Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
this is the part of my code (modifynews.jsp) :

   <%   
   String newsid=request.getParameter("newsid");
   String query = "select from " + news.class.getName()+" where id =="+newsid;
   PersistenceManager pm = pmf.get().getPersistenceManager();
   List<news> news1 = (List<news>) pm.newQuery(query).execute();
   news newsItem = news1.get(0); //to get the first item.
   %>

   <div>
   <label for="title">Title</label>
   <input type="text" name="title" id="title" value="<%=newsItem.getTitle()%>"/>
   <br>
      <br>
      Guest:
      <textarea name="content" id="editor1" rows="5" cols="60">
      <%=newsItem.getContent()%></textarea>
      <br>
   <input type="submit" value="Update News"/>
   <input type="hidden" name="newsid" id="newsid" value="<%=newsItem.getId()%>"/>
   </div>

An issue tracker is to report problems (and provide a testcase that 
demonstrates the problem) not to ask questions. Use Stackoverflow.com for 
asking questions
