Hi,
what is the actual size of of the String before unmarshalling ?

Sure,
I'm having around 29 Objects that are filled up when I unmarshalled a big
String.
Those Objects are parsed out using a mapping.xml file, like the following:
<class name="com.class.objects.parentClassName">
<map-to xml="InquiryResponse" />
<field name="field1" type="string">
<bind-xml name="Field1" node="element"/>
</field>
<field name="inquiryResponseHeader"
type="com.class.objects.className">
<bind-xml name="InquiryResponseHeader" node="element" />
</field>
........etc.....
</class>
<class name="com.class.objects.className">
<field name="id" type="string">
<bind-xml name="id" node="attribute"/>
</field>
<field name="seq" type="string">
<bind-xml name="seq" node="attribute"/>
</field>
.... etc....
</class>
It takes about 1 - 2 minutes to unmarshall this objects. It may be longer
depending on the String received.
I have been thinking also in the possibility to have less objects, for
example, although is much cleaner in a sense to have objects for each "xml
section" that encapsulates information, will it be better to try to enter
information in less objects?
Also I have the context and unmarshaller set up as the following:
Mapping mapping = new Mapping();
InputSource in = new
InputSource(getClass().getClassLoader().getResource("fileName.xml").getPath());
mapping.loadMapping(in);
//Added to increase performance with similar mappings
context.addMapping(mapping);
//End of XmlContext change
Unmarshaller unmarshaller = context.createUnmarshaller();
unmarshaller.setMapping(mapping);
unmarshaller.setValidation(false);
I read somewhere about a .cdr file that needs to be there but my I basically
don't use generated files.
Any idea? I can bring more information if required.....
I really appreciate any thought or direction.

Hi,
I can only second that statement about the (non-) cost of logging.
Having said that, what kind of degradation are you actually observing ?
Can you share some information with us on this subject ?
Kind Regards

Hi, Richard!
If you look through the documentation for log4j, there is a trivial cost
for supplying these log statements and probably much less if you turn
them off.
The cost of this is pretty minor and I wouldn't worry about it.

Subject: [castor-user] Castor Performance Degradation - Can INFO
messages, .cdr file or lot's of classes be the cause of it?
My first reasonable question, can INFO messages as the following:
INFO: org.exolab.castor.xml.UnmarshalHandler - #endElement: bind-xml
INFO: org.exolab.castor.xml.UnmarshalHandler - #characters:
Degrade the performance? (I see in the logs lot's of this messages -
using
Net Beans 6.9.1) and I was curious. Until it ends this type of messages
it
continues with normal processes. Can logging be the cause of castor
degradation?
2.) I was reading about a .cdr file.. would this help? How can I
generate
one?
3.) I have at least 20 classes, some are nested on others.. is there any
chance this can cause degradation as well? Or maybe that a mapping made
in
the xml file can be changed in order to improve performance?
I really appreciate any assistance that anyone can give me...
