL + "?param=" + paramValue );
(I'm not sure it will work...)


Another solution is to put param value in request and forward to a JSP that
will redirect browser to the NEXT_ACTION_URL with param added :

# in your action:
request.setAttribute("param", paramValue);
return new ActionForward( "redirect.jsp" );


# redirect.jsp :

  ">


document.forms[0].submit();

LookupDispatchAction, setting parameter?

[Cook, Graham]

Small problem, I am using the LookupDispatchAction to handle multple
actions, SAVE, DELETE etc. In my JSP page i have a 'submitAction' text
field. When the value of 'supplierNumber' has been entered the 'onchange'
event will set the 'submitAction' field to the value 'SEARCH' and then
submit the form. The LookupDispatchAction then uses this 'submitAction'
value to determin what action to take.

The problem I have is that the field doesn't seem to change value, anyone
got any ideas???


Heres is the JSP page:-

...
...
...
function setAction(target) {
document.forms[0].submitAction.value=target;
document.forms[0].submit();
}
...
...

Re: changing ActionForm to be a Java interface

[Dan Jacobs]

Hi Craig,

Based on the oft misunderstood property of contravariance, I *do* 
conclude that form-beans should not be subtyped from Java Beans, for the 
reason that subtypes are never supposed to have fewer behaviors than 
their supertypes.  It's customary in good object-oriented design to use 
delegation rather than subclassing to use only a selected subset of 
behaviors from another kind of thing.  If Struts is saying that a 
form-bean should never act like a bean in such-and-such manners, then it 
follows that form-beans should not be beans.  This *is* an architecture 
issue.

I don't dispute the popularity of Struts, and I congratulate you on 
that.  But that's not grounds for justifying any and every aspect of its 
implementation approaches.  Windows 98 was popular too.  I think most of 
Struts is very well done, and I also think there's this specific problem 
with form-beans, long indicated by the persistent and ongoing level of 
misunderstanding surrounding them.

As for the beans introspector, you can still use that in your 
implementation if you want to go that route, and you can additionally 
ignore non-String beans properties, or any of a number of things like 
that to rein in misuse.  But as long as you call form-beans java-beans 
but intend somethimg more restrictive, there will be confusion.

A similar situation I ran into recently was one where a client 
implemented a ClassLoader solely for the purpose of being able to locate 
resources using a directory path.  But it wasn't actually able to load 
classes.  It was probably convenient to implement it as a subclass in 
order to inherit certain methods directly, but that didn't help when the 
next person actually attempted to use the thing as ClassLoader.

Subject: Re: changing ActionForm to be a Java interface

Hi Craig,

Well, I concede that this is not the sort of change to make for the 1.1
release.  But I still think that the underlying problem behind the
chronic misuse of form-beans is that they're described as beans, but
they're not really meant to be beans.  So I do still recommend
revisiting that aspect of the framework design.  What the framework
seems to intend here is a raw-form-data-holder with a little extra
support for validating raw form-data, etc.  What it's providing is a
please-dont-use-all-the-functionality-of-a-java-bean instead, and that's
confusing.



Just out of curiousity, how do you conclude that an ActionForm not a
JavaBean?  It follows all the requirements of the JavaBeans spec (it's a
*class*, not an interface; zero-args constructor; naming patterns for the
getters and setters; support for BeanInfo overrides if you really want to
use different method names).  In fact, standard form beans wouldn't work
at all if the implementation class's bean properties could not be
introspected correctly by javax.beans.Introspector.
   ^


But come on, this isn't a human factors issue, it's an architecture
issue.



Good luck succeeding with that attitude :-).  After being a key player in
the two most successful (measured in users) projects at Jakarta -- Struts
and Tomcat -- I can confidently assert that almost *everything* important
about a successful software project is a human factors issue.
Architectural purity is a primary concern only for architects (which is
obviously why you care about this).


If you imagine the possible causes of chronic and consistent
confusion in traditional building architecture, I'm sure you'll follow
the analogy back again.  I think Struts is a terrific idea, and I'd like
to see it improve.  I'd also like to use more of JPlates functionality
in Struts applications, but JPlates already works much better than JSPs,
so that'll do for now.



A couple of million downloads since its inception says we didn't do half
bad on the architecture of Struts -- at least from a user perspective :-).


Anyway, best of luck with the 1.1 release.



Thanks ... and good luck with JPlates as well.

It writes the binary value(pdf) into the response.getOutputStream,
with content-Type "application/pdf" und with content-length set.
But in the browser nothing can be seen, even though the pdf that gets
created correctly,
and the browser is loading the pdf-plugin.


Any ideas ?

I never set content-length when generating response (PDF or not). Perhaps
you have a mistake in length calculation and browser waits for EOF ? Try
without.

