This question is probably best asked on Stack Overflow as more Java experts will see it there.

Without knowledge of the changes you are making (or why) it is difficult to provide a definitive answer. The first question would be does the unmodified jar run with different versions of the JDK?

Also what is the error you are receiving and what Java servlet/application server are you running it in (Tomcat, JBoss, Websphere, etc)?

If the unmodified jar runs on the different versions then the source of your problem probably lies in the changes you are making. In theory you should not have any issues running the jar with JDK1.6.0_14 and 1.6.0_18.

My simple question is why jar building with jdk1.6.0_14 is work and bulding jar with jdk1.5 or jdk1.6.0_18 is not work???

My soruce code contain.... + Struts: Adito's user interface is built using the Struts framework (1.2.8) ( + Jetty: Jetty (5.0) This provides the web server in the default server implementation. + HSQLDB: HSQLDB (1.8.0) Provides SQL based storage for Adito's configuration. + jcifs: JCIFS (1.2.13) is an Open Source client library that implements the CIFS/SMB networking protocol in 100% Java. CIFS is the standard file sharing protocol on the Microsoft Windows platform (e.g. Map Network Drive ...)

SOLVED: there is no restriction of jdk's version... it will work with all jdk version. – sahil Mar 29 '10 at 6:40
