Custom plugin classloader issue

Hi All,
   I am stuck at a strange issue, I have my custom Query Component that has
to load spring application context for some additional runtime filtering of
records.
   I have included my jars as dependency in solrConfig.xml, SOLR is able to
load my plugin but spring appplication fails to load with error.

This is how my solrConfig looks
  <lib path="${solr.solr.home}/mylib/myapp.jar" />

Following is the stack trace, any pointer of what is causing the issue

org.springframework.beans.factory.BeanDefinitionStoreException: IOException
parsing XML document from class path resource
[com/myapp/spring/myapp-spring-master.xml]; nested exception is
java.io.FileNotFoundException: class path resource
[com/myapp/spring/myapp-spring-master.xml] cannot be opened because it does
not exist

com.myapp.spring.MyAppApplicationContextAware.loadApplicationContext(MyAppApplicationContextAware.java:69)
        at

Thanks Chris, that worked. Loaded my Spring Application context with plugin
class loader. Was trying to resolve this since a day, and you resolved it
in a minute :)

Thanks

when you instantiate your Spring context, you have to make it aware of the 
ClassLoader you get from the SolrResourceLoader so that Spring knows where 
to find the resources in your jar.

first google result i found about specifying a classloader when 
instantiating spring...
