Sending POSIX signal to an external subprocess from a java program
I'm programing in forte for java under linux-mandrake, I've execute an external subprocess with the runtime and Process clases, I need to send the 2� POSIX signal to this external subprocess, I mean de SIGINT signal, I know that you can send a signal from a shell just doing:
Kill -2 pid // the SIGINT signal is the 2 POSIX signal
I know that there is another system-call like : kill(int signal, int pid) that any one can send from a c program.
Althought I don't know how can I get the pid of a suprocess, because I Know that there is the systemcall in c like:
int getpid() wich gives the pid of the current process, but I need to have the pid of a subprocess not the current one.
The thing is that I do not know how can I do it from a java program, I mean that to send a signal to a subprocess it will work using system-calls, but I do not know if I can insert system call in a java program, I've been thinking about doing it using a linux script like:
#!bin/bash
$a = pidof /home/maude-linux/bin/maude.linux
# this is the path of the process wich is running
kill -2 a$
and the run this script from a java program doing an exec(sh script.bin)
but by the moment I must be doing something wrong in the script because I find mistake in it, it gives me mistake in the assign sentence , I mean:
$a = pidof /home/maude-linux/bin/maude.linux
# this is the path of the process wich is running
I'm not used to program shell scripts, perhaps I'm doing something wrong, is there something wrong in this sentence?.
I would aprecciate some help about this, or if somebody have some idea how to do it in java, I repeat I need to send a signal to a external subprocess wich is launched from a java program by the process and runtime clases, and I need to send a SIGINT signal to the subprocess, I hope that some body can give some suggestion or some code explaining the situation
Are the portions of bash-code verbatim in your post?
When yes, they look suspicious!
Instead of
#!bin/bash
#!/bin/bash
would be better.
$a = pidof /home/maude-linux/bin/maude.linux
does not look good either.
If you have command "pidof" telling the pid based on the path name of the executable passed to it as its argument, you can have the output of this program in a shell script like this:
a=$( pidof /home/maude-linux/bin/maude.linux )
Then through $a you will refer to the value of the variable "a":
kill -SIGINT $a
A pidof script could look like this (apart from error handling):
ps -ef|awk '{if (NF>=8 && $8=="'"$1"'") print $2;}'
This works for me; your mileage may vary.

How to have an Oracle procedure send and receive value from a java program.
The below procedure is place inside a package. This procedure "get_extract_ready_headers " is selecting columns store_number, terminal_number, tran_number, tran_date, cust_id from the source REX_HEAD_EXTRACT table. This information is selected into a ref cursor. The data has cust_id field which is encrypted. How do I modify the procedure get_extract_ready_headers and accomplish 2 things?
1. Make this procedure to read the "cust_id" value from the source table and send the value to a Java program "getheaderinfo" (this java program decrypts the cust_id field).
2. When we get the unencrypted value back from the Java program, make the procedure accept this decrypted value and use it to update CUST_ID value in the target table TRAN_HEAD table. I am using Oracle 11.2.0.2, and TOAD 10.5.1.3.

INSERT INTO table_b( cust_id, <<other columns>> )
SELECT SomeJavaPgm( a.cust_id ), <<other columns>>
FROM table_a aIf SomeJavePgm is not a Java stored procedure, calling it from PL/SQL becomes much more complicated. You would need whatever machine hosts this program to expose an appropriate API (for example, a web service interface) that you could invoke via UTL_HTTP). You'd need to tell us what that API was, however.

