运行SQL Developer时候出现java.lang.NoClassDefFoundError:com.sun.jdi.Bootstrap

我的电脑装的是Oracle 11g

因为要JDK的支持,java才能连接数据库,所以装了JDK1.7,请注意接下来的话:

装JDK时免不了要装jre,但是

    jdk和jre不能都安装在java文件夹的根目录下,jdk和jre安装在同一文件夹会出错;

装好Oracle,替换掉sqldeveloper,以为万事大吉的时候,意外发生了:

  打开Oracle里面的SQL developer出现了以下错误,但是顺利打开了,不爽

查来查去都没有解决~!后来发现其实挺简单的:在所有程序里有一个jre的程序:Java Runtime Environment

只要将jre那部分的程序卸载掉,就正常的跑起来了
