RE: Problem with loss form (session scope)
Hmm. That does sound rather odd! Like you say, should not be like that. :-( Only thing I can thing of here is: Is it the same session? (grasping at straws now!) Try println/logging the sessionId from the action and see if its still the same as first time through. -Original Message- From: Betty Koon [mailto:[EMAIL PROTECTED] Sent: Friday, 27 February 2004 15:39 To: 'Struts Users Mailing List'; [EMAIL PROTECTED] Subject: RE: Problem with loss form (session scope) I am sorry. I only have 1 action map to this form. So, I guess the name doesn't matter in this case. Basically, what I am saying is the first time I hit this action, the form constrctor will get called but the 2nd time the action get called, this shouldn't happen, but it does.

Is it the same name for the form in both actions mappings, and do both these action mappings specify the scope to be session? My suspicion is that the problem is that struts is trying to find the form under a different key in the second action - but is this second action actually the same action as the first or different as I am assuming? btw: have you gone and looked at the struts source code for the request processor and request utils class to see what it is actually doing? (Tracing through with a debugger can be quite enlightening). One of the common attitudes in open source is that the source is the best reference and I certainly found this the case when I was first learning struts :-) -Original Message- From: Betty Koon [mailto:[EMAIL PROTECTED] Sent: Friday, 27 February 2004 15:10 To: 'Struts Users Mailing List'; [EMAIL PROTECTED] Subject: RE: Problem with loss form (session scope) I specify my own name in the struts config.

To me this implies your getting a form not in session scope (i.e. request) and saving it yourself in session scope. If that is the case - then maybe thats your problem - if the struts-config.xml says its request, thats where struts will look for it and, if it doesn't exist, it'll set a new one up in request scope (even if you already have one under the same name in session). If I've got it wrong, then maybe you could explain further. I'm also not clear whether your finding out your form has been 'wiped' as soon as you get into your action and before you set it up as session scope or after that when you get to your detail screen.

RE: Struts Workflow
Hi, I don't think building a real workflow would be that simple.I mean the workflow must be built in the framework, the actions being just configured to use it. And why reinvent the wheel when there is already a solution :-)) Have a look at http://www.livinglogic.de/Struts/ We used it in our project and found that it satisfies most of the requirements. I am not sure what exactly is your requirement.But the above mentioned extension satisfies all workflow requirements.And I am in the process of refactoring it so that it provides more extension points for customization. 1.It provides workflow scope.So if you define a group of actions belonging to a workflow, they have their own workflow scope.The objects in this scope are available only for the duration of the workflow scope.If user jumps out of workflow,the workflow scope is cleared. 2.You can define modal dialogue box like screens, where user can be forced to complete a workflow/cancel it explicitly before he can jump workflow. And the best part is,you do not need any code change.All of this is taken care by the workflow extension.You only have to configure your action mappings to use workflow. Have a look at the demo application on the web site. Also the test application is another replace where you can see how the extension can be used in a real world application. I am in the process of transferring this application to sourceforge.Just transferred all source code to sourceforge cvs yesterday :-)). Have a look at the extension and let me know if you still have any questions. HTH.

if you're scoping to request you'll need a while loop in your

public Address getAddress(int index) {
while(index = addressList.size() ) {

Where are you populating ActionForm Object from the results from service layer? In Action class only right? Which you know very well for which JSP page it will be applicable. True, but having one well-defined interface between the two (an ActionForm) is preferable to having a handful of poorly-defined interfaces between them (an ActionForm + stuffing a bunch of stuff into the request). Also is it easy to populate all what you need in ActionForm? How one can populate resultset in action form which will automatically get populated in html table.. Yes, call myActionForm.setResults(results) instead of request.setAttribute(results, results). This may seem like a minor point (and it is admittedly a simple example), but maintaining complex pages with a lot of structured data behind them gets difficult when you have to pull a bunch of stuff out of the request with no structure defined between the items you are pulling. Using the ActionForm as the root of your data structure is a simple rule to follow that 'scales up' (with data structure complexity) much better than request-stuffing. -Max - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I created a plugin and in its init method I do the following moduleConfig.addForwardConfig(new ForwardConfig(mypath,myurl,true)); when I do in the action return mapping.findForward(mypath); it gives me a classcast exception java.lang.ClassCastException at org.apache.struts.action.ActionMapping.findForward(ActionMapping.java:151) at com.silkroad.srm3.Login.execute(Login.java:42) When I did some debugging found out that the exception is happening because of the following code return ((ActionForward) config); in org.apache.struts.action.ActionMapping.java line 151 config contains a forward defined by me and has type org.apache.struts.config.ForwardConfig what should I do? are there any other ways dinamically defining global forwards?

Re: microsoft sqlserver driver struts
It gets thrown when the application starts, but then more errors occur as there are several servlets which load upon start-up - the data source is null at this point (NullPointerException's are being thrown) and so the errors are thrown when these classes try to access the database. - Original Message - From: Mark Lowe [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, February 27, 2004 11:29 AM Subject: Re: microsoft sqlserver driver struts Does the error get thrown when you attempt to access the data source or at startup?

Re: microsoft sqlserver driver struts
Can i see the bits of code in the servlets (non action servlets) at start up that retrieve the datasource? And an example from any actions. Also see the load on start up order as i imagine that the struts servlet needs to load before your servlets to be able to access the datasource.

