I'm trying to export data from a database into an Excelsheet using the JExcel Api when a specific servlet is called, but when starting Tomcat I get multiple exceptions. Here's the error message as given by eclipse:

The method writeTestFile() from the WriteExcel class works fine when tested in a local standalone project.
The servlet itself also works when the method writeTestFile() is not called.
Could someone clarify why I'm getting the exceptions?
Also is there a fix or workaround?
Try this: double click on the server, click on "Open launch configuration", go to Classpath tab and under User Entries add the jar.

I don't have much experience with Java and I need a little help with the following issue.
I’m trying to make a Birt Java Servlet in order to generate PDF files based on a given input (XML in this case). I’m using Tomcat 7.0 for that I was able to create blank PDF files with this code (I’ve commented out a lot of lines in order to get Tomcat started).
public class Servlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* #see HttpServlet#HttpServlet()
*/
public Servlet() {
super();
// TODO Auto-generated constructor stub
}
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
//get report name and launch the engine
resp.setContentType( "application/pdf" );
resp.setHeader ("Content-Disposition","inline; filename=test.pdf");
String reportName = req.getParameter("ReportName");
ServletContext sc = req.getSession().getServletContext();
}
/**
* #see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}}
But when I try with the complete code that is:
public class Servlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* #see HttpServlet#HttpServlet()
*/
private IReportEngine birtReportEngine = null;
protected static Logger logger = Logger.getLogger( "org.eclipse.birt" );
public Servlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* #see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
//get report name and launch the engine
resp.setContentType( "application/pdf" );
resp.setHeader ("Content-Disposition","inline; filename=test.pdf");
String reportName = req.getParameter("ReportName");
ServletContext sc = req.getSession().getServletContext();
this.birtReportEngine = BirtEngine.getBirtEngine(sc);
IReportRunnable design;
try
{
//Open report design
design = birtReportEngine.openReportDesign( sc.getRealPath("/Reports")+"/"+reportName );
//create task to run and render report
IRunAndRenderTask task = birtReportEngine.createRunAndRenderTask( design );
task.getAppContext().put("BIRT_VIEWER_HTTPSERVLET_REQUEST", req );
PDFRenderOption options = new PDFRenderOption();
options.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_PDF);
options.setOutputStream(resp.getOutputStream());
task.setRenderOption(options);
//run report
task.run();
task.close();
}catch (Exception e){
e.printStackTrace();
throw new ServletException( e );
}
}
/**
* #see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}}
the Tomcat Server (Version 7.0) doesn’t start anymore and the following info is logged to the console:

If I delete code for creating MarkLogic client everything works fine.

It looks like you are missing some jars while deploying your application.
Please make sure you have your build.xml configuration set so it deploys all of marklogic jars you need.
<target name="war" depends="compile">
<delete file="${war.name}"/>
<war warfile="${dist.dir}/${war.name}" webxml="${webinf.dir}/web.xml">
<classes dir="${bin.dir}">
<exclude name="**/client/*.class"/>
<include name="**/*.class"/>
</classes>
<lib dir="${lib.dir}">

<webinf dir="${webinf.dir}">

i don't know if i made the WeakHashMap transient will that affect the spring view scope or what ?
please advise how to solve this issue.
You get a java.io.NotSerializableException with the message java.util.WeakHashMap meaning that the WeakHashMap is not serializable.
From the stack trace one can see that Tomcat is trying to serialize a session (StandardSession.writeObjectData). That suggests that some attribute of your session is a WeakHashMap.
If you want your session to be serializable (which is useful for clustering and saving session data between server restarts), then you need to get rid of that (or wrap it in another object that handles the serialization correctly).
Either turn of session serialization, if you don't need it, or find out which attribute is the WeakHashMap (simply iterate over all of them and print the names of all WeakHashMap values).
Did anyone encountered this exception while using Jena in Java Web Application... Please Kindly help me ..

That means that tomcat can't find the Jena libraries. Make sure you have all the right jars in the right place.
You need to copy each of the *.jar files from $JENA/lib (where $JENA is the directory you installed your local installation of Jena into) to the WEB-INF/lib directory of your servlet application.
just copy the jena jars declared on the build path project to the lib directory of tomcat, in my case it is located at
C:\Apache Software Foundation\Tomcat 6.0\lib
