Tracking with servlets

Hi,
I've a site the home page of the site is a jsp page,can someone tell me how to track the number of hits to the home page with servlets

why would you want to use a servlet for that. the thing is that using a servlet would mean to issue another request. easier is to use a simple java class residing on side of the jsp which just has a counter being read from /written to a simple file (maybe static methods). from jsp u can just call the class in the beginning...

What is session tracking in servlets?

Hi ,
I'm studying servlets I don't have the clear idea about session tracking and Why and where we need to use it. Can any one say about this.....
Thanks in advance,
Maheshwaran Devaraj

Well Mheshpmr session tracking in servlets is very important...There are a number of problems that arise from the fact that HTTP is a "stateless" protocol. In particular, when you are doing on-line shopping, it is a real annoyance that the Web server can't easily remember previous transactions. This makes applications like shopping carts very problematic: when you add an entry to your cart, how does the server know what's already in your cart? Even if servers did retain contextual information, you'd still have problems with e-commerce. When you move from the page where you specify what you want to buy (hosted on the regular Web server) to the page that takes your credit card number and shipping address (hosted on the secure server that uses SSL), now let me tell you, how does the server remember what you were buying?
Well There are three typical solutions to this problem.
1. Cookies. You can use HTTP cookies to store information about a shopping session, and each subsequent connection can look up the current session and then extract information about that session from some location on the server machine. This is an excellent alternative, and is the most widely used approach. However, even though servlets have a high-level and easy-to-use interface to cookies, there are still a number of relatively tedious details that need to be handled:
* Extracting the cookie that stores the session identifier from the other cookies (there may be many, after all),
* Setting an appropriate expiration time for the cookie (sessions interrupted by 24 hours probably should be reset), and
* Associating information on the server with the session identifier (there may be far too much information to actually store it in the cookie, plus sensitive data like credit card numbers should never go in cookies).
2. URL Rewriting. You can append some extra data on the end of each URL that identifies the session, and the server can associate that session identifier with data it has stored about that session. This is also an excellent solution, and even has the advantage that it works with browsers that don't support cookies or where the user has disabled cookies. However, it has most of the same problems as cookies, namely that the server-side program has a lot of straightforward but tedious processing to do. In addition, you have to be very careful that every URL returned to the user (even via indirect means like Location fields in server redirects) has the extra information appended. And, if the user leaves the session and comes back via a bookmark or link, the session information can be lost.
3. Hidden form fields. HTML forms have an entry that looks like the following: <INPUT TYPE="HIDDEN" NAME="session" VALUE="...">. This means that, when the form is submitted, the specified name and value are included in the GET or POST data. This can be used to store information about the session. However, it has the major disadvantage that it only works if every page is dynamically generated, since the whole point is that each session has a unique identifier.
Servlets provide an outstanding technical solution: the HttpSession API. This is a high-level interface built on top of cookies or URL-rewriting. In fact, on many servers, they use cookies if the browser supports them, but automatically revert to URL-rewriting when cookies are unsupported or explicitly disabled. But the servlet author doesn't need to bother with many of the details, doesn't have to explicitly manipulate cookies or information appended to the URL, and is automatically given a convenient place to store data that is associated with each session.

When streaming a movie with the new Apple TV, and using a DSL Internet connection, all audio sound works, e.g., the music track, but the audio track with the actor's voices, does not work. What can I do?

Hi Brian,
Thanks restoring and restarting didn't fix my problem - i have started it fresh and still it doesn't work. Basically I press ONCE on the remote, after the machine has not had any commands for 10 minutes, and the cursor skips from one end of the menu to the other - so I can't choose network or update software etc - I sometimes manage to stop it randomly in the middle of the menu if I press on a command in the middle of the cursor skipping all the menu steps...not sure what the problem is but I have basically not used my brand new apple tv since I bought it for that reason! I should call Apple support I suppose! grrrr hate wasting time with stuff like this!
Thanks for your help though!

Can't get more than one Ultrabeat sound setting in one project. If I have a drum track with an Ultrabeat "downtempo kit" and I make another drum track with "hip hop kit" in the same project, the settings of the other track transform to "hip hop" setting.

