Hi,

You need provide more details about what you do here?
e.g. which feature you installed, what your bundle looks like and what  
you exactly want to do.

Without detailed infos we can't provide any useful help.

Thanks Freeman-2,

The conflict is solved and I am able to move the file from activemq input
queue to cache and then  
 retrieve
 the file from the cache to output queue. 

But when I am trying to pass the file from xslt to the cache, I am not able
to retrieve it.

This is the code:

<route>
                <from
uri="xslt:file:D:\ESB\apache-servicemix-4.4.0-fuse-00-27\design.xsl"/>


                      <setHeader
headerName="CACHE_OPERATION"><constant>ADD</constant></setHeader>
                      <setHeader
headerName="CACHE_KEY"><constant>myKey</constant></setHeader>

                <to uri="cache://myCache"/>
        </route>
      
        <route>
                <from uri="cache://myCache"/>   
                      <setHeader
headerName="CACHE_OPERATION"><constant>GET</constant></setHeader>
                      <setHeader
headerName="CACHE_KEY"><constant>myKey</constant></setHeader>
	          <to uri="activemq:queue:outputQueue"/> 
	  </route>

Please help.

Hi,

How you package your bundle?
The java.lang.ClassCastException:
net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory cannot be
cast t
o net.sf.ehcache.distribution.CacheManagerPeerListenerFactory

generally indicate that RMICacheManagerPeerListenerFactory and  
CacheManagerPeerListenerFactory get loaded by different classloader,  
my gut feeling is that your customer bundle embed some cache jar and  
this conflict which the one in OSGi container.

Anyway, a runnable testcase is absolutely more helpful here.

Re: Getting Exception in cache feature in Fuse

I have to  move a file from activemq input queue to cache and then retrieve
the file from the cache to output queue.

I have installed the Fuse cache using feature:install camel-cache.

I am using camel-blueprint to move the file. The blueprint bundle is created
while the camel-cache  bundle is not created.


Please help.
