decimal replaces with comma (34.00 is replace 34,00)

[mdelson]

We are testing our application with wildfly 10/ Java8

we have set

-Duser.language=en to the JAVA_OPTS

and in standalone.xml we have set the system-properties as below

<system-properties>

<property name="org.jboss.dashboard.LocaleManager.installedLocaleIds" value="en,es,de,fr,ja,pt"/>

<property name="org.jboss.dashboard.LocaleManager.defaultLocaleId" value="en"/>

</system-properties>

But still we see that in the number format (dot) is replacing with  (comma)

Exception in miscInvoice service::java.lang.NumberFormatException: For input string: "197942,00"

all works fine when we restart the wildfly instance and after 3-4 hrs this issue is seen. Any idea what would be triggering this issue?

[jaikiran]

Which exact version of WildFly? Please post the entire exception stacktrace. Also, how and where are you providing that numeric value?

Why did you set this system properties? They do noting for WildFly at all.

Thanks for the reply. I thought may be setting the system locale should help which actually didn't.

WildFly Version : wildfly-10.0.0.Final

Java Version : jdk1.8.0_72

we have only NumberFormatException seen as posted in initial post. There is no additional exception seen in server log.

we are using below code to change the number format

DecimalFormat amtFormat = new DecimalFormat("0.00");

......

...

double availableCredit = result.getDouble("AVAILABLE_CREDIT");

form.setAvailableCredit(amtFormat.format(availableCredit));

The DecimalFormat constructor used above will use a locale specific DecimalFormatSymbols, specifically, the instance returned via: DecimalFormatSymbols (Java Platform SE 8 )

More details regarding locales and how to set the default locale for the JVM can be found here:

Will follow the link and confirm.Thank you.

Hi Micheal,

We are facing a similar issue, which works for 2-3 hrs after restart and later get the same decimal format error. Was your issue resolved and what was the change done?

[mdelson]

we have resolved by handling the same at the code level

=====================static method===========================

import java.text.DecimalFormat;

import java.text.NumberFormat;

import java.util.Locale;

public class CustomNumberFormat

{

  public static DecimalFormat decFormat = null;

  static

  {

  decFormat = (DecimalFormat) NumberFormat.getNumberInstance(new Locale("en", "UK"));

  }

public static String twoDecimalFormat (double inValue)

  {

  String outValue = null;

  try

  {

  decFormat.applyPattern("#0.00");

  outValue = decFormat.format (inValue);

  } catch (Exception e) {

  }

   return outValue;

  }

public static String oneDecimalFormat (String inValue)

  {

  String outValue = null;

  try

  {

  double parseValue = Double.parseDouble (inValue);

  decFormat.applyPattern("#0.0");

  outValue = decFormat.format (parseValue);

  } catch (Exception e) {

  }

return outValue;

  }

================================================

call the same where ever needed as below

CustomNumberFormat.twoDecimalFormat(Double.parseDouble(resultTableData.get(i).get("MY_AMOUNT").toString()))
