Opening an InputStream from a SocketConnection, throws Exception

I ve this method:
public void process()throws IOException{
InputStream is=null;
//sc, is an instance of a SocketConnection
is = sc.openInputStream();
//read until it founds the end
String xmlStr=readInputStream(is);
resMsg= parse(xmlStr);
is.close();
It throws the IOException exception that: there are no more inputs streams available... in the line: sc.openInputStream();
what can be happening?

Using sql bulk copy throwing exception -The given value of type String from the data source cannot be converted to type int of the specified target column

Hi All,
I am reading notepads files and inserting data in sql tables from the notepad-
while performing sql bulk copy on this line it throws exception - "bulkcopy.WriteToServer(dt); -"data type related(mentioned in subject )".
Please go through my logic and tell me what to change to avoid this error -
public void Main()
Dts.TaskResult = (int)ScriptResults.Success;
string[] filePaths = Directory.GetFiles(@"C:\Users\jainruc\Desktop\Sudhanshu\master_db\Archive\test\content_insert\");
for (int k = 0; k < filePaths.Length; k++)
string[] lines = System.IO.File.ReadAllLines(filePaths[k]);
//table name needs to extract after = sign
string[] pathArr = filePaths[0].Split('\\');
string tablename = pathArr[9].Split('.')[0];
DataTable dt = new DataTable(tablename);
|
string[] arrColumns = lines[1].Split(new char[] { '|' });
foreach (string col in arrColumns)
dt.Columns.Add(col);
for (int i = 2; i < lines.Length; i++)
string[] columnsvals = lines[i].Split(new char[] { '|' });
DataRow dr = dt.NewRow();
for (int j = 0; j < columnsvals.Length; j++)
//Console.Write(columnsvals[j]);
if (string.IsNullOrEmpty(columnsvals[j]))
dr[j] = DBNull.Value;
else
dr[j] = columnsvals[j];
dt.Rows.Add(dr);
SqlConnection conn = new SqlConnection();
conn.ConnectionString = "Data Source=UI3DATS009X;" + "Initial Catalog=BHI_CSP_DB;" + "User Id=sa;" + "Password=3pp$erv1ce$4";
conn.Open();
SqlBulkCopy bulkcopy = new SqlBulkCopy(conn);
bulkcopy.DestinationTableName = dt.TableName;
bulkcopy.WriteToServer(dt);
conn.Close();
Issue 1:-
I am reading notepad: getting all column and values in my data table now while inserting for date and time or integer field i need to do explicit conversion how to write for specific column before bulkcopy.WriteToServer(dt);
Issue 2:- Notepad does not contains all columns nor in specific sequence in that case i can add few column ehich i am doing now but the issue is now data table will add my columns + notepad columns and while inserting how to assign in perticular colums?
sudhanshu sharma Do good and cast it into river :)

Hi,
I think you'll have to do an explicit column mapping if they are not in exact sequence in both source and destination.
Have a look at this link:
https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlbulkcopycolumnmapping(v=vs.110).aspx
Good Luck!
Kaur.

Throw exceptions from threads?

CyaYou can't throw checked exceptions, because obviously the code responsible for invoking the run() method wouldn't know what to do with it, and you wouldn't be the one to catch them. You can however throw unchecked exceptions (such as those based on RuntimeException).

I have the interactive student mathematics CD for the Cambridge IGCSE Mathematics (0607) Extended from Haese & Harris Publications that requires Adobe Reader and includes a 'Self-help Tutor". I can open all the features using Adobe Reader except the Self-Tutor. I get a pop-up message saying that: I require an app to open "26Unitary Method.app". I can find no mention of this app online so can someone please help me?
Thank you.

Thank you for the prompt reply. The CD says that it needs Adobe Reader (and it does read the 'Text book'), but it is not opening the interactive elements. Great!
I am doing as you suggest and contacting Haese directly. Again, many thanks.

How to throws exception from subprocess?

Hi,
I use subprocess in my process and I need throws exception from subprocess to my main process.
Thanks for help.
Jakub

The only to throw an exception from a sub process is by leveraging the Exception event (from the event view).
You need to throw the exception, by dragging the Exception event and choose Throw into your subprocess. Then you need to add an exception "catcher" in the parent process to catch the Exception.

