Throwing Exception having multiple arguments in constructor

hi,
I am trying to implement exception handling for a JAVA + C++ module.
In which C++ exception is caught by a Java module.
The c++ code is as follows,
try
///////////===========
} catch (Exception1 &e) {
jclass clazz = jenv->FindClass("test/Exception1Java");
if(clazz)
jenv->ThrowNew(clazz,e.getErrMsg().c_str());
return 0;
} catch (Exception2 &e) {
jclass clazz = jenv->FindClass("test/Exception2");
if(clazz)
jenv->ThrowNew(clazz,e.getErrMsg().c_str());
return 0;
This works perfectly fine.
But I want to pass one more argument as int while throwing the java exception.
jenv->ThrowNew(clazz,e.getErrId(),e.getErrMsg().c_str());
As the jenv->ThrowNew function only take two arguments I am unable to send the error id( int ) to the message.
Is there any alternate to this function or some other approach to throw the java exceptions.

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");

** Throw Exception in BPM - Webservice to JDBC

Hi friends,
I am doing Webservice to JDBC scenario using BPM. I am doing insert data in backend system oracle table by passing inputs from WebService. After insert data in table, JBDC returns the response to web service thru response variable 'insert_count = 1' like this. When I try to insert the same record, that is, employee no as primary key in my table, XI throws an error 'ORA-00001 - unique constraint' in Addtional . We have to pass this information to Web Service. How will we achive this ?
Presently in our BPM design,
1) Exception property of the block as 'Error'.
2) Inside Block, in Sync Send Step (BPM -> JDBC) specified 'Exception/System Error' as 'Error'.
3) Inserted one Exception Handler Brach. In this Brach, inserted one control step. In this step, itself we put a Control Step, the action property of this step is 'Throw Exception'. Here , what we need to set for the 'Exception Property' ..?
Kindly help me friends.

Question about throws exception in interface and realized class

Hi,all
If I define a method In the interface like that-
public void Execute() throws NumberFormatException; In the realized class, I can define this method like that-
public void Execute() throws RuntimeException{
System.out.println("test");
}This is a right realization. But if I manage it to throws Exception or to throws Throwable in the class it leads a error. Why add this restrict only to Exception? What is the purpose of this way?
Greetings and thanks,
Jason

When you say "throws NumberFormatException" you are really saying:
When using classes implementing this interface, you have to be prepared to deal with them throwing a NumberFormatException. Other exceptions won't happen.
When you come to implement it, it might not be possible for it to throw a NumberFormatException, so there's no reason why you should have to lie about that. Code handling it directly will be fine (it doesn't throw a NFE) and code handling it via the interface will be fine (it will handle NFEs, they just don't happen).
If your concrete implementation throws other sorts of exception, such as Exception or IOException, and so on, it's incompatible with code that's manipulating the interface. The interface says "NFEs might get thrown, nothing else will." while your implementation says "IOExceptions might get thrown".
So that explains why you can't use arbitrary exceptions. The special case is RuntimeException. RuntimeExceptions don't have to be caught, and it's expected that they can happen at any time - so there's no point trying to catch and handle them as a general case.
The classic example of a RuntimeException is a NullPointerException. You don't need to declare your method as throwing a NullPointerException even though it might get thrown. And you don't have to add NullPointerException to the throws part of the interface definition, because you already know that the concrete implementation could throw a NPE at any time.
Hope that helps (a little).
I'd recommend reading the API documentation on RuntimeException and Exception to get a clearer insight into this.
Dave.

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!

Java.utils.prefs.Preferences API throws exception on Mac, not Windows

This is a Mac-specific problem. Is it a bug, or am I misusing the java.utils.prefs.Preferences API?
The Preferences flush() API call always throws a BackingStoreException if a system tree preferences root has been read. The system tree has not been modified or written to, but the flush() call is nevertheless throwing an exception. This occurs when running as a normal user without the ability to write to /Library/Preferences.
See sample code below. Note that I only want to read the system prefs tree. The user tree write flush fails. If the system tree node is not created, the user flush() succeeds.
Steps to Reproduce
Delete any existing Java prefs files:
~/Library/Preferences/com.apple.java.util.prefs.plist
~/Library/Preferences/com.mycompany.prefstest
/Library/Preferences/com.apple.java.util.prefs.plist
/Library/Preferences/com.mycompany.prefstest
Run the following Java code:
package com.mycompany.prefstest;
import java.util.prefs.BackingStoreException;
import java.util.prefs.Preferences;
public class PrefsTest {
      * @param args
     public static void main(String[] args) {
          String strKey1 = "com/mycompany/prefstest/one/two/three/four/key1";
          Preferences systemRoot = Preferences.systemRoot();
          Preferences userRoot = Preferences.userRoot();
          // Get a value for user prefs.
          String value1 = userRoot.get(strKey1, "missing");
          // Fall back to system prefs if it is not defined.
          if (value1.equals("missing"))
               value1 = systemRoot.get(strKey1, "missing");
          System.out.println("key1 --> " + value1);
          // If still not defined, set a user-specific value
          if (value1.equals("missing"))

