In case if java 8 is not compatible with spring anymore and we cannot download java 7 now. so how can we integrate our application with java.

please help

The exception states "[...] are only available on JDK 1.5 and higher". What makes you think using java8 breaks anything here? — f1sh, Aug 06 '17 at 11:23

The weird thing is that he have already use Sping `4.0.6.RELEASE`, while Spring has Java 8 support since `4.0.3`. https://spring.io/blog/2014/03/27/spring-framework-4-0-3-released-with-java-8-support-now-production-ready — Duong Nguyen, Aug 06 '17 at 11:33

Spring 3.x versions support up to Java 7 only. If you want to move onto the JDK8 you should use Spring 4+.

I think there is something wrong with your tool chain. You can troubleshoot the problem by taking the following steps

Make sure that:

you're using JDK 8 for compiling your source code. You can check it out with $ java -version
your maven is told to compile the source code with the right compilation level. I see that you're using the maven compile plugin which is configured to compile the target compilation level "1.6".
the Maven adds the right version of the Spring libraries. It might happen that you have still some transient dependencies of the old Spring version in your classpath. You can see which dependencies the project will fetch by giving $ mvn dependency:tree

By the way, the Spring Framework will attempt to find out the JDK version while executing some internal methods. If the JDK version resolved is not listed in the supported JDK versions, it will default to the Java 1.4 so it is why we see here that "expected version must be greater than JDK 1.5" in the exception's message. It might be that you still have some older versions of the Spring in your classpath - either coming along with your servlet container e.g Tomcat or as transient.

Hope it helps.

It seems that you are having issues with your spring.xml. You are trying to use
context: component-scan packages=""
Please ensure that you have used latest spring xsd's in your schema definitions and give a try. Please let me know if you are using annotations. I am having Spring 4.3.0 and Java 8 working perfectly fine. I have worked with Spring 4.1.3 and java 8 as well and It worked like champ. Let me know if you have any questions.
