          Is error occurs only calling through VDB or do you get results when executed through say a web browser?

          • 2. Re: calling servlet ( web service) through Teiid desinger gives error
            Amit Agrawal Newbie

            This error occurs when I execute query through VDB. I get the below xml response when executing the ULR thurough Web browser. is that what you were asking?

              Ramesh Reddy Master

              Ok, now how are you calling it in the VDB? in a transformation? can you post the SQL you wrote? I would need Designer project to open your VDB and see the query.

              • 4. Re: calling servlet ( web service) through Teiid desinger gives error
                Amit Agrawal Newbie

                I wrote below query in transformation editor. once the VDB is created, I deployed it on seriver and finally executed select * from MyCustomers from Squirrel. I am also attaching my workspace.

                 

                 

                SELECT

                MyCustomers.ID, MyCustomers.Name, MyCustomers.ContactFirstName, MyCustomers.ContactLastName, MyCustomers.Phone, MyCustomers.Address, MyCustomers.Address2, MyCustomers.City, MyCustomers.State, MyCustomers.PostalCode, MyCustomers.Country, MyCustomers.CreditLimit

                 

                FROM

                (

                EXEC mywebsource.invoke(binding => 'HTTP', action => 'GET', endpoint => 'http://localhost:8080/WebServiceSource/SampleServlet')) AS ws, XMLTABLE('/customers/customer' PASSING ws.result COLUMNS ID integer PATH './customernumber', Name string PATH './customername', ContactFirstName string PATH './contactfirstname', ContactLastName string PATH './contactlastname', Phone string PATH './phone', Address string PATH './addressline1', Address2 string PATH './addressline2', City string PATH './city', State string PATH './state', PostalCode string PATH './postalcode', Country string PATH './country', CreditLimit bigdecimal PATH './creditlimit') AS

                MyCustomers

                  Ramesh Reddy Master

                  Now, when you issue the query through the SquirreL you will see the above exception right? Also, what vesion of Teiid are you using, try using Teiid 8.4.final and Teiid Designer 8.2 Alpha.

                  • 6. Re: calling servlet ( web service) through Teiid desinger gives error
                    Amit Agrawal Newbie

                    yes, I get the above excpetion while executing the query (select * from MyCustomers) from Squirrel.

                     

                    I am using below version of teiid.

                     

                    Teiid : teiid-8.2.0.Final

                    Teiid Designer : 8.0.0.Final

                    jboss-as-7.1.1.Final

                     

                    do you think this issue is  because of the older version of Teiid? can you also let me know if installing the versions you suggested would solve the issue?

                      I tried the query after installing Teiid 8.4.final ,Teiid Designer 8.2 Alpha and Jboss jboss-eap-6.1.0.Alpha but now getting below error.

                        You got me thinking, but as I was trying it out, I realized that for REST type calls you need to use "invokeHttp" not "invoke". "invoke" is for the SOAP based calls. That may be reason your 8.2 did not work either.

                          HI Ramesh,

                           

                          Thanks for the reply. I was able to get it worked by using invokeHttp. can you point me to any docuemnt about passing http headers to the web service? I can send the reqeust using reqeust parameter but could find any document on sending headers ( specifically I want to send sm_user ( siteminder user header) to web service?)

                           

                          Thanks,

                          Amit

                            Amit,

                             

                            There is no built in way to do that from Teiid SQL language.

                             

                            Teiid 8.4 uses CXF underneath for all the HTTP communication. So you configure CXF for additional stuff. See https://docs.jboss.org/author/display/TEIID/Web+Service+Data+Sources especially 'Configuring SSL Support". Now, I searched for adding the custom headers in the CXF only found http://stackoverflow.com/questions/10479396/apache-cxf-set-http-header which you have to write a interceptor for. I am not sure if there any pre-built interceptor already available for htto-conduit to set the custom headers. Here is another CXF link where they mention different kind of authentications http://cxf.apache.org/docs/client-http-transport-including-ssl-support.html that may be useful.

                             

                            If you do write the interceptor, you need to include the jar file in "jboss-eap-6.1/modules/system/layers/base/org/jboss/teiid/resource-adapter/webservice/main" directory and modify the "module.xml" to include it. If you do find another solution please let us know about it for other users.

                              It seems like for the invokeHttp case we could easily offer the ability to specify headers as the execution logic already supports custom header properties for odata usage.  We would just have to decide on an appropriate calling structure as we don't have something resembling a map (such as a varag string parameter that we process in pairs).

                                Hi Ramesh,

                                 

                                As I mentioned, I was able to get the servlet worked in 7.1.1 and teiid 8.2.  we are now wokring on creating a custom interceptor to pass the HTTP headers. can you let me know the corrosponding path in 7.1.1 where we have to copy the jar file and location of modules.xml file? Also, what will be the entry in the modules.xml so our own custom interceptor code gets invoked?

                                  Amit,

                                   

                                  In Teiid 8.2, the resource-adapters were deployed as RAR files, in 8.4 version they are being deployed as modules. So, it is easy to do in Teiid 8.4. In Teiid 8.2, you can create a new module, or copy it in "modules/org/jboss/teiid/translator/ws/main" directory, and the entry in the module.xml in there about your jar. Then you would need to edit the MANIFEST.MF file in the "standalone/deployments/teiid-connector-ws.rar" and add "org.jboss.teiid.translator.ws" on the Dependencies line at the end. Note if you created a new module, this name would reflect that! Then restart the server.

                                   

                                  Ramesh..
