Problems configuring mybatis-spring in Red5

All,

I'm trying to configure MyBatis in an application running under Red5 server. I created an additional spring config file red5-ibatis.xml under WEB-INF which has these beans configured (as described in mybatis-spring user guide):

<bean id="hsqldbDataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="org.hsqldb.jdbcDriver" />
    <property name="url" value="jdbc:hsqldb:file:./db/hsqldb/testdb" />
    <property name="username" value="sa" />
    <property name="password" value="" />
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="hsqldbDataSource" />
</bean>

<bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
    <property name="mapperInterface" value="test.mappers.UserMapper" />
    <property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

When I run the server with the app deployed I get the following exception:

Exception in thread "Launcher:/testapp" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userMapper' defined in ServletContext resource [/WEB-INF/red5-ibatis.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'org.mybatis.spring.SqlSessionFactoryBean' to required type 'org.apache.ibatis.session.SqlSessionFactory' for property 'sqlSessionFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.mybatis.spring.SqlSessionFactoryBean] to required type [org.apache.ibatis.session.SqlSessionFactory] for property 'sqlSessionFactory': no matching editors or conversion strategy found

I'm not sure, but it looks like Spring doesn't see that the SqlSessionFactoryBean implements the FactoryBean interface and so cannot find the way to convert it to SqlSessionFactory?

Anyway, any ideas how to fix it?

OK, seems like I got it solved. Looks like I had all the Spring jars in my app WEB-INF/lib directory, which probably was bad because they are also in Red5 lib folder, so they were duplicated. After messing with my ivy.xml dependencies configuration and my Eclipse project deployment assembly settings, it started working.

Basically I had to remove standard Libraries/ivy.xml [*] from my Eclipse project and add two separate ones, which in my case were: ivy.xml [runtime] and ivy.xml [compile]. Then in my Eclipse project properties, in "deployment assembly" settings I chose to only deploy the dependecies from ivy.xml [runtime], which didn't contain Spring libraries.

No more exceptions.
