Use ProcessBuilder to execute a java program with a file piped as input

Hi,
I am trying to execute a java program passing in input file as argument. I have to do this by forking a process and am using Processbuilder.
I have a main function which calls the executeCliTopologyDesigner method. I get a Java I/O exception
Caught IOException: Cannot run program "$JAVA_HOME/bin/java oracle.apps.fnd.provisioning.cli.TopologyDesigner ": java.io.IOException: error=2, No such file or directory
Can you please let me know if I am missing something?
Thanks,
pkrish
Code Snippet:
private synchronized void executeCliToplogyDesigner(String cliCommand, File tmp)
throws IOException, InterruptedException
{ File temp= writeDataInTemp(compDefName);
cliCommand = "$JAVA_HOME/bin/java oracle.apps.fnd.provisioning.cli.TopologyDesigner ";
ProcessBuilder pb = new ProcessBuilder(cliCommand,"<",temp.getCanonicalPath());
executeProcess(pb);

Hi,
I printed out the system environment variables PATH and CLASSPATH and it is as below:
Classpath :/ade/prprasa_prov_latest/fmwtest/tools/orajtst/home/lib/orajtst.jar:/ade/prprasa_prov_latest/jdev/src/abbot/dist/EXTENSIONS
Path :/ade/prprasa_prov_latest/fxtn/util/tools/ant/bin:/ade/prprasa_prov_latest/fmwtest/tools/orajtst/home/bin:/ade/prprasa_prov_latest/oracle/jdeveloper/jdev/bin:/ade/prprasa_prov_latest/javahome/jdk/bin:/usr/kerberos/bin:/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin:/usr/local/ade/bin:/OracleProd/oracle10g/bin:/OracleProd/oracle10g/bin:/OracleProd/oracle10g/bin
The Path does contain java.
I changed my command as I need a different classpath.
cliCommand = "/ade/prprasa_prov_latest/javahome/jdk/bin/java -classpath .:/ade/prprasa_prov_latest/oracle/provisioning/tools/lib/*:/ade/prprasa_prov_latest/oracle/provisioning/configframework/lib/*:/ade/prprasa_prov_latest/oracle/provisioning/framework/lib/*"
Caught IOException: Cannot run program "/ade/prprasa_prov_latest/javahome/jdk/bin/java -classpath .:/ade/prprasa_prov_latest/oracle/provisioning/tools/lib/*:/ade/prprasa_prov_latest/oracle/provisioning/configframework/lib/*:/ade/prprasa_prov_latest/oracle/provisioning/framework/lib/*": java.io.IOException: error=2, No such file or directory
Any ideas? Please let me know where do I post it if not here.

Batch prog to execute remote java program

hi all
i have one batch file which executes the local java program ....
but i want to execute a java program in a remote machine....
how do i do this..? kindly help

Well this is what I do in Windows (I use XP but it works in others):
First you have to make sure all the class files are in the same folder (duh)
Then you copy your java.exe from your jre folder into the folder with all your class files.
Finally, you create a shortcut to java.exe and add your class name to the command line on the shortcut.
Now all you have to do is double click on the shortcut and your program runs. Sure it's not that pretty but it works.

Executing new Java Program

Hey,
So I'd like to be able to execute another java program.
File directory = new File(".");

            }What am I doing wrong? I'm getting the error: "No such file or directory."

That is entirely up to you! That will be your entry point. If you are able to think of you application as two parts one server, one client part and you have no problems building the separate parts into "working" applications, then their respective main methods would be good enough as start-methods. It's just a name.
Really, the principle is as easy as this, Suppose you have a HelloWorld class (think Server) and a GoodbyeMoon class (think client) looking like:
public class GoodbyeMoon {
     public static void main(String[] args) {
          System.out.println("Good bye, Moon!");
}Then you're application can do this:
public class LoginMain {
     public static void main(String[] args) {
                // ... GUI to select MOON or WORLD
                if (userSelection == MOON ) {
                      GoodbyeMoon.main(null);
                } else {
                      HelloWorld.main(null);
}

Starting Java Program with a bash Shell script

Hi !
I know this is a Linux query but I am putting it on this site to get different answers.
I want to start my Java program with a shell script. Can anybody give me a proper script to start my Java program?
I am using RH Linux 7.3 and JDK 1.4.
Can I start the Java program without starting the terminal? Just like the Sun One Studio4 'runide.sh' script.
Please help.
Bye Niteen

assuming you have your PATH and CLASSPATH variables set correctly, your script should look like this:
#!/bin/bash
cd <project_dir>
java <class> &
example:
#!/bin/bash
cd ~/projects
java project1.main_package.MainClass &
of course you could add some more elaborated stuff like compiling files before running the program, etc.
if you dont like terminals, try running "nautilus" (it's like Windows Explorer). i never use nautilus (especially for running scripts), so i cant guarantee it will work, although i dont see why it shouldnt...

