JAXB problem with DTD file

Question

Hi All,
I just started to learn JAXB and I come to a point in which I need to run xjc on a dtd file and jxs file. The problem is that is gives me an ERROR :
"parsing a schema...
[ERROR] The markup in the document preceding the root element must be well-forme
d.
line 1 of checkbook.dtd
This is my dtd file:
<!ELEMENT checkbook ( transactions, balance ) >
<!ELEMENT transactions ( deposit | check | withdrawal )* >
<!ELEMENT deposit ( date, name, amount )>
<!ATTLIST deposit category ( salary | interest-income | other ) #IMPLIED >
<!ELEMENT check ( date, name, amount, ( pending | void | cleared ), memo? )>
<!ATTLIST check number CDATA #REQUIRED category ( rent | groceries | other ) #IMPLIED >
<!ELEMENT withdrawal ( date, amount ) >
<!ELEMENT balance (#PCDATA) >
<!ELEMENT date (#PCDATA ) >
<!ELEMENT name (#PCDATA) >
<!ELEMENT amount (#PCDATA) >
<!ELEMENT memo (#PCDATA) >
<!ELEMENT pending EMPTY >
<!ELEMENT void EMPTY >
<!ELEMENT cleared EMPTY >
What is the problem with it?
Need your help and THANKS in advance

Try adding dom4j.jar (http://www.dom4j.org/) to your classpath and compiling with the -dtd switch. E.g.:
xjc -dtd foo.dtd
