Subject [jira] [Commented] (CXF-3505) CXF attachment doesn't compatible with SUN's ACTIVATION library
Date Tue, 10 May 2011 05:03:03 GMT

    [ https://issues.apache.org/jira/browse/CXF-3505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13031018#comment-13031018

ext2 commented on CXF-3505:
---------------------------

the problem is somewhat releate the javax.acivation.DataHandler's implement; check the difference
of two activation library:

Geronimo's :
    public DataHandler(DataSource ds) {
        this.ds = ds;
        this.flavor = new ActivationDataFlavor(ds.getContentType(), null);
    } 
	// getContentType() of CXF's LazyDataSource will en-force it to be loaded; then:  attachments(not
last one) will cached, and the last attachment still keep delegate to network stream;

Sun's:
    public DataHandler(DataSource ds) {
	// save a reference to the incoming DS
	dataSource = ds;
	oldFactory = factory; // keep track of the factory
    }
	//doesn't call any method of LazyDataSource, so it cannot enforce the CXF's LazyDataSource
to Load; so the attachments are not cached; Then 2 problem will occurs: 1) cannot release
http-connection 2)if user-application doesn't consume the inputstream, just close it. A temporary
file will be left on disk and keep open;
