Tv tuner and java

I want to know how to connect a tv tuner with a ecografo, I want to capture the image in my computer from the ecografo usin tv tuner...
Do you know how to do it? please help me...

Well, just for this meant just for this card.....
Doing a whole driver for 1 specific card (
1.-maybe the driver development will take much more time than the app I am trying to have
2.-It would work just for one specific device and I do not want to be limited and thats why I am looking for a java APi that abstracts this complexity.
3.-Is not a commercial APP, I just want to play arround with this idea, and spending all the time doing something that a third party may already have done is unlogical for me. "Why to reinvent the warm water??"
Any way, I found that JMF can do this with VFW cards. But I wanted to know if is there any prefered card to do this, or any programmable capable card with an own sdk and allows me to do this.....

How not to use Cold Fusion and Java

Overview
This write up is intended to give java developers that are
developing ColdFusion applications some beneficial information:
things that are not documented.
Scenario
The company builds enterprise class web application software
for fortune 500 companies. It had purchased a CF 7 based product,
had and existing proprietary J2EE based product, and needed to
integrate the two while meeting a host of new requirements. These
requirements were based on delivering a better user experience,
faster / cheaper integration, increased flexibility /
configuration, useablily, decreasing maintenance costs, the ability
to deploy in either install or ASP models. An initiative was
started to create a new framework that integrated the best of each
technologies. Tactically, this meant that we were to build a hybrid
CF and java application: one that used building blocks (decoupled /
cohesive components) that would allow applications to be rapidly
assembled, configured and deployed. This made sense on several
levels, the team was composed of Java and CF developers, the CF
rapid application development was very productive, there is great
functionality delivered in the CF platform and initial performance
tests showed no cause for alarm
The agreed upon design, based on requirements, and analysis
by both the CF and Java staff has us using CF in the presentation
layer, using a CF based MVC, use of CF based web services. The MVC
was deployed using CFC inheritance for model objects and views made
use of CF custom tags. The internals of the application, used a
rules engine, some proprietary java, ORM, and other J2EE
technology. The initial performance of the system was reasonable.
We pushed on with product implementation.
Then it was time to load test the application, and tune it.
Under load the response times were orders of magnitude slower,
sometimes the pages even timed out.
Armed with our profiler, oracle execution plans and we
charged ahead addressing issue after issue. Note that we took
meticulous care in tweaking the active thread pool and ensuring
that our CF setup was tuned for our application. None of the
observations here are a condemnation of the language; rather they
are aspects that, when considered together, not conducive for
building integrated java and CF frameworks that use a structured /
OO programming practices. Further detail can be provided on
request.
CFC inheritance should be avoided - resolution of variable
scope is expensive even if properly declared.
Since CF creates a class per method under the covers call
stacks become very large, especially if used in a loop. This is
nominally exacerbated by CF calls necessary to set up for the
method call (String.toUpper()).
Nesting of loops and if statements should be kept to a
minimum - the conditional for each lookup of logical operator like
LT, GT are synchronized. Under load this results in thread waits.
Jrun has as single thread pool - both http and web service
requests use the same pool. Under load this leads to thread
deadlock. There are work arounds, but they are painful.
Recursion should be avoided - we had a few recursive routines
and these had to be rewritten.
Custom Tags - should be used sparingly - each custom tag
makes a synchronized call to the license server - (This may be
fixed in CF 8)
Summary
In the end we got the performance to reasonable numbers, but
we ended up moving some code to java (Custom Tags) and getting rid
of 'good programming' practices (Inheritance, loops, etc), mandated
proper variable scoping for those things left over. We prototyped a
sans cold fusion implementation and had an order of magnitude
improvement in performance and number of requests served per
second.
The lesson? Use Coldfusion in its sweet spot: make a query,
iterate over the results and format for display. Extensive use of
structure programming techniques or OO CFCs should be avoided: they
will work but under load - but are better as a prototype. Building
frameworks in CF? Think twice, no three times, and, if you must, be
minimalist.

interesting aslbert123,
Not that I doubt you, but could you answer some questions
about your implementation that was so slow:
1.) Did you put your CFCs in the application or server scope?
2.) Were you initializing your CFCs, via CreateObject or
<cfinvoke>, on every request?
3.) Are you sure that you were properly Var'ing every
variable in your methods? (people typically forget about query
names and loop iterator variables)
4.) Could you give examples of how your inheritence was set
up?
5.) For CustomTags, did you call them the old <cf_tag>
way or the newer, better-performing <cfimport> way?
6.) How did you connect CF to Java exactly?
Thanks,
Aaron