SV: ArrayList in Form
Hi Shashank If I understand you correct, you want to modify the properties in an object within a Collection Do like this: logic:iterate id=rows name=theForm property=rows type=com.company.TheObject html:text name=rows property=firstName indexed=true / html:text name=rows property=lastName indexed=true / /logic:iterate There are 2 important things to remember: 1. id attribute in the iterate tag MUST have the same name as the property attribute in the iterate tag (rows) 2. you have to set the attribute indexed to true ( indexed=true ) Hope this wil help you Med venlig hilsen Claus Weng Madsen, Teamleder TELMORE A/S Carl Gustavsgade 3, 2630 Taastrup Telefon 70218700, Mobil 30242875 www.telmore.dk -Oprindelig meddelelse- Fra: Dixit, Shashank (Cognizant) [mailto:[EMAIL PROTECTED] Sendt: 27. februar 2004 10:17 Til: [EMAIL PROTECTED] Emne: ArrayList in Form Hello All I have a ArrayList in the form which contains a CustomObject TheROw.

Re: microsoft sqlserver driver struts
Mark, My problem is that I'm switching JDBC drivers - before I was using weblogic's JDBC driver for SQL Server and I've been using that for a long time now and never had any problems. Now I'm trying to ditch the weblogic driver and in its place use Microsoft's JDBC driver for SQLServer. Sorry, should've mentioned that before. I'm not sure that showing the code for getting the datasource is going to help because I'm assuming that this is not the problem - the problem is surely to do with the type of datasource. I had a similiarish problem trying to use an Oracle database - in the end the type of datasource was the problem and not how I retrieved it in my actions. Have you used Microsoft's SQL Server 2000 JDBC driver with struts before, and if so, what type of datasource do we use? Can't find anywhere that says anything about it. Cant be too difficult..

Bean:message in attribute causes non-matching extension tags error
Hello All,
I am trying to have text from my property file appear into one of the
attributes of an html select element. The code which I have written is
html:select property=destinationType onchange=
javascript:fnLocationBlur(); fnChangeZoomImage()
onfocus=fnSetFocus('0');window.status ='bean:message
key=select.destination.type/'; return true value =
'%=destinationType%'
html:option value=citycity/html:option
html:option value=statestate/html:option
html:option value=countrycountry/html:option
/html:select
However when invoke the jsp I get an exception
/jsp/WcNoNc/Query.jsp(575): Non-matching extension tags //[ null; Line:
575]
probably occurred due to an error in /jsp/WcNoNc/Query.jsp line 575:
/html:select
What am I doing wrong? How can I get the text from my property file into one
of the html attributes?
Thanks for your help in advance.
Regards,
Abhishek.

RE: Problem in nested tags- Very Urgent - Please Help
i'll try to use lazy list once i finish off my work
Eugh... We have all done it, but that is how botches get in to production code. People
usually get too busy to apply the 'proper' code, or something more important that
needs attention comes along.
2 years later someone comes along and has to rewrite a major part of the application
to compensate for the temporary fix :P
Welcome to the Software Industry.
btw that is not a personal slight on you :) just an observation of the industry as a
whole.

shirish posted this a few times.
if you're scoping to request you'll need a while loop in your
getFoo(int index) method
public class OrgManagementForm extends ActionForm {
private List addressList = new ArrayList();
public Address getAddress(int index) {
while(index = addressList.size() ) {
this.addressList.add( new Address() );
}
return (Address) addressList.get(index);
}
bla bla.
}
look like it could be your problem.

RE: Problem in nested tags- Very Urgent - Please Help
But using lazy initialization is simple...
See my earlier post...
I am resending my earlier mail to another user.Go through the sample code
and
ask me if u dont understand something.
The important portions are commented.Especially look at the jsps property
how
it is set and also the form bean.The property syntax i have used was for struts 1.0
..But with struts 1.1 , you can have a better cleaner syntax using nested tags.But I
have not used it...This works for 1.1 as well..
//Form Class
import java.util.ArrayList;
import java.util.List;
import org.apache.struts.action.ActionForm;
public class ExampleListForm extends ActionForm {
//A list of Emp beans
private List beanList = new ArrayList();
public List getBeanList(){
return beanList;
}
public void setBeanList(List list){
beanList = list;
}
//very imp.
//give indexed access to the beans
public Employee getEmployee(int index){
//very imp
//when a jsp is submited , then while auto populating the form,this will
ensure
that
// the form is populated properly.
while(index = beanList.size()){
beanList.add(new Employee());
}
return (Employee)beanList.get(index);
}
public void setEmployee(int index,Employee emp){
beanList.set(index,emp);
}
}
***
Bean class
public class Employee {
private String name;
private String salary;
/**
* Returns the name.
* @return String
*/
public String getName() {
return name;
}
/**
* Returns the salary.
* @return String
*/
public String getSalary() {
return salary;
}
/**
* Sets the name.
* @param name The name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* Sets the salary.
* @param salary The salary to set
*/
public void setSalary(String salary) {
this.salary = salary;
}
}
JSP
%@ page language=java%
%@ taglib uri=/WEB-INF/struts-html.tld prefix=html %
html:html
html:form action=/
logic:iterate id=bean name=exampleListForm property=beanList
indexId=i/
html:text name=exampleListForm property=%=\employee[\ + i
\].name\%
html:text name=exampleListForm property=%=\employee[\ + i
\].salary\%
/logic:iterate
/html:form
/html:html
Explanation:
See how the property is constructed.
html:text name=exampleListForm property=%=\employee[\ + i
\].name\%
So this will result in a parameter name employee[i].name in the http
request.So
when the jsp is rendered, this will be interpreted as
getEmployee[i].getName().And when the jsp is submitted , the same will be
interpreted as getEmployee[i].setName().And this will result in auto
population
of data in the form as u can see.
So check the indexed properties on the form as well.(Especially the
getEmployee(index i) proeprty with while loop.)
Hope this helps.
regards,
Shirish.

