Hi ,
Have got a strange pbm
I have to implement a JList component in my application. I have used DefaultList Model with it.
But when I call ,list.clearSelection() or any other function to empty the list, application throughs Array Index out of bound exception.
I m waiting for Ur sugesstions...
Thanks for the advicers...
Sapna

Inorder to refresh the list contents try following code:
DefaultListModel dlm = new DefaultListModel();
JList jlist = new JList(dlm);
//processing...
//CODE FOR REFRESHING JLIST
//if elements are present in List, remove them.
if (dlm.size() > 0)
dlm.removeAllElements();
//add all elements in model one by one.
for(int i = 0; i < al.size(); i++)
dlm.addElement(al.get(i));
if (dlm.size() > 0)
if(!jlist.isSelectionEmpty()) jlist.clearSelection();
//now if the defaultlistmodel has got any elements then select first
//element
jlist.setSelectedIndex(0);
}Manish.

PDFLPrintDoc function throw exception on Mac in PDF Lib 10

Hi,
Currently I'm doing the work of upgrading a xcode project on Mac from PDF lib from 8.1 to 10.
After change to use PDF lib 10 framework, and build project, I found it throw an exception when calling function PDFLPrintDoc to print PS type, error message saying An internal error occured.
However, on Win platform, it is ok.
I read from release note that since PDF lib 9,
PDFLPrintDoc() honors only default values for tilingMode (kPDNoTiling)
In the previous code, the flattenInfo variable in PDPrintParams is a null porinter, so I manuall add code to set PDFlattenTilingMode to be kPDNoTiling.
But the problem is, now when running ,it still throw exception saying "An internal error occured" , nothing changed.
Has anybody here encountered such problem?
Please give me an answer, thanks~

Since this is PDFL, you have a license from either Adobe or Datalogics. Please contact their support directly.

Custom XSLT Functions Throw Exception

Hi,
I have following requirement-
1. I have defined and configured some custom XSLT functions in Jdev and BPEL, which throw exception in case of an error.
2. Now I want to catch that exception in my BPEL process
3. In My BPEL process I have defined transformation step ( which is using those Custom XSLT functions) in a scope and added a catch branch to that
4. But even XSLT java function throw an exception , it is not being catch by catch branch.
Could you please help me regarding this and tell me any other way to catch an exception in BPEL process thrown by Custom XSLT function within transformation step?
Thanks.

Hi,
Its the problem with the date. In the configuration file i used dateTime for java.util.Date, because of this i cant see "User Defined" option in Jdeveloper component pallete. I checked at XML data types i had seen dateTime for java.util.Date Class, but its not working.
Do anyone created a custom xslt function which has date as parameter or return type?, If so wht they had used as data type for xml and java.

Function module JOB_CLOSE throwing exception

Hello,
We have a batch job which has 2 steps:
1) Step 1 uses job_open, job_submit and job_close and immediately schedules batch job A/P_ACCOUNTS which in turn creates batch input sessions A/P_ACCOUNTS.
2) Step 2 Processes A/P_ACCOUNTS sessions created yesterday or today.
In few cases, job_close is throwing exception job_close_failed. I believe that error is coming due to non availability of work processes. Job A/P_Accounts is defined as a class C batch job. There is a check in the FM job_close which does the following check:
- if the class of a batch job is B or C, it calculates the number of free work processes. If there are no work processes available then JOB_CLOSE throws JOB_CLOSE_FAILED exception.
- If the class is u2018Au2019, it skips this check.
We have an option of changing the class of batch job to A but there are some system critical jobs that are running as class A.
My question is:
In the code, JOB_CLOSE has been called for scheduling the job A/P_ACCOUNTS with parameter start immediately. Can anyone please let me know what will happen if function JOB_CLOSE is not called with start immediately option? Will the batch job A/P_ACCOUNTS wait till the time work processes are available?
Or, can anything else be done to solve the issue?
Regards,
Siddharth

