Hi All,
I am trying to invoke my webservice which having a method take one parameter
using REST my client code snippets is
public class RestClient
{
private static EndpointReference targetEPR = new
EndpointReference("http://localhost:8080/Axis2/rest/servicename/methodname?param0=47";);
public static void main(String[] args) {
try {
RESTCall call = new RESTCall();
Options options = new Options();
options.setTo(targetEPR);
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
options.setProperty(Constants.Configuration.ENABLE_REST,
Constants.VALUE_TRUE);
options.setProperty(Constants.Configuration.HTTP_METHOD,Constants.Configuration.HTTP_METHOD_GET);
call.setOptions(options);
OMElement result= call.sendReceive();
System.out.println(result.getFirstElement().getText());
}
catch (AxisFault axisFault) {
System.out.println(axisFault+":"+axisFault.getMessage());
}
catch (Exception axisFault) {
System.out.println(axisFault+":"+axisFault.getMessage());
}
}
I am able to call the method by browser by the same url that has-been
passed as a argument in EndPointReference()
but when I am calling this by client I am getting following error in log
file.
org.apache.axis2.AxisFault: For input string: "47?"; nested exception
is:
java.lang.NumberFormatException: For input string: "47?"; nested
exception is:
org.apache.axis2.AxisFault: For input string: "47?"; nested exception
is:
