How to run native program with Java program?
Hello
I've got following problem. I'd like to write file browser which would work for Linux and
Windows. Most of this program would be independent of the system but running programs not. How to run Linux program from Java program (or applet) and how to do it in Windows?.
Cheers
Try this:
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("ls -l");
InputStream stream = proc.getInputStream();
InputStreamReader isr = new InputStreamReader(stream);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ( (line = br.readLine()) != null) .....
"if the program you launch produces output or expects input, ensure that you process the input and output streams" (http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html)

How to run sscript shell with java program
Hi everybody,
i want to know how can i do to execute a script shelle (bash) with program java (if it s possible)
for example this script:
#!/bin/bash
echo "hello"
can i run it with java program or i have to make dome modifications .
thank you for your help in advance.Well, if you want to be portable across platforms, you should write as much code in Java as possible and not rely on native scripts (I'm sure your script is more complex than this 'echo' example ;-) ).
Having said that, you can use the java.lang.Runtime class and in particular its various exec() methods.
Try something like this:
Process p;
try {
p = Runtime.getRuntime().exec("myscript.sh");
} catch (IOException ioe) {
}You can then "interact" with the spawned process with the Process object returned by the exec method.
Note you need to have the appropriate security rights.
For more details, look at the API documentation here:

How to run an applet with .java files in 2 dirrerent directories ?
I have an applet with :
5 .java class files and its .html file in one directory and
2 .java class files ( with identical names) and its .html file in another directory .
How do I go about executing this applet ? In the past all the applets
I have run had all the classes in one directory.
Thank you in advanceIf you want them both in the same page, put both applet tags in 1 page,
I could do that but both directories have a SpaceDunes.class
and both directories have a Shot class (diffferent immplementations
but the same name)
so the applet tag
<APPLET CODE="SpaceDunes.class"
CODE="SpaceDunes.class"
This can't be the right approach ? ?
Thank you for your advice

How to run labview program in debugging mode in windows 95 version
Respected all,
I am facing probelm while running probe.vi.
I received this command "connection to acquisition board was not found" when i run labview program.
I am using labview 5.1, fieldpoint FP 1000, NI-DAQ 6.5, Field point explorer version 1.6, Measurement and Automation Explorer 1.0.1.
I would kindly request you please help me how to run my program probe.vi in debugging mode in windows 95 version, so that i can locate where error occurs.
Thanking You
Yours faithfully
M.VijayRespected Norbert,
Thank you very much to for your help.
Norbert : Possible reasons are e.g. wrong IDs for measurement devices. If the error is connect to the FieldPoint, it is possible that it isn't configured correctly.
I am using Field point explorer 1.6, The Field point instrument FP 1000 and RS-232 port is using. It is confirmed that the field point instrument is working properly by LED light indication test.
Norbert: It sound like you are using DAQ devices (like PCI MIO 6952E) in the application. Are you sure that you select the correct device ID for this?
I am asking you to know, If i using Labview and Fieldpoint instrument FP 1000 to monitor my parameter interms of All, Channel 0, Channel 1, Channel 2, Channel 3, Channel 4, Channel 5, Channel 6, Channel 7 for my measurement.
But now i need to solve the command connection to acquisition board was not found, The expert say this command is due to there was no AT-AO-10 Analog Output board was present in CPU.
I do not find AT-AO-10 Analog Output board in my CPU, Previously the instrument was worked perfectly by other person who assembled everthing to measure temperature.
The only aswer know send by previous person is if my task does not imply the use of a DAQ you probably have to locate where the DAQ driver is called and exclude it from the program. try to run the program in debugging mode so that you can locate where the error occurs.
I do not know how to proceed his instruction. So i would kindly request you to please help me to solve my probelm.
I also removed AT-AO-10 software from device manager >> Data Acquisition system >> AT-AO-10 just now.
I also find GPIB version 1.30, when i remove in add or remove program, it say that Error removing the GPIB.
I am eagerly waiting for your help.
Thanking You
Yours faithfully

NetBeans IDE: How to run a prog with arguments
Hi:
I have the following code that copies contents of inputFile to outputFile.

String dir_sep = System.getProperty("file.separator");
String inputFileLoc;
inputFileLoc = args[1];
File outputFile = new File("C:" + dir_sep + "temp" + dir_sep + "out.xml");

Thanks a lot in advance!sourcecode's filenode -> ContextMenu -> Properties -> In the second block, there's one called "Arguments" -> Edit that -> You're done.

How to run JavaFX Jar with JRE 7 on MAC OS Lion 10.7.5 ?
I had java 1.6 installed on my MAC OSX Lion 10.7.5. When I am trying to run that JavaFX application jar
java -jar application.jar
It always shows a dialog "The application require a newer version of Java Run-time" with download link. Even I have downloaded and successfully installed it on my MAC machine but it still shows me the same window.
It installed jre-7u10-macosx-x64.dmg but java -version is always point to 1.6.
Then I searched for Java Preferences to point the current JRE 1.7 but I could find Java Preferences at Applications -> Utilities -> Java -> Java Preferences.
I found an Java Icon on System Preference. When I am trying to open that widow it's showing me error -- the java control panel opens in a separate window and nothing happens when we click on Re-open the Java Control Panel.

I would like to know -- how to run JavaFX jar with JRE7 on MAC OS Loin 10.7.5? Is their any other way to run the JavaFX application JAR with JRE7?To find a copy of LP7 you would need to look for a copy on eBay.. However, the protection method used with LP7 no longer functions so you cannot register it and therefore you cannot use it. unless you have already registered LP7 yourself in the past using the security key dongle provided
Any version of LP7 from a torrent would be an illegal (and most likely non working) version due to the protection that was used at that time... and so posting about it here, was not be wise.
So.. thats why my previous answer was so brief... Simply put, you cannot use LP7 unless you already have a validated and registered security dongle... even if you found a copy of LP7 somewhere
The only practical solution is to find some kind soul who already has a working version of LP7 installed, that you can send the projects to... for them to do the conversion for you.
I would, but I no longer have LP7 installed here on any of my testbed Macs... -

Can not I run the Jar file with Jre7?Yes, you can.
This may be because I have downloaded the JRE 1.7Yep, that's correct, the java_home command only works for jdk's - sorry for the confusion.
For jre7+ versions, only a single Oracle jre version is allowed to be installed on the machine at a time - making a tool like java_home redundant for jre checking.
Weirdly, jre7u10 does not supplant the Apple Java on the command line path by default. If you just type java -v, then the Apple java version will displayed if you have an old Java 6 from Apple and a new Oracle jre7+.
The Oracle jre is always located under (also somewhat strangely):
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/javaTo test jar launching, I used the willow JavaFX browser pre-release jar available here:
http://code.google.com/p/willow-browser/downloads/detail?name=Willow-0.1-prerelease.jar
Then I launched the jar from the command line using:
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -jar Willow-0.1-prerelease.jar The JavaFX jar ran fine on jre7 with the above machine.
The test machine was running Mac OS X 8 with Oracle jre7u10 installed as well as the Apple Java 6 runtime, but no Oracle jdk7+ installed. -

How to run execute immdiate with variables
Hi friends,
How to run execute immdiate with variables in v_stmt below?
I dont know how to declare the value of i here.
Set serveroutput on;
DECLARE
i VARCHAR (20);
v_stmt VARCHAR2 (100);
CURSOR c
IS
SELECT sqlid FROM temp1;
BEGIN
OPEN c;
LOOP
FETCH c INTO i;
EXIT WHEN c%NOTFOUND;
DBMS_OUTPUT.put_line (i);
v_stmt := 'select * from table(dbms_xplan.display_cursor('&i',null))'
execute immediate v_stmt;
END LOOP;
CLOSE c;
END;
/Regds,
Kunwar.You first need to use a bind variable (named ':v' in SQL statement in my example):
set serveroutput on;
DECLARE
i VARCHAR (20);
v_stmt VARCHAR2 (100);
CURSOR c
IS
-- modified for a quick test
SELECT sql_id FROM v$sql where child_number > 2;
BEGIN
OPEN c;
LOOP
FETCH c INTO i;
EXIT WHEN c%NOTFOUND;
DBMS_OUTPUT.put_line (i);
v_stmt := 'select * from table(dbms_xplan.display_cursor(:v,null))';
execute immediate v_stmt using i;
END LOOP;
CLOSE c;
END;
/However because your SELECT statement returns several rows you need to adapt your code to process all rows returned (as already suggested in first reply to your message).
Instead of using PL/SQL, I recommend to generate a SQL file using only SQL and then to run the generated SQL file.
For example:
spool edx.sql
set serveroutput on
declare
v_stmt varchar2(100);
v_q char(1):='''';
begin
dbms_output.put_line('spool edx.log');
for s in (select sql_id from v$sql where child_number >2)
loop
dbms_output.put_line('select * from table(dbms_xplan.display_cursor(' || v_q || s.sql_id || v_q || ',null));');
end loop;
dbms_output.put_line('exit');
end;
spool ofThis generates a SQL file similar to :
spool edx.log
select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null));
select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null));

How can i create messenger with java tv API on STB
deal all.
how can i create messenger with java tv API on STB.
how can Xlets communicate each other?
how?
i am interested in xlet communications with java tv.
is it impossible or not?
help all..You can create a messenger-style application using JavaTV fairly easily. JavaTV supports standard java.net, and so any IP-based connection is pretty easy to do. The hard part of the application will be text input, but people have been using cellphone keypads to send SMS messages for long enough that they're familiar with doing this. This doesn't work well for long messages, where you really need a decent keyboard, but for short SMS-type messages it's acceptable.
The biggest problem that you need to work around is the return channel. Many receivers only have a dial-up connection, ties up the phone line and potentially costs people money if they don't get free local calls. Always-on return channels (e.g. ADSL or cable modem) are still pretty uncommon, so it's something that you nee to think about. Of course, if you do have an always-on connection then this problem just goes away.
This is really one of those cases that's technically do-able, but the infrastructure may not be there to give users a good experience.
