Troubles with my classpath

Hi,

I've read a lot of threads about the classpath, but I didn't really find
what I was looking for.
Briefly explained : i want to add jdbcdrv.zip to my classpath.
the file is located under: C:\Program Files\Sybase\SQL Anywhere 7\java

so i add to my classpath the directory with the zipfile, but i still can't
import anything from whitin that zipfile.

My classpath :
C:\Program Files\Java\jdk1.5.0_02\bin;C:\Program Files\Sybase\Jaguar CTS
3.5\html\classes;C:\Program Files\Sybase\Jaguar CTS 3.5\java\classes;C:\
Program Files\Sybase\Shared\Sun\jdk118\lib\classes.zip;C:\Program Files\
Sybase\Shared\PowerBuilder\classes.zip;.;%J2EE_HOME%\lib\j2ee.jar;%
J2EE_HOME%\lib\locale;C:\Program Files\Sybase\SQL Anywhere 7\jConnect\
classes;C:\Program Files\Sybase\SQL Anywhere 7\java\jdbcdrv.zip;

OS : windows XP

Structure of jdbcdrv.zip : /com/sybase/jdbc/..

When i want to import, i type
import com.sybase.jdbc.*;

And then i always get the error message : The import com.sybase cannot be
resolved.

I use eclipse to develop.

Does anyone has an idea how i can solve this problem ?

Thanks in advance,
Greetz,
Tom

I am new to using Eclipse, but whenever I need to add an external jar
file (or zip in this case) I usually do the following:

(This is version 3.0, btw)

1. In the Package Explorer, right click on the project name
2. From the context menu, choose Properties
3. Select the Java Build Path in the left pane
4. Click the "Add External Jars" button
5. Navigate to where the jdbcdrv.zip file is located and double-click
it. At this point it should add the zip to the build path
6. In the Properties dialog, select the Ok button.

Now go back to the editor window and hopefully your errors disappear -
btw, you may have to do a little editing and saving to cause Eclipse to
reparse the file (like press the space bar or remove whitespace, etc),

This works !!!

So if i get this right... Eclipse uses his own classpath, above that of the
one of the operating system?

Anyway...
A very big thank you man !

Yep, I don't even think it touches the OS classpath environment
variable. By the way, the steps above are for an individual project
classpath, but I think if you goto Window->Properties->Java->Build
Path->Classpath Variables you can modify the Eclipse environment
classpath, but I haven't tried that yet.

No problem, glad to help.

The path to your file has spaces in it, java doesn't like that. You could
move it or if you're using an IDE, add it as an "external library" through
that, it'll probably resolve the spaces problem for you.

i thought that already that those spaces were the problem, but even when i
put my library in another directory it wasn't working.
When i did your second thing, it worked... I imported the "external"
library and everything went fine.

Thanks to both of you!