RE: servlet filters and authentication
Hi,
I checked out SecurityFilter yesterday, after Robert Taylors
recommendation, and have looked through a good bit of the source.
I'm probably going to use your package once i get this thing closer to
its final state. It looks like a great program.
I like to write my own lite versions of packages i use, if possible,
just to feel that i really know whats going on. I even did this with
struts, believe it or not. I wrote a struts lite that uses a controller,
action forms and actions, and an xml config file. I used it for a couple
of small projects, and now that i've got a handle on the basic idea, i
feel i can use the real Struts with more confidence. Right now
concentrating on becoming very familier with Struts, once i get that
down, in a couple of weeks i'll pop your Security Filter in.

I'm the primary author of the SecurityFilter project, and the filter
logic is a bit more complicated than the code that was posted. Even if
you decide not to use SecurityFilter, it is probably worth a look at the
doFilter() method.
Some issues that you will/may have to deal with:
1. Filter getting executed on forwards (depends on your container).
2. Sending the user back to the page they requested when the login
sequence was initiated (a key feature, IMO).
3. Keeping request parameters (both GET and POST) across the login
event.
4. Sending the user to an error page when the login fails.
5. Allowing login form and error page requests to be processed without
invoking the login sequence.
6. Knowing what to do / where to send the user if they authenticate
spontaneously (i.e. when they weren't sent to the login form by your
filter).
Basically, there's a lot of stuff to deal with even though it seems
simple at first. :-) If you can use container-managed security or
SecurityFilter, you'll probably save yourself some time that would
otherwise be spent dealing with these issues. It is worth investigating
the existing solutions before rolling your own.

Subject: servlet filters and authentication
Hello,
I'm configuring the skeleton of a multi module struts application, and i
would like use a filter for the authentication.
here is psuedojava (for easier reading) of the filter:
public final class AuthFilter implements Filter {
public void doFilter(request, response, chain)
session = request.getSession();
auth = session.getAttribute(authenticated);
if (auth == true) {
chain.doFilter(request, response);
return;
}
else {
dispatcher =
request.getRequestDispatcher(/WEB-INF/jsp/security/login.jsp);
dispatcher.forward (request, response);
return;
}
}
}
I've seen this skeleton suggested in several places on the web.
The question i have is this: After the user submits the login form,
the request will come through the filter, and since it has not yet
been authenticated, it will again forward to the login.jsp.
I've thought of a couple of ways to deal with this and
would like to get input on these and any other approaches.
1) set the mapping of the filter in web.xml in such a way that it
allows the login action through. maybe set all actions to have an
extension of .do except the login action, which has an extension of
.auth. I don't think this will work for me, because the multi module
support of Struts requires extension mapping. I guess i could write a
small serlvet that is not in the struts mapping but is in the same context
and have it mapped to *.auth
2) check within the above filter to see if the request is for the login
action, and if so allow it through. so the if statement above would be:
if (auth == true || req.getPath().equals(login.do))
Any comments on these ideas or approaches i haven't listed would be
greatly appreciated.

shirish posted this a few times.
if you're scoping to request you'll need a while loop in your
getFoo(int index) method
public class OrgManagementForm extends ActionForm {
private List addressList = new ArrayList();
public Address getAddress(int index) {
while(index = addressList.size() ) {
this.addressList.add( new Address() );
}
return (Address) addressList.get(index);
}
bla bla.
}
look like it could be your problem.

RE: [OT] JSP or Velocity
Having your JSP built using tiles, each (if necessary) having its own dynamic Tileaction is excellent. It offers so much flexibility, especially when its combined with JSTL. The only gripe I have is with JSTL and not having the ability to get map sizes. Its easy to code around this, but it would have been nice out of the box :P If you ask the JSP or velocity question on a list that has a good mix of both sets of users, then you are going to get a few biased opinions for either side. Try and figure out the requirements of what you want your application to do and would like it to be able to do in the future. Then see if either does not or, is unable to offer this feature list. That should make your decision a bit easier.

I am starting to develop an application using struts and have been
looking round the rest of the Jakarta project and came across the
Velocity project.
I was interested to see which which people recommended for a relative

After looking at velocity, I am certainly of the opinion that it adds no
value over
jsp2/jstl. It offers absolutely nothing that the jsp2/jstl combination
does not.
The only difference is that velocity is a bit more terse (if/else/end
instead of
c:choose/c:when/c:otherwise) and that it uses # instead of the .
It is important to note that I am talking about jsp2 and tomcat 5, not
the jsp1 in
tomcat 4.
A while back I looked in detail at the jsp/velocity comparison on the
velocity site.
There are several issues with the comparison. The person writing the
case study
was cleary biased towards velocity and had never even considered JSTL
(which
in all fairness may not have been available at that time). Looking at
the code
(both the velocity and jstl versions are below) I think that velocity
clearly had
an influence on the jsp2/jstl constructs.
The first thing I noticed was that the two pages do not do the same
thing.
The jsp turns off the session (the vm does not). The jsp stores
variables that
are never used which were factored out in the vm version. The vm version
is missing required code (for example, the repCode and urlEvent
variables
are never defined).
The jsp page is also *very* poorly written using scriptlets. You should
rarely need
to use scriptlets in jsp1/jstl pages, and I suspect with jsp2/jstl, you
will not ever
*need* to.
With struts, you do not need to use jsp:useBean tags either because
the controller
does that for you.
The jsp2/jstl version is a bit more verbose because it is based on xml
so you
cannot have things like if/else/end because they are unbalanced, but
other than
that, there are no significant differences.
After converting the page to use JSTL and eliminating ALL of the % %
stuff, we
get something more like this:

Yes, Velocity has been around for quite awhile now, and it was intended to
address many of the problems inherent in (older versions of) JSP.
Nowdays JSP (especially JSP2) coding techniques and technologies have rather
caught up with velocity. Your assesment that it doesnt add much value over
the EL capabilities in JSP2 is pretty much on the mark. Of course it wasnt
always this way and for a long time velocity was much nicer. (Still looks

Re: [OT] JSP or Velocity
Hi, I've used JSTL and velocity. Velocity is fast and a smart way to generate dynamic pages but it is not as comfortable as JSTL is. You have to implement many things which exist in JSTL and other taglibs already. If you use the macro stuff it will be easier but still a lot work to do.