Expected Results
Should produce the output:

Actual Results
Console output is
key --> missing

Just for fun, try a key without slashes in it (but for example dots if you must use such a long key).
I say that because a quick Google search points out that Apple stores the preferences in a file hierarchy in the user home folder. I can already see how using keys which look like a file path are going to cause nuclear reactors to meltdown...

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?

Core dump on throwing exception

Hi,
I am using an exception class derived from C++ standard exception class (MyException). In this, I am having a member variable of type std::string. I am using this in a DLL that is being used by Java application using JNI.
In my C++ code, I am catching exception following way:
catch(XException& exp)
catch(MyException& exp)
catch(exception& exp)
If I am using std::string as member in MyException class, it results in a coredump whatever exception is thrown (MyException or any other unknown exception supposed to be caught in the standard exception class.). Note that this happens in release build of my dll and never repeatable in debug build.
This problem occurs only in Solaris (tested both in Solaris 7 and Solaris 8). It does not occur in Windows.
Now, if I use char array instead of std::string the problem does not occur!!!! Exceptions are caught properly.
If anyone can throw more light on why usage of std::string causes issues in exception handling in Solaris using CC 5.0 compiler, it shall be of help. I feel problem might be due to not updating the patches related to CC 5.0 exception handling. Also, is it a good practise to use std::string in exception handling classes?

C++ 5.0 is very old and is no longer supported. Patches are still available for it, however. You should get the latest patches from
http://access1.sun.com/sundev
and see if that solves your problem. If not, you should upgrade to a supported compiler release.
The standard string class can perfrom dynamic memory allocation and can throw exceptions. It's not ideal for use in exception handling for those reasons. But for ordinary situations when you are not out of memory it' s probably OK.

Advanced Datagrid GroupingCollection of flat data (XMLLISTCollection) while sorting throws exception

HI,
     Iam using AdvancedDatagrid inorder to group the flat data populated from the backend through BlazeDS. Result data will be in xml format and i have converted it to xmllistcollection and assigned to the grouping collection source. Flat data is grouped by one of the attribute called 'Name' and refreshed after data has been populated.
Data structre used as input is: WIth this structure, iam grouping by the field 'Name'.

Grouping is done as expected. We have additional functionalities like soring / seraching of the result set. Either one is working fine. Other functionality throws excpetion mentioned below.
When any of the advanced datagrid grid column header is clicked for sorting, it throws exception. I have pasted the exception below for reference.

I tried with couple of options but still not able to get rid of the excpetion. I browsed through couple of links also, still not able to find an solution. Can i know whether it is a bug or it can be fixed.
Any help / suggestions on this will be great.
Thanks in Advance,

Print out meaningful exception messages

Hi There,
I have sucessfully imported java classes to forms. Java talks to webservices.
the CLient java that talks to forms throws Exception
public class ANB {
public static String ANB(java.lang.String b) throws Exception{
............code..................
return a;
private static String a = "";
In the forms I have
call ANB
WHEN Ora_java.Java_error THEN
Message ('Unable to call out to Java, ' || Ora_java.Last_error);
WHEN Ora_java.Exception_thrown THEN
Raisedexception := Ora_java.Last_exception;
Message (Exception_.Getmessage_347 (Raisedexception));
Ora_java.Clear_exception;******************************
With the code written above, if an error occurs then error message displayed is as follows:
java.sql.SQLException: ORA-21111:
ORA-06512: at "ABCD.TestTable_BIUR", line 6
ORA-04088: error during execution of trigger 'ABCD.TestTable_BIUR'
ORA-06512: at line 1............
I want the error message displayed, to be meaningful to the user. Say for example,
if an user defined Exception ORA-21111 was raised , i want only the error message associated with the error code to be shown.
Thanks

Yes this seems a good idea. I recommend you do that.
Please next time ask an actual question. I suspect the answer to your unasked question is to look at using methods like getVendorCode or getSQLState of java.sql.SQLException.

Can't throw exception inside try block!

