Title: checkbox: isChecked 





I'd like to take the information if the checkbox shoud be checked not from the formbean, but from a different bean. 


See the example:


%// the bean where the check-information comes from %
jsp:useBean id=warenkorb class=ufa.database.shop.Warenkorb scope=session /



%// I can get the information like this %
bean:write name=warenkorb property=bestellung.editPosition.artikel.shoudFeedBeChecked /



html:form action=warenkorbBearbeiten.do 
 % // how can i check the box acording to the information in bestellung.editPosition.artikel.shoudFeedBeChecked %
 html:checkbox property=feed / 


/html:form 



I've looked through the archive, but found nothing. Any ideas

MessageTag: How to specify a variable number of replacement parameters ?

2001-09-24 Thread Priyanka Siriwardena


Hi

org.apache.struts.taglib.bean.MessageTag takes replacement parameters
(optional argument) as shown in the following example:

bean:message bundle=MyMsgBundle key=MyMsgKey arg0=aaa arg1=bbb/

This is fine as long as I know exactly how many replaceable parameters to
put.

say I get an unknown number of replaceable parameters as an array depending
on the key (key is dynamic as shown below):

bean:message bundle=MyMsgBundle key=%=msgKey% /

So say the key MyMsgKeyOne may have replaceable parameters a1,a2
and say the key MyMsgKeyTwo may have replaceable parameters
x1,y1,xy,zz.
and so on...

The same message tag must handle all these situations.

How do I specify a variable number of replaceable parameters in the message
tag?

thanks

Re: Struts and XML


It's not a Struts issue, just conflicts between parser versions.

The configuration mentioned is a documentated alternative for Tomcat.
Many applications need Xerces available this way.

Hi

When we try to install our application on tomcat 
3.2.3 using struts we recieve a exception

java.lang.ClassNotFoundException: 
org.apache.struts.action.ActionFormBean

we have struts.jar in WEB-INF/lib and all our

We have removed the jaxp.jar and parser.jar from 
tomcat/lib directory and replaced it with xerces.jar

What can cause this problem 

Thanks in advance

Who tells the Checkbox if it should be checked or not?

Title: Who tells the Checkbox if it should be checked or not?





I've been reading through the struts-example-application. It works perfect. The checkbox is allways set correct, even if the Form-Bean would say not checked by default. Sorry I know, that sometimes I ask stuped questions but:


Who tells the Checkbox if it should be checked or not?


Subscription.jsp



 tr
 th align=right
 bean:message key=prompt.autoConnect/
 /th
 td align=left
 html:checkbox property=autoConnect/

I thougt it would be the Form-Bean that would have some logic implemented. But i cant find nothing.



SubscriptionForm

columns?? Here is a code snippet:

 logic:iterate id=facility scope=session name=surveyForm

  bean:write name=facility property=description/
  html:checkbox name=facility property=state/

/logic:iterate

This prints everything in one long column. Is there a html thing I can use??

Title: AW: Who tells the Checkbox if it should be checked or not?





Thanks for your Answer. Can you precise what boolean value you mean? ( Do you men 'private boolean autoConnect = false;' in subscriptionForm?) 

But there's one thin I don't understand:


In the struts-example I choose
'Edit your user registration profile' and then I click on a profile I want to edit.


If in a previous session a had checked 'Auto Connect' then it still cheched (that is absolutly correct) 
But the boolean value autoConnect = false in subscriptionForm is set to false. So where does 'checked' the come from?


Thanks for your time

struts portal?

Hi, 

quick question, is there any struts or apache sub-project to provide
'portal-like' functionality?  basic functionality for users to select
components from a default list that they want to see in their home page.

Our current app is in struts and we'd like to avoid adding more new
technologies if possible.

when to use Struts custom tags

2001-09-24 Thread Adam Smith



I would be very interested in hearing people's views about when to use and
not to use the Struts custom tags for creating HTML. I am building an
application that I eventually want to release open source to an audience
that may only know HTML (and that is all I want them to have to know).

I can see where simple pages can be made simpler by the use of these tags,
but I can also see where it would quickly require a more in-depth knowledge
of how to use the tags, and about any idiosyncracies using the tags, and so,
put more of a burden on someone trying to customize the pages who only knows
HTML.

