Description
The Sun GlassFish Enterprise Server 2.1.1 (Build 17 sges_ee-2_1_1-fcs-bin-b17-solaris-i586-03_jun_2009.bin) upgrade tool cannot migrate Portal Server 6.3.1 (JES4) applications from AS 8.1_02 (JES4).
This issue can affect the process of upgrading from Java ES 4 to Java ES 7 when updating Application Server 8.1 to GlassFish, and Portal server 6.3.1 and/or Instant Messaging are also installed. This problem may also affect other older applications when upgrading to GlassFish 2.x
The problem is caused by a design flaw in the GlassFish 2.x upgrade tool because it recreates the archive from exploded application bits during upgrade process. The jar signature then becomes invalid when the archive is recreated.
Solution
None. Either update the older applications before updating to GlassFish, or perform a new GlassFish installation rather than an upgrade installation, and then manually redeploy the older applications to GlassFish.
