Need help on java Telephony package
Hello Friends,
I am involved in a telephony software development...and I want to use JTAPI for it...but Iam encountering a very basic problem...Iam having jdk1.3 installed in my PC...but whenever I import the javax.telephony.* package,I get an error 'cannot resolve symbol'...please tell me what is the solution for it...also what changes I need to make in path setting so that I can implement it...ie...which jar file I need to include in the classpath...I would like to know if any good guiding tutorial is available for it on the net...
Ashish
Hello freddyrb!
First, you need to download JTAPI from java.sun.com,
because it don't present neither in the standard jdk nor jre.
But, the JTAPI kit is only a bunch of INTERFACES so
you need some implementation, which Sun didn't (and imho shouldn't) provide.
And the problem is a lack of JTAPI implementations.
The only one i have heard of is a some fake system from alphaworks (http://www.alphaworks.ibm.com/aw.nsf/FAQs/j323engine).
No of hardware providers did gladden us with a JTAPI port (at least as of fall of 2000, the last time i checked it). BTW, if someone knows of any JTAPI-enabled yet not too exotic hardware, let me know, please, serge(AT)zolshar.ru.
As for JTAPI over a modem, i heard of an implementation of JTAPI over TAPI but now the project is dead.

I need help with compiling different packages
I've just downloaded j2sdk1.4.0_03 and when i use
import TerminalIO.KeyboardReader;
it says : package TerminalIO does not exist;
and it also has a problem with KeyboardReader.
Please help me!The TerminalIO is not part of standard java classes. Some one must have given that to you, or needs to give it to you. It might be in a jar file. Without knowing what/where the TerminalIO package is, it is difficult to help you.
If the package is in a jar, then you need to include the jar in your Classpath when you compile. If it is not in a jar, then the directory that contains the TerminalIO directory needs to be in the Classpath.

Hi to all developers,
I have a problem here. Hope you guys can help me!!
Basically, i need to generate a report or charts based on the search criteria.
For example: I do a search for a transaction for the month of May 2005, then it will display my search results and when i click a button, it will be able to generate a chart/ report for the transaction for the month of May 2005.
I hope there is someone that can provide me a url or sample codes/application like what i am doing now to guide me along. At least, i won't be so lost.
PS: Actually, my boss asked me to used SQL Server 2005 Reporting Services to generate charts/reports but the problem i faced is how to integrate my reports that i do to my java application.
Thks,
CelineHow much help do you want?
. . . when i click a button, . . . How well do you understand GUI programming?
. . . my boss asked me to used SQL Server 2005 Reporting Services . . .Are you familiar with the java.sql package? -

ok so i have a midterm and need help this question that is gonna be on the midterm. i dont know how to do it and its worth 16 marks!!!! here it is
the UW Orchestra wants to produce a CD containing all the pieces of music
from its upcoming concert. In order to do that, it needs to calculate the total length of time for the
CD. In addition, the conductor wishes to know which piece of music has the longest duration.
Sample output for the program.
The Swan (3.88)
The Bee (0.98)
Claire de Lune (6.02)
Liebesfreund (3.38)
Ragtime (3.48)
The total time for the CD is 18.74 minutes.
The longest piece is Claire de Lune.
Do not include the HTML that is required to embed the program into a Web page (that is, show
only what you would write between <script> and </script> tags).
[4 marks] In the following space, define a function, Print, that takes two parameters, Title and
Length, and outputs a line of text such that Title appears in italics, followed by Length in
parentheses. The function also returns the value of Length.
For example, Print("My World",30) will output the line
My World (30)
and return the value 30.
Put your JavaScript program for the remainder of this question in the space provided on the next
two pages.
[9 marks]. For each piece of music, your program should input the title of the piece and the
duration (in minutes) for that piece, and it should output a line showing those values using the
Print function just defined. After all pieces have been listed, the program should output the
total length of time for the CD, adding in 0.25 minutes between each piece of music (which is
needed on the CD to separate the pieces).
[3 marks] The program should also output the name of the piece that has the longest playing
time.
Use reasonable variable names, indentation and good programming style. Documentation and
comments are not required, but you may add them to explain any assumptions you might want to
make. You need not check that the input is valid, and you may assume that no two pieces have the
same duration.
can anyone help me out! i would be indebt of ur kindness if u can help me out!This forum is for Java, not JavaScript. The two have nothing to do with each other.
And anyway, this is your studying, so you should try to do it, put forth your best effort, and ask specific questions (on the proper fourm). -

I have a number of java files set up like this:
com.pogo.chess2.Applet, com.pogo.chess2.game.Applet, etc
Now each class file uses the keyword: package followed with its associating directory, for example Applet.class would look like this:
package com.pogo.chess2;
import com.pogo.game.external.b;
How do I create a new java project and properly set the path?
Basically I have all of my java code in a folder called com, which has subdirectories with java files as well. What is a package? How do I set it up using a gui such as JCreator Le? Is there a way to drag the folder com to the project and all the files will load?
Thanks in advance.For package, see
http://java.sun.com/docs/books/tutorial/java/concepts/package.html
The rest of your questions involve details of editor/IDE usage. None of them relate to Java. Read the information or Helps from the product you're using. -

3) Record the sound file in a different bit rate format.
I dont know how to go about it.I really hope you all can help me, or direct me to any resources that may help me. Your help is very much appreciated.
Thank you very much....i found this coding in a website n i not very sure that i understand it.

Need help with Java always get error
hey guys need help
this the problem i get :
I go to certain websites and I get this error with firefox.
This Site requires that JavaScript be enabled.
It is enabled.
This is the one of the errors in java script console with firefox.

I have installed the java script from there home site and did a test and says everything is fine. Any ideas?
please helpHi 49ers,
Sorry not to have any real idea of how to help you out here, but this is a Java forum, not JavaScript.
Some Firefox expert may stumble across your post and be able to offer some advice (I hope they do) but this isn't really the best place to post such questions.

Good luck!

Need Help with Java Desktop CP Icon
I just formatted and reinstalled Windows XP Home SP2 and installed the JRE 1.5.0.02. I usually see an icon in my Control Panel but it only appears in the Administrator's CP which I can reach in Safe Mode of course, but it would be easier to deal with if it appeared somewhere on my desktop/taskbar or CP (I am also an Admin). In Safe Mode I made sure that the right settings were made for displaying, but it doesn't.
I know precious little about Java so I need help here.This forum is dedicated to Sun's Java Desktop System, an alternative desktop operating environment. Try reposting here:

In that downloaded JTAPI I got all .java files too.
Now my Question is : what path or classpath I would have to set so that It will give me the all the description of javax.telephony.Call or Terminal or any XYZ classes or Interface just like if U give javap java.awt.Graphics or java.applet.Applet gives U all the methods and veriable whithin it.
If U got the Question's answer or U have it then reply me at my
yahoo mail : [email protected] with subject ::::to answer to telephony question posted on Sun. by [email protected]

Need help about classpath and packages
I am new to jAVA and trying to learn packages.I wrote a java programme called AccountBalance.java with package MyPack;
I set the classpath as C:\java programs\MyPack.
My java program was compile fine BUT classes were not creating in MyPack folder.
Cananyone suggest how java programs create the classes in ClassPath specified folder automatically.
ThanksHere you want to create your class file in a separate package.
Actually the creation of class will happen at the time of compilation.
So you have to take care about it at the time of compilation.
try this one to compile your source file:
javac <java source file name> -d <targetplace>
the java source file name is your source file name and -d is switch that is used to create the package(directory) and the target place is the location where you want to create your package. if you want to create your package in the current directory then you can simply give
javac <java source file name> -d .
try this one all the best. if it's not working then reply me so that i can check myself and try to find another solution for that.
thank you
bye
