Which target platform shall I use?
Hi,
I'm working on developping a server component. When I create a plug-in project, which target platform shall I select? Eclipse or an OSGi framework? I thought it may be OSGi framework - Equinox. But I found in the JazzTalk tutorial, the default value "Eclipse 3.3" is selected, and that component works well. Is there any difference between these two options? BTW, the JazzHelloWorld doesn't work in 0.6M2. Is it out of date? Thanks! |

Hi, I just generated two plug-ins with the new plug-in wizards. For one I selected Eclipse 3.3 and for the other I selected OSGI Equinox. Then I compared the generated files (MANIFEST.MF, build.properties, .project, ..classpath) and they all look the same to me. I'm not enough of an Eclipse expert to know if there should be some subtle difference. It seems like you should be fine with either path. One related topic is the Execution Environment (which can be set from the Overview tab of the manifest editor). I notice that the primary jazz component plug-ins specify J2SE-1.5 for this, so you may want to specify that for your plug-ins.
Do you mean HelloJazz (https://jazz.net/learn/LearnItem.jsp?href=content/docs/hello-jazz/index.html) or a different tutorial? Can you describe the problem you are seeing? I reviewed and fixed-up HelloJazz (and others) for M2, but perhaps I missed something. |

Chris, thanks!
Do you mean HelloJazz In fact, I mean the tutorial of "Writing a Jazz Web Hello World Page" (https://jazz.net/learn/LearnItem.jsp?href=content/docs/web-ui-programming/web-ui-hello-world.html). After I complete all steps of the instructions, the Hello World page is always on the loading status.

In fact, I mean the tutorial of "Writing a Jazz Web Hello World Ok I created defect 30139 for this. I think that several of the web UI docs need a review post-M2. Subscribe to the defect if you want to follow progress. |

Chris,
I've tried the HelloJazz you mentioned in M2, it seems workable in function, but I find some error message in the eclipse console.

Chris, I have seen this exception stack before. When I saw it I was using "remote mode" (see: https://jazz.net/wiki/bin/view/Main/JazzServerRunAndDebug if you're not familiar with that term) and I had messed up my launch configuration by using "Add Required Bundles" in the launch dialog. When I see NoClassDefFoundError my first guess is that something is wrong with the launch configuration. Either something is missing (like the plug-in that contains the class that didn't load) or there is some kind of initialization order problem. I know that HelloJazz describes a local mode setup. Are you doing it that way or are you using remote mode when you see this? Chris |

Chris,
actually, I got the error message when I followed the tutorial of HelloJazz using local mode. In fact, in my workspace, there are other plgu-ins from other Jazz tutorials. When I remove all these plug-ins, the HelloJazz works without previous error messages. There may be some loading error for those plug-ins. Thanks a lot! |