HI,
This is my experience with job_close..
when i was working in zprograms then i was able to scedule it any time i wanted..
but in my standard program when i tried it didn't worked....
so i have to use that option of starting it immediately..
and then it is working fine..
now if i schedule 5 jobs... one after another..
its get queued up...and once the processor is free...its working..
my code of job close

Faxing of SAPScript throwing exception

Dear All,
I am facing problem while sending Sales Order output through FAX. It is throwing exception in OPEN_FORM function module as FAX_NOT_VALID. I debugged and found that actually system is failing FM SX_NUMBER_TO_DEVTYPE which in turn showing that the exception has occured due to Node not found. Is it a configuaration issue? I tried to configure through SPRO but could not find any relevent place. Looking for your valuable suggestion.
Any suggestion!
Thanks and regards,
Atanu

Make sure are you entering the correct fax number in the recepient.
Go to transaction SBWP - > create new message and try to send it as FAX. It you are not able to send fax via Business workplace then it implies that some setting is required form the BASIS.
Otherwise the parameters passed to the OPEN_FORM needs to be investigated.

Count() function throws error in EQL query for metric

Hi
I am trying to use count function in EQL query for Metric Bar to show the number of occurrences of a record.
When the record type doesn't exist i expect the function to return count as 0. Instead the function throws a runtime exception and the whole Metric Bar portlet fails, with error No Results Available. Even though other components in the metric bar have valid results.
2013-02-21 13:03:51,216 WARN [MetricsBarQueryProcessor] The EQL query does not return any results.
2013-02-21 13:03:51,216 ERROR [MetricsBarQueryProcessor] The EQL query does not return any results.
2013-02-21 13:03:51,216 WARN [MetricsBarResultsProcessor] No statement results to process.
The EQL query i am using is
RETURN NUMBER_OCCURS AS SELECT COUNT(EMP_ID) AS NUMBER_OCCURS where EMP_NAME IS NOT NULL group;
I tried using COALESCE but that doesn't help.
Can some one please suggest a workaround to this?

Srikanth,
Two statements are used here because the original question was pertaining to the null set (where there are employees in the nav state but no employees that fit the special analytics criteria in the navigation state). The question/answer has nothing to do with what is in the COUNT parentheses clause as Counting a null set will always give you NULL, not 0, no matter what you put in there.
What we're really doing, in the second part of the query, is writing a query over a set of data that is not the null set (i.e. the current navigation state). This allows the 0 value to come through in the case where the first analytics statement is evaluated over a null set of records. If there were truly no records in the navigation state, this too would return a null set and not zero.
Hope that makes sense, feel free to respond (either on here or offline) if it's unclear.

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.

How does it work : String MethdName (argument) throws Exception {}

HI,
I am very new to Java. I was looking through some code written by some other developer.
the code looks like
String MethdName (argument) throws Exception {
// some code here
What it exactly means? Are we forcing this method to always throw an exception? or only if some exception occurs then it will throw the exception?
Regards,
Lucky

It doesnt throw exceptions always.
What this means is that if you code inside the method does use some API or function that throws exceptions when a particular condition is not met, you method would throw the same exception to it's caller. If you didn't add the throw exception clause in your method, you would have to try/catch the exception that would be thrown in your code.
Or else, your code won't compile.
Summary:
A method that throws an uncaught, checked exception must include a throws clause in its declaration.

You probably have not seen anyone reporting the exact same problem as you. All three crash reports have the same crash signature and as currently ranked 67 it is not the commonest of reasons for a crash.
I hope you enter your email contact information when reporting crashes. I note you see this crash when using videos, others may possibly see this crash in other circumstances.
You have already tried the obvious, attempts at a fix so it is now down to wait and see, maybe developers working on the bug will report something or fix it.
Did you try my suggestion of installing portable ESR ?

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.
Please mark as answer if this resolves your issue.

How to throw exception in run() method of Runnable?

