don't forget marketing, behold windows.
CORBA is complicated but its also more widely deployed in the enterprise
because this problem domain needs the additional feature set.
my comments regarding xml-rpc are targeted towards enterprise
implementations. if all you need is simple rpc, than xml-rpc will
provide 80% functionality of soap at 20% of the complexity (not my
numbers) and i recommend to anyone to use xml-rpc. but if you need
actual cross-platform object access/transport, than it just won't cut it
and then you need the additional functonality of soap.
also back to the marketing hype, if something isn't supported than it
tends to wither away into a niche. while xml-rpc is used in the trenches
for lots of stuff, SOAP is supported by lots of major software
developers (ibm and ms come to mind) and it will become the future
standard supported by interoable products (in many ways it already has).

implementing a standard and using a standard are different things. do
you need to understand how a db works to query it?
do you really need to understand how xmlrpc works when you do something
like this?
(pseudo-code)
xmlrpcServer('http://yourzopeserver.com')
print xmlrpcServer.objectIds()
i think that as long as the library implementors create a clean
interface to the system than the novice should be able to use the system
without as a blackbox.

i agree with /F description of SOAP, but i have a different guru.
Dave Winer is the/a writer of the specs for of XML-RPC and SOAP. a bit
dated link.

I agree that there is a place for both protocols, (right tool for the
right job), and that zope should support both. although how is another
can of worms, since i don't think people want the same xml-rpc style
automatic opening of your entire site that currently happens with zope.

Re: [Zope] Python and EJB (J2EE)
i've been playing around with servlets (tomcat, jserv, orionserver.com) and generally been pretty happy with them. development cycle is a lot slower than zope. i did some prelim work on hooking up jserv to zope but gave up cause the performance generally sucked (jserv is still using apj1.1 which doesn't have persistent connections) and figured there were easier ways to get the two talking besides directly ala distributed protocols or shared backend resource like a rdbms. j2ee is more than just ejbs, its a whole slew of technologies like (jdbc, jndi (directories), jms (messaging), jts (client transactions), jaxl?(xml)...). one advantage of using java for a project thats going to be talking several of these protocols is the fact that there is a standard supported library for it as opposed to python's bazaar style of development and support (not to mention documentation). integration of this stuff in python generally requires evalutation on a per protocol/library basis because in some cases the library just isn't robust enough to handle the work (python's soap support comes to mind). as for component technologies, i really feel this comes out more as a programming paradigm in python rather than a forced technology. as for distributed technologies, while xml-rpc is useful and simple its not useful (IMO) for enterprise programming, its too basic. it requires alot of custom app programming to transfer meaningful exceptions. some protocols/libraries that i would like to see in python would be soap, wddx (bindings for http&soap), uddi. i've never used com/dcom so i've nothing to say about them. python does have great corba support (omniorb, fnorb) and some is working on integrating zope as a corba system (hopefully they'll write up a howto/ release some code), and pyro can cut it for simple distributed systems. so what would you like to see in a python component container? kapil Hung Jung Lu wrote: > > Python and EJB (J2EE) > = > > Searching through comp.lang.python newsgroup archive > ([EMAIL PROTECTED]) and the [EMAIL PROTECTED] mailing list, I have not been > able to find much about EJB (Enterprise Java Bean) and Python/Zope > comparisons.

this probably isn't your problem, but in your above example getimages
looks like it should be getImages.
i'm not sure why you want work by hand on the xml-processing, since
xmlrpclib already exists. if you want to debug your setup you can use
shane hathaway's tcpwatch as a proxy which show you what goes out on
the wire.
as for the location of such code, it depends on what you're doing with
the results, i think the choices are between a product and an external
method.

