如何将表值从一个servlet传递到另一个servlet

Question

我正在从SPARQ查询中检索结果并将其显示在表上。现在，当我单击表格行时，应该在另一页上获得详细信息。我应该怎么做？我当前的servlet是ServletComparison。需要显示详细信息的servlet是CandidateDetails

while(rs.hasNext())
        {
            QuerySolution sol = rs.nextSolution();
            RDFNode object = sol.get("label");
            RDFNode object2 = sol.get("label2");
            RDFNode object3 = sol.get("label3");
            RDFNode object4 = sol.get("label4");

            str += "<tr><td> "+ object +" </td>" +
                    "<td> "+ object2 +" </td>" +
                    "<td> "+ object3 +" </td>" +
                    "<td> "+ object4 +" </td>" +
                    "<td> <form action=\"CandidateDetails\" 
                           method=\"get\">\n" +
                    "       <input type=\"submit\" value = \"Details\">\n" +
                    "     </form> </td> " +
                    "</tr>";
        }
