How to send two request in the same connection with HttpURLConnection?

As the title, I want to send two or more requests in the same connection with HttpsURLConnection..I wish all requests are in the same session.
My code is as following:
package test1;
//import javax.net.ssl.*;
import java.net.*;
import java.io.*;
public class httptest {
public httptest() {
public void test() {
HttpURLConnection uc = null;
String urlStr="";
urlStr="http://172.16.245.151/test/page1.jsp";
try {
URL u = new URL(urlStr);
uc = (HttpURLConnection) u.openConnection();
uc.setRequestMethod("GET");
uc.setDoOutput(true);
// uc.connect();
OutputStream out = uc.getOutputStream();
out.flush();
out.close();
catch (Exception ex) {
System.out.println(ex.getMessage());
public static void main(String[] args) {
httptest tt = new httptest();
tt.test();
The sample class just can send a request..Now we think of the sentence :uc = (HttpURLConnection) u.openConnection();
Obviousely, a HttpURLConnection can just have a Object of the Class URL, and the Class URL have no setURL mothed. So I can't use a HttpURLConnection to send two request.
I just want the HttpURLConnect is the same to IE...Do you understand what I mean?
Any helps will be appreciated...

HOW TO PUT TWO PANNEL IN THE SAME PAGE

HI ALL
I NEED TO KNOW HOW TO PUT TWO PANNEL IN THE SAME PAGE TO FULLY UTILIZE FULL PAGE AREA BECAUSE THE PANNEL WIDTH IS TOO SMALL , SO I WANT TO MAKE THE PAPER CONTAIN TO PANNELS VERTICALLY.
THANK YOU

So Barb,
I like to use multiple desktops and move back and forth between then using gestures. At the moment I have 5 open: Chrome, Firefox, Safari, Photoshop CS 6 and a desktop. I use "gestures" to navigate between them:
Mac Basics: Multi-Touch gestures - Apple Support
and I use Mission Control (F3) to move the various desktops around in the order I want them.
Mac Basics: Mission Control - Apple Support
So say I'm searching for a photo to open in CS 6, I find it on the open desktop then hit select "open" in CS 6 and go to that folder in the select pane.
Even right now I'm typing this in Safari and "gesturing" back to Chrome where I did the search about multi touch and mission control. I drag copy the URL there and gestured back here to paste the URL into this text.
If you did a lot of photo searches, I set professional clients of mine in Chicago up with dual monitors (In this case you'd have an external monitor on extended desktop.). So all you need to do is just glance over at the second monitor slide your cursor over there open stuff up find your photo and go back to Photoshop and open it up.
Hope this helps.

Hi
Can you please advise how to insert multiple queries in the same workbook in BI 7.0 web analyser.
Sarah

Hi,
You need to switch to design mode (BEx Analyser Menu - Design Toolbar - Design Mode). For each query that you want to embed, insert an analysis grid item in the workbook. Link each analysis grid to its corresponding data provider (query).
Hope this helps.

How to get a file in the same dir with the jar-executable

Hi,
I need to read/write a file that exists in the same directory with the jar-executable. How can i do that? I think that when i specify no path for the file, the file has to be in current path. (Is that right?)
Note: I do not know in which directory the jar and the file are.
Thanx in advance

Hi,
I need to read/write a file that exists in the same
directory with the jar-executable. How can i do that?
I think that when i specify no path for the file, the
file has to be in current path. (Is that right?)
Note: I do not know in which directory the jar and
the file are.
Thanx in advance
When you specify no path for the file, the file has to be in the directory where the virtual machine was started. ( the directory the java command was invoked in .)
If you can't control the directory in which the vm is started, but you know the name of the .jar file you can do the following. This trick takes advantage of the fact that if you are using classes in a jar file, the name of the jar file must be in your classpath.
public static String getPathOfJar( String nameOfJar )
throws Exception
StringTokenizer st = new StringTokenizer(
System.getProperty( "java.class.path" ) ,
System.getProperty( "path.separator" ) );
String jarfile = "";
while ( st.hasMoreTokens() )
String token = st.nextToken();
if ( token.indexOf( nameOfJar ) > -1 )
jarfile = token;
break;
if ( jarfile.equals("") ) throw new Exception( "Jar not found in classpath" );
String path = jarfile.substring( 0 , jarfile.indexOf( nameOfJar ) );
return path;
//To open a file in the same directory as the sun archive tools.jar
File f = new File( getPathofJar( "tools.jar" ) + "someFile.txt" );

Two profile two thunderbird at the same time with same user account

Dear,
I would use two Thunderbird at the same time for two different profiles with the same user accounts.
I using linux OS.
I was thinking of using:
# thunderbird -P profile1 &
# thunderbird -P profile2 &
But when launching the second command nothing happens.
Only brings in the foreground thundirbird already started.
If possible use this configuration now or in the nex future?

