[转]Access restriction:The type JPEGCodec is not accessible due to restriction on

Access restriction:The type JPEGCodec is not accessible due to restriction on required library C:\Program Files\Java\jre6\lib\rt.jar


解决方法：
Project -> Properties -> libraries，
先remove掉JRE System Library，然后再Add Library重新加入。
============================================
在Eclipse中处理图片，需要引入两个包：
import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGImageEncoder;
报错:
Access restriction: The type JPEGImageEncoder is not accessible due to restriction on required library C:\Java\jre1.6.0_07\lib\rt.jar


此时解决办法：
Eclipse 默认把这些受访问限制的API设成了ERROR。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。
优先选择第一种方法
