Problem with client side printing, please help its urgent
hi ,
am using struts and jasper reports on my project, now i was having problem that whenever i try to print the report , the printer dialogue box was appearing on server machine, i want it on client end, how to solve this problem, please any one know help me, it was urgent,
my code was like this
JasperCompileManager.compileReportToFile("c:/report/test.jrxml","c:/report/test.jasper");
JasperPrint jasperPrint = JasperFillManager.fillReport("c:/report/test.jasper"),parameters,con);
List l=jasperPrint.getPages();
if(l.size() != 0){
jasperPrint.setOrientation(JasperReport.ORIENTATION_PORTRAIT);
jasperPrint.setPageHeight(877);
jasperPrint.setPageWidth(963);
JasperPrintManager.printPages(jasperPrint,0,l.size()-1,true);
}thanks in advance,

Problem with Accessing Deployed Servlets Please help, very urgent.
Inspite of going through lots of Docs. I am not able to access the JSP which is deployed using JDeveloper 3.2 in the browser? What should be the URL and where should I place the JSP and the related files in the Apache Server (Specific directory)?
Please help, this is very Urgent.
Could I get some sites where I can get detailed description of how to deploy and access Servlets and JSPS using JDeveloper 3.2 for OAS 9i?
Thanks in advance,
Regards,
Kavita.
nullHi Kativa,
In answer to your first question: In most apache installs, you want to place all your JSPs under the Apache/htdocs directory. This htdocs directory becomes the root directory of your HTTP request, so, for example, to access the file
Apache/htdocs/mydir/myJSP.jsp
you'd point your browser to
server:port/mydir/myJSP.jsp]http://server:port/mydir/myJSP.jsp
As to your second question: Do you mean Oracle 9iAS? If so, look at this HOWTO: http://technet.oracle.com:89/ubb/Forum2/HTML/006398.html
JDeveloper 3.2 does not support deployment to OAS (the predecessor to iAS), but there was no OAS 9i.

}thanks in advance,Throw away the code that generates a JasperPrint object and tries to print it. (All of the code, in other words, except maybe the first line.) As you found, that tries to print on the machine where the code is running. Replace it by Jasper code that produces PDF or HTML, and send that as the response. Let the person sitting at the browser deal with printing it if they want.

Having problem with client side Authentication.
Hi,
I am haveing a problem enabling client side authentication with SSL on
weblogic 5.1.
I have set up the .properties files as explained, however it appears
my client is not sending a certificate back to the server. The same
client however works perfectly (using the same keystore file) with a
sample ClassFileSErver webserver from the jsse distribution. (the
client is a very slightly modified version of
SSLSocketClientWithClientAuth sample that comes with Jsse)
Below I've included a section of the debug dump from the interactions.
The only other difference I can see is the cipher suites offered by
the servers.
Weblogic offers type 0 or 9, and agrees on type 9
(SSL_RSA_WITH_DES_CBC_SHA), whereas ClassFileServer offer type 0 or 5
and settles on type 5 (SSL_RSA_WITH_RC4_128_SHA).
I am using the same keystore for both examples. Both servers request
an RSA client cert.... I'm out of ideas.
Any help would be greatfully received.
Cheers,
Keith

*** Certificate chainMatt,
Did you read this article:
https://wiki.sdn.sap.com/wiki/display/BSP/Using%20Proxies
This explains how to properly setup the HTTPURLLOC table.
In your case you should have entries that look something like this:
40 HTTP * <internal host name> <https port>
50 HTTPS * <external host name> <https port>
In addition you need to run the report to determine if the proxy configuration is setup properly. The URL should be run with the
https://<externalhostname>/sap/bc/bsp/sap/system_test/test_proxy.htm
Take care,

Problem with touch screen. Please help!!!
Ok I bought an iPad about a month ago now. At first it worked perfectly, runs apps smoothly, etc. But then something happened to the touch screen, it just randomly like pressed itself, it went into apps on its own and zoom in and out while on safari just randomly. For about 3 weeks this issue disappeared, but now it happens again but more constantly and for more time please help. I think this video will explain my issue more clearly. http://www.youtube.com/watch?v=e1qyvHV43yg Please I just don't want this issue anymore. Any help will be appreciated.
OK...so it seems that many iPad owners have the same issue with the screen "self registering touches". You'll see multiple posts on the forums from "self touching" to "self registering" to "freaking out".
Well, I also have this annoying problem.
Trust me when I say that cleaning the screen, resets, charging, deleting apps, static, and so on haven't anything to do with causing or resolving this issue.
Here is a little tip to show you what is actually going on. Download a free app that shows you "screen touches". Harbor Master is one that I've heard of that led me to this...but I prefer to use that pocket pond app...only because I can just sit back and watch without having to move boats around.
...When you notice the problem, open up the app. I've noticed on mine that it only self registers touches along the side. Exact location is (when holding iPad in landscape position, home button on left) along the top of the screen...from top middle to the top right corner.
I have called Apple...the tech was polite and tried to help. ...But the only suggestions were to reset (as i've already done) then if that didn't work I was to do a reload while sync'd. He stated that if none of that worked then to take it to the store...
Since I am in Florida for the month and the nearest Apple store is 6hrs away...I will wait until I go back home HI and visit a store that is close by. -
Problems with the Proxy Programme--Please help
Hi All,
I have written a simple proxy server in the form of a servlet. I changed the proxy config of my browser to connect to this servlet hosted on the default context(http://localhost:8080) of the Tomcat 5.0.25 . Well , this servlet internally connects to the proxy of the corporate LAN . The logic that I have applied is as follows. The servlet gets the request from the client (ie the browser in this case) , extracts the headers and contents from the request, sets them to a new request that it forms and finally send this new request to the proxy. When the proxy responds, the servlet collects the response headers and contents adn writes them in its response. To sum up , this servlet transparently carries the requests and responses between the client(browser) and the corporate LAN proxy. Now the problem is this. Let's say , now I am accessing http://www.google.com.The browser sends a request to my servlet with the following headers as they are extracted by my servlet.
ProxyServer:::>posting request
ProxyServer:::>headerValue::> headerName = accept : headerValue=*/*
ProxyServer:::>headerValue::> headerName = referer : headerValue=http://www.google.com/
ProxyServer:::>headerValue::> headerName = accept-language : headerValue=en-us
ProxyServer:::>headerValue::> headerName = proxy-connection : headerValue=Keep-Alive
ProxyServer:::>headerValue::> headerName = user-agent : headerValue=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; UB1.4_IE6.0_SP1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)
ProxyServer:::>headerValue::> headerName = host : headerValue=www.google.com
ProxyServer:::>headerValue::> headerName = cookie : headerValue=PREF=ID=1be27c0a74f198ca:TM=1082058853:LM=1082058853:S=bu6ORrygzm8AUkm8
ProxyServer:::>postRequest
I set these headers into a new connection opened to the proxy and post a fresh request to the proxy,which, in turn responds with the following headers.
ProxyServer:::>posted request successfully
ProxyServer:::>writing response
ProxyServer:::>writeResponse-->headerName = Proxy-Connection : headerValue = [close]
ProxyServer:::>writeResponse-->headerName = Content-Length : headerValue = [257]
ProxyServer:::>writeResponse-->headerName = Date : headerValue = [Tue, 13 Jul 2004 14:01:40 GMT]
ProxyServer:::>writeResponse-->headerName = Content-Type : headerValue = [text/html]
ProxyServer:::>writeResponse-->headerName = Server : headerValue = [NetCache appliance (NetApp/5.5R2)]
ProxyServer:::>writeResponse-->headerName = Proxy-Authenticate : headerValue = [Basic realm="Charlotte - napxyclt2"]
ProxyServer:::>writeResponse-->headerName = null : headerValue = [HTTP/1.1 407 Proxy Authentication Required]
ProxyServer:::>writeResponse exiting
ProxyServer:::>wrote response successfully
I write these headers back to the client. According to what I was thinking, the client ie the browser would open a new dialog box asking for username/password owing to the presence of the "Proxy-Authenticate " header. But it does not happen that way. Rather the browser stops responsding and displays a blank page. Does anyone know why it happens this way? I am pasting the server prog below for everybody's reference.

Thanks for your reply. Well , I initially I thought of not pasting the code,as it was too long. But I could not help it,as I thought I must show in code what I exactly meant. That's why I followed a description of my problem with the code. You could probably have copied the code and pasted it in one of your favourite editors to take a look at it. Did you,by any chance, try to read it on the browser? And as regards reposting the same message, I can say that I did it as I felt the subject was not quite appropriate in the first posting and I was not sure as to how I could delete/alter the posting. I am not asking for a code-fix,but some suggestions from some one who might ever have come across such a thing.Anyway, lemme know if you have any idea on it. Thanks... -
HP Laserjet 1020 problem with double-side printing
Hi, everyone!
I have a problem with my printer HP laserjet 1020. From the community I know that there is no driver for 1020, but there is for 1022 (http://support.apple.com/kb/DL907). I installed it and everything was fine until I tried to print 2-sided page... It appears 2-sided option disappeared and I don't know how to fix this...
Can anyone help, please?
Thank you for looking.AMW122,
The part in the photograph appears to be part of the fuser assembly. If it is part of the fuser assembly, I would recommend you replace the fuser. An internet search on "LaserJet 3300 fuser" found several links.
From what I can see, it appears that the fuser sleeve is damaged which will continue to worsen.
If it is not the fuser, can you post another photograph further away so that we can see the location on the printer where it is located, etc...