So here's my situation. I'm using Logic Pro 9. I'm trying to use multiple drum tracks each with different Ultrabeat settings. So let's say I have drum track with a loop from Ultrabeat that has the "downtempo kit 2" setting on it. If I make another drum track and create a different loop in Ultrabeat with a different setting, let's say "hip hop kit" for example, and put that loop onto the new track, then the previous loop that I had in the first drum track will still be the same loop but the sound kit settings change to that of "hip hop kit." So I can have different loops, but they all have to be "hip hop kit" settings or "downtempo kit 2" settings. I am unable to multiple kit settings. Is there a box I need to check to turn some automation off or something, because this is pretty inconvinient? Why do I have to have only one Ultrabeat sound/kit setting per Logic project?

Sounds like maybe you're using the same channel strip on multiple tracks? Make sure you're creating a new software instrument channel strip for each independent instance of Ultrabeat you want to have. If you use the same CS, then all tracks that use it will have to have the same kit.

How do you setup a send to a track with multiple effects?

I am just learning how to mix and master songs as well as using Adobe Audition and was wonder if it was possible to allow a track to have multiple sends on them, Lets say one send containing Reverb on one bus, then another send applied to the same track containg delay thus allwoing me to controll idependently how hard the two seperate affects will contribute to the mix.

Audition allows you to have up to 16 sends on each track with a separate level control on each. And you can set up a bus track for each containing it's own effects rack. If you really want to you can use any one of the sixteen sends from a bus to another bus or to the master track.

How can I export an audio track with just the effect signal without the audio?

I want to export dry audio tracks and their effects signals as separate tracks. For instance a track with a reverbed snare would be one track with the dry snare and one with just the reverb.
I know from people who use Reason that it's just a box you need to tick, but I'm struggling to find out how to do it in Logic. Surely it must be a way?

I don't remember Reason being that straight forward, but the obvious way to go, is to mute all sends and bounce.
Then solo the reverb channel, in aux, checking it isn't shared by other sources, and bounce. You should have a dry and a reverbed signal, at your convenience.

How do I create a track with just controller MIDI data in it?

How can I create a track with just MIDI controller data in it?
For example: I'd like to create a track that issues a bank change/patch change and sets the default volume for that track, and that's it.
I can then use this setup as a template for future projects.
How can I do this?
It seems like LPX will not allow me to enter any controller data into a track without first defining a region. However, it seems that LPX also won't allow me to create a region with just controller data in it.
Ideas?
Thanks
-Mike

Let me qualify, I'm using Logic 9, not upgrading for various reasons.
Is this for an external Instrument? If so it's very easy to do using the inspector, but first you have to create an instrument in the environment. (at least in L9 and the way I do it, which is old school) Here's an example of an external instrument setup in the Environment.
A multi Instrument is created, channels 1, 2, 3, & 9 are active. Patch names are entered, format for bank change is selected. (just happens I selected channel 14 to open the patch names). This Instrument will now appear in the arrange page, and you can set patch change, bank change, volume & pan.

In iTunes 10, I could type "Sinatra" in the search file, and would get a list of all tracks with "Sinatra" in any field.   In iTunes 11 I get these clever little windows, with nice arrows, but no lists to view.   What am I missing?

Thanks for chipping in.   I discovered something after trying what you suggested.   I have quite a few collections of hits by year from Time Life and Billboard. I've eliminated duplicate tracks that appear in both collections (or other CDs for that matter), but cross-reference the CD where I deleted the track and placed in in the comments section of the CD track I retained.   If I "search" by song name, only the remaining track appears.   But if I want to hear for example Classic Rock 1964, only those tracks remaining would be there when I pull up that CD.   So, I type "Classic Rock 1964," in the search field. First the boxes on the right of the screen open up showing album icons. Showing four tracks by album with a button to view 10 more, then four songs with an option to vies 18 more.   I finally noticed that at the top of the boxes is a blue band that reads, :Show Classic Rock 1964 in Music. When I double click on this blue band, all 24 tracks from the original CD appear in the song list format even though I had deleted two of them because they appeard in a Beach Boys CD.   On those tracks, I had referenced Classic Rock 1964 in the comments field.    So, bottom line, Search will also look in the comments field if you click "filter by all" in the magnifying glass to the left of the search field.   And you can move all tracks that if finds into a song list by double clicking on the blue band.

