referring to the DTDs
I was wondering if there is a way for an xml doc to look for a dtd in 2 or 3 places. Can you do this: !DOCTYPE struts-configSYSTEM "file:///c:/bea/wlserver6.0/config/Wcom/applications/mydomain/WEB-INF/struts-config_1_0.dtd "file:///c:/dtds/struts-config_1_0.dtd "struts-config_1_0.dtd The reason is that I want to refer to the dtdusing a RELATIVE path on both UNIX and NT

Indexed properties
Hi, What I want to do is to have multiple text fields in a table get assigned to an array or collection property in an ActionForm. I've followed a few threads in the newsgroups about this and have tried some jsp code: logic:iterate id=myObject name=indexedForm property=indexedPropsList TR TDhtml:text name=myObject property=name indexed=true//TD /TR /logic:iterate but this produces this jsp error: /pages/test/TestIndexedPropertyPage_Body.jsp(11): for tag 'text' handler type 'org.apache.struts.taglib.html.TextTag' has no property 'indexed' Is the indexed property a non-standard struts patch / extension I have to use?

adding a new method to the bean which duplicates the code

I then display the string with:

You can try this:
bean:message key = '%= term.type + bean.getType() %' /
or, better (does not work with struts 1.0 but with CVS 1.1)

Subject: RE: what setters do i implement in an indexed tag ?
Hi,
You need 3 methods, a getter and a setter for the Vector (or other
arraytype object) and a getter for single object in your arraytype
object, i.e., getObject(int inx){ return myVector.elementAt(inx) }
Just like on the webpage mentioned.
the setters needed should be defined on the object your are returning
in the getObject method. That is, what happens when the form fild data
is passed to the form object is:
getObject(inx).setProperty(someProperty).

In the indexed tags write up at
http://www.husted.com/about/struts/indexed-tags.htm, it only mentions the
two types of get methods required in the action form. It doesn't mention the
setters that are required. It looks like the getParameterList() method is
only used by the iterate tag. To populate the form on submit the only setter
needed is:
public void setParameter(int index, Parameter p){...};
In your case that means:
public void setParameter(int index, FieldMapping f) {...};
You probably don't need:
public void setFieldMappings(java.util.Vector newFieldMappings) {
fieldMappings = newFieldMappings;
}
unless you use it in your action to populate the form object before
displaying the form jsp.
I am about to try this myself so this is just a guess.

I've created a page using indexed tags (neat stuff!).
Here is what is currently working for me:
o If i populate the form's vector, values from that vector are displayed in
the jsp
Here is what it not working:
o when the form is posted back, the vector is null (in the struts perform()
method)
I suspect i haven't implemented some sort of setter within the form but i
can't find an example as to what method should be implemented. I've tried
ArrayList and using parameterList instead with no different result.

I have list of lets say users. Each user has a link that maps to edituser action. That action then gets executed and it places userbean to request scope. Then struts forwards action to edituser.jsp. Edituser.jsp has form that has action mapping set to updateuser. When user submits that form which binds to userform action form the validate method of that actionform gets executed. If validation errors occurred then we get back to input form (which is edituser.jsp or edituser.do -- which to use?). And this is the point when I do not really understand what I should do, because when user gets back to edituser.jsp or edituser.do then there is not anymore that userbean is request scope. And because edituser.do does not have any forms associated with it then I should instead use edituser.jsp as input for updateuser action. But how I then write that form (jsp-page)? I have several options: 1. put userbean in session scope (might be problem in multiserver environment also the modifications that user entered are not visible). 2. Have another jsp-page that does not populate the form from userbean. Not good option because almost the same form needs to be written second time. 3. Use logic tags to check the existence of userbean and if it does not exist then do not populate and let the form populate itself from posted form. Same problems as in 2. 4. Somehow prepopulate the form with no manual population, but automatically. So do I pre-populate the form. What code I need to put in edituser action that previously placed userbean in request scope.

