1 Upgrading WebLogic Server 6.x to Version 7.0
1-26 BEA WebLogic Server 7.0 Upgrade Guide
 There were no local interfaces in 6.0, but they exist in 6.1 and 7.0.
 Remote relationships do not exist in 6.1 and 7.0.
 The new implementation of read-only beans in WebLogic 7.0 does not require 
NOT_SUPPORTED for a transaction attribute. It also doesn't do exclusive locking, 
but gives each transaction its own instance of the read-only bean to use.
 In pre-2.0 final versions of our EJB implementation you could refer to a CMP or 
CMR field in a 
EJB QL query without using a qualified path. However, as of the 
final specification, all 
EJB QL queries must have a qualified path.
 The new implementation of read-only beans in WebLogic 7.0 does not require 
NOT_SUPPORTED for a transaction attribute. The new implementation also does 
not do exclusive locking, but gives each transaction its own instance of the 
read-only bean to use.
If you have trouble with a servlet within the scope of application deployment see 
“Deployment” on page 1-24.
weblogic.management.configuration.EJBComponentMBean Changes
Beginning in Weblogic Server 6.1 and continuing in WebLogic Server 7.0, the 
interface 
weblogic.management.configuration.EJBComponentMBean changed 
so that it extends both 
ComponentMBean and EJBContainerMBean. Any methods 
that implement 
EJBComponentMBean (for example, 
getVerboseEJBDeploymentEnabled) must be changed to support 
EJBContainerMBean when you port from WebLogic Server 6.0 to 7.0.
max-beans-in-cache Parameter
In WebLogic Server 7.0 the max-beans-in-cache parameter controls the maximum 
number of beans in the cache for Database concurrency. In earlier WebLogic Server 
versions, 
max-beans-in-cache was ignored; the size of the cache was unlimited. 
You may need to increase the size of this parameter.