Unable to Sync i-Tunes and Apple TV

Hello. I am writing about my inability to sync i-Tunes and Apple TV. I have read a variety of posts in this forum regarding other users' problems with the same issue and have been unable to solve my own based on recommendations, including exchanging my Apple TV for a new one at my local Apple store, which I did.
My Apple TV is linked to my computer through a Linksys wireless router. The Apple TV is able to connect to the internet as demonstrated by its ability to download movie trailers, access YouTube, and get its software updated. It appears in my i-Tunes (version 7.5.0.20) devices list, but each time I click on sync, nothing happens. I get an error message about opening port 3689 because but that port is not blocked. I've shut down my TrendMicro "PC Cillin" firewall and the same message comes up.
So in sum, the Apple TV can link out to the internet but not back to my i-Tunes. Both are running latest software versions. Here's the best part, before I moved a few months ago to my current home, both worked and communicated fine! After I moved and hooked everything back up the way it was, Apple TV didn't work the same (i.e., did not sync with i-Tunes). Thinking it was a problem with Apple TV, I exchanged it for a new one recently. But the new one has the same problem, so it's not the Apple TV unit.
Any help would be much appreciated.
Thanks,
Ronin703

I had the same problem. I doubt it is the firewall software on your cpu but rather then one on the router itself. On your linksys control panel, go to applications and on the port list enter 3689 to 3689, enter the ip address for your appletv (you can get it from the apple tv or from the DHCP client list under the status tab on the router). Click enable then update. Or, you can simply disable the firewall on the security tab of the router but I would not recommend this. Even after updating, I had to unplug the apple tv to reboot it and then it worked fine.

Whats is difference between Java JRE and Java SDK

Hi,
what is the difference between Java JRE and Java SDK...
i think both of them have the same set of files to be installed...
I am not able to understand where they differ

The JRE (Java runtime Environment) contains just the stuff necessary to run Java and the SDK (System Development Kit) contains the extra stuff necessary (and also helpful) to develop in Java.

What is difference between C# Gzip and Java swing GZIPOutputStream?

Hi All,
I have a Java swing tool where i can compress file inputs and we have C# tool.
I am using GZIPOutputStream to compress the stream .
I found the difference between C# and Java Gzip compression while a compressing a file (temp.gif ) -
After Compression of temp.gif file in C# - compressed file size increased
while in java i found a 2% percentage of compression of data.
Could you please tell me , can i achieve same output in Java as compared to C# using GZIPOutputStream ?
Thank a lot in advance.

797957 wrote:
Does java provides a better compression than C#?no idea, i don't do c# programming. and, your question is most likely really: "does java default to a higher compression level than c#".
Btw what is faster compression vs. better compression?meaning, does the code spend more time/effort trying to compress the data (slower but better compression) or less time/effort trying to compress the data (faster but worse compression). most compression algorithms allow you to control this tradeoff depending on whether you care more about cpu time or disk/memory space.

What is the diffrence between package javax.sql and java.sql

Is javax designed for J2EE?
And when to use package javax?

Hi,
What is the diffrence between package javax.sql and java.sql?The JDBC 2.0 & above API is comprised of two packages:
1.The java.sql package and
2.The javax.sql package.
java.sql provides features mostly related to client
side database functionalities where as the javax.sql
package, which adds server-side capabilities.
You automatically get both packages when you download the JavaTM 2 Platform, Standard Edition, Version 1.4 (J2SETM) or the JavaTM 2, Platform Enterprise Edition, Version 1.3 (J2EETM).
For further information on this please visit our website at http://java.sun.com/j2se/1.3/docs/guide/jdbc/index.html
Hope this helps.
Good Luck.

What is the diffrence between My Runnable Interface and Java Runnable

Hi folks
all we know that interfaces in java just a decleration for methods and variables.
so my Question is why when i create an interface its name is "Runnable" and i declared a method called "run" inside it.then when i implements this interface with any class don't do the thread operation but when i implement the java.lang.Runnable the thread is going fine.
so what is the diffrence between My Runnable Interface and Java Runnable?
thnx

and Java Runnable?
thnxClasses and interfaces are not identified by just their "name", like Runnable. The actual "name" the compiler uses is java.lang.Runnable. So even if you duplicate the Runnable interface in your own package, it's not the same as far as the compiler is concerned, because it's in a different package.
Try importing both java.util.* and java.awt.* (which both have a class or interface named List), and then try to compile List myList = new ArrayList();

Java SE and Java EE

I am a IT graduate and I still need some clarification on the relationship between Java SE and Java EE API. Does EE include SE?
For application development, I know I can use only SE without the EE, but can I use EE alone without SE?
Any good articles addressing my questions?
Thank you very much
R

Java EE in fact extends java SE, its primarily aim is to simplify developing multitier enterprise applications (Java SE provides all the necessary basic libraries etc.)
Because Java EE is an extension of Java SE, you cant use EE without SE - without SE there is no EE.

