Weblogic 10.3.4 & Spring 3.0.6 & web.xml - spring

Question

currently working on developing a rest service that needs to be deployed on Weblogic 10.3.4. Using Spring 3.0.6 examples online but the basic loading of the DispatcherServlet seems to be causing problems with Weblogic.
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
The exception shown in the weblogic console window was:
<07-Nov-2011 20:29:33 o'clock GMT> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to STARTING>
log4j:WARN No appenders could be found for logger (org.springframework.web.servlet.DispatcherServlet).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Building using Maven and have all the spring-core/web/webmvc/context all defined as runtime dependent.
Also tried to copy the "org.springframework.web.servlet-3.0.5.RELEASE,jar" file to the bea\modules folder in an attempt to resolve runtime issues within weblogic.
Tried the weblogic-application.xml,
<prefer-application-packages>
<package-name>org.springframework.*</package-name>
<package-name>org.springframework.web.*</package-name>
<package-name>org.springframework.web.servlet.*</package-name>
<prefer-application-packages>
All that, same problem.
I noted that the release notes have stated that "This version of WebLogic Server supports Spring 3.0.", http://download.oracle.com/docs/cd/E17904_01/web.1111/e13852/toc.htm#BGGEAIJJ

Answer 1

Function code is limited by the size 64 KB in both version of Java 7 and 8. When our code exceeds more than 64 KB in function Compiler failed to compile the whole code and throws error as Unimplemented Byte Code
COMPILE ERROR:
ERROR MESSAGES/STACK TRACES THAT OCCUR :
=============== DEBUG MESSAGE: unimplemented bytecode ================
A fatal error has been detected by the Java Runtime Environment:
Note: Here function is consider as
1)Function is normal function one we write in jsp or java file.
2)Our normal jsp(Java Server Page) page is also treated as function when it is complied in java programming
Example:
// The Function Size Should Less Than 64KB
public static function myFunction(){
// Your Code
}
