Issues with running weaved code.

[ChromoX]

When trying to run weaved code I get these error messages:


java -cp ../lib/kilim.jar:../lib/OAPI.jar:./ cayman.Main
Exception in thread "main" java.lang.Error: Unresolved compilation
problems:
Color cannot be resolved to a type
Color cannot be resolved to a type
Color cannot be resolved to a type
Color cannot be resolved to a type
Bar cannot be resolved to a type
Color cannot be resolved to a type
Color cannot be resolved to a type
at cayman.Main.main(Main.java:59)

Whats going on?

Actually I got that fixed... Now I have this problem while trying to
weave....

The command line I use to weave is below and the error it outputs is
below.

Thanks.

I posted an approach for weaving a few weeks ago. Did you try this? I want to know if this is a different kind of problem or has an existing solution.

Here is the solution again: 

Don't overwrite the original class directory or files. 

Have two separate directories, one for the original and one for the  
woven classes 
Say your classes are in  "./classes". Your development is done as  
follows
      1. javac -cp ./classes -d ./classes src/*.java  #      Put ./
classes in classpath, and compile into ./classes
      2. Weave classes into ./wclasses
         j   ava -cp ./classes -d kilim.tools.Weaver -d ./wclasses  
classes

For running the program, put both ./wclasses and ./classes in the  
classpath, _ahead_ of ./classes
      java -cp./wclasses:./classes Main

That way, while developing, you are only coding against the original  
classes.
While executing, you are coding against a mix of  woven and original  
classes, except that it prefers the woven version if one exists.
