Struts-example database
I just downloaded struts 1.1 binary and loaded the struts-example into tomcat and it works fine. My question is I do not understand when and how the database is loaded in the index.jsp. There is a tag that reads: logic:notPresent name=database scope=application But I do not see the database name in the struts-config or web.xml file. In the tour.htm file it talks about a DatabaseServlet that I can not seem to find (I guess it was takin out). Thanks for the help, Derrick (Sorry if this is the second time you received this message.

Re: DynaForm Beans and Indexed Text fields.
Okay, so I set the scope of both the preload action, and the action servlet that my form is bieng posted to, to session. I also put the bean in session scope instead of request scope when I preload the DynaForm with values before passing it to the jsp. So The jsp still loads and reders the indexed text fields just fine.. but now I get this exception when I submit the form: java.lang.ClassCastException at org.apache.struts.util.RequestUtils.createActionForm(RequestUtils.java:688) at org.apache.struts.action.RequestProcessor.processActionForm(RequestProcessor.java:359) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:253) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1420) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:520) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.doFilter(Unknown Source) at org.apache.catalina.core.StandardWrapperValve.invoke(Unknown Source) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source) at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source) at org.apache.catalina.core.ContainerBase.invoke(Unknown Source) at org.apache.catalina.core.StandardContextValve.invoke(Unknown Source) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source) at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source) at org.apache.catalina.core.ContainerBase.invoke(Unknown Source) at org.apache.catalina.core.StandardContext.invoke(Unknown Source) at org.apache.catalina.core.StandardHostValve.invoke(Unknown Source) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(Unknown Source) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source) at org.apache.catalina.valves.ErrorReportValve.invoke(Unknown Source) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source) at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source) at org.apache.catalina.core.ContainerBase.invoke(Unknown Source) at org.apache.catalina.core.StandardEngineValve.invoke(Unknown Source) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source) at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source) at org.apache.catalina.core.ContainerBase.invoke(Unknown Source) at org.apache.coyote.tomcat4.CoyoteAdapter.service(CoyoteAdapter.java:223) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:594) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:392) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:565) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:619) at java.lang.Thread.run(Thread.java:534) Apache Tomcat/4.1 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Generic Ok/Cancel Page
Hi I am wishing to create a generic OK/CANCEL type page that can be used by different workflow situations. Can anyone suggest a nice tidy way of doing this? The way I see it is that somehow I need to dynamically define the ok/cancel forwards from the page based on the page it is coming from.

Re: validation, input page, and request-scoped variables
That makes perfect sense now. Another action mapping that sets up the rest of the page variables but doesn't touch the form. I'll do it like that, of course making sure that the common parts (setting up the request attributes) is in one method that gets used by all. Thanks! On Sunday, Aug 24, 2003, at 06:38 Canada/Eastern, Adam Hardy wrote: Ah, I see I missed out a bit of the logic. My action class has a part that is executed for every action mapping, which fetches the necessary related data, such as dropdown lists (but not the actual object's properties). What else the action does is dependent on the result of a bit of logic which is executed after the mandatory processing mentioned above. I'm having problems describing it, perhaps it's easier to understand just looking at the xml: actionpath=/secure/startSectionInsert type=org.blacksail.linklib.section.SectionAction name=sectionForm scope=request validate=false parameter=blank roles=user set-property property=secure value=false/ forward name=finished path=.section/ /action actionpath=/secure/startSectionUpdate type=org.blacksail.linklib.section.SectionAction name=sectionForm scope=request validate=false parameter=display roles=user set-property property=secure value=false/ forward name=finished path=.section/ /action actionpath=/secure/sectionUpdate type=org.blacksail.linklib.section.SectionAction name=sectionForm scope=request validate=true parameter=save input=/secure/sectionValidateFailed.do roles=user set-property property=secure value=false/ forward name=failed path=.section/ forward name=displaypath=/secure/startSectionUpdate.do/ forward name=finished path=/secure/library.do redirect=true/ /action actionpath=/secure/sectionValidateFailed type=org.blacksail.linklib.section.SectionAction name=sectionForm scope=request parameter=finished roles=user set-property property=secure value=false/ forward name=finished path=.section/ /action Both insert and update submit to update. The last mapping there just does the mandatory getting the required dropdown lists. HTH Adam On 08/24/2003 02:13 AM ll wrote: Thanks for the reply. So in your save action your form input is the action that sets up the form. Meaning that in your struts-config for the save action you have input=/edit.do or input=/add.do...? Which one do you choose? Also, as I understand it, this can only work if the action doesn't set any of the form fields. Do your actions set any form fields? If not, then I guess you can always use the add action. But in my case the add action sets some values (for example to preselect a default item in an options list), and of course the edit action also sets values (it looks up the values from the database). So after submitting, if the validation fails, the form field values are changed, they are not what the user just typed. Or am I misunderstanding something? Thanks...

