LIMITED LICENSE GRANTS
1. License for Evaluation Purposes. Sun hereby grants you a fully-paid, non-exclusive, non-transferable, worldwide, limited license (without
the right to sublicense), under Sun's applicable intellectual property rights to view, download, use and reproduce the Specification only for the
purpose of internal evaluation. This includes (i) developing applications intended to run on an implementation of the Specification, provided
that such applications do not themselves implement any portion(s) of the Specification, and (ii) discussing the Specification with any third
party; and (iii) excerpting brief portions of the Specification in oral or written communications which discuss the Specification provided that
such excerpts do not in the aggregate constitute a significant portion of the Specification.
2. License for the Distribution of Compliant Implementations. Sun also grants you a perpetual, non-exclusive, non-transferable, worldwide,
fully paid-up, royalty free, limited license (without the right to sublicense) under any applicable copyrights or, subject to the provisions of
subsection 4 below, patent rights it may have covering the Specification to create and/or distribute an Independent Implementation of the
Specification that: (a) fully implements the Specification including all its required interfaces and functionality; (b) does not modify, subset,
superset or otherwise extend the Licensor Name Space, or include any public or protected packages, classes, Java interfaces, fields or methods
within the Licensor Name Space other than those required/authorized by the Specification or Specifications being implemented; and (c) passes
the Technology Compatibility Kit (including satisfying the requirements of the applicable TCK Users Guide) for such Specification ("Compliant
Implementation"). In addition, the foregoing license is expressly conditioned on your not acting outside its scope. No license is granted
hereunder for any other purpose (including, for example, modifying the Specification, other than to the extent of your fair use rights, or
distributing the Specification to third parties). Also, no right, title, or interest in or to any trademarks, service marks, or trade names of Sun or
Sun's licensors is granted hereunder. Java, and Java-related logos, marks and names are trademarks or registered trademarks of Sun
Microsystems, Inc. in the U.S. and other countries.
3. Pass-through Conditions. You need not include limitations (a)-(c) from the previous paragraph or any other particular "pass through"
requirements in any license You grant concerning the use of your Independent Implementation or products derived from it. However, except
with respect to Independent Implementations (and products derived from them) that satisfy limitations (a)-(c) from the previous paragraph,
You may neither: (a) grant or otherwise pass through to your licensees any licenses under Sun's applicable intellectual property rights; nor (b)
authorize your licensees to make any claims concerning their implementation's compliance with the Specification in question.
4. Reciprocity Concerning Patent Licenses.
a. With respect to any patent claims covered by the license granted under subparagraph 2 above that would be infringed by all technically
feasible implementations of the Specification, such license is conditioned upon your offering on fair, reasonable and non-discriminatory terms,
to any party seeking it from You, a perpetual, non-exclusive, non-transferable, worldwide license under Your patent rights which are or would
be infringed by all technically feasible implementations of the Specification to develop, distribute and use a Compliant Implementation.
b With respect to any patent claims owned by Sun and covered by the license granted under subparagraph 2, whether or not their infringement
can be avoided in a technically feasible manner when implementing the Specification, such license shall terminate with respect to such claims if
You initiate a claim against Sun that it has, in the course of performing its responsibilities as the Specification Lead, induced any other entity to
infringe Your patent rights.
c Also with respect to any patent claims owned by Sun and covered by the license granted under subparagraph 2 above, where the
infringement of such claims can be avoided in a technically feasible manner when implementing the Specification such license, with respect to
such claims, shall terminate if You initiate a claim against Sun that its making, having made, using, offering to sell, selling or importing a
Compliant Implementation infringes Your patent rights.
5. Definitions. For the purposes of this Agreement: "Independent Implementation" shall mean an implementation of the Specification that
neither derives from any of Sun's source code or binary code materials nor, except with an appropriate and separate license from Sun, includes
any of Sun's source code or binary code materials; "Licensor Name Space" shall mean the public class or interface declarations whose names
begin with "java", "javax", "com.sun" or their equivalents in any subsequent naming convention adopted by Sun through the Java Community
Process, or any recognized successors or replacements thereof; and "Technology Compatibility Kit" or "TCK" shall mean the test suite and
accompanying TCK User's Guide provided by Sun which corresponds to the Specification and that was available either (i) from Sun 120 days
before the first release of Your Independent Implementation that allows its use for commercial purposes, or (ii) more recently than 120 days
from such release but against which You elect to test Your implementation of the Specification.
This Agreement will terminate immediately without notice from Sun if you breach the Agreement or act outside the scope of the licenses
granted above.

Preface
This document is the Java™ Servlet Specification, version 3.0. The standard for the
Java Servlet API is described herein.
Additional Sources
The specification is intended to be a complete and clear explanation of Java Servlets,
but if questions remain, the following sources may be consulted:
■ A reference implementation (RI) has been made available which provides a
behavioral benchmark for this specification. Where the specification leaves
implementation of a particular feature open to interpretation, implementors may
use the reference implementation as a model of how to carry out the intention of
the specification.
■ A compatibility test suite (CTS) has been provided for assessing whether
implementations meet the compatibility requirements of the Java Servlet API
standard. The test results have normative value for resolving questions about
whether an implementation is standard.
■ If further clarification is required, the working group for the Java Servlet API
under the Java Community Process should be consulted, and is the final arbiter of
such issues.
Comments and feedback are welcome, and will be used to improve future versions.
Who Should Read This Specification
The intended audience for this specification includes the following groups:
