To get a init parameter from same package, I can make it:
in web.xml
<context-param>
<param-name>PARAM</param-name>
<param-value>1</param-value>
</context-param>
and my java class:
FacesContext.getCurrentInstance().getExternalContext().getInitParameter( "PARAM" );
It's ok for same package. But, if I want access via my class java, a web.xml from another package? How I should make it?