Hi Craig,

Based on the oft misunderstood property of contravariance, I *do*
conclude that form-beans should not be subtyped from Java Beans, for the
reason that subtypes are never supposed to have fewer behaviors than
their supertypes.  It's customary in good object-oriented design to use
delegation rather than subclassing to use only a selected subset of
behaviors from another kind of thing.  If Struts is saying that a
form-bean should never act like a bean in such-and-such manners, then it
follows that form-beans should not be beans.  This *is* an architecture
issue.

I don't dispute the popularity of Struts, and I congratulate you on
that.  But that's not grounds for justifying any and every aspect of its
implementation approaches.  Windows 98 was popular too.  I think most of
Struts is very well done, and I also think there's this specific problem
with form-beans, long indicated by the persistent and ongoing level of
misunderstanding surrounding them.

As for the beans introspector, you can still use that in your
implementation if you want to go that route, and you can additionally
ignore non-String beans properties, or any of a number of things like
that to rein in misuse.  But as long as you call form-beans java-beans
but intend somethimg more restrictive, there will be confusion.

A similar situation I ran into recently was one where a client
implemented a ClassLoader solely for the purpose of being able to locate
resources using a directory path.  But it wasn't actually able to load
classes.  It was probably convenient to implement it as a subclass in
order to inherit certain methods directly, but that didn't help when the
next person actually attempted to use the thing as ClassLoader.

Re: Action without forward ?

[Marcus Biel]

Because then I wouldnt have a request processor.

The rest of the application is written in struts and uses the request
processor to
check wether the user is logged in or not.

If not, he gets forwarded to the login page instead of creating a pdf.

Small problem, I am using the LookupDispatchAction to handle multple

event will set the 'submitAction' field to the value 'SEARCH' and then
submit the form. The LookupDispatchAction then uses this 'submitAction'
value to determin what action to take.

The problem I have is that the field doesn't seem to change value, anyone
got any ideas???

Hi Sandra.
For each column header you need a link that gives the required
parameters to your Action.
You can add 1 static and one dynamic parameter.
If you need more dynamic parameters, you need to add a map.

Without map:
Column Name

With MapMap:
Column Name

And have a look at:

hope this helps.

Digester getting recursive tag types.

[Simon Kelly]

Hi all,

I am trying to load a set of beans using the Digester.  One of the beans
(Menu) will contain beans of the same type within.  The basic layout of a
page follows with what I think is the correct way of dragging in recursive
tags (IE SubMenu is of type Menu).  Can anyone verify if this is even in the
right ball park?

Cheers

Simon.

I can't run it yet cause I'm only part way through workig out how to extract

Oh - so you want to sort at the client side.

that's always on the server side.

Maybe but in this thread there was a script which did this, so that's the

setting dynamic values in a ActionForm when it creates

[Carl-Jakob]

Hi
 
 Im using a multibox and figured out that if "selecteditems" and "id"
has the same value the box is "checked". 
 


 
Since it also is selecteditems i get the values of the users choice on
submit I must use someForm.selecteditems as property.
 
What I need to know is how do i set dynamic values in selecteditems in
someForm before i use multibox in the JSPpage? Can I set values from the
session attribute when someForm creates? 
 

RE: Action without forward ?

[pqin]

My writer writes binaries to output stream.

Stmt is an Oracle BFILE, response is HttpServletResponse, length doesn't
matter.

InputStream in = null ;
BufferedInputStream bis = null ;
ServletOutputStream writer = null ;
 
try
{
stmt.openFile() ;
in = stmt.getBinaryStream() ;
bis = new BufferedInputStream(in) ;
int length ;
byte[] buf = new byte[512] ;
writer = response.getOutputStream() ;
response.setContentType("application/pdf") ;
while ((length=bis.read(buf))!= -1)
{
writer.write(buf) ;
}
}
finally
{
if (writer != null)
writer.close() ;
if (in != null)
in.close() ;
if (bis != null)
bis.close() ;
if (stmt != null)
stmt.closeFile() ;
}
}

In my Action class, I return null.

It works perfectly if Adobe Acrobat Reader is installed.

It writes the binary value(pdf) into the response.getOutputStream,
with content-Type "application/pdf" und with content-length set.
But in the browser nothing can be seen, even though the pdf that gets
created correctly,
and the browser is loading the pdf-plugin.


Any ideas ?