Also, I have another application in which I am thinking of having the output
be XHTML, initially going to HTML browsers. I am not sure that the final
output of the Struts custom tags would be backward compatible with HTML
browsers and parsable by XML browsers. (I have just started playing with the
custom tags.)

Thanks for any insight you can give.

Does anyone have any information on installing Struts and/or Sample Apps on
WS 4.0 Advanced Enterprise (AES) on a NT/2000 platform?  This is my first
experience with struts (and WS 4.0 for that matter!) and I am not having
much luck.  

I have tried to extract what I could from the Struts / WS 3.5x instructions,
but still no luck (and the deploy process seems to be considerably different
between these Websphere versions).

I can get the basic index.jsp pages to load in the samples, but after I try
any form action it seems like it does not know where to post, and just
returns a page not found error.

Any help is greatly appreciated!

Maybe it doesn't sound important, but a tooltip gives a plus to the

 Interestingly, in the HTML 4.01 Transitional DTD, the type of the 'align'
 attribute on the INPUT tag is 'IAlign'. This is the alignment type
 specified for images, so it would seem that it wasn't intended to be used
 for text. However, if browsers know what to do with it for text, and
people
 want to be able to use it that way, I have no problem with that.

Struts - XML - XSL

Hi, 


I'm involved in 
a project that use struts. I have a question to get some advice from you. The 
application want to separate clearly layout from the logic. The team manager 
want us to use XML, XSL to build html pages. But I don't see clearly how to mix 
all that. I have beans that do SQL query and return an iterator with the data, I 
suppose my controller servlet must call the beans and give the jsp access to 
this iterator. My JSP page will dynamically build XML file, but i don't know how 
to call the transformation of the XML data with a XSL file to build my final 
html layout. 

Can you help me

html:option value=overriden_valuetrue_i18n_value/html:option ?

2001-09-24 Thread Ken'ichi Unnai



Hi All, 

I'm building a small select.jsp - ReceiveServlet - result.jsp
test webapp.

As I went further, I found I have one problem for select option
value for foreign chars.

in select.jsp:
-
  html:form action=/select
   html:select property=color
html:option value=?jpLangValueForWhite? key=option1/
html:option value=?jpLangValueForBlue? key=option2/
html:option value=?jpLangValueForGray? key=option3/
   /html:select
   html:submitbean:message key=submit//html:submit
  /html:form 
-

What I want to do is avoid hardcoding the value of each option...
One thing that seems odd to me is why html:option has separate 
value  option attributes. I would appreciate if 

html:option value=white
 bean:message key=option1/
/html:option 

Then the value is overriden and it become the one from 
MessageResource property (in this example, option1 value) ...

There maybe some workaround if I use options tag but
that requires for Actin bean to have hardcoded array values.

Could anyone please point me out how to do it, making use of
MessageResource property without hardcoding Action bean?


Many thanks,
Ken

RE: Struts and XML

2001-09-24 Thread Kevin Jones


 It's not a Struts issue, just conflicts between parser versions.

Why? If I have Xerces in the struts directory then Struts should pick that
up ahead of Crimson in the common/lib directory. Assuming Struts is using
JAXP then there should be no dependency on the parser class names at all. I
have other applications that use Xerces and I haven't needed to touch the
common/lib directory xerces.jar lives in WEB-INF/lib, alongside crimson.jar
and jaxp.jar in common/lib and the application works fine.

I've been down this path of classloader problems before on Tomcat (with
Craig) and, until I installed Struts everything was working.

 The configuration mentioned is a documentated alternative for Tomcat.
 Many applications need Xerces available this way.

Agreed - but I shouldn't have to. Let's say, for example, that my ISP uses
Tomcat 'out of the box' and I install an application that uses Xerces, I
wouldn't expect (or want) the ISP to replace crimon/jaxp with Xerces. I want

one option is to use the xsl-taglib

Form layout not specified until runtime...

2001-09-24 Thread Jonas Bonér

Title: Form layout not specified until runtime...






Hi everyone.


We am building an extremely database driven system where everything (the JSP layout for example) 
is suppose to be dynamically generated in runtime. 
For example. We do not know in advance how many input fields we are going to present to the user.
This means that it is not possible to define a XXXForm JavaBean that has exactly these input fields.


Is there a way to meet these demands but still be able to use Struts?


Regards.

Title: AW: AW: Who tells the Checkbox if it should be checked or not?





As I understand it, value=yes ist the value that will be transmitted if the checkbox is checked. But it does not check the checkbox. I guess that there is no other solution than populating the Form-Bean in an Action-Servlet.

 Agreed - but I shouldn't have to. Let's say, for example, that my ISP uses

 wouldn't expect (or want) the ISP to replace crimon/jaxp with
 Xerces. I want

 Why? If I have Xerces in the struts directory then Struts should pick that
 up ahead of Crimson in the common/lib directory. Assuming Struts is using
 JAXP then there should be no dependency on the parser class names
 at all. I
 have other applications that use Xerces and I haven't needed to touch the
 common/lib directory xerces.jar lives in WEB-INF/lib, alongside
 crimson.jar
 and jaxp.jar in common/lib and the application works fine.

 I've been down this path of classloader problems before on Tomcat (with

security question

2001-09-24 Thread Jonathan M Crater


i'm using weblogic 5.1, which does not allow RequestDispatching to JSPs underneath 
WEB-INF.  so i'm stuck keeping my JSPs outside WEB-INF.  as a result,
i have to secure requests to both JSPs and actions.  securing the actions is just a 
matter of sub-classing ActionServlet and providing logic to check for
certain secured paths.  the problem is i don't want to repeat the logic in the 
JSPs--either through a tag library or otherwise.  does anyone have any
suggestions as to how best to prevent a situation where a user requests a JSP page 
directly when it should have gone through the sub-classed
ActionServlet?  i was thinking of just setting a request parameter for each request as 
it passes through the ActionServlet.  that way, in the JSP i can
just test for that value to determine whether the request went through the proper 
channel.  if not, i can redirect to an error page.

thoughts?  suggestions?

RE: Struts - XML - XSL

2001-09-24 Thread Ravindran Ramaiah


Following are the procedures that can used to apply the style sheet


Once we have already parsed the XML document, the getDocument method from
the parser instance (e.g. DOMParser) should return  an object of type
Document (which is actually a DOM representation of the XML). This will be
the starting point.

To apply the XSLT transformation, you perform the following steps:

1.  Create a DOMSource object and implicitly cast it to a SAX InputSource
object. The constructor takes in the Document object as a parameter.

InputSource source = new DOMSource(document);

2.  Instantiate a StyleGenerator object and pass the fully-qualified class
names of the XML and XSL parsers you want to use.

StyleGenerator stylegen = new StyleGenerator(Consts.SOURCEDOC_PARSER,
Consts.STYLESHEET_PARSER);

Where:
SOURCEDOC_PARSERcom.sengen.utils.DOMParserExtension
STYLESHEET_PARSER   org.apache.xerces.parsers.SAXParser

You can plug-in any DOM / SAX compliant parser you like. In this case we are
using two different parsers: a DOM parser for the XML and a SAX parser for
the XSL. The setup does not have to be this way. This is also the reason why
we have to implicitly casting in step one.

3. Lastly, call the StyleGenerator's applyStylesheet method. Originally, it
only deals with filenames but I overloaded it to accomodate InputSource and
streams. The resulting or transformed XML document is either written to a
file or returned as a byte stream.

public void applyStylesheet(String sourceFileName, String styleFileName,
String outputFileName) throws Exception
public ByteArrayOutputStream applyStylesheet(String sourceFileName, String
styleFileName) throws Exception
public void applyStylesheet(InputSource sourceInput, String styleFileName,
String outputFileName) throws Exception
public ByteArrayOutputStream applyStylesheet(InputSource sourceInput, String
styleFileName) throws Exception

Where:
sourceFileName  XML filename
styleFileName   XSL filename ** 
outputFileName  filename of the resulting (transformed) XML
sourceInput InputSource object created in step 1


** any type of stylesheet like XSL-2-HTML, XSL-2-FO,  XSL-2-whatever


-lines 3 and 4 correspond to steps 1 and 2 above.
-In line 7, he used the fourth version of the applyStylesheet method and
converted the byte array to a
string. This string is now the HTML transformation of the XML document.

1.  public String getPresentation() {
2.  
3.  InputSource source = new DOMSource(getDocument());
4.  StyleGenerator stylegen = new
StyleGenerator(KmpPdfgenConsts.SOURCEDOC_PARSER,KmpPdfgenConsts.STYLESHEET_P
ARSER);
5.  
6.  try {
7.  return
stylegen.applyStylesheet(source,getStylesheet()).toString();
8.  } catch(Exception e){
9.  //
10. }
11. 
12. return ;
13. }



Hope this helps.

Thanks,
Ravi

Generic pooling vs Poolman

2001-09-24 Thread Craig_Reichenbach



Hi, I created a basic Struts prototype web application that creates, edits,
and searches for users.  I then used Microsoft Web Application Stres Tool
(WAST) to test the performance of the Generic pool vs. Poolman connection
pooling.  I am using an Oracle DB (8.1.6). WAST logs into the app, searches
for a user, editsthe user, and logs out using 1 thread for 1 minute.
Connections were gotten in the Action servlets and passed to DB methods
like so:

Example:
conn= DBUtil.getConnection();
user  = DBUtil.validateUser( conn, username, password );

All connections, ResultSets, Statements, etc. are closed in finally blocks.

When testing the app using Poolman, the app performs fine.  When using the
generic pooling from struts, the application makes it until there are under
10 seconds remaining and begins throwing the following SQL exception:

java.sql.SQLException: ORA-01000: maximum open cursors exceeded

Re: link with dynamic page attribute

2001-09-24 Thread Matt Raible


You cannot next tags as you are trying to do.

My advice would be to make a forward in your struts-config.xml file that is:

forward name=editServiceReport path=/ServiceReport.do?operation=delete /

Then in your jsp page, you can code your link using a regular a href tag:

a href=html:rewrite forward=editServiceReport
/operationActivityId=bean:write name=activity property=id/link
text/a

This has worked for me.

Re: Generic pooling vs Poolman


Personally, I would strongly recommend that people use Poolman or the
equivalent in production applications. 

It's also possible that the generic connection pool will be deprecated
at some point, once a similar package becomes available through the
commons, and it becomes easier to hook new services up to Struts using
Oleg's ServiceManager. (The connection pool debacle is why we setup the
commons in the first place ;-0)

I often have misgivings about the GenericPool being part of the Struts
distribution, since it encourages people to tie the HTTP layer with the
resource layer. What I like about Poolman is that I can setup a
ConnectionPool class that returns the connection, without tying it to
the ServletContext in any way. 

import java.sql.Connection;
import java.sql.SQLException;
import javax.sql.DataSource;
import com.codestudio.sql.PoolMan;

public final class ConnectionPool {

/**
 * An exception message to throw if datasource is null.
 */
public static final String DATASOURCE_ERROR = Connection pool  +
not available. Check your poolman.xml config, and be sure  +
 you are using a valid dbname parameter (use dbname, not
jndiName);

/**
 * The application scope attribute under which our JNDI datasource
 * is stored.
 */
public static final String JNDI_DATASOURCE_KEY = articles;

/**
 * Returns a JDBC connection from a connection pool or other
 * resource, to be used and closed promptly.
 * p
 * @returns JDBC connection from resource layer.
 * @exception SQLException on SQL or other errors. May wrap other
 * exceptions depending on implementation. Will not return null.
 */
public static final Connection getConnection() throws SQLException {
DataSource ds = PoolMan.findDataSource(JNDI_DATASOURCE_KEY);
if (ds==null)
throw new SQLException(DATASOURCE_ERROR);
return(ds.getConnection());
}

RE: link with dynamic page attribute

2001-09-24 Thread Martin, Margaret


Antonio -
Unfortunately you cannot nest tags... you'll have to resort to a scriptlet
in this case:
html:link
page=/ServiceReport.do?operation=deleteoperationActivityId=%=activity.get
Id()%/
This seems to be something that everyone intuitively wants to do - hopefully
the capability will be added in a later jsp spec...

a second option is to put all of the parameters in a map (just as an
illustration):
% HashMap requestParamMapBean = new HashMap();
requestParamMapBean.put(operation, delete);
requestParamMapBean.put(operationActivityId, activity.getId());
%

html:link page=/ServiceReport.do name = requestParamMapBean/

Hope this helps -

Subject: link with dynamic page attribute


Hi,

i'm new to Struts and i'm already working on a project that takes advantage
of it.

The problem is: i'm trying to put a link, and the page attribute depends
upon the value of a bean defined by an iterate tag.

something like:

html:link
page=/ServiceReport.do?operation=deleteoperationActivityId=bean:getProper
ty name=activity property=id//

the error is:

org.apache.jasper.compiler.ParseException:

activity has no value

Does anybody have a clue?

how to capture html

2001-09-24 Thread Brian K. Buckley


Is there a good way to capture the output from a snippet of jsp into a
String variable that can be reused multiple times in a page?

- Brian

As a simple example, if one needed to have the line:

trth align='left' Name/thtd align='right' html:text
property='name'//td/tr

appear in several places, how can one set a String namerow so that the line
can be redisplayed by saying %=namerow% instead of repeating the whole
snippet?  Note that the snippet includes a custom tag.

Re: java.lang.NoClassDefFoundError: org/apache/struts/action/ActionFo rm

2001-09-24 Thread Peter Pilgrim




YES! I fixed the problem because I changed the startup.sh tomcat script
previously before Struts to include various jars. I should n't have done that.
but copied the proprietary jars in WEB-INF/classes instead. In fact
the Tomcat 3.3 blanks the CLASSPATH and sets only libraries that
appear under $TOMCAT_HOME/common/lib etc. In the older Tomcat 3.2
release this did not  happen, and probably the cause of many class not found
exceptions.

Moral: upgrade to Tomcat 3.3 and move out all project specifics jars from
$TOMCAT_HOME/common/lib.  into WEB-INF/lib. If you want tom use updated
Xerces PArser then you should copy the xerces.jar into $TOMCAT_HOME/common/lib

Moral:Check your classpaths.

Re: security question


If all the JSP's are behind Actions, the problem is mitigated since the
names of the JSPs are not revealed on the address bar, only the Action
shows. 

One idea would be to generate a request token for each request that
comes through the Action. That could be a dual use features, since you
could use the same token to watch for duplicate submits. You might also
put expects check at the top of the JSPs that use any other attribute
in the request, and redirect them to the Action when the attribute is
missing. That documents what the JSP requires, and provides QA on top of
security.

Re: link with dynamic page attribute


Nesting custom tags that way is not allowed by the specification. 

The html:link tag has special properties for assembling hyperlinks from
other beans. It can also accept a map when multiple parameters are
needed. 

http://jakarta.apache.org/struts/struts-html.html#link

Personally, I avoid using the page= property, and like to use only
forward= instead. That way everything is documented in the configuration
file.

Not really. The only way I know, is to enclose the snippet into a method
with a variable called out. HTML in JSP will be translated into

out.print();

newbe: radio button iteration


Hi, I am trying to iterate through a bean and populate a list of radio
buttons. I pass an entity object (en) to a page. The entity object has a
number and name parameter. I want to create a list of radio buttons all with
the same name but the values being the entity number.
For example:

 input type=radio name=entityNumber value=123 1996 DODGE DAKOTA
PICK-UP TRUCK
 input type=radio name=entityNumber value=234 1996 DODGE BUS

I have tried the following:

logic:iterate id=en name=entitySearchList scope=request 
TR
  TD CLASS=TD_Border
  html:radio name=en property=entityNumber value=bean:write name=en
property=entityNumber /   /
  /TD

  TD CLASS=TD_Border
bean:write name=en property=entityName /
  /TD

/logic:iterate

The above obviously does not work. I would appreciate it if someone could
lend me a hand.

taken those 3 into account, I think you really do need serious help. Not
being funny, but usually people either working with other experienced
developers or simply with a few years of Java and some EJB exposure should
be endevouring with such a task.

 1) Is this the appropriate way to call EJBS (in an action class)?? 

yes, it's fine to call EJB's from the action class.

 2) How do I get what is returned from the EJB back into my actionform
bean?

you (presumably) will get back an object/collection of data back from the
EJB. you can parse it and populatev the form with it/add to the request -
then pull it out in the jsp with the struts cust tags.


 3) If I want a list of matching customers retruned...what is the best
format
 for these to be returned from the EJB so that I can
 forward to another jsp and show them..  Currently the EJB is returning a
 string.

see above. To reiterate, put it an Collection (ArrayList for example) or in
a custom Object (JavaBean.. not Enterprise Java Bean!!)

as far as I know not of Struts/EJB. Weblogic comes with a good load of

Reusable/composable Struts components?

2001-09-24 Thread Gary Johnston


How do folks generally approach building reusable or composable Struts
components?  I'm thinking about a situation where I'd like to define a
reusable sequence (not necessarily linear) of Struts JSPs/actions that can
be invoked as kind of a black box from some other part of the Struts
application and can be told where to transfer control to when done.

For example, let's say I'm building a Struts application that consists of
several possible services an end-user might want to use, so I have a main
menu page that has a link for each service (like, say, .../service1.do,
.../service2.do, etc.).  Now, let's say that each service requires that
the user be logged on, so each corresponding Action subclass' perform(...)
method needs to check the logon state of the current user and, if they're
not already logged on, route them to the logon sequence.  I'd like to factor
out that whole mess into a reusable ensure the user is logged on sequence.
I'd like to be able to invoke it from any Action that needs it, have it do
its thing, and then proceed on to the main functionality of the service.

Problem is, Struts forwards are essentially absolute gotos (albeit with a
level of indirection through the Struts config. file).  When I am coding,
say, the last action in my ensure the user is logged on sequence, I have
to return a forward that essentially says where to go next.  I'd rather be
able to return a forward (or code something else) that means, basically, go
to wherever whatever invoke me wanted me to go when I'm done.  Obviously,
this would require whatever invoked it to somehow record that information
when/before it did so.

An ad hoc solution is possible for any specific one-off situation, of
course,  but I'm interested in a more general solution (which would need to
involve a stack of some kind to support arbitrary nesting).  I can think of
a few possible general approaches, but surely others have had to deal with
this issue.  What approach did you use and how do you like it?

BTW, it seems like it may be that the proposed workflow support will start
to address this issue, but I'm wondering what people are doing today.

transaction control mechanism (multi submit prevention)

2001-09-24 Thread stephaneg

Hello all.

I have aquestion regarding the postings
explaining how to correctly use the transaction control mechanism provided
within struts. Most postings mention that struts will forward you to an error
page however I haven't been able to find any mention on how to then forward to a verification screen.

Therefore, let's say that rather than forward to an
error pageI would prefer it not forward at all and just remain idle
waiting for the form submission to be processed and the be forwarded to a
verification page. Another viable option for us is that we forward it to an
error page, and that once the submission processing is completed it goes on to
the verification page, but the issue here is that I don't believe it's possible
to push a page, and even if it was, how would we determine when the processing
is completed without javascript in the jsp.

Any advice you could give me would be very
appreciated as I haven't been able to find a proper solution. Also, as another
requirement, all this is to be done without the help of any javascript (which by
the postings all the work seems to be done in the action class anyways with the
help of the token methods in the Action class).

Regarding my first issue, forward to nowhere, I did
notice in the ActionAPI that the perform method when returned null should
ignore the forward ("or
null if the response has
already been completed"), however when I implement this I find this is not the
case. Therefore I'm not sure if I'm reading more into it then I
should...

Thank you,Stephane Grenier

struts architecture question.


Hi,

I am trying to figure out if I have properly designed my classes.

I have a class that extends ActionServlet. The only reason it does that is
because all my web apps need a couple of generic objects in the application
session before anyone can use the applications.

So I overrode the doGet and doPost and init() methods. Examples are below:

public void init() throws javax.servlet.ServletException
  {
super.init();
//do Some Configuration;
  }

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws java.io.IOException, javax.servlet.ServletException
  {
HttpSession session= request.getSession(true);

*/
if(session.getAttribute(Constants.SERVLET_CONFIG)==null)
  {
session.setAttribute(Constants.SERVLET_CONFIG, configSettings);
  }

/**
* place the rdserver object in the session
*/
if((session.getAttribute(Constants.RDSERVER))==null)
  {
rdServer server=new rdServer(strHost, strPort);
session.setAttribute(Constants.RDSERVER,server);
  }

  super.doGet( request,  response);
  }

I don't know what is wrong with the above it just looks wrong. And, when I
start this app in tomcat I can see that the web app is being parsed and
loaded twice.