Problem with adobe acrobat/reader - please help!
Hello,
My acrobat reader was fine and I was able to open the pdf files sent to me, then suddenly it just wouldn't open anything at all. It went into open mode and just stayed there, and wouldn't let me close it. Then I got a message saying "there is a problem with adobe acrobat/reader. Please exit and try again". I've done this lots of times and it still isn't working.
I would be very grateful for any help or suggestions. I have windows 7, and as I said its all been fine up until now.
Thanks.
mspryce.This is the Acrobat forum, not the Reader forum. You should check the reader forum. In the meantime, if you are not running AR9.3 or so, you should update. Prior versions before 9 are not designed for Win7 and that might be your issue -- you gave no indication of version.

this code capture every frame from movie but it never ends running and i can't invoke any metod after grabing frames becouse its still running. How Can I stop this to enter the next metod.
Please help me
thxAnswering sam04 question Yes this make that every frame is captured
Back to my problem :
I invoke caputre frames class from other class like this:
Film2ramki f2r=new Film2ramki();
f2r.startnow(pathtomov);
System.out.println("End of capture");...........................
So when capturing frames ends it should print "End of caputre" but I get something like this :
JPEG, 320x240, FrameRate=13.0, Length=18198
Video format: JPEG, 320x240, FrameRate=13.0, Length=18198
Pre: frame #: 1, time: 0.0, len: 16282
Post: frame #: 1, time: 0.0, len: 230400
End of capture
Pre: frame #: 2, time: 0.07, len: 16471
Post: frame #: 2, time: 0.07, len: 230400
Pre: frame #: 3, time: 0.15, len: 16620
Post: frame #: 3, time: 0.15, len: 230400
Pre: frame #: 4, time: 0.23, len: 16541
Post: frame #: 4, time: 0.23, len: 230400
Pre: frame #: 5, time: 0.3, len: 16749
Pre: frame #: 18, time: 1.3, len: 15708
Post: frame #: 18, time: 1.3, len: 230400
Pre: frame #: 18, time: 1.3, len: 0
Post: frame #: 18, time: 1.3, len: 0this is strange becouse it captures 1 frame end print "End of capture" and then its capures other frames. Why ????? -
Problem with simple drawing program - please help!
Hi,
I've only just started using Java and would appreciate some help with a drawing tool application I'm currently trying to write.
The problem is that when the user clicks on a button at the bottom of the frame, they are then supposed to be able to produce a square or circle by simply clicking on the canvas.
Unfortunately, this is not currently happening.
Please help!
The code for both classes is as follows:
1. DrawToolFrame Class:
import java.awt.*;
import java.awt.event.*;
public class DrawToolFrame extends Frame
implements WindowListener
DrawToolCanvas myCanvas;
public DrawToolFrame()
setTitle("Draw Tool Frame");
addWindowListener(this);
Button square, circle;
Panel myPanel = new Panel();
square = new Button("square"); square.setActionCommand("square");
circle = new Button("circle"); circle.setActionCommand("circle");
myPanel.add(square); myPanel.add(circle);
add("South", myPanel);
DrawToolCanvas myCanvas = new DrawToolCanvas();
add("Center", myCanvas);
square.addMouseListener(myCanvas);
circle.addMouseListener(myCanvas);
public void windowClosing(WindowEvent event) { System.exit(0); }
public void windowOpened(WindowEvent event) {}
public void windowIconified(WindowEvent event) {}
public void windowDeiconified(WindowEvent event) {}
public void windowClosed(WindowEvent event) {}
public void windowActivated(WindowEvent event) {}
public void windowDeactivated(WindowEvent event) {}
2. DrawToolCanvas Class:
import java.awt.*;
import java.awt.event.*;
public class DrawToolCanvas
extends Canvas
implements MouseListener, ActionListener {
String drawType="square";
Point lastClickPoint=null;
public void drawComponent(Graphics g) {
if (lastClickPoint==null) {
g.drawString("Click canvas first",20,20);
} else {
if (drawType.equals("square")) {
square(g);
else if (drawType.equals("circle")) {
circle(g);
public void actionPerformed(ActionEvent event) {
if (event.getActionCommand().equals("square"))
drawType="square";
else if (event.getActionCommand().equals("circle"))
drawType="circle";
repaint();
public void mouseReleased(MouseEvent e) {
lastClickPoint=e.getPoint();
public void square(Graphics g) {
g.setColor(Color.red);
g.fillRect(lastClickPoint.x, lastClickPoint.y, 40, 40);
g.setColor(Color.black);
public void circle(Graphics g) {
g.setColor(Color.blue);
g.fillOval(lastClickPoint.x, lastClickPoint.y, 40, 40);
g.setColor(Color.black);
public void mouseEntered(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mousePressed(MouseEvent e) {}
public void mouseClicked(MouseEvent e) {}
Any help would be appreciated!Some of the problems:
1) nothing calls drawComponent(Graphics g)
2) Paint(Graphics g) has not been overriden
3) myCanvas is declared twice: once as an instance variable to DrawToolFrame, and once local its constructor. Harmless but distracting. -
Problem With Swf File. Please Help!!!!
Hi! I recently got adobe flash cs4 and i tried to create swf wallpaper (flash lite 1.1), so everything looked good, untill i opened the file. The problem is its constantly blinking, like its refreshing with every second or frame or something. Then i transfered it to my phone and theres no change. I had the same problem with CS3...I attached the sample, if someone cares to see...Please can somebody help me??? Thank you!
I think (at a first look) that you should put a stop() command at each frame of your movie.
Playhead is running through your movie from one frame to another and back to beginning if you don't stop it with stop() command.
What I mean is:
in frame one of your movie put ActionScript: stop();
in frame two of your movie put ActionScript: stop();
etc.
If navigation through your movie is linear, like some animations then don't put this AS in frames, but it seems to me that this will solve your problem.
For more (if this isn't helping) upload your movie along with ActionScript. -
Hi.... Apple Support Communities...
I used Apple MacBook Air 2014 (13 inch) series with OS X Yosemite 10.10.2 version...
And I have a printer of Canon LBP2900...
My problem is that, I can't connect my Canon LBP2900 printer with my new OS X Yosemite 10.10.2 version.
My previous OS X Mavericks is working well with my Canon LBP2900 printer...
But when I upgrade it to OS X Yosemite 10.10.2 version, my printer is not working...
Anybody please help me how can i connect OS X Yosemite 10.10.2 version with my Canon LBP2900 printer....
Thanking you.... Your suggestion in this regards is highly appriciate...Your first step would be to upgrade to Snow Leopard (10.6). To do that, you would need to purchase the Snow Leopard DVD. Following that you could determine how much further you could upgrade.

