What is wrong? I am not getting the problem where I am going to wrong .Thanks for the help in advanced.
I think the issue is in the
String filePath = "D:\\uploadImage";
File destFilePath = new File(filePath);
you are declaring a direction as a file, but you need a filename to write to a specific file.
for example try:
String filePath = "D:\\uploadImage";
File destFilePath = new File(filePath+"\\uploadimage.jpg");
The error
java.io.FileNotFoundException: D:\uploadImage (Access is denied)
is quite clear: the file is not found.
To quote from your code:
File destFilePath = new File(filePath);
if (!destFilePath.exists()) {
new File(filePath).mkdirs();
}
FileOutputStream fos = new FileOutputStream(destFilePath);
fos.write(buffer);
In your particular case you are initially creating a directory by calling File#mkdirs() and later trying write to the directory referenced by that File object. This is not legal.
You need to create a file and write to the file instead. For instance, you could use Java SE 7 Files#copy(...). See also How to save uploaded file in JSF.
Thanks brother , I got the answer. at line 1 and line 2 where I am going to wrong. I was not specify the image name (file name)

I'm trying to write to file from a servlet and i'm not really sure if the path i gave in the xml file is wrong or something else
private List<User> getUsersList() throws IOException, ClassNotFoundException{
List<User> users=new ArrayList<User>();
FileInputStream fis=new FileInputStream(f);
ObjectInputStream ois=new ObjectInputStream(fis);
User u;
while(true){
if((u=(User) ois.readObject())==null)
break;
else{
users.add(u);
}
}
ois.close();
return users;
}
that's the method i use to read from file where
private final String usersfile;
private ArrayList<User> users;
private File f;
public UsersService(String filename) throws ClassNotFoundException, IOException {
super();
usersfile=filename;
f=new File(this.usersfile);
if(!f.exists()){
f.createNewFile();
}
users= (ArrayList<User>) this.getUsersList();
}
and the xml param
<context-param>
<param-name>userslist</param-name>
<param-value>/users.txt</param-value>
</context-param>
and that's the exception

Please anybody help me as i don't know how to fix this issue and probably i may be doing some silly mistake but i can't figure it out. Please help me . i will be very thankful to you!
You can't write in the client File System like that; in your case, your server is in your machine, but don't get fooled, it's a server path, not a client one. You need to write on the response.
You can't use both Struts2 result and writing in the OutputStream together: when manually forging the response, you must bypass the framework convention, and return the result by yourself. The correct result for this case is is Action.NONE:
<action name="Download" class="com.cdac.action.DownloadAction" />
public String execute(){
/*
do your stuff
*/
return NONE;
}
You're lucky, here is a kick off example I've written long time ago, explaining the whole thing (including the need to deal with duplicate filenames in the same ZIP).
Also try using Content-Length properly (to let the browser draw a realistic progress-bar).
I'm trying to generate pdf via button but my problem is this method
JasperRunManager.runReportToPdfStream(reportStream,servletOutputStream, new HashMap<Object, Object>(), resultSetDataSource);
it is not supporting Hashmap it gives following error
The method runReportToPdfStream(InputStream, OutputStream, Map<String,Object>, Connection) in the type JasperRunManager is
not applicable for the arguments (InputStream, ServletOutputStream, HashMap<Object,Object>, JRResultSetDataSource)
it Supports String parameter like Hashmap<String,Object> while generating pdf it gives following error

Solution is I Removed Run Report pdf stream and used method as exportReport to pdf Stream
JasperRunManager.runReportToPdfStream(reportStream,servletOutputStream, new HashMap<Object, Object>(), resultSetDataSource);
Coding:-
InputStream reportStream = getServletConfig().getServletContext().getResourceAsStream("WEB-INF/HR/Jasp.jrxml");
ByteArrayOutputStream baos =new ByteArrayOutputStream();
response.setContentType("application/pdf");
JasperDesign design = JRXmlLoader.load(reportStream);
JasperReport report = JasperCompileManager.compileReport(design);
JRResultSetDataSource jasperReports = new JRResultSetDataSource(rs);
JasperPrint print = JasperFillManager.fillReport(report, new HashMap(), jasperReports);
net.sf.jasperreports.engine.JasperExportManager.exportReportToPdfStream(print,baos);
response.setContentLength(baos.size());
ServletOutputStream out1 = response.getOutputStream();
baos.writeTo(out1);
out1.flush();
rs.close();
st.close();
conn.close();
