The vendor is the first major organisation to provide support for the software, which will initially be limited to the US.
Geronimo and Gluecode have yet to achieve J2EE certification, but IBM executives expect the certification process to be finished within months.
IBM also said that it had donated Gluecode's management console to the open source project, and that the company could donate additional pieces of code in the future.
"As it makes sense we will certainly do it," Scott Cosby, transition executive at Gluecode, told vnunet.com.
IBM already owns an application server under the WebSphere brand, but the two products are complementary, according to Cosby. WebSphere targets high-end deployments and Gluecode goes after smaller applications.
"The business case for Gluecode is in serving markets that we cannot meet today," he said. "It opens new doors for us."
In a separate announcement at LinuxWorld, IBM revealed that it had reorganised its Linux sales operation.
The company has abandoned the old practice of selling open source products in predefined categories, such as mainframes, volume servers or application middleware, and will target specific problems within industry verticals.
