[Jython-dev] Re: WEB-INF/classes & WEB-INF/lib/*.jar inaccessible in jython servlet

[Brian Z. <bri...@ya...>]

I figured it out. To answer myself:

    Currently in PyServlet.java, setting "python.home" in WEB-INF/web.xml
and the following code are MUTUALLY EXCLUSIVE!

"""
props.setProperty("python.home", rootPath + File.separator +
                                 "WEB-INF" + File.separator +
                                 "lib");

props.setProperty("python.packages.directories",
                  "java.ext.dirs,pyservlet.lib");
props.setProperty("pyservlet.lib",
                  rootPath + File.separator +
                  "WEB-INF" + File.separator +
                  "lib");

props.setProperty("python.packages.paths",
                  "java.class.path,sun.boot.class.path,"+
                  "pyservlet.classes");
props.setProperty("pyservlet.classes",
                  rootPath + File.separator +
                  "WEB-INF" + File.separator +
                  "classes");
"""

I kind of understand the reasoning behind this: make deployment
self-contained. But setting "python.home" to <context>/WEB-INF/lib really
makes development inconvenient (any module except sys need to be copied into
WEB-INF/lib).

Will it do any harm if we set pyservlet properties independent of
"python.home"?
