WebDAV(1)Introduction of WebDAV

WebDAV(1)Introduction of WebDAV

1. configure in tomcat project to start the server part
org.apache.catalina.servlets.WebdavServlet

The configuration in web.xml:

webdav
org.apache.catalina.servlets.WebdavServlet

debug
0


listings
true


readonly
false



webdav
/*

configuration in WebContent/META-INF/context.xml:



2. Learn the open-source project jackrabbit
http://jackrabbit.apache.org
There are both server side and client side of this open-source project.

I made a very simple example of client side as follow:

org.apache.jackrabbit
jackrabbit-jcr2dav
2.4.1


package com.sillycat.easywebdavclient.temprunner;

import java.io.FileInputStream;
import java.io.IOException;

import org.apache.commons.httpclient.Credentials;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.UsernamePasswordCredentials;
import org.apache.commons.httpclient.auth.AuthScope;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.RequestEntity;
import org.apache.jackrabbit.webdav.DavConstants;
import org.apache.jackrabbit.webdav.DavException;
import org.apache.jackrabbit.webdav.MultiStatus;
import org.apache.jackrabbit.webdav.MultiStatusResponse;
import org.apache.jackrabbit.webdav.client.methods.DavMethod;
import org.apache.jackrabbit.webdav.client.methods.MkColMethod;
import org.apache.jackrabbit.webdav.client.methods.PropFindMethod;
import org.apache.jackrabbit.webdav.client.methods.PutMethod;

public class TestJackrabbit {

public static void main(String[] args) throws IOException, DavException {
HttpClient client = new HttpClient();
//Credentials creds = new UsernamePasswordCredentials("admin", "admin");
//client.getState().setCredentials(AuthScope.ANY, creds);

DavMethod mkCol = new MkColMethod(
"http://localhost:8080/netstore-webdav/shared/testfolder/");
client.executeMethod(mkCol);
System.out.println("mkcol testfolder:" + mkCol.getStatusCode() + " "
+ mkCol.getStatusText());

PutMethod put = new PutMethod(
"http://localhost:8080/netstore-webdav/shared/testfolder/1.txt");
RequestEntity requestEntity = new InputStreamRequestEntity(
new FileInputStream("d://1.txt"));
put.setRequestEntity(requestEntity);
client.executeMethod(put);
System.out.println("put image file:" + put.getStatusCode() + " "
+ put.getStatusText());

DavMethod find = new PropFindMethod(
"http://localhost:8080/netstore-webdav/shared/testfolder/",
DavConstants.PROPFIND_ALL_PROP, DavConstants.DEPTH_1);
client.executeMethod(find);
MultiStatus multiStatus = find.getResponseBodyAsMultiStatus();
MultiStatusResponse[] responses = multiStatus.getResponses();
System.out.println("Folders and files:");
for (int i = 0; i < responses.length; i++) {
System.out.println(responses[i].getHref());
}
}

}

3. Sardine
http://code.google.com/p/sardine/
This is a very simple client API.

I made a very simple client side sample as follow:

com.googlecode.sardine
sardine
314


org.slf4j
slf4j-api
1.6.4


org.slf4j
slf4j-log4j12
1.6.4


log4j
log4j
1.2.16


commons-logging
commons-logging
1.1.1


commons-codec
commons-codec
1.6


org.apache.httpcomponents
httpclient
4.2-beta1

...snip...


sardine-google-svn-repo
true
Sardine maven repo at Google Code
http://sardine.googlecode.com/svn/maven/


package com.sillycat.easywebdavclient.temprunner;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.List;

import com.googlecode.sardine.DavResource;
import com.googlecode.sardine.Sardine;
import com.googlecode.sardine.SardineFactory;

public class TestSardine {

/**
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
//Sardine sardine = SardineFactory.begin("admin", "admin");
Sardine sardine = SardineFactory.begin();

sardine.disableCompression();
sardine.disablePreemptiveAuthentication();

if (sardine.exists("http://localhost:8080/netstore-webdav/shared/")) {
System.out.println("shared folder exists");
}

if(!sardine.exists("http://localhost:8080/netstore-webdav/shared/testfolder/")){
sardine.createDirectory("http://localhost:8080/netstore-webdav/shared/testfolder/");
System.out.println("testfolder not folder exists");
}

InputStream fis = new FileInputStream(new File("d://1.txt"));
sardine.put("http://localhost:8080/netstore-webdav/shared/testfolder/2.txt", fis);

@SuppressWarnings("deprecation")
List resources = sardine.getResources("http://localhost:8080/netstore-webdav/shared/testfolder/");
for (DavResource res : resources)
{
System.out.println(res); // calls the .toString() method.
}
}
}


4. apache module mod_webdav
I heard that there is a module named mod_webdav, but I need to build and configure the server side.
