ITMS and Jakarta Commons-HttpClient crazy frequent in log

I'm seeing blocks like this several times an hour in my web log for one of my sites that hosts a few podcasts. In fact, Apple IPs makes of the bulk of clients (7-8 of the top 10) that access my site. Why?

Trying a comprehensive jakarta-commons PKGBUILD....

Hey there!
I would like to build a PKGBUILD for a nice java banking program. On the way to a Arch-conform PKGBUILD I stumbled over the Java Package Guidelines and investigated the libs which are shipped with the program a bit further.
There I found that some jars from the jakarta commons package were used but not yet packaged in AUR or the official repos. So first I wanted to build them separately, but then I found that it would make more sense to have one comprehensive package of (currently) 30MB instead of 33 single packages.
What do you think about the idea? I am willing to support this meta package as well as the single ones if I just knew how the implementation would be more sensible.
Since it would be a huge amount of work to pack every packag on its own, I wrote a PKGBUILD for all packages that are in Jakarta Commons.
I hope, if it is generally desired to have any package in a single file, that I at least learnt a bit from writing this PKGBUILD

Since there are sometimes when copy&pasting PKGBUILDS (especially the ""s, IIRC), here a link to a pastebin
My questions are: Are the jars to be put in /usr/share/java/jakarta-commons/$package/*.jar or plainly under jakarta-commons?
Is it ok to delete all the docs, licenses + readmes?
Sorry but it's very late now so I'll stop here and wait for your suggestions and tips, which will come hopefully..
Greetings and good night,

Your absolutely right saying that never all commons packages would be used by just one program.
I read the Java Packaging Guidelines again and it says that only commoly used and major libs should be sourced out to single packages. So the question is: Do any other packages in AUR or the official repos use some of the jakarta-commons projects so it would eventually pay to make single packages for them, or isn't it worth the hussle?
I for my part now will leave the libs that are bundled with the package I wanted to upload at first in the package and use them.
Thanks for your reply

Jakarta Commons HTTP Client problem

Hi,
This one's for anyone with knowledge of the Jakarta Commons HTTPClient 2.0 Beta 2.
I'm trying to make an HTTP GET request with all the Cookies on one header line.
For some reason the request is built with each cookie on a separate line.
I've looked at the source for HttpMethodBase where I saw that this depends on whether it is in strictMode. So, I set it to strictMode first.
Doesn't seem to make any difference though.
Here's my code. Can someone tell me where I've gone wrong.
HttpClient client = new HttpClient();
HttpState state = client.getState();
state.setCookiePolicy(CookiePolicy.COMPATIBILITY);
state.addCookie(new Cookie("www.foo.com","foo","1","/",null,true));
state.addCookie(new Cookie("www.foo.com","baa","2","/",null,true));
GetMethod method = new GetMethod(url);
method.setStrictMode(true);
int statusCode = client.executeMethod(method);
// ...Hope someone can help.
Thanks.

after reading through the source it appears that HttpClient.strictMode overrides whatever the setting is in HttpMethod.strictMode.
see HttpClient.executeMethod(HostConfiguration hostConfiguration,
HttpMethod method)
in this method is ....
method.setStrictMode(strictMode);
so try this in your code instead of method.setStrictMode(true).
client.setStrictMode( true );

Difference between common-httpclient 3.0 and httpclient 4.0

Hi,
I am using SSL communicaiton between client and server machine.The JDK version is 1.6.0_19.I am using HttpClient 4.0 now.I used common-Httpclient 3.0 earlier. The client and the server both are having the certificate.Here we are doing mutual authentication sending the certificate to each other.
If I use the command -Djavax.net.debug=all command I am able to see the detail client and server communicaiton.I wanted to know, what are the destination server it is reaching and that's why I have used wireShark.I have seen a difference here.If I use common-httpclient 3.0 component then it is reaching the verisign site to import the CRL.But if I use httpclient 4.0 then it is not reaching the verisign site.It might be reaching the verisign site for the CRL check.
I know internally it is using the JSSE component.
Here are my questions :
I like to know why this difference is happening?
Is the httpclient initiate CRL checking?
Howcan I initiate the OCSP instead of CRL check using the httpclient and the JSSE?
how could I check the detail log?
I like to know based on what condition the application is reaching the verisign site(means CRL checking).
Please help me out.

Sync, Backup, iTMS, and Safari are all acting crazy... gah!

