WebDAV J2ME client

hi
subject really says it all - i'm looking for a WebDAV J2ME client and would appreciate any help/guidance this forum can provide.
without getting into the specifics of why i need one - assuming one is not available, is it possible to implement one ?
thanks
dave

Sure it's possible!
Read there RFC's and get going:
- http://www.ietf.org/rfc/rfc2518.txt
- http://www.ietf.org/rfc/rfc3253.txt

Webdav using Client Certificates

Hello all
Finder (10.5.6) seems not to be able to use Webdav with client certificates. Especially in conjunction with Alfresco Share this would be nice.
Any ideas?

Hi,
> have a question, if we use this mechansim do we have to mainatin User's cerificate in user master or >this is not needed as we are accepting the connection from the intermediary server which is trusted by >the J2EE engine.
I think it depends from your Biller Direct application.
In my company we use Rosettanet B2B with SAP XI and have this setup :
Internet -- https --> Apache -- https --> Web dispatcher -- https --> SAP J2EE PI
The client certificate from the B2B partner is sent up to SAP PI and we did not have to set the certificate in the user mast.
We did have to import the certificate in the J2EE keystore and to configure the Rosettanet connector.

Bluetooth communication between J2SE server and J2ME client

Hi everyone!
I'm new here in this forum...
I try to make a small project to my studies,
My project will include J2SE server and J2ME client.
I'm stuck in the step of finding the server with the wireless toolkit emulator.
I found this issue in old subject: here
I try the solution in reply 6 but I don't understand exactly who to define kvem.home, and I got this error:
" You must define the system property "kvem.home" "
maybe someone can help me and explain how to do that?
thanks!

Hello,
I want to find out how this can be done, too. I tried with
System.setProperty("kvem.home", "C:\\WTK2.5.2");but I get an error:
java.lang.UnsatisfiedLinkError: com.sun.kvem.jsr082.impl.bluetooth.BluetoothController.setSystemProperty(Ljava/lang/String;Ljava/lang/String;)I included these files in the build path:
c:\WTK2.5.2\wtklib\gcf-op.jar
c:\WTK2.5.2\wtklib\kenv.zip
c:\WTK2.5.2\wtklib\kvem.jar
and I import com.sun.kvem.bluetooth.*;
I'd appreciate any help.

Bluetooth simulation between J2SE server and J2ME client

hi there,
I have a working bluetooth client/server application (using BlueCove), with the server on a PC (the PC has bluetooth hardware) and the client on a mobile telephone.
I wish to move the application to a bluetooth simulated environment, however.
To simulate bluetooth between 2 mobiles, I could open 2 instances of the WTK simulator and the mobiles will find each other -- but this doesn't meet my needs. I wish to simulate the bluetooth environment between a J2SE server and a J2ME client.
Can I do this using the wireless toolkit? Does anyone have other ideas?
thanks,
Manoj

OK - I have the solution.
My PC (server) code used BlueCove to talk to the bluetooth stack. The trick is to use Sun's own KVM packages. This creates a virtual bluetooth device on your machine, shared by the WTK emulator.
Here's the server code:

               server = (StreamConnectionNotifier) Connector.open(url);
               this.logMessage("waiting for connection...");
               StreamConnection conn = server.acceptAndOpen();
               this.logMessage("connection opened");
               InputStream is = conn.openInputStream();
               byte buffer[] = new byte[1000];
               while (true) {
                    int numChars = is.read(buffer);

               this.logMessage(e.getMessage());
}You need to include the location of WTK as the kvem.home define. If its installed in c:\wtk22 (the default), start the server with the parameter -Dkvem.home="c:\wtk22". You also need to include these 3 libraries:
c:\wtk22\wtklib\gcf-op.jar
c:\wtk22\wtklib\kenv.zip
c:\wtk22\wtklib\kvem.jar
That's it for the server. My code of the sample client (the mobile phone, running in the WTK emulator) is messy (sorry about that -- still cleaning it up)!

...and that's it. Start the server, then the client (all on the same machine) and you've simulated bluetooth between the 2.
To get the server working with a real mobile, you'll need to use the BlueCove library instead of the 3 WTK jars (and can remove the kvem.home directive as well). The rest of the code should remain the same (haven't quite tested that yet!).

