When the apache beam will be released?
Will it has feature to connect with oracle RDBMS to do ETL in its first release?
Apache Beam has had two incubating releases so far, with the third currently underway. We release the source code to dist.apache.org and binary jars to Maven Central Repository.
We don't release an all-inclusive bundled jar. Instead, we recommend using a tool like Maven (mvn), or m2e plugin in Eclipse, or native support in IntelliJ to make all dependencies automatically managed for you.
The third release should include the JdbcIO API, which presumably should work well with Oracle RDBMS.

I am following hello world application of Amazon Web Services Simple Workflow Service. According to description #Activities annotation should have been able to generate two classes GreeterActivitiesClient and GreeterActivitiesClientImpl. But these classes has not been generated.
I have Enable annotation processing in project properties. I am using Eclipse Mars with Jdk 1.8. I have also installed AWS toolkit for eclipse, aspectj.
Can someone see where the problem is?
Some versions of Eclipse, (notably Mars and Neon), may fail to fetch the latest artifacts due to a bug in old versions of the Oomph plugin. To work around this issue:
Make sure that you’re using https://aws.amazon.com/eclipse/site.xml as the AWS Toolkit for Eclipse update site.
Delete the ~/.eclipse/org.eclipse.oomph.p2/cache/ directory to remove cached content.
Install the latest version of Oomph (Eclipse Installer).

What do I need to do to use Apache Ignite in an Eclipse project?
I don't want to use Maven; I have Apache Luna; and I just want to use the in-memory data grid.
There are no steps specific with Apache Ignite. You will have to determine the whole set of required JARs including transitive dependencies and manually add them to your project. I would strongly recommend to use Maven or other dependency management tool. What is the reason for not using it?
I was previously using hadoop 1.2.1 in one of my netbeans project. I did this by including the various jar files in the 1.2.1 distribution I downloaded from hadoop's website.
I was wondering, is a similar approach with hadoop 2.2.0 possible? Namely, can I just include a bunch of jar files in my netbeans project and plug into hadoop that way?
Thanks in advance!
You can - There are more jars in the 2.x distributions of hadoop but the same principle should work.
On a side note, you may also want to look into using Maven for dependency management that will manage the list of included jars in Netbeans for you.
I'm running Eclipse Juno 4.2 (upgraded from Indigo 3.7), with the Spring Tool Suite tools installed. A while ago I had installed Spring Roo 1.2.2.RELEASE, and configured the Roo plugin to point to the 1.2.2.RELEASE runtime.
I would now like to upgrade to Spring 1.2.4.RELEASE, but cannot find the runtime anywhere. I've looked on the Spring site, but cannot seem to find a download link to it anywhere.
So a few questions:
1) Is the runtime still required as a separate download and do I still need to configure Eclipse to point to it separately?
2) Where can I download the runtime from?
3) Why do I need the separate runtime? Why is STS/Eclipse not smart enough to use the Roo artifact that is included in my maven project?
I still don't why I need the separate runtime to configure Eclipse, however, I did finally find a download link for the latest ROO packages: http://docs.spring.io/downloads/nightly/release-download.php?project=ROO
I've been beating my head against a wall for about 6 months now and have not found a concise way of understanding the mechanism for developing an eclipse plugin with third-party resources.
We are attempting to develop an Eclipse ODA to ride on top of in-house Spring-based code that accesses a REST based info set.
In broad strokes - this is what I feel that we need to be able to do:
Augment our maven artifacts with Eclipse bundle information using tycho or a the felix bundle plugin.
Set up a plugin project through Eclipse for the ODA Implementation & UI.
Have Tycho generate the poms etc for the plugin.
Now here's where I get muddy. I understand that there are two approaches
Manifest-First - which is the standard mechanism for defining a plugin's dependencies
POM-First - which provides dependencies via Maven's resolution mechanisms.
I'm not entirely sure where to begin trying to start doing this as I've never worked on developing an eclipse plugin.
One of the other questions I have is, how does a developer of an eclipse plugin (maven aside) leverage already existing third-party code (i.e. Apache HttpClient 4.x)? Do they have to download the jars, dump them into a directory within the project, add to classpath, then go from there or is there a "repository" mechanism similar to what is used with ivy, maven, gradle?
Thanks in advance and I apologize if I was rambling a bit with that.
Disclaimer: Your question is very broad, so it is impossible to answer it completely. Still, I can give you some hints so that you know what to search for.
In the Eclipse universe, the primary source for libraries (in the sense of binary dependencies) are p2 repositories. However, since p2 repositories are rarely used outside of the Eclipse context, you won't e.g. find a p2 repository on the Apache HTTP Client project's download page.
To account for this problem, there is the Eclipse Orbit Project which provides libraries used by Eclipse projects in p2 repositories.
If you can't find the library or library version in the Eclipse Orbit, you may also be able to use the libraries from Maven repositories. This is for example supported by Tycho via the pomDependencies=consider mechanism.
Note however that Eclipse plug-ins can only depend on libraries which are OSGi bundles. So if the library in the Maven repository is not yet an OSGi bundle, you need to convert it to an OSGi bundle first, e.g. with the maven-bundle-plugin and the Embed-Dependency mechanism.
The best way for an Eclipse plugin to consume libraries is as OSGi bundles. You just install those bundles into your target platform and reference them in the same way as eclipse.org plugins. Some of the library providers already offer their libraries as OSGi bundles. Absent that, you can typically turn a plain library jar into an OSGi bundle simply by adding a few manifest entries.
Depending on the build system you use and whether the libraries you need are available as OSGi bundles packaged into an online p2 repository, you can reference the URL and rely on your build to download and install the bundle.
If question of choosing a build system for Eclipse plugins with dependencies is still relevant:
Today I released new gradle plugin: Wuff version 0.0.1, which (I think) completely solves the problem. It allows to build Eclipse bundles and applications as they would be "normal" Gradle projects. All OSGi woodoo is auto-generated (although customizable). All dependencies are usual maven dependencies - regardless of whether dependency is OSGi or "normal" library.
