Writing Composite and Component Properties
Hi, I am working on https://issues.apache.org/jira/browse/TUSCANY-1482 and its mostly done - just the only thing related writing the property values. The Property class has this value as a xml Document already and it would be good if we could simply write that out. Right now I don't see a way to do this from the XMLStreamWriter interface. I am trying to avoid having to parse this document value which is already an XML doc and then write it again as XML which seems a bit absurd. Would it be good to directly make use of the output stream that underlies the XMLStreamWriter ? If so how would the CompositeProcessor's write method avail this ? Are there other alternatives that people can help me with ? Thanks - Venkat
Re: Writing Composite and Component Properties
Hi, There are a few ways you can handle this: 1) Use the code in the databinding module: Node2XMLStreamReader and then XMLStreamSerializer 2) Use a BSD-licensed StAXUtils at https://stax-utils.dev.java.net/nonav/javadoc/utils/index.html. // create a DOMSource Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(...); Source domSource = new DOMSource(doc); // create a StAXResult XMLStreamWriter writer = XMLOutputFactory.newInstance().createXMLStreamWriter(System.out); Result staxResult = new StAXResult(writer); // run the transform TransformerFactory.newInstance().newTransformer().transform(domSource, staxResult); Thanks, Raymond - Original Message - From: Venkata Krishnan [EMAIL PROTECTED] To: tuscany-dev@ws.apache.org Sent: Thursday, August 30, 2007 6:28 AM Subject: Writing Composite and Component Properties Hi, I am working on https://issues.apache.org/jira/browse/TUSCANY-1482 and its mostly done - just the only thing related writing the property values.

Re: Writing Composite and Component Properties
Hi Raymond, Thanks for responding. As far as I saw the stax-utils have only snapshots published. If this is indeed true then it seems like option 1 is better. But with option 1, is it good to bring in the databinding as a dependency into assembly-xml. To me assembly-xml seems to be at must lower layer to databinding. Please let me know your opinions about this.

Re: Writing Composite and Component Properties
Hi, I meant to re-use some of the code in databinding module instead of adding it as dependency to assembly-xml. BTW, writing a converter from DOM to XMLStreamWriter is probably not too complex.
