I need to update a DataSourceTextField. Basically I do this in my code:
DataSourceTextField partDataSourceField = new DataSourceTextField(
partFieldName, constants.partTitle());
partDataSourceField.setValueMap(partCodesList);
documentsResultDataSource.setFields(partDataSourceField,
titleDataSourceField);
That code, generates a "part" list on the DataSource for me to filter the results.
What I've been trying is this dynamically change this list to set it to show only the values that are available on the results. I've tried this with no avail:
DataSourceField partField = documentsResultDataSource.getField(partFieldName);
LinkedHashMap<String, String> partCurrentCodesList = new LinkedHashMap<String, String>();
partCurrentCodesList.put("Test", "Test");
partField.setValueMap(partCurrentCodesList);
Is it possible to accomplish what I need?
I deleted the DataSourceTextField and then :
documentsResultDataSource.setFields(partDataSourceField,
titleDataSourceField);
This is sub-optimal but the best solution I found.

I am trying return key value by using JObject. I am getting the ObjcetId after insert the value in mongodb. I am using JObject to return the value as key value pair. By using the bellow code i assing the objectid to the key.
JObject returnId= new JObject();
dynamic id = Document["_id"].AsObjectId;
returnValue = returnId.Add("_id",id);
I am getting unhandle exception in the third line. Why i am getting this is issue and how can i solve it.
i want return the value like bellow
"_id":"12345667889"
can any one try to help me.
Thank you...
I change the bellow code
JObject returnId= new JObject();
to
BsonDocument returnId = new BsonDocument()
Now its working fine.
I am developing the Invoice printing System using the Jasper report, Now I have can print the report but it will take 2000ms to load the report, also 2000ms take to start the printing,
These are I am using the JAR FILES,
commons-beanutils-1.4
commons-digester-1.7
commons-logging-1.0.3
commons-beanutils-1.4
groovy-all-1.7.5
batik-all-1.7
barcode4j-2.1
itextpdf-5.1.0
jasperreports-6.0.3
xercesImpl-2.11.0
xml-apis-ext-1.3.04
preparedStatement = conn.prepareStatement(sqlString);
resultSet = preparedStatement.executeQuery();
if (resultSet.next()) {
HashMap<String, Object> hm = new HashMap<>();
JasperDesign jasperDesign = JRXmlLoader.load(new File(
"C:/Invoice/Invoice.jrxml"));
JRDesignQuery designQuery = new JRDesignQuery();
designQuery.setText(sqlString);
jasperDesign.setQuery(designQuery);
JasperReport jasperReport = JasperCompileManager
.compileReport(jasperDesign);
JasperPrint jasperPrint = JasperFillManager.fillReport(
jasperReport, null, conn);
for (int i = 0; i < copies; i++) {
JasperPrintManager.printReport(jasperPrint, false);
}
JasperViewer.viewReport(jasperPrint);
The above code I used to print the report but, getting too much time to load the report. Please suggest my fault and some other idea...
I guess the SQL query could be the problem. Have you tried executing it in a sql query tool and check how long it runs? Optimizing it should yield a performance win.
You are also running the query twice: before the report and when you are filling it via the JasperFillManager.fillReport() call.
If there are no specific reasons to check wheter the query contains any records, I would recommand to let JasperReports handle the query and the case that no record is found. You can determine a specific behaviour in that case via the "When No Data Type" property in the reportdesign.
I would like to create a table in my Jasper Report.
This could be done (and it is done :-) ) in iReport, but the content of the table (for example names of the columns) are changing, so I would like to create the report solely from JAVA code (by not using jrxml files).
How is it possible?