In my add, I set the id to 0, so on save, it knows that this is an add and not an edit. I had to make a decision not to allow 0s as ids in the database. Possibly I could have used a negative number instead, as long as it validates. Adam On 08/23/2003 07:29 PM ll wrote: Here's my problem: I have a form page that uses some request-scoped attributes for some things it shows on the page (other than the form field data). I always access the page through an action which sets up the attributes. But if validation fails when I submit the form, then those request attributes no longer exist because the input forwards to the jsp page without going through the action again. Two possible solutions: 1. On the save action, use input=/person/add so that when validation fails control is forwarded back through the action, which can then set up the request attributes again. - problem: I use the same page from an edit action, which takes a person id parameter and pre-fills the form. If I do it this way I will need two save actions, one that uses the edit page as the input and one that uses the add page as the input. Then the form can't be shared, because I the submit action will need to change depending on whether it is an add or an edit. 2. Store the attributes in the session instead of the request. - problem: if the user has two browser windows open to the same form then the values displayed in the page could be wrong
Re: Generic Ok/Cancel Page
I have a generic confirm page (it just tells the user that the action was completed, i.e. their data was saved), but I'm sure you could use the same idea. In my submit action (the one that handles the form submission), I have two forwards: forward name=confirm path=/WEB-INF/jsp/confirm.jsp/ forward name=continue path=/app/setup/normalUser redirect=true/ confirm is the confirmation page, and continue is where the user should go after the confirmation page. In my action: // find the continue ActionForward, and save it's path in the request ActionForward continueAf = mapping.findForward(continue); WebUtil.setRequestAttribute(request, continuePath, continueAf.getPath()); return mapping.findForward(confirm); and in the confirmation jsp page there is a continue link: html:link hide=true page=%= (String) request.getAttribute(continuePath) % bean:message key=common.continue/ /html:link Instead of just a continue forward, you could have two: ok and cancel. Then in the action store them both in the request, and the jsp page could have two links. Hope that helps.

RE: Struts-example database
The example application defines a custom plug-in that is initialised at start-up and loads the database and stores it in the ServletContext (application scope). struts-config.xml: plug-in className=org.apache.struts.webapp.example.memory.MemoryDatabasePlugIn set-property property=pathname value=/WEB-INF/database.xml/ /plug-in MemoryDatabasePlugIn.java servlet.getServletContext().setAttribute(Constants.DATABASE_KEY, database); Constants.java public static final String DATABASE_KEY = database; Plug-ins are a common way to initialise application resources.

Re: How to dynamically decide the properties of the DynaValidator/DynaActionForm
Adam, Even, i know the nature of all the attributes during design time itself. Assume, i have 50 attributes in general, i know how to validate each one of them, during design time. But, for a particular kind of Business object, i would be getting just 20 properties alone, and the rest of the properties will not be applicable to the business object. Thats why i was facing problem, while contructing the bean. I think, with struts-validator, i can define all the possible rules for the bean. I have to give a try ...

Re: How to dynamically decide the properties of the DynaValidator/DynaActionForm
Mark,
This approach looks nice. Did you consider, populating the bean, on form
submit ? ... one more thing is.. will the struts-validator go well with
this ?

Mark Lowe wrote:
Okay .. I've been thinking about this.
I think it might work something like this..
form-property name=beans property=java.util.ArrayList /
The arrayList will be a container for your beans with indexed
properties.
So in jsp we're thinking, or aiming for
logic:iterate id=bean name=myForm property=beans
bean:write name=bean property=key[%= index %] /
html:text name=bean property=value[%= index %] /
/logic:iterate
So we have a bean thats mapped backed, or something here's some
pseudo code.
public class MyBean {
private Map map;
public Object[] getKeys() {
return map.keySet().toArray();
}
public Object[] getValues() {
ArrayList list = new ArrayList();
Object[] keys = getKeys();
for(int i = 0;i keys.length;i++) {
String value = map.get(keys[i].toString());
list.add(value);
}
return list.toArray();
}
public String getKey(int i) {
return keys[i].toString();
}
public String getValue(int i) {
String key = getKey(i);
return map.get(key);
}
public void setKey(int i, String str) {
keys[i] = str;
}
public void setValue(int i , String str) {
map.put(getKey(i),str);
}
...
well you get the idea..
Am I tree barking, smoking crack or something but Its starting look
possible.. el should help move the scriptlets out, but using indexed,
mapped properties looks like it may do the job.. the bean could have
a double sided array it returns to keep the keys and values in the
correct order. The keys are after all the illusion that the
properties have names, when really they are associated via index.
When it comes time to write to a db or something the bean could
return a map and the key=value pairs should all be there ready.

you old one and then add some new stuff..
DynaActionForm oldForm = (DynaActionForm) form;
//get the map out and mess with this and life should be simpler
that using the dynaBean
Map oldFormMap = oldForm.getMap();
oldFormMap.put(statusChangeTime,A new Time);
DynaActionForm newForm = new DynaActionForm();
BeanUtils.populate(newForm, oldFormMap);
If this doesn't work you can try constructing all you dyna
properties, having a DynaProperty[] array and then use the
dynaBean constructer that takes a properties array.

Is singleton DAO acceptable? -- Best Practices
All the DAO examples I've read have DaoFactory classes that always return a new DAO instance, and typically the action using it keeps a handle to it for that session. The DAOs that I've created have no state or instance variables, and get their connections from a synchronized pool (and always returning the connection within the same method call). So, since they are multi-threaded, it makes sense to me performance wise it is better for the factory to always return a singleton instance of the DAO. This single instance of the DAO is shared across all sessions in the JVM. (Note this is not the traditional usage of singleton where the singleton itself is responsible for returning the single instance through a static method). My question is, is this such a good idea? Am I missing or misunderstanding something crucial about the DAO Design Pattern? Mick. -- BR/ We all may have come on different ships, but were in the same boat now. Martin Luther King.

RE: Design question...
hi, If are getting some collection to the JSP page and just wish to display a subset of them without changing anything on BL layer, Use Pager Taglib and get away with it easily. But there is a downside to it as you may have 1000 records and you just want to show 10. So, 990 records are burden on network for no use at all. But you can avoid this also. Pager taglib provides you with one parameter offset that can be passed onto the controller layer and then to your Session EJB. Session EJB will trim the 1000 records collection obtained to 10 records based on that offset value. Now when you pass the DTO back, it will contain maximum 10 records. Reducing network load and you get only those records that you want in presentation layer.

Missing images style sheet in welcome file
Hi, In my web application (using struts), I have login.jsp as welcome file. I've defined the welcome file in web.xml as follows: welcome-file-list welcome-file/jsp/login.jsp/welcome-file /welcome-file-list And in login.jsp, I'm using relative path to load images and style sheet. My directory structure is as follows: ---web | |--css | |--jsp | |--images | |--WEB-INF login.jsp is located in /web/jsp folder. In login.jsp, I'm including style sheet as follows: link href=../css/style.css rel=stylesheet type=text/css ../css/style.css -- the style sheet is located in /web/css folder. Now, when I browse http://localhost:8080/myApp, login.jsp is displayed as welcome page, but the style sheet is not found. Same is the case with images on login.jsp. (this problem is occurring on Linux) But when I use http://localhost:8080/myApp/jsp/login.jsp, then it is displaying everything perfectly. And http://localhost:8080/myApp displays the login page correctly on Windows. Any idea what could be the problem? Sriram
Re: Issue in using struts-html-el tag
Hi Aattai,
Well, all the configurations you made in your jsp are fine.
in the html-el:text, you have mentioned that it should be populated to
the assign property of the bean. But how will the el tag know, the
name of the bean, this property belongs to ?.
better you specify the name of the bean also html-el:text styleClass=
smalltext name=***FormBean property=assigns
value=${***FormBean.assign}/
Hope this helps,

Re: How to dynamically decide the properties of the DynaValidator/DynaActionForm
The struts-validator configuration xml requires you to name the form
fields to be validated and the validation it depends on, at design time.
I am not sure about this, but it might be possible to define your
validation to do all possible validations on a form bean. I haven't
tried putting extra fields in a validation.xml that aren't present in
the struts-config form definition. Perhaps it's possible, perhaps it
will fail.
It won't be too difficult though to write your own validate routine, and
just drop the validator. I assume you are not so ambitious to want
javascript validation as well!

I don't really know the internal workings of the dynavalidator form

You would probably have to do the same formbean initialization in
the bean's reset method, otherwise the request parameters will
probably not get saved to it.
Once you get that far, then validation becomes an issue. At design
time you don't what the fields of a form will be - but do you know
how any particular type of field should be validated? If so, how do
you know? Is that in the design?

Re: How to dynamically decide the properties of the DynaValidator/DynaActionForm
sorry, I meant to say regarding validation, if you try defining 50 form
fields in a validation.xml, then you have to have 50 names. You would
also have to copy and paste the whole form definition for each form.
Sounds less and less like a good idea, if it even works.

RE: Disallow user to modify URL in browser address bar
Veeraswamy, Thanks for that. I have done the same. Instead of HTTP_REFERER, I have used 'referer'. When I was working with ASP, I have done this with HTTP_REFERER and I tried the same with JSP-Struts application also. But it didn't work. Then I printed all the headers and noticed that it should be 'referer' instead of 'HTTP_REFERRER' This is working now. But I am wondering if this a good practice or not because I have not seen this as a standard anywhere.