Maven is not the official build mechanism for Struts, and there's no guarantee that it will become such in the 1.x line. On the other hand, if folks make Maven do everything the current Ant build does, it might. Of course, the fact that Maven still hasn't seen a full 1.0 release does lend some support with keeping Ant the official way. For the docs, the main thing would be to eliminate any need to maintain dual documentation while the Ant build is still the official build.

Manipulate page validation for ValidatorForm
Hi, I have the following problem; the page validation of the ValidatiorForm requires that the pages are ordered (e.g. a wizard-initalization) and performs validation for all pages = current page. If a page is undefined or 0, validation for all pages is performed. In my application I have an intialization that requires this functionality, but the pages I have are not ordered, making the validation of current page and all pages before invalid. What I do need is validation for page = current page and not the ones before. Is this somehow possible without loosing the normal (validation.xml entries) validation? I'm using struts version 1.1.

RE: Problem in nested tags- Very Urgent - Please Help
hi,
i'm trying to use hubert's (and shirish's) approach on request-scope, and as long as
the amount of rows are fixed it works well.
BUT now i have an additional feature on my page and that gives me headaches.
actionOne gets the rows from the dto-bean and initializes the jsp.
on the jsp-page with the form over the rows, i have an additional form where the user
can toggle through different versions of my db.
this form submits to actionOne where the action is supposed to fetch another set of
rows, according to the parameter given.
let's say: choose february 12th there are 12 rows to display, choose february 15th
there are 15 different rows, choose the next day there are 10 rows.
with this approach, starting with february 12th i get 12 rows. changing to february
15th i get the old 12 rows and the new 15 rows added to, going back to feb 12th i get
the old 27 rows and again the 12 rows from feb.12 added to and so on and on
is there a way to reinitialize the autopopulation method or even to temporarily
disable autopopulation on lists with nested properties?
any adwise or code snippets are warmly welcomed
take care

IIRC, you also need it in reset():
public class LazyListExampleForm extends ActionForm {
private List actionList;
public LazyListExampleForm () {
initLists();
}
public void reset(ActionMapping mapping,
HttpServletRequest request) {
super.reset(mapping, request);
initLists();

private void initLists() {
Factory factory = new Factory() {
public Object create() {
return new ActionListBean();
}
};
this.actionList = ListUtils.lazyList(new ArrayList(), factory);
}

if you're scoping to request you'll need a while loop in your
getFoo(int index) method
public class OrgManagementForm extends ActionForm {
private List addressList = new ArrayList();
public Address getAddress(int index) {
while(index = addressList.size() ) {
this.addressList.add( new Address() );
}
return (Address) addressList.get(index);
}
bla bla.

look like it could be your problem.

RE: Manipulate page validation for ValidatorForm
We had to do this for our last project; I had an ActionForm for each page
with validator bindings to validate input on each page. In the Actions, I
used the page's form to update a transaction bean in the session which I
in turn called a commit method on it to execute business logic (validate
product inventory/medical information/etc). The commit method then could
throw business exceptions which I bound to exception handlers.
I referred to it as conflict-resolution where your goal is a successful
commit of the transaction, but for any conflict, you resolve with a UI
page and separate action form to validate user's data. Any input validation
would be taken care of by each page's ActionForm.
ActionForward execute(..) throws Exception
{
TransactionSession tx = getTransaction(httpSession);
tx.setQuantity(new Integer(form.getQuantity()));
tx.commit()
return mapping.findForward(SUCCESS);

Subject: Manipulate page validation for ValidatorForm
Hi,
I have the following problem; the page validation of the ValidatiorForm
requires that the pages are ordered (e.g. a wizard-initalization) and
performs validation for all pages = current page. If a page is
undefined or 0, validation for all pages is performed.
In my application I have an intialization that requires this
functionality, but the pages I have are not ordered, making the
validation of current page and all pages before invalid. What I do need
is validation for page = current page and not the ones before.
Is this somehow possible without loosing the normal (validation.xml
entries) validation? I'm using struts version 1.1.
Thanks

RE: [OT] JSP or Velocity
Basically, i use velocity only for email templates and sometimes to generate
other kind of templates from one template where the use of XSLT is not
appropriate.
For web templates, that have more complex requirements, i prefer to use
taglibs. besides el makes life as easy as we may talk in velocity. In
velocity, to comprehend taglibs, you may have have to write lots of
velocimacro.
you may ask for another opinion on velocity-user list as well.

[EMAIL PROTECTED] 02/27/04 5:44 AM
I am starting to develop an application using struts and have been
looking round the rest of the Jakarta project and came across the
Velocity project.
I was interested to see which which people recommended for a relative
newbie
After looking at velocity, I am certainly of the opinion that it adds no
value over
jsp2/jstl. It offers absolutely nothing that the jsp2/jstl combination
does not.
The only difference is that velocity is a bit more terse (if/else/end
instead of
c:choose/c:when/c:otherwise) and that it uses # instead of the .
It is important to note that I am talking about jsp2 and tomcat 5, not
the jsp1 in
tomcat 4.
A while back I looked in detail at the jsp/velocity comparison on the
velocity site.
There are several issues with the comparison. The person writing the
case study
was cleary biased towards velocity and had never even considered JSTL
(which
in all fairness may not have been available at that time). Looking at
the code
(both the velocity and jstl versions are below) I think that velocity
clearly had
an influence on the jsp2/jstl constructs.
The first thing I noticed was that the two pages do not do the same
thing.
The jsp turns off the session (the vm does not). The jsp stores
variables that
are never used which were factored out in the vm version. The vm version
is missing required code (for example, the repCode and urlEvent
variables
are never defined).
The jsp page is also *very* poorly written using scriptlets. You should
rarely need
to use scriptlets in jsp1/jstl pages, and I suspect with jsp2/jstl, you
will not ever
*need* to.
With struts, you do not need to use jsp:useBean tags either because
the controller
does that for you.
The jsp2/jstl version is a bit more verbose because it is based on xml
so you
cannot have things like if/else/end because they are unbalanced, but
other than
that, there are no significant differences.
After converting the page to use JSTL and eliminating ALL of the % %
stuff, we
get something more like this:
===
The JSP version:
===
table width=600 border=0 cellspacing=0 cellpadding=4
bgcolor=white

