我的Xpage应用程序有一个Kendo UI网格。通过调用自定义休息服务来填充网格，该服务支持我的一个托管bean连接到java类。
阅读效果很好，但我在删除工作时遇到了麻烦。它正在工作，然后发生了一些变化（无法弄清楚是什么），现在却根本没有。我不确定错误是在Kendo UI部分还是Rest服务部分，所以我将在这里发布。
我能够调试Java并且可以看到我正在使用doDelete方法，但是我无法获取获取文档并删除它所需的parm（UNID）。
java部分如下：
package com.scoular.rest;
import java.io.IOException;
import java.io.Writer;
import java.util.Vector;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.openntf.domino.Database;

import com.ibm.xsp.extlib.component.rest.CustomService;
import com.ibm.xsp.extlib.component.rest.CustomServiceBean;
import com.scoular.cache.CacheBean;
public class restPC extends CustomServiceBean {
@SuppressWarnings("unused")
private Database appData;
@Override
public void renderService(CustomService service, RestServiceEngine engine) throws ServiceException {
try {
HttpServletRequest request = engine.getHttpRequest();
HttpServletResponse response = engine.getHttpResponse();
response.setHeader("Content-Type", "application/json; charset=UTF-8");
String method = request.getMethod();
if (method.equals("GET")) {
this.doGet(request, response);
} else if (method.equals("DELETE")) {
this.doDelete(request, response);
}
} catch (Exception e) {
throw new RuntimeException(e);
}
}
private void doDelete(HttpServletRequest request, HttpServletResponse response) throws IOException {
// Map prmMap = request.getParameterMap();
// String id = prmMap.get("id").toString();
String prmUNID = request.getParameter("id");
Database DB = this.getAppData();
// String t = request.getParameter("unid");
Document tmpDoc = DB.getDocumentByUNID(prmUNID);
if (tmpDoc != null) {
tmpDoc.remove(true);
} else {
}
}
我只发布了java代码的相关部分。
以下是调用delta的Xpage的脚本部分（Kendo Grid）。

答案 0 :(得分：0)
解决方案。
我弄清楚我做错了什么。我发送了一个参数图，我需要得到一个参数图。
所以我在Java代理中的代码改为：
private void doDelete(HttpServletRequest request, HttpServletResponse response) throws IOException, NotesException {
Map<String, String[]> prmMap = request.getParameterMap();
String[] prmID = prmMap.get("unid");
Database DB = this.getAppData();
Document tmpDoc = DB.getDocumentByUNID(prmID[0]);
if (tmpDoc != null) {
tmpDoc.remove(true);
}
}