Please help with executing a java program from another java program

Hi, I have tried to execute a very simple java program which is printed out "Hello world" from another java gui program when the user click on the "START" button. However, I don't receive any print out on the terminal when they click it. These two programs are being developed in Unix environment. Here is the code that I am trying to use.
Runtime r = Runtime.getRuntime();
r.exec("java HelloWorld");
p.s. HelloWorld is java class of the HelloWorld.java

I think you have to luanch your MS Prompt first before executing the command.

Execute an external java program with Runtime, problem with classpath

Hi,
I m calling an external java program by the command:
Runtime.getRuntime().exec("java -classpath \"library/*\" org.mypackage.TestMainProgram param1 c:/input/files c:/output/files");All my classes are stored in the relative directory "library", and it contains ONLY .jar files. However, I keep getting errors like:
"java.lang.NoClassDefFoundError: library/antlr/jarCaused by: java.lang.ClassNotFoundException: library.antlr.jar at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)Could not find the main class: library/antlr.jar. Program will exit.Exception in thread "main" where "antlr.jar" is a jar file in "library". It is there but still the program keeps complaining it cannot be found. The problem applies to any jars in "library", ie.., if i have "mylib.jar" then it will complain "NoClassDefFoundError: library/mylib/jar".
Could anyone give some pointers please?
Many thanks!

Edited by: 836590 on 14-Feb-2011 09:03First, if you run from the command line
java -classpath "library/*" org.mypackage.TestMainProgram param1 c:/input/files c:/output/filesfrom the parent directory of library, does it work?
Despite what I said to Kayaman about Runtime.exec not expanding the asterisk, it looks like that's what's happening, so that you're getting
java -claspath library/aaaa_something_before_antlr.jar library/antlr.jar library/bbb.jar library/ccc.jar org.mypackage.TestMainProgram param1 c:/input/files c:/output/filesThat is, it *is* expanding the asterisk to a list of files in the directory, and the first one is being taken as the classpath, and the second one--library/antlr.jar is being taken as the class to execute. I'm certain this doesn't happen on Linux, so it must be a Windows thing.
Two suggestions:
1) Try single quotes instead of double.
2) Try the exec that takes an array
Runtime.getRuntime().exec(new String[] {"java", "-classpath", "'library/*'", "org.mypackage.TestMainProgram", "param1", "c:/input/files", "c:/output/files");Edited by: jverd on Feb 14, 2011 9:41 AM

Using ProcessBuilder to execute multiple commands.

I am having issues getting ProcessBuilder to execute multiple commands in windows.
As an example I would like to execute "dir /w" fallowed by "java.exe some.App arg1 arg2".
I can accomplish this from the command line by using "&".
Example: dir /w & java.exe some.App arg1 arg2 Or: dir /w & dir /c"
For internal commands (i.e. dir and cd) I know that commands in the array being passed to ProcessBuilder must be formatted like {"dir /w", "dir /c"}
see post: [http://www.java-tips.org/java-se-tips/java.util/from-runtime.exec-to-processbuilder.html]
Here is an example of one of the many things I have tried:
{code}
String[] commands = new String[]{"dir /w", "&", "java.exe", "some.App", "arg1", "arg2"};
ProcessBuilder pb = new ProcessBuilder(commands);
pb.start();
{code}
Any other ideas / what am I doing wrong?

Error while executing HelloWorld.java program

Hi All,
I am trying to execute the samples(HelloWorld.java) program from Jdeveloper and provided the following details in runtime.defaults:
CONTENT_DB_URL
ADMIN_USER_NAME
ADMIN_USER_PASSWORD
however getting the following exception:
FdkException:
Error Code: ORACLE.FDK.UnexpectedError
Detailed Error Code: ORACLE.FDK.FeatureNotEnabled
Trace Id:
info (NamedValue[]): null
can any one please help me to resolve this issue.
Thanks
Krrish.

See the Cleartext Authentication note in the running_client_samples.html file of the CDB devkit.
The default configuration for an out-of-box Oracle Content DB installation allows Cleartext Authentication only if SSL has been enabled (and the Web Services connection string begins with https). See the authentication topic for details.
To allow Cleartext Authentication to take place over standard (non-SSL) HTTP, set the Oracle Content DB domain property IFS.DOMAIN.WS.CleartextAuthenticationRequiresHttps to false using Enterprise Manager (Application Server Control). See the Content DB Administration Guide for details.
If the domain property above is not modified to false and Cleartext Authentication is attempted using using standard HTTP, an FdkException will be thrown:
ORACLE.FDK.UnexpectedError : ORACLE.FDK.FeatureNotEnabled
cheers
Matt.