Project Pro hangs while opening a schedule from Project 2010 server.

Hi,
We have an issue with opening a schedule from Project server 2010. Project client is not responding. when we try to open schedule in PWA. I am getting unable to open file do you want to open in default view. No matter which view I choose keep getting the
same error. The only view i can see resource view however it will not let me edit. I did notice Project Manager had entered resource names first, last name format which do not exist in our resource pool. We can open other schedule except this particular
one.
Thank you

Obviously, my first thoughts are that this plan is corrupted in some fashion. Entering Resource names differentluy should not cause this issue, they will just not be recognized as Enterprise Resources by the system.
Are you experiencing the issue if you try to open the schedule from PWA? If you are able to open from PWA, try publishing it from PWA and see if it throws any errors.
Also, how about trying it from a different machine?
And finally, it might be worthwhile to check if you have the latest Client Update for Project installed (or atleast matching with the server).
If none fof these work,
a) you could try restoring it from Archive Database (assuming you have a daily schedule backup running)
b) If you are able to open it from another machine, you could use the "Save for sharing" feature to try and resolve any corruption with the schedule itself.

Programmatically adding chart to a report throws exception

programmatically adding chart to a report throws exception "chart condition fields are not valid".
Configuration:
I am using CR4E to create web application, I've added RAS jars (rasapp.jar, rascore.jar, reporttemplate.jar, serialization.jar) to this web application. For designing reports i am using Crystal Reports 2008.
Code:
<%
// Get the previously opened report from the session.
ReportClientDocument reportClientDocument =
     (ReportClientDocument)session.getAttribute("ReportClientDocument");
System.out.println(reportClientDocument.getReportDocument().getName());
// Try to get the report's DataDefinition object.
IDataDefinition dataDefinition;
try
     dataDefinition = reportClientDocument.getDataDefController().getDataDefinition();
// If the DataDefinition object can not be retrieved, redirect the user to an error page.
catch (Exception e)
     System.out.println("With error1");
    return;
// Create a new ChartDefinition object and set its type to ChartType.group.
ChartDefinition chartDefinition = new ChartDefinition();
chartDefinition.setChartType(ChartType.group);
Get the conditional field of the report's first group. Set this conditional
field for the ChartDefinition object using the setConditonalFields method. Notice
that the conditional field is first placed in a Fields collection because the
setConditionalFields method takes a Fields object as an argument.
Fields conditionFields = new Fields();
if (!dataDefinition.getGroups().isEmpty())
     IField field = dataDefinition.getGroups().getGroup(0).getConditionField();
     System.out.println("Condition field name ->" + field.getLongName(Locale.ENGLISH));
     conditionFields.addElement(field);
chartDefinition.setConditionFields(conditionFields);
//Get the summary field name from the form on the previous page.
String summaryFieldName = URLDecoder.decode(request.getParameter("summaryField"));
System.out.println("Summary field name ->" + summaryFieldName);
Loop through all of the report's summary fields until the one matching the name
above is found. Set this summary field for the ChartDefinition object using the
setDataFields method. Notice that the summary field is first placed in a Fields
collection because the setDataFields method takes a Fields object as an argument.
Fields dataFields = new Fields();
for (int i = 0; i < dataDefinition.getSummaryFields().size(); i++)
    IField summaryField = dataDefinition.getSummaryFields().getField(i);
     if (summaryField.getLongName(Locale.ENGLISH).equals(summaryFieldName))
          System.out.println("Adding data field ->" + summaryFieldName);
          dataFields.addElement(summaryField);
chartDefinition.setDataFields(dataFields);
Create a new ChartObject to represent the chart that will be added. Set the
ChartDefinition property of the ChartObject using the ChartDefinition object created
above.
ChartObject chartObject = new ChartObject();
chartObject.setChartDefinition(chartDefinition);
Get the chart type, chart placement, and chart title strings from the form on the
previous page. If no chart title was chosen, create a generic title.
String chartTypeString = request.getParameter("type");
String chartPlacementString = request.getParameter("placement");
String chartTitle = request.getParameter("title");
System.out.println("chartTypeString ->"+ chartTypeString + "<-chartPlacementString->" + chartPlacementString + "<-chartTitle->"+chartTitle);
if (chartTitle.equals(""))
     chartTitle = "untitled";
Create a ChartStyleType object and a AreaSectionKind object based on the
the chartTypeString and chartPlacementString retrieved above. In this example
possible chart types are bar chart and pie chart. Possible chart placements
are header and footer.
ChartStyleType chartStyleType = ChartStyleType.from_string(chartTypeString);
AreaSectionKind chartPlacement = AreaSectionKind.from_string(chartPlacementString);
// Set the chart type, chart placement, and chart title for the chart.
chartObject.getChartStyle().setType(chartStyleType);
chartObject.setChartReportArea(chartPlacement);
chartObject.getChartStyle().getTextOptions().setTitle(chartTitle);
// Set the width, height, and top for the chart.
chartObject.setHeight(5000);
chartObject.setWidth(5000);
chartObject.setTop(1000);
Get a ReportDefController object that can be used to modify the report's definition.
ReportDefController reportDefController;
try
     reportDefController = reportClientDocument.getReportDefController();
catch (Exception e)
     System.out.println("With Error2");
     return;
*Create a Section object that represents the section that will hold the chart.
If the chart placement was set header, get the header section, otherwise, if the
chart placement was set to footer, get the footer section.
Section chartSection = null;
if (chartPlacement.equals(AreaSectionKind.reportHeader))
     IArea reportHeaderArea =
          reportDefController.getReportDefinition().getReportHeaderArea();
     chartSection = (Section)reportHeaderArea.getSections().getSection(0);
else if (chartPlacement.equals(AreaSectionKind.reportFooter))
     IArea reportFooterArea =
          reportDefController.getReportDefinition().getReportFooterArea();
     chartSection = (Section)reportFooterArea.getSections().getSection(0);
Add the chart to the section using the ReportDefController object.
reportDefController.getReportObjectController().add(chartObject, chartSection, 1);
// Save the changes and close the report.
reportClientDocument.save();
reportClientDocument.close();
session.removeAttribute("ReportClientDocument");

