AdviceAppClient.jar and AdviceClient.java compilation failure...again;-)

[Raul Vieira]

Hi everyone

I'm working through the Head First EJB (great book so far) and I've run into some trouble when trying to compile the AdviceClient.java. I know this is not the first time that this has been reported, but I've gone over all of the different postings without finding a resolution. I'm sure this is a environment variable issue, but I'm at a loss. Below is the contents of all the important stuff and the results of my compliation attempt. I'd appreciate any guidance that could be provided in solving this issue.

--ENVIRONMENT VARIABLES:

CLASSPATH = .;C:\j2sdk1.4.1_02\bin;C:\j2sdk1.4.1_02\lib;C:\j2sdkee1.3.1\bin;C:\j2sdkee1.3.1\lib\j2ee.jar

J2EE_CLASSPATH = C:\j2sdkee1.3.1\lib

J2EE_HOME = C:\j2sdkee1.3.1

PATH = .;C:\j2sdkee1.3.1\bin;C:\j2sdk1.4.1_02\bin

JAVA_HOME = C:\j2sdk1.4.1_02

You don't need any of the following on your classpath.

C:\j2sdk1.4.1_02\bin
C:\j2sdk1.4.1_02\lib
C:\j2sdkee1.3.1\bin

Try ...

CLASSPATH = C:\j2sdkee1.3.1\lib\j2ee.jar;.\classes

With this classpath you should not need to specify a classpath on the command line also. The AdviceAppClient.jar is also not needed, and in fact could cause problems. If anything you might put AdviceApp.jar (because it contains the headfirst package), but thats not needed as long as (1) the headfirst package is in your classes folder, (2) your classes folder is just off of your working folder (advidce) and (3) you compile from your working folder (advice). If you compile from your src folder, then use this instead ...

CLASSPATH = C:\j2sdkee1.3.1\lib\j2ee.jar;..\classes

If it still doesn't work then confirm that your headfirst package has all of the interfaces. They should all be there.

Hi Raul,

Are you sure that you've placed all the java source files and AdviceAppClient.jar inside a "headfirst" folder:

C:\Documents and Settings\Raul\My Documents\Development\SCBD Prep\projects\advice\headfirst\ 

And compile from

C:\Documents and Settings\Raul\My Documents\Development\SCBD Prep\projects\advice

folder using:

javac -classpath headfirst\AdviceAppClient.jar headfirst\AdviceClient.java

Guys if you want to get this compiled and get moving look no further than what Rob says! Very accurate and to the point...just try that out...trust me. I was also but now
