FTPS using JDK 1.4, Apache Commons, JScape, JSh

I want to write a stand-alone Java program (not web based, it is Java main class), I want to do FTPS (FTP over SSL) to a remote box outside the firewall. Following are my questions:
1. Does JDK 1.4 support it?
2. Does JDK 1.5 support it?
3. Does Apache Commons commons-net-1.4.1.jar support it in JDK 1.4?
If not, I may look into using JScape or JSh.
Any recommendation on how to write FTPS using JDK package 1.4?
I was thinking of using JDK 1.4 as follows, however do not know if it will support FTPS. However, JDK support is rudimentary.
URL url = new URL("ftp://user01:[email protected]/README.txt;type=i");
URLConnection urlc = url.openConnection();
InputStream is = urlc.getInputStream(); // To download
OutputStream os = urlc.getOutputStream(); // To upload
I have used Apache commons for FTP in the past, but it was not FTPS. I do not think that Apache commons supports FTPS. Please let me know, if Apache commons can also support FTPS.
As far as I know, JScape supports FTPS.
Any recommendation, or suggestion will be helpful.

Hi, i'm with the issue. If you take a look at [http://commons.apache.org/net] you'll see that in version 2.0 ftps is supported. But, up to now i couldn't connect to the server, XFB Gateway in my case, it's difficult to find examples and documentation about it.
Did you you figure out how to do it? If so, please post some help.

Connect to FTP site with Apache commons net FTP client through Proxy

Hello,

System.setProperty("socksProxyPort", "1080");
FTPClient ftpClient = new FTPClient();
try {
System.out.println("connecting");
ftpClient.connect(ftpHostName, ftpPort);
System.out.println("connected");
System.out.println("loging in");
boolean successLogin = ftpClient.login(ftpUserName, ftpPassword);

finally {
try {
System.out.println("loging out");
ftpClient.logout();
System.out.println("disconecting");
ftpClient.disconnect();

I am able to do this using a different FTP client library, ftp4j-1.5.1<ftp://ftp4j-1.5.1> using the following code:
import it.sauronsoftware.ftp4j.FTPClient;
import it.sauronsoftware.ftp4j.connectors.SOCKS4Connector;
public class MyTestFtp4J {
public static void main(String[] args) {
String ftpHostName = "ftp.xxx.com";
int ftpPort = 21;
String ftpUserName = "myUserName";
String ftpPassword = "myPassword";
FTPClient ftpClient = new FTPClient();
ftpClient.setConnector(new SOCKS4Connector("10.148.0.131", 1080));
try {
System.out.println("connecting");
ftpClient.connect(ftpHostName, ftpPort);
System.out.println("connected");
System.out.println("loging in");
ftpClient.login(ftpUserName, ftpPassword);
System.out.println("success login");
catch (Exception e) {
e.printStackTrace();
finally {
try {
System.out.println("disconecting");
ftpClient.disconnect(true);
catch (Exception e) {
e.printStackTrace();
So I know the proxy settings are correct.
The java version I used to compile and run my apps is 1.6.0_06 Does anyone can help figure out what is wrong when I use the Apache commons net FTP client?
Thank you

Is the old AirPort Extreme base station (AEBS)
configured so that the option to distribute IP
addresses is DISABLED? If so, configure the new AEBS
to act as a bridge.
Are you suggesting I use a set-up with TWO AEBSs? Set up a bridge (not sure how) and then use the old AEBS to connect to the DSL modem and broadcast to the new Extreme which will then be the router to the other computers on the network?
Do you have any port mapping or default host enabled
on the old AEBS?
I do not understand, not do I see these options in the Base Station utitlity; perhaps they are in the FTP options--but that, I'm sorry to say, is not obvious to my inspection.
Duane, can you give me a few more basic instructions? Thanks

Apache Commons Net - Retrieve File - Extension, Compare , Move - FTP Server

Dear All,
I am using Apache Commons net FTP Library for FTP Operations. I had a few doubts
1) I like to retrieve ftp files only with some extensions like *.txt or *.jpg etc. How can we retrieve files with specifying file extension?
2) I need to compare the FTP Files with the local files before downloading from the FTP Server?
3) I need to move files from the ftp server to local directory. Is there is anyway to move the files rather than first retrieve files from the FTP Server and then deleting the file in the FTP Server using FTP delete()
Thanks,
J.Kathiresan

