is it a bug??
Summary: is it a bug??
Product: Slide
Version: 2.1
Platform: All
OS/Version: Windows NT/2K
Status: NEW
Severity: Normal
Priority: Other
Component: WebDAV client
AssignedTo: slide-dev@jakarta.apache.org
ReportedBy: tao_jing_rui@hotmail.com
hi,
I read the WebdavSource class and try to write my own getMethod() method. I add
a new line to get some part of a file, not the whole file, by setRequestHeader
("Range","byte = XXX-XXX"). But the new getMehtod does work correctly after I
add this new line. If I delete the new line, the method works ok. So I wonder
is it a bug of client API??
my code is here:
HttpURL hrl = new HttpURL("http://localhost:8080/slide/files/test.text");
hrl.setUserinfo(username,password);
WebdavResource wdr = new WebdavResource(hrl);
try{
HttpClient client = wdr.getSessionInstance(hrl);
GetMethod getMethod = new GetMethod(URIUtil.encodePathQuery
("http://localhost:8080/slide/files/test.text"));
getMethod1.setRequestHeader("Range", "bytes="0-1024");
int status1 = client.executeMethod(getMethod);
if (status1 == 206) {
InputStream in = getMethod1.getResponseBodyAsStream();
int len = (int)(1024);
byte[] filePart = new byte[len];
in.read(filePart);
in.close() ;
}
wdr.close() ;
}
catch(Exception e){
wdr.close() ;
}
The exception is following:
