Error creating bean with name 'sessionFactory' : MalformedParameterizedTypeException

Question

ANY advice would be apprecated. I'm stumped...

Problem

On my laptop, anytime our application tries to load the application-config.xml, I get a java.lang.reflect.MalformedParameterizedTypeException.

The EXACT same code works on my desktop and my coworker's desktop/laptop. But on my laptop it throws this error. Since my laptop and desktop are the exact same development environment (Java 1.6 Maven project in Eclipse on Mac OS X Leopard), I've narrowed down the causes by doing the following:

• Checked out a fresh project from Subversion (so no code differences)
• Copied over and replaced my entire Eclipse directory (so no Eclipse version/plugin differences)
• Copied over and replaced my entire .m2 directory (so no maven/project dependency differences)

What could possibly be causing this error in one place but not the other? Below is a snippet of the related beans and error...

                to arrive at an appropriate value. Though maxStatements is the JDBC standard 
                parameter for controlling statement caching, users may find c3p0's alternative 
                maxStatementsPerConnection more intuitive to use. -->

EDIT:

Update - I just found another clue, none of our database-related JUnit tests work. On my desktop they all pass. On my laptop, they all fail with the following exception:

java.lang.NoSuchMethodError: org.springframework.beans.factory.annotation.InjectionMetadata.<init>(Ljava/lang/Class;Ljava/util/Collection;)V

Any and all suggestions welcome! Thanks!

Answer 1

I would assume you have wrong spring jars - perhaps one for spring 2.5 and one for 3.0. The classloader loads, say, spring-core for version 3.0, and the rest for 2.5. This would result in such errors.

I'd suggest going through your maven dependency graph and remove all redundant ones. If necessary, use <exclusions> in your pom.

Before that clean your project on all machines.