Two new SCs in the same track - with dependencies

Hello Guys,
We are going to create an NWDI track with two new Software Components.
1. SC for Services (let us call it SC-A)
2. SC for UI Content (let us call it SC-B)
These are going to be brand new SCs created in SLD and imported into one NWDI track for starting the development.
SC-B is going to be dependent on SC-A.
(SC-B will use various services provided by SC-A which will be made available via public parts).
I will create the SCs in SLD and define the necessary dependencies accordingly (between SC-B and SC-A).
I will then create the track with the above two SCs as developed Software Components.
Initially at the check in stage, I will not have any sources (SCA files) for the above two software components itself (since
they are brand new - without any code yet). However, I will checkin the other required SCAs (JEE, JBUILDT, JTECHS, .. ).
My concerns / questions are:
1. Can we do the development on both the software components in parallel?
2. Let us say, I created a DC with name DC-A in SC-A (via a NWDS activity) and after checking that activity in and activating my changes,
I created another DC with name DC-B in SC-B which uses DC-A from SC-A, would this be a problem?
3. In question 2 above, do I have to take care of the dependencies in a different way ?
(when compared to having both the used DC and USing DC in the same SC)
4. Can I add more SCs into the same track (which will probably use both SC-A and SC-B) in the future ?
I believe that this is going to be just fine but I am a little confused around the initial "check-in" of the requires SCAs into the track.
Also, we are going to spend a lot of time in the development system itself and it would be nice to work in parallel on both the SCs.
(The assembly of the above said SCs is only going to happen after a few months of development effort).
I also understand that we can have the two SCs in separate tracks but we really want them in the same track and be able to work on them in parallel.
Please throw some light in this area ...
Thanks for taking time to read ...
Thanks,
Kalyan

Hi Kalyan,
To your questions:
1. Yes.
2. No, make sure to sync you used DC's on DC-B.
3. No, this is a legitimate SC-DC architecture.
4. Yes, but for "future" projects you probably want to use new tracks.
You should check-in the required SCA's AND import them in development.
You can work parallel on both SC's.
You better use one track as assembly/deployment will be on the same date, otherwise you need track connections (either a repair, which needs a NWDS-release of perhaps not tested functionality, or a transport, which needs a complete & approved SC-A, is it?).
Let me just say: I have the same architecture and it works fine for me.
Hope this helps,
Regards,
Alain

Creation of Track with modified ess/mss SCAs

Hi,
I am in a situation where es/mss code has been changed in production directly without any track.
Now therequirement is:
Creating a new track with the modified SCAs and use that track for future enhancement.
My doubts are:
1. How can I get the modified SCAs to add while creating the tracks.
The track will offer the SCs added in SLD. Will it be the latest one.
Please help
Regards
Arindam

Hi Arindam,
I'm a bit concerned now about the possibility of getting your changed sources into the track:
As you are stating, all deployments were done directly on the production server using SDM from NWDS. This means, that only the builded EAR files are deployed on the server without the sources. With these kind of deployments the SCA files were never affected.
So it will not work!
Some way or another you need to get the changed sources into the the track:
by manipulating the original SCA file with the changed sources and importing it into CMS;
or,
by importing the original SCA file into CMS and upgrading the sources manually.
My advice is the second scenario.
Sorry, but I don't see another way.
Regards,
Alain.

Is there a (relatively simple) way to skip tracks with an iPod touch 5th gen using a physical button? I'm aware songs can be skipped on-screen without unlocking the iPod, but I'm looking for a method that doesn't require taking my eyes off the road.