RE: Problem with tags and overloaded methods
I reiterate, I believe it's a bad idea to use the same method name for two different property mappings. If you can find some documentation that recommends you do that, I'd like to see it. I believe Tim is referring to what is defined in section 8.3.3 of the JavaBeans spec, Indexed properties, which states: - Thus an indexed property foo might be represented by four accessor methods: public Bah[] getFoo(); public void setFoo(Bah a[]); public Bah getFoo(int a); public void setFoo(int a, Bah b); That's exactly what I'm thinking about. The functions that failed didn't look *exactly* like that though, their signatures looked like this: public ArrayList getFoo(); public void setFoo(ArrayList a); public Bah getFoo(int a); public void setFoo(int a, Bah b); The unindexed getter and setter used an ArrayList instead of an array of the base objects. On the page that worked, the unindexed getters and setters did use an array of base objects. I can only guess that the property inspector in 1.3.1_10 is so extraordinarily picky that it won't accept the ArrayList but will accept an array of base objects. I guess I could use the toArray method of ArrayList. I seem to remember having trouble with that method in the past, though. -- Tim Slattery [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: microsoft sqlserver driver struts
Ian, This is the way I tried first as it seemed most logical to use the SQLServerDataSource type from the mssqlserver.jar but this doesnt work for me. The only one that made some progress was the com.microsoft.jdbcx.base.BaseDataSource but then this threw some strange error which said: java.lang.NoClassDefFoundError: com/merant/jdbcspy/SpyLogger at com.microsoft.jdbcx.base.BaseDataSource.setLogWriter(Unknown Source) I've had a look into this but I don't see why this error should be occuring. Maybe there's something wrong I have done with where I've put the jars.. I have three jars: mssqlserver.jar, msbase.jar and msutil.jar. the last two look to be pretty similiar with regards to what they contain. I was wondering whether this could be causing conflicts or something. As I said, i can connect fine to the datasource from a test class but going via struts is causing this Invalid DataSource problem.

yes it is possible to solve this in a number of ways. I just wanted to
know if the is an easy way of doing it. I've looked at the
struts/validatior implemtentation, it would only mean changing one line

approach ;)

RE: Problem in nested tags- Very Urgent - Please Help
I have not understood your problem completely.
But this looks like more a problem of resetting the list in form than anything else.
Firstly, if you are using request scoped form, then why going from page 1 to page 2
will apend the beans to form?
Are you sure you are using request scoped forms?
If the form is session scoped, make sure you reset the list to empty properly.

hi,
i'm trying to use hubert's (and shirish's) approach on request-scope, and as long as
the amount of rows are fixed it works well.
BUT now i have an additional feature on my page and that gives me headaches.
actionOne gets the rows from the dto-bean and initializes the jsp.
on the jsp-page with the form over the rows, i have an additional form where the user
can toggle through different versions of my db.
this form submits to actionOne where the action is supposed to fetch another set of
rows, according to the parameter given.
let's say: choose february 12th there are 12 rows to display, choose february 15th
there are 15 different rows, choose the next day there are 10 rows.
with this approach, starting with february 12th i get 12 rows. changing to february
15th i get the old 12 rows and the new 15 rows added to, going back to feb 12th i get
the old 27 rows and again the 12 rows from feb.12 added to and so on and on
is there a way to reinitialize the autopopulation method or even to temporarily
disable autopopulation on lists with nested properties?
any adwise or code snippets are warmly welcomed

If that is the case - then maybe thats your problem - if the struts-config.xml says its request, thats where struts will look for it and, if it doesn't exist, it'll set a new one up in request scope (even if you already have one under the same name in session).

Re: microsoft sqlserver driver struts
ok i've manager to connect to the datasource! What I did was to move my jars into common/lib. Now I have another problem though. For some reason this driver does not like my queries - more specifically it does not like table names used on their own but only likes them when the database name and database user is inserted before it like 'dbname.dbo.user_table'. Why is this? I cannot change all my queries (and there are alot of them) so that they have this prefix as it will cause many problems if the application has to be ported to another database. Is this an SQL Server database setting, or something to do with the driver itself? I know I'm getting off the struts issue now but any help would be great! :) - Original Message - From: Claire Wall [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, February 27, 2004 3:19 PM Subject: Re: microsoft sqlserver driver struts Ian, This is the way I tried first as it seemed most logical to use the SQLServerDataSource type from the mssqlserver.jar but this doesnt work for me.

RE: html:link action - how to append query string
You have I think three choices, in preferred order:
1. Use the paramName, paramScope, and paramProperty attributes of
html:link
(see
http://jakarta.apache.org/struts/userGuide/struts-html.html#link)
This may not work with the page scoped variable defined the way you've
done it, I don't know.
2. Use Struts-EL and add ${value} into your link string
3. html:link page='/scopeAction.do?row=% =value %'
I think your core problem is to pass an variable without the param
attributes you need to contstuct and send a URL, not the name of an action?

Re: microsoft sqlserver driver struts
If you're switching JDBC drivers, take a look at JSQLConnect from J-netdirect. We found it performed MUCH better than the driver from Microsoft.