Any design tips, comments on the above are appreciated.

Alex

Can you comment on this design idea?


Hi,

hopefully someone can comment on an idea I have.

I have a VB backend that I talk to via a socket to handle db access. When a
connection is made to the back end I put a Boolean value of TRUE under the
active key in the application session. If for whatever reason the VB
backend goes down I get the key active and set it to FALSE. I created a
tag that as the user goes from page to page it checks this key and if it is
active it continues displaying the page and if it is not it takes the user
to a generic, back end down page.

A problem I found is that a user could be on a page and submit data to a
servlet. If the backend has gone down while the user has been on a page, the
servlet will not know about it and attempt to do some work. I do not want
this to happen. I want a similar set-up that I have for the pages for the
servlet.

I was thinking of overriding the doGet and Post methods of the ActionServlet
to check if the active key is true. If it is continue passing the request
to the servlets if it is not then send them to a generic, back end not
available page.

Something like this:

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws java.io.IOException, javax.servlet.ServletException
  {
String errorPage=/serverNotAvailable.jsp;
if(key)
{
//do usual work
}
else
{
RequestDispatcher disp=new request.getRequestDispatcher(errorPage);
disp.forward(request,response);
}

super.doGet(request, response);

any comments are appreciated.

 If you want the items to be in a specific order then you need to store

 You are getting the InvoiceLineItems out of order b/c you are storing

the

 ordering, you need to use a Collection that implements the List interface
 (ArrayList, LinkedList)  You could use a TreeMap or SortedMap, but these
 would incur more overhead for your application than using a collection

RE: Can you comment on this design idea?

2001-09-24 Thread Hans Gilde


Alex,

You probably want a connection pool. Your code in an Action class (or
wherever) would be something like:

MyConnection MyConnectionObject;

try {
//get the connection from the pool
MyConnectionObject = MyConnection.getInstance();
//do your stuff
} catch (MyConnectionInvalidException e) {
//error
} catch (MyConnectonInterruptedException e) {
//another error
} finally {
//release the connection back to the pool
MyConnection.releaseInstance(MyConnectionObject);
}

Where MyConnection.getInstance() and releaseInstance are public static
methods of MyConnection; they check the connection before returning it.
There are a couple of open source connection pools that help here. This
technique would be directly portable between a servlet and a GUI
application. It requires a ping before each connection attempt but is
probably worth the overhead.

If you're open to changing the architecture... Why not use SOAP calls to COM
objects running in MTS? There's a more overhead in each invocation but you
get to use neat new technology.

populating an ActionForm using BeanUtils.populate

2001-09-24 Thread David Boardman


I am attempting to populate an ActionForm from a ValueObject using
BeanUtils.populate().  The ActionForm has all of the appropriately named
setter methods and attributes, and the ValueObject returns a map with keys
corresponding to the attribute names on the ActionForm.  The problem is that
when I place the value of the ValueObject's id attribute (a Long) in the
map, the populate method fails with the following exception:

java.lang.IllegalArgumentException: argument type mismatch
at java.lang.reflect.Method.invoke(Native Method)
at
org.apache.commons.beanutils.PropertyUtils.setSimpleProperty(PropertyUtils.j

at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:506)
at
com.integral7.web.durango.CandidateDetailAction.perform(CandidateDetailActio
n.java:118)

It appears that BeanUtils.populate() requires the values in the map to be of
type String or String[], is this true?  If so, should I be converting the id
to a String in the ValueObject.toMap() method?

Thanks,

Dave

passing reference from page to page

I have a search page with some input fields. The values 
the user inputs are stored in my search form bean in the request scope called 
SearchBean. If the search returns 0 results, I send them to a message page

SearchBean?

Re: Reusable/composable Struts components?


People typically subclass the Action or the ActionServlet. 

Subclassing the Action can be advantageous when some Actions require a
login and others do not. The protected Actions can share a common
subclass that forward to login when someone is not logged in.

