Java: Eclipe's notion of classpath 101

In Eclipse, if you don't specify the build path, your classes by default will be placed in the base classpath of your project module. E.g.
C:\workspaces\myproject\myModuleEJB\classes\xxx

Therefore, your base classpath is C:\workspaces\myproject\myModuleEJB\classes\xxx

Consider two spring config source folders :
C:\workspaces\myproject\myModuleEJB\testsrc\spring\testApplicationContext.xml
C:\workspaces\myproject\myModuleEJB\configsrc\spring\businessRules.xml

testApplicationContext.xml is referring to businessRules.xml e.g.

testApplicationContext.xml
===================

<bean id="businessRules" init="false" class="org.springframework.context.support.ClassPathXmlApplicationContext">
  <constructor-arg>
     <list><value>spring/businessRules.xml</value></list>
  </constructor-arg>
</bean>

both testApplicationContext.xml and businessRules.xml are compiled by Eclipse into
C:\workspaces\myproject\myModuleEJB\classes\spring\testApplicationContext.xml
C:\workspaces\myproject\myModuleEJB\classes\spring\businessRules.xml

therefore, if testApplicationContext.xml wants to refer to businessRules.xml, the testApplicationContext.xml has to refer to the base classpath location of businessRules.xml
ie. /spring/businessRules.xml

eclipse: Installing JBoss Tools (formerly known asn JBoss IDE or Hibernate Tools) and SpringIDE via Update Manager

Hibernate tools can be obtained from JBoss tools. To add JBoss tools in eclipse, add this as a "Remote Site" in your Eclipse Update Manager
