The following is taken from: http://blog.itpub.net/post/325/1535
-------------------------------------------------- --------
The error log is recorded as follows:
eclipse.buildId = I200405211200java.version = 1.3.1_13java.vendor = Sun Microsystems Inc.BootLoader constants: OS = win32, ARCH = x86, WS = win32, NL = zh_CNjava.lang.ClassNotFoundException: javax.xml.parsers.SAXParserFactory at java .NET.URLCLASSLOADER $ 1.Run (unknown Source)
Take a closer look at the Java version, it is actually very simple.
3.0 Eclipse's JDK version is relatively high, how can I get 1.4 or more :-)
After changing a 1.5, it is OK. -------------------------------------------------- -----------------Why does this happen? I recalled the process of this error, because I have installed Oracle 9.2.0.1, as a result, the JRE in the system environment becomes the JDK 1.3.1 of Oracle. So the above situation has occurred.
