Outbound connection from JBoss AS

[gvseghbr]

Hi,

I want to access a REST interface from within an EJB. This EJB is deployed on a local JBoss AS7.

Extra difficulty, I have to use a certificate to connect to the REST interface's server.

Is there a possibility to use JBoss AS to manage the outbound connections? JBoss' remoting subsystem? outbound-socket-binding?

How can I get an instance of such a connection from within my EJB?

Kind regards,

Gregory

You can use Apache HttpComponents from within the EJB, or use Jboss Resteasy client.

For the certificate you have to use a java keystore and set SSL system properties in jboss start script.

Ex.: -Djavax.net.ssl.keyStore=/path/to/keystore.jks -Djavax.net.ssl.trustStore=/path/to/truststore.jks -Djavax.net.ssl.keyStorePassword=password -Djavax.net.ssl.keyStoreAlias=alias

Hi Fabrizio,

First of all, thank you for the response.

However, I was hoping there would be a more "managed" solution to this. What I had hoped for, was to be able to use JBoss’ security realms for the SSL and something similar to invoking remote EJBs.

In the option that you propose, I have to manage the ConnectionManager and all connections myself.

Kind Regards,

Gregory

I use the REST-Easy client from within JBoss to consume external REST services.  It's built on top of Apache Http client so you can use a variety of options including setting headers etc.    I haven't used it with SSL but looking at this StackOverflow question it looks easy enough: http://stackoverflow.com/questions/12369495/accepting-a-self-signed-certificate-in-java

I also would use REST-Easy client.

Only a precision. In StackOverflow question they talk about SSL configuration server side. From EJB perspective, it needs only SSL client side. It is sufficient to set the system properties as I said and automatically REST-Easy/Apache HttpClient inherits them.

You need to check out the apache http4 docs to see what params you need to set.  I shouldn't have included that StackOverflow link - it's not very helpful, sorry. 

To configure the apache HTTP4 executor that underpins a RESTeasy request you pass in an ApacheHttpClient4Executor instance as the third parameter into the RESTEasy ProxyFactory.create() method.
