标题[问题] 关於J2SDK 1.5.0 跟 JBuilder X
时间Wed Jul 19 10:18:00 2006
我原本使用jdk1.4.2
现在要改成jdk1.5.0
我已装好jdk1.5.0
然後open JubilderX欲进行以下设定
---------------------------------------------
1.Tools->Configure->JDKs，要把JDK5.0加进去。
2.Project->Project Properties->Paths-JDKs
选刚刚加入的JDK5.0
3.Project->Project Properties->Build-Java。
Language features设Java 2 SDK, v5.0 (generics enabled)
4.Project->Project Properties->Build-Java。
Target VM设Java 2 SDK, v5.0 and later
---------------------------------------------
以上步骤1、2我都setting好了
但是步骤3中，我的JbilderX并没有Language features这个项目
步骤4中，Target VM的下拉选单中最多只到Java 2 SDK, v1.4.0 and later
并没有Java 2 SDK, v5.0 and later
请问那位大大知道为什麽吗？
因为酱子设定没有完整
导致在compiler时会产生以下exception
"charAT.java": cannot access java.lang.Object,bad class file: C:\Java\jdk1.5.0\jre\lib\rt.jar\java\lang\Object.class,class file has wrong version 49.0,
should be 48.0,Please remove or make sure it appears in the correct
subdirectory of the classpath. at line 17, column 27"
thanks~