IOS 8.0.2 update causing problems with wifi connectivity..please help
latest update having problems ...please help..!!!!!!!!!!
Just a quick snapshot of my chain of events. I’m currently on my fourth iPhone 6 Plus 64GB here in London, UK. Every time I have spoken to AppleCare and told them that I have gone through all the Wi-Fi troubleshooting methods possible they have asked me to get a brand new retail replacement as I’m within my 14 day return period. I’ve been experiencing the following issues:
Wi-Fi disconnects and switches to 4G (Restart required for temp fix)
Wi-Fi is still active but there is no traffic or activity– often when in sleep mode for long periods of time. (Toggle Wi-Fi on/off for temp fix)
Wi-Fi disconnects and cannot find any networks (restart required for temp fix)
This has been occurring on both iOS 8 and 8.0.2
The issues are the same on both my 2.4Ghz and 5Ghz networks
This is affecting my ip6+ and 5s (5s used to work perfect on ios7 on same networks) – My MBP-R and all other devices run perfectly on my network.
I spoke to AppleCare again yesterday and asked for their advice as its now my fourth iPhone in just under a month. This time they said that apple were fully aware of the Wi-Fi problem and that new repair tickets were not being raised for their engineers as they are already working hard to get this resolved. They also said they could see all the issues raised on the apple discussions boards which they usually don’t admit too! I asked what to do next and the advisor apologised and said this is clearly a software glitch and will be resolved in the next update. I asked for a timescale but unfortunately none was given.
As stated above I have tried all the troubleshooting methods discussed on forums and on tech websites but the only thing that gives me a stable connection without any disconnects (especially on my 6 plus) is turning cellular/mobile data off when I know I’m going to be on Wi-Fi for a sustained period of time (e.g. at home or work). I appreciate this is annoying but it’s the best temp fix until an update comes out.
Hope it helps everyone who is having issues with their devices that have cellular functionality.
Any comments welcome
