The log does not reflect the cause the loading failure.
The issue is you have wrong path:
String path = "file:///assets/";
Which should be:
String path = "file:///android_asset/";

I am getting this as default folder F:\jboss-4.2.3.GA-jdk6\jboss-4.2.3.GA\bin\ please help i am new to this
Your problem is here:
String root = getServletContext().getRealPath("/");
you are setting the upload path to the containers path, not a default path but the place where the server started from. You can make the upload path anything you want it to be, it depends on your needs and configuration.
You could create a system property with the directory of your choice, you could set it as a dynamic property in a JBoss configuration file (not sure what that would be for JBoss4).
UploadEvent only sent to Fileupload component when the file is uploaded, but I would like to be noticed when the file start to upload. Is there anyway for doing this ?
Example:-
index.zul
<?page title="Auto Generated index.zul"?>
<window title="Drop here" border="normal" width="100%" height="100%"

onUpload="#command('doUpload')">
</dropupload>
<button label="Download" onClick="#command('doDownload')"></button>
</window>
DropFileViewModel.java

I have two AutoCompleteTextView controls on the same page: ACTV1 and ACTV2 and only one (ACTV1 ) is showing suggestions from my database . For each databinding action I've made a java class separetely: ACTV1.java and ACTV2.java.
But if I am adding an intent filter (MAIN, LAUNCHER) in my manifest file for ACTV2.java class and setting in run configuration ACTV2.java as Launch Action then I won't get suggestions anymore for ACTV1 control but this time I'll get suggestions for ACTV2 control.
The two java classes are identically just that differ the name of some constants/controls name.

this is my code, it seems right to me! i don't know why it keeps saying this:
"Cannot instantiate the type Iterator"
this is the servlet:
package uges.servlets;
import jess.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.Iterator;
public class Catalog extends BaseServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
checkInitialized();
try {
String customerId =
(String) request.getParameter("customerId");
if (customerId == null || customerId.length() == 0) {
dispatch(request, response, "/index.html");
return;
}
request.getSession().invalidate();
HttpSession session = request.getSession();
session.setAttribute("customerId", customerId);
session.setAttribute("orderNumber",
String.valueOf(getNewOrderNumber()));
ServletContext servletContext = getServletContext();
Rete engine = (Rete) servletContext.getAttribute("engine");
Iterator result =
engine.runQuery("all-products", new ValueVector());
request.setAttribute("queryResult", result);
} catch (JessException je) {
throw new ServletException(je);
}
dispatch(request, response, "/catalog.jsp");
}
this is the dispatch method, it 's in a servlet called BaseServlet:
protected void dispatch(HttpServletRequest request,
HttpServletResponse response,
String page)
throws IOException, ServletException {
ServletContext servletContext = getServletContext();
RequestDispatcher dispatcher =
servletContext.getRequestDispatcher(page);
dispatcher.forward(request, response);
}
and this the JSP code:
<HTML>
<%# page import="jess.*" %>
<jsp:useBean id="queryResult" class="java.util.Iterator" scope="request"/>
the error is about the java.util.Iterator in the class type of useBean tag!
the exception says : The value for the useBean class attribute java.util.Iterator is invalid
any help please ..
Thanks in advance!
java.util.Iterator is an Interface, not a Class. You want
<jsp:useBean id="queryResult" type="java.util.Iterator" scope="request"/>
To confirm this I used the following test code:
package org.apache.markt.so;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
#WebServlet("/Q001Servlet")
public class Q001Servlet extends HttpServlet {
private static final long serialVersionUID = 1L;
#Override
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
List<String> list = new ArrayList<String>();
list.add("item1");
list.add("item2");
request.setAttribute("list", list.iterator());
RequestDispatcher rd = request.getRequestDispatcher("/so/q001.jsp");
rd.forward(request, response);
}
}
With the following /so/q001.jsp
<html>
<jsp:useBean id="list" type="java.util.Iterator" scope="request" />
<body>
<p><%=list.next()%></p>
</body>
</html>
This was using HEAD from the latest development branch but you'll see the same results with the latest Tomcat 7 release.
Here is a JSP that demonstrates my idea.
<%# page import="java.util.*" %>
<%#taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%
//for testing
List<String> engineList = new ArrayList<String>();
engineList.add("zero");
engineList.add("one");
engineList.add("two");
engineList.add("three");
Iterator<String> result = engineList.iterator();
// create a list from engine result
List<String> list = new ArrayList<String>();
while(result.hasNext())list.add(result.next());
request.setAttribute("list", list);
%>
<html>
<body>
Complete list is${list}
The first item is ${list[0]}.
The second item is ${list[1]}.
If you don't know how many items there are in result, then use JSTL
<c:forEach var="item" items="${list}" >
${item}
</c:forEach>
</body>
</html>

I think this is a problem related to the emulator and not the physical device.
I used this code and I got a bitmap:

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
captureButton = (Button)findViewById(R.id.capture);
captureButton.setOnClickListener(listener);
imageView = (ImageView)findViewById(R.id.image);
destination = new File(Environment.getExternalStorageDirectory(),"image.jpg");
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == REQUEST_IMAGE && resultCode == Activity.RESULT_OK) {
//Bitmap userImage = (Bitmap)data.getExtras().get("data");
try {
FileInputStream in = new FileInputStream(destination);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 10; //Downsample 10x
Bitmap userImage = BitmapFactory.decodeStream(in, null, options);
imageView.setImageBitmap(userImage);
} catch (Exception e) {
e.printStackTrace();
}
}
}
private View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
//Add extra to save full-image somewhere
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(destination));
Toast.makeText(JMABarcodeScannerActivity.this, Uri.fromFile(destination).toString(), Toast.LENGTH_SHORT).show();
startActivityForResult(intent, REQUEST_IMAGE);
}
};
}
