Java and Networks - questions

Hi,
I have this idea in my head, and i wanna get it out..
Okie the plan is that I want to create something like a macro program. The special thing is that I want to create a server and 2 clients. The thing I want is that whenever I hit a special key from Client1, that key is going to be sent to the server,then the server is going to modify it, and then send to the Client2. And then the Client2 will invoke the key just like a macro program.
Okie the networking part, I kindda have an idea what how to do it. However since it is more like a macro program, I want it (client/server) to run simutaniously with other programs I am running.
Ex:
Let's say I am playing a game, I hit number 1 to signal the game that I want my unit to attack something. Meanwhile the Client gotta capture the key 1 that I just hit and send it to the server and then the client2, and then perform an action of pressing a key that a server sends to.
Could anyone have an idea of how to do the capture keys and invoke keys as I mentioned above?
Thank you
please email me at [email protected] if you could help me out

JNI (Java Native Interface) is the interface between Java and C (usually native functions in C). In C you can do a lot more low-level stuff than in Java, particularly interacting with the OS at a system level. This is the native part.
Ie, the system knows about all key events. It then sends them to the OS, that only directs them to the program with focus. (Might be java, might not. But no program can get keyevents intended for another program).
Using JNI, you could intercept the keyevents betweent the system and the os, and do what you want with them.
But, I don't know JNI, and I don't know much about it. This is mainly guesswork. It's along the right track, but the system/os stuff might not be 100% correct.
The other thing is, once you start writing code that interacts directly with the system, it loses all cross-platform compatibility. IE, if you write something that interacts with windows, it obviously won't work on Linux.

System control with java, and networking in jave

Hi, just a couple of questions.
Ill start witht the networking query. Ive been making a basic network chat program using sockets. The text is transfered through the sockets as strings read in from text field on the interface
eg
kkSocket = new Socket("xxx.xxx.xxx.xxx", 80);
out = new PrintWriter(kkSocket.getOutputStream(), true);
in = new BufferedReader(new InputStreamReader(kkSocket.getInputStream()));
String fromUser = (ba.text());
out.println(fromUser);
All this works fine, i want to impliment file transfer into the app, but im clueless how to transfer anything other than a basic string over a socket, let alone send it to a specific location on the client computer. Any help / advice would be well recieved.
Also, as i have basic code, that can connect computers, and send messages between them, i was wondering how i control some of the system functions, like executing files, opening / closing cd tray etc through java. As with this, i could create a mini remote control application.
Again, any help on this (or even a pointer to relavent things in the java api) would be fantastic as the more i can understand the more inventive i can be when coding

You seem to manage well even though you're posting to New To Java Technology, I've seen far worse questions in ALT even...
All this works fine, i want to impliment file transfer into the app, but im clueless how to transfer anything other than a basic string over a socket, let alone send it to a specific location on the client computer.To send files/binary data, you would use a BufferedInputStream (remember Streams are for binary data, Readers/Writers are for text) in a similar way you're using PrintWriter and BufferedReader now.
It could go a bit like this (invent your own protocol):
User1 sends a String that says: FILE C:\directory\file
User2 receives the String and prepares to save a file to the specified directory.
User1 sends the binary data to User2.
User2 reads the binary data and writes it in the file.
Controlling system functions in Java can be tricky, so you might not get all the functionality in your program that you want. Running programs can be done through System.exec(), but the CD tray might be impossible even.

Java and networking; best method?

I am writing a manufacturing application where the DB will reside on a server. I need multiple computers utilizing the application concurrently.
Is there any reason why each workstation couldn't have a copy of the application and simply point to, and access, the DB on the server?
Or should the application also reside on the server with client applications on the workstations?
I am concerned that the latter may be best but more programming.
Looking for advice and opinions.
TIA

Java and sql question

is ther a way to index in an atumatic way the rows of a database table?
for example if i delete the row numer 4, there will be no more index 4. So i need that when i delete a row the hole table indexes again the rows in order to not lose the index number of the row it has benn deleted.
am i clear enough, excuse my englis thanks

Perhaps you should say what you are trying to do and why to make it clearer.
Recalculating an index for every record in the database every time sounds quite hard on the processor.
My database automatically gives a unique number called an oid to every record, which I often find useful.