As a rule thunderbird only runs one instance of a profile.
However, there are a couple of options you could try.
You could use an addon to esily switch profiles:
* https://addons.mozilla.org/en-US/thunderbird/addon/profileswitcher/
there is more help here:
* http://kb.mozillazine.org/Run_multiple_copies_of_Thunderbird_at_the_same_time
It does say: 'Multiple instances is intended for debugging, so use it at your own risk'.
One method would be to use: Start > Run
"C:\Program Files\Mozilla Thunderbird\thunderbird.exe" -no-remote -P profilename
there is a space before '-no'
and also before '-P'
followed by a space and the profile name
You could create a shortcut/icon to run each separate profile.

WS-SDK Scheduling two instances of the same report with different params

I'm using the web services SDK for Business Objects XI 3.1 SP 2 to schedule reports. I've got it so that I can successful schedule a report with prompts, setting the value for the prompt and running the report.
However, I'm now trying to schedule two instances of the same report using a single call to BIPlatform.Schedule. It creates the correct number of new instances, the last of which is completely correct. The first one (and in fact if I do more than two all the rest except the last) lose the parameter value from the prompt and the schedule information and the type. So for example if I schedule two instances, both PDF, both for 8am tomorrow with parameters of 1 and 2, I get:
A Webi instance, scheduled to run immediately with no parameters specified and
A PDF instance, scheduled for 8am tomorrow with parameter 2
Any idea what I'm doing wrong?
Cheers,
Jack
Edited by: Jackson Pope on Feb 3, 2011 1:34 PM

Can you possibly post your code here that sets params and schedules? Also as you schedule 2 instances on a single report in a sinlgle biplatform.schedule call(): as you query for InfoObject what you actually query for a single report isn't it, or do you schedule a report template and reschdule it previous instance?

Send two signals at the same time to serial

Hi
I have a problem in that I want to control some relay boards by serial. The boards have an address byte (to determine which of the three relay boards) and a relay combination (four relays on each board). The .vi I will need to make will be sending data to the serial as a result of feedback from sensors (they are currently simply controlled by timers to simulate) so there is a good chance that there will be two relay addresses sent at the same time and consequently much confusion. The timed simulation demonstrates this possibility by switching all relays on at the start.
Is there a way of avoiding this? Any help would be much appreciated.
Many thanks
Alastair

Alastair,
When you say send to multiple boards "at the same time" exactly what to you mean? On a serial port only one byte at a time can be sent. You do not specify how many bytes are sent to each board to handle the addressing, the data, and any EOT (End of Transmission) characters.
I can think of two possibilities.
1. Relays are slow. If the transmission rate is fast enough, you could send messages to all relays sequentially over the serial port but still have the appearance of simultaneous activation of the relays. If the relays switch in 10 ms and each command contains 6 bytes, sending the data at 115 kilobaud would take about 1.5 ms for three boards. This would likely be close enough to simultaneous for relays.
2. Add a command similar to the GPIB GET (Group Execute Trigger). All devices on the bus respond to this command by executing a previously stored command. No addressing is used for this command. This does require that the relay boards be modified to respond to their address and to the common or group address and to store a command for later execution.

How to run two icalenders on the same computer?

How can i run two separate icalenders on the same computer? I have my own icalender with work, home, etc, and it's totally full. I am now running an artists collective and will publish the collectives icalender on the web. I don't, however, want to mix what will be a pretty busy calender with my own already too full one. Is it possible to run two totally separate calenders on the same computer?
macbook Mac OS X (10.4.8)

trsv,
Welcome to Apple Discussions.
Create two Groups...
Calendar 1:
Work
Home
etc
Calendar 2:
Collective Calendar
You can then switch which groups you wish to display by activating/deactivating the check mark in the Calendar source window.
That will also allow you to selectively publish the Collective Calendar.

How to process two files at the same time using BPM

Hi experts,
I have a Integration Process it takes two files one Header xml and one Lines xml. These files shoudl be processed at the same time because them will be mappend in a Idoc.
The realy trouble is that these inbound xmls never are executed at the same time. Then a IP is executed for each inbound xml.
This is the IP:
http://picasaweb.google.com/hose86/SapXi#5377539387476591346
This is related documentation:
http://help.sap.com/saphelp_nwpi71/helpdata/en/cb/15163ff8519a06e10000000a114084/frameset.htm
I try to do all what I know, but It don't work fine :S
Thanks in advance and Regards,
Jose Antonio.

Hi Jose,
Don't specify any end condition for fork step and check the start process check box in both the receive step.
Also put all steps inside the block.. so that the control step in deadline branch can throw exception and after that the BPM ends. As per the design now, if a deadline exception is raised (it will b handled) but after that the transformation step and send step is executed. There the BPM fails.

How to play two videos at the same time
