There are 2 projects: dubbo-rpc-jms and dubbo-rpc-activemq. dubbo-rpc-jms has only 1 file on META-INF/dubbo (org.apache.dubbo.rpc.Protocol) and JmsImplementor interface is an extension point. Doesn't have any implementation defined in the configuration file.
Question: ActivemqJmsImplementor is the only implementation of JmsImplementor. I'm not sure if I should move ActivemqJmsImplementor to the same project as JmsImplementor and create the file org.apache.dubbo.rpc.jms.implementor.ActivemqJmsImplementor on META-INF/dubbo. Is it ok? Exception on dubbo-rpc-jms org.apache.dubbo.rpc.RpcException: Fail to create JMS Connector to jms:// 127.0.0.1:5344/org.apache.dubbo.rpc.protocol.jms.JmsService?version=1.0.0, cause: No such extension org.apache.dubbo.rpc.protocol.jms.implementor.JmsImplementor by name activemq On Mon, Jun 10, 2019 at 1:52 AM Huxing Zhang <[email protected]> wrote: > Hi, > > Sorry for the late reply, we had dragon-boat festival vacation last week. > > On Sat, Jun 8, 2019 at 10:32 AM Daniela Morais <[email protected]> > wrote: > > > > Hi, > > > > Today I did: > > * The task of merging dubbo-rpc-jms (#3765) overlapped with collecting > > metrics > > > > Questions: > > 1) Is there any doc that can help me with dubbo-rpc-jms?
