Web projects (Servlet level 2.2 to Servlet level 2.4)

Artifacts of a Web deployment descriptor are migrated by the J2EE Migration Wizard when a J2EE 1.2 Web project is migrated to the J2EE 1.4 specification level.

The following Web application artifacts are migrated:

Authentication constraints

J2EE 1.4 includes a Description object that has two attributes: language and value. This Description object did not exist in J2EE 1.2; the description was an attribute on the Authentication Constraint. So, when the artifacts of a Web deployment descriptor are migrated to J2EE 1.4, the value of the Description object is taken from the description attribute of the Authentication constraint.

Security constraints

Similarly, in J2EE 1.2 the description was an attribute on Security Constraint . In J2EE 1.4 there is new Description object with the attributes language and value. So, the value of the Description object is taken from the description attribute of the Security Constraint.

Web application

The description string attribute of the ContextParam object in the J2EE 1.2 specification level has been moved to a Description object in ParamValue in J2EE 1.4.

The TagLib object in J2EE 1.2 has been moved to the JSPConfig object in J2EE 1.4. The JSPConfig objects belonged to the Web root object in 1.2.
