Re: [S2] apply i18n on java entity from DB
Few more thoughts on this matter: I haven't explicitly said that the solution I've proposed is far from standard i18n functionality, it was my best choice for the given example. If the "Product" described in the first message is pure fiction and you have the ability to change the data model you can get rid of the multiple names from the "Product" entity, put a "unique_name", use it to point to resource in your bundle with some static prefix like "product.name.". The actual names of the items you'll store like standard message resources. You can even use database message resources if you are not fan of the properties files. This way you'll get rid of the custom internationalization algorithms but it's definitely not the easiest way to go. The good thing about this solution is that you can go with it as far as adding new language for product names becomes a matter of simple configuration.

Re: [S2] apply i18n on java entity from DB
Hi Steven,
I don't know what's the best practice but I'll give you my quick thoughts.
It seems you have to implement some sort of logic (choosing the right name).
The main question is where is the best place to put this kind of logic?
IMO this kind of problems are solved using the "decorator pattern".
In the given example I'd choose to create "decorator" class for the
Product class
public class LocaleAwareProduct extends Product {
private Locale locale;
private String displayName;
private LocaleAwareProduct() {
// hide the default constructor
}
private LocaleAwareProduct(Produt aProduct, Locale aLocale) {
this.locale = aLocale;
if ( "en".equalsIgnoreCase(aLocale.getLanguage()) ) {
this.displayName = aProduct.englissh_name;
} else {
if ( "fr".equalsIgnoreCase(aLocale.getLanguage()) ) {
this.displayName = aProduct.french_name;
}
{
}
}
Wrapping "products" into "locale aware products" will enable you to
fetch the display name of a product without implementing the logic
into the "view component".
NOTE: the Java code has been typed in text editor and have never been
compiled so it might be buggy.
Regards,
Dimitar Vlasev

Re: Handling probel.
I'm surprised how many people are asking questions the way nobody can help them Which version of struts are you using? If I use your .do pattern as a sign i might roll the dice and guess looking the guts of the sacrificed animal you are using Struts 1.x, aren't you? you should have struts dispatcher servlet configured in your web.xml with some servlet mapping action org.apache.struts.action.ActionServlet config /WEB-INF/struts-config.xml 1 action /do/* If the poor animal died without being able to help me, and you are using Struts 2.x then you'll have a filter mapping struts2 org.apache.struts2.dispatcher.FilterDispatcher struts2 /* These configurations are used from Tomcat to determine which module will take care / work onto / your request. Look for any configuration that might interfere with Struts dispatcher configuration. There might be some security constraints that prevent action execution. This is what I can think of. You'll need to investigate it. Good luck. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: setting a text field
Hi, have you ever read something about struts forms before asking questions here? Don't feel offended but this is a base functionality and I'm pretty sure you will not receive much help about issues like this. And you'll need to provide at least the version of Struts you're using. I guess you're using Struts 1.x Setting the value of the form field in the action that precedes the forward to the jsp will do what you need if all your configurations are OK. The form field is property of a struts form configured for your action. If this does not ring any bells for you you'll really need to read something for the version of Struts you're using. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Dojo datetimepicker problem
Sure I succeeded wrapping the String to Date conversion outside of the action class with custom type conversion class. I guess I expected that when uses java.util.Date property when rendering the HTML, I will get the new value in the same property after submitting the form which holds the Since I don't think the automated String to Date conversion stated here http://struts.apache.org/2.0.14/docs/type-conversion.html will do well for real application I didn't even try to go this way. Having the ability to use static content as attribute value made the solution with custom type conversion class good enough and I didn't bother further with this.

You'll have to set the default value to your action property:

Re: Dojo datetimepicker problem
Few findings:
http://struts.apache.org/2.0.14/docs/type-conversion.html
at section "Built in Type Conversion Support" documentation says:
XWork will automatically handle the most common type conversion for
you. This includes support for converting to and from Strings for each
of the following:
.
-> dates - uses the SHORT format for the Locale associated with the
current request
.
But I haven't tried yet to utilize this feature.
This is what worked for me:
What I've done was to create custom type conversion class
---
public class ShortDateConverter extends StrutsTypeConverter {
public final static String pattern = "dd.MM.";
private final static SimpleDateFormat format = new
SimpleDateFormat(pattern);
public Object convertFromString(Map context, String[] values, Class
toClass) {
Date result = null;
if (values != null && values.length > 0) {
try {
result = format.parse(values[0]);
} catch (ParseException e) {
throw new TypeConversionException("Error
converting date from '" +
values[0] + "', pattern: '" + pattern + "'");
}
}
return result;
}
public String convertToString(Map context, Object o) {
return null;
}
}
and applied it to the setter method within my action class:
(it worked well both using annotation and
-conversion.properties file)
-
@TypeConversion (type=ConversionType.CLASS,
converter="test.ShortDateConverter")
public void setADate(Date date) {
...
Though it would be even elegant enough solution if I was able to refer
to the static pattern String in the .jsp like that
But I got exception:
According to TLD or attribute directive in tag file, attribute
displayFormat does not accept any expressions
I hope these findings will help someone else.

Re: Dojo datetimepicker problem
Thank you Timothy, I've suspected something like that. Of course anyone can read Date from String but the question was is this behavior a bug or a feature. Musachy: has attribute "displayFormat" but not "format". Of course it's not user friendly format thus I can't really use it in application, however I run a test with the format defined in RFC3339 and I hit the same rock again (the automated conversion didn't happen). here is what's being generated from the - .

Dojo datetimepicker problem
Hi all,
I'm using Struts 2.0.14.
I'm experiencing the following problem:
I tried to use datetimepicker in sample application and it worked fine
except that the java.util.Date property does not retrieve the new
value selected in the interface.
I don't have more time today to check this out and will continue
trying to fix it tomorrow.
What's more weird if i have getter for a String property with the same
name I'll get the text that's in the edit box rendered from
Here are some snippets from my test application:
struts.xml
---
.
tiles_test
the JSP
---
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
User Details changed
Submit Date
the Action (implements RequestAware)
--
private Date aDate = new Date()
public String fetchDate() {
OgnlValueStack valueStack = (OgnlValueStack)
this.request.get("struts.valueStack");
log.info("- this.aDate: " + this.aDate.toString());
log.info("- vs: aDate: "
+valueStack.findString("aDate"));
log.info("- vs: dojo.aDate: "
+valueStack.findString("dojo.aDate"));
return Action.SUCCESS;
}
public Date getADate() {
return aDate;
}
public void setADate(Date date) {
log.info(" Date set to: " + date.toString());
aDate = date;
}
public void setADate(String s) {
log.info(" this one is called :" + s);
}
console output
--
17:37:24,644 INFO [Test] this one is called :12/3/08
17:37:24,644 INFO [Test] - this.aDate: Tue Dec 02 17:37:24 EET 2008
17:37:24,644 INFO [Test] - vs: aDate: 12/2/08
17:37:24,644 INFO [Test] - vs: dojo.aDate: null
as you can see setADate(Date date) never get's called.
I've checked the request made from the browser (using FF with FireBug)
and the post parameters were fine "aDate" and "dojo.aDate" where both
set to the correct value 12/3/08
I appreciate greatly your help.
Regards.

How to place struts2-core.jar outside web-app.war?
Hi, I'm having problem to configure web application enclosed in .ear module. I'm using Struts 2.0.12 and JBoss 4.2.3 running on java 1.6. The application is in .war module, which is placed inside .ear module.
