Re: [dali-dev] [wtp-dev] (no subject)

Hi,

I found EclipseLink SDK only at marketplace. It is not available on the update site. However, the target platform (Eclipse SDK) does not have Marketplace menu option. So I can install it only to the host platform, but not to the target.

Then I tried to download JDT SDK, so I can at least look around that API. I could not find it neither on the marketplace nor on the update site.

I found only this http://archive.eclipse.org/eclipse/downloads/drops/R-3.4.1-200809111700/index.php . I downloaded and copied feature and plugin dirs into my eclipse. Sources are still not available. Of course, it does not check compatibility and dependencies, so it would be more surprise if it would work.

Am I missing something fundamental? I did some eclipse plugins few years ago (they used JDT and EMF) and do not remember it to be that hard. If I recall right, everything used to be available in the update site.

Hi,

thank you for taking time to answer, that wiki is what I was looking for.

I downloaded all packages except Eclipse SDK from build 3.1.1. Eclipse SDK was not linked, so I took it from 3.3.0. I hope it is not a problem.

I'm using Eclipse for RCP, Helios release (host platform).

Most projects compile, thirteen have problem:
  org.eclipse.jpt.common.ui
  org.eclipse.jpt.common.ui.tests
  org.eclipse.jpt.dbws.eclipselink.ui
  org.eclipse.jpt.jaxb.eclipselink.ui
  org.eclipse.jpt.jaxb.ui
  org.eclipse.jpt.jpa.core
  org.eclipse.jpt.jpa.db.ui
  org.eclipse.jpt.jpa.eclipselink.core
  org.eclipse.jpt.jpa.eclipselink.ui
  org.eclipse.jpt.jpa.ui
  org.eclipse.jpt.jpadiagrameditor.ui
  org.eclipse.jpt.jpadiagrameditor.ui.tests
  org.eclipse.wst.common.modulecore.ui

The most common problem is missing class in package org.eclipse.persistence . It should be part of eclipselink (I think), but I do not know where to get it.

I tried:
1.) randomly search through cvs repository,
2.) download eclipselink OSGI bundle zip from http://www.eclipse.org/eclipselink/downloads/index.php and copy it to the target platform. It did not help.
3.) update my eclipse to install 'EclipseLink Target Components ' into my eclipse, the update was impossible:
  An error occurred while collecting items to be installed
  session context was:(profile="" phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action="">   No repository found containing: osgi.bundle,commonj.sdo,2.1.1.v200905221342
  No repository found containing: osgi.bundle,javax.activation,1.1.0.v201005080500
 ...

Some projects require graphity, but my default target platform does not have that. According to dev page, Graphity should be in different target platform then the rest. I guess that I have to switch between them depending on what I'm doing. Is that right?

Hi,

I recently started to use Dali sub-project and found it neat and useful. Thanks for the good work.

I would like to see the source code of JPA related part and maybe contribute something.  Finding out how to start was more difficult than I expected. Hopefully, someone can answer my questions.
It sounds like we have some more work to do to ease the getting started process.   Luckily there are many here who can help you get started.  This is jumping ahead, but there are many on the dali-dev list who would be able to help.  There isn't a lot of traffic on that list, but it is well monitored.

Theoretical questions:
* Is there an interest for outside contributions?
Absolutely.  It can be tough to get started with Dali contributions giving the underlying complexity of the technology itself, but we have had many successful contributions over the years.

* Do you have some documents I should read before starting?
Yes, I would recommend starting here - http://wiki.eclipse.org/Dali_Developer_Documentation.  This should answer many of the practical questions below.

* Is this the right mailing list? I found also dali-dev mailing list, but it has only weekly status reports in it. Plus, Dali web page has a link on this one.
dali-dev would be the best mailing list to use.  It will have the specific Dali community you are looking for.  It looks like when the web page was refactored we lost our specific mailing list link.  I'll look into that.


Practical questions:
* Is there a document that describes what should I download and how to build that?
http://wiki.eclipse.org/Dali_Developer_Documentation There is one set of unneeded projects that are currently only serving as a shell for maintenance builds.   In the "jpa" component, you will only need plugins that begin with org.eclipse.jpt.jpa.  All of the others are unnecessary for head development.  As to whether you need all the remaining plugins probably depends on what you are interested in doing.  Generally speaking,  committers on the project have all of the "plugins" plugins and "tests" plugins in their workspace.  A separate Dali workspace is probably a good idea. : )

* The above repo depends on missing bundles, where do I get them? Do I really need them all?
All of these external dependencies will be a part of your target platform when developing Dali.  When you build a target platform all of these bundles will be included, so there is nothing specific you will need to do to get them.  And yes, Dali has many external dependencies, most of which are Eclipse and some of which that are not.  See http://wiki.eclipse.org/Dali_Developer_Documentation for information on how to build your target platform.