Hi, everyone:
I want to know how to throw exception in run() method of interface Runnable. Since there is no throwable exception declared in run() method of interface Runnable in Java API specification.
Thanks in advance,
George

Thanks, jfbriere.
I must add though that if your run() methodis
executed after a call to Thread.start(), then
it is not a good choice to throw anyRuntimeException
from the run() method.
The reason is that the thrown exception won't be
handled appropriately by a try-catch block.Why do you say that "the thrown exception won't be
handled appropriately by a try-catch block"? Can you
explain it in more detail?
regards,
George
Because the other thread runs concurrently with and independently of the parent thread, there's no way you can write a try/catch that will handle the new thread's exception: try {
myThread.start();
catch (TheExceptionYouWantToThrowFromRun exc) {
handle it
do the next thing This won't work because the parent thread just continues on after myThread.start(). Start() doesn't throw the exception--run() does. And our parent thread here has lost touch with the child thread--it just moves on to "do the next thing."
Now, you can do some exception handling with ThreadGroup and uncaughtException(), but make sure you understand why the above won't work, in case that was what you were planning to do.

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 Java mapping and handle this in BPM

Hi,
I'll use a Java mapping in a BPM transform step. Is it possible to throw an exception inside this Java mapping and handle this in a BPM exception handler?
thanks and regards
Verena

Hi Verena,
In a BPM transformation step, I think you can throw exceptions only for system errors.
Let me explain with an example, one of the ways to handle your scenario:
Lets assume your Java Mapping fails then you can trap that exception in your Java mapping and compose an XML message which indicates that an error has occurred.
say for e.g.
<intermediateStructure>
<SatusDocument>
<StatusCode>ERROR</StatusCode>
<ErrCode>123</ErrCode>
<ErrDesc><!populate the thrown exception details></ErrDesc>
</StatusDocument>
<Payload>
<!contains actual XML message with data>
</Payload>
</intermediateStructure>
if Java mapping is Successful, you can compose the XML message as follows:
<intermediateStructure>
<SatusDocument>
<StatusCode>SUCCESS</StatusCode>
<ErrCode>0</ErrCode>
<ErrDesc></ErrDesc>
</StatusDocument>
<Payload>
<!contains actual XML message with data>
</Payload>
</intermediateStructure>
You can use BPM switch operation to switch to different processing branches say for e.g. "error" branch or "success" branch by examining the value of <StatusCode> tag.
Hope it helps !

** 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.

Hi Mahesh,
I refered those scenarios. But, our requirment is we want to take 'Additional Text' option from SXMB_MONI and map to WS source structure one element.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1"><SAP:Category>XIServer</SAP:Category><SAP:Code area="INTERNAL">PL_TIMEOUT</SAP:Code><SAP:P1/><SAP:P2/><SAP:P3/><SAP:P4/><SAP:AdditionalText>TIME OUT REACHED</SAP:AdditionalText><SAP:ApplicationFaultMessage namespace=""/><SAP:Stack>Timeout condition of pipeline reached
</SAP:Stack><SAP:Retry>N</SAP:Retry></SAP:Error>
Could you kindly help me ?

How to throw Exception in Thread.run() method

I want to throw exception in Thread.run() method. How can I do that ?
If I try to compile the Code given below, it does not allow me to compile :
public class ThreadTest {
     public static void main(String[] args) {
     ThreadTest.DyingThread t = new DyingThread();
     t.start();
     static class DyingThread extends Thread {
     public void run() {
     try {
               //some code that may throw some exception here
          } catch (Exception e) {
          throw e;//Want to throw(pass) exception to caller
}

(a) in JDK 1.4+, wrap your exception in RuntimeException:
catch (Exception e)
throw new RuntimeException(e);
[this exception will be caught by ThreadGroup.uncaughtException() of this thread's parent thread group]
In earlier JDKs, use your own wrapping unchecked exception class.
(b) if you know what you are doing, you can make any Java method throw any exception using Thread.stop(Throwable) regardless of what it declares in its "throws" declaration.