1) I like to retrieve ftp files only with some
extensions like *.txt or *.jpg etc. How can we
retrieve files with specifying file extension?
List the files and then filter the list to those that you want to process.
2) I need to compare the FTP Files with the local
files before downloading from the FTP Server?Think about this one! To compare two files you nead to read both. If you do this on the client then you will have to copy the file from the server first!
>
3) I need to move files from the ftp server to local
directory. Is there is anyway to move the files
rather than first retrieve files from the FTP Server
and then deleting the file in the FTP Server using
FTP delete()What is wrong with copy then delete?

Problems when using shared instances of struts and apache-commons?

I found this worrisome statement on this page (http://struts.apache.org/1.3.8/userGuide/configuration.html) regarding sharing jar files across multiple applications:
<i>When a class is loaded from a shared class loader, static variables used within that class become global as well. This can cause inter-webapp conflicts when the underlying code assumes that the statics are global only within a particular web applicaiton (which would be true if the class was loaded from the webapp class loader). There are many cases where the framework, and the Commons libraries it relies on, use static variables to maintain information that is presumed to be visible only within a single web application. <b>Sharing these JAR files can cause unwanted interactions, and probably cause incorrect behavior</b>.</i>
For those of you currently using Struts and Apache Commons (and perhaps other open source libraries) have you run into any issues when sharing the jars amongst multiple applications?
I would like to avoid having multiple applications loading their own copies of these libraries, for obvious reasons. However, if there are issues with doing so, I may have to relax that position.

To answer my own questions, while we didn't run into any issues with sharing Struts, it may be a good idea to incorporate the libraries directly into the web app if suspicious behaviour is observed by the application.
Also, the taglib definitions could not be loaded from the referenced jar files - these had to be placed into the WEB-INF directory, which introduces a synchronization problem - you could conceivably have different versions of the tld's and the base libraries.

Annotation processing using JDK 1.6 and Apache Ant

Hello,
I am trying to run my annotation processor using ant.
I already built the processor, the javax.annotation.processor.Processor file is in the correct place with the correct content.
The jar with the processor is in the classpath (i can see it in ant -v), but it does not process my classes. in fact, i get the warning:
warning: Annotation processing without compilation requested but no processors were found.Do i have to specify -processor or -processorpath or can i just leave it to the default classpath scanning?
I think everything is in the correct place, because when i compile with maven instead of ant, specifying the processor, it runs nicely. My pom contains:
               <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>

                    </configuration>
               </plugin>i am using jdk 1.0.6_02 and ant 1.7.0.
Can anyone help me find out what am i doing wrong?

In addition to the class files of the process, to allow your processor to be found as a service, make sure you've also provided the needed META-INF data in the jar file. The general service file format is described in
http://java.sun.com/javase/6/docs/api/java/util/ServiceLoader.html
That said, I'd recommend setting an explicit processor path separate from your general classpath.

Using Apache Commons HTTPClient to create a custom socket for Java mail

Does anyone know how to use Apache Commons HTTPClient to create a custom socket for Java mail. This is necessary for me to use NTLM authentication

JavaMail doesn't use HTTP.
If you want to add support for NTLM authentication to one of the standard protocols,
your best bet is to create a SASL provider, although note that only JavaMail's IMAP
provider uses SASL currently. The other protocols should add SASL support, but that
hasn't been done yet.

