I need something that is consistant between my struts components and the beans and stuff that contain all of my business logic. I'll probably get yelled at for this, but I just use System.err.println() and it works fine with Tomcat. Devon
RE: Mulitpage form support.
When I remove the reset method, I see the behavior that I am looking for. This makes it pretty easy to do mulitpage forms. Thanks for your help. This has also tripped me up and, from the looks of the mailing list archives, many other people. It seems like a good fix would be to have an attibute in the action configuration which indicates whether the input form should be fresh (call reset) or not. Devon
RE: Running the example application that comes along with struts
I have got a problem in running the example struts application. When I run my application , I get the first jsp page , i.e. index.jsp containing MailReader Demonstration Application Options, but when I click on any of the other links, I get this exception , org.xml.sax.SAXParseException: Relative URI struts-config_1_1.dtd; can not be resolved without a document URI. I don't know what this means. Please advise. The format of an XML file is defined by a DTD file. If you have an XML file, you can verify that it is legal by validating it against its DTD defintion. Your error message indicates that your web server is trying to verify the legality of the struts-config.xml file against its DTD file (which is defined at the top of that file). It is having trouble doing so because it can't find that DTD file. The solution to this problem is specific to your web server but it comes up often on this mailing list so maybe the archives could help you. Devon
Q: Struts with EJB's
Hi, I am planning to use struts as presentation framework. All of business logic resides in the form of session and entity beans. I want to initialise ejb homeobjects at the start of action servlet. Can anybody tell me to have optimum approach to do this.

Handling exceptions thrown from Action.perform in the errorpage?
Hey there!
I have a question for you guys.
When an exception is thrown in my Action derivative I want that exception
to
be handled by the errorpage (%@ page isErrorPage=true %). After fooling
around
with the web.xml file adding entries such as:
error-page
exception-typejavax.servlet.ServletException/exception-type
location/errorpage.jsp/location
/error-page
the result is that when I throw a ServletException from the Action.perform
method
I'm directed to my login page(?!). I've tried using the
mapping.findForward approach,
as in:
public final ActionForward perform(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
ActionForward af = null;
try {
af = doPerform(...); // throws exception
} catch(Throwable t) {
request.setAttribute(javax.servlet.jsp.jspException, new
ServletException(t));
af = mapping.findForward(error);
}
return af;
}
ofcourse, I added:
!-- == Global Forward Definitions
== --
global-forwards
forward name=errorpath=/errorpage.jsp/
/global-forwards
to the struts-config.xml file.
That didn't work either. The only approach that seems to work for me is:
public final ActionForward perform(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
try {
return doPerform(...); // throws exception
} catch(Throwable t) {
request.setAttribute(javax.servlet.jsp.jspException, t);
getServlet().getServletContext().getRequestDispatcher
(/errorpage.jsp).forward(request, response);
}
}
Now my questions are:
Is this last approach safe to use with Struts?
How do you guys accomplish this? Do you use a different approach
altogether?
TIA,
S. Bro

Re: Handling exceptions thrown from Action.perform in the errorpage?
global-forwards
forward name=errorpath=/errorpage.jsp/
/global-forwards
return mapping.findForward(error)
Will forward to the file named errorpage.jsp in the root of your Web
application.
If it doesn't, something else is wrong, like doPerform is not throwing
the exception (Try logging it too.), or the page is in the root of your
container instead, et cetera.
Meanwhile, when saving exceptions for display on a JSP, you might use
Action.EXCEPTION_KEY
for the attribute key. The custom tags use this, and so your page would
also display any exceptions the tags throw. (See saveException() in
util.RequestUtils)

