Re: [castor-dev] Invalid Characters in XMl Generated

[Dennis Sosnoski]

0x00 is not allowed in XML documents under any circumstances, entity encoded or not - it's a value disallowed by the XML specification. The whole control character range of 0x00-0x1F is disallowed except for the whitespace charactres 0x09, 0x0A, and 0x0D. If you want the details check the specification at http://www.w3.org/TR/REC-xml#charsets

As to why this is being output by Castor, I can't help you on that issue. Does Castor just encode a null String as �? If it does, this is a serious error - it should throw a NullPointerException rather than generate an invalid document.

Thanks for info...But if it is a valid character why does the xml parser
gives me error while parsing. Is there any way i can get the parser to parse
this document.

hi,
I find that the xml generated from a bean object gives me invalid
characters. Marshalling used to work fine till i used it on this bean
object. The only change i see here is that the bean is empty and contains

no

data. The resultset which feeds data in the bean did not retrieve any data
from the database and hence the bean was marshalled without any data in

it.

I am unable to understand why this happens.. I also tried initializing the
bean data elements with a default value, still i am getting the garbage
characters. I am pasting the xml file snippet below.
<?xml version="1.0"?>
<ndt plan-status="&#x0;" plan-iD="0" plan-num="" plan-type-code="">
<deferral-limit-amount>0</deferral-limit-amount>

<emp-elig-under-related-qual-plans>&#x0;</emp-elig-under-related-qual-plans>

<collective-bargaining-units>0</collective-bargaining-units>
<non-union-employees-eligible>&#x0;</non-union-employees-eligible>

If the "garbage characters" you refer to are &#x0;, know this: that is an XML entity reference. It refers to character 0x00 in the XML doc's character set. In unicode (and in ISO-8859-1) that is the null character, which in java would be written as '\0'.

If that isn't what you are referring to as "garbage characters," please clarify.
