It's not the servlet that manages the connections, but the data source, that
acts also as a connection pool. For more information, see:
http://commons.apache.org/dbcp/
This data source is created by the servlet.
The reason why it is deprecated is that it mixes the Controller and the
Model layers of the MVC model.

Notice that JNDI support depends on the container. Even Tomcat 4.1.xsupports it.

Hi,

I have downloaded what is discribed as the latest "best available" release
of STRUTS 2.0.11.1 (http://struts.apache.org/downloads.html)
I am following the tutorial "Using tags" where the example uses a URL tag
with the "var" attribute.
    <s:url var="url" action="Welcome">

However this crashes since the TLD in the struts2-core-2.0.11.1.jar does
not define the "var" attribute.
It is however discribed in the documentation.

Is this a bug ?
If so when will it be fixed ?
What can I use as a workaround ?
I see in some of the example applications "id" is used, and in the
documentation it states:
    id    Deprecated. Use 'var' instead

Is it safe to use id instead ? What are the differences between the two ?

Regards
Ian
