Thanks for the feedback. I'm having trouble getting my getText method to return the actual value, but here is my updated code:
BufferedReader br = new BufferedReader( new StringReader( getText() ) );....
public void getText(Document doc)

     NodeList nodeList = doc.getElementsByTagName("Interface");
     for (int i = 0; i < nodeList.getLength(); i++)

               NodeList ndLst = element1.getChildNodes();
               //System.out.print((ndLst.item(0)).getNodeValue());
     return doc;
}Here is the compiler error I am getting:
ImportDesc.java:32: error: method getText in class ImportDesc cannot be applied
to given types;
BufferedReader br = new BufferedReader( new StringReader

found: no arguments
reason: actual and formal argument lists differ in length
Note: ImportDesc.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
1 errorThoughts?

How to connect to Pgsql on server through jdbc with java on local machine

I am developing an application in which I have to connect to my database that is in Pgsql and Pgsql is installed on Linux server. I am going to access that from my java program and the java is here on my local computer(in Linux). All the intranet connections are there. How can I get accees to that database? I have heard of java SSL tunnel. Is this the only solution or there is something else that I can use more easily. Also if I use java installed on th same server as Pgsql then what I will have to do to call the java methods using AMI. Will the java at server be able to make connection to Pgsql more easily? Please tell me about it if you know.
Thanks

The closer java and pgsql, the easier it is of course to connect. So the easiest way is to have everything on the same machine. If you are in the same network you will need an IP based network, which is pretty much standard these days. In this case you need to modify the pg_hba.conf file to allow connections from other machines. In both cases you have to start the postmaster with the -i option to enable enable TCP/IP connections.
Having java and pgsql connected through the internet is a different story, I do not have any experience with that. But you can use ssh to build a tunnel and connect to a local ip address / port from java which is then forwared securely via the internet to the server.
In all cases you will need the postgres jdbc driver in your classpath. You can find information about postgres and jdbc on the postgres web site.
good luck

How can I find a printer that is compatible with my ox 10.4.11 operating system

Helllo,
I have several questions but my most current one is how can I find a printer that is compatible with my current operating system?

Brother is good about supporting older Mac OS versions. We have their HL5250DN b/w laser that supports all the post-1997 Macs in the house, including a 1998 vintage Beige G3 minitower running OS 10.3.9. There is also a driver with OS9 support on the Brother web site.
The bigger problem, based on posts I see in these forums, is not a printer failing to support an older OS but one not supporting a new Mac OS. There are numerous posts after a big OS version change (like the intro of Lion) where people run out and buy whatever printer looks cute/sounds good without researching whether the device supports the new OS yet. Printer makers are often not good about having updated drivers developed by the time Apple rolls out a new OS.

How can I develop co-broswing on Windows platform with java language?

How can I develop co-broswing on Windows platform with java language?
The function will be realized
Now I want to develop a co-broswing system with java language on Windows platform.That is to say I will develop
a application run on client to track the present browser.Wheh the URL address of your present if changed(for example
when you click a link or submit a form),the application will capture the new URL address and send it to the other
client that make co-browsing connect with you.The browser on the other client side will catch the new URL and refesh
the page to show the page.
The question I fall across and want to ask you
(1)How to watch system process with java on the Windows platform?Because I want to get the process information of
the present broswer,and then get the URL address of the present broswer.
(2)Develop an application to watch the URL address of the present broswer continuance,If the URL address is changed,
then send the new URL address to the client on the other side,let his broswer to show the new page using the new URL.

Paulc, A proxy server is not the right thing.
What our man here is looking for is a solution for two
users to kind of surf the net "in tandem" - when one
user navigates to a different web page, so does the
other user,
These are typically used in call center applications
where the advisor guides a caller through , say
filling in an insurance form or pointing him to the
right product specification pages.
Xing, why are you using Java for this ? You need
something that has better windows integration. If you
look on MSDN.microsoft.com and search for "explorer
bar" you will find solutions to the questions that you
raised.
There are also commercial products on the market that
already do this kind of stuff. there is one from
www.genesyslabs.com which is considered to be the best
of breed.
It is difficult or almost impossible to do this in
Java for a commercial application.
If you are developing this as an academic exercise,
give it a try. Post your email address here, and I
will contact and help you out if you like.my e-mail is below ,I want to contact you and need all of your help.

How to connect i phone printer

I CHANGED MY INTERNET PROVIDER BOX AND RE SET MY PRINTER TO WIRELESS SUCCESSFULLY...HOWEVER IMY I PHONE NO LONGER CAN FIND THE PRINTER??? NO PROBLEM BEFORE THIS...I COULD PRINT FROM MY PHONE WITH NO PROBLEM

Hi,
Are you using the airprint function of the iPhone or a print app like HP ePrint? It might be worth downloading the HP eprint app and trying to print using the app.
I know that you've laready tried this but restart the iPhone again to see if it re-establishes a connection. Once the phone and printer are on the same wifi network, you should be able to see the printer via airprint and any print apps.
Alternatively, you can use the wireless direct funtion of your printer by turining on the wireless button on the front of the printer. This allows the printer generate it's own wifi singal that you can connect to through any wireless device. To find the wireless password, simply hold down the wireless direct button for more than 3 secs and it will print the password on plain paper (make sure paper is loaded).

I'm sure someone can, but without more information, such as any clue about the type of printer/print server, or some idea about your network setup, this is the kind of task that is impossible to do blind.

How to connect WPS (BlackBerry phone) on wi-fi with airport express ?

If I were to connect the AirPort Extreme to my modem (DPC3825) via an Ethernet cable and then (wirelessly) connect my new iMac to the netowrk, would I receive 802.11ac or just b/g/n still?
802.11ac would be received by the iMac if it connected to the AirPort Extreme wireless signal....and....the iMac was in close proximity to the AirPort Extreme.
802.11ac uses the 5 GHz frequency, and these signals only work well then the router and computer are in the same room or have a line-of-sight relationship to each other, or very close to that ideal.
In addition, when I connect the AirPort Extreme to my modem, will it create two networks
The AirPort Extreme will create a network with two bands or frequencies.....one 2.4 GHz for "b", "g" and "n" wireless devices and another band, the 5 GHz signal for "n" and "ac" devices.
If you assign the same name to the AirPort Extreme network that you use for your existing network, and both routers are using the same wireless security settings and password, then everything will act like one "big" network.
If you assign a different name to the AirPort Extreme wireless network, then you will have two different networks....one produced by your existing router and the other produced by the AirPort Extreme.
If you move from one area to another, you will have to log off of one network and log back onto the other network.
