Can Java be used to link client/server?

Hello,
I do not know a great deal about either subject but I was wondering whether there was any information online (or indeed a product...) which is Java based to provide a link between a client/server environment. Specifically in this case online, i.e. an online catalogue where clients can interrogate (i.e. search for products etc.) a server.
Thank you for any help!
Tom.

an online catalogue where clients can interrogate
(i.e. search for products etc.) a server.The short answer to your question is: "Yes, Java can be used to develop the product you mentioned."
The longer question comes in how do you want the users to access the on-line catalogue?
It can be made as simple as a generic browser accessing your catalog which can be complete with pictures, descriptions, searches, and purchase information...
or any combination of complexity up to having to use a user developed applicatoin to hit your site. Java can be used to implement the entire range.

WLC CT2504: Interface IP can not be used as internal DHCP server IP

Hello all,
I've got a new CT2504 controller with software version 7.0.220.0
Regarding to

You can use the internal dhcp, but you need to set the primary dhcp as the management ip. So in your dynamic interface, your primary dhcp is configure with the wlc management ip address. Dhcp proxy also needs to be enabled and is enabled by default.

Can Java be used to manipulate the Windows registry?

Can Java be used to manipulate the Windows registry? If so, can someone point me to some examples?
Thanks!

There is no supplied capability to do this, because the registry is Windows platform specific.
It might be possible by making the call through a native Windoze app.

Why can I not use mobile link in reader on window Vista?

Hi sze wing,
Please tell us a bit more--what do you mean by "cannot use"? Do you get an error message? Or are files not syncing as you expect?
Have you double-checked to make sure that Mobile Link is on? Please see Acrobat Help | Mobile Link: open once, read anywhere for instructions on enabling Mobile Link, if it isn't already enabled.
If it is enabled, and things still aren't working as expected, please let us know what issue you're facing, including any error messages.

XDK APIs (C/C++/Java) and tools can also be used with MS SQL Server

I want to know if XDK APIs (Java or C/C++ APIs especially) and tools can be used with MS SQL Server or not?
I want to write a simple application that updates XML ( acordXML used for insurance) document into SQL Server tables. Of course I am assuming to transform into appropriate XSU APIs format.

No. Use SQLXML instead on a SQL Server.

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 to set up new MBP to use D-Link print server

New to Mac. MBP found 2 of my 3 printers right away. Tried manually configuring the 3rd which is an older HP Laserjet 1320 connected via USB to a D-Link print server. In Win you config using the IP address and port name. Configuration appeared to work but nothing gets sent to printer. If this is an easy fix I would like to go that route but if the print server hardware is too old please suggest good alternative that will work for both Windows and Mac systems as I have both in the house.
Thanks

I was able to resolve this by rebooting the print server.

Can Java be used to save content of HTML form to a file?

We have an application that saves a pdf file to a location on our webserver. The file displays on the users machine in a browser window. I have created a link in the links bar of the browser window which launches a simple HTML page. This page allows the user to enter a number of fields and click 'SAVE'. This is where I am having the problem. I need the save button to firstly create a csv file on the webserver containing the details input by the user. I then need the pdf file saved to the web server with a new name and in the same location as the csv file. is there anyway to achieve this using Java or can anyone please point me in the right direction?
Thanks

<<Click on the SAVE button in an HTML <form> and the browser will perform an HTTP POST of the data to a URL. Make that URL point to a Java servlet and it can take that form data
<<and write it to the webserver file system in any format you wish, including csv and pdf.
agree with duffy. You can also use JSP and call a class method to handle whatever data you specify.

