Java learning: Calling Java Web Service

first write a Java class: awbmodel (equivalent to the object to be transmitted in the Web Service)

Package webservicesample; public class awbmodel {private string _ a1 = "_ A1"; Public String geta1 () {return _ A1;} public void seta1 (string value) {This. _ a1 = value;} private string _ a2 = "_ A2"; Public String geta2 () {return _ A2;} public void seta2 (string value) {This. _ a2 = value;} private string a3 = "A3"; Public String geta3 () {return A3;} public void seta3 (string value) {This. a3 = Value ;} Private string A4 = "A4"; Public String geta4 () {return A4;} public void seta4 (string value) {This. a4 = value;} private string A5 = "A5"; Public String geta5 () {return A5;} private string A6 = "A6"; Public void seta6 (string value) {This. a6 = value;} Public String A7 = "A7"; // Private string _ A8 = "A8"; Public String get_a8 () {// return _ A8; return "";} public void set_a8 (string value ){/ /This. _ A8 = value;} Public String sayhelloa () {return "Hello! ";}}

then write an AWB class (equivalent to the Web Service Interface + Implementation)

Package webservicesample; public class AWB {public awbmodel getawbmodelbyno () {awbmodel A = new awbmodel ();. seta1 ("a1_new"); return a;} private string _ b1 = "_ b1"; Public String getb1 () {return _ b1;} public void setb1 (string value) {This. _ b1 = value;} private string _ b2 = "_ b2"; Public String getb2 () {return _ b2;} public void setb2 (string value) {This. _ b2 = value;} private string B3 =" B3 "; Public String getb3 () {return B3;} public void setb3 (string value) {This. b3 = value;} private string B4 = "B4"; Public String getb4 () {return B4;} public void setb4 (string value) {This. b4 = value;} private string B5 = "B5"; Public String getb5 () {return B5;} private string B6 = "B6"; Public void setb6 (string value) {This. b6 = value;} Public String B7 = "B7"; Public String sayhello B () {return "Hello B! ";}}

After the Web Service is encapsulated in the jbuilder2006 environment and published to WebLogic, the content of the WSDL can be found in:

Note:BecauseA5 only has the get Method,A6 only has the Set MethodThe resulting WSDL automatically removes these two "attributes" (this will be generated in the true sense when C # is used to call the Java Web service.. Net Property), other custom methods (such as sayhelloa) are discarded (that is, these methods are not automatically serialized), and it is interesting that"_ A8", Awbmodel. java only defines the set_a8 (string value) and get_a8 () methods, and does not declare the private variable of _ A8 at all. However, Java is automatically considered as a private member with "_ A8" already exists; in addition, the public variables declared directly do not change the case sensitivity in WSDL, and they are stillA7The other setxxx and getxxx methods are all removed from set/get, and the first letter is lowercase, that isXXX.

After adding a service reference in vs.net, client calls such as xxxclient, xxxchannel, and proxy class are automatically generated.CodeSimilarly, after make, JBuilder will also generate the client code sample package awb_client.jar. decompress the package and check the content of awbmodel. Java:

It is basically the same as the one seen in the WSDL, but there are some interesting small changes compared with the original awbmodel. Java: defined in the original awbmodel. JavaPrivate member, Always changedLowercaseAnd the automatically added"_ A8"But againUppercase.

The following describes how to call Web Service in Java:

Create a Java project and reference the awb_client.jar package automatically generated by JBuilder.

Package jmyang. web_service_call; import webservicesample. generated. *; import Java. io. ioexception; import javax. XML. RPC. serviceexception; public class wscalldemo {public void callservice () {string wsdlurl = "http: // 127.0.0.1: 7001/mywebservice/AWB? WSDL "; try {AWB service = new awb_impl (wsdlurl); awbport Port = service. getawbport (); awbmodel result = port. getawbmodelbyno (); system. out. println ("awbmodel. a1 = "+ result. geta1 ();} catch (ioexception e) {e. printstacktrace ();} catch (serviceexception E2) {e2.printstacktrace ();}}}
 

In this way, you can call it.

Of course,. Net can also call the Web Service written in Java. Add service reference in vs.net. Enter the service address http: // 127.0.0.1: 7001/mywebservice/AWB? WSDL vs.net will automatically generate other code, such as the proxy class, like adding a reference to the WCF/asmx service. Let's look at the automatically generated awbmodel class.

We can see that A1, A2, A3, A4, A7, and _ A8 all appear in the property mode.

The calling code of C # is simple as follows:

 
Using (yjm. awbportclient client = new awbportclient () {VAR model = client. getawbmodelbyno (); console. writeline ("a1 =" + model. a1); console. writeline ("A2 =" + model. a2); console. writeline ("A3 =" + model. a3); console. writeline ("A4 =" + model. a4); console. writeline ("A7 =" + model. a7); console. writeline ("_ A8 =" + model. _ A8); console. read ();}
