Monitoring camel routes using camel-bam
1 year ago

By Hadrian Zbarcea
Last week I got a question from an Apache Camel user about ways to get statistics on the activity on a route, including errors. There are quite a few ways to achieve that. First there are obviously the logs, but they are mostly useful to investigate a particular problem. Then there are the performance counters (defined in the org.apache.camel.api.management package) that could be obtained either via the JMX support or even exposed as a RESTful ...

Apache Rave a new ASF Top Level Project
1 year ago

By Hadrian Zbarcea
After one year of hard work, Apache Rave graduated from incubation. Although the resolution was approved by the ASF board last week, the official announcement came only this morning (also featured on NASDAQ GlobeNewswire).

First initiated by Ate Douma and discussed at ApacheCon 2010 in Atlanta, the idea quickly captured the imagination of a group of developers and the proposal was submitted in February 2011. After a bit more then a year and a few ...

How to protect the release GPG key
1 year ago

By Hadrian Zbarcea
Recently I have been asked about how I handle the gpg key I use for Apache releases. For what is worth, the question popped up in the context of a few other community members taking on the release manager role. As those of you that follow Apache Camel already know the Camel PMC decided to actively support and issue patch releases for the two latest minor branches.

But I digress. As I mentioned, I don't keep my private key on my laptop, but on an ...

The Case for Patch Releases
1 year ago

By Hadrian Zbarcea
A new patch release of Apache Camel, version 2.8.1 was released last week. I didn't announce releases in a while. Why write about camel-2.8.1 then?

The reason is that the Apache Camel community didn't produce patch releases in the past (we only did it for the 1.6.x version before discontinuing support for the 1.x versions). We actually started producing patch releases back in April for camel-2.7.x. At the time, I wasn't sure if and how this will ...

Congrats Master Melegrito!

By Hadrian Zbarcea
Personal things don't usually belong here, but this is a bit special. I am also still sore after this weekend.

Once a year, me and Ama have the opportunity to go with our instructor, 4th Dan Tae Kwon Do Master Josh Geeson, to train in self defense against stick and knife with Master Julius Melegrito, event organized in Charlotte, NC by Master Evins.

The seminar was a real treat as expected. Master Melegrito's speed and technique are amazing. After ...

Annotation for the Claimcheck Pattern
1 year ago

By Hadrian Zbarcea
The claimcheck pattern is described in the EIP book Camel is based on. The way it is described, the pattern uses a data store which means that it applies mostly to local processing. However, in most of the cases, at least in my experience, the processing is not local so one needs to retrieve the original message at a different location where access to the data store is not necessarily possible.

As a bit of background, the commonly used analogy for the ...

Apache Camel 2.5.0 Released
2 years ago

By Hadrian Zbarcea
The 2.5.0 release of Apache Camel is finally out. It is the result of some two and a half months of improvements since the last release in July. You can check the release notes for more details and give it a try.

The PMC is planning to focus now on releasing the 3.0 version of Camel in Q1 of next year. The 2.x version will continue to be actively improved for the foreseeable future (at least through 2011) and we plan to have another camel 2.x release ...

Should you getIn or getOut?
2 years ago

By Hadrian Zbarcea
From recent posts on the camel users@ mailing list there seems to be some confusion related to the use of getIn() and getOut() on a Camel Exchange. The question is relevant to developers who want to implement a processor and need to understand what should happen with the result of their processing. There is a wiki page that attempts to explain the usage of the two methods, but sadly that mostly fuels the confusion than clarifies anything. The page ...

Take the Apache Camel Survey!
2 years ago

By Hadrian Zbarcea
A new Apache Camel release is just around the corner (version 2.5.0) and recently we announced taking the 1.x branch off life support. Therefore the race is on to deliver a new major version, Camel 3.0 early in Q1 2011 (see roadmap).

To that end the Camel PMC worked on a survey last week intended to get a better feel of how the community is using Apache Camel, what the major issues are (documentation, I know) and what improvements and new features you ...