Hi,
I'm having a problem trying to throw an error inside a try block.
To illustrate:
public class TestException {
public TestException() {
try {
int ret = foo();
System.out.println("ret is " + ret);
} catch (Exception ex) {
System.out.println("exception caught");
public int foo() throws Exception {
int ret = 0;
try {
throw new Exception("test exception");
} finally {
return ret;
public static void main(String[] args) {
new TestException();
If I run this the only output is "ret is 0" - I do not catch the thrown exception! What am I doing wrong?
Any and all help will be very gratefully received.
Thanks.

I need to correct myself: I've re-read the spec, and actually the behaviour is conformant with the JLS: JLS says that the return statement completes abruptly, and an abrupt return in a finally block that didn't have a (applicable or any) catch block will result in the original exception being 'forgotten'.
Very unintuitive, but as-spec'ed

Task.cancel() throw exception

Hi,
I'm new to JavaFx and recently try out example on javafx.concurrent.Task:
Example is from a book:
The following is the model class
private static class Model {
        public Worker<String> worker;
        public AtomicBoolean shouldThrow = new AtomicBoolean(false);
        private Model() {
            worker = new Task<String>() {
                @Override
                protected String call() throws Exception {
                    updateTitle("Example Task");
                    updateMessage("Starting...");
                    final int total = 250;
                    updateProgress(0, total);
                    for (int i = 1; i <= total; i++) {
                        try {
                            Thread.sleep(20);
                        } catch (InterruptedException e) {
                            if (isCancelled()) //I modified this part to check for isCancelled()
                                return "Cancelled at " + System.currentTimeMillis();
                        if (shouldThrow.get()) {
                            throw new RuntimeException("Exception thrown at " + System.currentTimeMillis());
                        updateTitle("Example Task (" + i + ")");
                        updateMessage("Processed " + i + " of " + total + " items.");
                        updateProgress(i, total);
                    return "Completed at " + System.currentTimeMillis();
    }On JavaFx, it has 2 Label that are bind to Worker.value and Worker.exception as shown below:
value.textProperty().bind(
                model.worker.valueProperty());
            exception.textProperty().bind(new StringBinding() {
                    super.bind(model.worker.exceptionProperty());
                @Override
                protected String computeValue() {
                    final Throwable exception = model.worker.getException();
                    if (exception == null) return "";
                    return exception.getMessage();
            });Next: There are 3 buttons "Start", "Cancel" and "Exception". Following is the method to hook up events to all three buttons:
private void hookupEvents() {
        view.startButton.setOnAction(new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent actionEvent) {
                new Thread((Runnable) model.worker).start();
        view.cancelButton.setOnAction(new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent actionEvent) {
                model.worker.cancel();
        view.exceptionButton.setOnAction(new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent actionEvent) {
                model.shouldThrow.getAndSet(true);
    }Now, first test is when Task is successfully executed. Value label will be filled with the return value i.e: Completed at ......................
Second is throw exception and the result is as what in the book, the exception label is filled with the exception property. i.e. Exception thrown at ..................
But when I test the Cancel button, it throws and exception instead of return a String value.
The exception label is filled with:
"Task must only be used from the FX Application Thread"
Instead of having Value label filled with: "Cancelled at .................."
Can anybody help me please?
Regards,
Henri

i got the same problem and I'm interested in an answer too.
My Workaround was to have a secon AtomicBoolean-Var
public AtomicBoolean cancel = new AtomicBoolean(false);
if (cancel.get()) {
    return "Cancelled at " + System.currentTimeMillis();
}this code works but it cannot be the answer.

WebAuthenticationBroker.AuthenticateAsync throws exception on the desktop

My code (C# - windows store) uses WebAuthenticationBroker.AuthenticateAsync().
This method used to work on the desktop until last week, but now it throws exception
"The process terminated unexpectedly. (Exception from HRESULT: 0x8007042B)"
The code was not changed and the same code that does not work on the PC, does work on the tablet (Surface).
The same code can be found in https://github.com/facebook-csharp-sdk/facebook-windows8-sample
and also at this sample it throws the same exception.
How can I solve this issue?
Ronit

I know it's been a while since the original question was asked, but I've not seen any solutions published for this issue yet. I
recently faced the same issue. It turned out to be misconfigured permissions on the Internet Explorer's Temporary Internet Files folder. If you have changed that location from default to some custom, please make sure that your account has Full Access permission
to this folder. I had Administrators group having full access, and my account was a part of administrators group. It worked in normal browsing scenarios, but Windows apps run in a sandbox with stripped permissions, i.e. they don't get permissions granted to
Admins. Wininet running in the app process was not able to clean up state before starting authentication.
