Commons betwixt 0.8 - reading Map from XML
Hi. I am trying to load a map of String, Object from XML back to java using
betwixt - with no success.
I've exported a Hashtable of String, Object to XML using Betwixt 0.8. The
XML i've got is:
?xml version=1.0 encoding=UTF-8 ?
metadata
map
emptytrue/empty
entry
keygabbaGabbaHey/key
valuemd-id-2/value
/entry
entry
keyEntry1/key
value123/value
/entry
entry
keyhalooppoRoste/key
value-3.76/value
/entry
/map
/metadata
After that, i am trying to load the XML back by the following code:
BeanReader beanReader = new BeanReader();
beanReader.getXMLIntrospector().getConfiguration().setAttributesForPrimitives(false);
beanReader.getBindingConfiguration().setMapIDs(false);
try {
beanReader.registerBeanClass(map, Hashtable.class);
beanReader.registerBeanClass(entry/value,
String.class);
Object tmp;
File srcFile = new File(metadata.xml);
tmp = instance.beanReader.parse(srcFile);
} catch (Exception ex) {
logger.log(Level.SEVERE, Failed to read metadata.,
ex);
return null;
}
I played with beanReader.registerBeanClass - tried to set metadata/map and
metadata/map/entry/value as first parameter, disable registerBeanClass
commands, remove metadata tags from XML, but the only results i've got are
null in tmp variable, or EmptyStackException

Re: [SCXML] Java-scxml interaction
Hello, I need this this info very much:(... I am trying to do something with invoke now. Is it a good way? If yes, can I please have any examples. Anna 2008/8/31 Anna Klisiewicz [EMAIL PROTECTED] Hi I don't know how to make bridging between scxml and java possible. In my program first I run the state machine. In some of the states, I would like to ask user questions (together with the transitions) and come back to the execution of state machine after getting an answer. How to do it? I tried triggering events, but I am not sure if that's the right way. What about listener?.. Thank you, Anna
Re: [SCXML] Java-scxml interaction
Not actual anymore - I think I have done it with invoker. By the way, how to get access to datamodel? So far I was doing it in the same function where I was executing SCXML. now I want use them in conditions in Invoke function. Shall I send them by param or is there more convienient way, like getData() or something Sorry for the spam Anna
