Answer 1

Try to use same version for all Spring dependencies. Now you are using 2.5 and 2.5.6.

Answer 2

The jar file that own AliasRegistry is from spring-core-2.5.jar and from your libraries output, it seem you have that. I have once with mixed version 3 and version 2.5 of spring causing issue. But the exceptions are gone once the correct version are in place.
I have struts1.3 and hibernate, I will comment based on our difference and to see if this give you any help. But with my libraries placed in lib, hibernate works fine though. So here goes,
Get the same version for this.
commons-digester-2.0.jar
commons-beanutils-1.7.0.jar
which version of javassist.jar do you have? I have javassist-3.12.0.GA.jar
spring-beans-2.5.6.jar, try get exact version of spring-beans-2.5.jar
which exact version of hibernate3.jar do you have? I'm using hibernate-core-3.6.4.Final.jar
These are libraries for struts1, are you using these together with struts2?
struts-tiles-1.3.10.jar
struts-taglib-1.3.10.jar
struts-extras-1.3.10.jar
commons-validator-1.3.1.jar
these seem like packages from struts2 which is the one you are using, yes?
struts2-core-2.3.1.2.jar
xwork-core-2.3.1.2.jar
try to get the exact version of spring-tx, that is spring-tx-2.5.jar which is the same with the rest of spring jars.
