RE: Creating an indexed property of DynaActionForms
Use the lazyValidatorActionForm, which allows you to keep things request scope when
using arrays.
http://www.niallp.pwp.blueyonder.co.uk/
form-bean name=SampleMain
type=org.apache.struts.validator.DynaValidatorForm
form-property name=subForm1 type=java.util.ArrayList/
form-property name=subForm2 type=java.util.ArrayList/
/form-bean
Unfortunately I haven't tried this, but am pretty sure it works.

Subject: Creating an indexed property of DynaActionForms
I'm trying to figure out how to define and use a DynaActionForm which
has an indexed property that is another DynaActionForm. I'm using
struts 1.1. Here is something like what I mean:
First my sample struts-config.xml
--
form-bean name=SubForm
type=org.apache.struts.validator.DynaValidatorForm
form-property name=property1
type=java.lang.String/
form-property name=property2
type=java.lang.String/
/form-bean
form-bean name=SampleMain
type=org.apache.struts.validator.DynaValidatorForm
form-property name=subForm1 type=SubForm[]/
form-property name=subForm2 type=SubForm[]/
/form-bean
And the JSP:
--
table
c:forEach var=subForm1 items=${SampleMain.map.subForm1}
varStatus=status
tr
tdhtml:text
property=subForm1[${status.index}].property1 size=5 /
tdhtml:text
property=subForm1[${status.index}].property2 size=5 /
/tr
/c:forEach
/table
Unfortunately this doesn't work. If I try making the subtypes SubForm[]
like above, I get a NullPointer exception when I try to start the
server, when struts tries to create the DynaForm classes.
If I make the property type Object[], I can successfully populate the
form, but when I try to save it, I get an ArrayOutOfBounds error when
struts tries to create the initial DynaForms (Obviously because it has
no idea what type of form to create, I think).
How do I make this work?
Also, once I start implementing validation on this form, is it going to
be possible to use struts validation to validate the subitems?
Thanks,
Nathan

RE: Problem with html:checkbox
And what happens when you are using a DispatchAction and a session scoped form? If you are in a wizard use case, where you go forwards and backwards in a screen sequence using Dispatch action and session scoped form, if in the first screen you set the checkbox on and then you want to go back and unset it, you should check in the request.getParameter() if it is null to set it to false (according to Rajani's reply), because the ActionForm getter for the boolean property won't be populated.

RE: Jbuilder 9 Changing Stuts 1.0 to 1.1
I use JBuilder 8 with Struts 1.1 and no real problems (okay, you need to
make it forget 1.0 exists or it will try to put back the wrong dtd's in
your WEB-INF directory when you startup).
Look at the JBuilder defintion for the Struts Library under Configure
Libraries, you want to make a 1.1. version just like it, this includes
telling where the struts tld's are.
For JBuilder 8, I needed to tell it it was a custom framework, and NOT a
Struts framework because it would make assumptions that were 1.0 related
(i.e. a template tld, but no tiles tld, etc).
Declare your project to use this library. Copy the TLD's into the
WEB-INF directory like JB wants, and it should work fine. Did for me
anyway.

Yes it - is. I use Jbuilder 9 and struts 1.1
You need to manually configure it:
- Add 2 new libraries through Tools/Configure Libraries - call one
Struts 1.1 and the other Struts 1.1 JSTL
- For Struts 1.1 JSTL
- add classes %strutsdir%/contrib/struts-el/lib/jstl.jar and
%strutsdir%/contrib/struts-el/lib/standard.jar
- Framework- choose JSTL and define all libraries eg core
(EL) prefix
c, core (RT) prefix c_rt
- For Struts 1.1
- add classes commons-beanutils.jar, commons-collections.jar,
commons-digester.jar, commons-fileupload.jar, commons-lang.jar,
commons-validator.jar, jakarta-oro.jar, struts.jar,
struts-el.jar all
from %strutsdir%/contrib

RE: Problem with html:checkbox
What I had to do is to read the parameter out of the request. If the parameter is there, the value is 'true' and I call the setter to set the value to 'true'. If the parameter does not exist (the request.getParameter(...) returns null) then I call the setter and set the value to 'false'. On wizard type forms, I have a method which holds the values which were originally used to populate the form. For instance I read an row for the the database, my business delegate hands me a value object. This value object I store in the form bean. Should the user select and I use can use the to 'reset' the form to the original values.

