Jazz Provisioning of hello world gives NPE in the browser
Hello,
I was following the example from https://jazz.net/wiki/bin/view/Main/UsingAppWizard to create a simple Hello World app. As I test it with embedded Jetty, it all works fine. However, when I try to build an update site and follow the Jazz provisioning instructions, https://jazz.net/wiki/bin/view/Main/ProvisionAppInJFS calling my application from web browser http://localhost:9080/myapp/hello results in: java.lang.NullPointerException com.ibm.team.repository.provision.internal.ProvisionService.installFeature(ProvisionService.java:330) com.ibm.team.repository.provision.internal.ProvisionService.installFeature(ProvisionService.java:356) com.ibm.team.repository.provision.internal.ProvisionService.installFromProfiles(ProvisionService.java:733) com.ibm.team.repository.provision.internal.ProvisionService.installFromProfiles(ProvisionService.java:702) com.ibm.team.repository.provision.internal.InstallServlet.service(InstallServlet.java:185) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) org.eclipse.equinox.http.servlet.internal.ServletRegistration.handleRequest(ServletRegistration.java:90) org.eclipse.equinox.http.servlet.internal.ProxyServlet.processAlias(ProxyServlet.java:111) org.eclipse.equinox.http.servlet.internal.ProxyServlet.service(ProxyServlet.java:59) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) org.eclipse.equinox.servletbridge.BridgeServlet.service(BridgeServlet.java:121) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) I am using Eclipse 3.4 with target platform pointed to: com.ibm.team.jfs.sdk.feature-I20090420-1525 and with com.ibm.team.jfs.sdk.ide.feature-I20090420-1525 installed. Have I missed something? Any advice would be appreciated. Regards, Blazej |

Hello, could anyone drop me a line with any piece of advice?
I would like to make it work, but I am stuck on this NullPointerException. Regards, Blazej |
Let me clarify:
- Which version of Foundation Server do you use? - Do you get the NPE when you access http://localhost:9080/myapp/install? - Did you build the update site before export it? "Right click on the site.xml file and go to the PDE Tools menu option. Select Build Site". - Does the exported update site contain features/com.ibm.team.jfs.sdk.runtime.feature_0.7.0..jar ? |

Hello wakao,
thank for asking questions to clarify. When looking for answers I found the root cause of the problem! The problem was due to the fact, that I used as a target platform just the JSF SDK's 45 plug-ins (which was set up automatically as I used 3.5RC1 for developping). And should also include the dependant plug-ins from Eclipse installation. When I did that the project compiled and was deployed into Tomcat. Now I have to make it run on the server, because the project created with the wizard is not working out of the box, am I right? Accessing http://localhost:9080/myapp/install work fine but accessing http://localhost:9080/myapp/examples/hello does result in a message that: There is no REST service handler registered for the path Thanks and regards, Blazej |

How about accessing http://localhost:9080/myapp/hello ?

How about accessing http://localhost:9080/myapp/hello ? I am givem this error. Should I develop a REST service hanler myself? I thought the app wizard is doing it out of the box? HTTP Status 403 - There is no REST service handler registered for the path "/hello" Thanks in advance, regards Blazej |

App wizard generates a template REST service which runs without any modification.
Can you run your application in your Eclipse environment just after generating the code by App Wizard? 1. Run -> Run Configurations... 2. Select OSGi framework 3. Select "New" from Context Menu 4. Select all bundles 5. Run Then try to access http://localhost:9080// |
