+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+
+   9. Accepting Warranty or Additional Liability. While redistributing

+
+<div class="row">
+    <div class="large-12 columns">
+        This example shows how to use Servlet REST to define REST endpoints in Camel routes using the Rest DSL
+
+        <br/>
+
+        This example is implemented in both the Java and XML DSLs. By default the Java DSL is in use.
+        You can change this in the src/main/webapps/WEB-INF/web.xml file
+
+        <br/>
+        For Java DSL the routes are defined in Java code, in the <tt>org.apache.camel.example.rest.UserRouteBuilder</tt>
+        class.
+        And for XML DSL the routes are define in XML code, in the <tt>src/main/resources/camel-config-xml.xml</tt> file.
+
+        <p/>
+        There is a <i>user</i> REST service that supports the following operations
+        <ul>
+            <li>GET /user/{id} - to view a user with the given id</li>
+            <li>GET /user/final - to view all users</li>
+            <li>PUT /user - to update/create an user</li>
+        </ul>
+
+        The view operations are HTTP GET, and update is using HTTP PUT.
+
+        From a web browser you can access the first two services using the following links
+
+        <ul>
+            <li><a href="rest/user/123">user/123</a> - to view the user with id 123</li>
+            <li><a href="rest/user/findAll">user/findAll</a> - to list all users</li>
+        </ul>
+
+        From the command shell you can use curl to access the service as shown below:
+<pre>
+    curl -X GET -H "Accept: application/json" http://localhost:8080/camel-example-servlet-rest-tomcat/rest/user/123
+    curl -X GET -H "Accept: application/json" http://localhost:8080/camel-example-servlet-rest-tomcat/rest/user/findAll
+    curl -X PUT -d "{ \"id\": 666, \"name\": \"The devil\"}" -H "Accept: application/json" http://localhost:8080/camel-example-servlet-rest-tomcat/rest/user
+</pre>
+
+        Notice when trying to get user with id 789 then there is a built-in delay of 0.5-2 seconds, to simulate some
+        slowness in the service.
+
+        <p/>
+        This example offers an API browser using Swagger which is accessible from the following link
+        <ul>
+            <li><a href="api-docs">api-docs</a> - list all CamelContexts in the JVM that may have REST services</li>
+            <li><a href="api-docs/myCamel">api-docs/myCamel</a> - myCamel - overview of the apis from the REST services</li>
+            <li><a href="api-docs/myCamel/user">api-docs/myCamel/user</a> - myCamel - api of the user REST service</li>
+        </ul>
+
+        <p/>
+        To use the swagger ui, follow this link. Replace the URL value with this one to access the REST local resources http://localhost:8080/camel-example-servlet-rest-tomcat/api-docs/myCamel
+        <ul>
+            <li><a href="index.html">swagger</a> - swagger ui page</li>
+        </ul>
+
+        <p/>
+        If you hit any problems please let us know on the
+        <a href="http://camel.apache.org/discussion-forums.html">Camel Forums</a>
+        <br/>
+        <br/>
+        Please help us make Apache Camel better - we appreciate any feedback you may
+        have. Enjoy!
+        <br/>
+        <br/>
+        The Camel riders!