Re: How to dynamically decide the properties of the DynaValidator/DynaActionForm
You cant expect struts validator to do all the work, its nice and shows
you how to get started. But yes you'd have to use the validator libs
and get that running yourself. I wouldn't build a form around the
limitations of validator. I'll have to get the time to try this out and
iron out the wrinkles.
No populating the form in submit i don't think will work as the
dynaform need to the size of the property, before the page loads.
I'd approach the validator as a separate problem. You'll need to read
the commons validator stuff and work that out another day. Validator
can be layered on afterwards, and i'd suggest you'll have enough on
your hands getting something like this running.

Okay .. I've been thinking about this.
I think it might work something like this..

The arrayList will be a container for your beans with indexed

So in jsp we're thinking, or aiming for
logic:iterate id=bean name=myForm property=beans
bean:write name=bean property=key[%= index %] /
html:text name=bean property=value[%= index %] /
/logic:iterate
So we have a bean thats mapped backed, or something here's some
pseudo code.
public class MyBean {
private Map map;
public Object[] getKeys() {
return map.keySet().toArray();
}
public Object[] getValues() {
ArrayList list = new ArrayList();
Object[] keys = getKeys();
for(int i = 0;i keys.length;i++) {
String value = map.get(keys[i].toString());
list.add(value);
}
return list.toArray();
}
public String getKey(int i) {
return keys[i].toString(); }
public String getValue(int i) {
String key = getKey(i);
return map.get(key);
}
public void setKey(int i, String str) {
keys[i] = str;
}
public void setValue(int i , String str) {
map.put(getKey(i),str);
}
...
well you get the idea..
Am I tree barking, smoking crack or something but Its starting look
possible.. el should help move the scriptlets out, but using
indexed, mapped properties looks like it may do the job.. the bean
could have a double sided array it returns to keep the keys and
values in the correct order. The keys are after all the illusion
that the properties have names, when really they are associated via
index. When it comes time to write to a db or something the bean
could return a map and the key=value pairs should all be there
ready.

I don't really know the internal workings of the dynavalidator form
and how struts would populate the form bean with request
parameters. You would probably have to do the same formbean
initialization in the bean's reset method, otherwise the request
parameters will probably not get saved to it.
Once you get that far, then validation becomes an issue. At design
time you don't what the fields of a form will be - but do you know
how any particular type of field should be validated? If so, how
do you know? Is that in the design?

So what's you list 'concesiones' full off then? The browser thing looks

ArrayList concesiones = new ArrayList();
Concesion c = new Consesion();

all indexed properties in it. I need to display this data using
logic:iterate tag. does struts provide any functionality similar to this.
The data has to be displayed in html table format, by selecting any column
for sort, the other properties need to be ordered according to the sorted
column
my form bean:
public class IterateForm extends ActionForm {
private int intIndexed[] ={1,2,3,4,5};
private String strAry[] =
{ String 0, String 1, String 2, String 3, String 4 };
public String getStringIndexed(int index) { return (strAry[index]); }
public String[] getStringIndexed(){
return strAry;
}
public void setStringIndexed(int index, String value)
{ strAry[index] = value; }
public int getIntIndexed(int index) {
return (intIndexed[index]);
}
public int[] getIntIndexed() {
return intIndexed;
}
public void setIntIndexed(int index, int value){
intIndexed[index] = value;

RE: Is singleton DAO acceptable? -- Best Practices
Mick, The design pattern doesn't states how DAO's are to be implemented, but rather what problem they are supposed to solve. One reason why you might not want a DAO to be a singleton is if you instantiate one with an Connection. This might be done to avoid having to pass the Connection to each method. I think your implementation is appropriate. It makes sense performance wise and it is also intuitively more OO. Why create a new instance of an object if it does not maintain state? My .02, robert -Original Message- From: news [mailto:[EMAIL PROTECTED] Behalf Of Mick Wever Sent: Sunday, August 24, 2003 12:59 PM To: [EMAIL PROTECTED] Subject: Is singleton DAO acceptable? -- Best Practices All the DAO examples I've read have DaoFactory classes that always return a new DAO instance, and typically the action using it keeps a handle to it for that session. The DAOs that I've created have no state or instance variables, and get their connections from a synchronized pool (and always returning the connection within the same method call). So, since they are multi-threaded, it makes sense to me performance wise it is better for the factory to always return a singleton instance of the DAO. This single instance of the DAO is shared across all sessions in the JVM. (Note this is not the traditional usage of singleton where the singleton itself is responsible for returning the single instance through a static method). My question is, is this such a good idea? Am I missing or misunderstanding something crucial about the DAO Design Pattern? Mick. -- BR/ We all may have come on different ships, but were in the same boat now. Martin Luther King.

