Hi dhaval.

Read official documentation from http://www.springframework.org/documentation
and take a look to the samples that comes with spring-framework. http://sourceforge.net/project/showfiles.php?group_id=73357&package_id=173644&release_id=452461

I began reading Spring in Action book.

Hello Krishna.



Seems like you are trying to configure your i18n with a ViewResolver and it is impossible. ViewResolver interface has been created to achieve other issues.

To achieve the i18n for your application you need to configure the messageSource interface.

For example:



messages and errors are a properties files, messages_it_IT.properties for example.

Then, if you want a way to change the language of your web application you just have to add a localeInterceptor like this:



If you want to change the language you need something like <a href="login.html?language=it_IT">



The locale will be kept in a cookie.

Note: replace &CookieLocaleResolver for CookieLocaleResolver. I can't post without "&" symbol.

Regards, Jordi.

Hello Ben!

Override referenceData method. With that you could display your test outlines in your form page.

SimpleFormController API
Hi!

I have a Map<String,List>. To get the value from a Map I know that I have to do ${map["key"}].

My problem is that I have to do that inside a forEach where each key is a variable.

Example:

<c:forEach var="i" items="${parents}">
${child[${i.id}]]}
</c:forEach>

It doesn't work. Any advices?

Thanks in advance

Hello,

I'm a newbie and I have a question about Tomcat and instances.

I read some time ago that when a user do a request, the container give an instance of the web aplication to the user, translate jsp code to servlet code, and show to the user the html, then each user of the aplication will have an instance of each class (that the jsp code needs) in every request.

My question is there is a way to have a single instance (for example Users.class) shared by application users? Then if a user change something
of that class, all users see that change.

Thanks in advance.

Hi!

With JDOM I can read a XML document and delete some nodes and finally write this document into file.xml.

With XPath, I can read a XML and then apply an expresion that get some nodes that I can delete. My problem is how to write that document (without deleted nodes) into file.xml

Any examples?

Thanks in advance
Hi!

You can get a number to know if a user exists or not, you can do that:

public boolean userExists() {
string sql ="SELECT count(*) FROM users WHERE login=loginparameter AND password=passparameter;
int x = jt.queryForInt(sql); //jt = jbdcTemplate
if(x == 1) { out = true; } else { out = false; }
return out;
}


in your controller you can have a validator like this


on submit {
if(!userExists) {
err.reject("Error");
return showForm(request,response,err);
}
}

Hi!

I suppose that you have a form to edit your object.

Try it, imagine that you want to edit a book)





The command class of your form displayed to edit the book have to has that property:



And then, in your form, in name field (for example)



Regards,
First of all search and read the theory about MVC architecture, when you finish I would recommend you that take a look to some web framework that use MVC architecture as Spring or Struts.

Hi!

I'm using Netbeans 5.0 with java 1.5 and tomcat 5.5.17.

When I do generics in non web project, netbeans compile it perfeclty, however if I do generics in web project netbeans get me an error message "generics are not suported in source -1.4"

If I have JDK 1.5 in my java plataform manager why netbeans get me that error in web projects?

I found in project.properties inside nbproject folder a line with:
javac.source = 1.4
javac.target=1.4

If I chanche 1.4 to 1.5 all works fine. Why netbeans put 1.4 in javac.target and source by default if I have jdk1.5 version?

Thanks in advance

Take a look into java graphs

I've used Graphviz, I converted xml file to *.dot file and then get the graph with exec command.

Copy the path of your package that contains your javabean and the <jsp:useBean tag that you use in your jsp file.

Seems like you are putting a package that doesn't exists