Getting User-Agent through J2ME Client

Hi, i think most of the developers here might have come across this problem.
I have a servlet that will get the client's User-Agent headers value when the client access it. When i access the servlet through a phone browser, the header will give me the phone's user agent. But when i access the same servlet through my J2ME client, the header will return a value of 'UNTRUSTED/1.0' string which doesn't contain any user agent info.
I understand that in JSR implementation the 'UNTRUSTED' string will be appended to the User Agent header, but the original user agent value is not there. Does anyone knows what is the reason behind this?
Thanx.
FooShyn

first:
- do not multipost the same message
second:
- did you put headers on your connection in your application?
- and the only useragent that you can get is the useragent defined in the app...
for example:
try {
      c = (HttpConnection)Connector.open(url);
      c.setRequestMethod(HttpConnection.GET);
      c.setRequestProperty("IF-Modified-Since", "10 Nov 2000 17:29:12 GMT");
      c.setRequestProperty("User-Agent","Profile/MIDP-1.0 Confirguration/CLDC-1.0");
      c.setRequestProperty("Content-Language",      "en-CA");
      os = c.openOutputStream();
...taken from http://developers.sun.com/techtopics/mobility/midp/articles/network/ThirdExample.java

Chat between j2me clients and using a Servlet server

Java gurus, please help me..
I'm wondering if I could set up a sort of chat functionality between two j2me clients. I wish to use Java servlets as my server and Tomcat to deploy it. Is this possible? Can i do these by using http connection only or do i have to use sockets? If i use sockets, how will i configure Tomcat, or do i still need Tomcat?
Hope someone could help! Thanks in advance! =)

Basically it means you should have a Thread that loops and make an http request every x seconds. Before sending the request it should check if the user has typed anything, and send that with the request. The server should keep track of all the chat messages sent, and forward to all the other clients when they request an update. To keep track of what clients have received what messages, you could have a time stamp for each message, and a "last update" field for each client.
The client should run something like this in a thread:
while (iAmRunning) {
url = "......." // address of your server
if (the user typed anything since the last time we sent a request) {
    url = url + "?msg=" + whatTheUserTyped; // maybe another parameter for private messages?
    reset what the user typed (so it won't be sent next time);
send the request;
get the response containing what the rest of the users have
    typed since my last update;
update the display with the latest messages;
}And the server would handle a request like:
if (the request contains a message) {
save the message with the current time;
check when was the previous update for this user;
get all messages where the timestamp is later than the last update;
set the last update field for the user with to the current time;
respond with all the messages;

Information transfer from J2ME client to WLS 8.1 sp3 thru' SSL

Hi,
We are planning to have a J2ME client (CLDC 1.0 and MIDP 2.0) to transfer information to Weblogic server 8.1 sp3 through SSL. We are planning to use Verisign certificate at the Weblogic server to implement the SSL communication. Could you please let me know if there is any issue?
I came across from BEA web-site
(http://e-docs.bea.com/wls/docs81/notes/issues.html#1278025)recently that J2ME clients have certain issues to talk to WLS. That page says:
Web Services Known Issues
Change Request Number CR107595
Description
SSL does not work for J2ME clients on WebLogic Server 8.1.
Certicom SSL libraries require additional features that are not supported by J2ME. Therefore, SSL is not supported for J2ME clients on WebLogic Server 8.1.
That is why I am little apprehensive. Please advise.
Thanks,
Goutam.

1) sorry, there is no official solution of "1999 schema" problem that I know of.
2) if the service is not changed, there is no need to re-create call or stub object for every invocation.

Webdav with client ssl certificate

I have created one webdav enable site in apple mac mini server using apache. The webdav site is secured with https as well as client certificate.
While browsing the website using safari/IE everything is working fine,but with ipad's webdav utility it is not working.Client cert is not picking up by webdav nav tool, although the client ssl cert is installed in ipad.

Some more checking using wireshark on the destination server.
I created a simple html page that is contained under a directory that requires SSL and a client certificate, as configured in the apache configuration.
This works fine from the IE and Firefox desktop browsers.
Now, using Safari on the iPad with the appropriate certificates installed (client cert and CA cert) using the profile management tool, I attempted to connect to this page.
Wireshark shows the iPad contacting the server and the TLSv1 protocol selection (Client Hello and Server Hello).
Following this the server issues the requested server certificate and the CA cert to the iPad device.
The iPad device responds with an ACK and this is where it stops the communication. No further packets appear.
During this time, the iPad has requested that a client certificate be selected using the dialog and the appropriate client cert is selected, however the network transaction does not show the iPad ever sending this certificate to the server.