Java and encryption - question please...

Hi all,
Does Java provides libraries for encryptions eg DES. or i need to find Dll or alternatively write the whole crap?
any hint, online tips , example will be appreciated.
best regards
rahman

Thanks for quick replies of you guys!!
I really really appreciated.
Mine is jdk 1.4 which means i already have the encryption stuff.
Is there any example available to show usage of one of these encryptions eg DES at all.
will be really appreciated.
regards
rahman

Anyone know of a report on the suitability of java for network games?

Sorry for the long title but couldn't think how to shorten it without losing my point...
I'm currently needing to write an appriasal for uni and i need some research material that'll help with this subject.
Though I can find stuff about java and networks and delays there's nothing about games. Any help would be greatly appreciated :)

I don't know of any specific reports on this, but if you analyse the differences between other areas of networking and game-specific network code and then research whether or not java handles these elements well you should be able to put your own one together fairly easily. Then just post it online and you will suddenly be an authority in the field :)

Sample JAVA Mobile Server Publish code, and technical questions

Dear Oracle technical representative, or user:
I need to programmatically create, and remove publications using the pure JAVA classes of Consolidator, ConsolidatorManager, and ResourceManager for the Mobile Server in OracleLite 9i Release 5.0.1. On the creation side I have managed to get the example found in the directory OraLite501\Mobile\Server\Sample\Sample11 functioning using my installation parameters. I had a very difficult time of it because (1) the sample11 code fails to open an jdbc connection to the Mobile Server Repository Schema with the function Consolidator.OpenConnection, and (2) the ResourceManager function openConnection will not work unless the Webtogo.ora file is in the current working directory. The ConsolidatorManager function OpenConnection may also not work unless the Webtogo.ora file is in the current working directory, but I did test the hypothesis. Both of these problems need to be addressed in the sample11 code, and documentation to save other software developers from wasting hours of their valuable time. See line 223, 386, and 448 in the Publish.Java code that follows this problem description.
With the above two problems resolved, I can now programmatically create publications, but no hints on how to programmatically remove a publication exist in the documentation. The application I am developing will require the dynamic creation, and removal of publications. Also, when developing applications the complete removal of a publication is absolutely necessary when you have botched a publication. Thus my first question is What sequence of ResourceManager, and ConsolidatorManager function calls will completely remove a Publication?.
I also have two issues remaining with the code that I have so far developed. These issues will most likely be resolved, when I obtain instructions on how to completely remove a publication, and associated users. But, perhaps not. Referencing the Publish.java file that follows this problem description,
     1. The ResourceManager function dropUser does not drop a user. See my comments, and code beginning at line 277 in Publish.java. Do I need to de-instantiate all subscriptions, and unsubscribe all subscription users before calling this function.? I think, I tried the de-instantiate, unsubscribe sequence without success, but in the confusion I may not have made the try.
     2. How do I get rid of an index created with the ConsolidatorManager function DropPublicationItemIndex?. My comments on this problem begin at line 522 in Publish.java. For some reason the DropPublicationItemIndex function call made below line 448 does not work. What function calls are required prior to calling the DropPublicationItemIndex function?
Throughout the Publish.java code, I have made comments about some of the problems that I have had in getting the sample11 code working for my installation parameters. I think these comments should help the programmers maintaining the ResourceManager, and ConsolidatorManager code improve the stability of the programs. Please pass these comments, and attached files to the appropriate individuals,
if you are in a position to do so.
The other files that follow the Publish.java code are
     1. Compile.bat - Compiles Publish.java using j2sdk1.4.0.
     2. Run.bat - Executes Publish using \ j2sdk1.4.0\jre\server\jvm.dll.
     3. Webtogo.ora
     4. tnsnames.ora for the Mobile Server.
     5. tnsnames.ora for the Database.
Feel free to access my server if you need to do so in resolving my problems. The parameters you will need to gain access can be found at the top of Publish.java, and in the included *.ora files.