So many things aren't working and I have a sneaking suspicion that it's related to Keychain. In a nutshell:
Backup: bottom of main window in Backup says I'm in Trial Mode, limited to 100 megs, hasn't successfully completed a backup since November 4th, the error message says
"Transaction failed for unknown reason (100), Unable to complete backup at this time."
Unable to restore, says "Restore cancelled, Unknown destination."
iTunes: I can browse the iTMS and my already-subscribed-to podcasts update, but I am unable to purchase new songs or subscribe to new podcasts. I get an error message that says: "We could not complete your iTines Store request. An Unknown error has occured (-9813) There was an error in the iTunes Store. Please try again later." I can not sign in to the iTMS.
Sync: Locks up System Preferences and I have to force-quit.
Safari: I get errors when I go to Apple's website and my personalized Google page pertaining to the signer of the certificates is unknown.
.Mac Preference Pane: System Preferences locks up when I click on "Sync" tab, I have to force-quit, when I click on "iDisk" tab, I get this message: "There's a problem connecting to the iDisc server at this time. Please try again later. You may continue to work offline on your local iDisc."
Here's what I've tried to fix these problems:
I've tried to repair my Keychain - I got a message that said it was fine. I dragged my Keychain onto my desktop and restarted, no change. I've verified my .Mac password, I've rebuilt my permissions, I've followed the links sent to me by Apple Tech Support (none of which were pertinent), I've gone through all my logs looking for error messages and found nothing more than that (-9813) error, I've sent 10 emails to Apple asking for help and received nothing more than links to unhelpful articles and recommendations to try things I've already tried (and told them I'd already tried, by the way.)
The iTMS gift card my wife gave me is useless. Backup and Sync are inoperable. I'm really frustrated.
Does anyone out there have any idea what I can try next?
iBook G4 640 MB DDR SDRAM

So here's another thing I tried to do - I re-installed the Security Update COMBO. Didn't help.
I also forgot to mention that I have two accounts on my iBook - one for home and one for work. I'm not sure how Keychain interacts with multiple accounts.

Uploading a file to server using servlet (Without using Jakarta Commons)

Hi,
I was trying to upload a file to server using servlet, but i need to do that without the help of anyother API packages like Jakarta Commons Upload. If any class for retrieval is necessary, how can i write my own code to upload from client machine?.
From
Velu

<p>Why put such a restriction on the solution? Whats wrong about using that library?
The uploading bit is easy - you put a <input type="file"> component on the form, and set it to be method="post" and enctype="multipart/form-data"
Reading the input stream at the other end - thats harder - which is why they wrote a library for it. </p>
why i gave the restriction is that, i have a question that <code>'can't we implement the same upload'</code>
I was with the view that the same can be implemented by our own code right?

Re: How do you create and use "common" type classes?

Hi,
You have 2 potential solutions in your case :
1- Sub-class TextNullable class of Framework and add your methods in the
sub-class.
This is the way Domain class work. Only Nullable classes are sub-classable.
This is usefull for Data Dictionary.
The code will be located in any partition that uses or references the supplier
plan.
2- Put your add on code on a specific class and instanciate it in your user
classes (client or server).
You could also use interface for a better conception if needed. The code will
also be in any partition that uses or references the supplier plan where your
add on class is located.
If you don't want that code to be on each partition, you could use libraries :
configure as library the utility plan where is your add-on class.
You can find an example of the second case (using a QuickSort class,
GenericArray add-on) with the "QuickSort & List" sample on my personal site

Hi Richard,
Your question about "utility classes" brings up a number of issues, all of
which are important to long-term success with Forte.
There is no such thing as a static method (method that is associated with a
class but without an implicit object reference - this/self/me "pointer") in
TOOL, nor is there such thing as a global method (method not associated
with a class at all). This is in contrast to C++, which has both, and
Java, which has static methods, but not global classes. Frequently, Forte
developers will write code like this:
result, num : double;
// get initial value for num....
tmpDoubleData : DoubleData = new;
tmpDoubleData.DoubleValue = num;
result = tmpDoubleData.Sqrt().DoubleValue;
tmpDoubleData = NIL; // send a hint to the garbage collector
in places where a C++ programmer would write:
double result, num;
// get initial value for num....
result = Math::Sqrt(num);
or a Java programmer would write:
double result, num;
// get initial value for num....
result = Math.sqrt(num);
The result of this is that you end up allocating an extra object now and
then. In practice, this is not a big deal memory-wise. If you have a
server that is getting a lot of hits, or if you are doing some intense
processing, then you could pre-allocate and reuse the data object. Note
that optimization has its own issues, so you should start by allocating
only when you need the object.
If you are looking for a StringUtil class, then you will want to use an
instance of TextData or TextNullable. If you are looking to add methods,
you could subclass from TextNullable, and add methods. Note that you will
still have to instantiate an object and call methods on that object.
The next issue you raise is where the object resides. As long as you do
not have an anchored object, you will always have a copy of an object on a
partition. If you do not pass the object in a call to another partition,
the object never leaves. If you pass the object to another partition, then
the other partition will have its own copy of the object. This means that
the client and the server will have their own copies, which is the effect
you are looking for.
Some developers new to Forte will try to get around the lack of global
methods in TOOL by creating a user-visible service object and then calling
methods on it. If you have a general utility, like string handling, this
is a bad idea, since a service object can reside only on a single
partition.
Summary:
* You may find everything you want in TextData.
* Unless you anchor the object, the instance will reside where you
intuitively expect it.
* To patch over the lack of static methods in TOOL, simply allocate an
instance when required.
Feel free to email me if you have more questions on this.