Re: Workflow impasse? and more
Hi All, Well I've finally got around to moving my struts subscriptions to a different address so I can setup rules etc to manage the number of mails on the lists! Moving them away from my work mail address is a good thing... So why am I telling you all this? Well I , like Craig T, signed up for several areas on the 1.1 Todo list a while back and like Craig have been busy with work and being away on holiday and training. So keeping up with the volume of mail has been difficult let alone contributing anything constructive. So I, like Craig, am going to have to cut down what I am involved in to make it fair to others and be able to contribute properly without spreading myself too thin. So I am going to back out of the following areas for the following reasons: Standard Validations Client Side Validations - because I have not done the work I expected to in this area and therefore feel I probably shouldn't buttin on these! EJB Design Patterns - for similar reasons. Although I have been working with EJBs I think there are others who are better qualified to lead this piece. I will of course contribute where possible to these areas but feel I am unable to lead them or take a direct role in designing/writing these. Which leaves the following: Multi-page form support - I think this really may tie in with the Workflow processing Workflow processing - I am working on workflow at the moment from a 'backend' perspective i.e. at the EJB layer which I hope will help cement my ideas for the Struts workflow. More on this later. Role-based Action Execution - I have been looking at JAAS and security in general and need to look into the specs a bit more to understand what _must_ be supported by containers and what _tends_ to be supported before we make a decision on exactly where to go withthis. Again more later. I hope this will enable to contribute more than I have in the past and get things moving. Apologies for anyone expecting me to take the others areas through to completion. So on to Workflow. As Ted suggests I also believe the fundamentals are there in the framework already. There have been several discussions about exactly what the workflow piece is but I think Ted's implications are the best. I don't think we are trying to design something that is a GUI nor are we trying to make something that conforms to standards which are in their infancy. This is not to say that support for products ( I think Visio for instance was suggested) should not come later but I think this is in addition to the underlying functionality which is to link Actions together to form a business process with pre- and post-requirements. This is where the thought on the multi-page forms comes in. I have been thinking about this a lot lately and have a few ways of doing this which when I cement them a little more will post here. I think we need to get down a solid set of requirements ( I think Ted's are a good start) and be clear what we are trying to achieve (I have tried to outline my view above) before we can proceed and I will take a proper look at the code examples Ted outlines in his mail. Much of the discussion so far has been on several tracks all under the global term 'workflow'. (Please don't take any of this as criticism - I am aware I haven't contributed much up until now - just observations and an attempt to get this going). So any comments on what we are trying to achieve and how? (and I am waiting for the slap too... ;) And then the security thing I have been primarily working with BEA Weblogic and working on a banking system so security has been key. We have had various discussions with BEA and finally got some answers so I have a clear idea of how BEA do things and how we may be able to fit this in to struts. What is currently not clear and Craig M has alluded to before is that the specs aren't really explicit in this area and each application server tends to do things in its own way. So I intend to look at the specs a little more to see what they should at least all support and then work on whether we want to link something into that or produce a struts specific implementation ( which obviously should abstract things so that people can plug in their app server specific stuff if necessary, although Struts is unlikely, at least at this stage, to support this 'out-of-the-box'.) As the saying goes...I'll be back... I hope I haven't stepped on anyone's toes here and I hope I can contribute properly in the future which I haven't been able to up until now due to other commitments. Could I ask someone who has commiter privs to remove me from the areas above on the todo list? Many thanks, Kind regards and keep up the good work! Nic Ted Husted
AW: Struts + JBoss
Hi.
i've had trouble with jboss 2.2.2/tomcat 3.2.2...for this reason i dropped
back to the 2.2.1/3.2.1 version and everything worked fine...
Ok, I dropped back, too, now - but without success. Are you using Struts 1.0
or a newer version?
in my experimentation, it seems to be a classloader issue...any classes
you
want to access from another class must be either on the same level, or
higher in your classpath...if a .jar file that is located in the
jboss/lib/ext directory is accessing a struts class or action class that
is
in your WEB-INF/lib/this.jar file, then it will give you this message...
That's the way I am using the struts.jar now (in jboss/lib/ext). Does it
work at you, when you use 2.2.1/3.2.1 ? Or do you have any suggestions where
to put it otherwise... (I tried ear/war/WEB-INF/lib and the root of the .ear
as Gregor suggested and many other locations - without any success).
it's been a real pain :-)

Subject: Struts + JBoss
Hi.
Has anyone of you managed to make Struts and JBoss working together?
This is my current situation: I use JBoss-2.2.2 + Tomcat-3.2.2 (by
run_with_tomcat.bat - so they are running in one VM) and Struts 1.0.
The problem is briefly: When I deploy a .ear-archive that contains a
.war-archive with the classes Struts should use (e.g. the form and
action-classes), it throws an exception:
javax.servlet.jsp.JspException: Exception creating bean of class
path/DetailsForm: java.lang.ClassNotFoundException: path/DetailsForm
at
org.apache.struts.taglib.html.FormTag.doStartTag(FormTag.java:568)
These are the lines of the Struts source-code where the exception is
thrown:
try {
Class clazz = Class.forName(type);
bean = clazz.newInstance();
if (bean instanceof ActionForm)
((ActionForm) bean).setServlet(servlet);
} catch (Exception e) {
throw new JspException
(messages.getMessage(formTag.create, type,
e.toString()));
}
The reason I blame Struts for that is the following:
When I try to instanciate DetailsForm manually from the .jsp-page there is
absolutely no problem. But Struts seems to use another classpath.
Using the same .jsp-pages/classes/struts-config.xml/web.xml with Tomcat
and
J2EE-reference implementation works fine. - So I can say for sure that
struts-config.xml and web.xml okay.
This is the way the .ear-File looks like:
.ear
META-INF\
sun-j2ee-ri.xml, Manifest.mf, application.xml
war-ic.war
lots of stuff
WEB-INF\
web.xml, struts-*.tld, struts-config.xml, global.properties
classes\
Resources.properties
all my classes
ejb-jar-ic.jar
the beans (they work fine)
I once tried to add the .class-files manually to the classpath (not the
ones
that are created by jboss, when I deploy the .ear, but the .class-files,
that I built before building the .ear-file).
After that Struts was able to find the classes, but my classpath was
completely messed up. The global.properties for example (which is
accessible
via InputStream is = getClass().getResourceAsStream(/global.properties)
normally) was not found any more.
Thanks in advance

It also could have bean:message functionality. I know that this isn't a big issue, but sometimes you want to display something in form that is not editable (e.g. Primary Key). I know that I can use html:text readonly=true for most cases, but html:label tag could give you more flexibility.

