Hi Patrick,

I’ve got multiple 11g instances on a single server, how can I setup/access a specific native 11g Apex environment (not using Apache) hosted on the different 11g databases?

Thanks

Hi Patrick,

I want to call the webservice through PL/SQL . I have XE database.I am using APEX . Want to implement the Single sign on concept(no need to login) from the system. It’ll go directly call webservice for login/pwd information(system user/pwd) and redirect to the requested page in the oracle apex application.
Any Idea?
Please let me know. how to do that? Becoz in XE database there is no package called UTIL_HTTP and UTIL_DBWS.

Thanks
Rahul Bhandari

I hope they get it better documented then the UTL_DBWS package.
UTL_DBWS looks nice out of the box, still works good with very easy webservices, but might make you unhappy when using webservices with more complex requirement,s e.g. multiple parameters, …
Furthermore utl_dbws still needs loading additional java-code using loadjava.
Best regards,
Martin

Doug,

thanks for the additional info how easy it is to make it available from a person who already tried it!

Thanks

Pawel,

you can consume web services in PL/SQL in different ways. Have a look at the JPublisher tool or the UTL_DBWS package. But you can also use UTL_HTTP or Oracle APEX to consume the web service.

Pawel,

It uses the XML DB protocol server to publish the web services.

Stored procedures are exposed via a URL that includes the schema name and the name of the procedure, similar to the way the DBUriServlet works in 10g. http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb15dbu.htm#sthref1957

This looks very promising to me.
Does user has ability to set name of such web service? I mean: How it will be visible for external consumers?
How about utilizing external web services within PL/SQL?

Patrick,

Native Database Web Services is the feature I was invited into the 11g beta program to test.

It works the way you described it. The only thing you have to do is grant execute on your procedure to a role, and it becomes available as a web service.

You can also have it execute select statements - with bind variables. That's a bit more complicated to use.

I'm not a web services expert, but I was able to call the web services from JDeveloper, Visual Studio, and other environments.

It's another nice feature for people who like to do everything inside the database.

Hi Patrick,

That is a cool feature. I hadn't seen that yet.

Just another month (hopefully) and we'll get our hands on the new version.
