Problem with starting Eclipse

I just downloaded Eclipse, unzipped the files and clicked the .exe file. I got the splash screen, then an error message which refered me to logfile. Two exceptions on it are:

java.lang.ClassNotFoundException: javax.xml.parsers.SAXParserFactory and
java.lang.NoClassDefFoundError: org/xml/sax/helpers/DefaultHandler

Any help will be appreciated.

You're trying to run Eclipse 3.x using JDK 1.3. It requires 1.4, even though the FAQ doesn't say so. Eclipse ought to check for this as soon as it starts up, but it doesn't seem to.

Anyway, make sure that "java" from JDK (or JRE) 1.4.x is the first one on your path.

Thanks for the quick reply.

I have j2sdk1.4.2_07 as my JAVA_HOME and my classpath is set like:

.;C:\j2sdk1.4.2_07\bin;C:\j2sdk1.4.2_07\jre\bin;C:\j2sdk1.4.2_07\lib;C:\j2sdk1.4.2_07\lib\tools.jar;C:\j2sdk1.4.2_07\jre\lib;C:\j2sdk1.4.2_07\jre\lib\rt.jar

The JDK in my Eclipse 8.1 is j2sdk1.4.1_05.

Are those two different versions of JDK going to make the Eclipse confused and fail to perform as it is supposed to?

Daniel,
Eclipse will just use the first one it finds. Since they are both 1.4 versions, you should be fine.

This does introduce the question of why you need/want to versions of 1.4 on your classpath. An application will only find one so the other is just taking up space. Might be time to do a little clean up.

The Eclipse 8.1 that I have comes with its own version of JDK, which is j2sdk1.4.1_05.

I already have a JDK in my machine. The JDK is j2sdk1.4.2_07.

Daniel,
Eclipse comes with an embedded JDK (used for auto-complete) which is in the Eclipse directory. The JRE/JDK used to run Eclipse itself can be changed.
