[Jython-users] Jython pyDictionary to Java HashMap conversion

[Si C. <sc...@gr...>]

Hello.  I have to return a java.util.Hashmap from my jython code, and I 
just realized that it is not an automatic conversion.  For example,

 >>> pyMap = {"a":1,"b":2,"c":3}
 >>> pyMap.__class__
<jclass org.python.core.Pydictionary at ....>
 >>> from java.util import Hashmap
 >>> jMap = HashMap(pyMap)
TypeError: java.util.HashMap(): 1st arg can't be coerced into int or 
java.util.Map

I have not tried lists or arrays.  Is there a way to automatically 
convert these back to java equivalents, or must I use the Java 
constructors and write Java code to have them properly returned as Java 
classes?

Thanks in advance,

Si Chen
