I was using Netbeans 6.8 with jdk1.6. But recently i had to uninstall jdk 1.6 and installed jdk 1.7. After that Netbeans stopped working even though the jdk location set in the netbeans.conf file. Now I unstalled both jdk and Netbeans and installed Jdk 1.7 with Netbeans 7.2. But the projects with swing frame work that I used in Netbeans 6.8 are not working here. It is showing the error message that Netbeasn 7.2 stopped supporting swing framework. What can I do to execute my projects since it is very much important for me. I tried to install swing framework plugin . But it is showing error. Should a system restore to an earlier stage before uninstalling will help to get back the working projects with netbeans 6.8 and jdk 1.6?