Dear Oracle technical representative, or user:
I need to programmatically create, and remove publications using the pure JAVA classes of Consolidator, ConsolidatorManager, and ResourceManager for the Mobile Server in OracleLite 9i Release 5.0.1. On the creation side I have managed to get the example found in the directory OraLite501\Mobile\Server\Sample\Sample11 functioning using my installation parameters. I had a very difficult time of it because (1) the sample11 code fails to open an jdbc connection to the Mobile Server Repository Schema with the function Consolidator.OpenConnection, and (2) the ResourceManager function openConnection will not work unless the Webtogo.ora file is in the current working directory. The ConsolidatorManager function OpenConnection may also not work unless the Webtogo.ora file is in the current working directory, but I did test the hypothesis. Both of these problems need to be addressed in the sample11 code, and documentation to save other software developers from wasting hours of their valuable time. See line 223, 386, and 448 in the Publish.Java code that follows this problem description.
With the above two problems resolved, I can now programmatically create publications, but no hints on how to programmatically remove a publication exist in the documentation. The application I am developing will require the dynamic creation, and removal of publications. Also, when developing applications the complete removal of a publication is absolutely necessary when you have botched a publication. Thus my first question is What sequence of ResourceManager, and ConsolidatorManager function calls will completely remove a Publication?.
I also have two issues remaining with the code that I have so far developed. These issues will most likely be resolved, when I obtain instructions on how to completely remove a publication, and associated users. But, perhaps not. Referencing the Publish.java file that follows this problem description,
     1. The ResourceManager function dropUser does not drop a user. See my comments, and code beginning at line 277 in Publish.java. Do I need to de-instantiate all subscriptions, and unsubscribe all subscription users before calling this function.? I think, I tried the de-instantiate, unsubscribe sequence without success, but in the confusion I may not have made the try.
     2. How do I get rid of an index created with the ConsolidatorManager function DropPublicationItemIndex?. My comments on this problem begin at line 522 in Publish.java. For some reason the DropPublicationItemIndex function call made below line 448 does not work. What function calls are required prior to calling the DropPublicationItemIndex function?
Throughout the Publish.java code, I have made comments about some of the problems that I have had in getting the sample11 code working for my installation parameters. I think these comments should help the programmers maintaining the ResourceManager, and ConsolidatorManager code improve the stability of the programs. Please pass these comments, and attached files to the appropriate individuals,
if you are in a position to do so.
The other files that follow the Publish.java code are
     1. Compile.bat - Compiles Publish.java using j2sdk1.4.0.
     2. Run.bat - Executes Publish using \ j2sdk1.4.0\jre\server\jvm.dll.
     3. Webtogo.ora
     4. tnsnames.ora for the Mobile Server.
     5. tnsnames.ora for the Database.
Feel free to access my server if you need to do so in resolving my problems. The parameters you will need to gain access can be found at the top of Publish.java, and in the included *.ora files.
Thanks,
Thomas G. Matney

I have a Photosmart C7280 and have question s about making a network decision.

I currently have two desktops connected to a wireless router via ethernet cables. They are connected to a single (non-HP) printer with USB cables through a USB switch. Two laptops connect to the router wirelessly. I could replicate the existing configuration with the C7280, but the idea of a network in which the laptops could participate is very appealing. One of the laptops is running Windows version 7, the other computers are running Linux. If I go for an ethernet network, will the laptops be able to connect to the printer through the router? If I go for a wireless network, will the desktops be able to connect to the printer through their ethernet cables? A couple of USB wirelss adapters are a possibility.
This question was solved.
View Solution.