The Logged-In ancestor class might do something like this:

// -- isLoggedOn? 
HttpSession session = request.getSession();
Bean logonBean = (Bean)
session.getAttribute(Constants.LOGON_KEY);
if ((logonBean == null) {
session.setAttribute(Constants.ROUTE_TO_KEY,request);
return (mapping.findForward(logon));
}

// -- isCancelled?
if (isCancelled(request))
return (mapping.findForward(cancel));

return null;

And a subclass requiring login would do something like:

// -- Check Login
ActionForward actionForward =
super.perform(mapping,form,request,response);
if (actionForward!=null) return actionForward;

In this example, a logon bean has been placed in the user's session.
This could be any sort of bean, and not linked to the HTTP layer, and
actually be a business logic, or application logic bean. 

A similar approach would be to place service beans in the application
context, and access them through special methods in your application's
ancestor Action. This way, the components are not only reusable between
Struts Actions, but also in other environments (e.g. Swing, another
framework). The Action should simply be an adapter between the HTTP
layer and your components. This will become even easier to do as
development progresses on Oleg's ServiceManager. 

The service bean approach presumes that the (multi-threaded) service
beans do not store any data, and whatever data is required is passed to
them from the Action. This is a place where the workflow proposal's
Context objects could be useful.

 How do folks generally approach building reusable or composable Struts
 components?  I'm thinking about a situation where I'd like to define a
 reusable sequence (not necessarily linear) of Struts JSPs/actions that can
 be invoked as kind of a black box from some other part of the Struts
 application and can be told where to transfer control to when done.
 
 For example, let's say I'm building a Struts application that consists of
 several possible services an end-user might want to use, so I have a main
 menu page that has a link for each service (like, say, .../service1.do,
 .../service2.do, etc.).  Now, let's say that each service requires that
 the user be logged on, so each corresponding Action subclass' perform(...)
 method needs to check the logon state of the current user and, if they're
 not already logged on, route them to the logon sequence.  I'd like to factor
 out that whole mess into a reusable ensure the user is logged on sequence.
 I'd like to be able to invoke it from any Action that needs it, have it do
 its thing, and then proceed on to the main functionality of the service.
 
 Problem is, Struts forwards are essentially absolute gotos (albeit with a
 level of indirection through the Struts config. file).  When I am coding,
 say, the last action in my ensure the user is logged on sequence, I have
 to return a forward that essentially says where to go next.  I'd rather be
 able to return a forward (or code something else) that means, basically, go
 to wherever whatever invoke me wanted me to go when I'm done.  Obviously,
 this would require whatever invoked it to somehow record that information
 when/before it did so.
 
 An ad hoc solution is possible for any specific one-off situation, of
 course,  but I'm interested in a more general solution (which would need to
 involve a stack of some kind to support arbitrary nesting).  I can think of
 a few possible general approaches, but surely others have had to deal with
 this issue.  What approach did you use and how do you like it?
 
 BTW, it seems like it may be that the proposed workflow support will start
 to address this issue, but I'm wondering what people are doing today.

validate() fails to re-populate the html:form

2001-09-24 Thread Blessing, Jeffrey


I've just recently read the entire thread on this issue posted
last Wed 9/19/01 and still have the following problem:

When the validate() method of my form bean returns a non-
empty ActionErrors list, struts fails to re-populate the form
fields with the text that was submitted successfully.  I've
checked the following:

In ApplicationResources.properties:

errors.header=ul
errors.footer=/ulhr

In struts-config:
==
actionpath=/saveTriage
   type=org.apache.struts.webapp.example.SaveTriageAction
   name=triageForm
  scope=request
  input=/triage.jsp
   validate=true
/action

The errors list *is* reported successfully on the input JSP page, however.
This is the only JSP page involved (no wizard like series of JSP pages).
I tried the fix suggested in the list, of changing the scope to session,
and
the app throws the following exception:
No bean found under attribute key triageForm

I've based this app on the struts-example app, as it appears that everyone
else is also doing.

What next?!

Did you try to store the reference in the 
session?

  Subject: passing reference from page to 
  page

  I have a search page with some input fields. The 
  values the user inputs are stored in my search form bean in the request scope 
  called SearchBean. If the search returns 0 results, I send them to a 
  message page saying "0 results found" with a link that will take the user back 
  to the search page with the original search criteria filled in. 
  Currently, I have hidden fields on the message page to pass around the 
  original search criteria. Is there a way to pass a reference to the 
  SearchBean from page to page so that I wouldn't have to use the hidden fields 
  for every attribute in the SearchBean?