Is there a (relatively simple) way to skip tracks with an iPod touch 5th gen using a physical button? I'm aware songs can be skipped on-screen without unlocking the iPod, but I'm looking for a method that doesn't require taking my eyes off the road while driving. For that reason, I'm also not interested in adding in headphones or additional devices that have the desired button functions. Going both forward and back would be great but I would be pleased just to have a "sight-free" way to go forward.
I've seen some mention here and there about ways to maybe change it so the volume buttons change tracks and holding the volume buttons changes the volume... but I don't know what's involved in that or if its even possible/recommended for a new 5th gen iPod. I think its a great device but its sadly lacking in music oriented functions and features... which is disappointing since music is why most people would bother getting one instead of some other "iDevice" :/

Given that you cannot do what you have asked for, perhaps you simply need to find another solution to your root problem.
Presumably, you want to skip to the next track because you don't want to hear the current one, and that is because...
You don't like it.
You've heard it recently and don't want to hear it now.
Simply don't want to hear it at this time.
For problem number 1. Don't put it on the iPod in the first place. (I know, obvious answer!)
For problem number 2. How about playing from a Smart Playlist (initially created in your iTunes Library) which has only songs you've not played recently?
For problem number 3. Hhhmmm! Create alternative Playlists for use in the car.
As for going back to the start of the "now playing" track.... Well, if your Playlist has only songs that you really, really want to hear, then you'll be looking forward to that rather go back to the beginning of the current song.
I'm not trying to be prescriptive, just giving you food for thought.
(They are all cheaper options than buying a car which can control the iPod from the steering wheel.)

Sound Stutters when i select track with music in it, Resolution Problem?

Hello
Im having a bit of a problem with logic 8, i had this problem in 7 as well and i figured it would be resolved when i upgraded but alas no love. Basically when i select a track that has somthing on it in the sequencer window a l the sound starts stuttering and i eventually get the following error message
Could Not synchronize audio and midi
Sample Rate 34597 recognized.
Check conflict between Logic Pro and external device.
Now i looked this up on the logic support page and it says theirs a method of reseting all the sample rates in 7 but i am unable to find this in logic 8.
Please please help me with this as i am unable to play anything using midi or to properly work in general and i have several projects due.
Many thanks in advanced

I have a m-audio fire wire audio device but i am not using it right now. Only when i want to record thngs. As for external sync modes or clocking from a digital source to my knowledge i am not. Is their a method i can check to see if im doing this?
I have the feeling its nothng to do with the buffer sizes as the strange thing is that sound will play fine so long as i have selected a track that has nothing on it. Its only when i select a track with either audio or midi in it that the sound starts stuttering. Also the fact that its detecting a sample rate of 34597 seems a bit strange as logic works on 41.1.
All very strange. Im thinking it may have somthing to do with the midi device settings as its only when i select a track that im getting this stuttering so perhaps logics sample rate settings on the track change when its receiving input from the midi controller?

How to download the same song(track) with different keys? iTunes seems to think I have already downloaded the song and will not download the song in a different key of the Demo Track

How to download the same song(track) with different keys? iTunes seems to think I have already dowloaded the song and will not let me download the song in a different key or the Demo.

Hello Jigz19,
It sounds like you are unable to play a couple of songs from your library becuase you get a message that the computer is unauthorized to play, but other content purchased that same day works without issue. I would verify that the affected songs were purchased with the same Apple ID first:

http://support.apple.com/kb/ht1920
Open iTunes
Highlight one of the items you have purchased (You can find your purchases in your Purchases playlist).
Choose File > Get Info.
Click the Summary tab.
The Account Name area will list the account used to purchase the item. Unless you have changed accounts, this is your iTunes Store account name.
If so, then delete the songs:

Communicate with servlet after using Java Web Start?

Is it possible to communicate with servlet to get data back and forth
after using Web Start to download the client application?
The demos come with Java Web Start are applications which are
standalone, don't need communicate with the servlet on Web server
after being launched. I am wondering if it is possible, and how (HTTP
& JAX-RPC)?
Thanx in advance.

I've done this using HTTP. I get the server and port from the codebase:
BasicService bs = null;
try {
bs = (BasicService)ServiceManager.lookup("javax.jnlp.BasicService");
String codeBase = bs.getCodeBase().toString();
and use the java.net.HttpURLConnection and java.net.URL classes to send HTTP parameter values to the servlet and to receive results from the HttpURLConnection's input stream.
