Hello All ,
Im new to Kendoui web and i have been getting my hands dirty with it . but i need help with this issue. im using kendo with java or jsp and i could read records from an oracle database unto the grid. and i could do an insert or create operation to the same oracle database. but i could not do an update or delete operation on the grid. i keep getting an error . i need somebody to tell me what im doing wrongly. here is a sample of my code :
<Script>
$("#grid").kendoGrid({
dataSource: {
transport: {
read: "listdepart.jsp",
create: {
url: "insertdepart.jsp",
type: "POST"
}
},
update:{
url: "updatedepart.jsp",
type:"POST"
},
destroy:{
url:"deleletdepart.jsp",
type:"POST"
},
parameterMap: function (options, operation) {
if (operation !== "read" && options.models) {
return { models: kendo.stringify(options.models) };
}
},
batch: true,
pageSize:5 ,
schema: {
data: function(result) {
return result.data || result;
},
total: function(result) {
var data = this.data(result);
return data ? data.length : 0;
},
model: {
id: "deptid",
fields: {
// id: { editable: false },
id: { validation: { required: true} ,type: "number" } ,
name: { validation: { required: true} }
}
}
}
},
//detailTemplate: kendo.template($("#template").html()),
//// detailInit: detailInit,
editable: true,
navigable: true, // enables keyboard navigation in the grid
pageable:true,
serverPaging: true,
groupable: true,
sortable:true ,
filterable:true,
// toolbar: [ "save", "cancel" ,"create" ], // adds save and cancel buttons,
toolbar: [ { name :"create" , text: "Add New Department" }], // adds save and cancel buttons,
editable:"popup" ,
columns: [{title: "Department ID", field: "deptid" }, { title: "Department Name",field: "name" } ,{ title: "Action", command: ["edit", "destroy"] }]
});
</script>
here are my jsp
for insert
===========
<%
response.setContentType("application/json");
try {
String dept_id = request.getParameter("deptid");
String dept_name = request.getParameter("name");
String jdbcname = "jdbc/orcl";
Context ctx = new InitialContext();
Context envCtx = (Context)ctx.lookup("java:/comp/env");
DataSource ds = (DataSource)envCtx.lookup(jdbcname);
Connection conn = ds.getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = null ;
// if (bsave.equals("savechanges")) {
String cmd2 = "insert into department (deptid , name) values ('"+dept_id+"' , '"+dept_name+"')";
rs = stmt.executeQuery(cmd2);
if (rs.next()) {
StringBuffer data = new StringBuffer("{\"data\":[");
data.append("{\"Insert was done sucessfully" + "\"},");
data.setCharAt( data.length()-1,']'); // replace last character with ]
data.append("}");
out.println(data.toString());
} else {
StringBuffer data = new StringBuffer("{\"data\":[");
data.append("{\"Insert was not done sucessfully" + "\"},");
data.setCharAt( data.length()-1,']'); // replace last character with ]
data.append("}");
out.println(data.toString());
conn.close();
}
//}
} catch(Exception e) {
out.println("Error: " + e);
e.printStackTrace();
}

for delete or update ( Almost the same just operations )

response.setContentType("application/json");
try {

rs = stmt.executeQuery(cmd2);
if (rs.next()) {
StringBuffer data = new StringBuffer("{\"data\":[");
data.append("{\"Delete Operation was sucessfully" + "\"},");

} catch(Exception e) {

Any help to get this working will really be appreciated.
