> Key: DERBY-470

> Project: Derby
> Type: Bug
> Components: Localization
> Environment: IBM's J2ME/CDC/Foundation Profile and JSR169
> Reporter: Deepa Remesh

> As I did not get any response to my mail, I am opening a JIRA issue for this.
> When I run the test i18n/I18NImportExport.java with JSR169 using IBM's J2ME/CDC/Foundation Profile, I get the following exception:
> "JAVA ERROR: java.lang.NoSuchMethodError: java/sql/ResultSet.getBigDecimal(II)Ljava/math/BigDecimal;"
> In the test, LOCALIZEDDISPLAY is on and the table has a DECIMAL column. This causes the exception. On looking at the code, following is done to format DECIMAL types in LocalizedResource:
> if (type == Types.NUMERIC || type == Types.DECIMAL) {
> return getNumberAsString(rs.getBigDecimal(columnNumber, rsm.getScale(columnNumber)));
> }
> where getNumberAsString method does the following:
> public String getNumberAsString(Object o){
> if (enableLocalized){
> return formatNumber.format(o, new StringBuffer(), new FieldPosition(0)).toString();
> }
> else {
> return o.toString();
> }
> }
> As a solution, I am planning to do the following:
> 1. Check for BigDecimal class in the JVM by doing a Class.forName
> 2. Call getNumberAsString for NUMERIC and DECIMAL types only if BigDecimal class is available. Otherwise, return rs.getString.
> This solution would mean that NUMERIC and DECIMAL types will not be localized in these JVM environments. Please let me know if any comments on this.
> Thanks,
> Deepa