Help Me! How to send sms from a java program with a pda connected to system
help me ,
I am new in JavaME. I have to send sms from a java program, A PDA is connect to the system. Can some one help me to make that program which interact with PDA connected to system and send sms to any mobile or pda phones.user12873853 wrote:
I believe JavaMail API will help in sending the mails and SMS through SMTP server. Sounds more like false hope than belief to me. The only way that would work is if you have an SMS gateway that allows communication through SMTP. Doubtlessly some exist (searching for 'JavaMail sms' through google certainly seems to indicate this), but if you have to ask you don't have one.
And that exactly where you are stuck: to send SMS messages you need an SMS gateway. That will be the first thing you have to shop for, until then there is no reason to think about code, protocols or implementations. It can be as simple as hooking up a mobile phone, but then you cannot send bulk messages of course. Most likely you'll need to shop around for a partner that has an SMS blasting service you can use. -
How can I pass system commands from a java program? Urgent!

How to run a remote application (Non Java) from a Java program
Could you please tell me how to run a remote application (Non-Java) from a Java program without using RMI. Please tell me know the procedure and classes to be used.
Cheers
Ramwhat do you mean remote application.In the other pc or in your pc just apart from you application?
If the application is in your pc,the method which the upper has mentioned is
a good one!
But if the application you want to run is not in your computer,the method can't do. And you can use socket with which you can build an application listening some port in the pc which contains the application you want to run .When you want to run that application ,send the Start_Command to the listening application.Then listening application will run the application with the help of the method the upper mentioned. -
Executing a stored procedure from a java program
Hi.. how can i call a oracle stored procedure from a java
program. the OSP has four IN parameters and one OUT parameter(a
cursor). when i try this way.. i get an error
con = DriverManager.getConnection(url, "stored", "stored");
CallableStatement cs =
con.prepareCall(
"{call stored_proce_1(?,?,?,?,?)}");
cs.registerOutParameter(1, OracleTypes.CURSOR);
cs.setString(2, "14541");
cs.setString(3, "gen");
cs.setInt(4, 0);
cs.setInt(5, 5);
ResultSet rs =cs.getResultSet();
while(rs.next()){
System.out.println(rs);
appreciate ur help.
qsI'm no expert on this, but I have a similar call where I fetch
an Oracle REF CURSOR from a call to a stored function. If you
fetch the cursor as an Object from your CallableStatement, you
can then cast it to a ResultSet e.g.
mystatement.executeUpdate();
ResultSet rs = (ResultSet) mystatement.getObject(1);
Then you should be able to loop through your ResultSet as usual.
Good luck!

Running curl command from a java program using Runtime.getRuntime.exec
for some reason my curl command does not run when I run it from within my java program and errors out with "https protocol not supported". This same curl command however runs fine from any directory on my red hat linux system.
To debug the problem, I printed my curl command from the java program before calling Runtime.getRuntime.exec command and then used this o/p to run from the command line and it runs fine.
I am not using libcurl or anything else, I am running a simple curl command as a command line utility from inside a Java program.
Any ideas on why this might be happening?thanks a lot for your response. The reason why I am using curl is because I need to use certificates and keys to gain access to the internal server. So I use curl "<url> --cert <path to the certificate>" --key "<path to the key>". If you don't mid could you please tell me which version of curl you are using.
I am using 7.15 in my system.
Below is the code which errors out.
public int execCurlCmd(String command)
String s = null;
try {
// run the Unix "ps -ef" command
Process p = Runtime.getRuntime().exec(command);
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
// read the output from the command
System.out.println("Here is the standard output of the command:\n");
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
// read any errors from the attempted command
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);

How to execute unix command from the Java program running on Windows
Hello,
I need to
1. Execute a unix shell script from a Java program running on the Windows.
2. I also need to capture the output of this shell script in my program.
Please suggest me how to achieve this.
Thanks in Advance.Hi...
Something is missing here
If you want to execute a shell script in windows that not posible unless you find or develop a unix shell script parser for windows.
But if you are trying the execute a unix shell script on a remote unix computer from your java program running on a windows platform you can do that by logging on to the UNIX terminal which is running on port 23 I think.
You can test this using telnet tool on windows
just type on command prompt
telnet <ip of the unix pc> <port number this case 23>
you should get the unix terminal. If that works you can do the same through java or you can directly conect to port 23 of that pc using sockets that way your program will be platform independant -

