Oracle Database Programming Using Java & Web Services
Using this information, the utility generates corresponding static methods in such a way that each of the operation has the same input parameters and return types as the corresponding operation in the published Web service. Then it adds all the static methods, corresponding to each of the supported operations, to a Java class. This utility reports any missing mandatory arguments and adds default values for the optional arguments. If you are using an SSL based Web service, then you must add SSL certificate to Keystore before running this utility or use the -ts command-line option to pass truststore path.
To access data that is returned from single or multiple Web service invocations, create a virtual table using a Web service data source.
This table lets you query a set of returned rows as though it were a table. The client calls a Web service and the results are stored in a virtual table in the database. You can pass result sets from function to function. This enables you to set up a sequence of transformation without a table holding intermediate results. To reduce memory usage, you can return the result set rows, a few at a time, within a function.
Oracle Database Programming Using Java And Web Services
By using Web services with the table function, you can manipulate a range of input values from single or multiple Web services as a real table. The table expression in the preceding example can be used in other SQL queries, for constructing views, and so on. Figure illustrates the support for virtual table. Provides an easy-to-use interface for Web services call-outs, thereby insulating developers from low-level SOAP programming.
Java classes running in the database can directly call external Web services by using the previously loaded Java proxy class or through dynamic invocation. Enables any SQL-enabled tool or application to transparently and easily consume dynamic data from external Web services. Enables application and data integration by turning external Web service into a SQL data source, making the external Web service appear as regular SQL table. This table function represents the output of calling external Web services and can be used in a SQL query.
The default value is the current directory. The default value is ojvm. The default value is defaultWebService. If you do not provide this value, then the output stream is displayed on System. This option is mutually exclusive with the -WADL option. This option is mutually exclusive with the -WSDL option.
If this environment variable is not set properly, then an error is thrown. This field is used when auto mode is specified.
