Migrating API and specifications
Migrating application programming interfaces (APIs) and specifications involves moving to the current Java™ component level as well as to other technologies that WebSphere® Application Server Versão 9.0 supports. If your existing applications currently support different specification levels than are supported by this version of the product, it is likely that you must update at least some aspects of the applications to comply with the new specifications.
In many cases, IBM® provides additional features and customization options that extend the specification level even further. If your existing applications use IBM extensions from earlier product versions, it might be necessary for you to perform mandatory or optional migration to use the same kinds of extensions in Versão 9.0.
WebSphere Application Server Versão 9.0 supports Java Platform, Standard Edition (Java SE) 8 and Java Platform, Enterprise Edition (Java EE) 7.
See APIs de modelo de programação e especificações for a summary of the specifications and API documentation supported in current and prior product releases.
