Check the documentation for the tag
http://struts.apache.org/2.0.14/docs/select.html
I was referring to the attribute 'name', which indicates the name used to
get the select value from the Action, and also to send the value back to the
server. It should be something like this

Well, the NPE is due to the fact that you are setting declaring dt_oid as an
Integer(which can be null) but in the method listdomain is an int. The JVM

Struts does not know that yo want to should map that domainType to your
bean. It wil try to map the parameters received from the request to the
action. So for each parameter it founds in the request received from the

No its not present in the action class. That snippet was taken from the bean
class, that im using to set the values. Pardon my ignorance , but should i
set it in the action class too? (because i dont use it in the action class
directly ).
The bean class is just a set of getters and setters that im
humm, that snippet is not in the Action you gave before. Can you provide the
current version of the Action ?

The snippet doesn't actually help, and can't you just include small

The headerKey is a number, what are the ones filled by the tag? What

occur under some type conversion conditions.)

In the action there is no setDomainType. Is it suppoused to be a parameter
received from the user? where is it used?

The ParameterInterceptor is in the default stack of Struts2. If you are
using the default stack, it should work automatically. If not, you need to
add it to your interceptor stack.
http://struts.apache.org/2.0.6/struts2-core/
Are you aware there is Struts 2 documentation?

Well, ParametersInterceptor should take care of that. Do you have devMode
enable? check the logs, you should find there if it is been used, and if it
is working.

Just to comment that Struts2 will populate the parameter from the request if
you aure using the corresponding interceptor, or the default stack.
