Project development has always been adopted is jdk1.5, there is no problem. These two days, because a member is reflected in the installation of the relevant tools, the development of eclipse can not be opened, prompted the current Java version of 1.4, and the need for 1.5. by typing "java-version" in MS-DOS, the version of Java is indeed 1.4. Look at the Java environment variable settings, and did not find the problem, path is pointing to the 1.5 version, Baisibuxie. After others remind, find the problem. The original run dry report in order to smooth the implementation of its procedures, forcibly put the installation file from the version of Java to point to write into the registration table. Damn it...
Therefore, enter "regedit" in "Run", open Registry Editor, and modify the required version path of the JDK under Hkey_local_machine\software\javasoft.
