编译jsp文件时出现以下错误:

源级别低于1.7的"<>"运算符不允许

我正在使用jdk 1.7.x和eclipse Kepler我1.7 as compliance level也在Eclipse中设置了项目首选项,但代码仍无效

我应该添加任何其他配置吗？

Answer 1

检查Eclipse中的以下区域:

1. Right Click Project > Properties > Project Facets > Java > Version 1.7

2. Right Click Project > Properties > Java Build Path > Libraries > JRE Library should be 1.7

3. Right Click Project > Properties > Java Compiler > Compiler compliance level

4. Window > Preferences > Server > Runtime Environment > Select the Server > Edit > Ensure JRE is set to 1.7
