[commons-vfs] accessing exploded WAR content at runtime
What'd be a good way to get access to a deployed WAR's content using VFS?
Right now, I'm doing:
servletContext.getRealPath("") + File.separator + "WEB-INF" + File.separator
+ "classes" + File.separator + path;
And this quite inconvenient to rely on servletContext since I don't have
access to it in lower layers, not speaking about the test, which in
isolation don't even run in a ServletContext.
I don't see any other way than using the local file system. But if I do so,
I'll get an absolute path, not a relative to the deployment folder one.
Any idea?

math KMeansPlusPlusClusterer Failing unittest
Hi all,
I have a problem with KMeansPlusPlusClusterer in the trunk. See below for the
unittest. Am I doing something wrong here or is there a bug?
Kind Regards,
Erik
@Test
public void testPerformClusterAnalysis2() {
KMeansPlusPlusClusterer transformer =
new KMeansPlusPlusClusterer(new
Random(1746432956321l));
EuclideanIntegerPoint[] points = new EuclideanIntegerPoint[] {
new EuclideanIntegerPoint(new int[] { 1959,325100 }),
new EuclideanIntegerPoint(new int[] { 1960,373200 }),
};
List> clusters =
transformer.cluster(Arrays.asList(points), 1, 1);
assertEquals(1, clusters.size());
}
[SCXML] Retrieving a (wrapped) NodeSet for an XPath / user defined XPath functions
Dear Rahul, dear all, the result value of an XPath-selection is limited to an XPathConstants.NODE as of XPathEvaluator#evalLocation(Context, String). Having a root element is reasonable for assignments etc. but I'd need to select a NodeSet based on the XPath predicates first (and then wrap it evt. into a result element). My use case resembles the form interpretation algorithm (FIA) of VXML: the of a state is updated continually by the payload of arriving events (inputs). There is an UI (form) which reflects the current datamodel and on each change the remaining "empty" items should be selected and presented for completion: ... Although the XPathEvaluator accpets XPathFunctions as constructor arguments, there are no public accessors to the namespace and variable contexts. Could you please provide an exmaple how to accomplish access to a data NodeSet using an XPathFunction or an other way ? Many thanks !

Re: FileCleanerCleanup question
Hi, is anyone on this list familiar with commons-io / commons-fileupload?
If not, is there somewhere else I should be asking questions?
I still have the issue indicated below, and I have an additional question.
When you parse the request... =>
final List items = (List) upload.parseRequest(request);
commons-fileupload also generates files for form field items (e.g. text box
values). This is an undesired side effect. I want it to generate a file
for the actual file that is uploaded, but not the form fields. Is there a
way to control that?
Thanks in advance,
Davis

I'd recommend using a custom action that captures these specific semantics aiding behavior akin to the FIA, rather than having it happen as a side-effect of a function invocation in an assignment expression. IOW, if you have an action to the effect of the following that has the behavior above: it (a) offers you access to the namespace and variable contexts, and (b) models this separately from since it is indeed a composite operation. -Rahul > Many thanks ! > Jaro > > > > -- > Jaroslav Pullmann > Web Compliance Center - Fraunhofer FIT > Schloss Birlinghoven, D-53757 Sankt Augustin, Germany > Phone: +49-2241-142623 Fax: +49-2241-142065 > - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
Re: monitor file update help
Thanks for the reply :)
I had a look the sites before I post the question.
So far I have this code, but when there's an event for the folder it doesn't
trigger the monitor.
I would like to monitor a folder for any event, such as file creation, delete,
or update.
Any idea what did I do wrong?
[CODE]
public void watchFile()
{
FileSystemManager fsManager;
try
{
fsManager = VFS.getManager();
FileObject sourceFile =
fsManager.resolveFile("ftp://username:passw...@host/myfolder"; ,authenticate());
FileSystem fs = sourceFile.getFileSystem();
DefaultFileMonitor monitor = new DefaultFileMonitor(new
FileListener(){
@Override
public void fileChanged(FileChangeEvent event) throws Exception
{
System.out.println("File Changed" +
event.getFile().getName().getBaseName());
}
@Override
public void fileCreated(FileChangeEvent event) throws Exception
{
System.out.println("File Changed" +
event.getFile().getName().getBaseName());
}
@Override
public void fileDeleted(FileChangeEvent event) throws Exception
{
System.out.println("File Changed" +
event.getFile().getName().getBaseName());
}
});
monitor.addFile(sourceFile);
monitor.start();
}
catch (FileSystemException e)
{
e.printStackTrace();
}
catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
[/CODE]

Re: FileCleanerCleanup question
Hi
You can get both form fields as well as non form fields ( file fields) by
commons file upload and store where you want. I am giving a complete code
for file upload. Hope it will be helpful for you.
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import java.sql.*;
import java.util.*;
import org.apache.commons.fileupload.*;
import org.apache.commons.fileupload.servlet.*;
import org.apache.commons.fileupload.disk.*;
public class MyUpload extends HttpServlet
{
public void doPost(HttpServletRequest request,HttpServletResponse
response)
throws IOException,ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
if(ServletFileUpload.isMultipartContent(request))
{
FileItemFactory factory=new DiskFileItemFactory();
ServletFileUpload upload=new ServletFileUpload(factory);
List fileItem=upload.parseRequest(request);
Iterator itr= fileItem.iterator();
while(itr.hasNext())
{
FileItem fi=(FileItem)itr.next();
if(fi.isFormField())
{
out.print(fi.getFieldName() + fi.getString());
}
else
{
String filename=fi.getName();
InputStream is=fi.getInputStream();
size=is.available();
conttype=fi.getContentType();
// thus you can get file as a InputStream. Now, You can save it in database
or in a dir as you wish.
}
}
}
}
Thanks!

Whether a file is created depends on whether the size is over the
(customisable) threshold. Below the threshold, the item's content will
be kept in memory; above the threshold, it will be written to disk. If
that's not flexible enough for your needs, you can provide your own
FileItem class and your own factory to instantiate it.