Apache Jakarta Commons FileUpload misleading message

I have a JSP page doing file upload using commons FileUpload package. The code looks like this:
<%
DiskFileUpload upload = new DiskFileUpload();
List items = upload.parseRequest(request);
Iterator itr = items.iterator();
while(itr.hasNext()) {
     FileItem item = (FileItem) itr.next();
     // check if the current item is a form field or an uploaded file
     if(item.isFormField()) {
          String fieldName = item.getFieldName();
          if(fieldName.equals("name"))
               request.setAttribute("msg", "Thank You: " + item.getString());
     } else {
          File fullFile = new File(item.getName());
          File savedFile = new File("c:\\tmp\\",     fullFile.getName());
          item.write(savedFile);
%>
The JSP successfully uploaded the files but it still show me HTTP Status 404 - c:\tmp (Access is denied).
What's wrong with my code? Thank you.

I just found out that the problem that I have mentioned in my previous post has nothing to do with Jakarta Commons Fileupload. It happens whenever I try throwing an exception. And it happens only when I use Internet Explorer
Thanks,
Joe

Jakarta Commons Lang 1.01 vs. 2.0?

I looked through the newsgroup, but didn't see this question come up.
Currently, the latest version of the Jakarta Commons Lang package is 2.0,
though Kodo 3.2.4 includes 1.0.1. Are there any known problems or
incompatibilities with using Lang 2.0 with Kodo 3.2.4? We'd like to only
include the Lang 2.0 package in our application.
Also, the link in the documentation (Appendix F) to the Jakarta pages are
broken:
http://jakarta.apache.org/commons/collections.html should be
http://jakarta.apache.org/commons/collections/
http://jakarta.apache.org/commons/lang.html should be
http://jakarta.apache.org/commons/lang/
and
http://jakarta.apache.org/commons/pool.html should be
http://jakarta.apache.org/commons/pool/
(basically, replace the .html with a /).
;ted

There are no known incompatibilities, but in Kodo 3, we're actually
repackaging all our open-source dependencies to get away from random
appearances of incompatibilities.

Commons HTTPClient : Sending file as well as parameters

Hi,
I want to send some parameters as well as a file in request body. I have been doing this via PostMethod by Commons HTTPClient.
Client Code:
          HttpClient client = new HttpClient();
               PostMethod method = new PostMethod("http://localhost:7080/exchange/receive");
               //Parameters
               method.addParameter("username","test");
               method.addParameter("password","a311xhq23");
               //File
               String strXML = FileTest.readTextFile("C:/in.xml");
               method.setRequestBody(strXML);
               int statusCode = client.executeMethod(method);
               if (statusCode != HttpStatus.SC_OK) {
                    System.err.println("Method failed: " + method.getStatusLine());
               String responseString = method.getResponseBodyAsString();
               System.out.println("Response : \n\n"+responseString);Server Code:
                String username = request.getParameter("username");
              System.out.println("Username : "+username);
          InputStream is = request.getInputStream();
          byte buf[]=new byte[1024];
          int len;
          OutputStream out = new FileOutputStream(new File("c:/out.xml"));
          while((len=is.read(buf))>0)
                 out.write(buf,0,len);
          out.close();
          is.close();Here the file is written successfully but request parameters are null. What could be the issue?
Is it right way to send both parameters as well as file?
In http client I haven't specify content type. So what will be default content type? is it multipart request?
Thank is advance.
Regards,
Amit

I'd say your setRequestBody() call is overwriting the parameters. Read the javadocs of the API to get more details about how they work.
What you are trying to mimic is a multipart request, where you can send a file as part of the request to the server. HttpClient should have capabilities to do a multipart request, and on the server side you can use the FileUpload API to read the file and the parameters back.

