JSP errors in newly installed E-Business Suite 11.5.10 QU3

Oracle E-Business Suite 11.5.10 QU3 is downloadable from eDelivery, and installs a fresh 11.5.10 Quarterly Update 3 with a 10g ( database.

Unfortunately, your fresh install will result in java.lang.UnsupportedClassVersionError for all JSP pages (although servlets will work fine).

In the Java world, classes compiled with Java 5 but running under Java 4 can return the “Unsupported major.minor version 49.0” error, as the classes are not being loaded as they are using Java 5 specific features. To rectify this, simply edit $IAS_ORACLE_HOME/Apache/Apache/bin/ and configure it to use JDK 1.5 instead of JDK 1.4 (both JDKs are already installed under $COMMON_TOP/util/java):

OLD VALUE: JSERVJAVA=/d01/applmgr/devcomn/util/java/1.4/j2sdk1.4.2_04/jre/bin/java

NEW VALUE: JSERVJAVA=/d01/applmgr/devcomn/util/java/1.5/j2sdk1.5.0_06/jre/bin/java
Applicable Versions:
  • Oracle E-Business Suite 11i (11.5.10)