It just prints string values like bean:write tag but does not require name attribute and cannot be used and associated with form. Of course I meant: It just prints string values like bean:write tag but does not require name attribute and can be used and associated with form.
Feature enhancement - triggering an Action
This thread appeared on the list earlier this week. QUESTION - JonathanCan someone tell me if there is a way to configure an action to match a pathregardless of how deep it is in a directory?ANSWER - TedNo. There is not a way to do this, without changing the way Struts isprogrammed to behave. You could request a feature change in Bugzilla, andbring it up on the DEV list for discussion.==As I was experimenting with our struts app I ran into the situation where Iwanted a generic "path-indifferent" name to trigger an action. Forinstance, in the following three cases:"/charts/display.do""/news/display.do"/events/outdoors/display.do"I didnt care about anything except the existence of "display.do" ANYWHEREat the end of ANY path. In fact, isnt this exactly how the servlet istriggered with ".do" This is what I expected, and the current Struts designwont let me do this. Do you all think this is an important feature? Ireally would like it as it can give a sense that the behaviour is common,and saves me time in thinking about how to properly trigger that particularaction I was wanting.

DataSource and Factories
Hi again, I would like to seperate my buisness logic from the data layer. Say I have an object Person, that has the fields id, firstName and lastName. The only constructor I provide is one which takes two arguments (id, firstName and lastName). The person objects will be stored in a certain Database, but this may change in the future, this is why I use a factory. The factory takes an id, connects to the DB, retrieves the data, creates the Person object and returns it. This pattern also comes in handy, when you have classes that inherit from Person. If the DB access would happen in the constructor, one could only create Person objects, with a factory, you can create an object of the real type instead. Anyway, what I want is to get a DataSource without knowing about a servlet. Is this somehow possible? Is there some static access to the DataSource Repository? Tia, Andreas

Re: Missing type on declaration - any poniters- perform Q
I have tried numerous variations public ActionForward perform (
public class ActionForward perfrom (
Please explain a bit more as my code is more or less the same as in the
Building Controller Components - Action Classes.R ef Struts User Guide -
Note i thought that the method perform will as it say's on the tin
perform ActionMapping and ActionForm etc thus why they are not
functionally.Thus what point am i missing.

newbie: initial values
Hi.
I apologize for this probably really stupid question, but I was not able to
find a suitable answer anywhere, yet...
In my user management I want to provide a way that the users can change
their address (they are already stored in a database). Thus I need a form
with the old address as initial values.
In other words: There is a session variable UserId. How can the form bean
that is used by edituser.jsp access this userid to adjust it's initial
values.
I can write name = peter; in the constructor of my EditUserForm class.
But I want that the name is taken from a database depending on the UserId of
the session.
public void reset(ActionMapping mapping,
javax.servlet.http.HttpServletRequest request) seems not to be executed.
Is something like that the right way:
public class EditUserForm extends ActionForm {
protected boolean initialized = false;
protected String name;
String getName() {
if ( !initialized ) doInitialize();
return name;
}
public void setName(String name) {
this.name = name;
}
public void doInitialize() {
name = get Name from Database... (but how can I access the
sessionvariables here?)
initialized = true;
}
}
Is there a new instance of EditUserForm created each time a user accesses
the page?

Multiple checkboxes, same name...
Hi all. Very new to this list and struts, but using it pretty successfully for a project at work. Good looking framework. Now the question: I have a form that will list anywhere from 0-9 vehicles. I have to allow multiple selection of vehicles. Currently I'm using html:select multiple=true... type tags, but would like to use checkboxes, so would the following work? Create a bean with name/value pairs for each vehicle and do a logic:iterate... tag and generate an html:multibox... for each entry (the selected vehicles are an array in a form bean). The above sounds pretty reasonable, but I'm unsure how to get it to work. Specifically, how to get the proper value= attribute in the multibox tag: !-- vehicles is a page-scope hashtable -- logic:iterate id=entry name=vehicles ** how to get the key property of 'entry' into value attrib? ** html:multibox property=principalOperators value=??? bean:write name=entry property=value/ /html:multibox /logic:iterate Thanks in advance, Carmine Lucarelli

