I am new to Java Web. I am using netbeans 7.0.1 and glassfish 3 to develop a web application. I am almost through with all data input and Now I want to create reports & graph. Requirement is to create charts (pie/bar/line based on user selection) with dynamic data (from database / datatable user can apply filters on data). I tried using Primefaces but it gives below error with simple example given in primeface show case:
javax.faces.event.AbortProcessingException:
/pages/analyst/analyse.xhtml #65,151
actionListener="#{analysis.bar()}": java.lang.NoClassDefFoundError:

java.lang.NoClassDefFoundError: org/primefaces/component/chart/series/ChartSeries
The mentioned class was introduced in PrimeFaces 3.0 and was thus not available in PrimeFaces 2.x and older.
Given the fact that the PrimeFaces 3.0 specific XML namespace http://primefaces.org/ui and all the <p:xxx> tags in your code did apparently not result in a Facelets compile error, that can only mean that you've both PrimeFaces 2.x and 3.x libraries in your webapp's runtime classpath wherein the 2.x one got precedence in classloading.
Get rid of the offending old PrimeFaces 2.x library from your webapp's runtime classpath and this problem should then disappear.

To make it short, in a jsf page, I have 2 rich:dataTable.
The first one is loaded within the onLoad event of the page.
The second one is loaded when a row is clicked within the first.
Both tables have a rich:dataScroller.
Everything is working fine except that I don't find how to make working the actionListener of the dataScroller.
Schematically I have
<rich:collapsiblePanel>
<h:form>
<h:panelGroup id="table1">
<rich:dataTable>
<f:facet name="header">
</f:facet>
<rich:column>
</rich:column>
<f:facet name="footer">
<rich:dataScroller reRender="table1,table2" page="1" actionListener="#{mybean.ac}"/>
</f:facet>
</rich:dataTable>
</h:panelGroup>
<h:panelGroup id="table2">
<rich:dataTable rendered="#{myBean.rowSelected != null}">
<f:facet name="header">
</f:facet>
<rich:column>
</rich:column>
<f:facet name="footer">
<rich:dataScroller reRender="table1" page="1" />
</f:facet>
</rich:dataTable>
</h:panelGroup>
</h:form>
</rich:collapsiblePanel>
In my bean I have
Long rowSelected;
public void ac()
{
rowSelected = null;
System.out.println("xxxxxxxxxxxxxxxxxxxxxxxxxx");
}
But nothing to do, never succeeded to make it work.
I also tried without any différence
public void ac(ActionEvent ae) - using javax.faces.event.ActionEvent
and
action="#{mybean.ac}"
<rich:dataScroller> has neither action nor actionListener attributes. If you're using RichFaces 4.3 you can use scrollListener. See the docs.
I want to export a data table in csv,pdf format in primefaces 4.0 .For that I used following code :
<p:dataTable var="valuesTable" value="#{userBean.groupResultList}"
paginator="false" id="valuesTable" resizableColumns="true"
rendered="#{not empty userBean.groupResultList}">
<p:column headerText="Group" id="grp"> #{valuesTable.groupName}</p:column>
<p:column headerText="Technical Knowledge" id="tk">
#{valuesTable.tkValue}
</p:column>
<p:column headerText="Project Management" id="pm">
#{valuesTable.pmValue}
</p:column>
<p:column headerText="Growth" id="ga">
#{valuesTable.gaValue}
</p:column>
<f:facet name="footer">
<h:commandLink>
<p:graphicImage value="/images/xml.jpeg" width="20" height="20" />
<p:dataExporter target="valuesTable" type="xml" fileName="Data_XML" />
</h:commandLink>
</f:facet>
</p:dataTable>
Data table displays correct data in each cell when I run the application.
But when I try to export it in csv or pdf format, rather then exporting actual numbers (or values of the object) it is exporting "#{valuesTable.groupName}" "#{valuesTable.tkValue}" ,"#{valuesTable.pmValue}" ,"#{valuesTable.gaValue}" for each object in csv file.
CSV file Content :
#{valuesTable.groupName} #{valuesTable.tkFormatedValue} #{valuesTable.pmFormatedValue} #{valuesTable.gaFormatedValue}
Data Table Content :
Group Name Technical Knowledge Project Management Growth
India .8 .7 1.0
I don not know why it is exporting the data table in this way..
Please Help
Thanks
I had a similar problem once with the dataTable exporter.
You have to use an outputText like this:
<h:outputText value="#{valuesTable.tkValue}"/>
inside all the column tags, in order to see the values properly.
Your column would become:
<p:column headerText="Technical Knowledge" id="tk">
<h:outputText value="#{valuesTable.tkValue}"/>
</p:column>
Replace all your columns and try that!
Hope it helps!
And also I think the headers are not ok. You have to use an f:facet tag like this:
<p:column id="tk">
<f:facet name="header">
<h:outputText value="Technical Knowledge" />
</f:facet>
<h:outputText value="#{valuesTable.tkValue}"/>
</p:column>
Now you should also see the headers in the export CSV file.
DataTable export is not working in Primefaces 4.0
Step 1: You need to add jars for exporting csv ,pdf file .
itext-1.1.4.jar
Step 2: DataExplorar.xhtml
<?xml version="1.0" encoding="UTF-8"?>

