Giuseppe,
>xIdFactory.createContentIdentifier(aThePackageUrl+"/META-INF/manifest.xml");
I suppose aThePackageUrl starts with "vnd.sun.star.pkg:". Use
"vnd.sun.star.zip:" instead. pkg denotes an OOo document, where
manifest.xml is an implementation detail and not directly accessible via
UCB API. zip gives you access to the raw zip container content.

Hi all,
After I successfully opened a package (e.g. an ODT document) with Java
using UCB low level APIs, I tried to read the content of one of the
contained streams.
With no luck so far. Is there somewhere some example about how to do that?
After I successfully opened it with (sorry for the ugly indentation):
<Java code>
...
XMultiServiceFactory xMSF = ....
...
Object oUCB = xMSF.createInstanceWithArguments(
"com.sun.star.ucb.UniversalContentBroker", keys );
// Obtain required UCB interfaces
XContentIdentifierFactory xIdFactory =
(XContentIdentifierFactory)UnoRuntime.queryInterface(XContentIdentifierFactory.class,
oUCB);
XContentProvider xProvider =
(XContentProvider)UnoRuntime.queryInterface(XContentProvider.class, oUCB);
...
XContentIdentifier xIdPackStream =
xIdFactory.createContentIdentifier(aThePackageUrl+"/META-INF/manifest.xml");
XContent xPackStreamContent = xProvider.queryContent(xIdPackStream);
String contentF = xPackStreamContent.getContentType();
System.out.println("root folder type: " + contentF);
if(
contentF.contentEquals("application/vnd.sun.star.pkg-stream" )) {
System.out.println("Found a META-INF/metafile.xml
element (the root)\n");
//now open the stream content and try to read it
OpenCommandArgument2 aArg = new OpenCommandArgument2();
aArg.Mode = OpenMode.ALL;// FOLDER, DOCUMENTS -> simple
filter
aArg.Priority = 32768;// Ignored by most implementations
// Fill info for the properties wanted.
Property[] aProps = new Property[2];
Property prop1 = new Property();
prop1.Name = "Title";
prop1.Handle = -1;// n/a
aProps[0] = prop1;
Property prop2 = new Property();
prop2.Name = "IsFolder";
prop2.Handle = -1;// n/a
aProps[1] = prop2;
XDynamicResultSet xSet;
aArg.Properties = aProps;
Object oSet = executeCommand(xPackStreamContent,
"open", aArg);
//convert the object from Object to XDynamicResultSet
Type aType = AnyConverter.getType(oSet);
xSet = (XDynamicResultSet) AnyConverter.toObject(new
com.sun.star.uno.Type
(com.sun.star.ucb.XDynamicResultSet.class), oSet);
// now list the xSet elements
XResultSet xResultSet = xSet.getStaticResultSet();
</code>
where executeCommand() is basically the one found here [1],
It seems the wrong approach since xResultSet throws an exception.
Any help is greatly appreciated.
