Java 升级到jdk7后DbVisualizer 6 启动空指针的处理方案

将JDK从6升级到了7,以前一直都死使用DbVisualizer 7来作为数据库的管理工具,可是自从升级完之后,每当启动DbVisualizer 7的时候都会报空指针异常,当时怀疑是ＪＤＫ版本的问题，可是将JAVA_HOME改回去还是没用,在网上搜索了一堆的解决方案,终于在官网上找到了相关的方案,如下:

 

1. In the DbVisualizer installation directory there is a .install4jdirectory.
2. In this directory create a file named pref_jre.cfg if it doesn't already exist.
3. Open the file in a text editor
4. Add the complete path to the root directory for the Java installation you want to use.
   Example: C:\Program Files\Java\jre6.