I understand that you have some questions regarding networking with your printer.
Yes, wired network connections will have no problem connecting to a wifi connected printer. Most routers bridge wired and wireless networks to work as a single network. There are a few routers that separate wired and wireless networks, but these are primarily enterprise grade routers and networking equipment.
A wired desktop will be able to print to a wireless printer as long as it is connected through the same router. Vice versa, a wireless computer can print to an Ethernet connected printer as long as it is the same router.
I recommend using a network setup for the printer, if possible, to avoid printing issues. USB hubs have been known to cause some printing problems, though this is not always the case.

Im new to java and hope somebody can help me with my question

Hi!
Im quite new to java and I just have some simple questions..
can someone please tell what kinds of error are considered as language violation for java? where can I find more info about these errors?
can someone give me a simple example on a kind of error that cannot be caught in both compilation and runtime? I hope someone can help me out. Thanks in advance!!

Im just asking about errors that might go against the language definition but cant be detected.. If it "goes against the language defintion," it will be detected by the compiler. That's half of the compiler's job is to tell you what you've done that violates the language spec.
because it confuses me when they say that such errors might occur so I just want to know what might these errors be.. sorry for that..Who's "they"? What exactly* did "they" say about "such errors"? It sounds to me like you're just confused, and you think there's something mysterious and inexplicable going on but you don't know what and don't even know what you're asking.
I would suggest not worrying about hypothetical problems that you can't even put into words and focussing on learning Java. Along the way, if you encounter real, specific, actual problems, ask about them, and you'll probably get answers about the problems themselves and the language or theory behind them.

Java Script and JSF question

Hello,
I have a JSF component like this that has a pageSize attribute. It shows a grid with 5 elements.
<x:gridView id="#{tab}GridView" pageSize="5">
</f:gridView>Then I have a drop down with 5 menu items where the user can select how many elements they want to see visible on the grid. My question is, how do i use Java Script to to change the pageSize attribute above with what the user selected in the menu below? I have been looking at java script code and online docs for an hour and cant come up with anything that seems to work. Any help will be appriciated. Thank you!!!
<x:selectOneMenu id="myMenu" onclick="">
<f:selectItem id="perPage1" itemValue="1" itemLabel="1" />
<f:selectItem id="perPage2" itemValue="2" itemLabel="2" />
<f:selectItem id="perPage3" itemValue="3" itemLabel="3" />
<f:selectItem id="perPage4" itemValue="4" itemLabel="4" />
<f:selectItem id="perPage5" itemValue="5" itemLabel="5" />
</x:selectOneMenu>

[...]how it was never designed to be used for
such large applications[...]All I can say is that if this is true, then it doesn't show. Yes, I know it (oak) was originally designed for embedded systems, but Java and Oak aren't identical.
My assembly teacher
always makes fun of Java, saying java gives you far
less control, it prevents you from making mistakes.
No control over unsigned/ signed values, pointers
etc. Yes. But broadly speaking that's the point. Java sacrifices control over such things. The return, however, is that programmers are able to be more productive because of the great swathes of problems that can no longer arise.
The mistake is in assuming that Java is the best tool for everything. It isn't, and in fact no language us. As it turns out, Java is just great for building enterprise systems. It has a few other strengths, some of which (applets for example) have been more important in its original uptake but are now relatively minor features.
You don't write an enterprise website in Intel assembly, and you don't write device drivers in Java.
Not saying its not good but its good for
smaller applications like cell phones and
mini-computers.I think you mean something different by mini-computers to what I mean...
Its portability is actually the main point in its favour for use in cell phones. If it weren't for that, I think C or C++ would probably have sole ownership of that space.
Now i'm not saying any thing against it just
confused on why a class like data-structures at my
University [...] would be taught using java when C would
probably be a lot better for Very Large ADTS.You and Joel Spolsky:
http://www.joelonsoftware.com/articles/ThePerilsofJavaSchools.html
I disagree, because I don't think it much matters what language you learn - experience trumps any particular initial language choice. If you're still using Java in 15 years I'll be fairly surprised.

