I'm using the Head First EJB book. I want to compile AdviceClient.java to access the AdviceBean. the jar file for the example can be found at
http://www.wickedlysmart.com/HeadFirst/HeadFirstEJB/HeadFirstEJBIndex.html
Can somebody tell why i'm getting the following error ?
********************************************************************
C:\projects\advice>javac -classpath {$CLASSPATH}:AdviceAppClient.jar AdviceClient.java
AdviceClient.java:4: package javax.ejb does not exist
import javax.ejb.*;
^
AdviceClient.java:5: package headfirst does not exist
import headfirst.*;
^
AdviceClient.java:25: cannot resolve symbol
symbol : class AdviceHome
location: class AdviceClient
AdviceHome home = (AdviceHome) PortableRemoteObject.narr
ow(o, AdviceHome.class);
^
AdviceClient.java:25: cannot resolve symbol
symbol : class AdviceHome
location: class AdviceClient
AdviceHome home = (AdviceHome) PortableRemoteObject.narr
ow(o, AdviceHome.class);

location: class AdviceClient
Advice advisor = home.create();
^

My classpath is set as followed:
c:\j2sdkee1.3.1\lib\j2ee.jar;
c:\j2sdkee1.3.1\lib\j2eetools.jar;
c:\j2sdkee1.3.1\lib\jhall.jar;
c:\j2sdkee1.3.1\lib\j2ee-ri-svc.jar;

Hi,
You're on a DOS/Windows system, therefore your CLASSPATH variable is incorrect.
It should be
%CLASSPATH%
and not
{$CLASSPATH} (even this is incorrect, probably a typo, should be ${CLASSPATH}).
Type
echo %CLASSPATH%
at the cmd prompt to see if you have it correctly set, and paste it here if you still have problems.
So, the DOS equivalent is something like:
javac -classpath %CLASSPATH%;AdviceAppClient.jar AdviceClient.java
(notice the ; after the CLASSPATH - another DOS change from UNIX).

Thanks for your response.
I'm still having the problem, but the message is different now.
***************************************************************************
C:\projects\advice>javac -classpath %CLASSPATH%;AdviceAppClient.jar AdviceClient

Hi,
put your -classpath around quotes...
-classpath "%CLASSPATH%;blah;blah;blah"
That should fix it right up! :-)
Hope that helps.
