with regards......

This is a working code in one of my application, I modified it for better help
String command,classname;

Using packages breaks batch file

Hi there, I wonder if anyone can help me here.
I've been continuing work on somebody else's previous project, and everything is fine except for the batch file used to run the program from non development. I decided to use Eclipse to develop as opposed to the previous JCreator, and Eclipse gave an error unless I used packages, however this breaks the batch file
Here's the orginal text from the batch file -
java.exe -Xmx256m -classpath C:\InsTra\JARS\ant.jar;C:\InsTra\JARS\jaxen-core.jar;C:\InsTra\JARS\jaxen-jdom.jar;C:\InsTra\JARS\jdom.jar;C:\InsTra\JARS\saxpath.jar;C:\InsTra\JARS\xalan.jar;C:\InsTra\JARS\xerces.jar;C:\InsTra\JARS\xml-apis.jar;c:\InsTra\code_files InsTra
The batch file is located in C:\InsTra, the external JARS are in a JARS subfolder, and the java and class files are in Code_files. The main class is InsTra. I get the error NoClassDefFoundError
I've tried making the last bit Code_files.InsTra in case it needed to reference the package, but I'm new to this I'm afraid so have little experience of this sort of thing.
Any help is welcome
Thanks
Daniel

Then either your compiled class is not on the classpath, or you have not used the correct class name. Or both.
The classpath must point to the root of the package hierarchy.
The class name must include the package name (which is dictated by the package line at the top of your source file).
The compiled class file must be in the correct directory.
Given the information that you have provided, your class file should have the following path:
c:\InsTra\code_files\Code_files\It should also have the following line at the top of the .java file:
pacakge Code_files;Class names are case sensitive. Remember that the class path points to the root of the package hierarchy, NOT each of the directories containing class files. For example, if your classpath is thus:
c:\fooYour class file is in:
c:\foo\foo\Spong.classWith a package of:
package foo;And you execute it with:
java -classpath c:\foo foo.SpongThen it will work. The following will not:
java -classpath c:\ foo.Spong
java -classpath c:\foo\foo Spong
java -classpath c:\foo\foo foo.Spong
java -classpath c:\foo\foo Spong.class
etc.

Running a java program via a batch file

I am unable to run a java program from a batch file that I created.
spiderpackage.EntryPoint is a class file which I am trying to run with a -v option to output something.What should I do to get the output?
echo ^<html^>^<body^>
echo hello^<br^>
call java spiderpackage.EntryPoint -v
echo ^</body^>^</html^>

This has nothing to do with java programming. Have a look at the windows help for the call command.
The echo <html> stuff doesn't make sense. What's it for?
The command in you batch file should be:
java -cp . spiderpackage.EntryPoint -v
assuming that java is in the system path, and the EntryPoint.class is in a directory called spiderpackage which is a subdirectory of your current working directory

PL/SQL w/ Java to run OS batch file crashes Oracle

I followed instructions from "Ask Tom" on using PL/SQL with Java to execute an OS batch file. For testing purposes, my batch file does nothing more than display the date and time from the OS.
However, when I run the PL/SQL that executes this simple batch file repeatedly - anywhere from two to four times, the Oracle instance crashes abruptly. Nothing is written to the alert log. No trace files are created.
Here is a sample session:

Shortly after the second "run", Oracle crashed. All I received was the following error message:

The only thing I really changed was the reurn value from the java procedure. If it has a return value then it should be declared as a function, not a procedure. Since you probably (apparently) weren't using the return value I dropped it and made it a procedure.

Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;
I have used the following to load the class in Oracle 9ir2 DB:
loadjava -u [system/******@orcl|mailto:system/******@orcl] -v -resolve C:\Server\src\net\dev\Util.java
CREATE FUNCTION A1(drive IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'net.dev.Util.a1(java.lang.String) return java.lang.String';
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
The problem that it hangs when I execute the call to the function (I have indicated the line causing the problem in a comment in the code).
I have seen similar problems on other forums, but no solution posted
[http://oracle.ittoolbox.com/groups/technical-functional/oracle-jdeveloper-l/run-an-exe-file-using-oracle-database-trigger-1567662]
I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.

Java.io.filepermission error while executing a batch file from java prog

Hi,
i want run a java program which executes a batch file, both are in a jar file. while am trying this using webstart it shows error:access denied java.io.filepermission <<ALL FILES>>execute. why this happens how to rectify this.

Vinod

Clearly, it would be a security vulnerability to be able to do such a thing from the web w/o user granting trust to the application.
Java Web Start applications run in the Java SE secure sandbox unless they have been granted all-permissions by the user:
1.) sign all jar files.
2.) add <security><all-permissions/></security> to the jnlp file.
The user would then be prompted to grant trust to the applications.

Closing Console window while running Java application from Batch file

Hi all,
I have made a small application using Java swings,now i have made a jar file of my application and calling this jar file through batch file,when user clicks on that batch file it runs "java -jar applicationname.jar" command,but problem is that when i run that file from batch file it opens Dos console window at baclk of the screen which looks weird for a desktop application,i dnt want that Dos console window visible at the backend while my application is running,i have searched regarding this on google but found nothing usefull,if anybody can please help regarding that it will be a great releif for me,i have been stuck on this problem from last two days.
Thanks.

That'll pop up another consoleI'm under the impression that the console window he is seeing is the one which cmd.exe opens when it is executing the batch file. And that batch file won't return until the java process has completed because he didn't start it in the background to let the batch file continue and terminate.
So I don't think just simply substituting java with javaw will do much good either. Still think he needs a "start" command in that batch file.
So now he can try:
start java -jar ...
or
start javaw -jar ...Fair point

How to create a batch file for a java program?

I have a java project in JCreator and the project is organised into packages. I have also configured JCreator to provide 2 arguments to the main method when the project is executed.
I would want to create a batch file (.bat) for this project where the batch file can automatically use the arguments set in JCreator when the program runs.
How do I go about creating the batch file?

where the batch file can automatically use the arguments set in JCreatorThat all depends JCreator... can you get those arguments somehow?

HI,

First of all, you're OT.
Second, you can find this everywhere in the net.
If you got a manifest declaring main class (an classpath if needed), just create a file named whatever.bat, within same directory of jar file, containing:
javaw -jar ./WhateverTheNameOfYourJarIs.jar %*By the way, assuming a Windows OS, you can just double click the jar file (no batch is needed).
Otherwise use:
javaw -cp listOfJarsAndDirectoriesSeparedBySemiColon country/company/application/package/className %*Where 'country/company/application/package/' just stands for a package path using '/' as separator instead of '.'
Don't specify the .class extension.
Javaw only works on Windows (you asked for batch, I assumed .BAT, no .sh), in Linux please use java.exe (path may be needed, Windows doesn't need it 'cause java's executables are copied to system32 folder in order to be always available, see PATH environment variable if you don't know what I'm talking about) and use ':' as classpath (cp) separator.
The '%***' tail is there in order to pass all parameters, it only works on Windows, refer to your shell docs for other OSs (something like $* may work).
This way you have a command you can call to launch your code (instead of opening NetBeans just to see your app working). You could schedule tasks on it or just call it in any command prompt (hope you know what it is 'cause there have been people in this very same forum with no clue about it, if not just hold the 'Windows button' and press 'R', then type 'cmd' and run it).
Finally add dukes and give 'hem away.
Bye.

URGENT:- Running a batch file from java program

Author: pkanury
I am trying to execute a batch file from my java program using RunTime and Process . It can execute any dos command except for a batch file. Can anyone throw
some light ?? My code looks like this .....
cmd = "command.com /c X:\\grits\\scripts\\test.bat"; Runtime rt = Runtime.getRuntime(); Process p = rt.exec(cmd);
The weird part is that p.waitFor() returns a status of 0 implying that the cmd has been executed successfully. But that is not the case. And my batch file is as simple as - type "ADADA" > junk.txt
Any help would be appreciated.

