[opencms-dev] upload a file

[Andrea Frittoli]

hi,

I'm trying to upload a files from a JSP page in the OpenCMS VFS. 
When I'm logged in the workplace as admin, if I lock the "uploads"
directory, everything works fine.
If I publish the project, and logout from the workplace, I get an
exception, it seems guest doesn't have the rights to write in the
"uploads" directory (but I granted read/write access to guests)

I tried also something like

  cms.loginUser("admin",password)
  cms.lockResource(WORKING_PATH);

but I get an "Access Denied" exception!

This is the JSP code:

<form method="post" enctype="multipart/form-data" action="#">
      <b>Select a file and submit!</b>
      <input type="file" name="uploader"/>
      <br/>
      <input type="submit" value="upload!"/>
</form>
<%String WORKING_PATH="/andrea/uploads/";
  com.opencms.file.CmsObject cms =
((com.opencms.flex.cache.CmsFlexRequest)request).getCmsObject();
  com.opencms.file.CmsRequestContext reqContext =
cms.getRequestContext();
  com.opencms.core.CmsRequestHttpServlet req =
(com.opencms.core.CmsRequestHttpServlet)(reqContext.getRequest());
  java.util.Enumeration files = req.getFileNames();
  while(files.hasMoreElements()){
    String this_filename = (String) files.nextElement();
    byte[] filecontent = req.getFile(this_filename);
    cms.createResource(WORKING_PATH, this_filename, "binary", null,
filecontent);
  }%>

what's wrong in this JSP? please help! 
TIA
