<f:param value="#{bean.timeStamp}" name="time" />
</a4j:mediaOutput>My Java Code is
public Part part;
//getters & Setters
public void paint(OutputStream stream, Object data) throws IOException{
InputStream inputStream = null;
try {
inputStream = part.getInputStream();

Is there anything i'm missing. please help me out.

You can upgrade to the latest version where this issue is fixed. Alternatively open your RichFaces jar/zip and find resource-serialization.properties, then add "org.apache.el.lang.VariableMapperImpl" to the whitelist.

Please guide on where i am wrong..

visit http://docs.oracle.com/cd/E17802_01/products/products/servlet/2.5/docs/servlet-2_5-mr2/javax/servlet/ServletContext.html#getRealPath%28java.lang.String%29
use servletContext.getRealPath(path to file);

WebContenct is not deployed on server as it is only for eclipse. so remove Webcontent from the path and give a try.

filePath contains a relative file and you try to load the filePath using a method where absolute files are required.
Try
filePath = servlet.getRealPath("Images/"
+ userForm.getUploadedFile().getFileName());

My guess is that the StringUtils class is not getting access to the file.encoding system property, and becuase of that JVM is not able to properly load the class.
Is my guess right??
I have tried a lot on my own, but unable to get to an answer. I just cannot figure out where the problem lies. Please help me..
Thankyou very much in advance.

Check that the MySQL connector JAR is in the webapp's WEB-INF/lib folder and it actually contains the class (com.mysql.jdbc.StringUtils) that the exception says it cannot load.

Running testng programatically within a Main method?

I've been searching how to run testng programatically, and i'm not quite sure, but you have to create a testng instance and execute the 'run' method within a main method, or a static method..
I've followed an example where a main method is used...but here's the thing...i'm trying to run testng programatically in a jsf application...is it possible to execute a main method in a jsf application?
When i try to create a testng instance in any other non static method, i get a lot of exceptions...when i tried to do it in a main method, it worked...
EDIT:here's what i was trying to do but with no success:
public class ExecTestSuite {
private TestNG myTestNG;
private XmlSuite myXmlSuite;
private List<String> arquivos;
public ExecTestSuite()
{
myTestNG = new TestNG();
files = new ArrayList<String>();
files.add("C:\\Users\\jmartins\\Desktop\\XML.xml");
myTestNG.setTestSuites(files);
}
public void executarSuite(){
this.myTestNG.run();
}
}
Here's what i've got:

The only thing i did, is to create the "ExecTestSuite" instance inside a ManagedBean (i'm working on a jsf project) that's session scoped. When i tried to debug my code, it shows that when the testng instance is created (new comand) the exceptions are raised. But when i tried to create it in a main method, it worked.

BIRT engine exception while running the report in Tomcat server

I have BIRT 4.2 version framework, while running the application from tomcat server i got "org.eclipse.birt.report.engine.api.EngineException: Error happened while running the report."
exception. But it is working fine through RCP application.Coppied the .rptdesign file in the root of the birt folder in Tomcat, and after that jar file has to be copied to the Tomcat webapps/birt/WEB-INF/lib/ directory.
And mt Stacktrace is
