Actually i did not faced this problem now.But have a doubt.
I compiled my code using java 1.6
and i deployed that in tomcat server ,in that java is configured of version 1.6.Then i changed the java version to 1.7
or to some other latest version.
Then is there any problem with .class files which are created using 1.6 compiler.
If any problems happen.How i can overcome those problems?
Thanks in advance..
