Subclassing/Inheriting in Inline::Java

[Jay Strauss]

Hi,

I'm trying to build a callback based on some java code.  Below is how I did 
it.  All the classes live in ~/IBJts/java/com/ib/client so I did:
export CLASSPATH=~/IBJts/java/com/ib/client:/home/jstrauss/java

But I'm getting errors:

[EMAIL PROTECTED]:~/bin$ ./callback                                             
  
A problem was encountered while attempting to compile and install your Inline
Java code. The command that failed was:
  "/usr/lib/j2sdk1.5-sun/bin/javac" -deprecation  -d 
"/home/jstrauss/bin/_Inline/lib/auto/Callback_6d40" Callback_6d40.java > 
cmd.out 2>&1

The build directory was:
/home/jstrauss/bin/_Inline/build/Callback_6d40

The error message was:
Callback_6d40.java:24: class EWrapper is public, should be declared in a file 
named EWrapper.java
public interface EWrapper {
       ^
Callback_6d40.java:34: cannot find symbol
symbol  : class Contract
location: interface com.ib.client.EWrapper
    void openOrder( int orderId, Contract contract, Order order);
                                 ^
...


I'm sort of stuck, I'm not real familiar with Java, so I'm not sure if this is 
a java environment config error or more on the Inline side of things.

Any help would be appreciated
Thanks
Jay
