Cannot instantiate Gateway in 2.0.0M1 w/ Spring 3.0.0RC3

[Solstice]

When attempting to instantiate a Gateway, the following results:


java.lang.NoClassDefFoundError: org/springframework/core/convert/support/DefaultConversionService

Gateway Configuration snippet:



<si:gateway id="lookupProdGateway"
service-interface="com.company.gateway.IProdLookupGateway"
default-request-channel="ProdLookup-Request"
default-reply-channel="ProdLookup-Response" />




It seems that SI 2.0M1 requires Spring 3, yet Spring Core seems to have dropped the DefaultConversionService object from its latest release.


Here is the full stacktrace:

The DefaultConversionService was renamed in Spring 3.0 RC3 (or in a nightly after that). So either use a nightly snapshot of SI or wait for a snapshot which has this addressed.

[Solstice]

Thanks for the suggestion, Marten. That worked.

We will be releasing Spring Integration 2.0 M2 sometime in December. It will depend on *at least* RC3 but hopefully even Spring 3.0 GA.