Yes, Velocity has been around for quite awhile now, and it was intended
to address many of the problems inherent in (older versions of) JSP.
Nowdays JSP (especially JSP2) coding techniques and technologies have
rather caught up with velocity. Your assesment that it doesnt add much
value over the EL capabilities in JSP2 is pretty much on the mark. Of

I am starting to develop an application using struts and have been
looking round the rest of the Jakarta project and came across the
Velocity project.
I was interested to see which which people recommended for a relative
newbie
After looking at velocity, I am certainly of the opinion that it adds no
value over jsp2/jstl. It offers absolutely nothing that the jsp2/jstl
combination does not. The only difference is that velocity is a bit more
terse (if/else/end instead of
//) and that it uses # instead of the .
It is important to note that I am talking about jsp2 and tomcat 5, not
the jsp1 in tomcat 4.
A while back I looked in detail at the jsp/velocity comparison on the
velocity site.
There are several issues with the comparison. The person writing the
case study was cleary biased towards velocity and had never even
considered JSTL (which in all fairness may not have been available at
that time). Looking at the code (both the velocity and jstl versions are
below) I think that velocity clearly had an influence on the jsp2/jstl
constructs.
The first thing I noticed was that the two pages do not do the same
thing. The jsp turns off the session (the vm does not). The jsp stores
variables that are never used which were factored out in the vm version.
The vm version
is missing required code (for example, the repCode and urlEvent
variables are never defined).
The jsp page is also *very* poorly written using scriptlets. You should
rarely need to use scriptlets in jsp1/jstl pages, and I suspect with
jsp2/jstl, you will not ever
*need* to.
With struts, you do not need to use tags either because
the controller does that for you.
The jsp2/jstl version is a bit more verbose because it is based on xml
so you cannot have things like if/else/end because they are unbalanced,
but other than that, there are no significant differences.
After converting the page to use JSTL and eliminating ALL of the
stuff, we get something more like this:
===
The JSP version:
===
bgcolor=white
Topic: ${meeting.topic}
var=event
value=${meeting.participation[event.fromId]} /

value=${yapper.participantId} /

MockStrutsTestCase problem
I'm having a problem setting up tests where errors are created during
validation by a DynaActionForm using MockStrutsTestCase. Here's my code:
The DynaActionForm:
===
package test;
import javax.servlet.http.*;
import org.apache.struts.action.*;
public class BogusForm extends org.apache.struts.action.DynaActionForm {
ActionErrors errors = new ActionErrors ();
public ActionErrors validate ( ActionMapping mapping,
HttpServletRequest request ) {
errors.add ( error, new ActionError ( error.message ) );
return errors;
}
}
The Action:
===
package test;
import javax.servlet.http.*;
import org.apache.struts.action.*;
/**
* @struts.action
*name=BogusForm
*input=.doActivity
*path=/Bogus
* @struts.action-forward
*name=doActivity
*path=.doActivity
*/
public class BogusAction extends org.apache.struts.action.Action {
public ActionForward execute ( ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response )
throws Exception {
return mapping.findForward ( doActivity );
}
}
The MockStrutsTestCase:
===
package test;
import javax.servlet.*;
import servletunit.struts.*;
public class TestBogusAction extends MockStrutsTestCase {
public void testFormPassed () {
setRequestPathInfo ( /Bogus );
actionPerform ();
verifyNoActionErrors ();
}
public void testFormFailed () {
setRequestPathInfo ( /Bogus );
actionPerform ();
verifyActionErrors( new String [] { error.message } );
}
}
The result:
===
test:
[junit] Running mori.web.controller.registry.test.TestBogusAction
[junit] Tests run: 2, Failures: 1, Errors: 0, Time elapsed: 2.435 sec

Since the Form just creates an error, I should get exactly the opposite test
results from what I'm getting, right? It seems as though the
MockStrutsTestCase cannot see the errors generated by the DynaActionForm
even though the source says it should do exactly that. Any help appreciated.

You have I think three choices, in preferred order:
1. Use the paramName, paramScope, and paramProperty attributes of
html:link
(see
http://jakarta.apache.org/struts/userGuide/struts-html.html#link)
This may not work with the page scoped variable defined the way you've
done it, I don't know.
2. Use Struts-EL and add ${value} into your link string
3. html:link page='/scopeAction.do?row=% =value %'
I think your core problem is to pass an variable without the param
attributes you need to contstuct and send a URL, not the name of an action?

Re: Problem with tags and overloaded methods
Slattery, Tim - BLS [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I reiterate, I believe it's a bad idea to use the same method name for two different property mappings. If you can find some documentation that recommends you do that, I'd like to see it. I believe Tim is referring to what is defined in section 8.3.3 of the JavaBeans spec, Indexed properties, which states: - Thus an indexed property foo might be represented by four accessor methods: public Bah[] getFoo(); public void setFoo(Bah a[]); public Bah getFoo(int a); public void setFoo(int a, Bah b); That's exactly what I'm thinking about. The functions that failed didn't look *exactly* like that though, their signatures looked like this: public ArrayList getFoo(); public void setFoo(ArrayList a); public Bah getFoo(int a); public void setFoo(int a, Bah b); The unindexed getter and setter used an ArrayList instead of an array of the base objects. On the page that worked, the unindexed getters and setters did use an array of base objects. I can only guess that the property inspector in 1.3.1_10 is so extraordinarily picky that it won't accept the ArrayList but will accept an array of base objects. Well, it's not supposed to work with anything other than an array, so if it ever worked with an ArrayList, then I guess you were lucky - or is that unlucky? ;-) I guess I could use the toArray method of ArrayList. I seem to remember having trouble with that method in the past, though. Shouldn't be a problem - I've used it for exactly this purpose (although I'm using JDK 1.4.2, not 1.3.1). -- Martin Cooper -- Tim Slattery [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [OT] JSP or Velocity
There is one *huge* gripe I have about JSP that many people probably don't care about. But if you do care about it, it can be pretty much of a showstopper, and drive you to use Velocity instead. The problem is that JSP *must* be invoked in a servlet request / response environment. Why is this a problem? Here are a couple of examples: 1) You decide to use JSP to build an application in which customers may want to modify (some of) your pages to develop their own look and feel. JSP is a great choice, because it's standard and well known. Everybody is happy. Now you add HTML mail notifications to your application. Customers may also want to customise these, just as they did the web pages. But since these notifications are not created during processing of a web request, there's no request / response environment in which to invoke a JSP page. You have a couple of choices - use a different templating language for mail notifications, or make a URL request to a separate servlet that's there just to invoke the JSP page. In the latter case, you'll likely want to add security constraints so that external requests for that servlet can't be made. Yuk. 2) You have a reporting web application that displays awesome reports and charts to interactive users. Now you need to add the capability to generate these reports in the background, because they may take a long time to generate, and you want to be pro-active and cache them for the user. Effectively, you're now back in the same scenario as (1), where you either have to jump through hoops to be able to invoke a JSP page outside a request / response, or you need to choose a different templating language. 3) You have an application that is sufficiently dynamic that you need to be able to generate page templates on the fly, and then invoke them. In a JSP environment, you are now going to have to deploy the JDK, rather than just the JRE, in a production environment, which will make a lot of IT people very uncomfortable (if they allow it at all). In addition, you're going to have to solve the interesting problem of where you can write the JSP files to the disk such that the container will actually invoke them for you as JSP pages. This is especially interesting if you need to do it in a portable manner. Don't get me wrong - I think JSP is great, especially in its 2.0 flavour, or with JSTL.

struts-faces doesn't update pages correctly when using tiles
I'm refactoring a Struts+JSTL application to use JSF too, and I have a problem when using the struts-faces library. Everything works ok until I use a ForwardAction to navigate to an action like this: action path=/MainPage type=org.apache.struts.actions.ForwardAction parameter=.mainPage/ .mainPage is a Tiles page defined like this: definition name=.base page=/faces/DefaultLayout.jsp put name=title value=/DefaultTitle.jsp/ put name=headerSpecific value=/Blank.jsp/ put name=content value=/Blank.jsp/ put name=footer value=/DefaultFooter.jsp/ /definition definition name=.mainPage extends=.base put name=headerSpecific value=/MainPageHeaderSpecific.jsp/ put name=content value=/MainPageContent.jsp/ /definition I'm using my own RequestProcessor registered on the config file of struts: controller processorClass=es.udc.fbellas.j2ee.miniportal.http.controller.frontcontroller.MiniPortalRequestProcessor/ The mapping works fine except for I have to load the browser url twice.

I haven't been on many, but this is by far my favorite list, even though I am mainly a spectator. I lashed out because this question clearly didn't belong here.

The little bit of unfriendliness, I dunno why it came out. Unprofessional, it shouldn't have came out. What's happening to the struts mailing list? Of late people have been more than willing to crucify users for any reason. I think its because sometimes(or more recently) people ask/ed questions that clearly don't belong on this list. On top of that, it shows that they have not put in any effort to get the answer, before asking the question here. In this case, I am sure there are tons of people on this mailing list who would love to talk about java gc, but question just wasn't asked right, at the right place.

Plenty of people who don't really track version numbers are using it happily, so the urge to actually cut a release is not too strong. I'm not claiming we're angels, but we're doing a lot better than Maven is. ;-) From Struts 1.0.2 Final to Struts 1.1 Final took 1 year, 4 months. During that time, people still had a Final release to work with. Maven has been in development for almost *3* years, with *no* Final release to work with... That said, there are some intrepid Maven fans who are working on getting the Maven build for Struts to the same point as the Ant build system My enthusiasm for Maven is all about lowering the barrier to entry. I used to share that enthusiasm. It has faded over time, however, as it became apparent to me that, once you get past the easy part, writing preGoal and postGoal scripts isn't much different from writing Ant scripts. Oh, and Maven changing the way it does things didn't help either. ;-) I think long-time Ant/Struts builders forget how tedious it is to set up the build.properties file. And that's just to compile; if you use an IDE you have another headache getting a Struts project set up. That is certainly true. One of the things Maven does for you, to ease the build process, is decide where the dependencies are going to come from. If we did that in the Ant build files, it would make it almost as simple as Mave, but then, because they're Ant build files, people would complain that they were not sufficiently flexible. That makes it hard to win. ;-) (When it comes to IDEs, though, most of them know about Ant, but don't yet know about Maven at all, so there's not so much of a case for Maven there, IMHO.) -- Martin Cooper Anyway, no need to proselytize...

RE: html:text works, bean:write fails [Resolved]
Well the following fixed it:
bean:write name=reportForm property=totalInventory/
The problem was the case in the reportForm. The form bean was named
ReportForm and I did not realize the case was changed when set in the
session.
I used the following snippet of code to help in the debugging (I sure wish I
had tried this earlier) and placed it in my failing jsp page:
%
HttpSession ses = request.getSession();
String test;
if (ses == null) {
test = nosession;
} else {
java.util.Enumeration en = ses.getAttributeNames();
StringBuffer buf = new StringBuffer();
while (en.hasMoreElements()) {
buf.append(en.nextElement());
buf.append(br);
}
test = buf.toString();
}
%
%=
test

I think this is what you'd be looking for:
%@ taglib prefix=c uri=http://java.sun.com/jstl/core; %
c:set var=users value=${pageContext.users} /
c:set var=user value=${users[0]} /
I'm pretty sure that arraylists (being that they are collections) in the c: taglib
will take brackets...