Implement an Action which fills the form with values. What I usually (I use struts one month :-) do in such edit something situations: I create I an EditTgingActionForm with properties a) the key properties b) the dependent properties c) optional - a boolean indicator isEditing I create an EditThingAction which: d) checks to see, whether the form has been filled from HTTP (which means: b) properties are filled and c) is true) if so, then it performs the updates. If not, no updates. e) fills the properties b) from the database using the key properties a). In my JSP which leads to that action, i use parametrized link: a href=editthing.do?id=BLA (generated with html:link) As you see, properties b) or c) are not supplied, so the Action knows, there is nothing to be updated, it just retrieves the data. editthing.do then forward to a JSP, which displays the retrieved data and when submitted (again to editthing.do) EditThingAction know, it has to update the data. -- gR
Re: Refresh button and Back button
The back button problem is standard. You need to use a token to prevent sensitive form resubmission. This is documented in Geary's Advanced JSP book and Core J2EEE patterns. They are both put out by Sun. In short, tokens allow you to determine whether the page should be processed in the normal way. You include a token in the request and save a copy in the session. When the page is submitted, you check that they match. If so, you can do normal processing. If not, you need to decide what to do. Struts supports tokens, but the implementation is opaque (IMHO). Geary's book provides a good treatment. However, there is an error in the code he uses to check tokens (don't have book in front right now, so can't spell it out). I think he does not check all the cases he says he does. At any rate, the code is in the book for the test tokens tag he develops. Even if you used the Struts implementation, you would have to use his logic.

Now the question: [snip] The above sounds pretty reasonable, but I'm unsure how to get it to work.

In this case struts will use the body of the html:multibox tag as the value. So: logic:iterate id=entry name=vehicles html:multibox property=principalOperators bean:write name=entry property=value/ /html:multibox /logic:iterate does what you want.

RE: Struts on IBM WAS 4.0 - Error removing attributes from reques t sc ope!
Pardon my skepticism, but from all appearances, the WAS 4.0 GA release is
out (nothing on the IBM WebSphere site says that the 4.0 you can now
download is beta), and this particular issue is *not* resolved. The
antiquated version of Jasper is still included. And from the response to my
question about this on this list a month ago or so, just dropping in a new
Jasper is not something that's likely to happen quickly. If this issue was
just brought to their attention a couple of weeks ago (meaning that they
didn't know about it), I wouldn't hold my breath on a quick resolution.
I'd love to see the fix appear in a fixpack (and soon) but we tried out 4.0
as soon as it was released the end of June, primarily to see if this issue
was resolved, and were disappointed.

Subject: Struts on IBM WAS 4.0 - Error removing attributes from request
sc ope!
Hello, thanks for you're attention.
I am deploying the struts-example app on IBM Websphere App Server 4.0
and
receive an IllegalArgumentException - Can't remove attribute from
request
scope.
the situation:
I have drilled into the problem and discovered that IBM is using a
significantly different implementation of the class,
org.apache.jasper.runtime.PageContextImpl. Their class alters the logic
of
removing attributes using the methods removeAttribute(String s, int i)
and
removeAttribute(String s).
I have included the code in the next section of the e-mail. In summary,
using WAS 4.0, attributes are not removed from request scope.
This conflicts most directly with the struts framework class,
org.apache.struts.taglib.html.FormTag. FormTag calls
pageContext.removeAttribute(Constants.BEAN_KEY,
PageContext.REQUEST_SCOPE)
and pageContext.removeAttribute(Constants.FORM_KEY,
PageContext.REQUEST_SCOPE) within the doEndTag() method.
Either of these method calls will generate an IllegalArgumentException
on
WAS 4.0.
the code (more or less):
org.apache.jasper.runtime.PageContextImpl (note: not the same code as
used
in tomcat's implementation...)
public void removeAttribute(String s, int i)
{
switch (i)
{
case PAGE_SCOPE:
pageScopeAttributes.remove(s);
break;
case REQUEST_SCOPE:
throw new IllegalArgumentException(Can't remove Attributes
from
request scope);
case SESSION_SCOPE:
if (session == null)
throw new IllegalArgumentException(Can't access
SESSION_SCOPE without an HttpSession);
theSession.removeAttribute(s);
break;
case APPLICATION_SCOPE:
theContext.removeAttribute(s);
break;
}
}
// and ...
public void removeAttribute(String s)
{
pageScopeAttributes.remove(s);
}
// (pageScopeAttributes is a Hashtable of objects stored at Page
scope
only!)
a partial solution:
Replacing the removeAttribute(String s, int i) method calls with
removeAttribute(String s) within the struts class, FormTag.doEndTag()
relieves the exception, but on WAS 4.0, it will not remove the
attribute!
(in fact, only attributes found in page scope will be removed when the
method, removeAttribute(String s) is called.)
testing results:

Problem initializing (pre-selected) html:select multiple=true

I have a problem with multiple html:select struts tag initialization.
I am unable to initialize the select tag with the values i retrieve
from my database.
I have a JSP with
- a html:select multiple who will retrieve the selected compagnies I
choose.
- a html:options containing all the compagnies in my database
I have in the Form associated with this JSP :
- an attribut rattacheInitialChoisi who retrieve a String[] of compagnies
already choosen
- an attribut listeSociete who retrieve a ArrayList of all compagnies
- an attribut rattacheSocieteChoisie who will retreive a String[] of the
new chosen compagnies
All these attributs are correctly initialized (I saw this in my logs files)
But I am unable to initialize the selected elements of my html:select list
in the jsp thanks to the rattacheInitialChoisi attribut (pre-selected the
select list when the jsp appears)
Has anyone experimented this and have an idea of how to do so ???

