Users need a Java client to run the Forms-based content in Oracle E-Business Suite.  With Oracle JInitiator 1.3 out of Premier Support as of July 2009, Apps users must run the native Sun Java Runtime Engine (JRE) to access this content.

In early 2008 we relaxed our certification and support policy for the use of the native Sun JRE clients with the E-Business Suite. The policy reflected a switch from certifying specific JRE versions for the E-Business Suite to specifying minimum versions, instead. This permits E-Business Suite users to run any JRE release above following minimum certified levels, even later ones that Oracle hasn't explicitly tested with the E-Business Suite:

• JRE 1.5.0_13 and higher
• JRE 1.6.0_03 and higher

Under our current policy, Oracle E-Business Suite end-users can upgrade their JRE clients whenever Sun releases a new JRE release on either the 1.5 or 1.6 versions. EBS users do not need to wait for Oracle to certify new JRE 1.5 or 1.6 plug-in updates with the E-Business Suite.

Known E-Business Suite Issues with JRE 1.6.0_18

We test every new JRE release with both E-Business Suite 11i and 12.  We have identified a number of issues with JRE 1.6.0_18.  If you haven't already upgraded your end-users to JRE 1.6.0_18, we recommend that you to keep them on a prior JRE release such as 1.6.0_17 (6u17).
