You can make an AJAX request like any other requests:

可以像其他请求一样发出AJAX请求:

$.ajax( {
type:'Get',
url:'http://mysite.com/mywebservice',
success:function(data) {
 alert(data);
}

})

EDIT:

编辑:

The OP was not looking to use cross-domain requests, but jQuery supports JSONP as of v1.5. See jQuery.ajax(), specificically the crossDomain parameter.

OP没有考虑使用跨域请求，但是jQuery在v1.5中支持JSONP。参见jQuery.ajax()，具体来说是跨域参数。

The regular jQuery Ajax requests will not work cross-site, so if you want to query a remote RESTful web service, you'll probably have to make a proxy on your server and query that with a jQuery get request. See this site for an example.

常规的jQuery Ajax请求不会跨站点工作，因此，如果您想查询一个远程的RESTful web服务，您可能需要在服务器上做一个代理，并使用jQuery get请求查询。请参见本网站的示例。

~~If it's a SOAP web service, you may want to try the jqSOAPClient plugin.~~

如果是SOAP web服务，您可能想尝试jqSOAPClient插件。

I blogged about how to consume a WCF service using jQuery:

我写了一篇关于如何使用jQuery使用WCF服务的博文:

http://yoavniran.wordpress.com/2009/08/02/creating-a-webservice-proxy-with-jquery/

The post shows how to create a service proxy straight up in javascript.

本文展示了如何用javascript直接创建服务代理。

Incase people have a problem like myself following Marwan Aouida's answer ... the code has a small typo. Instead of "success" it says "sucess" change the spelling and the code works fine.

万一人们像我一样对马尔文·阿维达的答案有疑问……这段代码有一个小错误。它不是说“成功”，而是说“成功”改变了拼写，代码运行良好。

In Java, this return value fails with jQuery Ajax GET:

在Java中，jQuery Ajax GET返回值失败:

return Response.status(200).entity(pojoObj).build();

But this works:

但是这个工作原理:

ResponseBuilder rb = Response.status(200).entity(pojoObj);
return rb.header("Access-Control-Allow-Origin", "*").build();

----

Full class:

完整的类:

@Path("/password")
public class PasswordStorage {
    @GET
    @Produces({ MediaType.APPLICATION_JSON })
    public Response getRole() {
        Contact pojoObj= new Contact();
        pojoObj.setRole("manager");

        ResponseBuilder rb = Response.status(200).entity(pojoObj);
        return rb.header("Access-Control-Allow-Origin", "*").build();

        //Fails jQuery: return Response.status(200).entity(pojoObj).build();
    }
}
