java 找不到jar怎么办?找不到jar包的解决方法
1.右键项目-》属性-》Java bulid path-》jre System Library-》access rules-》resolution选择accessible,下面填上** 点击确定即可!!!
推荐教程:《java学习》
2.在MyEclipse中编写Java代码时,用到了某个jar,import sun.misc.BASE64Decoder.*;可是MyEclipse提示:
Access restriction: The type *Decoder is not accessible due to restriction on required library C:\Program files\java\jre7\lib\rt.jar Access restriction : The constructor *BASE64Decoder() is not accessible due to restriction on required library C:\Program files\java\jre7\lib\rt.jar
解决方案1:
只需要在project build path中先移除JRE System Library,再添加库JRE System Library,重新编译后就一切正常了。
解决方案2:
Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and trstricted API -> Forbidden reference (access rules): -> change to warning