How to compile and run a Java servlet using the BEA weblogic server

          Hi,
          Could you help me out as to how to compile a servlet using Web Logic server.I have written a Servlet program and have also set up the environment in the "c:\bea\wlserver6.0\config\examples" folder by giving the command setExamplesEnv.cmd.
          I have stored my GreetingServlet.java file in "c:\bea\wlserver6.0\samples\examples\servlets" folder.
          How do I compile my servlet now?
          Vid


Hello,
1. The .form file was used by Netbean's GUI builder to create the .java and is not needed for compilation.
2..../src # javac -classpath "..." mytool/*.java
I guess the package mytool was not coped with.
Alternatively it is worth to use the ant build tool also used by Netbeans.
Then you can make a jar from the class files, indicate in the manifest.mf file:
1. the main class
2. the library jars

Can Java be used to write service/daemon at solaris?

I new to solaris server side developement, thinking not go back to c/c++ on solaris, to write the system service or daemon. Can I use java to achieve this instead of c/c++ ? Or where I can find the samples / resources about this?
Thanks,
Ben

There is no reason you cannot write a daemon in Java. The cloudscape database daemon that was shipped with the original Forte for Java is written in Java. You need to decide if Java can give the the performance you require for your service/daemon, however.
You can find some examples and an API for writing Java Daemons at:
http://www.jcp.org/en/jsr/detail?id=96
http://jakarta.apache.org/commons/sandbox/daemon/

Can Java be used to parse Microsoft Word(.doc) files?

Hi guys ,
I want to know whether Java can be used to parse Microsoft Word(.doc) files for searching a string or for checking for grammatical errors, etc
Thanks in advance.
Avichal

Hey man, anything and every thing can be done these days.
About ur question doc is like all other normal text files with some extra features and extra character supports and other stuffs.
If u neglect those parts and if u consider it to be a normal text file then its a much simpler job.
Here is a code that searches for the key word in all the doc files, txt files, pdf files and html files
in the mentioned folder and sub folders. Any way its a servlet u can change it to a normal program.
It first check the file to know whether they are doc, pdf, html or txt files if yes then it will read the file and
store the contents in the vector and parse the vector for the search string and display the result.
Along with the result the below code will also display the time taken and the number of search string found in the document

Why can't I use default email client?

PSE 12, Windows 8.1. It would be awesome to be able to just have a SEND TO Email client from within the program, but forcing us to use Microsoft's horrible email program is not satisfactory. I'm sure I'll just have to end up doing it the hard way, saving the file, open a new email client message, attach the photo and SEND, but it shouldn't be necessary. I always use Thunderbird for all my email and don't wish to change. I never could get Microsofts Email to work with all my email programs.
Why wouldn't Adobe configure such an important and often used option for the user to use?
Thanks
Tim

Just discovered that Photoshop Elements 12 will not work with my Facebook either... says there is no internet connection, which there is. Disabled Anti-Virus, no firewall, everything else working fine. I guess I'll stick to what I know PSE can do.

Can java be used for game dev?

(Side note)-when I first posted here a couple months ago I decided to stop because of final exams.
I want to get back into programming again and Im thinking about starting into java (again). My future hope is to eventually make a basic game. Can you do that with java because a lot of people tell me java 3d is a horrible and useless system.
thanks

If you're working on this project by yourself, I wouldn't recommend using Java 3D. It takes a lot of effort to get even simple 3D graphics working the way you want them to in Java 3D, and the learning curve is pretty steep. I don't have any experience with jogl, though, so I can't say whether or not its any better.

I can no longer use hot links in e-mail (Yahoo Mail). What is going on?

I noticed recently that all hot links in my Yahoo E-mail messages are dead. I don't know if this is occurring on the recipient's end. I hope not as this would be rather embarrassing.
I've tried several tests where I embed links in text to both websites and downloads from my Dropbox. All dead.

Hi, I know, I've heard from other PPC users. The latest Flash Player would be version 10.1.102.64. So Google Maps won't support that version either? That version didn't come out until November 2010, less than 4 months ago!!
So Google Maps won't support Flash Player version 10.1.102.64? a 4 mo old version? Wow, that's a short "shelf" life!!
What about Safari? I don't use a Mac, so don't really know.
