eclipse - Diamond operator(<>) not working in java 1.7

Question

I have the following error for compiling a jsp file:

'<>' operator is not allowed for source level below 1.7

I'm using jdk 1.7.x and eclipse Kepler Also I have set 1.7 as compliance level in project preferences in Eclipse, still the code is not working

Should I add any other config?

Answer 1

Check the following areas within Eclipse:

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