application scope problem
Please Help!
In my Struts-Application I create at a certain point (init Method of
myClass extends ActionServlet) a Bean for the Servlet Context.
ServletContext context = getServletContext();
Info info = (Info)context.getAttribute(host);
if (info == null)
{
info = new Info();
info.setBase(test);
context.setAttribute(host, info);
}
Later in a JSP page I have that:
jsp:useBean id=info scope=application class=myPackages.Info/
pContext Bean: bean:write name=info scope=application
property=base//p
But I don't reach the value of the property because every time when I
forward to that JSP-Page the Bean (Info) is created again and it's
properties initialized with null.
Any idea?
What is wrong???

RE: Struts on IBM WAS 4.0 - Error removing attributes from reques t sc ope!
Hi John (or others using struts on IBM WAS),
I was wondering if you have come accross any other negative implications
besides the nasty show stopping Exception from using struts on WAS.
(work-around provided earlier in thread)
In particular I am concerned that struts makes calls to PageContext -
removeAttribute(String s), while in the Jasper code used by IBM, this will
remove page scope attributes only. Primarily, I am concerned with the
struts class, taglib.logic.IterateTag, which appears to be written to
iterate through attributes at any scope.
Any heads-up about struts on IBM is much appreciated.
Thanks a lot,
Mark

Pardon my skepticism, but from all appearances, the WAS 4.0 GA release is
out (nothing on the IBM WebSphere site says that the 4.0 you can now
download is beta), and this particular issue is *not* resolved. The
antiquated version of Jasper is still included. And from the response to my
question about this on this list a month ago or so, just dropping in a new
Jasper is not something that's likely to happen quickly. If this issue was
just brought to their attention a couple of weeks ago (meaning that they
didn't know about it), I wouldn't hold my breath on a quick resolution.
I'd love to see the fix appear in a fixpack (and soon) but we tried out 4.0
as soon as it was released the end of June, primarily to see if this issue
was resolved, and were disappointed.

Subject: Struts on IBM WAS 4.0 - Error removing attributes from request
sc ope!
Hello, thanks for you're attention.
I am deploying the struts-example app on IBM Websphere App Server 4.0
and
receive an IllegalArgumentException - Can't remove attribute from
request
scope.
the situation:
I have drilled into the problem and discovered that IBM is using a
significantly different implementation of the class,
org.apache.jasper.runtime.PageContextImpl. Their class alters the logic
of
removing attributes using the methods removeAttribute(String s, int i)
and
removeAttribute(String s).
I have included the code in the next section of the e-mail. In summary,
using WAS 4.0, attributes are not removed from request scope.
This conflicts most directly with the struts framework class,
org.apache.struts.taglib.html.FormTag. FormTag calls
pageContext.removeAttribute(Constants.BEAN_KEY,
PageContext.REQUEST_SCOPE)
and pageContext.removeAttribute(Constants.FORM_KEY,
PageContext.REQUEST_SCOPE) within the doEndTag() method.
Either of these method calls will generate an IllegalArgumentException
on
WAS 4.0.
the code (more or less):
org.apache.jasper.runtime.PageContextImpl (note: not the same code as
used
in tomcat's implementation...)
public void removeAttribute(String s, int i)
{
switch (i)
{
case PAGE_SCOPE:
pageScopeAttributes.remove(s);
break;
case REQUEST_SCOPE:
throw new IllegalArgumentException(Can't remove Attributes
from
request scope);
case SESSION_SCOPE:

Re: DataSource and Factories
This looks interesting, but I am not sure how I would use it. Would the strategy be to set up an action to run when the application is loaded? Would the action then obtain a reference to the data source and stow it in some repository using JNDI for use by the persistenc layer? That is the solution we think will work. Is this different from that? Thanks, Bud DataSource can be obtained either Deployment descriptor as java:comp/jdbc/MyDataSource (associate a Jndi name to the Datasource )
RE: application scope problem
Hopefully someone will be able to elaborate on this, but I don't believe you
can't use
jsp:useBean id=info scope=application class=myPackages.Info/
interchangablby with struts bean tags.
You should be able to use:
bean:define id=info scope=application name=host /
then, to display:
bean:write name=info property=base/
Also, make sure that you are putting the bean host into the application
scope in you java code.

Re: application scope problem
I'm not sure exactly how the jsp:useBean looks for the
class you specify, but since you are initializing the
class from the ActionServlet it would be safe to
assume it is there so you don't really need the
jsp:useBean. So you should be able to do just this.
pContext Bean: bean:write name=host
scope=application property=base//p
If you weren't sure if the bean existed, you could
check for it with the logic:present tag.

a partial solution:
Replacing the removeAttribute(String s, int i) method calls with
removeAttribute(String s) within the struts class, FormTag.doEndTag()
relieves the exception, but on WAS 4.0, it will not remove the
attribute!
(in fact, only attributes found in page scope will be removed when the
method, removeAttribute(String s) is called.)
testing results:
Even though the attributes weren't removed from the request scope, those
attributes were replaced by new objects the next time. This didn't seem
to
affect the observable behavior of the struts example application.