Tomcat 4.1 Oracle Blob problem using apache commons DBCP

Hi all,
We are using Tomcat 4.1.12, Java 1.4.x and trying to take advantage of the connection pooling that comes with Tomcat(the apache commons DBCP).
We are connecting to a oracle database.
Works fine for everything EXCEPT Blobs. We have a servlet that serves images from Oracle, that works fine when it doesn't use the connection pooling, but throws an exception when we call the
ERROR: Class:DisplayGraphic Method:processRequest(HttpServletRequest request, Ht
tpServletResponse response)
Exception: org.apache.commons.dbcp.DelegatingResultSet
DataSource ds = (DataSource)ctx.lookup("jdbc/db_connection");
Connection conn = ds.getConnection();
PreparedStatement pstmt = null;
ResultSet rs = null;
pstmt = conn.prepareStatement("SELECT graphic FROM graphics WHERE graphic_id = 1");
rs = pstmt.executeQuery();
if(rs.next())
    oracle.sql.BLOB oBlob = ((OracleResultSet) oRS).getBLOB("GRAPHIC");
    InputStream oIS = oBlob.getBinaryStream();
    ... etc etc...
}Any ideas?
Cheers,
Alex.

solved the problem.. i was using getBLOB instead of
getBlob
doh..Hi Alex,
your problem is very interesting for me because I have a similar problem and your identical configuration...
the instruction
oracle.slq.BLOB aBlob = ((OracleResultSet)super.mRs).getBLOB("BLOBBONE")
causes this:
java.lang.ClassCastException: org.apache.commons.dbcp.DelegatingResultSet
To resolve this, I changed, in server.xml , the factory
<parameter>
                    <name>factory</name>
                    <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
               </parameter>
with:
<parameter>
<name>factory</name>
<value>oracle.jdbc.pool.OracleDataSourceFactory</value>
</parameter>
and magically all works fine...
But the question is... Why doesn't it work with the standard factory???
There is a problem in the CLASSPATH that I don't see?
Any suggestions is welcome!
Thanks in advance!

Hello Peter.
I don't believe you had this working in the past since Apple has always prevented using the .Mac SMTP server for a non-.Mac email account.
I don't believe .Mac provides telephone support.
You can't use Comcast's SMTP server for this email account? Comcast has telephone support but being able to use either Comcast's SMTP server with your Comcast account or the .Mac SMTP server with a .Mac account depends on the ISP used for connecting to the internet when on the road.
If doing so at a hotel, you need to check with the hotel or hotel's ISP for the required SMTP server settings to send mail from an email account outside of the ISP's network.

Apache commons-net

Hi
I was using apache commons-net to FTP some files to an FTP server.
I was able to login to the server. I want to know How can I move out from my root directory. Is it possible using apche coomons-net. The working directory displayed is only /home/myname.
Thanks
Prabhath Nair

If you want to move to a sub-directory within your current root then could it possibly be the changeWorkingDirectory() command?
P.S. You wont be able to move to some directory such as /etc because FTP servers constrain you to stay within a fixed root directory. Often, the home directory of the login name.

Attachements with apache commons fileupload

I'm using:

            factory.setRepository(new File("test"));
            ServletFileUpload upload = new ServletFileUpload(factory);
            upload.setSizeMax(1000000);
            List fileItems = upload.parseRequest(request);
            Iterator i = fileItems.iterator();
            String comment = ((FileItem) i.next()).getString();
            FileItem fi = (FileItem) i.next();
            String fileName = fi.getName();

Problems with Apache Commons Validator

Hello there,
I got a quiet big problem using the a.m. validation framework. When defining a validation rule for a property like this:
<formset>
<form name="testForm">
<field property="firstName" depends="isEmail">
<arg0 key="testForm.firstname"/>
</field>
</form>
</formset>
and instanciating my validator as follows:
Validator validator = new Validator(resources, "testForm");
validator.setParameter(Validator.BEAN_PARAM, name);
everything works fine! I get a correct ValidatorResult object with a correct validation value.
But as soons as I define a second Validation on the same property like this:
<formset>
<form name="testForm">
<field property="firstName" depends="isEmail,isBlankOrNull">
<arg0 key="testForm.firstname"/>
</field>
</form>
</formset>
Nothing works anymore. When iterating over the ValidatorResults object I only get one ValidatorResult object for "isEmail" with a wrong validation value. There should be two working ValidatorResult objects for "isEmail" and "isBlankOrNull"?!?!
Are two validation method in the depends-Attribute not allowed (although it is defined in the standard)?
You can assume, that the used validator class is conform to the given org.apache.commons.TestValidator!
For any help, thx in advance!

The coverageType is only required if the lastName for the same indexed bean is not null, and also if the non-indexed field insureDependents is true.
You can have an arbitrary number of fields by using the [n] syntax, the only restriction is that they must all be AND or OR, you can't mix. "

Commons-fileupload.jar is already in the web-inf/lib.
Is there another solution?Add the jar to the server's shared/lib or common/lib. Did you really need to ask this on an old thread?

Apache commons fileUpload parseRequest finds no form fields-portalComponent

Hello All,
What am I trying?
Developing a portal component (no JSP, no HTMLB).
Have used Apache commons fileUpload libraries.
What is the problem?
parseRequest method works fine when I right click and preview from PCD.
parseRequest method returns 0 html form elements when the portal component is tested under the TLN (via role -> workset -> iview)
What else did I try?
1.
I looked in to Apache documentation - there are two different APIs for two different scenarios, Servlets and Portlets.
My understanding is that I can not use portlets scenario in SAP Portal.
Servlets scenario was what worked while doing a preview from PCD.
2. I have looked into other solutions like using web dynpro and HTMLB to do file upload - not really a fan of either for various reasons.
Can any one help?
I am trying to understand why the HTTPServletRequest when parsed returns 0 form elements in the SAP Portal scenario.
Thanks!

Hello Ankur,
You said:
The reason for this is, unlike the request parameters, the multipart formdata is 'read-once-only' (because once
the data is read off the ServletInputStream, it is gone! It cannot be read again). When you call a full portal request it goes through lot of gets before reaching your component.
The above concept is not fully clear to me. I got a hint to something like this happening from this link that explains the need for portlets API scenario compared to a servlets scenario - Link: http://commons.apache.org/fileupload/using.html
(Search for Servlets and Portlets within that link)
I initially thought something like what you had replied would have happened. However, when I do a getContentLength on HTTPServletRequest in the SAP Portal mode (role -> workset -> iview), the size still includes that of the uploaded document. So like you said "it is gone! It cannot be read again" may not be accurate.
My question still remains open.

Apache commons FileUpload: Pass stream as attribute

I'm trying to implement a Filter that will change all the HTTP parameters to attributs, so that I can handle them in a consistent way throughout my servlets. The apache commons fileupload part is giving me problems. I'm changing the parameters to attributes like this
if(URLENCODED.equalsIgnoreCase(contentType) || contentType == null) // Used with normal form data
Enumeration<String> params = request.getParameterNames();
while(params.hasMoreElements())
    String name = params.nextElement();
    String value = request.getParameter(name);
    request.setAttribute(name, value);
else if(contentType.toLowerCase().startsWith(MULTIPART))     // Used when file is uploaded with POST
// Create file upload handler
ServletFileUpload upload = new ServletFileUpload();
FileItemIterator iter;
iter = upload.getItemIterator((HttpServletRequest) request);
while(iter.hasNext())
    FileItemStream item = (FileItemStream)iter.next();
    InputStream itemStream = item.openStream();
    if(item.isFormField())          // form item
      BufferedReader rd = new BufferedReader(new InputStreamReader(itemStream));
      String line;
      while((line = rd.readLine()) != null)
        streamParamsToAttributes(line)
else          // file
    request.setAttribute("filestream", itemStream);
}In my servlet I use the file stream with following code
InputStream itemStream = (InputStream)(request.getAttribute("filestream"));
useStream(itemStream)Here the useStream() method will throw a FileItemStream.ItemSkippedException since I'm trying to read data from the stream after the iter.next() was called.
So my question is, how to handle this kind of situation? The file can be quite big, so reading it to memory is not wise. And as I read, copying the stream is not a straight-forward task.
I noticed that O'Reilly has also a library for handling file uploads, is it any better in this case?
Thanks.

I looked at the O'Reilly lib and it seems to always save the file to disk. So no streaming possibility.
One solution I can think of would be to 'manually' read the data from the request. I can get the data with request.getReader() call. The file data can be found by the boundary. Now I'm wondering whether this will solve anything. Can anyone see some caveats in this approach?