Good evening from Sweden!
I try to get a primefaces datatable to refresh. I tried various hints and solutions but nothing is working.
The button triggers a search in the DB and if I refresh the paga manually or if I use the tables sorting-function the result is shown.
Means the code in the backing bean works. But no automatic refresh directly after the button is clicked..
The bean scope is Session.
Here is the page

Any help or hints?
With regards

EDIT
Hello and thanx for the offer to help!
As you guessed searchresult is a list and the Getter is defined by
List<sbasUserList> searchresult;
public List<sbasUserList> getSearchresult() {
return searchresult;
}
search_grp is a method of the backing bean:
public String searchgrp_user(){
//FacesContext context = FacesContext.getCurrentInstance();
ObjectContainer db = this.connBD("sms");
ObjectSet<sbasUserList> res;
this.searchresult = new ArrayList<sbasUserList>() ;
Query query=db.query();
query.constrain(sbasUserList.class);
query.descend("groupname").constrain(this.searchword).like();
query.descend("type").constrain('P').or(query.descend("type").constrain('M'));
query.descend("teacher").constrain(searchteacher).contains();
res = query.execute();
this.searchresult.addAll(res);
System.out.println(this.searchresult.size());
db.close();
return "";
}
The table is filled with the right dat if i update manually the browser. (F5) but certainly would like to have this done automatically.
Sorry folks! The glassfish server I was using wasn't setup right. It showed not all of the errors in the log file. I did a complete new setup of the whole IDE (new Eclipse, new glassfish server, thanx BalusC for the incredible tutorial!!!) and I found all errors. Now it works like it should!

Im using Jsf 2.0 and primefaces exstensions component pe:layout to create a page with left navigation menu bar ,bottom footer and center pane for content everthing works fine but when ever i add primefaces datatable (p:datatable) in the center pane the header and footer layouts are preserved but the left pane disappears and the center pane occupies the entire page. I tried setting width and height of the datatable but nothing seems to work. The page displays correctly without datatable. Any help would be greatly appreciated.

This is very confusing. I'm working on a simple app for a class and followed the examples but the damn Bean property just won't set. Code follows:
Bean code:
import java.io.Serializable;
import javax.faces.bean.*;
import javax.faces.event.*;
#ManagedBean(name="dist") // or #Named("dist")
#SessionScoped
public class DistanceConvertBean implements Serializable{
private static final double MILESTOKM = 1.609344;
private static final double KMTOMILES = 0.62137;
private double input;
private String convertTo;
private String outputString;
Eclipse generated getters and setters
Index.xhtml code:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<h:body>
<h:panelGrid columns="3">
<h:outputText value="Distance:"/>
<h:inputText id="inDist" value="#{dist.input}" required="true">
<f:convertNumber maxFractionDigits="2"/>
<f:validateDoubleRange maximum="10000"/>
</h:inputText>
<h:message for="inDist"/>
<h:outputText value="Convert To:"/>
<h:form>
<h:selectOneRadio value="#{dist.convertTo}" required="true">
<f:selectItem itemValue="km" itemLabel="Kilometer"/>
<f:selectItem itemValue="miles" itemLabel="Miles"/>
</h:selectOneRadio>
</h:form>
<h:form>
<h:commandButton value="Convert" action="blah"/>
</h:form>
</h:panelGrid>
</h:body>
</html>
Blah.xhtml code:
<h:body>
<h:outputText value="#{dist.input}"/>
</h:body>
So I put in 10 in the InputText field in Index.xhtml and press the command button to go to blah.xhtml. The value in blah is still 0.0.
I'm using Tomcat 7 and Eclipse Heilos and created a dynamic web project. I do have all the JSF jars in WEB-INF/libs. I don't understand why the bean properties are not being set. This look exactly like those newbie codes you find in COREJSF examples. Web.xml is using 2.5 for servlet so I shouldn't need a face-config.xml.
Your <h:inputText> is not inside a <h:form> element.
Put the <h:inputText> inside the same <h:form> as the command button:
<h:form>
<h:inputText id="inDist" value="#{dist.input}" required="true">
<f:convertNumber maxFractionDigits="2"/>
<f:validateDoubleRange maximum="10000"/>
</h:inputText>
<h:message for="inDist"/>
<h:commandButton value="Convert" action="blah"/>
</h:form>
The same applies to your <h:selectOneRadio>. Put it inside the <h:form> where the commandButton is.