We really, really want to use struts on WAS 4.0. There seems to be some
logic within struts that relates to null attributes.

Subject: Struts on IBM WAS 4.0 - Error removing attributes from request
sc ope!
Hello, thanks for you're attention.
I am deploying the struts-example app on IBM Websphere App Server 4.0
and
receive an IllegalArgumentException - Can't remove attribute from
request
scope.
the situation:
I have drilled into the problem and discovered that IBM is using a
significantly different implementation of the class,
org.apache.jasper.runtime.PageContextImpl. Their class alters the logic
of
removing attributes using the methods removeAttribute(String s, int i)
and
removeAttribute(String s).
I have included the code in the next section of the e-mail. In summary,
using WAS 4.0, attributes are not removed from request scope.
This conflicts most directly with the struts framework class,
org.apache.struts.taglib.html.FormTag. FormTag calls
pageContext.removeAttribute(Constants.BEAN_KEY,
PageContext.REQUEST_SCOPE)
and pageContext.removeAttribute(Constants.FORM_KEY,
PageContext.REQUEST_SCOPE) within the doEndTag() method.
Either of these method calls will generate an IllegalArgumentException
on
WAS 4.0.
the code (more or less):
org.apache.jasper.runtime.PageContextImpl (note: not the same code as
used
in tomcat's implementation...)
public void removeAttribute(String s, int i)
{
switch (i)
{
case PAGE_SCOPE:
pageScopeAttributes.remove(s);
break;
case REQUEST_SCOPE:
throw new IllegalArgumentException(Can't remove Attributes
from
request scope);
case SESSION_SCOPE:
if (session == null)
throw new IllegalArgumentException(Can't access
SESSION_SCOPE without an HttpSession);
theSession.removeAttribute(s);
break;
case APPLICATION_SCOPE:
theContext.removeAttribute(s);
break;
}
}
// and ...
public void removeAttribute(String s)
{
pageScopeAttributes.remove(s);
}
// (pageScopeAttributes is a Hashtable of objects stored at Page
scope
only!)
a partial solution:
Replacing the removeAttribute(String s, int i) method calls with
removeAttribute(String s) within the struts class, FormTag.doEndTag()
relieves the exception, but on WAS 4.0, it will not remove the
attribute!
(in fact, only attributes found in page scope will be removed when the
method, removeAttribute(String s) is called.)
testing results:
Even though the attributes weren't removed from the request scope, those
attributes were replaced
Changes to values in Form get lost on forward
Hi, I'm sure, this question has arised before, but I's quite hard to find it in the archive. However, this question is rather short, so I hope someone can have a short answer to it. My problem comes up, when I do the following: 1)in YYYAction.perform I set a field of the form to a new value,like System.out.println(importantString before= + myForm.getImportantString()); myForm.setImportantString(The new value); System.out.println(importantString after= + myForm.getImportantString()); 2)then I forward to ZZZAction, (this action uses the same form in the action mapping) 3)ZZZAction.perform: -retrieves some values from the database and populates the form -then forwards to the JSP, that displays the form data In step 1), I see an output like: importantString before=A cup of tea importantString after=The new value But when I look at my JSP, I still see A cup of tea as the value! Could anybody please tell me, what I'm doing wrong? Thanks, Holger
Struts Scalability in a Large Production Environment
All, I have been doing a lot of research into Struts recently. My question is about performance and scalability. First the definitions: Performance = good response time to users Scalability = good response time to a large number of simultaneous users. Usually this is a logarithmic curve that reaches a point where the server has difficulty sustaining the load. Struts will only be used for presentation logic. My Action classes in this framework will access separate business objects that will then access a BEA application server to perform the necessary business logic (EJB's) and return the results. This will be a large production environment with a large number of simultaneous users if we decide to implement this way. The Web servers will be load balanced. Even so, I don't want to implement a framework which requires me to throw a bunch of hardware at it after all is said and done. Does someone have some practical experience of the performance and scalability of the Struts framework with an overhead of 100 simultaneous users? What about 1000? Is there any kind of advice that anyone can offer me before I head down this path in relation to scalability? Thanks, Brian

RE: Struts on IBM WAS 4.0 - Error removing attributes from reques t sc ope!
Yes, WAS 4.0 is a big step forward in usability. However, if you look closely at the struts.jar file that is ships with, it's Struts 0.5. That notwithstanding, the console looks like a pretty sophisticated app. Probably not trivial for them to move it to Struts 1.0.

I had no problems with our test run with WAS 4.0 using the modified struts.jar I posted - heck the console is built with Struts. :-P Frankly, I feel like WAS 4.0 is a dream-come true as far as usability and administration. Yeah, Java isn't up to spec, but what else is new. At least it is easier to maintain.