Throws Exception - a newcomer...

I have written a small amount of code that takes information from a text file and displays it in a GUI (swing) - this is called my RasterDisplay class. However, I am now creating another part of the GUI which will have a button that makes a new RasterDisplay. However, when I try and call my RasterDisplay constructor from within my actionPerformed method (see below) It tells me I have an "unhandled Exception type Exception". I can't throw Exception in the actionPerformed method so how do I get this method to work? Any help would be greatly appreciated - I am a total newcomer to Java and can't make head nor tail of related topics in all the forums...
Cheers!

SQL query throwing Exception.

Hi,
i am facing a problem while using the date as search criteria. In the JDO class the field type is of java.util.Date. The search is working in the local environment whose local date settings as M/d/YYYY(windows 2003 , english version).The search is not working in the chines OS environment , where the local date setting is YYYY-M-d. In the chinese enviroment , if we alter the session NLS settings in toad, we could able to execute the query.
we are using kodo-2.5.8
SELECT t0.JDO_ID, t0.JDO_CLASS, t0.BAD_NAMES, t0.CONCAT_NAME, t0.DDATE, t0.FIRST_NAME, t0.LAST_NAME, t0.MAX_SCN, t0.NAME,
t0.NATURALID, t0.PARTYID, t0.PHONE, t0.ROLE FROM PARTY_VBO t0 WHERE (t0.ROLE LIKE '%ICR%' AND t0.DDATE = '17-APR-1974' AND ROWNUM <= 25) AND
t0.JDO_CLASS = 2 ORDER BY t0.PARTYID ASC)
This Query is throwing ORA-01843.
From where the session opened by the java in oracle will take the data format?

Plaese help.
One of my sql query is throwing exception during
execution. I do not know which one (there are several
of them). Is there a way to display or extract the
last query from SQLException class.
Any help will be highly appreciated.
Thanks,
Indrasish.No there is not. You should do some debugging, such as logging something like: "Executing query: SELECT blahblahblah" - then execute the query, then log something like: "Query completed". Then find in your log which one didn't complete.

