You're using --use_full_names, thus to access the wrapper for com.lchclearnet.swapclear.smart.SMARTClientDataProviderFactory you need to say: >>> from com.lchclearnet.swapclear.smart import SMARTClientDataProviderFactory Andi.. > > If I use --jar option I will still get the "AttributeError: 'bool' object has > no attribute 'setdefault'" error. > > Thanks, > > Chee Yong > > Chee Yong Teh > 27 Bush Lane, London, EC4R 0AN | +44 203 929 3138 > <image940421.png> > OTC Infrastructure Service of the Year & Global Compression Service of the > Year > -----Original Message----- > From: Andi Vajda <va...@apache.org> > Sent: 05 May 2020 23:30 > To: Chee Yong Teh <cheeyong....@quantile.com> > Cc: pylucene-dev@lucene.apache.org > Subject: Re: AttributeError: 'bool' object has no attribute 'setdefault' > > > On Tue, 5 May 2020, Chee Yong Teh wrote: > > > Hi Andi, > > > > That’s third party library jar file that we try to wrap so we can call it > > from python. > > > > I don’t really know why they create a classes like that way. > > > > Would you able to add an option to just only wrap classes under a > > package like I want to wrap all public classes in package > > com.lchclearnet.* > > > > So any public classes under com.lchclearnet.swapclear and > > com.lchclearnet.common will get wrapped?
