How to deploy two different Spring Batch wars to one Tomcat?

[piffta]

Hi,

I’m using Spring Batch 2.1.5, Spring Batch Admin 1.2.0, Spring Batch Infrastructure 2.1.1 and Tomcat 6.0.32.

I want to deploy two different Spring Batch WAR applications on same Tomcat. And I get following exception:

Caused by: org.springframework.jmx.export.UnableToRegisterMBe anException: Unable to register MBean [org.springframework.batch.admin.jmx.BatchMBeanExpo rter@1c70e21] with key 'batchMBeanExporter'; nested exception is javax.management.InstanceAlreadyExistsException: spring.application:name=batchMBeanExporter,type=Ba tchMBeanExporter


I have defined beans of type BatchMBeanExporter in both applications (beans ids are changed).

Somebody had similar problems?
Could someone give me some advice about this?

Thanks in advance.

looks like a conflict, did you try the domainName property in BatchMBeanExporter?

BTW, you should use the same version for all your Spring Batch dependencies.

Hi Arno,
Thanks for the answer.

I change values of Spring Batch core and Spring Batch Infrastructure to 2.1.8 and try to change value of property 'domain', but problem is not solved.

Here is the BatchMBeanExporter bean definition:

<bean id="customBatchMBeanExporter" class="org.springframework.batch.admin.jmx.BatchMBeanExporter"
        p:jobService-ref="jobService"
        p:defaultDomain="com.telegraaf.relatieplanet.findmatches" />

I got the same exception after these changes:

Caused by: org.springframework.jmx.export.UnableToRegisterMBe anException: Unable to register MBean [org.springframework.batch.admin.jmx.BatchMBeanExpo rter@1c70e21] with key 'batchMBeanExporter'; nested exception is javax.management.InstanceAlreadyExistsException: spring.application:name=batchMBeanExporter,type=Ba tchMBeanExporter

Should I re-define some more beans? Or, should I change some more properties in BatchMBeanExporter bean definition?

is there's a <context:mbean-export/> somewhere?

[piffta]

Yes, there is a <context:mbean-export /> at the begin of spring batch context file.
I'm getting the same exception with and without this.

try to set the default-domain attribute of mbean-export to a different value in each web app.

Hi,
I try following things:

<context:mbean-export default-domain="test.mbean.bean1" registration="ignoreExisting" />

and

<context:mbean-export default-domain="test.mbean.bean1" registration="replaceExisting" />

with and without custom definition of
org.springframework.batch.admin.jmx.BatchMBeanExpo rter

But, it didn't help...

I decide to change implementation of these background services (they will be run as command line services).

Thanks for your help.