Java Does Not Throw Exception When Writing To Read-Only Files

I have noticed that when I try to write to a read-only file in a window environment, Java does not throw an IOExcpetion, it just dosn't write to the file.
I am writing an FTP server and here is the code:
     public static long copyStream(InputStream in, OutputStream out)throws IOException
          IOException exception = null;
          long copied = 0;
          try
               byte buffer[] = new byte[1024];
               int read;
               while((read = in.read(buffer)) != -1)
                    out.write(buffer, 0, read);
                    copied += read;
          catch(IOException e)
               //ensures that the streams are closed.
               exception = e;
          try
               in.close();//ensures output stream gets closed, even if there is an
               //excption here.
          catch(IOException e){exception = e;}
          out.close();//try to close output.
          if(exception != null)
               //exception is not null, an exception has occured.
               //rethrow exception.
               throw exception;
          return copied;//all ok, return bytes copied.
     }Is this a bug in JAVA VM? Is so, how should I report it?

Finding hard and soft open file limits from within jvm in linux

Hi All,
I have a problem where I need to find out the hard and soft open file limits for the process in linux from within a java program. When I execute ulimit from the terminal it gives separate values for hard and soft open file limits.
From shell if I run the command then the output is given below:
$ ulimit -n
1024
$ ulimit -Hn
4096
The java program is given below:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import java.io.StringWriter;
import java.io.Writer;
public class LinuxInteractor {
public static int executeCommand(String command, boolean waitForResponse, OutputHandler handler) {
int shellExitStatus = -1;
ProcessBuilder pb = new ProcessBuilder("bash", "-c", command);
pb.redirectErrorStream(true);
try {
Process shell = pb.start();
if (waitForResponse) {
// To capture output from the shell
InputStream shellIn = shell.getInputStream();
// Wait for the shell to finish and get the return code
shellExitStatus = shell.waitFor();
convertStreamToStr(shellIn, handler);
shellIn.close();
catch (IOException e) {
System.out
.println("Error occured while executing Linux command. Error Description: "
+ e.getMessage());
catch (InterruptedException e) {
System.out
.println("Error occured while executing Linux command. Error Description: "
+ e.getMessage());
return shellExitStatus;
public static String convertStreamToStr(InputStream is, OutputHandler handler) throws IOException {
if (is != null) {
Writer writer = new StringWriter();
char[] buffer = new char[1024];
try {
Reader reader = new BufferedReader(new InputStreamReader(is,
"UTF-8"));
int n;
while ((n = reader.read(buffer)) != -1) {
String output = new String(buffer, 0, n);
writer.write(buffer, 0, n);
if(handler != null)
handler.execute(output);
} finally {
is.close();
return writer.toString();
} else {
return "";
public abstract static class OutputHandler {
public abstract void execute(String str);
public static void main(String[] args) {
OutputHandler handler = new OutputHandler() {
@Override
public void execute(String str) {
System.out.println(str);
System.out.print("ulimit -n : ");
LinuxInteractor.executeCommand("ulimit -n", true, handler);
System.out.print("ulimit -Hn : ");
LinuxInteractor.executeCommand("ulimit -Hn", true, handler);
If I run this program the output is given below:
$ java LinuxInteractor
ulimit -n : 4096
ulimit -Hn : 4096
I have used ubuntu 12.04, Groovy Version: 1.8.4 JVM: 1.6.0_29 for this execution.
Please help me in understanding this behavior and how do I get a correct result from withing the java program.

As mentioned in one of the earlier responses:
@OP this is not a Java question. I suggest you take it elsewhere, i.e. to a Unix or Linux forum.You posted this to a Java programming forum.
It is not a Java programming inquiry.

Additionally, you have answered your own question.
Don't bother posting it to one of the OS forums. It will get deleted as a duplicate cross-post.