Re: Workflow impasse? New ideas.
As it stands, the Struts ActionMappings are already very nearly workflows. To close the loop, I believe we only need a few things. 1) A way to declare prerequesite actions. 2) A way to bookmark an Action, so the workflows can be rentrant. 3) A way to declare the html:form Action path at runtime. Given these capabilities, and a simple support structure, a set of ActionMappings can be linked together to form a robust workflow that can reuse input forms. Matthias Bauer has code for (1), http://www.mail-archive.com/struts-dev@jakarta.apache.org/msg01685.html and Martin Cooper has a plan for ActionRequests that sound good for (2). http://www.mail-archive.com/struts-dev@jakarta.apache.org/msg02398.html As for (3), I have a hack in place now, http://www.mail-archive.com/struts-dev@jakarta.apache.org/msg02374.html but was waiting on Martin's ActionRequests before thinking seriously about integrating the mechanism into the framework. Craig is also reviewing some airplane notes http://www.mail-archive.com/struts-dev@jakarta.apache.org/msg02439.html he has about a scripting mechanism that might also be used for workflows. In the end, I think a workflow will look like another set of ActionMappings, and the Action will just contain some extra logic for returning the correct ActionForward if the flow gets out of synch. In the meantime, I do like the ideas that are coming up on this thread. Jonathan Asbell wrote: Hello all. I just got back and was reading the e-mails about workflows. By the tone and lack of dialog I think that we are not sure how we really want to design workflows still. So lets have more discussion on the subject. When its clearer we will better know what we want to do.
RE: code reuse
The previous response was thought provoking and may answer my specific concerns, but I don't see my way through the issues yet. Let me be more specific so that we can dive into the issues that I face: Currently, we have developed a full featured demo with two main wizards - 1) Account Maintenance (4 screens) 2) Order Management ( 8 main screens with ~20 minor screens) We have an Account Maintenance Form (about 50 properties) and an Order form (about 250 properties). Each Account Maintenance screen has its' own Action class feeding a segment of the Account Maintenance Form. The Order Management wizard has one main Action class with a couple of helper classes to manage the 8 main screens (work flow) all feeding the Order Form. The Order Form is also feed by a the 20 minor screens which each have their own small Action class. One of the minor Order screens is the Corporate Info screen (mainly address info)- it is designed to be a popup screen that can be called from within the Order wizard or the Account Maintenance wizard. However, it isn't implemented as an independent Action/Form because we don't know how to make the Order Form AND the Account Mntc Form both reuse the Corporate Info Form/Action. Specifically, we don't know how to implement such that the Action class for Corporate Info can be reused by both the Order and Account wizards. So, today the same fields are duplicated in the two wizards and all the code is duplicated (ugly!). We can envision a wrapper form that contains other forms and uses a dot notation in the JSPs to reference properties (orderForm.corporateInfoForm.address) but how do the Action classes for CorporateInfo get reused? There seems to be such tight coupling between an ActionForm and an Action Class that I don't know how to achieve reuse. I played with creating an IAddress Action interface that both the Order and Account wizards could implement but got caught up in the coupling issues. Thanks! ...Steve -Original Message- From: Ted Husted [mailto:[EMAIL PROTECTED]] Sent: Sunday, July 22, 2001 3:19 PM To: [EMAIL PROTECTED] Subject: Re: code reuse I would say that if you have one EJB for all these properties, then you should have one ActionForm as well. The trick to ActionForm reuse is the validation method. If the class is used on more than one form, then validate() may need to address a different set of properties. If you are using the ValidatorForm, it has a page property. Each formset can have its own page name, and can validate only the properties relevant to that formset. Otherwise, validate() is passed the ActionMapping, and you can use that to determine your own form sets. Some developers also use hidden fields for the same purpose. Of course, if only one form is used for data-entry, validating more than one form may not be an issue. Once you have an ActionForm that you can use on more than one form, you can also use the same Action to handle them all. Since Actions are multithreaded and cached by the framework, fewer Actions can mean a better deployment. I'm often tempted to try designing an application around a single ActionForm and Action. This may make for a more efficient Struts application, but may also lead to maintenance issues. In general, I tend to design my applications around packages or modules. The package may offer several operations and JSP views, but use only one Action and ActionForm for them all. My favorite way to use an Action with several operations is to use a separate ActionMapping for each. An easy way to tell one mapping during processing from another is to use the parameter property to give each a logical name. action parameter=select path=/donor/Search type=org.wxxi.gavel.donor.http.Client name=donorForm scope=request validate=false forward name=continue path=/WEB-INF/pages/donor/Result.jsp/ /action action parameter=select path=/donor/View type=org.wxxi.gavel.donor.http.Client name=donorForm scope=request validate=false forward name=continue path=/WEB-INF/pages/donor/View.jsp/ /action In perform() or validate(), you can call mapping.getParameter(), and call the appropriate operation. The parameter property was originally introduced to support the optional DispatchAction class. This uses reflection to call a different perform() method for each operation. This is a nifty feature, and I do something similar by subclassing Actions and giving the ancestors a utility method to handle stadnard operators, across a package or even the entire application. The current DispatchAction expects the Action to be called using a syntax like http://localhost:8080/myapp/saveSubscription.do?method=update where method is set as the parameter property. The Action then dispatches this call to a public method with the signature public ActionForward update(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException As
Re: How to integrate flash request into struts ...
Since loadVariables is an internal flash call, I imagine the problem will most likely be in flash, and not with JSPs. What you can try is to reconfigure your mappings so that *.asp will be treated as a JSP, and rename your JSP files to *.asp. If this works, it means flash (or the flash host - IE or other flash runner) is doing some extension processing and doesn't handle the jsp extension properly. Another thing to check is that the HTTP headers written when using the JSP solution is comparable to what the working CGI or ASP solution is writing. Good luck.

To do that i connect to a jsp file and pass variables in the http header (just as any HTML form) to the jsp. My problem is the jsp file redirect the swf to the jsp and load the jsp in place of the swf. Can you help? Are there a way to connect and read to the jsp script without reloading the page just as I can do with ASP??? This trick work fine with ASP,CGI and other.

[answer to the question] how to access beans collected in hashtable?
Hi, who knows how to iterate a hashtable and access its value-objects (beans with some properties)? I can reach the beans in the hashtable: logic:iterate id=element name=myhashtable property=table/ bean:write name=element property=value/ /logic:iterate But I don't know how to reach the properties of the beans. Any idea?? --- Yeah, just before I pressed the send butten we got it! ---: logic:iterate id=element name=myhashtable property=table/ bean:write name=element property=value.name/ /logic:iterate Cheers Hartmut
what setters do i implement in an indexed tag ?
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.

Everything works correctly at this point. Then editfund.jsp has a form that has action mapped to updatefund action and also has an cancel button. If cancel button is pressed the updatefund action gets executed, am I right?

Re: code reuse
From your description, it sounds like there could be an ancestor ActionForm common to the Order and Maintenance wizards. If that were the case, each could subclass that ActionForm, and the Corporate Info Action would then refer to the ancestor class, common to both wizards. In general, an Action does not need to be tightly coupled to a particular ActionForm. In fact, the coupling is rather loose. The Action itself is passed a reference to an ActionForm. Which ActionForm class is passed depends on the ActionMapping. There ~is~ a tight coupling between an ActionMapping and an ActionForm class, but the Actions themselves can be reused -- though some clever typecasting may be needed if more than one ActionForm class is accessed. It's important to remember that an Action can be used by any number of different ActionMappings. Whether or not they use the same ActionForm is up to the developer. The framework's design allows you to use a a different Action for each ActionForm, or a single Action for the entire application, or anything in between.

However, it isn't implemented as an independent Action/Form because we don't know how to make the Order Form AND the Account Mntc Form both reuse the Corporate Info Form/Action. Specifically, we don't know how to implement such that the Action class for Corporate Info can be reused by both the Order and Account wizards. So, today the same fields are duplicated in the two wizards and all the code is duplicated (ugly!). We can envision a wrapper form that contains other forms and uses a dot notation in the JSPs to reference properties (orderForm.corporateInfoForm.address) but how do the Action classes for CorporateInfo get reused? There seems to be such tight coupling between an ActionForm and an Action Class that I don't know how to achieve reuse. I played with creating an IAddress Action interface that both the Order and Account wizards could implement but got caught up in the coupling issues.

Re: Mappings, bloody mappings
All the local forwards I see refer to funds.do -- but I do not see an ActionMapping for funds. There is a forward for funds, but that would not map to funds.do internally. The one you have marked as also tried looks all right though. I may be a typo, but your message mentioned an UpdateAction, but the type specified is FundUpdateAction. I'd also try running it under a development copy of Resin or Tomcat 4, which may give you more information with the error message. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 737-3463. -- http://www.husted.com/about/struts/ Aapo Laakkonen wrote: I have problem...

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

Initializing Application Scope Attributes *.do in template:put
Hi, perhaps these are FAQ: 1) My application has menu structure configurable in the database. I want to read the structure from the database when the app starts and store it in an application scoped bean. To be able to read the data, I need a DataSource so I need access to actionServlet. What is the best way to do this? I know, I can use my own servlet inherited form ActionServlet - but is there any ohter, perhaps more configurable way? 2) When I need initiazed data in my application, I usually put the initialization into setServlet of the action which needs the data and I thought never to need to access such data from a JSP directly. But now I've found this problem when creating menus. I've created a MenuForm which holds the information about the current location id and a collection of menu's children. MenuAction reads the id and fills the children collection, checking whether the current user should see the menu items. menu.jsp then displays the menu structure from MenuForm. It works perfectly, till I try to put this menu into another JSP via jsp:include ... or template:put content=/menu.do?id=100 The problem is that my MenuAction does not produce the HTML, it *forwards* it to the menu.jsp. And forwardning seems to be forbidden inside an include. (Err: Cannot forward as OutputStream or Writer has already been obtained) Is there a way, how to include a *.do generated page which internally uses forward? (Actually, this could be probable solved with the workflows. The action actually does not have to forward to the jsp. I just need to let it perform and include the jsp then) -- gR
Re: Struts + JBoss
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...
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...
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

Re: Another question about the logic:iterate tag
The docs say JSP bean, but the meaning there is broad. So, yes, you can do this: request.setAttribute(hashmap,hashmap); ... logic:iterate name=hashmap To use an actual bean, you would also specify the property logic:iterate name=javaBean property=hashmap which resolves to javaBean.getHashmap() Melissa wrote: Hi again. I am wondering whether the logic:iterate tag requires you to use a bean (or bean property) as the collection to iterate over. I would actually like to iterate over a hashmap that i placed in the request in my action class, but I have not determined through the user docs whether this is possible or not.

I have fundlist action that displays all the funds, ok. Then when user selects one fund on the list struts executes editfund action and gets all needed information about that fund. Everything works correctly at this point. Then editfund.jsp has a form that has action mapped to updatefund action and also has an cancel button. If cancel button is pressed the updatefund action gets executed, am I right? Here is first two lines from UpdateAction class: if (isCancelled(request)) return (mapping.findForward(cancel)); Then it should go back to fundlist.do action, but all what I get is HTTP 400 Bad Request error. What I am doing wrong? Or should I do something different to get the same results? And I'm running struts on Apache Test Environment 3.2.1 for Visual Age 3.5.3.