Controlling amount of log messages in Struts 1.1

[John Fairbairn]

Hi,

I'm using Struts 1.1-b2 within Websphere Studio Application Developer 4. I am getting 
an excessive amount of messages logged to my console such as:

0 [Thread-1] INFO util.PropertyMessageResources - Initializing, 
config='org.apache.struts.util.LocalStrings', returnNull=true

10 [Thread-1] INFO util.PropertyMessageResources - Initializing, 
config='org.apache.struts.action.ActionResources', returnNull=true

3265 [Thread-1] INFO util.PropertyMessageResources - Initializing, config='UIStrings', 
returnNull=true

I tried setting the debug param to 0 when configuring the ActionServlet with no 
success:



action

org.apache.struts.action.ActionServlet



application

UIStrings

 



config

/WEB-INF/conf/struts-config.xml





debug

0



2 



I'd like to have no log messages written to the console or any other files. 

Thanks,

John

Re: Action without forward ?

[Kris Schneider]

Can't you just have the action that "fronts" the PDF servlet return a forward
that represents the path to that servlet?

web.xml:


  pdfServlet
  /pdf


You could also include a  element to ensure that clients
can't make direct requests to the PDF servlet.

struts-config.xml:

ActionForm defaults for primitive wrapper types

[Steve M.]

I noticed a change in the Struts 1.1-b3 release that
ActionForms which use primitive wrapper Objects for
their bean properties, default to the corresponding
primitive type defaults instead of null if the
HttpRequest contains any value for the property name,
including empty string.

Example:

when submitted to ActionForm:
Integer test = myActionForm.getTest();

struts 1.0.2: test = null
struts 1.1-b3: test = 0

In this case I cannot tell if a user entered 0 or
nothing.

It appears this is related to changes in the Commons
BeanUtils package. Is this the desired behavior going
forward?

That was what I was thinking about, but I thought it would allow user to get
direct request to pdf-servlet. I never used  (nobody's

The first form entry is possible because of the ValidatorActionForm class.
from:

http://jakarta.apache.org/struts/api/org/apache/struts/validator/ValidatorActionForm.html

"This class extends ValidatorForm and provides basic field validation based on an XML 
file. The key passed into the validator is the action element's 'path' attribute from 
the struts-config.xml which should match the form element's name attribute in the 
validation.xml."

So - I have an action name logon, and form bean logonForm which extends
ValidatorActionForm.  Action logon uses logonForm. I am guessing that -
when the path of action is executed, the "logon" validation entry gets
executed (and ignores the "logonForm" entry?)...

There is probably something missing from my question (due to probably still
lack of understanding of this). I'll have to just play with it :)
Thanks for having patience..

Date format

Hi,

Please excuse me for the off-topic question, I need this urgently, so
posting it.

How can I get the current date format? (style: DateFormat.SHORT, locale:
Default)

I used:

SimpleDateFormat formatter = new SimpleDateFormat() ;
String format = formatter.toPattern() ;

It gives:

M/d/yy hh:mm a

But what I want is *only* the date part, excluding the time part of it.

Thanks,

The empty  element causes all client requests for the collected

[tiles] suggested importAttribute improvement

[Graham Carlyle]

I've started to use tiles recently and think its great way of enforcing 
consistency and reducing duplication across JSP pages. However the 
importAttribute tag doesn't feel right to me...

Rather than the importAttribute tag bringing all the parameterized 
variables into the page scope, how about a custom tag introducing just 
one named (or implicitly named) Map of the parameters?
This seems more consistent with the other JSP scoped attributes (page, 
request, session, application) as the tile parameters are just another 
scope.
To preserve backwards compatibility this tag could be named differently.

So rather than...

...


How about...

...


Admittedly this does make the tile more verbose, but it has the benefit 
of making clearer the distinction between a tile parameter and other 
page scope attributes.

This would also get round the need for the importAttribute tag's 
"ignore" attribute being set to true when a null parameter value is 
potentially passed into a tile.
The use of "ignore" attribute in this situation doesn't seem appropriate 
anyway as I am intentionally passing a null parameter into the tile.

Hi,

I have my Action Servlet  to react with the servlet mapping "/do/*".

I have the feeling this does not work when I am using Struts Modules.
Anyone who got modules working with this servlet mapping ?

RE: changing ActionForm to be a Java interface

[Sri Sankaran]

The logic validate method is so closely coupled with the form-bean properties that it 
wouldn't help to look at a sample.  What I do in form-bean-X's validate() is nothing 
like the validate() for form-bean-Y.  If you still want to look at sample code you 
should be able to find it in the sample applications that ship with Struts as Mark 
pointed out.

Also, please create a new thread when asking a new question.  Not only is it impolite 
to piggy-back on an existing thread you are more likely to get responses with a new 
thread with an appropriately titled subject line.

Hi Craig,

Based on the oft misunderstood property of contravariance, I *do* conclude that 
form-beans should not be subtyped from Java Beans, for the reason that subtypes are 
never supposed to have fewer behaviors than their supertypes.  It's customary in good 
object-oriented design to use delegation rather than subclassing to use only a 
selected subset of behaviors from another kind of thing.  If Struts is saying that a 
form-bean should never act like a bean in such-and-such manners, then it follows that 
form-beans should not be beans.  This *is* an architecture issue.

