Re: [Py4j-users] Py4j and error - "Trying to call a package"

[Barthelemy D. <ba...@cs...>]

Hi,

Sorry about the delay in responding and thanks for using Py4J!

The first line looks good except that you need to use the fully qualified name of the class containing the static method (unless the class is in the java.lang package).

For example:

lp = gateway.jvm.package1.package2.ConvertFunction.convert("")

The error you are seeing seems to point into that direction as well.