J2ME client server

Hi i have a client J2ME application written verifyed and running. I am a little new to the whole programming thing but I was wondering if anybody knew if it was possible to use JSP or a servlet to distribute an application like a quiz on my server, package this into a midlet and then send it to a client and then return the results in either sms or an e-mail format using a pop3 connection
I think it is possible to do this in WML format. I know this would be more practical as the results would just be looked up in the browser of the deivce and these would link to the database. However I am having trouble setting up the server. I am not quite sure how to go about it.
I have downloaded tomcat 4.1 and i have just run it on the default localhost port number. But I am not sure where to go from here. I tried to write a servlet to deal witht the application request but I am not sure how to setup a database or the files I want downloaded for OTA provisioning. I have the WTK2.0 beta with OTA. I tried uploading the final jar and jad files to my public web space but I guess since there are not supportive mime settings this will not work.
Any advice or help would be greatly appreciated for a dummy programmer.
thanks,
Prashant

I have managed to configure tomcat properly so far and am interested in a server that can discover the IP addresss of a device using a midlet.

Connection speed on j2me client

Hi,
Can anybody tell me how can I calculate connection speed (or bandwidth) on mobile device using j2me (midlet)?
I know that I can measure ping to the server, but this is only one thing. I also need to know how strong is the signal in my current position in the gsm cell. Is it possible get this information using j2me?
Thanks in advance.

Generally: no. Only devices with the ATCommand api have access to these properties, and there are not a lot of devices that support this.

A listening J2ME client ???

How can I implement, that a Java client listens for incoming messages (HTTP, UDP, WAP) and reacts to them? I want to build a database which can be accessed from many users using their Javaphones in some way. If some user changes data, all other connected Java clients should be informed and updated.
Does that work with WAP PUSH? I realised that the MIDP/CLDC provide UDP, that offers the DatagramConnection interface which can be used in server and in client mode.
Has anybody some good ideas?

Hi,
You'd better read " Advanced MIDP Networking, Accessing Using Sockets and RMI from MIDP-enabled Devices " article on http://wireless.java.sun.com/midp/articles/socketRMI/.
This article:
Gives you a brief overview of CLDC and MIDP Networking
Discusses a middleman architecture for using sockets, RMI, and other Internet services
Shows you how to use sockets from MIDP-enabled devices
Shows you how to send emails from your MIDP-enabled device
Shows you how to use RMI from MIDP
Take care,

How to make a WORKING J2ME Web Services client?

Hi everyone,
I'm trying to make my first J2ME client for web services (well, I need it for my degree thesis, so I'm a little bit DESPERATE) but I've got a lot of problem that I don't understand, even with samples downloaded from web tutorials and from xmethods.net.
The problem is with the generation of Stub classes:
if I try to make the Java Wireless TollKit 2.2 to generate them and then I run the midlet in the JWTK emulator there's no problem, but when I try to do the same thing with the Nokia Developer's Suite 3.0 I've got a lot of problems, first of all the java code generated for the stub is very different from the first one, it seem like a C# or J# code (and obviously Eclipse says that it's full of errors), so when I try to make the jar and jad files it doesn't work (because is not a right java code), so I made the stub classes using the JWTK2.2 Stub Generator and then I used the Nokia Dev's Suite 3.0 to build and package the midlet, but it says that it's not able to find the "class or resource javax/xml/rpc/Stub" even if the resource is present and used exactly as all the other packages, and it creates a jar file with just some of the classes but not all. At the end I tryed to run in the nokia emulators the midlet created by the JWTK 2.2, but it doesn't start, so I put the midlet on two diffent Nokia phones (6600 and 6630, because I need to make my client work on the 6630) but it seems to make the virtual machine to crash. I erased all the code lines invoking the stub classes and added them again one by one, until the midlet stoped again to work, and I understand that the problem seems to be with the invocation of the costructor of the stub class, but it doesen't make no sense, because the same code works properly on not-Nokia phones and emulators. I used many different wsdl files to create the stub classes for different web services, but there's always the same problems.
Help me please.

You will find some working code at :

It's code that use kSOAP and kXML implementations ....

Web service client in J2ME

Hello there, I'm a student and new to web services.
Somehow I manged to setup a plain old java web service using Axis2, and I have tested it with an J2SE RPCclient.
However, what I need to do is to have a J2ME client, and from some searching I have found out about KSOAP. Is there other alternatives, or can I just use AXIS2 RPCclient in J2ME?
I know that I don't need to use java to invoke a java web service, but it's the only think I know that is widely support on phones.
Any advice is appreciated, thanks alot!

Thanks for that link on JSR-172!
One question though.. is it advisable to create a RPC client without using stubs? I don't quite like the idea of stubs and the code it contains.
I did my axis2 J2SE client without stubs, but I can't seem to find any tutorial on JSR-172 that doesn't use stubs.