Open and read from text file into a text box for Windows Store

I wish to open and read from a text file into a text box in C# for the Windows Store using VS Express 2012 for Windows 8.
Can anyone point me to sample code and tutorials specifically for Windows Store using C#.
Is it possible to add a Text file in Windows Store. This option only seems to be available in Visual C#.
Thanks
Wendel

This is a simple sample for Read/Load Text file from IsolateStorage and Read file from InstalledLocation (this folder only can be read)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Windows.Storage;
using System.IO;
namespace TextFileDemo
public class TextFileHelper
async public static Task<bool> SaveTextFileToIsolateStorageAsync(string filename, string data)
byte[] fileBytes = System.Text.Encoding.UTF8.GetBytes(data);
StorageFolder local = Windows.Storage.ApplicationData.Current.LocalFolder;
var file = await local.CreateFileAsync(filename, CreationCollisionOption.ReplaceExisting);
try
using (var s = await file.OpenStreamForWriteAsync())
s.Write(fileBytes, 0, fileBytes.Length);
return true;
catch
return false;
async public static Task<string> LoadTextFileFormIsolateStorageAsync(string filename)
StorageFolder local = Windows.Storage.ApplicationData.Current.LocalFolder;
string returnvalue = string.Empty;
try
var file = await local.OpenStreamForReadAsync(filename);
using (StreamReader streamReader = new StreamReader(file))
returnvalue = streamReader.ReadToEnd();
catch (Exception ex)
// do somthing when exception
return returnvalue;
async public static Task<string> LoadTextFileFormInstalledLocationAsync(string filename)
StorageFolder local = Windows.ApplicationModel.Package.Current.InstalledLocation;
string returnvalue = string.Empty;
try
var file = await local.OpenStreamForReadAsync(filename);
using (StreamReader streamReader = new StreamReader(file))
returnvalue = streamReader.ReadToEnd();
catch (Exception ex)
// do somthing when exception
return returnvalue;
show how to use it as below
async private void Button_Click(object sender, RoutedEventArgs e)
string txt =await TextFileHelper.LoadTextFileFormInstalledLocationAsync("TextFile1.txt");
Debug.WriteLine(txt);

Opening a socket from an applet

I tried to open a socket from an applet to a server on a remote computer and I've got a refusal message.
When I try it on a server in the local machine, it works.
What could be the problem ?
P.S. : when I open the socket from an application in the Java environment, to the same remote server it works ok.

this is part of the security system built into java and Applets
unless you sign an Applet it cannot do many "dangerous" things, like..
access the loacl file system
connect to any server except the server that it came from

PROBLEM while using URL in order to open a file from a servlet

Hi,
I am having a problem while trying to open a file from my servlet by using URL connection. Following is my code sample. what happens is when I first run my project it opens the file but after that when I rerun it again and again it sometimes opens it and sometimes not. if it can't open it it gives an error saying "the file is damaged and couldn't be repaired". I don't get any exceptions. if you guys can help me I will appreciate it so much... thanks.
here is my code :
URL url = new URL("http://demobcs.ibm.com:81/test.pdf");
resp.setContentType(getContentType("http://demobcs.ibm.com:81/test.pdf"));
          ServletOutputStream sos = null;
          BufferedInputStream bis = null;
          try {
               sos = resp.getOutputStream();
          } catch (Exception e) {
               System.out.println("exception !!!!");
               e.printStackTrace();
          System.out.println("burada2");
          try {
               byte[] bytes = new byte[4096];
               //bis = new BufferedInputStream(conn.getInputStream());
               DataInputStream in = new DataInputStream(url.openStream());
               //DataInputStream in = new DataInputStream(conn.getInputStream());
               bis = new BufferedInputStream(in);
               int j;
               while ((j = bis.read(bytes, 0, 4096)) != -1) {
                    try {
                         sos.write(bytes, 0, 4096);
                         System.out.println("file is being read ...:");
                    } catch (Exception e) {
                         e.printStackTrace();
               in.close();
               bis.close();
               //sos.close();
          } catch (Exception e) {
               System.out.println("exception :"+e.toString());
               e.printStackTrace();
          }

You are writing (<filesize> mod 4096) bytes of crap at the end of the file. Use your variable j instead for the number of bytes to write in your loop.
