[opencms-dev] How to read a file size

[Cyrill Brunschwiler]

Hi Oli

have a look at the jsp below. it gets all files from the current folder
and builds a little download list. If you would have an idea how it
could look like, go for: http://mobilestreaming.csnc.ch/

// get cms related stuff
CmsJspActionElement cms = new CmsJspActionElement(pageContext, request, 
response);
CmsObject obj = cms.getCmsObject();

// create formatter for dates
DateFormat df = new SimpleDateFormat("dd. MMMM yyyy", Locale.GERMAN);
DateFormat cwf = new SimpleDateFormat("ww", Locale.GERMAN);

// get img link
String img = cms.link("../resources/floppy.gif");

// get all files from current folder
ArrayList list = cms.getNavigation().getNavigationForFolder();
Iterator i = list.iterator();

<table width="100%" border="0" cellspacing="1" cellpading="0" class="border">
   <tr>
      <td class="title">Date</td>
      <td class="title">Week</td>
      <td class="title">Desc</td>
      <td class="title">Version</td>
      <td class="title">Download</td>
      <td class="title" align="right">Size</td>
   </tr>

   while (i.hasNext()) {
      try {
        // get first file from vector
	CmsJspNavElement ne = (CmsJspNavElement)i.next();
        CmsFile file = obj.readFile(ne.getResourceName());
        
        // get the last modified date, calendar week and title
	String lastModified = df.format(new Date(file.getDateLastModified()));
	String lastModifiedCW = cwf.format(new Date(file.getDateLastModified()));
	String title = ne.getTitle();
	
        // get the version stored in a property
        String version = ne.getProperty("version");
        if (version == null) version = "none";
   
	String link = cms.link(ne.getResourceName());
	String size = file.getContents().length / 1024 + "kb";
        
        // get the files extension eg. pdf | doc | xls
        String ext = file.getExtension().substring(1).toUpperCase();
                
        out.println("<tr>");
        out.println("<td>" + lastModified + "</td>");
        out.println("<td>" + lastModifiedCW + "</td>");
        out.println("<td>" + title + "</td>");
        out.println("<td>" + version + "</td>");
        out.println("<td><a href=\"" + link + "\"> " + ext + "</a></td>");
        out.println("<td>" + size + "</td>");
        out.println("</tr>");
      }
      catch (Exception e) {
         // don't worry
      }
   }
}
