Classpath error: packages using packages

Question

I'm getting an error while doing:
javac -classpath x.y.z x\y\z\*.java
---error message:
.\x\y\z\SubQueryHelper.java:159: cannot resolve symbol
symbol : variable ConvertSQL
location: class x.y.z.SubQueryHelper
java.sql.ResultSet resultSet = ConvertSQL.getResultSet(myTabResults);
^
---my classpath:
CLASSPATH=C:\;C:\WINNT;C:\WINNT\SYSTEM32;C:\j2sdk1.4.1_03;C;\j2sdk1.4.1_03;C:\j2sdk1.4.1_03\bin;C:\a\b\c;C:\a\b\c\easj2ee.jar;C:\a\b\c\x\y\z
I think I have the right dirs in the classpath, but I think I need to access other packages:
x\y\z uses x\y\a and x\y\b
Do I need to specify the other packages or does java look for them automatically? What am I missing?

Thanks limeybrit9 and jschell for the replies.
Thanks to both of you, I determined:
1. my classpath was okay
1b. I didn't need the C:\a\b\c\x\y\z (just C:\a\b\c).
1c. I could just use javac myFile.java (no -classpath)
Then I decided to look at import statements and make sure they were okay. Took a working package, added all import statements and got the same errors so the current import statements worked.
"When you have eliminated the impossible whatever remains, however improbable , must be the truth" -S.H.
Therefore;
'cannot resolve symbol' because I cut and pasted from another class and those variables weren't defined in the new class.