So far, this is what I have done (the main parts only):
//table component
final StandardTable table = new StandardTable();
final StandardColumn col1 = new StandardColumn();
final DesignCell col1Header = new DesignCell();
final JRDesignStaticText textElement = new JRDesignStaticText();
col1Header.addElement(textElement);
col1.setDetailCell(col1Header);
table.addColumn(col1);
/datasource
final JRDesignDatasetParameter param = new JRDesignDatasetParameter();
param.setName("REPORT_DATA_SOURCE");
final JRDesignExpression exp = new JRDesignExpression("$P{REPORT_DATA_SOURCE}");
param.setExpression(exp);
//datasetrun
final JRDesignDatasetRun drs = new JRDesignDatasetRun();
table.setDatasetRun(drs);
drs.addParameter( param );
How to continue?
Thank you,

In case anyone stumbles upon the same problem (and for future myself :-) ) here is how to continue the code above, to add a table element to the summary of the report:
//create reportElement (inside componentelement)
JRDesignComponentElement reportElem = new JRDesignComponentElement();
//reportElem.setKey("table");
reportElem.setComponentKey(new ComponentKey("http://jasperreports.sourceforge.net/jasperreports/components", "jr", "table"));
reportElem.setComponent(table);
reportElem.setHeight(100);
reportElem.setWidth(100);
//add to summary
jRSummary.addElement(reportElem);
(the hard part was to find out how to create the ComponentKey object)
Note: in order to use the table, the subdataset element needs to be created as well.
For htmlComponent the ComponentKey should be:
new ComponentKey("http://jasperreports.sourceforge.net/htmlcomponent", "jr",
"html");
I can send callback param(s) and it works perfectly as long as I am only sending some primitive types like String. But the same thing does not work for even the simplest POJO. PrimeFaces guide says that the RequestContext.addCallbackParam() method can handle POJOs and it coverts them into JSON. I don't know why it's not working in my case.
Has anybody done that?
Solution found! ---------------------------------------------------------------------
I did some research and found the answer to this question.
And the solution was to use some JSON library (right now I am using GSON) to convert Java objects to JSON objects.
new Gson().toJson(someJavaObj)
returns string. Just send the string as the param and on the client side using js' eval or some js library's function to turn that into JSON again.
Actually, it was pretty clean and simple.
Sorry I actually did not post the solution. Below is the my solution -
Action method in the backing bean -
public void retrievePieData() {
List<String> categories = new ArrayList<String>();
categories.add("Electronic");
categories.add("Food");
categories.add("Liguor");
categories.add("Stationary");
categories.add("Mechanical");
List<Integer> itemCounts = new ArrayList<Integer>();
itemCounts.add(5);
itemCounts.add(20);
itemCounts.add(1);
itemCounts.add(50);
itemCounts.add(10);
RequestContext reqCtx = RequestContext.getCurrentInstance();
reqCtx.addCallbackParam("categories", new Gson().toJson(categories));
reqCtx.addCallbackParam("itemCounts", new Gson().toJson(itemCounts));
}
PrimeFaces p:commandButton in the view -
<p:commandLink action="#{pieDataProvider.retrievePieData}" oncomplete="feedPieData(xhr, status, args);" value="Pie chart demo" update="pieData" />
Javascript function -
function feedPieData(xhr, status, args) {
var categories = eval('(' + args.categories + ')');
var itemCounts = eval('(' + args.itemCounts + ')');
options.xAxis.categories = categories;
var series = {
data: []
};
series.name = new Date().toString();
series.data = itemCounts;
options.series = [series];
chart = new Highcharts.Chart(options);
}
I would really appreciate and welcome any suggestion or opinion.
Thank you!
I'm trying to build a custom ServerSyncProvider
right now. I'm trying to understand the GetScema Method.
I'm trying to build a dataSet and associate it to SyncSchema class
one of my table columns is a nvarchar(50).
Here is what I'm doing this:
DataColumn column = new DataColumn();
column.ColumnName = "Name";
column.DataType = typeof(String);
column.MaxLength = 55;
table.Columns.Add(column);
But it turns out that on my client side, this column becomes nvarchar(1)
any idea?
Thanks a lot for helping me.
Use this code:
column.ExtendedProperties.Add("ColumnLength", 50);
