Hi Guoguo,
XStream works well under T5, problem now is, it does not handle UTF-8, any
tips on this too? Thanks.

Indeed Castor is more portable than XStream. But XStream is stronger and
more simpler.
So you have to bear it's slightly bigger size.
But I find all the dependency jars of XStream are about 3m not 5m. And
cglib-nodep-2.1_3.jar,dom4j-1.6.1.jar,jdom-1.0.jar may be also used in other
place.

The castor jar was a little over 1 Meg at last track. (There are different
Castor jars - that is for the XML only jar).
A mapping file is not required. There is a default behavior without any
mapping. I always use a mapping file because I like having control over my
XML.

Hi Jonathan,
I tried XStream as suggested by 蝈蝈龙， it works, but library size is big
around 5mb added, how big is the Castor? one nice thing about XSream is, I
don't have to write any xml mapping, same with Castore? Thanks.

Try Castor at www.castor.org
It's a Java <-> XML tool that favors the Java side. It's easy by default,
but can be very flexible. I use this the most.
If you want to favor the XML side, then XMLBeans at Apache would be better.

Hi 蝈蝈龙,
I tried XStream's toXML, it works, but not yet try writing to a file. one
thing I notice is, the size of lib, the war file's size was increased from
1.9mb to 7mb, looks like XStream is larger than Tapestry's lib, right?

Re: T5: POJO to xml lib

Hi Angelo, you can use it like this:
public class MyClass {
public MyClass(Whatever what ever) { }
public MyClass() {}
public String toXML() {
ByteArrayOutputStream stream = new ByteArrayOutputStream() ;
try {
XMLEncoder encoder = new XMLEncoder(new BufferedOutputStream(stream));
encoder.writeObject(this);
encoder.close();
} catch (Exception e) {
logger.error(e);
}
return stream.toString();
}
}
you can change the ByteArrayOutputStream implementation for a
FileOutPutStream, if you're using a custom constructor in your
implementation you should write a default constructor for it.
public class MyDecoder {
public MyClass decode(String myClassToXmlString) {
XMLDecoder d = new XMLDecoder(new BufferedInputStream(new
ByteArrayInputStream myClassToXmlString.getBytes())));
Object result = d.readObject();
d.close();
return (MyClass) result ;
}
}

Hi Fidel,
I have some problem with XMLEncoder:
http://www.nabble.com/T5%3A-Can-XMLEncoder-be-used-with-T5-app--tf4362923s302.html
how to use this xmlencode to avoid those exceptions? Thanks,

Hi,
you can use XMLEncoder/Decoder from java Api.
make sure you don't do this in a page "delegate" this functionality to your
the infrastructure layer.
