Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1 when I run my web service client - axis2

Question

I create a Dynamic web project with name 'testUpdate' (and of course I don't forget to change the dynamic web module version to 2.5 and in configuration I choose Axis 2 web service
I add to my Dynamic web project these two classes :
SimpleService .java and PWCBHandler.java
I right click on SimpleService.java -> New ->Other -> Web Service to create my web service
I don't forget to copy all the jar files from rampart distribution to testUpdate/ WebContent/WEB_INF/lib and all .mar modules into testUpdate/ WebContent/WEB_INF/modules
I change services.xml file so it looks like
<service name="SimpleService" >
<module ref="rampart" />

<parameter name="InflowSecurity">
<action>
<items>UsernameToken</items>
<passwordCallbackClass>com.gismo.PWCBHandler</passwordCallbackClass>
</action>
</parameter>
</service>
I right click on testUpdate -> RUN AS _> Run on Server (and my web service is deployed successfully)
File -> New -> Other -> Web Service Client
and in Service Definition I paste the url of the wsdl file of SimpleService
( http://localhost:9091/testUpdate/services/SimpleService?wsdl)
I add testcl.java class to my web-service client. Here is the code
public class testCL {
public static void main(String[] args) throws Exception {
if (args.length != 2) {
System.out.println(args.length);
System.out
.println("Usage: $java Client endpoint_address client_repo_path");
}
ConfigurationContext ctx = ConfigurationContextFactory
.createConfigurationContextFromFileSystem(args[1], args[1]
+ "/conf/axis2.xml");
ServiceClient client = new ServiceClient(ctx, null);
Options options = new Options();
options.setAction("urn:echo");
options.setTo(new EndpointReference(args[0]));
client.setOptions(options);
OMElement response = client.sendReceive(getPayload("Hello world"));
System.out.println(response);
}
private static OMElement getPayload(String value) {
OMFactory factory = OMAbstractFactory.getOMFactory();
OMNamespace ns = factory.createOMNamespace("com.gismo/xsd", "ns1");
OMElement elem = factory.createOMElement("echo", ns);
OMElement childElem = factory.createOMElement("param0", null);
childElem.setText(value);
elem.addChild(childElem);
return elem;
}
}
I don't forget to change webSercice_client/WebContent/axis2-web/conf/axis2.xml and add
<module ref="rampart"/>
<parameter name="OutflowSecurity">
<action>
<items>UsernameToken</items>
<user>bob</user>
<passwordCallbackClass>com.gismo.PWCBHandler</passwordCallbackClass>
</action>
</parameter>
But when I run testCl as Java Application it gives me an exception
Usage: $java Client endpoint_address client_repo_path
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
at com.gismo.testcl.main(testcl.java:24)

My psychic debugging powers tell me that you ran it without providing two command-line arguments. You can see the error message "Usage: $java Client endpoint_address client_repo_path" is present in your program output, meaning that you didn't supply two command-line arguments, so args[1] may not be valid. Your program doesn't exit after checking the number of command-line arguments, so it tries to access args[1] after complaining that the program was run incorrectly.
if (args.length != 2) {
System.out.println(args.length);
System.out
.println("Usage: $java Client endpoint_address client_repo_path");
}
ConfigurationContext ctx = ConfigurationContextFactory
.createConfigurationContextFromFileSystem(args[1], args[1]
+ "/conf/axis2.xml");