Re: Problem initializing (pre-selected) html:select multiple=true
Hi. If you want Struts to display values pre-selected, you should leave off
the value= on the select tag altogether.
I haven't tried it with multiple=true, but use html:select
property=category to display the value I previously assigned in my form
under category. Would assume it would work with multiple=true too...

You can get them at http://husted.com/about/struts/indexed-tags.htm, and I attached some example source code to a previous message which was just mentioned, if you want to look at that. Cheers, Dave I have a couple of questions about your mods. At our site we are using a different set of modifications, posted by some other Struts user which seems to accomplish the same thing as your mods. The major difference seems to be that yours requires an additional attribute to specify that the particular input field is to use an indexed property accessor. I'm curious as to why you made this choice? The mods we are using automatically use an indexed accessor if the input field is contained inside of an iterate tag. Do you have an example of when you would have an input field inside of an iterate tag when you wouldn't want to use an indexed property name? (I'm not trying to argue with your decision, just trying to get a better understanding of your thoughts). The other issue, which we just came across today, with the other indexed property mod, is that it would fail to work correctly if you had iterators inside of iterators. We had a case where we used an iterator to access a collection of beans, and then iterated over the contents of each of the beans. The resultant HTML needed to look like this to work correctly: input type=text name=firstTable[n].secondTable[m].propertyName Will your mods handle nested iterators correctly? Finally, are your mods going to be part of the official build, or are they included in some sort of user supplied extensions? I missed the original discussion about your modifications. Thanks!

}
In the original mods that we had, the getProperty method of IterateTag
simply returned the property field value. I modified it to invoke a
propertyName() method whose implementation is the same as that given
above. This allows for a recursive buildup of indexed property fields when
an HTML tag is included inside of any number of nested iterate tags.

Re: calling actionmapping from a URL
The ActionMapping has a property for validation. To call the Action without validation, set validate=false in your ActionMapping. An Action is not a servlet, and you cannot call it directly from an URL. In every case, the request is passed to the ActionServlet by the container. The ActionServlet determines which Action to use by referring to the ActionMappings. So in the example case, you must have mapping named myaction, or else it could not be called. You may wish to set validate=false for that mapping, and leave it at true for the others. If there is some other type of validation occuring in your Action, which you put in yourself, you could check the mapping object passed to perform() to see if validation should be used or not. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 737-3463. -- http://www.husted.com/about/struts/ Jan Fredrik Øveraasen wrote: Hi I have a action class that is used in several actionmappings and in some situations it is called directly from a url, like href=myaction.do, but in these cases the validation implemented prevents me from continuing the process.

Re: Empty Page returned after Action executed
Hello, I have had this problem when I reference a forward that doesn't exist in my config file. You mention that your action returns a reference to continue: (mapping.findForward(continue)) But your line in your struts-config is: forward name=success path=/shipsum.jsp/ rename your forward to continue or return a reference to success like this: (mapping.findForward(success)) Bill Randall Dietz wrote: I'm new to Struts (V1.0) and I'm stuck on what I think is a simple example. I have an Action and an ActionForm bean that do pretty much nothing. Action simply returns a reference to continue (mapping.findForward(continue)) and the ActionForm bean has one attribute, title. What's happening is that when I execute the action (using html:link page=/shipsum.do), the JSP associated with the action is not being displayed. There are no errors, just an empty HTML page with an empty body. Here are the form-bean and action entries I use in my config file: form-bean name=summaryForm type=com.mim.pilot2.SummaryForm/ action path=/shipsum type=com.mim.pilot2.SummaryAction name=summaryForm scope=request input=/shipsum.jsp / Note that by using System.out I have verified that my SummaryAction class is being executed.

Re: Encodings on form submits?
I know this is an old post, but better late than never... :-)
We are doing the following:
1) Specify the content type for the JSP output:
%@ page contentType=text/html; charset=utf-8 %
You can also do this by setting the content type header manually, using
response.setContentType().
2) Specify the content type to the browser:
meta http-equiv=content-type content=text/html; charset=utf-8
3) Specify the default content type to the container. In our case, we are
using Resin, and so do this:
web-app id='/' character-encoding='utf-8' ...
The first ensures that the JSP page is treated as UTF-8, which can represent
all the characters you need. The second ensures that the browser knows that.
Since the browser uses the encoding of the page to send form data,
submissions will now use UTF-8. The third ensures that the container
interprets all submissions as UTF-8.
Other than figuring it out in the first place :-) we have had no problems
with this. We can correctly display, and interpret input, in any language -
Chinese, Japanese, European languages, etc.

