What classes do you think you need to access from j2ee.jar that are not
already available to web applications?

If this is the j2ee.jar file from J2EE 1.3, it already includes a complete
copy of Tomcat 4, so duplicating the classes will cause nothing but grief.

Hi, Wells, 



Thanks for your response. 



It took me awhile trying to figure how the CLASSPATH relates with the 
problem. I build up the JSP application using Tomcat 3.x with the standard 
procedure. Nothing inside the project is set up in the CLASSPATH. I don't 
know what you means by "all j2ee platform classes". Are the classes used 
j2ee APIs? 



Thx. 



Vernon

RE: The 4.0b5 doesn't recognize a servlet class

[Vernon Wu]

Hi, Aditya,


I think you mean the two jar files: jasper-runtime.jar and namingfactory.jar in the tomcat4.0/lib.

I use the JBuilder as the IDE where I can check any syntax errors or not.I have j2ee.jar inside of the JBuilder library setting. When I want to deploy it, I compile it again using ant, where the j2ee.jar is from the jdk1.3 directory. AfterIchange the j2ee.jar pointto the common/lib (a copy of the jar isin the directory), and include the two jars from tomcat/lib, and recompile it, the result is the same: recycle the tomcat and have the following error messages:

Catalina.start: LifecycleException: start: : java.lang.NoSuchMethodErrorLifecycleException: start: : java.lang.NoSuchMethodError

DoI get the message right?



Thanks.

  I experienced the same problem. It's due to a class loader issue. 
  Multiple 
  
  class loaders have been introduced in V4.0 to implement the 
  requirements 
  
  found in Section 9.6.2 of the Servlet 2.3 Spec. These class loaders 
  are 
  
  used to load all of the jars and classes rather than using the 
  CLASSPATH. 
  
  
  
  I was able to resolve this problem as follows : 
  
  
  
  - Add all supporting jars for your web application (except J2EE 
  jars) to 
  
  the /WEB-INF/lib directory rather than including them in the 
  CLASSPATH 
  
  - Add all of the required classes for your web application to the 
  
  /WEB-INF/classes directory rather than including them in the 
  CLASSPATH 
  
  - Add the j2ee.jar from the /j2sdkee1.3/lib directory to the 
  
  TOMCAT_HOME/common/lib directory. All J2EE platform classes must be 
  placed 
  
  in the common/lib or common/classes directories rather than with 
  the web 
  
  application.

  I move one our small JSP application from 3.x to 4.0b5 for the
