why does everybody use c:out tag ........???

[cujigar1]

<spring:bind path="command.password">

<input type="text" name="<c:out value="${status.expression}"/>"
value="<c:out value="${status.value}"/>"/>

</spring:bind>


when they can directly and easily use EL


<spring:bind path="command.emailAddress">
<input type="text" name="${status.expression}/>"
value="${status.value}"/>
</spring:bind>


note: i m referring to unnecessary usage of c:out tag

i just want to know that does using c:out has any advantage because all the examples in this world use it.

Anyone feel free to correct me on this one, but I believe that the second version only works if you are using a container that supports the Servlet API 2.4 therfore only people using the "latest and greatest" containers can take advantage of this format.

That is correct. In fact, it's not enough to be inside a Servlet 2.4 container. Your webapp must declare itself as 2.4, via it's doctype in the web.xml.

thanks for replying. now i know.

I also seem to remember we had trouble with <c:out> when it came to internationlization, and that <spring:message> was better.

Yes, c:out does not perform i18n. You can also use the fmt:message tag to perform translations. The fmt tag also has other formatting tags, for numbers and dates, to help with i18n.

Isn't the c:out also useful for getting a cross-side-scripting safe html encoded output?

The main reason to use c:out is that it escapes the given value according the xml rules.
Take a look at http://www.oreillynet.com/cs/user/view/cs_msg/32734 för example.
