This problem has been flexed that I have been in a good day, I have always thought about how. I use the operating system is Windows 2000 Professional. I originally installed J2SDK1.4.2_07 on the machine, set Java_Home = C: / Program Files / Java / J2SDK1.4.2_07Path = C: / Program Files / Java / J2SDK1.4.2_07 In CMD Java -Version, everything told me that J2SDK 1.4.2_07 strange things happened when installing JDK1.5.0_01, after installation, did not configure any java_home parameters and path parameters. In CMD Java -Version, tell me the current version of J2SDK1.5.0_01. I started to automatically add relevant PATH and other parameters in the system variable as it would want Oracle, but I didn't find it carefully. I want the default java_home in the system to use J2SDK1.4.2, J2SDK1.5.0 just want to do some tests in Eclipse 3.1m4, how should I configure it? ! Does anyone have encountered this problem? !

I want to make a nourishment of Jin Jinmei, and I will set it from the fire; thinking that I think the taste of the sky, I need to go to the thin ice. The sky will drop the big and the people, and must first bitter their minds, work their bones, hungry their skin, when they are marked, and the line is, so it is moving, gain it. We grow neither better Nor Worse As We result.

PATH = C: / Program files / java / j2sdk1.4.2_07? ? ? Should be added with bin.

Well, I also have the same trouble, the company's products should be based on 1.4 development, I want to try 1.5. However, Primejava mentioned the article written very well, the problem is basically solved, and can be changed by reacting Path. It is still a problem with Applet Runtime.

The bin of PATH is added, the front is negligent, not written. Ok, basically get it, but there is still a small problem, let me write. When you are installing 1.5.0 J2SDK, if you choose public JRE, he will replace the original 1.4.2_07 public JRE, you can see it in the registry. -------------------------------------------------- ------------------------------------ HKEY_LOCAL_MACHINE / SOFTWARE / JAVASOFT / JAVA RUNTIME Environment value is 1.5 - -------------------------------------------------- ---------------------------------- If you change it into 1.4.2_07 (and put all the corresponding parameters It is changed to 1.4.2_07), will be reported as follows: ------------------------------------ -------------------------------------------------- Has Value '1.4', But '1.5' Is Required -------------------------------------- ----------------------------------------------- but resolved The method is also very simple, only one J2SDK 1.4.2_07 PUBLIC JRE is installed, J2SDK 1.5.0_01 does not install public JRE. Deploy two Eclipse, Eclipse 3.0.1 JRE path points to JRE of J2SDK 1.4.2_07, Eclipse 3.1m4 JRE path points to J2SDK 1.5.0_01 / jre is OK.
