E-Business Suite Page Not Found message when opening login page

 This error can be show in two ways
Page Not Found

Or 

500 Internal Server Error - java.lang.NoClassDefFoundError on Login 



Solution 1

In My Computer, navigate to $INST_TOP\apps\servername\ora\10.1.3\j2ee

There are three directories under this j2ee directory: forms, oacore and oafm.

Under each of these directories (forms, oacore and oafm), there are directories named forms_default_group_1, oacore_default_group_1 and oafm_default_group_1 respectively. 

Under each of these default_group_1 directories, there is a directory called ‘persistence’.

In these three ‘persistence’ directories, there are files with extension ‘.lock’.

Delete the files with the ‘.lock’ extension.

Then log onto E-Business Suite. The application loads.

Solution 2

You can disable the use of the Distributed JVM cache by changing the line in $ORA_CONFIG_HOME/10.1.3/j2ee/oacore/config/oc4j.properties that says LONG_RUNNING_JVM=true to LONG_RUNNING_JVM=false.

eg \oracle\Test\inst\apps\servername\ora\10.1.3

Note: This is recommended only as a short term workaround and for determining if the problem is with the java object caching or not.
