Mule not rolling back JMS message after exception -


my flow consumes message based on cron expression , have deliberately added groovy code throw exception testing jms rollback. rollback doesn't return consumed message in queue. missing here ?

here mule flow supposed rollback mule message after exception encountered.

<jms:activemq-connector name="jmsconnector" specification="1.1" brokerurl="tcp://localhost:61616" /> <jms:endpoint name="testqueue" queue="test.queue" connector-ref="jmsconnector" />  <flow name="quartzbaseddelivery">     <quartz:inbound-endpoint jobname="deliveryjob" cronexpression="0 0/1 * * * ?">         <quartz:endpoint-polling-job>             <quartz:job-endpoint ref="testqueue" />         </quartz:endpoint-polling-job>     </quartz:inbound-endpoint>     <logger message="quartz found message delivery #[payload]" level="info" />     <scripting:component>                <scripting:script engine="groovy">                     throw new java.lang.runtimeexception();                 </scripting:script>     </scripting:component>     <file:outbound-endpoint path="/test/out" outputpattern="message-[function:datestamp].txt" />     <logger message="message deliverd" level="info" /> </flow>  <flow name="copyfile">     <file:inbound-endpoint  path="/test/in"/>     <byte-array-to-string-transformer />      <logger message="copyfile found message test queue #[payload]" level="info" />     <jms:outbound-endpoint queue="test.queue"/>  </flow>

here exception thrown flow -

    exception stack is: 1. null (java.lang.runtimeexception)   sun.reflect.nativeconstructoraccessorimpl:-2 (null) 2. java.lang.runtimeexception (javax.script.scriptexception)   org.codehaus.groovy.jsr223.groovyscriptengineimpl:323 (http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/script/scriptexception.html) 3. failed invoke scriptcomponent{quartzbaseddelivery.component.559022270}. component caused exception is: scriptcomponent{quartzbaseddelivery.component.559022270}. message payload of type: string (org.mule.component.componentexception)   org.mule.component.abstractcomponent:148 (http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/component/componentexception.html) ******************************************************************************** root exception stack trace: java.lang.runtimeexception     @ sun.reflect.nativeconstructoraccessorimpl.newinstance0(native method)     @ sun.reflect.nativeconstructoraccessorimpl.newinstance(unknown source)     @ sun.reflect.delegatingconstructoraccessorimpl.newinstance(unknown source)

in case jms messages won't redelivered originating queue rollback exception strategy because have quartz inbound endpoint, wich not transactional or reliable. can configure catch exception strategy , explicitly redeliver message. careful these scenarios because can create infinite loop.

source: rollback exception strategy

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