Re: [Zope] Can Zope use a Different Python?
Hi i'm not sure exactly whats being asked here. zope on linux doesn't include its own python interpreter. you can choose which one executes zope and its external methods by specifing the interpreter binary in the start.py. its quite possible that your installing third party modules into the distros python in /usr/bin/python, in which case if zope's using /usr/local/bin/python you won't see them and you'll get import errors. if this is the case copying the third party modules into /usr/lib/python1.5/site-packages will solve the import errors, or moving the modules into the zope_dir/lib/python/ (or perhaps a subdirectory with an init) might do the trick. if you specifically want to run something through a custom python interp from zope you might need to use os.popen2 (or variant) in an external method, or setup sometype of interprocess communication via xml-rpc or an rdbms or shared file, etc. hope that helps kapil Gary Perez wrote: > > Hi. > > We've got Zope 2.2.2 installed on a Linux box.

if the xml format is simple you could just do it dtml, it would end up

Another method that should increase both speed and reliability is to directly inject the mail into a relay smtp server's mail queue. this is definitely mail server dependent but offers the greatest performance gains and is capable of scaling and greater reliabiltiy (dependent on mailserver). usings lists is a valid solution but it doesn't get at the core question of how to send more mail messages from zope quickly and reliably. cheers kapil ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

In python any object can be a container, the use of the ObjectManager

objects.

some more information on what you changed in the container would be
useful.

this pseudo code should give you the result you want?, it works for me
to display objects in the manage_main.
def manage_addMyContainer:
foo = MyContainer()
bar = MyObject()
foo._setObject(bar, 'bar')
self._setObject(foo, 'foo')
caveat, register your permissions properly on the manage_add, and note
that adding bar in this way will mean it won't have access to
acquisition properties from further up the tree at creation (including
manage_afterAdd).
also for registering manage options this syntax is a little more
inclusive.
manage_options=(
OFS.ObjectManager.ObjectManager.manage_options+
(
{'label':'YourTabHere', 'action':'YourMethodHere'},

AccessControl.Role.RoleManager.manage_options+

I use Zope 2.1.6 its probably a security error. you need to either enable subobject access or explicitly register the method as part of the products permissions. something like this allow_access_to_unprotected_subobjects=1 this is not the recommended way to it as you'll open up the entire product to access. buts it useful to identify if its a security issue. kapil > Thanks, Petr > -- > Petr Knápek > NEXTRA Czech Republic, s.r.o., Hlinky 114, 603 00 Brno, Czech Republic > e-mail: [EMAIL PROTECTED] > > ___ > Zope maillist - [EMAIL PROTECTED] > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Taco, i'm pretty sure your objectValues on the addressen folder to fill in to fill in the addresses of the artiklen document. zope renders these subtemplates slightly differently than a template called directly by the browser, when you're calling the addressen subobject from the document call it like this or in a if that doesn't solve it for you, than it would be helpful to have the relevant src of the document. i tried without success to duplicate the exact same error, but i'm pretty sure that the problem has something to do with this.

Re: [Zope] Want to access ZClass Instance from external program
Sorry Jon, i've lead you down a slippery slope...
unlike ttw dtml-methods and the rest of zope which relies on the
security context soley, for a filesys python method to be exposed
through the web via xml-rpc it must have a doc string as well as have
proper credentials.
looking through propertysheets there is no 'proper' way to do this...
but i lead you down the path, so here is a way back out...
there are a couple of options.
the easiest is to have dtml_method for this zclass that functions as a
helper method,
like
dtml method -- external_helper
and in the client
x = root.subfolder.zclass.external_helper()
meta_info=eval(x)
print meta_info
({'id': 'vvv', 'type': 'int', 'meta': {}, 'mode': 'w'}, {'id': 'aaa',
'type': 'lines', 'meta': {}, 'mode': 'w'}, {'id': '', 'type':
'tokens', 'meta': {}, 'mode': 'w'}, {'id': '122', 'type': 'date',
'meta': {}, 'mode': 'w'}, {'id': 'ff', 'type': 'float', 'meta': {},
'mode': 'w'}, {'id': '>>', 'type': 'text', 'meta': {}, 'mode': 'w'})
or if external_helper returned propertyItems()
[('vvv', 1), ('aaa', ['']), ('', ['ss', 'aa1113', '3', '4']),
('122', DateTime('1900/01/01')), ('ff', 455.0), ('>>', '')]
if you're working with DateTime values in your propertysheets this will
be trickier as you'll need to either retrieve the property you want
independently or import Zope's DateTime module. also remember to set the
security on the helper method so its not helping somebody hack your
site.
the rest of the ways are exercises in wasting time... IMO
hope that helps out
Cheers
