    Ehcache on Fuse ESB

    Farha Jahan Newbie

      How can I work on Ehcache in Fuse ESB 4.4??

        • 1. Re: Ehcache on Fuse ESB

          There is the camel-cache component which uses EHCache

          http://camel.apache.org/cache

            Yeah..I have read that but couldn't get anything out of it dat would be my help.

             

             

            I have a working use case that moves a file from input folder to output folder through XSLT moving through activemq input and output queue respectively. I want the transformed file to go to the cache and then to output queue.

            How can I do this? kindly help!

              In one route you send the file to the cache

               

              You need to specify a cache key and an operation (ADD) to add it to the cache.

               

              And in another route you consume from the cache using that same key.

                Thanks fo the reply.

                 

                1

                4               <to uri="cache:cache key ?"/>

                5 </route>

                 

                 

                As above, i need to route from xslt to a cache. How to define cache in a apt way. ( still how to create & syntax ). Also defining ADD for the same.

                 

                Help out by modifying the above code. (Line 4 )

                  Hi

                   

                  You need to set these 2 headers as shown:

                   

                  1

                    Hi Dav

                     

                    I think , both the headers have to be embedded into ' To Uri tag '. Since how both the headers are linked with it.

                     

                    By the way it doesn't worked. Since the bundle is still in failure.

                     

                    FYI: I am using SMX4 and Deploying using Camel-Blueprint.

                     

                     

                    Help out.

                      You have installed the camel-cache feature right? That must be installed first.

                       

                      This can be done from the shell using the following command:

                      features:install camel-cache

                        Yeah I have done that. And it's active.

                          Do you see any errors/stacktraces or the likes from the log? I assume when you say failure its your Camel bundle that is in failed state?

                            In the osgi:list it's showing

                              The log file is in the data/log directory and named servicemix.log.

                               

                              You may take a look in that log file to look for any kind of failure/error.

                               

                              In the shell there is a log command you can use as well.

                              log:display

                              log:display-exception

                              As well as a log:tail (in one of the latest releases)

                               

                              I suggest to check that servicemix.log and see if there is any hint why your application is in failure state.

                                  It seems you are using EHCache 2.4.3. Did you install that by yourself?

                                   

                                  EHCache is not osgi compliant out of the box. And you need to use the OSGi bundles from this repo

                                  http://repo2.maven.org/maven2/org/apache/servicemix/bundles/org.apache.servicemix.bundles.ehcache/

                                   

                                  A new bundle for EHCache 2.4.3 is on the way.

                                   

                                  I suggest to use the default installation from Fuse ESB as its tested and certified to be working together.
