BeWixt's bug where it cannot generate XML if the root class only
contain a class parameter?
Hi,
I am using the nightly build of the bewixt library, and got the follow
problem on the output where the xml document is not generated. The
problem happen when I have a root class PersonBean where it only
contains a Book class for its parameter:
import java.io.StringWriter;
import org.apache.commons.betwixt.io.BeanWriter;
Public class WriteExampleApp {
public static void main(String[] args) throws Exception {
PersonBean pb = new PersonBean();
pb.setBook(new Book("Edmond Book", "Edmond"));
System.out.println(pb);
StringWriter outputWriter = new StringWriter();
outputWriter.write("<?xml version='1.0' ?>\n");
BeanWriter beanWriter = new BeanWriter(outputWriter);
beanWriter.enablePrettyPrint();
beanWriter.getBindingConfiguration().setMapIDs(true);
beanWriter.getXMLIntrospector().getConfiguration().setWrapCollectionsInElement(true);
beanWriter.setWriteEmptyElements(false);
beanWriter.write(pb);
System.out.println(outputWriter.toString());
}
}
The output:
PersonBean@f6a746[book=Book@13e8d89[name_of_book=Edmond Book,author=Edmond]]
<?xml version='1.0' ?>
PersonBean.class:
import org.apache.commons.lang.builder.ToStringBuilder;
public class PersonBean implements java.io.Serializable {
private Book book = new Book();
public PersonBean() {
}
public PersonBean(Book book) {
super();
this.book = book;
}
public Book getBook() {
return this.book;
}
public void setBook(Book book) {
this.book = book;
}
public String toString() {
return ToStringBuilder.reflectionToString(this);
}
}
Book.class:
import org.apache.commons.lang.builder.ToStringBuilder;
public class Book implements java.io.Serializable {
String name_of_book;
String author;
public Book() {
}
public Book(String name_of_book, String author) {
super();
this.name_of_book = name_of_book;
this.author = author;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
public String getName_of_book() {
return name_of_book;
}
public void setName_of_book(String name_of_book) {
this.name_of_book = name_of_book;
}
public String toString() {
return ToStringBuilder.reflectionToString(this);
}
}
Thanks,
Edmond

no need to be sorry, just means you waited a little longer for your fix
than you might have otherwise.

sorry it's taken a while: my filters missed the misspelled prefix.
yes, this is a bug (in the ignore empty element code). i've just
committed. if you roll from HEAD or wait till the next nightly, i hope
this your problem will be fixed.