I certainly did a lot more mistakes in this direction when I was younger. Still, Viru had a problem and searched for 'rays of hope' here.

Then you're just at the wrong end of the gun; I know the feelings one has in such a situation. Well, the list may be about Struts in the first place, but most of us are experienced developers who don't do only Struts, but have a much more wide- spread focus, so if we can be of help, we should forget about formal directions and just use our experience to help those facing an infavorable situation to 'save their faces' if we can. Each of us could be in a situation like this one day, too. Alas. Your current post shows you have the courage to recognize mistakes and stand to your deeds. Well, not everybody would have done that. IMHO this clearly deserves respect. Now. A final end to all these sad things and back to work. Well, 'Peopleware' is a famous book about common mistakes in software development, with the first version released in 1989, but things obviously have stayed more or less the same over time. There are many interesting things in this book, and most of them I found to be just correct when compared to my personal experiences over time. IMHO a book everyone who is responsible (in any role) for IT projects should have read once, at least. Basically, it just says your goal should be to form 'jelled' teams and treat them in a human way. Plus, you have to provide the en- vironment for that. The 'Black Team', which existed in reality, is an example of how good developers working to- gether can make a team become something bigger than the sum of its parts. They customarily wore black, hence the term 'Black Team', and were considered 'Gurus' other- wise, but kept humble still, being just proud to be part of this special team. A certain attitude and a diffe- rence in stance. Then, if someone is good, respect will come automa- tically. You don't have to make a fuss about it. That's the difference. Real gurus don't talk or judge, they just do. -- Chris. But as I get the chance here to add something to my recent posts: Well, I was focused on execution times. The same is true, of course, in case of memory consumption. There is no way to 'switch off' GC. But there typically are 'hotspots' in terms of memory consumption, i.e. where a lot of Objects are created. Then, trace your code and check if it retains unneeded strong references which hinder GC from reclaiming their memory space. There are certain pitfalls, in particular when dealing with arrays or Collections, but the overall matter is too complex to lay it out in full here. -- CLIP - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If that is the case - then maybe thats your problem - if the struts-config.xml says its request, thats where struts will look for it and, if it doesn't exist, it'll set a new one up in request scope (even if you already have one under the same name in session).

I'm also not clear whether your finding out your form has been 'wiped' as soon as you get into your action and before you set it up as session scope or after that when you get to your detail screen. Could you clarify that as well please.

RE: [OT] JSP or Velocity
Navjot,
Though I haven't tried Velocity, I like the idea that my stub-pages can be
easily edited in HTML editors. How do your manage letting your designers
alter the JSP layouts? Do you have them use some (and if so, what is it)
HTML editor which is (Stuts JSP EL) aware?
Regards,
David

Basically, i use velocity only for email templates and sometimes to generate
other kind of templates from one template where the use of XSLT is not
appropriate.
For web templates, that have more complex requirements, i prefer to use
taglibs. besides el makes life as easy as we may talk in velocity. In
velocity, to comprehend taglibs, you may have have to write lots of
velocimacro.
you may ask for another opinion on velocity-user list as well.

I am starting to develop an application using struts and have been
looking round the rest of the Jakarta project and came across the
Velocity project.
I was interested to see which which people recommended for a relative
newbie
After looking at velocity, I am certainly of the opinion that it adds no
value over
jsp2/jstl. It offers absolutely nothing that the jsp2/jstl combination
does not.
The only difference is that velocity is a bit more terse (if/else/end
instead of
c:choose/c:when/c:otherwise) and that it uses # instead of the .
It is important to note that I am talking about jsp2 and tomcat 5, not
the jsp1 in
tomcat 4.
A while back I looked in detail at the jsp/velocity comparison on the
velocity site.
There are several issues with the comparison. The person writing the
case study
was cleary biased towards velocity and had never even considered JSTL
(which
in all fairness may not have been available at that time). Looking at
the code
(both the velocity and jstl versions are below) I think that velocity
clearly had
an influence on the jsp2/jstl constructs.
The first thing I noticed was that the two pages do not do the same
thing.
The jsp turns off the session (the vm does not). The jsp stores
variables that
are never used which were factored out in the vm version. The vm version
is missing required code (for example, the repCode and urlEvent
variables
are never defined).
The jsp page is also *very* poorly written using scriptlets. You should
rarely need
to use scriptlets in jsp1/jstl pages, and I suspect with jsp2/jstl, you
will not ever
*need* to.
With struts, you do not need to use jsp:useBean tags either because
the controller
does that for you.
The jsp2/jstl version is a bit more verbose because it is based on xml
so you
cannot have things like if/else/end because they are unbalanced, but
other than
that, there are no significant differences.
After converting the page to use JSTL and eliminating ALL of the % %
stuff, we
get something more like this:

RE: Action class calling other Action class
You could do this by just forwarding to an action mapping entry for ActionClassB. In you action mapping for ActionClassA, have multiple forwards. And the logic in ActionClassA would forward to whichever, with 1 of them being ActionClassB. action path=/actionA type=ActionClassA name=form scope=request forward name=SUCCESS path=/do/actionB / forward name=FAILURE path=/test.jsp / forward name=CANCEL path=whatever / /action action path=actionB type=ActionClassB name=form scope=request set-property property=secure value=true / forward name=SUCCESS path=/any.jsp / forward name=FAILURE path=/anyOther.jsp / /action hth -jayash -Original Message- From: Ramadoss Chinnakuzhandai [mailto:[EMAIL PROTECTED] Sent: Friday, February 27, 2004 12:29 PM To: [EMAIL PROTECTED] Subject: Action class calling other Action class Hi, I hv ActionClassA ==Display JSP of ActionClassA having a link to Edit JSP of ActionClassB==ActionClassB=Edit JSP of ActionClassB==ActionClassB(Update records)=dispatch control over to ActionClassA.