Jakarta Commons FileUpload ; Internet Explorer Problem

Hi all,
Environment:
Tomcat 5 ;Apache 2; JDK 1.5.0; Jakarta Commons Fileupload 1.0
OS: Windoze XP
Previously I've used jakarta commons fileupload package to succussfully to upload a file.
However, I am trying to check the content type of the file and throw an exception if its not a jpeg file. The following code works great when I use firefox. But it fails when I use Internet Explorer!
When I supply an existing jpg file on my desktop as the input to the HTML form, the code works fine. However if I enter a non-existing jpg filename, I get a "HTTP 500 Internal Server Error"! I expect to get the "Wrong content type!" message (which my JSP throws as an exception and should be caught by the error page). This problem happens only with Internet Explorer. With firefox, I get the "Wrong Content Type" message as expected.
What could be the problem? Please advise.
Thanks
Joe.

I just found out that the problem that I have mentioned in my previous post has nothing to do with Jakarta Commons Fileupload. It happens whenever I try throwing an exception. And it happens only when I use Internet Explorer

Jakarta commons FileUpload - ServletFileUpload.parseRequest(...)

Hello people. I am using:
# Orion app server (don't ask why)
# WebWork 2.1.7 framework
# Jakarta commons file upload 1.2
While writing a file upload action I am having problems with ServletFileUpload.parseRequest(...) as it always returns an empty list.
Reading related Jakarta FAQ it says "this most commonly happens when the request has already been parsed, or processed in some other way."
I then assumed it was my WebWork interceptor so I took that out but I'm still getting the same problem.
Am I missing something in my JSP, another <input> or something?
Is the request being parsed somehwere else beforehand (maybe a WebWork issue)?
Any help would be much appreciated.
Here is the relevant code...
My JSP<html>
     <head>
          <title>File Upload</title>
     </head>
     <body>
          <form enctype="multipart/form-data" method="post" action="doUpload.action" name="uploadForm">
               <input name="upload" type="file" label="File"/>
               <input type="submit" value="upload" />
          </form>
     </body>
</html>
The execute() method of my action     public String execute() {
          log.info("executing");
          // get the request
          HttpServletRequest request = ServletActionContext.getRequest();
          // check that we have a file upload request
          boolean isMultipart = ServletFileUpload.isMultipartContent(request);
          log.debug("request "+ ( (isMultipart ? "IS" : "is NOT") ) +" a multi-part");
          if (isMultipart) {
               // Create a factory for disk-based file items
               DiskFileItemFactory factory = new DiskFileItemFactory();
               factory.setSizeThreshold(100);
               factory.setRepository(new File("C:/tmp/cms/uploads"));
               // Create a new file upload handler
               ServletFileUpload upload = new ServletFileUpload(factory);
               // Parse the request
               try {
                    //List /* FileItem */ items = upload.parseRequest(request);
                    _uploads = upload.parseRequest(request);
               } catch (FileUploadException e) {
                    log.error("Error parsing request" , e);
               // if the above method doesn't work, use my method :)
               if (_uploads.isEmpty()) {
                    _uploads = parseRequest(request);
          return (_uploads == null) || _uploads.isEmpty() ? INPUT : SUCCESS;
     }My implementation of parseRequest(...) works but returns File objects and I need FileItem objects. I don't really want to use this method but will include it here just incase it triggers some inspiration for someone.
private List<File> parseRequest(HttpServletRequest requestObj) {
         List<File> files = new ArrayList<File>();
         // if the request is a multi-part
         if (requestObj instanceof MultiPartRequestWrapper) {
              // cast to multi-part request
              MultiPartRequestWrapper request = (MultiPartRequestWrapper) requestObj;
               // get file parameter names
               Enumeration paramNames = request.getFileParameterNames();
               if (paramNames != null) {
                    // for each parameter name, get corresponding File
                    while (paramNames.hasMoreElements()) {
                         File[] f = request.getFiles("" + paramNames.nextElement() );
                         // add the File to our list
                         if (!ArrayUtils.isEmpty(f)) {
                              files.add(f[0]);
          return files.isEmpty() ? null : files;
    }

Hi edin7976, just wonder have you got any feedback for this problem?
I really want to push this thread up as I am stuck at the exact same question. Can anybody give a hint?

