This is the repository for latest version of HTTPBC (version 3.0.0) based on Grizzly2.
Also, please have a look to this class to provide support for other keystore type.
I will be happy to validate your pull request ;-)
PS : Don't forget to create a ticket in JIRA before going further !
PS2 : You can build components in version 3.0.0 using Maven 3.x (it's not the case for components in 2.4.x). You still have to set profil to openesb to retrieve some common artifacts.