If you're storing the errors under the key dashboard, you need to extract

RE : Validator and Dispatch Actions
you have to use (Dyna)ValitatorActionForm instead of (Dyna)ValidatorForm. Then in your validation.xml file for each new rule you specify you have to replace the name of the form by the name of the action using the form. And the rule will be applied to the form only if it's called from the action you gave the name. In your case you have to specify 1 form, 3 actions and 3 rules. thomas -Original Message- From: manglu [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 26, 2003 1:33 AM To: [EMAIL PROTECTED] Subject: Validator and Dispatch Actions Hi, I want to use the Struts Validator to do validation.

multilingual app
hi all, I'm trying to build a multilingual application with struts. I have created 4 messages ressources named AppResources_fr.properties AppResources_uk.properties AppResources_de.properties AppResources.properties One file per country and the default(AppResources) for unknown user local. those file will be configured in the struts-config.xml file with a specific key for each. depending on user local, I would like to tell to the framework to load the corresponding Resource file. I have two questions about that : 1 : how could I tell to the framework to load resource file depending on the user local 2 : if I want to display values, could I use the bean write tag. 3 : for data comming from database, what is the best pratice to perfom the same thing. any suggestion would be greetly appreciated.

Re: RE : Validator and Dispatch Actions
This being the case, say you had a situation where your form had a few fields that would be disabled/not displayed if a user didnt have a certain access level. If you wanted 2 separate validation schemes for this form (one that has all fields being validated, one that has all fields except for the disabled/not shown fields being validated) then you would need 2 action classes (or 2 dispatch methods in the case below)? If the actions will be executing similar, if not identical code based on the fields submitted, this seems like an awful lot of rework just to get the validation accomplished.

Re: DynaForm Beans and Indexed Text fields.
it should work with just..
form-property name=pmiRanges type=java.util.ArrayList /
theForm.set(pmiRanges, (ArrayList) currentRates.getPmiRanges());
You dont need session.setAttribute.. and this can lead to you thinking
that's life's great when its not..
and then ...
ArrayList rateList = (ArrayList) theForm.get(pmiRanges);
rates.setPmiRanges((List) rateList);
I've been doing this okay using ArrayList so you could try that.I guess
the class cast exception make have been thrown when you tried seting
pmiRanges with an Object rather than list its stored as an object like
with so many things in java.

Re: ActionForm null after context restart?
Howdy ya'll, I posted this Friday but no one's biting so far... Has anyone had problems with session-scoped ActionForms being null after (de)Serialization (context restart).

As soon as I try to request either action that utilizes the ActionForm, I get problems.

One reason why you might not want a DAO to be a singleton is if you instantiate one with an Connection. This might be done to avoid having to pass the Connection to each method.

The DAOs that I've created have no state or instance variables, and get their connections from a synchronized pool (and always returning the connection within the same method call). So, since they are multi-threaded, it makes sense to me performance wise it is better for the factory to always return a singleton instance of the DAO. This single instance of the DAO is shared across all sessions in the JVM. (Note this is not the traditional usage of singleton where the singleton itself is responsible for returning the single instance through a static method). My question is, is this such a good idea?

[ANN] Model-driven Development for Struts/EJB
August 25, 2003 Alpharetta, GA - Metanology releases new Model-driven Development Environment (MDE) products Overview: MDE is a full featured, model-driven development environment that includes a UML modeler and MetaProgramTM editor that integrates with a Java IDE. MDE transforms a simple UML model of an application into the majority of the implementation by executing MetaPrograms. Applications are completed using traditional development techniques. MDE for EJB and MDE for J2EE enhance the company's existing MDE for Struts. MDE for EJB creates session beans, entity beans, message driven beans, business objects and value objects from simple UML models. MDE for J2EE enhances MDE for Struts and MDE for EJB by interfacing the Struts user interface to EJB services. Platform Independent Modeling Typical modeling techniques require a class for each element in the implementation resulting in complex models that are difficult to understand and maintain. MDE promotes modeling what the application does, not how it is built, making modeling fast, easy, and reusable across platforms. MetaPrograms A combination of Java and JSP-style syntax, MetaPrograms are easy to write, contain all the technical details of architecture, and create multiple files in the implementation from a single class in the model. MetaProgramming with MDE gives you complete control of how the model is turned into code. Rather than writing all the code by hand, MetaProgramming let's you write the code that writes the code.TM MDE Life Cycle Life cycle benefits are two fold. First, life cycle tools preserve your hand-written code from one generation to the next. Second, they replace existing MetaProgram generated code with updated MetaProgram code. Used to its fullest, MDE is ideal for iterative and incremental development methods, Agile and Extreme Programming. Learn more and download a free evaluation at www.metanology.com.

