Using the UDDI Inquiry API

The UDDIProxy PowerBuilder extension class enables you to search UDDI registries for a Web service that you want to access. For a description of this extension class and its methods, see the PowerBuilder Extension Reference or the online Help.

Example code

The following is example code using all the methods in the UDDIProxy class. It searches an IBM UDDI registry by service name (Weather) and business name (IBM), using the same search options (case sensitivity and a maximum of 5 rows returned):

uddiproxy proxy

int ret

proxy = create uddiproxy

ret = proxy.setinquiryurl   (“http:/www-3.ibm.com/services/uddi/inquiryapi”)

ret = proxy.setoption (false, true, 0, 5)

int count, count2

string businessName[], businessDescription[]

string businessKey []

string servicename[], servicedescription[]

string servicekey [], wsdl [ ]

ret = proxy.findService(“Weather”,count,serviceName, &
  serviceDescription, serviceKey, businessName, wsdl)

int i, j

FOR i = 1 TO count

   messagebox(servicename[i], &
     servicedescription[i]+servicekey[i]+wsdl[i])

NEXT

proxy.findbusiness(“IBM”, count, businessName, &
  businessDescription, businessKey)

FOR i = 1 TO count

   messagebox(businessName[i], &
     businessDescription[i] + businessKey[i])

  proxy.getbusinessdetail (businessKey [i], count2, &
     servicename, servicedescription, servicekey, wsdl)

  FOR j = 1 TO count2

   messagebox(servicename[j], &
     servicedescription[j]+servicekey[j]+wsdl[j])

  NEXT

NEXT

destroy proxy

Troubleshooting UDDI API calls

You can turn on logging to track down any failures on method calls to the UDDIProxy object. The PowerBuilder Java service class path must include the log4j.properties configuration file to turn on logging. The following is an example of a log configuration file for a UDDI search:

#log4j.debug=true

#log all level

#log4j.rootCategory=DEBUG, lf5

#only log com.sybase.powerbuilder.uddi

log4j.category.com.sybase.powerbuilder.uddi=DEBUG,     dest2, lf5

#dest1

#log4j.appender.dest1=org.apache.log4j.ConsoleAppender

#log4j.appender.dest1.layout=
    org.apache.log4j.PatternLayout

#log4j.appender.dest1.layout.ConversionPattern=
    %-5p: %-5r: %-5c: %l: %m%n

#dest2

log4j.appender.dest2=org.apache.log4j.FileAppender

log4j.appender.dest2.layout=
    org.apache.log4j.PatternLayout

log4j.appender.dest2.layout.ConversionPattern=
    %-5p: %l: %m%n

log4j.appender.dest2.File=c:/mylog.txt

#lf5

log4j.appender.lf5=
    org.apache.log4j.RollingFileAppender

log4j.appender.lf5.File=c:/mylog.lf5

log4j.appender.lf5.layout=
    org.apache.log4j.PatternLayout

log4j.appender.lf5.layout.ConversionPattern=
