ice 远程调用，使用application类

[["java:package:com.demo"]]module zhz{    struct Person{    string name;    string password;    };    dictionary<long,Person>PersonList;    interface PersonInter{    void sendUser(Person p);    Person returnPerson();    };};

? ice文件添加一个Person对象，一个字典表，表中为person对象，另外是一个方法调用。

client.java

?PersonInterI.java

package test;import org.apache.log4j.Logger;import Ice.Current;import com.demo.zhz.Person;import com.demo.zhz._PersonInterDisp;public class PersonInterI extends _PersonInterDisp {/** * Logger for this class */private static final Logger logger = Logger.getLogger(PersonInterI.class);@Overridepublic void sendUser(Person p, Current __current) {if (logger.isDebugEnabled()) {logger.debug("sendUser(Person, Current) - start"); //$NON-NLS-1$} System.out.println("Person = "+p.name+":"+p.password);if (logger.isDebugEnabled()) {logger.debug("sendUser(Person, Current) - end"); //$NON-NLS-1$}}@Overridepublic Person returnPerson(Current __current) {// TODO Auto-generated method stubreturn null;}}

?个人认为跨语言有必要使用，如果都是java应用的话，不觉得没有必要，毕竟java的远程调用方式比较多。

以上例子需要安装slice2java的eclipse插件。。