Has anyone come across this before? - 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]
Action - nothing
I was wondering if there's any chance to create an action that do some processing and then return to the same page it was called. Thanks, Julio
RE: Action - nothing
Just create an action. The first time the action is called have it do:
return (mapping.findForward(display));
In the jsp code, when you specify the form tag do:
html:form action=/myAction?action=process
It will then go back to the original form with a parameter added:
String action = request.getParameter(action);
If (action != null action.equals(process)){
//Do Stuff
return (mapping.findForward(display));
}

Subject: Creating an indexed property of DynaActionForms
I'm trying to figure out how to define and use a DynaActionForm which
has an indexed property that is another DynaActionForm. I'm using
struts 1.1. Here is something like what I mean:
First my sample struts-config.xml
--
form-bean name=SubForm
type=org.apache.struts.validator.DynaValidatorForm
form-property name=property1
type=java.lang.String/
form-property name=property2
type=java.lang.String/
/form-bean
form-bean name=SampleMain
type=org.apache.struts.validator.DynaValidatorForm
form-property name=subForm1 type=SubForm[]/
form-property name=subForm2 type=SubForm[]/
/form-bean
And the JSP:
--
table
c:forEach var=subForm1 items=${SampleMain.map.subForm1}
varStatus=status
tr
tdhtml:text
property=subForm1[${status.index}].property1 size=5 /
tdhtml:text
property=subForm1[${status.index}].property2 size=5 /
/tr
/c:forEach
/table
Unfortunately this doesn't work. If I try making the subtypes SubForm[]
like above, I get a NullPointer exception when I try to start the
server, when struts tries to create the DynaForm classes.
If I make the property type Object[], I can successfully populate the
form, but when I try to save it, I get an ArrayOutOfBounds error when
struts tries to create the initial DynaForms (Obviously because it has
no idea what type of form to create, I think).
How do I make this work?
Also, once I start implementing validation on this form, is it going to
be possible to use struts validation to validate the subitems?
Thanks,
Nathan

Re: iterate through a HashMap of Integer[]'s
When you iterate through a map you are iterating through the Set of
Map.Entry values. The Map.Entry encapsulate a key-value pair.
Map.Entry has a key property and a value property. In your case, the
value itself is an Integer[]. Try the following:
logic:iterate id=mapEntry name=myBean property=myHashMap
logic:iterate id=intValue name=mapEntry property=value
bean:write name=intValue/
/logic:iterate

RE: Creating an indexed property of DynaActionForms
I don't think using the lazy beans is a bad approach and if you look at the code,
there is very little of it.
I got half way to implementing the approach, but the piece I was building was shut
down so I don't know how effective it is.

Use the lazyValidatorActionForm, which allows you to keep things request
scope when using arrays.

Subject: Creating an indexed property of DynaActionForms
I'm trying to figure out how to define and use a DynaActionForm which
has an indexed property that is another DynaActionForm. I'm using
struts 1.1. Here is something like what I mean:
First my sample struts-config.xml
--
form-bean name=SubForm
type=org.apache.struts.validator.DynaValidatorForm
form-property name=property1
type=java.lang.String/
form-property name=property2
type=java.lang.String/
/form-bean
form-bean name=SampleMain
type=org.apache.struts.validator.DynaValidatorForm
form-property name=subForm1 type=SubForm[]/
form-property name=subForm2 type=SubForm[]/
/form-bean
And the JSP:
--
table
c:forEach var=subForm1 items=${SampleMain.map.subForm1}
varStatus=status
tr
tdhtml:text
property=subForm1[${status.index}].property1 size=5 /
tdhtml:text
property=subForm1[${status.index}].property2 size=5 /
/tr
/c:forEach
/table
Unfortunately this doesn't work. If I try making the subtypes SubForm[]
like above, I get a NullPointer exception when I try to start the
server, when struts tries to create the DynaForm classes.
If I make the property type Object[], I can successfully populate the
form, but when I try to save it, I get an ArrayOutOfBounds error when
struts tries to create the initial DynaForms (Obviously because it has
no idea what type of form to create, I think).
How do I make this work?
Also, once I start implementing validation on this form, is it going to
be possible to use struts validation to validate the subitems?
Thanks,
Nathan