Subject: Encodings on form submits?
Folks,
I'm struggling with how to handle form submissions with non-Latin
character
encodings using a Struts action and form beans.
As I understand it, browsers use the character encoding of the form's page
(hex-encoded) for submitting form parameters. I've seen plenty of code to
convert request parameters by hand, e.g.
try
{
return new String(inParam.getBytes(8859_1), encoding);
}
catch (UnsupportedEncodingException e)
{
return inParam;
}
... but this implies that you know the character encoding. Until Servlet
2.3
is standard, you can't just say request.setEncoding ().
So: how to do this in Struts? Ultimately, what I need is my form beans to
have their Strings set properly.
I can think of a few ways.
(1) Let the form bean handle it on set () methods for Strings. Every form
class could extend a base class with a decodeString (), and every form
class
could call this method.
I'm not thrilled about this, since it'd be easy to forget and it's a lot
of
extra coding on every set call.
(2) Modify Struts to do this automatically. This isn't trivial, since the
calls to populate beans
are buried pretty deeply in ActionServlet, RequestUtils, and BeanUtils.
In either case, the handler (whether Struts utils or the beans themselves)
would need to know the encoding to use! The best I can come up with is
that
every form would embed a hidden parameter encoding -- this is how
iPlanet
handles this, they have a j_encoding parameter on forms which tells the
handler how to decode params. (I could modify html:form to do this
automatically, too ...)
Thoughts?
Thanks,
Ben

Re: Error with Data Sources
Okay. I figured out that data-sources needs to go at the tope and I removed the set-property tags and actually made the properties. I am using postgres 7.1 something.

Re: Missing type on declaration - any poniters 1 error left
I think your compiler can't find the initial class declaration. Chances
are your actual syntax error occured before that line. Make sure you
don't have too many '}' and that you're making a valid class
declaration.
It seems that a lot of your problems has more to do with your
understanding of Java than with Struts. You might want to check out
some general java language message groups, as they might be better at
explaining the problems you are experiencing.

RE: Missing type on declaration - any poniters 1 error left
You need to close the brace on your class declaration I believe.

{
try {

servlet.findDataSource(null);
java.sql.Connection myConnection =

//do what you wish with myConnection
} catch (SQLException sqle) {
getServlet().log(Connection.process, sqle);
} finally {
//enclose this in a finally block to make
//sure the connection is closed
try {
myConnection.close();
} catch (SQLException e) {
getServlet().log(Connection.close, e);
}
}
}
} -- Add this brace here

Moving them away from my work mail address is a good thing... So why am I telling you all this? Well I , like Craig T, signed up for several areas on the 1.1 Todo list a while back and like Craig have been busy with work and being away on holiday and training. So keeping up with the volume of mail has been difficult let alone contributing anything constructive. So I, like Craig, am going to have to cut down what I am involved in to make it fair to others and be able to contribute properly without spreading myself too thin. So I am going to back out of the following areas for the following reasons: Standard Validations Client Side Validations - because I have not done the work I expected to in this area and therefore feel I probably shouldn't buttin on these! EJB Design Patterns - for similar reasons. Although I have been working with EJBs I think there are others who are better qualified to lead this piece. I will of course contribute where possible to these areas but feel I am unable to lead them or take a direct role in designing/writing these. Which leaves the following: Multi-page form support - I think this really may tie in with the Workflow processing Workflow processing - I am working on workflow at the moment from a 'backend' perspective i.e. at the EJB layer which I hope will help cement my ideas for the Struts workflow. More on this later. Role-based Action Execution - I have been looking at JAAS and security in general and need to look into the specs a bit more to understand what _must_ be supported by containers and what _tends_ to be supported before we make a decision on exactly where to go withthis. Again more later. I hope this will enable to contribute more than I have in the past and get things moving. Apologies for anyone expecting me to take the others areas through to completion. So on to Workflow. As Ted suggests I also believe the fundamentals are there in the framework already. There have been several discussions about exactly what the workflow piece is but I think Ted's implications are the best. I don't think we are trying to design something that is a GUI nor are we trying to make something that conforms to standards which are in their infancy. This is not to say that support for products ( I think Visio for instance was suggested) should not come later but I think this is in addition to the underlying functionality which is to link Actions together to form a business process with pre- and post-requirements. This is where the thought on the multi-page forms comes in. I have been thinking about this a lot lately and have a few ways of doing this which when I cement them a little more will post here. I think we need to get down a solid set of requirements ( I think Ted's are a good start) and be clear what we are trying to achieve (I have tried to outline my view above) before we can proceed and I will take a proper look at the code examples Ted outlines in his mail. Much of the discussion so far has been on several tracks all under the global term 'workflow'. (Please don't take any of this as criticism - I am aware I haven't contributed much up until now - just observations and an attempt to get this going). So any comments on what we are trying to achieve and how? (and I am waiting for the slap too... ;) And then the security thing I have been primarily working with BEA Weblogic and working on a banking system so security has been key. We have had various discussions with BEA and finally got some answers so I have a clear idea of how BEA do things and how we may be able to fit this in to struts. What is currently not clear and Craig M has alluded to before is that the specs aren't really explicit in this area and each application server tends to do things in its own way. So I intend to look at the specs a little more to see what they should at least all support and then work on whether we want to link something into that or produce a struts specific implementation ( which obviously should abstract things so that people can plug in their app server specific stuff if necessary, although Struts is unlikely, at least at this stage,
