I am happy to announce the jexl based implementation of Everit expression-api.

We have used the mvel based implementation till now. Although it is 3x faster than jexl, we decided to go with the last one due to the following reasons:

• To code of jexl is clean. In the future, we will be able to add the same optimizations as MVEL has. We could not really do bugfixing on MVEL as its code is messy.
• As jexl does not have optimizers at the moment, it works well within OSGi. We had serious issues with MVEL and due to the messy code, it was truly hard to fix them.
• Jexl uses the same syntax for inline maps and arrays as Javascript does. If we use jexl in templating-html, we will be able to use the template with a templating engine written in javascript later.

We are happy to announce the first public release of Blobstore components. Blobstore allows the programmer to read and write binary large objects within atomic transactions.

Everit Blobstore has in-memory and JDBC-based implementations. While the in-memory implementation can be used to write unit tests, the other one supports several relational database types: Apache Derby, Hsqldb, MySQL, PostgreSQL, Microsoft SQLServer, Oracle

As always, the artifacts are available on maven-central.

For more information, see the site of Blobstore: http://www.everit.org/blobstore.html

New versions of the configuration projects are available:

• coding-conventions: 9.0.7
• maven-main: 7.0.7
• maven-oss: 6.0.7

The new version of coding-conventions and maven-main exclude the com.sun:tools dependency of Checkstyle. By doing that the m2e code quality extensions can auto-configure eclipse on any system.
