Message253

In my app I don't use CLASSPATH much 'cause it gonna be somewhat big (about 50 jars)
Instead of this I use wildcard as argument to my app-launcher, which parses wildcard and finds every jar i need (builds net of ClassLoaders etc.) and Class.forName("anyClass"); works just fine in any piece of app.

Jython package manager(SysPackageManager.java) uses "java.class.path" property alot when huntin' for jars.
In my app-launcher expand-java.class.path code was added
someth' like that 

String currPath =  System.getProperty("java.class.path");
String separator = ";";
currPath += separator + "myPackage.jar";
System.setProperty("java.class.path", currPath);

After that modification alot of 
*sys-package-mgr*: processing new(modified) jar, 'X:\a\b\c.jar'
was shown at the Jython initialization /Py.initPython();/ assuming everithing Ok.

BUT!
"from a.b.c.d import myClass" - ImportError: cannot import name myClass
"from a.b.c.d import *" - Ok
"dir()" - names of classes with myClass among... Hm?????
"d = new myClass()" -

When I put jar containing myClass.class in CLASSPATH explicitly - everithing perfect.

Try to put something like 

String currPath =  System.getProperty("java.class.path");
String separator = ";";
currPath += separator + "myPackage.jar";
System.setProperty("java.class.path", currPath);

at the beginning of org.python.util.jython and don't put myPackage.jar at CLASSPATH and HAVE FUN ;)
