[Jython-users] coercion error

[Andres Corrada-E. <co...@ci...>]

Hello,

I'm trying to set-up Jython to use the XML functionality in jaxp.jar and
parser.jar. The code fails with an error of the form:

TypeError: parse(): 1st arg can't be coerced to java.io.File,
org.xml.sax.InputSource, java.io.InputStream or String

The code is as follows:

    # Create new SAXParser
    factory = SAXParserFactory.newInstance()
    saxParser = factory.newSAXParser()

    # Create new handler
    handler = BookLibrary()

    # The test file to parse
    file = java.io.File('./books.xml')

    saxParser.parse( file, handler)

It seems that "parse" is being fed the class instance first, but I cannot
figure out how to do the call properly. Similar code works within Java
code, so I know classes are being recognized and have the required
methods.

Any clue what I'm doing wrong? Thank you.
