Dependency hell (Class not found)

[linuxmank]

Hi All,

Thanks in advance,

I been trying to solve this from many days now, and now I think my brain is stuck.

[Marten Deinum]

Pleae use [ code][/code ] tags when posting code, that way it remains readable. Can you post your manifest file? You have included the correct import packages/bundles in your manifest didn't you? You are also mixing spring versions (judging from the bundles yu posted) in general this is a bad idea... Either use 2.5.6 or 2.5.6.SEC01 but don't mix jars...

It looks like I am able to use BasicDataSource to get connection and use jdbc but the moment i uncomment the below i get the above error

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate" >
<constructor-arg><ref bean="dataSource" /></constructor-arg>
</bean>
