how can i run jersey 2.26 with JDK 1.7?

Question

I'm using JDK1.7 for my application.

I upgrade jersey 2.26 and now I am getting the error :

严重: Servlet [Jersey Web Application] in web application [/spcsis-1.0] threw load() exception

somebody can help me to do it?

Answer 1

From Jersey 2.26, all modules support only Java SE 8

See jersey dependencies:

Until version 2.6, Jersey was compiled with Java SE 6. This has changed in Jersey 2.7.

Up to version 2.25.x almost all Jersey components are compiled with Java SE 7 target. It means, that you will need at least Java SE 7 to be able to compile and run your application that is using latest Jersey. Only core-common and core-client modules are still compiled with Java class version runnable with Java SE 6.

Since Jersey 2.26, all modules are build using Java SE 8 and there is no support for running it on older Java SE distributions.

Answer 2

You have to use Jersey up to the 2.13, this is the last version which has been compiled by the JDK 1.7 (please look at the MANIFEST inside the JAR).

Answer 3

Your only option would be to rebuild jersey using Java 7.