Re: Creating an indexed property of DynaActionForms
I don't understand why you need ActionForms embedded in your main
ActionForm - don't these sub forms just need to be some sort of DynaBeans
rather than ActionForm?
If you want to use the Lazy versions, then just make it your main
ActionForm:
form-bean name=SampleMain dynamic=true
type=lib.framework.util.LazyValidatorForm/
Then in your jsp
html:text property=subForm1[${status.index}].property1 size=5 /
html:text property=subForm1[${status.index}].property2 size=5 /
Should populate an ArrayList of LazyDynaBeans containing property1 and
property2

When you iterate through a map you are iterating through the Set of
Map.Entry values. The Map.Entry encapsulate a key-value pair.
Map.Entry has a key property and a value property. In your case, the
value itself is an Integer[]. Try the following:
logic:iterate id=mapEntry name=myBean property=myHashMap
logic:iterate id=intValue name=mapEntry property=value
bean:write name=intValue/
/logic:iterate

RE: Creating an indexed property of DynaActionForms
Lemme give an example, Lets say I have a form for Cars. The main form
allows them to put in the details of the Car (make, model, year, etc).
Then there is a subform to put in car parts. When you fill out the car
part form, it automatically adds that car part to the list of car parts
on the main form. You can then go back to the main form later, and
check off the parts of the car you have, and when you hit save on the
main form, it automatically saves the obtained status for each car part.
Basically a Main form with a dynamically generated list of items as part
of the form.
It is MUCH easier to save these records to the database if everything is
represented as DynaForms.

Re: logic:iterate over a collection of non-simple objects, how to fill them after submit
If your form is session scoped then the collection of beans will exist when your form is submitted back. For request scope, which I presume you are using, then you will need to generate your collection of beans. Theres been quite a bit of discussion on this list about how to do this - with a number of people using a LizyList class from Commons collections. http://cvs.apache.org/viewcvs.cgi/jakarta-commons/collections/src/java/org/apache/commons/collections/list/LazyList.java Also the LazyValidatorForm I wrote caters for this - take a look at the get(String name, int index) method in LazyValidatorForm for an example of what you need to do http://www.niallp.pwp.blueyonder.co.uk Niall - Original Message - From: Lachdanan [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, April 19, 2004 4:52 PM Subject: logic:iterate over a collection of non-simple objects, how to fill them after submit Hello, I have the following problem: I use a collection of objects of type AClass which have another collection as an attribute (%=anAttribute[+index.intValue()+]%). logic:iterate id=ABean type=de.abc.test.AClass name=AForm property=aCollection indexId=index TR TD html:select name=ABean property='%=anAttribute[+index.intValue()+]%' size=1 html:options name=AForm property=anIDList labelProperty=aNameList/ /html:select /TD /TR /logic:iterate The direction Form -- JSP works well.

Subject: Re: Validation with 2 masks?
Theres nothing in the standard mask validation that ships with struts
that
allows you to do this, but it would be pretty straight forward to write
and
configure your own validator to do this. Set up a static mehtod somewhere
that does pretty much what the FieldChecks.validateMask() method does,
except modify the variable name to something like mask2
public static boolean validateMask(Object bean,
ValidatorAction va, Field field,
ActionMessages errors,
HttpServletRequest request) {
String mask = field.getVarValue(mask2);
String value = null;
if (isString(bean)) {
value = (String) bean;
} else {
value = ValidatorUtils.getValueAsString(bean,
field.getProperty());
}
try {
if (!GenericValidator.isBlankOrNull(value)
!GenericValidator.matchRegexp(value, mask)) {
errors.add(
field.getKey(),
Resources.getActionMessage(request, va, field));
return false;
} else {
return true;
}
} catch (Exception e) {
log.error(e.getMessage(), e);
}
return true;
}
Then change the validation-rules.xml to add the second mask validator
validator name=mask2
classname=myPackage.MyFieldChecks
method=validateMask
methodParams=java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
javax.servlet.http.HttpServletRequest
depends=
msg=errors.mask2/
Then in your validation.xml, use both the standard mask and your mask2
validator:
form name=
field property=... depends=mask, mask
var
var-namemask/var-namevar-value^...$/var-value
/var
var
var-namemask2/var-namevar-value^...$/var-value

I'm writing the Actions separately, they are not Dyna-anything. I

Where I'm running into trouble is when I want to embed one dynabean

I don't understand why you need ActionForms embedded in your main
ActionForm - don't these sub forms just need to be some sort of
DynaBeans
rather than ActionForm?
If you want to use the Lazy versions, then just make it your main
ActionForm:
form-bean name=SampleMain dynamic=true
type=lib.framework.util.LazyValidatorForm/
Then in your jsp
html:text property=subForm1[${status.index}].property1 size=5 /
html:text property=subForm1[${status.index}].property2 size=5 /
Should populate an ArrayList of LazyDynaBeans containing property1 and
property2

Re: Non-Form Based Mapped Properties
I created a simple class with the map and setValue(Object key, Object value) as well as getValue(Object key). Then tested the class by putting an instance of the class into session scope on a page, retrieving the object on the same page, and trying to access the properties via the mapped properties value(keyName). I made sure the object was obtained via the logic tag, but the mapped property does not work for me. Any ideas? If not, I will put the whole thing into this exchange. Thanks.

Re: Non-Form Based Mapped Properties
Haven't done this but either your class needs to be a Map implementation or you need getter/setter for your Map public void setMyMap(Map myMap) public Map getMyMap() The problem with using the html tags and not having your Map as a property of the ActionForm is that when the form is submitted, Struts is going to try to populate these properties in the form.

RE: flaky error: Error - tag.getAsString : component context is not defined
Niall, thanks for your response.
It would appear that this is the result of the user having javascript
disabled on their browser. Also, once we established that the users were
not actually submitting their forms, but were getting the error as soon as
they clicked on the link, it made it much easier to narrow down the problem.
This was the link:
a href=# onclick=showhide('contactForm'); return(false);strongAdd
Contact Form/strong/a/td
The onclick is being ignored, and the a href=#... Was getting called
which was BAD. It's the same result as if I did a right-click on the link
and selected 'open in new browser'.
So.. Not a struts issue at all.
Cheers,
Janice

Then there is a subform to put in car parts. When you fill out the car
part form, it automatically adds that car part to the list of car parts

check off the parts of the car you have, and when you hit save on the

Re: what could cause this Class Cast exception
Well you need to get the original ResultSet out of the wrapper - I don't use
dbcp, but looking at the source code it looks like getInnermostDelegate()
does that.
http://cvs.apache.org/viewcvs.cgi/jakarta-commons/dbcp/src/java/org/apache/commons/dbcp/
The thing is, do you need to cast it to an OracleResultSet at all, can't you

RE: Getting the form bean on a page for use in a core tag
Bill,
Thanks for your help here. We actually ended up working down a different
path for this particular issue but I am now using this technique in
other code.
One thing we did to make the core tag code more generic was to store a
reference to the form bean in the request attributes under a short,
constant value ('formBean'). This way our el can look like
${formBean.map.txtFullLegalName}, much like the way the html tags pick
up the form bean by default. We were able to do this (setting the form
bean) consistently because we are running thru a little process type
action which is subclassed for each process.

Re: Getting the form bean on a page for use in a core tag
Struts already does this, it stores the form under the name you specified in
your action mapping. So if you have:
action path=/myActionPath name=myFom ...
Then struts stores the form under myForm in whatever scope you specify
(request or session).

