how to define a GemFire index with xml

I tried to define an index in the spring-cache-server.xml:
<!-- region -->
<gfe:partitioned-region id="MyPartitionRegion" cache-ref="cache">
</gfe:partitioned-region>

<!-- index -->
<gfe:index id="myIndex" type="PRIMARY_KEY" cache-ref="cache"
expression="testId" from="/MyPartitionRegion" />

When I start the first server ,everything is OK.
When I start the second or the third server ,sometimes there's nothing wrong with it,but sometimes here comes the error:

Exception in thread "main" org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'myIndex': Invocation of init method failed; nested exception is com.gemstone.gemfire.cache.query.IndexNameConflict Exception: Index named ' myIndex ' already exists.

What should I do with the index...

Can you post your cache config?

spring-cache-server.xml:

<!-- cache -->
<gfe:cache id="cache" properties-ref="props"
cache-xml-location="classpath:cache-server.xml" />



cache-server.xml:

<!DOCTYPE cache PUBLIC
"-//GemStone Systems, Inc.//GemFire Declarative Caching 6.6//EN"
"http://www.gemstone.com/dtd/cache6_6.dtd">
<cache is-server="true">
<function-service>
<function>
<class-name>........</class-name>
</function>
<function>
<class-name>........</class-name>
</function>
</function-service>
</cache>

It looks like a bug but I am unable to reproduce the problem with a simple cache configuration with 2 instances running locally on different ports. It would help to see your property settings, logs, etc.

I've got two servers and some regions persist to disk.
When I start the second server after the first server has already started, it's OK.
When I restart these servers, they recovered data from disk. So they started at the same time, and the second server failed to start.

However now I use API to create index instead, and it works.

OK. I created a JIRA for this https://jira.springsource.org/browse/SGF-94

Thanks~ :)