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. Hi, I use struts in jboss+tomcat. I use 2 configurations: 1st) Separate ejb and war. There are no problems, since I have no EAR file. 2nd) An EAR file. This is a bit tricky: a) you have to let struts.jar in the root of the EAR. Do not place it under war/WEB-INF/lib. Do the same with all jars which would go into WEB-INF/lib b) in war's META-INF/manifest.mf you need following lines for needed libraries: Class-Path: ./struts.jar Class-Path: ./somethingelse.jar So far so good. ActionServlet will be found, your Actions as well But I've had problems with Jasper. It was not able to compile my JSP pages, since it was not loading the jars from manifest.mf The solution was to use jasper at deployment time and let it to compile all jsp pages into java, compile those java sources into classes, jar them and put the jsp.jar into my EAR along with the modified web.xml Even with ant it is not so easy and the deployment takes a lot of time. So I use the 1st approach during development. -- gR

HIT PAY DIRT! Re: Baisc q 2 Cannot find message resources u/key -
Jon, When you posted the version of the xerces compiler you were using ***xerces 1.3.1***, that solved my problem. Here's the link guys: http://xml.apache.org/dist/xerces-j/ Get xerces1.3.1.zip from the link above and do like Jon said in his original message. Remove the other XML parsers from your classpath (I had JAXP mucking things up), then get xerces.jar out of the zip file that you download, and place it in the Tomcat/lib directory. Make sure to update catalina.bat in Tomcat/bin to setup your runtime classpath. Mine looks like: set CP=%CATALINA_HOME%\bin\bootstrap.jar;c: \tomcat\lib\xerces.jar;%JAVA_HOME%\lib\tools.jar;c: \tomcat\webapps\struts-example\WEB-INF;c: \tomcat\webapps\struts-example\WEB-INF\lib\struts.jar Thanks!

Re: Baisc q 2 Cannot find message resources u/key -
it looks like you need to remove crimson.jar from your classpath
still...maybe it's in the system classpath before you start tomcat?? struts
does not like anything but xerces 1.3.1, for some reason, in the newer

load, it seems to get caught in a loop.. Still no joy, but at least
something different is happening.

Please

Hi, there only promlem is that i am not running tomcat 4.
i know that... :-) ok...let's try this worded a different way:
the problem is an xml parser issue, as this question has come up a lot
lately and i got my own servlet container to work by carefully analyzing
where and when my xml parsers were getting loaded...
your solution will *obviously* be different, but the problem seems to come
from classloading of xml parsers...you'll of course need to look through
your lib directories and make sure no other jaxp or crimson parsers are
there, replacing them with xerces 1.3.1 (1.4.1 will also give some issues
with some containers, specifically tomcat)...
i was only using my solution as an *example* of how everyone having this
problem can analyze their own servlet container to help fix the problem.
i
was getting pretty irritated because NO ONE was helping me fix this
problem,
or even offering constructive advice on the deeper issue i knew it had to
be...one deeper than just making sure my config files were accurate...
it's something worth trying, anyway...

RE: Another question about the logic:iterate tag
I have just tried this, but the id attribute is apparently required. My
guess is that this can just be an arbitrary variable... However, the bigger
issue seems to be that the iterate tag isn't really suited to the retrieval
of more than one oject (i.e. the hashmap's key/value pairs)...
here's the old code I was hoping to convert:
!--% HashMap jmap = (HashMap)request.getAttribute(hmap);
for (Iterator i = jmap.keySet().iterator(); i.hasNext(); ) {
String key = (String)i.next();
Object obj = jmap.get(key);
%
tr
tdfont size=1%= key %/font/td
tdfont size=1%=
obj.toString()%/font/td
/tr--
%
}
%
Is there a way to integrate this into a Struts iterate tag, or should i just
stick with the original code?
Thanks so much for your help.

Subject: Re: Another question about the logic:iterate tag
The docs say JSP bean, but the meaning there is broad. So, yes, you
can do this:
request.setAttribute(hashmap,hashmap);
...
logic:iterate name=hashmap
To use an actual bean, you would also specify the property
logic:iterate name=javaBean property=hashmap
which resolves to javaBean.getHashmap()

RE: what setters do i implement in an indexed tag ?
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.