I don't dispute the popularity of Struts, and I congratulate you on that.  But that's 
not grounds for justifying any and every aspect of its implementation approaches.  
Windows 98 was popular too.  I think most of Struts is very well done, and I also 
think there's this specific problem with form-beans, long indicated by the persistent 
and ongoing level of misunderstanding surrounding them.

As for the beans introspector, you can still use that in your implementation if you 
want to go that route, and you can additionally ignore non-String beans properties, or 
any of a number of things like that to rein in misuse.  But as long as you call 
form-beans java-beans but intend somethimg more restrictive, there will be confusion.

A similar situation I ran into recently was one where a client implemented a 
ClassLoader solely for the purpose of being able to locate resources using a directory 
path.  But it wasn't actually able to load classes.  It was probably convenient to 
implement it as a subclass in order to inherit certain methods directly, but that 
didn't help when the next person actually attempted to use the thing as ClassLoader.

problem with messagesPresent?

I'm using  to test for messages when displaying

There are form errors







However, I am seeing 'There are form errors' on my page even when there are
no ActionMessages or ActionErrors (like when the page is first loaded).

I test for that on my JSP using some scriplet code that is outputting 'no
messages'/'no errors':

Object msgobj = request.getAttribute(org.apache.struts.Globals.MESSAGE_KEY);
if(msgobj == null) {
response.getWriter().println("no messages");
}
Object errobj = request.getAttribute(org.apache.struts.Globals.ERROR_KEY);

RE: Struts taglibs - Is data grid possible

[Haseltine, Celeste]

You must be coming from a VB background, as a DataGrid and a MSFlexGrid are
both MS COM components.

The equivalent of a COM component in Java is an applet.  But I caution you
on using applets in a web/browser based application UNLESS you are writing
an application for intranet (read: internal company) use.  For internet use,
where the general public will be using your web site, many of your IE users
will have problems running an applet, and will most likely give up on using
your site, rather than trying to figure out whether they have the right
version of the JRE installed on their machine, along with IE, to run your
applet.

You might want to check into using DBForms tag library instead of writing an
applet.  You can get more info on DBForms at
http://jdbforms.sourceforge.net/.

Where did you get that idea?

The Java version of a COM component is like using a JavaBean in a jsp page

I come from a VB/ASP background and COM has no similarity to an applet.  COM
is server-side technology and applets are client-side technology.  The
closest similarity between Java and M$ would be JSP = ASP/VB Script.

Also, it is easy to auto-download the correct JVM to IE if an appropriate

RE: Struts taglibs - Is data grid possible

[pqin]

COM is similar to CORBA/RMI but not CORBA, am I right?

I come from a VB/ASP background and COM has no similarity to an applet.  COM
is server-side technology and applets are client-side technology.  The
closest similarity between Java and M$ would be JSP = ASP/VB Script.

Also, it is easy to auto-download the correct JVM to IE if an appropriate
JVM is not found.

You must be coming from a VB background, as a DataGrid and a MSFlexGrid are
both MS COM components.

The equivalent of a COM component in Java is an applet.  But I caution you
on using applets in a web/browser based application UNLESS you are writing
an application for intranet (read: internal company) use.  For internet use,
where the general public will be using your web site, many of your IE users
will have problems running an applet, and will most likely give up on using
your site, rather than trying to figure out whether they have the right
version of the JRE installed on their machine, along with IE, to run your
applet.

You might want to check into using DBForms tag library instead of writing an
applet.  You can get more info on DBForms at
http://jdbforms.sourceforge.net/.

Hi,

I need to implement Data grid using Struts. Can anybody guide me to how
about doing this? Do we have any taglib, which can do this?

Action Servlet

[JONATHAN PHILIP HOLLOWAY]

Could somebody tell me if it's possible to get a handle on the action servlet 
from an action class and if so how this is actually done.

Many thanks in advance,

Specifying Application Root in links

[Pani, Gourav]

I am using Struts 1.1 with Resin 2.1.5 and have encountered the following
problem.

Whenever I try to link to an action mapping specified in my
struts-config.xml file within a JSP, I have to specify the application root
in the path.  

For example, the following is my setup in struts-config.xml.

  

  


The following is my setup in web.xml.

However, in my JSP I have to link in the following manner.  "bpo" is the
application root as determined by the war file.

Click Here to get to Catalog

I would instead like to be able to do the following

Click Here to get to Catalog

The same goes for recognizing the /images directory under the application
root.  I would rather keep it in my war file build than let Apache control
image display.  

I think this is a simple configuration issue and possibly a novice mistake.
Could someone help me out with this. 

Thanks in advance.
