Code for Uploading a file over https

This will do what you need:

http://jakarta.apache.org/commons/httpclient/apidocs/org/apache/commons/httpclient/methods/multipart/package-frame.html

>>CEHJ

Yes, using the classes of this package, I was able to post a file over an http server, but my problem now is that it doesn't work directly over https (which is normal); some capabilities need to be added, and I am unable to find them..any help??

Did you try the code using example at

http://jakarta.apache.org/commons/httpclient/apidocs/org/apache/commons/httpclient/methods/multipart/MultipartRequestEntity.html

with an https url?

>>CEHJ

Yes, it gives the following error:

An IOException occurred attempting to POST the file: test.txt

with regular http, the file uploads normally

if thats a test cert then try a custom factory along the lines of:

http://svn.apache.org/viewvc/jakarta/commons/proper/httpclient/trunk/src/contrib/org/apache/commons/httpclient/contrib/ssl/EasySSLProtocolSocketFactory.java?view=markup

>  I have currently a java closed source code that can be used to upload a file over HTTP

depending on the interface it provides you can most likely use it for https.

This TrustManager has to be at the server servelt...right?

>>This TrustManager has to be at the server servelt...right?

It should be at the box from which you're trying to upload

By the way...This is the method in which I am uploading the file:

  private int simplePost(File aFile) throws IOException
  {
    BufferedInputStream bufStream = null;
    int statusCode1               = -1;
    try
    {
      HttpClient client = new HttpClient();

      PostMethod postMethod;
      if (bKeepFilenames == false)
      {
        postMethod = new PostMethod(strUrl);
      }
      else
      {
        postMethod = new PostMethod(fullPostUrl);
      }

      if (authUrl != null)
      {
        logger.info("(authPost) Authentication to url" + authUrl);
        PostMethod authPost = new PostMethod(authUrl);
        StringBuffer strBuf = new StringBuffer(100);
        strBuf.append(contentType).append("; charset=").append(charSet);

        // set the content type and try to automatically follow redirects
        authPost.setRequestHeader("Content-type", strBuf.toString());
        authPost.setFollowRedirects(true);
        int authStatusCode = client.executeMethod(authPost);

        //put the response body in the variable so clients can retrieve it later on
        responseBody = postMethod.getResponseBodyAsString();
        if (verbose)
        {
          StatusLine statLine = authPost.getStatusLine();
          logger.info("(authPost) Status Line: " + statLine);
        }

        if ((authStatusCode < 200) || (authStatusCode > 399))
        {
          logger.info("(authPost) Authentication failed");
          return authStatusCode;
        }
      }

      client.setConnectionTimeout(8000);

      // Send any file as the body of the POST request
      if (verbose)
      {
        logger.info("(simplePost) File length: " + aFile.length());
      }

      bufStream = new BufferedInputStream(new FileInputStream(aFile));

      postMethod.setRequestBody(bufStream);
      postMethod.setRequestContentLength((int)aFile.length());

      StringBuffer strBuf = new StringBuffer(100);
      strBuf.append(contentType).append("; charset=").append(charSet);

      // set the content type and try to automatically follow redirects
      postMethod.setRequestHeader("Content-type", strBuf.toString());

      // add any custom headers
      addCustomRequestHeaders(postMethod);

      postMethod.setFollowRedirects(true);
      statusCode1 = client.executeMethod(postMethod);
      postMethod.releaseConnection();

      StatusLine statLine = postMethod.getStatusLine();
      if (verbose)
      {
        logger.info("(simplePost) Status Line: " + statLine);
      }

      logger.info(buildSummaryLine(statLine, aFile));
    }
    catch (IOException ioe)
    {
      if (bufStream != null)
      {
        bufStream.close();
      }

      throw ioe;
    }

    bufStream.close();
    return statusCode1;
  }

It turned out that the problem is that the cacerts file in which the certificate is added is inside the weblogic folders (since I am using WebLogic for my servlet); when I copied that file to the jdk cacerts folder of the one I am running the client application in, it worked...thanks for you help guys!