Subject: what setters do i implement in an indexed tag ?
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.

html:form scripting variable
Hi, why does html:form generate no scripting variable? Would be nice, if it did. -- gR
RE: what setters do i implement in an indexed tag ?
Ignore my previous post because I was mistaken. You don't need a setXYZ(int
index, XYZ x) method because struts will call the public XYZ getXYZ(index
i) method and then call the appropriate set method on the bean that is
returned. This worked for me (with last nights CVS):
logic:iterate id=interestRate name=editInterestForm
property=interestRates
tr
tdhtml:hidden indexed=true name=interestRate
property=interestRateId/
html:text indexed=true name=interestRate property=monthId/
/td
tdhtml:text indexed=true name=interestRate property=rate size=5
maxlength=5/ /td
/tr
/logic:iterate
which generates field names like interestRate[0].monthId
so struts will call form.getInterestRate(0).setMonthId(somevalue)
I had this in my form class:
ArrayList interestRates; // initialized in constructor and reset()
public InterestRateJBean getInterestRate(int index)
{
if (index interestRates.size()-1)
{
interestRates.add(index,new InterestRateJBean());
}
return (InterestRateJBean) interestRates.get(index);
}
Again, I just got this to work so I may be missing something.

Re: code reuse
In my first attempt, I think that I got caught up in the clever typecasting may be needed if more than one ActionForm class is accessed problem. I'm trying to design a template for a few generic reusable Action classes ( Corporate Info, Contact Info, Location Info ). I'll work up a simple prototype to identify what I'm missing. Thanks...Steve - Original Message - From: Ted Husted [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, July 24, 2001 9:25 AM Subject: Re: code reuse From your description, it sounds like there could be an ancestor ActionForm common to the Order and Maintenance wizards. If that were the case, each could subclass that ActionForm, and the Corporate Info Action would then refer to the ancestor class, common to both wizards. In general, an Action does not need to be tightly coupled to a particular ActionForm. In fact, the coupling is rather loose. The Action itself is passed a reference to an ActionForm. Which ActionForm class is passed depends on the ActionMapping. There ~is~ a tight coupling between an ActionMapping and an ActionForm class, but the Actions themselves can be reused -- though some clever typecasting may be needed if more than one ActionForm class is accessed. It's important to remember that an Action can be used by any number of different ActionMappings. Whether or not they use the same ActionForm is up to the developer. The framework's design allows you to use a a different Action for each ActionForm, or a single Action for the entire application, or anything in between.

However, it isn't implemented as an independent Action/Form because we don't know how to make the Order Form AND the Account Mntc Form both reuse the Corporate Info Form/Action. Specifically, we don't know how to implement such that the Action class for Corporate Info can be reused by both the Order and Account wizards. So, today the same fields are duplicated in the two wizards and all the code is duplicated (ugly!). We can envision a wrapper form that contains other forms and uses a dot notation in the JSPs to reference properties (orderForm.corporateInfoForm.address) but how do the Action classes for CorporateInfo get reused? There seems to be such tight coupling between an ActionForm and an Action Class that I don't know how to achieve reuse. I played with creating an IAddress Action interface that both the Order and Account wizards could implement but got caught up in the coupling issues.
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).

I think I found a solution to the problem, but I'm not sure why it worked. It was my understanding that websphere didn't look at the web.xml file so I didn't have one.

Uploaded file get corrupted after migrating to Struts 1.0
We have recently switched to Struts 1.0 from a previous beta version. After migrating we are having problems in uploading certain files. The files do get uploaded to the server but the contents get corrupted some times. We further investigated this problem and found out that files get damaged when they contains non-English content. For example if we upload a Microsoft Excel file, that contains non-English characters, it got corrupted and we are unable to process that file with MS Excel. The problems disappears if we switch back to old struts.jar file. Any ideas how to fix this problem. Is it safe to replace the struts.jar file with old one as in interim solution?.

The Struts tags often throw exceptions, but I don't believe any write to
a log. They do record the Exception in the request context though, so it
can be reported elsewhere (e.g. an JSP error page). Here's an example
from interate:
else {
JspException e = new JspException
(messages.getMessage(iterate.iterator));
RequestUtils.saveException(pageContext, e);
throw e;
}
The messages for the exceptions are in
taglib\logic\LocalStrings.properties .
Sorry I could help with committing the indexed tag, but I haven't had a

RE: Another question about the logic:iterate tag
Yes - yes, and again, yes. Thanks, Ted.
To further expound (in the chance that it might help someone else), when one
needs to iterate through the key/value pairs of a hashmap, instantiate the
object as type Map:
Map aMap = new HasMap();
and place it in the request. When you need to retrieve the elements, you
can save time by using the struts logic:iterate tag as follows:
logic:iterate name=map id=mapEntry scope=request
bean:write name=mapEntry property=key/
bean:write name=mapEntry property=value/
/logic:iterate
This works b/c the element that gets exposed as the iterator is actually a
Map.Entry object, which contains the key value pairs as properties (although
this utility is only available during the life of the iteration).
Very useful! It reduced my code from a natty 11 lines (see below) down to 4.
Feeling *much* better now,
Melissa

The docs say JSP bean, but the meaning there is broad. So, yes, you
can do this:
request.setAttribute(hashmap,hashmap);
...
logic:iterate name=hashmap
To use an actual bean, you would also specify the property
logic:iterate name=javaBean property=hashmap
which resolves to javaBean.getHashmap()

chaining actions
I have two Actions chained together and my appserver is throwing core dumps on me left and right if I issue too many repeat requests. Here are the mappings: action path=/changeTree type=com.yyy.zzz.ChangeTreeAction forward name=nextViewpath=/viewTree.do/ /action action path=/viewTree type=com.yyy.zzz.RetrieveTreeAction scope=request validate=false forward name=showTree path=/generic_treeview.jsp/ /action So I have a jsp that shows a tree. When the user clicks on one of the nodes, the /changeTree request is posted to the ActionServlet. The ChangeTreeAction modifies the tree and then forwards onto the RetrieveTreeAction which forwards back to the jsp view of the tree. My actions use a TreeManager SFSB so I had to synchronize in order to prevent multiple requests from hitting the same SFSB. If I issue too many requests the app server crashes (threads are locking I believe). The perform method in each of the Actions are synchronized. Since the request flow is *always* from ChangeTreeAction to RetrieveTreeAction, I don't see how deadlock can be happening. NOTE: I thought maybe it was some of my code in the perform method so I stubbed out both perform methods to only print a line to the console and it is still happening. If I remove the synchronized blocks, it is all fine. Is there a better way to chain actions? Has anyone experienced anything similar?

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 by new objects the next time. This didn't seem
to
affect the observable behavior of the struts example application.
the question(s):
We really, really want to use struts on WAS 4.0. There seems to be some
logic within struts that relates to null attributes.
What are the architectural implications of running an app built upon
struts
that will never have it's attributes removed from request scope?
If there are implications, are there ways to work around the problems?
Is it feasible to extend the struts framework to specifically target the
changes noted in WAS 4.0? If so, do you have any recommendations how to
go
about doing this?
Thank you very much,
Mark
Design Q - Select List Data of possible values of a business object attribute
Good Afternoon... I have a design issue that I am tackling with how to deal with in the struts framework. I have a Shipment class that can have multiple Container objects. Each Container object has an attribute 'typeID' (int) which can have 1 of the following values: 1,2,3,4,5 (as well as other attributes such as size, width, size, number) I have a database table, Container Types, that stores these values and related text descriptions (ID, Desc). The user interface (web) will access the data contained in the Shipment and Container objects. I need to present the user with a select list of the possible options for container type, such that the user sees the descriptions, however the ID is the value that is used to update the object. My questions are: 1. How/Where do I access this 'list' of data that I need for the UI? Do I have a method as part of the Container class to return these values? Do I create a separate utility class? Do I create a collection of objects that represent a 'container type'? I am torn on this issue... 2. Is there a good way to do this while utilizing the struts html tag library? Thanks in advance for any feedback you can provide! Mary Jo