OSX 10.9 - Mavericks webdav client broken

My company provides a webdav server solution for OS X webdav clients.
Since OS X 10.9 upgrade, many webdav actions including dragging a file onto a webdav mount using Finder and editing files using MS office applications (Microsoft Word, Office, Powerpoint) have stopped working.
Looking at client <-> webdav server traffic, it appears that after acquiring LOCK on a file, client is not supplying lock token in subsequent requests to server, resulting in 423 responses on subsequent operations.
According to webdav spec, client needs to supply file lock-token in subsequent commands to server.
At this point, webdav mount also gets disconnected with following error in dmesg.
Sandbox: QuickLookSatelli(41334) deny network-outbound /private/tmp/.webdavUDS.YlINRf
webdav_sendmsg: sock_connect() = 1
webdav_close_mnomap: no cache file
webdav server: https://server.com/webdav/: connection is dead
webdav_sendmsg: sock_connect() = 61
webdav_sendmsg: sock_connect() = 61
I confirmed that this is not a problem with 10.8 or earlier versions.
Has anyone else seen this problem and have a solution ?
Thanks

What do you mean by "you are going to have to go deeper than that" ?
Would it be possible for you to pm me a test account on your server ? I can then test my Mavericks against your server to see if this issue shows up.
I just mean that something like this requires additional supporting evidence. I was looking for the HTTP headers, which you provided.
My server is inside an application. Hopefully it will get approved and be in the Mac App Store any day now. Unfortunately, I have heavily dependent on the Finder working correctly on the reviewer's machine. As you know, such things are not guaranteed. Send me an e-mail and I will give you either a promo code or a test iTunes account, depending on my luck in the next 48 hours. You can crank your LogLevel to 9 and fill your console.app log - no Wireshark required.
However, you may need to go quite deep with this one. I looked at the webdav client code for Mavericks, and I just don't see any way for it to not include the Lock-Token. This is the only place UNLOCK is ever sent from. The C++ style comments are from me.
int network_unlock_with_nodecache_locked(
struct node_entry *node) /* -> node to unlock on server */
          int error;
          CFURLRef urlRef;
          CFStringRef lockTokenRef;
          char* locktokentofree = NULL;
          uid_t file_locktoken_uid = 0;
/* the 2 headers */
          CFIndex headerCount = 2;
          struct HeaderFieldValue headers[] = {
                    { CFSTR("Accept"), CFSTR("*/*") },
// Apple seems to think this is required.
                    { CFSTR("Lock-Token"), NULL },
                    { CFSTR("translate"), CFSTR("f") }
          if (gServerIdent & WEBDAV_MICROSOFT_IIS_SERVER) {
/* translate flag only for Microsoft IIS Server */
                    headerCount += 1;
          locktokentofree = node->file_locktoken;
          node->file_locktoken = NULL;
          file_locktoken_uid = node->file_locktoken_uid;
          node->file_locktoken_uid = 0;
/*unlocking the node cache before calling send_transaction()*/
          unlock_node_cache();
/* create a CFURL to the node */
          urlRef = create_cfurl_from_node(node, NULL, 0);
          require_action_quiet(urlRef != NULL, create_cfurl_from_node, error = EIO);
// Code obviously copy and pasted from network_delete() function.
/* in the unlikely event that this fails, the DELETE will fail */
// Event if locktokentofree is null or empty, lockTokenRef should still have a
// non-null value.
          lockTokenRef = CFStringCreateWithFormat(kCFAllocatorDefault, NULL, CFSTR("<%s>"), locktokentofree);
// Don't even send the message if lockTokenRef is null.
          require_action_quiet(lockTokenRef != NULL, CFStringCreateWithFormat, error = EIO);
// Lock-Token gets a value here. Is there some value that will make
// CFHTTPMessageSetHeaderFieldValue drop the header entirely in send_transaction()?
          headers[1].value = lockTokenRef;
/* send request to the server and get the response */
/* Note: we use the credentials of the user than obtained the LOCK */
          error = send_transaction(file_locktoken_uid, urlRef, NULL, CFSTR("UNLOCK"), NULL,
                    headerCount, headers, REDIRECT_DISABLE, NULL, NULL, NULL);
          CFRelease(lockTokenRef);
CFStringCreateWithFormat:
          CFRelease(urlRef);
create_cfurl_from_node:
          free(locktokentofree);
          locktokentofree = NULL;
/*Locking the node cache as the function returns a locked node*/
          lock_node_cache();
          return ( error );
The only real difference between the Mavericks code and the Mountain Lion version is that Mavericks has better thread safety. Mavericks pulls values from the node and sets the final node values right away, sending the old values over the wire. If send_transaction() fails or hangs, then the node is still unlocked and other routines can access the node.
I think you should look at all of your messages and find where the Lock-Token no longer gets included. Still, I don't see how it is even possible. If there is some header value you can provide such that CFHTTPMessageSetHeaderFieldValue does not create the header, then that would be your bug. It seems to handle null just fine and would emit "<>" on an empty string, which would still be a valid header.
