Red Hat unveiled the Red Hat Application Server in 2004 based on the open source Jonas project.
Although it was expected that the Red Hat product would be discontinued, the company declined to comment on the topic when it revealed the $420m Jboss acquisition.
Szulik justified the move by pointing out that the Jboss software is more advanced that the Jonas code.
"We are very impressed by the people at Jboss and the technical capabilities of that organisation," he said.
"We think they are superior to the Red Hat Jonas implementation. What we would like to do is take the best from the Jonas implementation and make that available to the Jboss developer teams where that makes sense."
Jboss is best known for its open source Java application server, but also offers a slew of middleware applications including a portal and messaging server.
Red Hat also offers several middleware products including a directory and identity server. Red Hat's range of middleware products is mostly based on the Netscape Enterprise Suite that the company acquired from AOL in October 2004.
The Red Hat and Jboss application servers is one of the most obvious areas where the two vendors' products overlap.