Tomcat/Struts Design Issues and Questions
Struts-users! Sorry if this is not the best forum for this; I am asking this here becuase I think Struts factors into my question. I am creating a web site that allows for the future addition of new webapps to extend the original site. I would like to allow users to make their add on as a full webapp, and I'll store the link to the new webapp in my database. One of the requirements I have is that I need to pass my session onto the new webapp. But, oops, you can't do that. Tomcat (and the Servlet API) doesn't let you pass a session to a new webapp - as far as I can tell. I could pass the important tidbits as strings along in the URL and recreate a session once I get to the new webapp, but that has its own set of problems...it's insecure (no matter how i encode the URL), and it completely messes up the first webapp, becuase when I return to that webapp the session will probably have timed out. Does anyone know of a way that I can maintain a list of trusted webapps which I can pass session between? How about if there is a way to deploy an entire webapp within the context of another? I don't want future developers to need to mess with my code to get their apps into my context. And here is the STRUTS part of my question. If I allow future developers to simply put all of their JSPs/images/templates/etc. into a subdirectory in my webapp, is there a way to allow them to either add their own struts-config.xml file or make struts reread the struts-config.xml file while Tomcat is still running? I also have a requirement of leaving the server running while i deploy so that i don't lose sessions. Any thoughts would be welcome and appreciated. I have looked through archives for Tomcat and Struts and can't seem to find an answer. Thanks in advance! Becky _ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp

Hi everyone,
I wanted to clarify the status of Struts and Websphere 4
compatability. As a business partner to IBM, we are on the beta testing
program for Websphere 4.0 . This particular issue was brought to their
attention a couple of weeks ago. Last week we received word that it has
been fixed in the latest beta build and will not be an issue in the

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 by new objects the next time. This didn't seem
to
affect the observable behavior of the struts example application.
the question(s):
We really, really want to use struts on WAS 4.0. There seems to be some
logic within struts that relates to null attributes.
What are the architectural implications of running an app built upon
struts
that will never have it's attributes removed from request scope?
If there are implications, are there ways to work around the problems?
Is it feasible to extend the struts framework to specifically target the
changes noted in WAS 4.0? If so, do you have any recommendations how to
go
about doing this?
Thank you very much,
Mark
Validation Framework: html tag required for form elements
For the validation framework to operate, is it necessary that struts tags are used to write out form fields? Or is it possible to use plain html?

Re: Validation Framework: html tag required for form elements
It isn't necessary for struts to write out the field as long as the name of the input matches the property name of the field. So in your example you would have a getValidateMe method. I'm assuming your still going through an Action (if not you can still get it to work, but you will have to change some things).

Refresh button and Back button
I'm sure many of you have run into these problems before: 1. My form is stored in the session, when the user updates, it goes back to a list screen, the SaveAction servlet removes the form from the session. PROBLEM: A NullPointerException is thrown when the user clicks on the back button. 2. When a user saves a form, they return to the list screen, PROBLEM: Another record gets added to the database. Is there anyway in struts to manipulate the header so the back and refresh think the last page was the current page? Can I do this in the SaveAction servlet?

Re: Refresh button and Back button
Basically, the problem is with browsers' caching. For example, IE will ignore header settings you sent. In several references you will find methods to set headers, but they all ignore to recognize that it is after all the browser that decides and/or ignores. Back buttons are developers' nightmare. --- Matt Raible [EMAIL PROTECTED] wrote: I'm sure many of you have run into these problems before: 1.

Empty Page returned after Action executed
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. And... it also does not work if I specify forward as shown below: action path=/shipsum type=com.mim.pilot2.SummaryAction name=summaryForm scope=request input=/shipsum.jsp forward name=success path=/shipsum.jsp/ /action But... if I use the entry: action path=/shipsum forward=/shipsum.jsp / shipsum.jsp is displayed correctly. Under what conditions does Struts return an empty HTML page? Can someone spot my error?
