Im running this code in Eclipse 3.7.1 Indigo and the code when executed as a java application works and inserts into cassandra, but when i run it on the server it does not.
Cassandra is running on its default port as a local host and glasfish is also running on a local host on port 8080.
I think the issue is im not placing the hector jars in the correct place, the hector jars are already added to the buildpath but im not sure if that has added them to the server as well.
Any help would be appreciated as I'm failing to find useful documentation for cassandra.
EDIT: i have added the jar's to the server that was not the problem, issue is still unresolved.

I think you just forgot to add also the slf4j jar.
That should solve the problem.
In fact the stack trace says it cannot find the class org.slf4j.LoggerFactory which is included in the slf4j jar.
This jar is needed for hector, and indeed hector rises the exception.

I tried to use donut chart from primefaces cause I used primefaces but the chart won't working.
So this is my XHTML
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<ui:define name="content">
<div class="chart-donut">
<p:donutChart model="#{bean.donutModel}"/>
</div>
</ui:define>
</ui:composition>
for p:donutChart in my case I cannot use it, I don't know why
and this is my java
import org.apache.poi.ss.usermodel.charts.ChartData;
import org.primefaces.model.chart.DonutChartModel;
import javax.annotation.PostConstruct;
import java.util.ArrayList;
import java.util.List;
public class Bean {
private DonutChartModel donutModel;
#PostConstruct
public void init() {
donutModel = new DonutChartModel();
ChartData data = new ChartData();
DonutChartDataSet dataSet = new DonutChartDataSet();
List<Number> values = new ArrayList<>();
values.add(300);
values.add(50);
values.add(100);
dataSet.setData(values);
List<String> bgColors = new ArrayList<>();
bgColors.add("rgb(255, 99, 132)");
bgColors.add("rgb(54, 162, 235)");
bgColors.add("rgb(255, 205, 86)");
dataSet.setBackgroundColor(bgColors);
data.addChartDataSet(dataSet);
List<String> labels = new ArrayList<>();
labels.add("Red");
labels.add("Blue");
labels.add("Yellow");
data.setLabels(labels);
donutModel.setData(data);
}
public DonutChartModel getDonutModel() {
return donutModel;
}
}
and I use the same code like on primefaces documentation. I just want use the chart :(
The problem is the import for DonutChartModel. You're picking up the older version used for p:chart components. For the Charts.js based components the correct package name is:
org.primefaces.model.charts.donut.DonutChartModel
Slightly off topic, the bean also needs annotating. e.g. #Named and #RequestScoped.
I've created a custom Talend component, which at certain step connects to an external Http service. For that, I'm using org.apache.commons.httpclient through javajet imports. I've seen the modules already exist in the Modules view. Nevertheless, when running a job the console outputs:

I've added the following to my Component Descriptor file:

</IMPORTS>
Now, in the modules view I'm able to see the following:
Sadly, the component outputs the same errors.
EDIT 3
After removing the imports and using fully qualified names, as suggested by #Balazs Gunics, the code seems to be generated. Nevertheless, some other errors related to commons-httpclient arise at running time:

So in the begin.javajet code of yours the following code will only import these libraries for the code generation itself. But you need them to the generated code.
Generating java using java makes it hard to oversee this.
<%# jet
imports="
org.apache.commons.httpclient.*
org.apache.commons.httpclient.methods.*
org.apache.commons.httpclient.params.HttpMethodParams
So what you need is to have these imports added to the generated code. Well that is not really possible :( https://www.talendforge.org/forum/viewtopic.php?id=3670 To do that you need to modify the xml descriptor for your component.
So your imports are right. All you have to do is make sure you use the fully qualified names. I.e.: This piece of code:
System.out.println("I am the begin section");
HttpClient client = new HttpClient();
PostMethod method = new PostMethod(<%=authEndpoint%>);
Have to be rewritten to look like this:
System.out.println("I am the begin section");
org.apache.commons.httpclient.HttpClient client =
new org.apache.commons.httpclient.HttpClient();
org.apache.commons.httpclient.methods.PostMethod method =
new org.apache.commons.httpclient.methods.PostMethod(<%=authEndpoint%>);
Yes, it would be way more elegant if we could import the classes and use them.
I'm trying to inject a service into the component via #Reference annotation in Adobe CQ5, but after deployment it always returns null to me instead of service instance.
#Component(immediate = true)
#Service(value = GoodbyeWorldService.class)
public class GoodbyeWorldService {
#Reference
protected Scheduler scheduler;
private final static Logger LOGGER = LoggerFactory.getLogger(GoodbyeWorldService.class);
public void get() {
LOGGER.info("Scheduler is " + this.scheduler);
}
}
The JSP:
<%# include file="/apps/cqblueprints-example/components/global.jspx" %>
<jsp:directive.page contentType="text/html" pageEncoding="UTF-8"/>
<jsp:useBean id="goodbye" class="com.cqblueprints.example.services.GoodbyeWorldService" scope="page" />
<% goodbye.get(); %>
In the log I get:
2014-04-02 12:24:09.999 INFO [com.cqblueprints.example.services.GoodbyeWorldService] Scheduler is null
I've tested other simple print methods from this bean. They are working like charm.
What am I missing?
In order to have #Reference fields injected by the OSGi, you can't treat your service as a Java bean. Use SlingScriptHelper available as the sling object in the JSP files to get the service in a proper way:
<% GoodbyeWorldService service = sling.getService(GoodbyeWorldService.class); %>
<%= service.get() %>
Full example:
<%#page session="false" import="your.package.GoodbyeWorldService"
%><%#taglib prefix="sling" uri="http://sling.apache.org/taglibs/sling/1.0"
%><sling:defineObjects/><%
GoodbyeWorldService service = sling.getService(GoodbyeWorldService.class);
%><%= service.get() %>
The problem is solved! I have just updated the version of maven-scr-plugin from 1.7.4 to 1.9.0 and it started to work! Now I am retrieving my instances via #Reference annotations and I see my service in "Services" and "Components" tabs in Felix OSGi Console. Thanks to all who replied here!
I have tried the following jsp file in both IDEs. It is working good in NetBeans, but it is not working in Eclipse. The program is to get the time from a NTP server.

When i run this in eclipse I get as

Why is it so?
What should I do to make it run on Eclipse?
Worked for me:
"Right click on your project and choose Properties (it's at the bottom...probably). Deployment Assembly is one of the pages. If the jar with the NTP classes is not in WebContent/WEB-INF/lib or otherwise on the server, make sure it is on this page."

I'm using iText library to work with Acrobat Forms. The servlet compiled without any errors. I imported the external jar files of iText. After compiling, i packaged and prepared an executable .war file (Main.war) and pasted it in the deploy folder of jboss. However, on executing, i get a ClassNotFoundException Error.

Sameer
Looks like a DocumentException would be thrown, but the corresponding class can not be found by JBoss.
Are you sure that the iText .jar gets packaged with your webapp? Maybe have a look at the .WAR file you're deploying and check if the iText library is in there...
If not (or you don't want to) make sure to put it in the JBoss' lib folder. in /jboss-as/lib/ or /jboss-as/server/default/lib/.
Edit:
Your JAR should end up having a structure that looks about like this
.
|-- index.html
|-- META-INF
| `-- MANIFEST.MF
|
`-- WEB-INF
|-- classes
| `-- <your code is here>
|
`-- lib
`-- <here are your packaged .jar files>
[Mind, this is simplified and does not show all the files...]