How can I execute a batch file from my java program

Can someone help me or direct me to a link,
How can I execute a DOS batch file from my java program?
ThanksYou will need to grab a handle to the process's
outputstream so u can see its output.The OP didn't mention any output from any batch file;
nor any input for that
matter,so lets not complicate matters here for now
ok?Actually I think this is essential to see whether it works or not. It's either that or do some manual check to see whether it ran, which is not exactly elegant, and in some cases this may not be easier than simply writing the output stream code, or in fact it may be impossible to check manually.
I'm sure it wasn't intentional that your post appeared to be bristling with attitude. -
How to read files on server from a java program?
Hello,
I am fairly new to JSP programming. I have an issue with reading files. I am trying to call method of a normal java file from a jsp program. The method I am trying to call does some IO operation on Files. I have the files in the same directory as my class files on server that is in WEB-INF/classes folder. In my java program, I am giving just the file name to open because the files and the classes are in the same directory. But this is not working.
What exactly should I do to read a file from a java program, that is running on the server?
Any help is appreciated.
Thanks,
KrishnaString realFilePath = application.getRealPath("/WEB-INF/myFile.txt");
File fileToOpen = new File(realFilePath);
out.println(fileToOpen.getAbsolutePath() + ": exists? " + fileToOpen.exists());in this case "application" is a reference to the ServletContext.
It is an implicit variable in a JSP. In a servlet:

Calling servlet from a java program
Hi
I need to call a servlet's doPost() method from a java program. I have a specific situation, where I need to call servlet from a java program. DUring this call I need to pass a file and two string to the servlet. Servelt after receiving the file and string uploads the file to the server at a specified location. I am stuck up as how to call servlet from a java program instead of a HTML or JSP.
Can anyone help me to start with this.
any suggestion is welcome.You have to establish a URLConnection with servlet from your java program.
URL servletURL = new URL("http://localhost:8080/Myservlet?str1=abc&str2=def");
URLConnection servletConnection = servletURL.openConnection();you can get the objectOutputStream
ObjectOutputStream oos = new ObjectOutputStream (servletConnection.getOutputStream());
oos.writeObject(your file object);-------------------------------------------------
In the servlet u can get the strings using request.getParameter("str1");
In the servlet u can get the strings using request.getParameter("str2");
file = new ObjectInputStream (request.getInputStream()).readObject()a lot of resources are available on this ...
hope this helps :) -

Any help is greatly appreciated,
Jacob NikomThank you for your suggestion.
I tried it, but got the same result. I think the difference in the syntax is due to the Oracle versus SQL92 standard
conformance. Your statament is the Oracle version and mine is the SQL92. I think both statements are acceptable
by the Oracle.

How to display a oracle table from a java program?
How to display a oracle table from a java program.
Hello friends, I have written a Java program, using oracle 10g as backend.
I want to display a oracle table as output. Im not getting how to display oracle table as a output table.. Pls help me
Thank youjayanthds, you're not going to get a satisfactory
answer to this here. it's too big a task to justbe
quickly outlined in a forum - the reply "all youneed
to do is to query you table and return it asJTable"
is worthless, for example, since the solution to
any problem can be distilled to such a
soundbite, if need be. doesn't make the solutionany
simpler
essentially you're asking "how do I write adatabase
application?". all you'll get is snippets of code
that, when fitted together, will eventually helpyou
do this, but you'll spend days and days comingback
saying "right, I've done that, now what?" until
either you or the forum gets frustrated with the
whole affair and the process stops
there are entire books written about this subject,
and countless tutorials and guides on theinternet.
you're better off going down that routehehehe.well, it's true! I used to have a manager that would outline the solution to a problem in a few lines of pseudocode, and then firmly believe that the actual solution would be just as brief and simple. shame his pseudocode included such lofty abstractions as "reformat all data"
