web services without wsdl but pure java class
Hi all,
there is a manner to invoke a simple java class as a web service?
for example..if i have to invoke complex web services with a lot of parameters (objects, complex types) it's hard to do it with bpel (it is an hard work, need a lot of variables and variables initialization is hard): need only a simple class that invoke a web service with the correct parameters; so the bpel process need only to invoke this class passing only parameters as string or simple elements types or just nothing (i mean during bpel invoking call (<invoke>))..
thanks
Roby

Also if you feel that the data manipulation mechanisms provided by BPEL is
not enough, you can use E4x extensions for data manipulation.
Thanks

I think you meant xslt.
It's also convenient to use xquery as expressionLanguage. It looks for
example like this:
<doc>
<a> {$var} </a>
<b> {$var2} </b>
</doc>
But as for complex invocations, it's not a good idea to pass a lot of
data between web services. You can consider using external variables
to store this info in database (for example in id, blob rows) and pass
only ids.

Bpel is for web services, so you cant invoke anything without
wsdl. In my practice, it is easer to do complex initialization of
variables using xst instead of multiple copy statements.
