6-6 Getting Started With JAX-WS Web Services for Oracle WebLogic Server
The example also shows how to invoke an operation that has a user-defined data type examples.webservices.simple_client.BasicStruct as an input parameter
and return value. The clientgen Ant task automatically generates the Java code for this user-defined data type.
Because the clientgen packageName attribute was set to the same package name as the client application, we are not required to import the clientgen-generated
files.
package examples.webservices.simple_client; This is a simple Java application that invokes the
the echoComplexType operation of the ComplexService Web service. public class Main {
public static void mainString[] args { ComplexService test = new ComplexService;
ComplexPortType port = test.getComplexPortTypePort; BasicStruct in = new BasicStruct;
in.setIntValue999; in.setStringValueHello Struct;
BasicStruct result = port.echoComplexTypein; System.out.printlnechoComplexType called. Result: + result.getIntValue +
, + result.getStringValue; }
}
In the preceding example:
■
The following code shows how to create a ComplexPortType stub: ComplexService test = new ComplexService,
ComplexPortType port = test.getComplexPortTypePort; The ComplexService class implements the JAX-WS Service interface. The
getComplexServicePortTypePort method is used to return an instance of
the ComplexPortType stub implementation.
■
The following code shows how to invoke the echoComplexType operation of the ComplexService
Web service: BasicStruct result = port.echoComplexTypein;
The echoComplexType operation returns the user-defined data type called BasicStruct
.
6.2.4 Compiling and Running the Client Application
Add javac tasks to the build-client target in the build.xml file to compile all the Java files both of your client application and those generated by clientgen into
class files, as shown by the bold text in the following example:
target name=build-client clientgen
wsdl=http:{wls.hostname}:{wls.port}complexComplexService?WSDL destDir=clientclasses
packageName=examples.webservices.simple_client type=JAXWS
javac
srcdir=clientclasses destdir=clientclasses
Invoking Web Services 6-7
includes=.java javac
srcdir=src destdir=clientclasses
includes=exampleswebservicessimple_client.java
target In the example, the first javac task compiles the Java files in the clientclasses
directory that were generated by clientgen, and the second javac task compiles the Java files in the exampleswebservicessimple_client subdirectory of the
current directory; where it is assumed your Java client application source is located.
In the preceding example, the clientgen-generated Java source files and the resulting compiled classes end up in the same directory clientclasses. Although
this might be adequate for prototyping, it is often a best practice to keep source code even generated code in a different directory from the compiled classes. To do this, set
the destdir for both javac tasks to a directory different from the srcdir directory. To run the client application, add a run target to the build.xml that includes a call to
the java task, as shown below:
path id=client.class.path pathelement path=clientclasses
pathelement path={java.class.path} path
target name=run java
fork=true classname=examples.webServices.simple_client.Main
failonerror=true classpath refid=client.class.path
target
The path task adds the clientclasses directory to the CLASSPATH. The run target invokes the Main application, passing it the URL of the deployed Web service as
its single argument.
See Section 6.2.5, Sample Ant Build File for a Java Client
for a full sample build.xml
file that contains additional targets from those described in this procedure, such as clean.
Rerun the build-client target to regenerate the artifacts and recompile into classes, then execute the run target to invoke the echoStruct operation:
prompt ant build-client run You can use the build-client and run targets in the build.xml file to iteratively
update, rebuild, and run the Java client application as part of your development process.
6.2.5 Sample Ant Build File for a Java Client
The following example shows a complete build.xml file for generating and compiling a Java client. See
Section 6.2.1, Using the clientgen Ant Task To Generate Client Artifacts
and Section 6.2.4, Compiling and Running the Client Application
for
explanations of the sections in bold.