Design question
Hi,
We are developing a application which will have number of create screens, as follows :
Create Technology screen,
Create Project screen,
Create user screen.
etc
Each screen will have a asssociated formbean as follows.
TechnologyForm for Create Technology screen
ProjectForm for Create Project screen,
UserForm for Create user screen
etc.
Each form will have the object of underlying dataobject, and each form will have a
method getDataObject.
e.g.
Techonology form contains .
.
.
.
.
private TechDBO tech; # TechDBO is underlying dataobject.
.
.
.
.
TechDBO getDataObject(){
return this.tech;
}
.
.
.
.
execute method will have more or less same code as
.
.
.
dblayer.create(form.getDataObject());
.
.
.
.
So I am planning to club all the create in one action class and forward to appropriate
jsp as per some parameter by in formbean.
my struts-config.xml will be something like this.
action
path=/create
type=CreateAction
name= ???
input= ???
forward name=Tech path=successtech.jsp /
forward name=user path=successuser.jsp /
forward name=project path=successproject.jsp /
Now my questions are :
1 I am doing write something wrong.
2 Validation errors are to be send to called jsp. Like validation error for create
user has to be send to create user jsp, for that i need to dynamically change the
value of input in my action mapping, how to do this.
3 Since the form beans are different for each jsp can i dynamically change the
formbean of the actionmapping
4 can you suggest some alternate method so that i can not have to do copy past of my
code in execute method of action class.
TIA
Deepak.

Re: multilingual app
If you use *_EN.properties test.string = hello!! *_FR.properties test.string = allo!! rather than lower case will work out the box, no need to specify in struts-config just in web.xml as you perhaps have done already. The internationalization is built in. Try it out by changing your browser locale.. bean:message key=test.string / Tiles defs have similar functionality. I'll leave the question on the model to someone else..

Validator JavaScript and html:radio buttons
Hi all. I have two radio buttons on a page, one both named outcome one with the value of Accepted and one with the value of Rejected. In my validation.xml file, I say that outcome is required. The Javascript checking generated by the Validator framework doesn't give an error if neither on is selected, however the backend will, and produce an error I can see with the html:errors tag. How do I get the javascript to check the radio buttons to make sure one is selected? __ Do you Yahoo!? Yahoo!

RE: Validator JavaScript and html:radio buttons
The Javascript checking generated by the Validator framework doesn't give an error if neither on is selected, however the backend will, and produce an error I can see with the html:errors tag. IIRC, it's invalid HTML unless exactly one of the radio button options is selected. In your case I'd pre-select whichever value makes sense and expect the user to change it if they don't like that choice. No idea about the JavaScript though, sorry! -- Wendy Smoak Applications Systems Analyst, Sr. Arizona State University, PA, IRM

Cool! I receive email in plain text, so the Platform Independent, MetaPrograms, and Life Cycle weren't distinguished from the rest of their paragraphs, so it reads funny. It's probably better to use a separate line as a heading in the future, similar to the Overview, but without the colon.

MDE transforms a simple UML model of an application into the majority of the implementation by executing MetaPrograms. Applications are completed using traditional development techniques. MDE for EJB and MDE for J2EE enhance the company's existing MDE for Struts. MDE for EJB creates session beans, entity beans, message driven beans, business objects and value objects from simple UML models. MDE for J2EE enhances MDE for Struts and MDE for EJB by interfacing the Struts user interface to EJB services. Platform Independent Modeling Typical modeling techniques require a class for each element in the implementation resulting in complex models that are difficult to understand and maintain. MDE promotes modeling what the application does, not how it is built, making modeling fast, easy, and reusable across platforms. MetaPrograms A combination of Java and JSP-style syntax, MetaPrograms are easy to write, contain all the technical details of architecture, and create multiple files in the implementation from a single class in the model. MetaProgramming with MDE gives you complete control of how the model is turned into code. Rather than writing all the code by hand, MetaProgramming let's you write the code that writes the code.TM MDE Life Cycle Life cycle benefits are two fold. First, life cycle tools preserve your hand-written code from one generation to the next. Second, they replace existing MetaProgram generated code with updated MetaProgram code.

Re: validator returns blank page
Hi Thomas
Here what I would do.
struts-config.xml:
actionpath=/logon/action/logon
type=test.web.struts.action.logon.LogonAction
name=logonForm
scope=request-- !!!
validate=false -- !!!
input=/WEB-INF/jsp/logon/logon.jsp
forward name=success path=/index.jsp/
/action
LogonAction.java:
ActionErrors errors = new ActionErrors();
errors = form.validate(mapping, request);
// Report any errors we have discovered back to the original form
if (!errors.isEmpty())
{
saveErrors(request, errors);
return new ActionForward(mapping.getInput());
}
And be sure that your Class extends DynaValidatorForm.
Hope this helps

