Ian Jones commented on XMLBEANS-175:
------------------------------------
I've been experiencing the same issue, and agree the exponents 1.5 BigDecimal
spits out are not valid in xs:decimal.
However the above workaround does not always work:
java.lang.System.out.println(new java.math.BigDecimal("0.00000001").toString());
java.lang.System.out.println(new java.math.BigDecimal(new
java.math.BigDecimal("1E-8").toPlainString()).toString());
Prints out:
1E-8
1E-8
I agree with Johannes that the long term solution is to use
BigDecimal.toPlainString() when creating an xml document within the xml beans
code (JavaDecimalHolder.compute_text). However, this would make xmlbeans
incompatible with Java 1.4. Perhaps an 'is 1.5' option could be used when
generating code and use toString and toPlainString when appropriate.
I also agree using XmlDecimal is a possible solution, but that rather bloats my
code (3 lines for every 'set' that used to be 1 line). My current work around
is to use a PlainBigDecimal class which extends BigDecimal and overrides
toString to call toPlainString.

> Having an attribute of type xsd:decimal. Validating a document having set the
> attribute to "4.2E1" fails with error message "unexpected char '69'" (char
> '69' is the E). Value "42" works fine.
> Other XML parsers validate "4.2E1" successfully.
> Parsing fails in
> org.apache.xmlbeans.impl.values.JavaDecimalHolder#validateLexical(String,
> ValidationContext).
> BTW: according to my XML documentation, type xsd:decimal is "same as
> java.math.BigDecimal".
> If this info is correct: IMHO it would be better to rely the
> BigDecimal-parsing capability ... ?
