is not accessible due to restriction on required library rt.jar

问题:The type JPEGImageEncoder is not accessible due to restriction on required library C:\Java\jre1.6.0_07\lib\rt.jar

这个事eclipse的设置问题,它默认把这些受访问限制的API设成了ERROR,你只要把
Windows-Preferences-Java-Complicer-Errors/Warnings
里面的Deprecated and restricted API中的Forbidden references(access rules)选为Warning就可以编译通过了。
