compiling with non-standard classes

I am trying to compile a program using jar files that are not a part of Java 1.4 But for some reason, I'm getting errors when I try to specify the classpath. Can someone give me some help? What is the exact syntax? BTW, the classes I want to compile with are the JAXB classes. I am sure I did it right, but still can't compile.

The exact syntax is platform and implementation specific, actually, so you'd have to give a bit more info. In general, for Sun's implementations, it looks like
javac -classpath c:\dir\jar1.jar;c:\otherdir\jar2.jar MyClass.java
on Windows; on UNIX-like systems, which use semicolons properly as statement terminators, it looks like
javac -classpath /home/me/dir/jar1.jar:/home/me/otherdir/jar2.jar MyClass.java
There are other subtleties; you might show us what you tried and what errors you got.

Well I wouldn't be too sure of that under tha circumstances.
There's more than one way to do this. You can set the system CLASSPATH in the OS, or you can use the -cp (-classpath) option on both javac and java commands. (Or you can use an IDE which does this for you behind the scenes.)
The simplest syntax is something like:
javac -cp /foo/bar/myjar.jar MyClass.java
Perhaps it would help to know what happens for you now. What command are you using to compile? What error message do you get?

I'm following Sun's tutorial on running JAXB, and using their examples. The directions are listed at http://java.sun.com/webservices/docs/1.3/tutorial/doc/index.html under the "Configuring and Running the Examples Manually" section.
JAVA_HOME is set to my java directory, c:\j2sdk1.4.2\
JWSDP_HOME is set to my web servcies directory, c:\jwsdp-1.3\
I successfully ran the xjc batch file to create classes from the sample xml schema.
Then I tried to compile the Main java file and got the errors.
Here is the command line:
%JAVA_HOME%\bin\javac Main.java primer\po\*.java primer\po\impl\*.java

Here is one of the 100 error messages I get:

It can't find the JAXB classes .
So I changed the command line to list all the jar files in the C:\jwsdp-1.3\jaxb\lib directory.
Here was my new command line:
%JAVA_HOME%\bin\javac -classpath C:\jwsdp-1.3\jaxb\lib\jaxb-api.jar;C:\jwsdp-1.3\jaxb\lib\jaxb-impl.jar;
C:\jwsdp-1.3\jaxb\lib\jaxb-libs.jar;C:\jwsdp-1.3\jaxb\lib\jaxb-xjc.jar Main.java primer\po\*.java primer\po\impl\*.java
But still I get all the error messages.
Here is one of the error messages:

What can I do?
