Executing SQL command in Java on Linux OS

when i am running a java class file from cmd line,
in that java file i am using a SQL statement, like
select * from emp where empname='uday'
here its not accepting the single quote('), its
ignoring single quotes
can any one help meIf you were using a prepared statement then this would be irrelevant. I suggest you take a look at one before you have to right some larger queries.

Executing shell commands from Java.

I want to execute shell commands in Java using the Runtime.exec( String ) method.
The method works fine under Linux OS, but under Windows '98 the method didn't work at all!
For example the following call: Runtime.exec( "dir" ) throws an exception showing that the command was not completed. If I replace dir with ls under Linux all is good. What is the problem with the Microsoft Windows '98 ? Is there any solution at my problem ?!
thx in advance!

hey JSarmis,
You can help me... "ls" doesn't work for me on linux.. using Runtime.exec, some commands work, others don't... you may hold the key to what i need? How did u get "ls" to work?

Executing UNIX command in Java

I am having problems executing a command in Java. Here's the code I have for executing:
Process p = Runtime.getRuntime().exec(cmd);

     while((display = input.readLine()) != null)
                         num_1 = Double.parseDouble(display);
                         percent = (num_1 * 100) / (50000000);
                    flip = 1;
                    catch(IOException e)

A DESCRIPTION OF THE PROBLEM :
Unable to run signed applet with Netscape 4.79 and IE5.5
native JVM.
REGRESSION. Last worked in version 1.3.1
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.compile program and copy class files to a temp directory
2.sign the applet for Netscape as follows:
signtool -k aok -d \progra~1\netscape\users\viravan -Z
FIO.jar temp
3.sign the applet for Internet Explorer as follows:
cabarc -p n FileIO.cab FileIO*.class
setreg 1 true
makecert -sk aok -n "CN=aok" aok.cer
cert2spc aok.cer aok.spc
signcode -j javasign.dll -jp LOWX -spc aok.spc -k aok
FileIO.cab
Run the applet with the following HTML file:
<html><head><Title>Self-Signed Applet</Title>
<script>
document.layers ? parm=1 : parm=0;
</script>
<body>
This file I/O applet lets you read and write to the user's
local disk.<br>

How to execute dos command in Java program?

In Perl, it has System(command) to call dos command.
Does java have this thing?
or any other way to execute dos command in java program?
Because i must call javacto compile a file when the user inputed a java file name.

Look in the Runtime class, it is implemented using the Singleton design pattern so you have to use the static method getRuntime to get its only instance, on that instance you can invoke methods like
exec(String command) that will execute that command in a dos shell.

Gerrit.

Help with executing windows command in java

hi, i am trying to execute dos command in java. currently i am trying simply to create a folder in the current directory.
here is the code snippet:
try {
Process p = Runtime.getRuntime().exec("md myFolder");
} catch (IOException io) {
io.printStackTrace();
i have also tried using "mkdir" instead of "md". but my code just throws an exception that says:
java.io.IOException: CreateProcess: md myFolder error=2
what have I done wrong? thanks in advance

try {
Process p = Runtime.getRuntime().exec("cmd /c
mkdir myFolder");
catch (IOException io) {
io.printStackTrace();hey! that code worked out perfectly. so "cmd" is needed to run dos commands? i searched through the net, but most of the examples that i were able to find did not include "cmd".
if it wouldn't be too much trouble, what is the option "/c" for?
i would also like to add that "mkdir" also works. The problem was the missing "cmd /c". Thanks guys for your help! I really appreciate it.

SQL2005 cluster error MDB-05053 Errors when executing sql command: p nr="

Hi all,
We are migrating from 32 bit to x64 bit machines. SQL 2005 database on windows 2003.
I am trying to install E 4.7-200 SR1 on the clustered nodes. The installation manuals for 4.7 are very old and there is nothing for SQL2005 installation.
Now that some how we were able to have SQL up and running in clustered environment (It only took 10 days), After installing CI, I am not able to deploy the database and database creation phase is failing with the following error:
MDB-05053 Errors when executing sql command: <p nr="0"/>.
I am heavily relying on our server managment team on clustering and hoping they have done a good job, However I need some guidelines which can help me in verifying what they have done is correct and meets SAP and SQL requirments and issues we are facing is actually install problems not cluster.
SAP install manuals are not detailed in this regards. Also manuals are out dataed and they only show the sql 2000 clustering pre-requisit for 4.7 installls.
Can any one with clustering experience please help.
Calling out NPC, As his sql installation and upgrade manual has helped me with stand alone installs, Hoping he has some thing for clustering as well.
Regards,
KG

Hi,
What installation CD/DVD are you using?
Try look at SAP note [924288|https://service.sap.com/sap/support/notes/924288],
and note [969699|https://service.sap.com/sap/support/notes/969699],
and note [967124|https://service.sap.com/sap/support/notes/967124],
and note [106275|https://service.sap.com/sap/support/notes/106275].
In special the last note say at the end:
"3. You must use the 51031444 CD to install Enterprise 4.7 on an x64 platform with SQL Server 2005. This CD installs the central instances and database instances. To convert the A and B nodes in MSCS, use the SAP NetWeaver 04 SR1 installation master CD or DVD."
Hope this helps
Regards
Rolf

        String command = "ls";
        Process child = Runtime.getRuntime().exec(command);
        // Execute a command with an argument

Execute dos commands through java

Hi,
Im trying to execute dos commands through java like
          try {
               java.lang.Runtime.getRuntime().exec("cmd /c cls");
          }catch(IOException e){
               System.out.println(e.getMessage());
          }Not sure if its possible? however
open notepad would work
          try {
               java.lang.Runtime.getRuntime().exec("notepad");
          }catch(IOException e){
               System.out.println(e.getMessage());
          }Im trying to execute a cls commands to clear screen but without luck.

The question is, which shell do you want to clear?
I don't really know, but it could be that Runtime.exec executes its command in a new shell window...

Executing the top command through Java in linux

I am trying to execute the top command in Java as
Runtime.getRuntime().exec("top -n 1 >a.log");
But the command is not working in linux only through java.When i run the same command through the prompt it is working fine.Also all other commands are working fine.Is there any issue with top in linux?

Execute NMAP command in java

Hi all
i would like to execute a NMAP command from java. So i wrote the following method:
public void execute(){
try {
Runtime r = Runtime.getRuntime();
String command = new String("nmap -sU -p 161-162 "+this.network+" -oX /home/hippie/blaTEST.txt");
System.out.println("command: "+command);
Process p = r.exec(command);
System.out.println("executed nmap");
catch (Exception ex) {
System.out.println(ex);
Now i have the problem that i have to be root user in linux to execute this command. So it doesn't work the way i implemented it
Could someone explain me how i have to implement it?
I think the same problem could occur in Windows if i'm not Admin, is this right?
Thanks Angela

Source sql command in java

Hi, is there any way to run source sql command direct in java, or i have to write a method to do that.

statement, but why java doesn't use such a method
and save our time.IMHO this would be outside (way) the scope of a
general purpose programming language like Java. And,
I would argue, outside the scope of the JDBC
packages.
It might be in the scope of a utility package but
really it is a job for a database utility.Exactly. For instance, the Hypersonic database (hsqldb.jar) comes with a SqlTool class (or something like that) that you can call. That class will read and execute a .sql script. Other database products may come with other similar tools.

I have a nice piece of Java code that allows you to execute OS commands from within a PL/SQL block in Oracle. If you need the code send me an email. I know it works in Unix and it should work on most platforms.
