Re: [VFS][WebDAV] access throws ClassCastException: ArrayList cannot be cast Node
Hello Jörg, is this (or a similiar installation) somewhere available over the internet, I would like to debug what types are returned here. (I am not sure I understand what this has to do with XMLConfiguration) I dont think it is a problem of your code, that casting problem should never happen. Feel free to open a Jira Bug for it. https://issues.apache.org/jira/browse/VFS Gruss Bernd Am Fri, 1 Aug 2014 11:26:09 +0200 schrieb Jörg Wille : > @Gary: I am using 2.1-SNAPSHOT Rev.:1609711 > @Martin: I can understand - to an extent - what you write about the > difference between XMLConfiguration and PropertyConfiguration. > But can you explain why is this topic special to webdav in general or > maybe only in combination with Alfresco? > And most importantly, how can I get WebDav to work?

[vfs] webdav access throws ClassCastException: ArrayList cannot be cast Node
@Gary: I am using 2.1-SNAPSHOT Rev.:1609711 @Martin: I can understand - to an extent - what you write about the difference between XMLConfiguration and PropertyConfiguration. But can you explain why is this topic special to webdav in general or maybe only in combination with Alfresco? And most importantly, how can I get WebDav to work? From reading on the projects's web-site, I was in the believe that WebDav is a supported filesystem. Am I doing something wrong in my code? Are there any examples I can have a look at?
RE: [vfs] webdav access throws ClassCastException: ArrayList cannot be cast Node
org.w3c.dom.Node is at the heart of XML and is used by SAX,DOM and STAX
org.w3c.dom is currently not used by the Following implementations in
commons-configurations:
properties
FileSystems such as VFS or Hadoop FS
DB
unless of course we convert Properties/VFSFileEntitiesHadoop/DB to XML DOM Node
which is not happening
to resolve these 2 distinct implementation paths i suggested a split in
Functionality
one for XML (org.w3c.dom.Node)
and one for Properties/VFS/HDFS/DBEntities
So the solution seems to be a re-architecture...I have something running
locally on my box which scans the file extension and then sets up the correct
digesterRules and then sets up the XMLConfiguration for XML
but then uses PropertiesConfiguration for files which use a
PropertyConfiguration for
Properties, VFS, HadoopFS, DB
you can see clearly see this distinction in the rules initialisation within
ConfigurationFactory.java
protected void initDigesterSectionRules(Digester digester, String matchString,
boolean additional)

Re: [vfs] webdav access throws ClassCastException: ArrayList cannot be cast Node
Is this in 2.0 or using the trunk version? If not trunk, can you check out
trunk and test your scenario?

[vfs] webdav access throws ClassCastException: ArrayList cannot be cast Node
This is the first time I use VFS. But local and http file access works.
But using webdav (with *Alfresco* as server) does not work.
The Problem is similar to this one:
http://mail-archives.apache.org/mod_mbox/commons-user/201109.mbox/%3C004001cc769b$ff3e6770$fdbb3650$@queres.com%3E
*I am doing the following:*
private static final String URL = "webdav://
admin:alfresco@192.168.66.124:8080/alfresco/webdav/firmware/";
DefaultFileSystemManager manager = new DefaultFileSystemManager();
manager.addProvider("file", new DefaultLocalFileProvider());
manager.addProvider("http", new HttpFileProvider());
manager.addProvider("webdav", new WebdavFileProvider());
manager.setCacheStrategy(CacheStrategy.ON_RESOLVE);
manager.setFilesCache(new SoftRefFilesCache());
manager.init();
final FileObject fileObject = manager.resolveFile(URL)
System.out.println("Name:" + fileObject.getName());
System.out.println("Attached:" + fileObject.isAttached());
try {
fileObject.isReadable();
} catch (Exception e) {
System.out.println("Message: " + e.getMessage() + "\nCause: " +
e.getCause()+ "\nStacktrace: " + getStackTrace(e));
}
try {
fileObject.getChildren();
} catch (Exception e) {
System.out.println("Message: " + e.getMessage() + "\nCause: " +
e.getCause()+ "\nStacktrace: " + getStackTrace(e));
}
try {
fileObject.isFolder();
} catch (Exception e) {
System.out.println("Message: " + e.getMessage() + "\nCause: " +
e.getCause()+ "\nStacktrace: " + getStackTrace(e));
}
*Result:*

What am I doing wrong? And what does "Attached:false" means?
