eclipse repository p2 build tycho maven plugin pde rcp update-site

    The packaging type eclipse-repository was originally introduced for building products that can be updated with p2 (cf. TYCHO-188). This requires the following build results: a p2 repository which contains the product IU, and a zip file with the installed product. (Although this is technically no longer needed since the Update Manager was replaced by p2, zip files are still the primary way to distribute Eclipse/RCP installations.) For ease of implementation, this was done in the same packaging type eclipse-repository. In the meantime, eclipse-repository has gained in capabilities (in particular through TYCHO-491), making it difficult for users to choose the right packaging types. This page lays out the mid-term plan of how we want to build products, update site categories, and p2 repositories in Tycho. It also contains a few details how the transition todays (0.11.0) packaging types (eclipse-repository, eclipse-application, eclipse-update-site) to the new types eclipse-repository and eclipse-product.

Saga EDA pattern - distributed transaction coordinator manager - SOA patterns - Reservations | SOA Zone - 0 views

    "Unfortunately, in a distributed world, SOA or otherwise, it is rarely a good idea to use atomic short lived transactions (see the Cross-Service Transactions anti-pattern in chapter 10 for more details). Indeed, the fact that cross service transactions are discourages is one of the main reasons we would to consider using the Saga pattern in the first place. One of the obvious shortcomings of Sagas is that you cannot perform rollbacks. The two conditions mentioned above, locking and isolation do not hold anymore so you cannot provide the needed guarantee. Still, since interactions, and especially long running ones, can fail or be canceled Sagas offer the notion of Compensations. Compensations are cool; we can't have rollbacks so instead we will reverse the interaction's operation and have a pseudo rollback. If we added one hundred (dollars/units/whatnot) during the original activity we'll just subtract the same 100 in the compensation. Easy, right?"

  • Oracle provided the EC with a Java SE 7 specification request and license that are self-contradictory, severely restrict distribution of independent implementations of the spec, and most importantly, prohibit the distribution of independent open source implementations of the spec.  Oracle has refused to answer any reasonable and responsible questions from the EC regarding these problems.
  • In the phrase "fail to uphold their responsibilities under the JSPA", we are referring to Oracle's refusal to provide the ASF's Harmony project with a TCK license for Java SE that complies with Oracle's obligations under the JSPA as well as public promises made to the Java community by officers of Sun Microsystems (recently acquired by Oracle.)
  • it should be noted that the majority of the EC members, including Oracle, have publicly stated that restrictions on distribution such as those found in the Java SE 7 license have no place in the JCP - and two distinguished individual members of the EC, Doug Lea and Tim Peierls, both have resigned in protest over the same issue.
  • ...9 more annotations...
  • By approving Java SE 7, the EC has failed on both counts : the members of the EC refused to stand up for the rights of implementers, and by accepting Oracle's TCK license terms for Java SE 7, they let the integrity of the JCP's licensing structure be broken.
  • The Apache Software Foundation concludes that that JCP is not an open specification process
  • and finally, the EC is unwilling or unable to assert the basic power of their role in the JCP governance process
  • In short, the EC and the Java Community Process are neither.
  • To that end, our representative has informed the JCP's Program Management Office of our resignation, effective immediately.  As such, the ASF is removing all official representatives from any and all JSRs. In addition, we will refuse any renewal of our JCP membership and, of course, our EC position.
  • Okay ! Java's privatized now... What now ?
  • Thank god I moved off Java in time. Suddenly Oracle is the new Death Star, replacing Microsoft.
  • This is a sad, sad day in the Java community. I hoped that Oracle would back-peddle and realize the folly of their ways. Now Java will be to Oracle what .NET is to Microsoft and it will be the death of Java as we know it.
  • Posibly in few years we'll see Apache as a new Sun for "Java", followed by Eclipse, Google, etc... I hope this is a great movement done by Apache for the community. We'll see... The objetive of Oracle are Enterprises that cannot move from Java because of hight investments, it will earn a lot of money from them. Oracle ignores the community because is not going to pay for (expensive, as all the rest of Oracle products) licenses... We'll se...

    The Apache Software Foundation has resigned its seat on the Java SE/EE Executive Committee. Apache has served on the EC for the past 10 years, winning the JCP "Member of the Year" award 4 times, and recently was ratified for another term with support from 95% of the voting community. Further, the project communities of the ASF, home to Apache Tomcat, Ant, Xerces, Geronimo, Velocity and nearly a 100 mainstay java components have implemented countless JSRs and serve on and contribute to many of the JCPs technical expert groups. We'd like to provide some explanation to the community as to why we're taking this significant step.