ALSB - Java Callout (.jar using commons-httpclient-3.1)

Hello everyone,
I'm having a not so funny problem.
I made a Java class, that will be called by a Proxy Service (Java callout). I'm using the commons.httpclient-3.1.jar (+ codec and logging).
Here's the code:
package util.http;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.*;
public class UtilitaireHTTP {
// method used by the Proxy Service
public static String getLastModified (String url){
return getHeader(url,"last-modified");
private static String getHeader(String url, String header){
HttpClient client = new HttpClient();
String lastModified = "404";
HeadMethod head = new HeadMethod(url);
try {
//not working
/*int statusCode = client.executeMethod( head );
if (statusCode == 200){
     lastModified = head.getResponseHeader(header).getValue();
//working
lastModified = "200";
catch(Exception e){
     System.out.println(e);
finally {
// release any connection resources used by the method
head.releaseConnection();
return lastModified;
Here's the problem: Whenever I remove the comment block, test it (it's going to work with JUnit), create a JAR. Import it into ALSB jar resources folder. When I do a Java Callout in a Proxy Service I won't be able to see my method getLastModified. If I put that block in comment, re-do all the export import, I'll see the method in the list.
//not working
/*int statusCode = client.executeMethod( head );
if (statusCode == 200){
     lastModified = head.getResponseHeader(header).getValue();
//working
lastModified = "200";
Anyone knows the solution or problem.
Thank you!
Van

While playing with java callouts i've built working "groovy callout" sample. This way you can keep logic in your alsb proxy service rather than in jar file. Have a look. http://blog.aujava.com/?p=64

Please no jakarta-commons-collections-3.1.jar in Kodo 3.2!!

As far as I know jakarta-commons-collections-3.1.jar is not backward
compatible with 2.x version of jakarta collections. Many things (such as
Struts) are shipped with collections 2.1 and might not work with 3.1
collections. Is it possible to keep 2.1 collections in Kodo. And eventually
get rid of it all together if possible! IMHO jakarta collections (and lang?)
libraries are bad dependency since they can't keep it backward compatible
and went through 3 versions of it in short time

Use servlet filter to clean up your PMs
1. Create Disposable interface
2. Create PMHolder which implement Disposable and make sure when you create
instance of PMHolder you attach it to http request as an attribute (I
suggest passing request as parameter to PMHolder constructor and
autoregister new instance with the request)
3. Create filter which inspects all request attributes and call
Disposable.close() on all attributes which implement Disposable
It will let you create PMs lazily in your struts forms and not to worry
about closing them and it will let you to use PMs directly in your JSPs if
you have to again without worry about leaks

Also commons beanutil have a new version which can run against both 2.1and
3.x codebases. I think there is lots of confusion in thius area. We
trued
our struts apps with 3.1 collections they seem to be ok.
Thanks for the link! It's particularly good to hear that struts seems towork
with 3.1.If it didn't, I'd be in deep trouble. I've got a major webapp using Struts
1.1 which I rewrote using KodoJDO. The only tricky part was allowing for
pages that would gather data from 4 or 5 places (some of them collections)
and push them out to the view, since I needed to release the Persistence
Manager in the Struts Action Processor or I'd either have to put logic on
the JSPs or leak Persistence Managers.
// Disconnect display data from PM so we can close PM.
pm.makeTransient(info);
pm.makeTransient(info.getOfacMain());
pm.makeTransientAll(info.getOfacMain().getOfacAddress());
pm.makeTransientAll(info.getOfacMain().getOfacAlias());
pm.makeTransient(info.getOfacSourceData());
pm.close();
I did have issues about a large browse set, but Stephen Kim set me on the
right track on that one.
Kodo 3.2 Beta didn't have any Struts-related problems either.

Jakarta Commons -- File Upload does not work with Application Server

Hi ALl,
I tried Jakarta Commons file upload. In the netbeans, I copied the common jar files "commons-io-1.2.jar" and "commons-fileupload-1.1.1.jar" in the
netbeans-5.5\enterprise3\apache-tomcat-5.5.17\common\lib and set the class paths. It is working correctly when I compile and run from the netbeans. However, when I deployed in Sun Application Server PE 9.0, I am receiving the following errors. In Sun application I copied the above jars files to "C:\Sun\AppServer\jdk\jre\lib\ext"..
I have read in several postings that it does not work this way but could find any solution. Any idea will be greatly appreciated.

Hi All,
I solved this few minutes after I posted this question. Thought I should share with everybody, just in case some one else need it.
I copied these three files in the folder C:\Sun\AppServer\jdk\jre\lib\ext
1. servelet-api.jar
2. commons-io-1.2.jar
3. commons-fileupload-1.1.1.jar
No need to set any class path.
Thanks