SSO between Portal and Java WD application

Hi Experts,
I am using CE 7.2 on localhost and I am very new to SAP.
I need to know how can I get SSO between Portal and Java WD. I have a WD application that displays the logged in user using "IUser currentUser = WDClientUser.getCurrentUser().getSAPUser()", as well I can use "IUser user = UMFactory.getAuthenticator().getLoggedInUser()". Both work.
Q1. What is the difference in the 2 above?
Q2. My WD application is set to authenticate user. The WD application is in URL iView. I need SSO between Portal and WD application. Is there a way to get this SSO without SAP Backend (ECC), for now I just need SSO between Portal and Java WD appl.
Everything is in localhost.
Please advice. Thanks.

> need to know how can I get SSO between Portal and Java WD.
Then I suggest you ask your question in the Web Dynpro Java forum instead of the Web Dynpro ABAP one.

My iphone has lost it´s tunes and does only vibrate.By incoming calls it shows "blocked"

By incoming calls my iphone dos only vibrate (no tune) and it shows "blocked".How can I get back the tunes?

Greetings Nefertiti72,
It seems you are experiencing an issue with contact syncing and management. It seems you've removed an email account which contained a number of contacts that are not associated with your iCloud account. I have linked to a knowledge base article which provides more information about iCloud contacts syncing:
Get help using iCloud Contacts - Apple Support
Learn what to do if you’re having issues using iCloud Contacts. For example, you might make changes to Contacts that don't update across all of your devices.
You may want to consider importing the contacts from the email account you removed. You can do it easily by following the steps in this article:
iCloud: Import a vCard
You can import an electronic business card, also called a vCard, into iCloud Contacts. If the vCard contains contact information for more than one person, each contact becomes a separate entry.
In iCloud Contacts, choose Import vCard from the Action pop-up menu , which appears at the bottom of the All Contacts list or a list of group contacts
Select a vCard to import.
The contacts from the vCard are added to the All Contacts group in Contacts. You can add the contacts to any other group by dragging them to the desired group.
Thank you for contributing to Apple Support Communities.
Best,
Bobby_D

J2me and java card, need help to communicate

we are trying to put together a reader to read smartcards using j2me and we figure that it would be easiest if we could develop it to work with java cards rather than standard smart cards, the problem is we get garbage when we communicate to it, the chip sends us crap, any suggestions what might be wrong, any calls we might be missing, has anyone worked with j2me and java cards or smart cards, any help would be appreciated.
einar

.... reader app and the ME behind it .... smells like mobile ....
First of all - if you want to have one mobile application running on this just make sure that whatever is written in ME can use drivers from the reader chip ....
Workin on the PC is something completely different. There was one good example how to develop one host application in Java provided with the JCOP tools long ago ... I don't know if this is now in the new Eclipse tools.
But - there was a small API provided that can give you good hints what to do - and - once you have it on the reader side - you can easily integrate ME methods with this ...

I just rented a movie from I tunes and it is not showing up on my I Pad

I just rented a movie on I tunes and it is not showing up on my I Pad?

Did you use iTunes on your computer, or iTunes on your iPad? If you rented it on your computer, you need to transfer it from there to your iPad. Plug in the iPad, select it in iTunes, and select the Movies tab. A Rented Movies section should appear.

Hi,
Strikes -
Go into compositionReady and have 3 variables you will be able to set them like this
strike1 = 0;
strike2 = 0;
strike3 = 0;
So on the wrong item click have
if(strike1 == 0) {
PLAY STRIKE1 ANIMATION
strike1 = 1;
else if(strike2 == 0) {
PLAY STRIKE2 ANIMATION
strike2 = 1;
else if(strike3 == 0) {
PLAY STRIKE2 ANIMATION
strike3 = 1;
So this will make it so when the wrong item is clicked each strike will be played in order.
Random Scrolling -
You should look into the Math.Random function to make things random in edge.
This is an example of the Random function. It will generate a random number up to 100.
var random = Math.floor (Math.random () * 100);
Lose Screen Score -
So we can create another variable in compositionReady for the lose score.
score = 0;
Now when the user gains a point to add to the score you could do this code on the click
score++;
which would add 1 to the score, However you can add however much you like to the score doing "score + 2" and so on.
To edit a text with the score at the end which I'm assuming you will want to do you will use .html
so $("Text").html("You score is " + score);
I hope this helps!
