A few days ago, I downloaded the latest version of Eclipse 3.0, unzipped into the E: / TEMP / Eclipse directory, pop up a small prompt box when starting, seeing an error in Eclipse / Configuration / next *******. Log Document. The file said:!

Although there are several doubts, the process of solving this problem is written out with the remaining doubts.
Problem resolution:
The cause of the problem is that the virtual machine found by Eclipse is 1.3.1_01 version, and this version of JVM does not bring a class such as javax.xml.parsers.saxparserfactory.
I guess the Eclipse.exe and% java_home% / bin / java.exe in the root directory, which is the JVM that is positioned to run.
Search JVM in order, Java.exe, based on
1 Does it have JRE in your current directory (originally said that this statement is not accurate enough)
2 Does it have JRE in the parent directory?
3 Query registry (HKEY_LOCAL_MACHINE / SOFTWARE / Javasoft / Java Runtime Environmet /)
So I copied the files in the entire Eclipse directory to my% java_home% / directory, follow the saying, it will go to find% java_home% / jre to find the virtual machine under this directory, and this virtual The machine is 1.5, so that Eclipse can start normally.
doubt
The original Eclipse found JVM1.3.1_01 is the first JRE I installed the post-installation of the operating system, located in C: / Program files / IBM / JRE / 1.1 / BIN and this JRE is not registered in the registry Follow
