RE: True Dynamic Invocation of Web Services
I have managed to get a working soloution, and will be looking to put a
release together, can you tell me the current status of WSIF releases.
I had to modify the src to put in a fix as per the following thread
===
Hi JeroeN,
You are right.
We were also facing the same issue and we commented the check and went
ahead.
It is able to parse the schema elements now.
Regards
Prakash

Hi,
While trying to use this new version I run into a problem (which has
already been reported in JIRA: WSIF-75):
Parser.getTypesSchemas fails to find the schema in the wsdl types
because of the following code (lines 508-510):
Object nextEl = extEleIt.next();
if(!(nextEl instanceof UnknownExtensibilityElement)) {
continue;
}
nextEl is a SchemaImpl which is not an UnknownExtensibilityElement and
further processing is skipped. I believe this test can be safely removed
because a few lines below the nextEl type is checked again.
I'm running with the libraries from wsif-2.1.0_RC2.
Hope someone can fix this.
Greetings,
JeroeN

I would prefer a released version to use, as oppposed to personally
modified code.
Thank you for any assistance.

Try with XSUL Libraries, are advanced compared to WSIF.
Work out with the samples from XSUL, then you will get an idea how
different is it from WSIF.
Then proceed further...

Hi,
I am working on a project that wishes to create a mechanism for
calling
web services dynamically. It is envisaged that this calling will
be
controlled by the internal scripting language of the program,
therefore
no compile time knowledge of the web service will exist.
Our program is written in C++, but we are planning to use a
separate
Java program (comunicating via TCP/IP sockets) to call the web
services.
It is planned that the intercomunication will be in XML,
probably with
XMLBeans representation on the Java side.
Idealy what I would like to do is be able to pass XML fragments
directly
to the WSIF call engine and retrieve XML fragments back from the
responses. These could then be handled by our program and
translated
to/from the nescersary structures. As our calls will be
controlled by a
scripting language, we can assume that the users have a grasp of
the
correct parameters to pass to the webservices and will define a
way of
handling the incoming return values in an appropriate manner. We
will
probably add some additional type checking in as a separate
task,
therefore the WSIF component does not need to worry about this.
Currently I have got the examples simplesoap and complexsoap
running and
have created a test client that takes a wsdl & op name and
attempts to
map the inputs and outputs. I have managed to succesfully call a
webservice by providing an object to deserialize the return
message to.
But as stated above I would prefer to do this in a dynamic
fasion so
webservices can be chosen at runtime.
I have seen some posts making rough sugestions as to how to
configure
WSIF to operate dynamically, but none of this has given me a
concreate
starting point with which to pursue.
My understading is that I would need to write (de)serialisation
objects
and inform WSIF to use these. Is this a correct evaluation of
the way to
proceed? Can you point me in the right direction as to how to
write
these (de)serialization routines, and how to configure WSIF to
utilize
them?
I appreciate any help you can give me in this matter
