Hi,

Can we use the DMN Engine with a Java 1.6 project?

Thanks,
Samar

@Samarjit_Uppal yes you can use. Before that make sure are you using compatible versions. You can check these version compatibility between Java<>spring boot starters<>camunda bpm

By default, Spring Boot 1.4.1.RELEASE requires Java 7 and Spring Framework 4.3.3.RELEASE or above. You can use Spring Boot with Java 6 with some additional configuration

Thanks Aravind, but we are not using Spring. Here is my pom file, its using dmn version 7.10.0 Do i need to switch this to a lower version for java 1.6 compatibility? :

4.0.0

Found the fix. Upto 7.9.0 is compatible with java 1.6

camunda-engine-dmn 7.10.x requires Java7+

6

Camunda 7.10 supports Java 7+
