Troubles with REST extensions on Jetty
I am trying to develop a REST extension following the article:
https://jazz.net/library/LearnItem.jsp?href=content/docs/web-ui-programming/web-ui-todo-rest.html
But I got some troubles for deploying the examples on the Jetty Server:
java.lang.IllegalArgumentException: The com.example.jazz.todo.common bundle's plugin.xml file contains a <service> element that has a missing 'uri' attribute value.
What uri should be used?
Other messages:
[ERROR] 2015-03-25 11:11:17.550 - FrameworkManager: An error event has occurred involving the bundle "org.eclipse.emf.edit_2.5.0.v200906151043 [54]". org.osgi.framework.BundleException: The bundle "org.eclipse.emf.edit_2.5.0.v200906151043 [54]" could not be resolved. Reason: Another singleton version selected: org.eclipse.emf.edit_2.6.0.v20100914-1218 |

Hello... the referenced article is from 2007 and the plug-in API has changed. If you have access to the jazz wiki, an article that shows how to create a REST service is here: https://jazz.net/wiki/bin/view/Main/JAFTutorialStepREST
This describes a REST service called as:
The plug-in format to create the service is...
<plugin>
<extension point="com.ibm.team.repository.common.components">
<component id="com.ibm.team.jaf.sdk.samples.hellojaf" name="Hello JAF">
<service kind="MODELLED_REST" name="Hello JAF Rest Service"
uri="com.ibm.team.jaf.sdk.samples.hellojaf.IHelloService"
version="1"/>
</component>
</extension>
<extension point="com.ibm.team.repository.service.serviceProvider">
<serviceProvider componentId="com.ibm.team.jaf.sdk.samples.hellojaf"
implementationClass="com.ibm.team.jaf.sdk.samples.hellojaf.HelloService">
<provides>
<providedService interface="com.ibm.team.jaf.sdk.samples.hellojaf.IHelloService" />
</provides>
</serviceProvider>
</extension>
<extension point="com.ibm.team.jfs.app.appMode">
<appMode
delegatingAuthentication="true"
transitioningToJAF="false">
</appMode>
</extension>
<extension point="com.ibm.team.jazz.foundation.server.products">
<product
id="com.ibm.team.jaf.sdk.samples.hellojaf"
name="Hello JAF"
requiredJtsVersions="[4.0.0,6.1.0)"
type="APPLICATION"
version="4.0.0.0">
</product>
</extension>
</plugin>
The appmode and products extensions are not needed but I kept them here to keep the sample file complete.
The java file is:
package com.ibm.team.jaf.sdk.samples.hellojaf;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.ibm.team.jfs.app.http.util.HttpConstants;
import com.ibm.team.repository.service.TeamRawService;
public class HelloService extends TeamRawService implements IHelloService {
@Override
public void perform_GET(String uri, HttpServletRequest request, HttpServletResponse response) throws IOException {
response.setCharacterEncoding(HttpConstants.DEFAULT_ENCODING);
response.setContentType(HttpConstants.CT_TEXT_PLAIN);
PrintWriter writer = response.getWriter();
writer.write("Hello world");
}
}