Probs migrating custom ActionMapping from 1.0.2 to 1.1
Ladies and gents, Having an issue with migrating our application over from 1.0.2 to 1.1. Specifically, we have a problem in the following line from our ActionServlet: ModuleConfig modCfg = RequestUtils.getModuleConfig(request, getServletContext()); SecureActionMapping secAMapping = (SecureActionMapping) modCfg.findActionConfig(path); The second line gives a ClassCastException whenever a request is made. The hierarchy for SecureActionMapping is: ActionConfig +- ActionMapping +- SecureActionConfig +- PackagingActionMapping +- SecureActionMapping Further, the mapping init-param in web.xml points to this SecureActionMapping class. The class type being returned by the findActionConfig(String) method is ActionConfig, although the servlet appears to be configuring itself properly during the initModuleConfig(String, String) method of ActionServlet. So my question is this: Is there a different mechanism for specifying the default ActionMapping class than doing so in web.xml?

Re: Probs migrating custom ActionMapping from 1.0.2 to 1.1
For 1.1, I believe you'd use: action-mappings type=pkg.SecureActionMapping action .../ ... /action-mappings The mapping init-parameter is deprecated in 1.1. You could also customize the actions on an individual basis with: action-mappings action className=pkg.SecureActionMapping .../ ... /action-mappings Quoting James Childers [EMAIL PROTECTED]: Ladies and gents, Having an issue with migrating our application over from 1.0.2 to 1.1.

Re: ActionForm null after context restart?

struts and flash
i saw a thread on using flash with struts from about a year ago, and i was wondering what the current state of affairs was. i was a good doobie and wrote my application in pretty strict MVC form, but now i'm looking at refactoring it to use a flash front-end (with dynamic communication back to the server), and it's looking like a complete mess. basically, i want my Model layer to remain as it is (java / jdbc / mysql), and the View layer to be flash - i'd prefer to leave the Controller as a struts application. is this possible, while still allowing the front-end to talk to the server dynamically? daniel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Tiles Definition problem
Bryce, To show a tile inside an independent, externally usable JSP, you're going in the wrong direction. I also suggested this broken path so let me help you get on the right path. These below 2 lines are all you need in your index.jsp to invoke your tile. I have included some explanations below on why the other methods didn't work. Your taglib URL might be different, so be sure to check your web.xml file. %@ taglib uri=/tags/struts-tiles prefix=tiles % tiles:insert definition=default.layout/ You were using a logic:redirect tag. I even wrote to you to take out the 'redirect=true' and use the forward. I didn't think it out clearly. A logic redirect tag forces the container to kick out a redirect which tells your browser to try the URL: http://localhost:8080/default.layout The problem is, that url isn't real. It is a tile and tiles cannot be accessed over the web that way. They can only be accessed within Struts or within pages in a way that is very different from the struts-logic tags. I was next going to suggest the more logical logic:forward tag, but the documents on Struts 1.1 note it cannot be used with tiles: Note: forwarding to Tiles definitions is not supported from this tag. You should forward to them from an Action subclass. From my perspective, you can either setup an action such as '/testtiles.do' to go to the tile: action path=/testtiles type=org.apache.struts.actions.ForwardAction parameter=default.layout/ Or force the JSP to import the tile definition and display it using a JSP made of two simple lines: %@ taglib uri=/tags/struts-tiles prefix=tiles % tiles:insert definition=default.layout/ I might use this method for my application's main homepage /index.jsp, just to remove the initial redirect that I might otherwise use (as it slows the user down a second or two as they get the HTTP redirect and ask for the new /index.do page). For everything else, I think I'll be consistent and use actions (*.do) for external access, not JSPs.

Re: RE : RE : Validator and Dispatch Actions
In this case, if I have one Save button on my page, and want either Action
A or Action B to get executed, is the preferred method to set the action
of the form dynamically in a function, something like:
fnSetAction()
{
myForm.action=actionA;
myForm.submit();
}
Or is there a different preferred way of accomplishing this?
Thanks

you don't need 2 action classes.
you may declare 2 actions in the struts-config.xml file using the same
class.
but you have to declare 2 formset tags in the validation.xml file,
setting up each form name with the action path instead of the form name.
in the first formset tag you define validation rules for all the fields
and in the second you do it only for a part of them.
using the first action will validate all the fields and using the second
will validate only a part of them.

This being the case, say you had a situation where your form
had a few
fields that would be disabled/not displayed if a user didnt
have a certain
access level.
If you wanted 2 separate validation schemes for this form
(one that has all
fields being validated, one that has all fields except for
the disabled/not
shown fields being validated) then you would need 2 action
classes (or 2
dispatch methods in the case below)? If the actions will be
executing
similar, if not identical code based on the fields submitted,
this seems
like an awful lot of rework just to get the validation accomplished.

you have to use (Dyna)ValitatorActionForm instead of
(Dyna)ValidatorForm. Then in your validation.xml file for
each new rule
you specify you have to replace the name of the form by the
name of the
action using the form. And the rule will be applied to the
form only if
it's called from the action you gave the name.
In your case you have to specify 1 form, 3 actions and 3 rules.

Hi,
I want to use the Struts Validator to do validation.
The Same action form is used for SEARCH, CREATE and EDIT.
The validation rules for each of them is different( from
the other
two)
How do i go about defining such a config in the validation config
file.
Appreciate any help.

html in ActionMessage resource keys?
Hi,
I am wondering if html tags, such as br, be used in the message
resource bundle keys? I want to have some formatting for an
ActionMessage, similar to what one gets using the ActionErrors and the
errors.prefix, errors.header and errors.footer keys (by default = BR,
UL, /UL respectively).
When I create a message key in my resource bundle, such as
messages.warning.general=Warning,the following problem occurred BR {0}
and use the following type of tag to display the message:
html:messages message =true property=warning id=msg
libean:write name=msg/
/html:messages
I get the following in the html source:
liWarning,the following problem occurred:lt;BRgt; access problem
What I want is the following:
liWarning,the following problem occurred:BR access problem

reloading page from array of checkbox
I'm creating checkboxes like this: html:checkbox property=abc value=xx/html:checkbox html:checkbox property=abc value=yy/html:checkbox html:checkbox property=abc value=zz/html:checkbox I define it in my form (DynaForm) like this: form-property name=abc type=java.lang.String[] / This submits to the server fine, all the checkboxes have their value set in the array. However, when reloading the page with the form in the session, the checkboxes don't get set. All my other controls get set from the values in the form, but struts doesn't understand the array of values to set the checkboxes. Is there some trick to doing this? Am I going to have to give each checkbox its own property to get it to set on page load? I know this would work, but I'd rather keep in array if possible.

The error messages says that stmt/rs already have been declared.
This is done in these lines in the beginning of the method
//Declare and initialize variables

Statement stmt = null;
ResultSet rs = null;
Change the later lines and remove the Statement and ResultSet words
respectively
and it should compile

All very simple. The problem is that, after the file is downloaded, the browser window is just left hanging there with the last contents displayed. I need a way to close that window. The best solution would be to display a confirmation page in the window after the download and then allow a user to click a button to close the window. Second best would be to just close the window. I tried returning an ActionForward, both a regular forward and a redirect, from my action and it seems that it is simply ignored. I tried setting onsubmit=window.close() on the form that starts the download, but then the download doesn't happen. I searched the archives, with no success. Any help is appreciated.

RE: Java Question
Since you have already Defined the conn and stmt you no need to defined
again .
public class OrgIdService implements Serializable {
//Declare and initialize variables
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
ArrayList facilList = new ArrayList();
Just remove Statement and ResultSet from line 56 and 57
Compile again it will work fine.
Eg :
stmt = conn.createStatement();
rs = stmt.executeQuery(SELECT

Bryce, You're welcome. -David -Original Message- From: Bryce Fischer [mailto:[EMAIL PROTECTED] Sent: Monday, August 25, 2003 3:55 PM To: Struts Users Mailing List Subject: Re: Tiles Definition problem David. Thank you very much. I knew I was missing something very simple. I had 2 books I had been referencing, Programming Jakarta Struts and Struts In Action. I guess I missed the forward thing in those docs.

RE: struts and flash
wish I knew ActionScript well enough to write all my pages in Flash. Anyway, I found this link online: http://www.smartwebby.com/Flash_and_ASP/Flash_sends_data.asp It tells you how to send a request to an ASP page. The basic should be the same. Worth a try:). -Original Message- From: Daniel Blumenthal [mailto:[EMAIL PROTECTED] Sent: August 25, 2003 1:02 PM To: Struts Users Mailing List Subject: struts and flash i saw a thread on using flash with struts from about a year ago, and i was wondering what the current state of affairs was. i was a good doobie and wrote my application in pretty strict MVC form, but now i'm looking at refactoring it to use a flash front-end (with dynamic communication back to the server), and it's looking like a complete mess. basically, i want my Model layer to remain as it is (java / jdbc / mysql), and the View layer to be flash - i'd prefer to leave the Controller as a struts application. is this possible, while still allowing the front-end to talk to the server dynamically? daniel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Html-el:hidden tag!?!?!
Why is it that the html-el:hidden tag has no styleId attribute? -- Tim Slattery [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Connector or Apache and Tomcat
Mohan, What are you looking to do? Write one Struts-based webapp (probably with modules) to merge and replace all of that on one IP? I'm developing the same way: 2 sites, different looks controlled with Tiles, both on one IP. The trouble is if you need SSL on multiple sites then they need their own IP's for their SSL certificates.
