java.lang.NoClassDefFoundError: Could not initialize class oracle.apps.fnd.profiles.Profiles

After changing the IP address in Oracle Apps 11i and we dont need to run the autoconfig we got the following error message:

JSP Error:
--------------------------------------------------------------------------------
Request URI:/OA_HTML/AppsLocalLogin.jsp

Exception:
java.lang.NoClassDefFoundError: oracle.apps.fnd.profiles.Profiles (initialization failure)



To solve the issue we modified the file
$IAS_ORACLE_HOME/Apache/Jserv/etc/jserv.properties

and commented the following line the restart the Apache server:
#wrapper.bin.parameters=-DLONG_RUNNING_JVM=true
