Can Java do this job?

Hi all,
I just thinking about writing a program that can display the caller ID.
The problem is:
When a user using dial-up access the internet, the program can detect the caller ID if somebody dial the user's number. Of course, caller ID can be displayed at anytime when somebody calling the user.
I don't know which Java API can be used for this program and how to start writing this program.
Please can you give me any suggestion?
Thanks in advance.
Leo.

If you are talking about having someone call the computer through a modem and the local computer's modem answering it, then you can do JNI calls to packages for caller ID. If you are talking about getting the phone number of people browsing across a website--then you better learn how things operate: it is not possible (to my knowlege) no matter what language you use.

Can java complete this mission? If it can, how?

please, Tell me about your oppinion.
I want to make a applet which can control all opened windows [application] on windows O/S.
In other words, this applet makes the explore which downloads this applet the most top window layer.
So, When user change the active window using mouse or alt-tab, it doesn't works.
I want to use this applet in the examination system. So, when the students show the page which contains this applet, the applet is downloaded and make the PC like dummy terminal during the user see this page.
Can java do this? If it can, how i make this applet?
Umm.. thanks for your reading.

You can look at java.awt.Robot.
If that doesn't do what you need then you will have to figure out how to do it in C/.C++ and then use JNI to connect it to your applet.

Can Java do this

Hi,
I want to really learn Java after just taking classes to this point. I have a task I need to do, but cannot figure IF I can do it in Java, let alone how.
I have about 40 tools on my SGI. They are written in Fortran, C, or a commbination of both. Their code varies from a few lines to 200 or so source files. The machine is networked to other SGIs and Suns, but has no internet connections. My manager wants a top level GUI written to access these tools and to provide information about them.
Can this be done in Java without rewriting all of the tools?
I see that I need to be able to either:
1) Spawn a process (i.e. tell the system to run a given tool) from my Java top level GUI or
2) Write a small java interface for each tool and be able to compile that Java with the C or Fortran code.
Can you do this in Java? If so can someone suggest a book or website to send me in the right direction?
Thank you

Thank youYou can do number one, however this will have to be a system dependent implementation. We have created java applications that can launch non-java applications. It's a little messy but can be done pretty easily.
As far as number two goes, that sounds like a real mess.

What is the logic behind not wanting to use the two easiest approaches to this migration? DTS and the Oracle Migration Workbench are specifically designed to accomplish this sort of task.
You can certainly use the generic connectivity of Oracle Heterogenous Services to connect to a SQL Server database from Oracle, but you'd have to write your own replication code. Heterogenous Services also isn't trivial to install and configure-- if this is a one-time migration, using a tool that's designed to integrate heterogenous databases probably isn't the easiest option.

Can Java replicate this?

Hello,
Back "in the day" many of us enjoyed the Infocom text adventures (now called interactive fiction.) The one thing that made the games very fun to play with was the "recognition" of english speech. The programs were very smart about taking what you typed in and applying the appropriate response (allowing for the fact that you followed the rules).
I would think that Java could mimic this but I want to make sure before I attempt to build an interactive fiction game in Java. Granted I have no idea how to go about it, but that's another story!
Also, how suited is Java to deliver a finished retail product of this sort - whether by download or off the shelves at best buy?
Thanks
Tom

Yeah, I have actually heard of Google, thanks.
My point in asking in a forum was to get some people
who are familair with Java and get their insight
directly.
So it's more a matter of can I figure out how to do
it - Java should be fully capable. Thanks.Java is definitely fully capable, although there are already existing scripting languages that may be even easier. If you do choose Java, however, there are a great many resources to help you get started....

Can java provide a follow/depend/attatch compiling warning?

I wrote a class called Query.It connect to database and return ResultSet.So user must manually call my method close() to close the ResultSet and Connection, otherwise resource will be avaliable.
But user maybe forget call the close() method.If codes are released,problem will occur.
For this reason I want java provides a compile warning if a important method is not called.
e.g. Codes maybe like this:
/**Start**/
class Query(){
ResultSet getResultSet(DataSource ds){
//Codes get resultset
return ResultSet;
void close() follow getResultSet(DataSource){
//Close databse
//Note: "follow getResultSet(DataSource)" is my idea.
class test{
Query query = new Query();
RsultSet rst = query.getResultSet();
//query.close();//#1
/**End**/
If user forget writing line #1 (to close Database,etc), java compiler will give a warning:
The method close() must follow method getResultSet!
You will get error when running.
Can java provide this function?
Thanks!

to mchan0 :
I konw you mean I can copy ResultSet to another Object.But if databse is very very large,ResultSet will use large memory.It is not we want.
e.g. our project database need to store 40,000,000 records.Once load large numbers records,server will crack.
So I can only use ResultSet.
If I wrong,please correct me.
Thanks

Can Java save straight to EPS or similar?

Thanks for reading, heres the setup--user visits my site to design his own custom plaque-he picks a template in my hypothetical Java app and sets to work entering names, congradulatory text and picking from pre-defined graphics/logos and then clicks the ORDER button.
Can I export his design intact to my server in an EPS or similar, common vector file format? Preferably converting some of the type to curves in the process.
I don't want to go through a lot of BS to get the file (as with Flash)--I can't run the output through some third party interpreter and get a sorta-kinda-like representation of his design--it's gotta be THE WYSIWYG design he produced. Reason being we're trying to avoid the layout-proof-update roundtrip--what he designed is exactly what we produce and if there are any mistakes they are his, not ours. (It may sound harsh but it's the only way we can possibly compete anymore--we need to offload the design process 100% onto the customer)
So, can Java do this? Can I get an EPS or similar format straight out of a Java app?
Thank you.

Can Java create HTML tables without running a web server?

Hello,
I would like to know if Java can output data into a simple HTML-like table without having to run a web server or jsp etc.
I want my program to access a database and print records in HTML-like table cells.
It is actually for an events calendar program, where each event would be printed in a cell (date). There would be a variable number of events per cell (date), with each one being editable.
I have seen various "web" calendars like this but I want to make it a desktop application so that it is not dependant on the functioning (or non-functioning!) of a web server.
Can Java do this? I would settle for any type of prewritten table creator (not necessarily HTML) but I do not want Excel type tables or a table where entries must be GUI buttons, such as in Outlook.
Thank you very much for any idea you may have,
Cat

Thank you for the replies :)
I found something with Jeditorpane (JTextComponent and HTML Text Display) at
http://msp-of.de/oreilly/books/javaenterprise/jfc/ch03_21.htm
which looks like what I want. It allows hyperlinks within the table cells and I'm not sure if JTable allows for that. Also, I will want multiple lines and even images (eg moon phases for the calendar) in each cell. I ran the example above and it works great. And yes, it makes use of the HyperlinkListener.
I don't want to create an HTML file for those who suggested that. I just want the flexibility of HTML formatting withing my standalone Java application.
I am still not sure why everyone is suggesting JTable though :) So I will look at it some more. The link above also has a turorial on JTable and does say its faster that JEditor pane because it doesn't have to do any HTML rendering. But it doesn't look to me like it can really ever look like a calendar.....
Thank you again! Being a total Java novice, I am very impressed with how easy JEditorpane is.

When uploading my formatted resume to my Apple Jobs profile, I am always presented with a c:\fakepath message and the resume does not upload. How can I rectify this?

When uploading my formatted resume to my Apple Jobs profile, I am always presented with a c:\fakepath message and the resume does not upload. How can I rectify this?

Add this one to the list of thinks that don't work on the Apple Job Board. It looks like Apple is using ADP's VE (Virtual Edge) technology to run this system, and I've been stupified by the number of features that are just broken, or so poorly thought out by ADP as to be unusable, (certainly for webkit and mozilla browsers at least: I didn't bother checking IE.)
Here are a few highlights:
"My Job List", list of jobs applied for, seems to max out at three. You can apply for more than that, but you can only see the first three.
"Search Using Your Resume" feature yields few or no results, even when the pasted text contains only common, exactly matched words like 'Design' or 'Engineer'.
The missing resume upload, described in this thread.
"My Job Agent" seems to never flag anything, at least it hasn't ever for me despite pretty loose criteria.
Agent's created using "My Job Agent" eventually just disappear, which is fine because they don't seem to work.
When updating a profile, acknowledging the 'Terms' happens twice in a row.
Job seekers can only supply one cover letter despite being able apply for several jobs.
Pagination for search results only appears at the top of the page, so it's necessary to scroll down through each page, then up to the top again to proceed to the next page.
Well, I'm sure there are others, but you get the idea. I hope the Apple folks can fix this, (or twist ADP's arm to fix it,) so it better represents the quality of experience that Apple is so respected for consistently delivering.

Can Java be used for this?

Hi. As a hobby, I have built a game with a development tool called Macromedia Director.The game is a 'virtual tabletop' that allows people to play a variety of role playing games over the internet that are traditionally played in a face to face setting at a real table.
Due to some shortcomings with Director I am looking for another language to program the game.I currently use an old version of Director and upgrading is expensive. Director also has limited cross platform support (no Linux). Finally, the future of Director is in question as Macromedia was acquired by Adobe and they have already end-of-lifed some of the acquired products.
My game consists of some basic features. One user runs a server application that accepts connections from the client application. Once connected the cleints can do basis text chat. There is die rolling function. Finally there is a feature for the referee to send pregenerated images to the players, typically some sort of map. The image can be hidden from the players and revealed in pieces by the referee. I also plan on adding a shared whiteboard feature for creating on the fly images.
I have done some preliminary investigation and it seems that Java is one of the obvious choices. The socket programming seems to be straight forward and allow you to create a similar client/server application. Swing covers building the GUI. What I am not clear on is the graphics capability of Java. Director has a fairly powerful graphics engine allowing you to work with 32 bit graphics (alpha channels) and pixel manipulation.
It seems like Java can do all this, but I want to make sure before I invest to much time. You can see screen shots of my game at http://www.v-fort.org. It's definetly not a polished product. There are many of these types of programs already.I just do it because I enjoy programming (and gaming too). I appreciate any suggestions. Thanks

How can I run java program on these machines?

By following what the usage message tells you.
Bare minimum:java SomeClass (You don't actually type "SomeClass." That's just a generic placeholder for the name of the class whose main method you want to run.
More common: java -cp C:\some\path;C:\some\other\path\something.jar SomeClass something somethingElse And again, those are of course just generic placeholders for your real classpath, class, command line arguments.
Of course, to do this, you'll have to have a Java program to run. Do you have one that you want to run? Or are you going to start learning how to code in Java? To write the code, you don't use Java, you use your favorite text editor or an IDE. Then you use javac to compile it and java to run it.

Thanks for posting this!
I would only mention that your definition is incomplete for this -
Contextual selector A type of Style Sheet Selector that
and that it's most often referred to now as a Descendent selector, not a contextual selector. It's basically the same as the Compound selector that you have already defined....
