The Java 2 Platform Standard Edition (J2SETM) 1.5 is packaged with Sun Java System Web Server 6.1 SP11. The J2SE 1.4 has reached its End of Service Life (EOSL) and is hence deprecated. Therefore, when you upgrade or install your Web Server 6.1 SP11, the Java Development Kit JDKTM gets upgraded or installed automatically for the Solaris, Linux, and Windows platforms. For the HP-UX and AIX platforms, download the JDK from the respective platform vendors' web sites before installing the web server.
The 64-bit Solaris SPARC release of Sun Java System Web Server requires a 64-bit JDK. On all other platforms, a 32-bit JDK is required.
The web server has been certified with the following JDK versions:
Solaris (SPARC, x86, and AMD64): 1.5.0_16
Linux: 1.5.0_16
Windows: 1.5.0_16
HP-UX: 1.5.0.12–_21_mar_2008_11_52
AIX: 1.5.0 pap32dev-20080315 (SR7)