Question about java and batik

i want to make a project using batik.. if i want to animate the svg, can batik do this? i am confused about batik. does it support animation? and how do i read the mouse coordinates in an svg using batik? please help..

thanks for the reply! what i mean in the second question is does the canvas in batik support mouse coordinates?
from what i understand is i can add interactivity to a svg by using batik and java and no javascript.. am i right? i am asking because i am doing a gis project and i want to do it in batik and java. after creating the svg file in the web, it will be downloaded from a phone fow viewing. in orer to do that i have to do a program for the phone, right?

Three questions about Java and Ftp

Hello, i've the following questions about Java and Ftp:
1- .netrc file is in $HOME directory but i can't access to this directory from java code. The following line producesan Exception (directory doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");
2- .netrc file must have the following permissions: -rw- --- --- but when i create the .netrc file the following permissions are on default: -rw- r-- r--, how can i change this permissions? (In java code, i can't use chmod.....)
3- Are there any way to pass parameters to a .netrc file? If i get to do this i needn't change the permissions because i can't modify or create/destroy this file.
Thanks in advanced!!!
Kike

1- .netrc file is in $HOME directory but i can't
access to this directory from java code. The
following line producesan Exception (directory
doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");$HOME would have to be replaced by a shell, I don't
think you can use it as part of a legal path.
Instead, use System.getProperty("user.home");
Ok, thanks
2- .netrc file must have the followingpermissions:
-rw- --- --- but when i create the .netrc file the
following permissions are on default: -rw- r--r--,
how can i change this permissions? (In java code,i
can't use chmod.....)Yes, you can: Runtime.exec("chmod ...");
I need to use estrictly the .netrc with -rw- --- --- permissions
Yes, i can use Runtime.exec ("chmod ..."); but i don't like very much this solution because is a slow solution, am i right?
3- Are there any way to pass parameters to a.netrc
file? If i get to do this i needn't change the
permissions because i can't modify orcreate/destroy
this file.I don't think so. Why do you need the .netrc file in
Java at all? Writing a GUI frontend?I want to use automatic ftp in a java program and FTP server, the files and path are not always the same, so i can:
- modify .netrc (for me is the complex option)
- destroy and create a new .netrc (is easier but i have permissions problem)
- use .netrc with parameters but i haven't found any help about it
Thanks for your prompt reply!!!!

Few question about Java and MySQL connection

Hi!
I have some problems with creating connection between Java and MySQL.
I followed the restrictions in mysql-connector-java.jar' readme, I set the CLASSPATH :
CLASSPATH=.;D:/mysql/mysql-connector-java.jar;
I copied this jar file to the right place (descripted above), and I used the right steps to load it:
Class.forName('com.mysql.jdbc.Driver"); and it throws a ClassNotFoundException
Why? All the paths are correct, everything is on the right place.... I dont know why.
When I installed the JBuilder8, and copied the jar file to JBuilder8/jdk4/jre/lib/ext it worked without any CLASSPATH in enviromental variables.
If I want to run my program on machines where are not JBuilder, what should I do?
Please help, if you can.
Thanks,
henpanta

Yeah. So if I compiled my program with JBuilder to an .exe file, I cant run it on other machines, if the jar file isnt in the same place?
If I tried your advice, java -classpath mymainclass I got the next message:
main class not found. Believe me, its there. :(

New to Java and stuck on alert ticker issue

Hi, I'm a newbee so go easy on me. Here's the issue. The company I am interning for monitors its networks using a console called WhatsUp Gold. The program creates alerts to inform of any issues on the network or when thresholds are close to being reached. This is done using some form of Java which I can view by opening the source files. They have asked me to try and create a scrolling ticker that automatically updates in real time along with the WhatsUp program. I have downloaded INSCRO (a ticker creator) but when I try to direct the feed to the URL on WhatsUp, the ticker scrolls the Java script and not the text that I need it to. Any ideas on how to get it to pull the text vs the source file?
Thanks in advance!

First, you need to get straight the difference between Java and JavaScript. They're related only by having similar names. If you're doing "View Source" in a web browser, what you're seeing is JavaScript, NOT Java. If this is where your question lies, you need to find a JavaScript forum.
