Overview Following the "JavaScript and practice of advanced applications," after the launch json-rpc-for-java open source code, is only 100 lines of javascript code and less than 10 java super lightweight paper to achieve the rapid adoption of javaScript call java objects and Back to the arbitrary target lightweight framework, and support the cascade call, which means do not need additional JavaScript programming, it can be registered through the javascript call object and return to the java java object, if there are ways to return to the target, In this javascript in the java object to return to the variables, you can also continue to call it the way ..... This is the lightweight json-rpc-for-java the Shenqizhichu.

Java objects to the JavaScript object tables JavaScript object that Java objects java.lang.String String java.lang.Object String call java object toString (), after conversion to JavaScript java.util.Date, java.sql.Timestamp String But for yyyy-MM-dd HH: mm: ss.000, if at all Fenmiao 0, is: yyyy-MM-dd java.lang.Boolean Blooean the corresponding value: true, false java.lang.Character String single string, such as: 'c' java.lang.Short, java.lang.Integer, java.lang.Long, java.lang.Float, java.lang.Double, java.math.BigDecimal Number in JavaScript are for the number of objects, can be directly involved in the increase, subtraction, multiplication, with the exception of computing java.util.Map Object, for example: obj "key1", obj "key3", obj.key3, not only function of the way, of course, the function Object.prototype are still some properties java.util.List Array, for example: a 0, a 2. getList () In other words, can also exist List of objects, these objects can still have their own methods null null space object Object other Java objects such as: obj.displayName (), obj.aac001, can have properties and methods Features Automatically be caught In your java services prepared by the method does not require try (….) Catch (Exception e) (), this framework will you catch an error message, but you do not get javascript to the correct data, can be called asynchronous Object methods getErrMsg () access to unusual sources, the method in jcore.jsonrpc.common.JsonRpcObject in the package, which is java-based AJAX services category. JavaScript registered in the release of the Java clients You only need to call in JavaScript release () on the release of the Java objects registered resources, see detailed examples of works, or see " http://code.google.com/p/json-rpc-for-java/wiki/Wiki32 Cascade called functional Please do not understand the combination of local examples of the works to understand. 1, Java in the registration of objects myjsonrpc 2, JSP JavaScript in access to the object: var myjsonrpc = JsonRpcClient (). Myjsonrpc; 3, the call was registered java object methods getMyObj, the return of the java object TestDomain: var oDomain = myjsonrpc. getMyObj (); / / To the call to return to the java object methods alert (oDomain. toXml ()) Or: alert (myjsonrpc. getList () 1. ToXml ()); If toXml return or a composite of Java objects, you may continue to call in JavaScript, without the need for additional programming. Use Web.xml configuration Web.xml need to add the following configuration "

<servlet>

<servlet-name>

<servlet-class>

<load-on-startup>

<servlet-mapping>

<servlet-name>

<url-pattern>

import jcore.jsonrpc.common.JsonRpcObject;

public class TestObject extends JsonRpcObject implements Serializable ( Private static final long serialVersionUID = 1L;

Private List myList = new ArrayList (); Private Map map = new HashMap ();

Public TestObject () ( MyList.add ( "good"); MyList.add (new TestDomain ()); / / Map of the compound can also Add to object Map.put ( "first", "The first duty"); Map.put ( "p2", new Date ()); Map.put ( "domain", myList.get (1)); )

/ To Map object @ Return / Public Map getMap () ( Return map; )

/ Get an ordinary object @ Return / Public Object getStr () ( Return myList.get (0); )

/ Access to a composite target @ Return / Public Object getMyObj () ( Return myList.get (1); )

/ Get List object @ Return / Public List getList () ( Return myList; ) )

The preparation of their base class Similarly, you can achieve some of succession jcore.jsonrpc.common.JsonRpcObject base class, so in their own projects in a more convenient and practical, such as: package com.yinhai.yhsi2.web.common;

import com.yinhai.webframework.session.UserSession; import jcore.jsonrpc.common.JsonRpcObject;

public abstract class Yhsi2JsonRpcObj extends JsonRpcObject (

Private UserSession us = null; Public Yhsi2JsonRpcObj () ( Super (); )

Public UserSession getUs () ( If (null == us) Us = UserSession.getUserSession (getRequest ()); Return us; ) )

AJAX Java class registration services / / Note that the class must be registered is to be examples of the type

jcore.jsonrpc.common.JsonRpcRegister.registerObject (us, "myjsonrpc", test.TestObject.class);

Test.TestObject.class way is to use multiple registration does not guarantee test.TestObject been repeatedly registered the implementation of several examples, and then to improve performance and allow multiple registration - indeed, within only registered once. Registration of their own kind of preparation Of course, you can also inherit jcore.jsonrpc.common.JsonRpcRegister in the application menu in order to make the switch when the release of resources, such as: package com.yinhai.yhsi2.web.common; import javax.servlet.http.HttpServletRequest;

import jcore.jsonrpc.common.Content; import jcore.jsonrpc.common.JSONRPCBridge;

import com.yinhai.webframework.session.UserSession; import jcore.jsonrpc.common.JsonRpcRegister;
