Hi everybody
Today is my exam.I have found a line below in new specs of servlet.Please anybody explain me this as soon as possible.I am unable to understand it.

5. Support Alternative HTTP Methods with Authorization Constraints
The previous Servlet 2.4 schema restricted HTTP methods to GET, POST, PUT, DELETE, HEAD, OPTIONS, and TRACE. The schema http-methodType was changed from:



<xsd:complexType name="http-methodType">

...

<xsd:simpleContent>

<xsd:restriction base="j2ee:string">

<xsd:enumeration value="GET"/>

<xsd:enumeration value="POST"/>

<xsd:enumeration value="PUT"/>

<xsd:enumeration value="DELETE"/>

<xsd:enumeration value="HEAD"/>

<xsd:enumeration value="OPTIONS"/>

<xsd:enumeration value="TRACE"/>

</xsd:restriction>

</xsd:simpleContent>

</xsd:complexType>



To the following:



<xsd:simpleType name="http-methodType">

<xsd:annotation>

<xsd ocumentation>

A HTTP method type as defined in HTTP 1.1 section 2.2.

</xsd ocumentation>

</xsd:annotation>



<xsd:restriction base="xsd:token">

<xsd attern value="[\p{L}-[\p{Cc}\p{Z}]]+"/>

</xsd:restriction>

</xsd:simpleType>



The http-method elements now need to be a token as described in HTTP 1.1 specification section 2.2.[/QUOTE]

Don't panic, but you're looking at the wrong spec. You should be looking at Servlets 2.4, not 2.5.
