To create java project you can use maven archetypes





mvn archetype:generate -DarchetypeGroupId=org.apache.camel.archetypes \ -DarchetypeArtifactId=camel-archetype-spring -DarchetypeVersion=2.22.0 \ -DarchetypeRepository=https://repository.apache.org/content/groups/snapshots-group

<route> <from uri="mqtt://test?host=tcp://test.mosquitto.org:1883&subscribeTopicName=fabryprog-iota/test"/> <setHeader headerName="CamelIOTASeed"> <constant>9HIAWQJHGOPQVPWNCLKNVVMZZCUJXGUXYGJQNVXMWWUWXZUVQDBVAWBEGBPHWMXSYECPGZMJMNYHLQMVN</constant> </setHeader> <setHeader headerName="CamelIOTAValue"> <constant>0</constant> </setHeader> <setHeader headerName="CamelIOTAToAddress"> <constant>LXQHWNY9CQOHPNMKFJFIJHGEPAENAOVFRDIBF99PPHDTWJDCGHLYETXT9NPUVSNKT9XDTDYNJKJCPQMZCCOZVXMTXC</constant> </setHeader> <to uri="iota://fabryprog-iota?url=https://nodes.thetangle.org:443&tag=APACHECAMELIOTA&operation=sendTransfer&depth=3" /> </route>
