While doing the migration to Linux I was stumped by an error. I was not able to login using Self Service but was able to login using dev60/f60cgi. This error kept haunting me and giving headaches for two weeks.
The error was as follows:
oracle.jsp.JspServlet: initOSS: Caught throwable in AppsLocalLogin.jsp : java.lang.NoClassDefFoundErrorjava.lang.NoClassDefFoundErrorat oracle.apps.fnd.sso.SSOManager.getAppsServletAgent(SSOManager.java:1998)at oracle.apps.fnd.sso.SSOManager.getLoginUrl(SSOManager.java:338)at _oa__html._AppsLocalLogin._jspService(_AppsLocalLogin.java:483)at oracle.jsp.runtime.HttpJsp.service(HttpJsp.java:119)at oracle.jsp.app.JspApplication.dispatchRequest(JspApplication.java:417)at oracle.jsp.JspServlet.doDispatch(JspServlet.java:267)at oracle.jsp.JspServlet.internalService(JspServlet.java:186)at oracle.jsp.JspServlet.service(JspServlet.java:156)at javax.servlet.http.HttpServlet.service(HttpServlet.java:588)at org.apache.jserv.JServConnection.processRequest(JServConnection.java:456)at org.apache.jserv.JServConnection.run(JServConnection.java:294)at java.lang.Thread.run(Thread.java:534)
I had enabled jserv logging but it was not giving any insights. After 2 weeks of intense followup with Oracle Support it turned out that while the copy of $JAVA_TOP/COM is done from Windows to Linux the COM directory needs to be moved to lowercase i.e. com as Windows is case insensitive and Linux is not.
Oracle Support has created a metalink note 604529.1 which is not published yet.
