When accessing the OracleAS 10g Rel 2 AS Console the client browser hangs with:
- a blank screen
- 500 Internal Server Error
Servlet error: Error instantiating servlet 'console' (servlet class not found, make sure it exists at <oracle home>/sysman/webapps/emd/WEB-INF/classes/oracle/sysman/eml/app/Console.class, in a jar in <oracle home>/sysman/webapps/emd/WEB-INF/lib/, in an orion-web.xml specified classpath or global server classpath)
If a blank screen is shown, the following errors might be seen in $ORACLE_HOME/sysman/log/em-application.log:
Sometimes the browser hangs as soon as the AS Console url is entered. Other times the AS Console login appears and the browser hangs immediately after login.
The startup of AS Console from the command line - emctl start iasconsole - works fine
The problem reproduces no matter which browser (IE, Mozilla, Netscape etc) is used.