I think it should work when you use a String[] array
instead of a single String:
String[] cmd = { "command.com", "/C", "D:\\batch\\do.bat" };
Note: If the batchfile creates any output (i.e. files),
they will be stored in the directory of the application
which calls the batch file, not in d:\batch\...

Iam not able to run a simple batch file from within java

This is how my code looks like.
It does'nt give me any error but I dont see the output from batch file which is suposed to be a simple redirection of dir command...
package mypackage1;
import java.io.File;
public class RunBatch
public RunBatch()
try{
Runtime rt = Runtime.getRuntime();
String cmd = "generate_invoice";
String path = "C:\\application\\Maps\\Reports";
File file = new File(path);
String[] envp = {""};
String[] args = {"C:\\application\\Maps\\Reports\\generate_invoice.bat"};
System.out.println("************ executing batch ");
Process proc = rt.exec(args);
System.out.println("************ batch executed ");
}catch(Exception e)
e.printStackTrace();
* @param args
public static void main(String[] args)
RunBatch runBatch = new RunBatch();
}

Runtime.exec() only can run executable files. Batch file is not an executable - it is a script executed by command interpreter (cmd.exe). So, you should execute "c:\windows\system32\cmd.exe /c C:\application\Maps\Reports\generate_invoice.bat".

To run a java program via a batch file,when called from a web server

REM This batch file runs the Spider with the [-v] option.
REM Lines 51 through 54 are simple DOS commands..they call the Spider
REM The location of the Spider package is the important piece of information here...
REM a batch file has access to the whole computer where the server resides.
setlocal
set JDK=C:\j2sdk1.4.1_01
set PATH=%JDK%\bin;.;%PATH%
CLASSPATH=%JDK%\jre\lib\*.jar;.;%JDK%\jre\lib\ext\*.jar;.;%CLASSPATH%
java spiderpackage.EntryPoint -v
endlocal
I am trying to run this batch file from my web server.I can see nothing on my browser.I can run the same program from my machine but unable to run from web server.what should I do?

I am making my question more clear...
I have a Windows batch (*.bat) file that echoes some html, then calls a java program the output of which is html as well, then echoes the final html.
To make sure that the java program gets properly executed, I set the necessary environment variables (e.g., JDK, PATH, CLASSPATH, etc.). The script looks something like this:
setlocal
set JDK=path_to_JDK
set PATH=path_to_java
set CLASSPATH=path_to_java_classes
echo ^<html^>^<body^>
call java foo
echo ^</body^>^</html^>
endlocal
The idea, of course, is to call this script through a browser, on a web server.
Curiously, both echo lines return to the browser just fine, but any output from
the java program (which just writes html to STDOUT) does not make it back.
Can someone explain to me why this is happening? How do I set things up so that the output (STDOUT and STDERROR) from the java program make it back to the browser?

I am trying to call this batch file from my web server but I am unable to capture the result.I tried to append the result to a file but It writes nothing to it.What should I do to proceed?

I am not entirely sure if this is analogous, but I once wrote a PHP script uner Linux that invokes java and returning the output. I found that it was necessary to pipe the output of the Java program from stderr to stdout in order to properly receive it in PHP. The command would be as follows:
java spiderpackage.EntryPoint -v 2>&1
The pipe syntax (2>&1) should be exactly the same under MSDOS. So add that, and then continue as normal (appending it to a file or whatever else you want to do). Hope that helps

Windows task scheduler to run batch file running a java program

I have created a batch file that runs my SendEmail program. The batch file is in the same directory as the java program. The only line in the batch file is
java SendEmail
This works fine from the command prompt but from the windows task scheduler it fails to function. Any help on how I can overcome this problem will be greatly appreciated.
THanks

Looks okay. The classpath is set, too, I guess? Btw, try running javaw instead of java. I may err, but I think it can show a console, so you can watch any error messages.