RE: Getting the form bean on a page for use in a core tag
Niall,
Sorry if I was unclear, I understand that the form is placed in the
request as the form name, but what we were doing was putting it under a
constant key, so regardless of what you actually called the form in your
action element it would always be available in the request under a
constant key. I believe struts already does this also, but it uses a
rather long string, from memory 'org.apache.struts.taglib.html.BEAN',
but I don't believe that this would play nicely with EL expressions and
its too long to be convenient.

Can't figure how exactly what went wrong except for one or two things. Like the example shows for the property file : hibernate.dialect net.sf.hibernate.dialect.MySQLDialect hibernate.connection.driver_class org.gjt.mm.mysql.Driver hibernate.connection.driver_class com.mysql.jdbc.Driver hibernate.connection.url jdbc:mysql:///test hibernate.connection.username testuser See something wrong at line 4! Of course I did not see this at first!!! Should be hibernate.connection.url jdbc:mysql://localhost/test As far as it goes for the jdbc driver, I use mysql-connector-java-3.0.9 and no problem there. So that is something to know I guess. The Hibernate.properties file is in WEB-INF/classes. Also I am not familiar with Ant. But when using Eclipse like I do, I guess it is the best way to compile all classes with Eclipse i.e. it compiles automatically. But then this here : 12. Create directory |/com/edhand/example1| underneath |$TOMCAT/webapps/example1/WEB-INF/src/java|. Causes a problem. Because all packages are com.edhand, and Eclipse compile in java.com.edhand... Since then I also another example known as span. No success so far. And I haven't look at it for some days now...

Perhaps the first option is similar to GoF's command pattern. Thanks a lot in advance.

I couldn't get my properties file to work with spaces, I had to use equals signs: hibernate.dialect=net.sf.hibernate.dialect.MySQLDialect hibernate.connection.username=X hibernate.connection.password=Y hibernate.connection.url=jdbc:mysql://localhost:3306/test hibernate.connection.driver_class=com.mysql.jdbc.Driver As for your Eclipse problem, if you are using Eclipse v2.1.X (I'm on 2.1.3), try this: go to the Java perspective, right clicking on the project name, choose properties, select Java Build Path, and edit the Source folders on build path entry so $TOMCAT/webapps/example1/WEB-INF/src becomes $TOMCAT/webapps/example1/WEB-INF/src/java and make sure the Default Output Folder lists $TOMCAT/webapps/example1/WEB-INF/classes. That should class compilation so java files under WEB-INF/src/java compile WEB-INF/classes instead of showing up under WEB-INF/classes/java. I.E. WEB-INF/src/java/com/edhand/whatever.java shows up now (as you described below) compiled as WEB-INF/classes/java/com/edhand/whatever.java when this change would make it compile properly as WEB-INF/classes/com/edhand/whatever.java Regards, David -Original Message- From: Mario St-Gelais [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 21, 2004 10:14 PM To: Struts Users Mailing List Subject: Re: Struts and Hibernate David Friedman wrote: Mario, Where is your hibernate.properties file? in WEB-INF/classes or somewhere else?

RE: basic
RE: basic problem in java
I had trouble in a windows platform (Windows XP home) using directory names
that don't follow the old 8 letter (or less) prefix and 3 letter extention
in my ms-dos/command.com CLASSPATH variable. Using dir /x will show the
old dos-style directory or file name. I found that using those names worked
in my classpath so I could run Tomcat (or plain old Java programs) from the
command line. So, instead of using c:\jdk1.4.2, the dir/x might show it
as C:\JDK14~1.1 which works for me in the classpath while C:\jdk1.4.2
won't work so it won't find stock libraries like java.io.* or anything else
you'd expect.

Subject RE: basic problem in java
that probably won't compile either
import java.io.*;
class test
{
public static void main(String[] args)
{
System.out .println(My Apologies To all); }
}
you were missing ; after the import ant String [] as a paramter to main
was
declared wrong.
