How to get oc4j version from Java program

i have the following in my Java Program
Runtime r = Runtime.getRuntime();
Process p = r.exec("java -jar oc4j.jar version");
and then i try to read the InputStream from the Process p.
but this line is not executing, it returns the following error.
Unknown switch: ?version, type java -jar oc4j.jar -? for help
if i change it to ----------
Runtime r = Runtime.getRuntime();
Process p = r.exec("java -jar $ORACLE_HOME/j2ee/home/oc4j.jar version");
then i get another error :
Exception in thread "main" java.util.zip.ZipException: No such file or directory
at java.util.zip.ZipFile.open(Native Method)
at java.util.zip.ZipFile.<init>(ZipFile.java:112)
at java.util.jar.JarFile.<init>(JarFile.java:127)
at java.util.jar.JarFile.<init>(JarFile.java:65)
but if i cd to /oracle/j2ee/home and then run the command java -jar oc4j.jar version, then it gives me the right output with the right version, but for some reason the samething from inside the java program is giving me errors,
please help. i just need to read the oc4j version running on the server and display it in JSP.

Process p = r.exec("java -jar oc4j.jar version");The character before "version" should be a hyphen; yours is not.
Process p = r.exec("java -jar $ORACLE_HOME/j2ee/home/oc4j.jar version");
then i get another error : Exception in thread "main"
java.util.zip.ZipException: No such file or directory
at java.util.zip.ZipFile.open(Native Method)
at java.util.zip.ZipFile.<init>(ZipFile.java:112)
at java.util.jar.JarFile.<init>(JarFile.java:127)
at java.util.jar.JarFile.<init>(JarFile.java:65)One more problem here: $ORACLE_HOME will be not be interpreted in the runtime.exec even if it is defined as an environment variable. So you get an error that tells you oc4j.jar is not found.
Hope this helps you.

How to Call .XDO file From Java Program

Hi,
I have developed a report in using BI Publisher version 10.1.3.
I created the report and it only created XDO files. If I want to call XDO file from Java program how I can do that.
What are the APIs available to do that.
Thanks
-Ashutosh

Hi,
the JavaAPI didn't work with the xdo-Files. But you can create a proxy stub for the Web Service API of BI Publisher which uses the xdo's in the repository.

How to get return value from java and read by other application?

i want to read return value from java and the other application read it.
for example:
public class test_return {
    test_return(){
    public int check(){
        return 1;
    public static void main(String args[]){
       new test_return().check();
}from that class i make as jar file. How to read the return value (1) by other application?
thx..

If your installer is requiring some process it invokes to return a particular value on failure, then the installer is seriously broken. There are a bazillion commands your installer could invoke, and any of them could fail, which in turn could invalidate the entire install process, and any of them could return any value on failure. The only value that's consistent (in my experience) is that zero means success and non-zero means failure, with specific non-zero values being different in different programs.
About the only control you have over the JVM's exit code is that if your main method completes without throwing an exception, the JVM will have an exit code of 0, and if main throws an exception (either explicitly or by not catching one thrown from below), it will be non-zero. I'm not even sure if that's guaranteed, but I would guess that's the case.
EDIT: I'm kind of full of crap here. If you're writing the Java code, you can call System.exit(whatever). But nonetheless, if your installer requires certain exit codes from any app--java or otherwise--you have a problem.

Hi,
Have your tried pr.exitValue() ?
I think you also need a finally block that destroys the subprocess

How to get the parameter from Java Script into the Parameter crystal Report

Hi All,
Crystal Report is integrated with Oracle 10g. I created the base SQL query for col1, col2, col3 and col4. Java Script pass parameter value (185) to Col1.
My question is how to create crystal report to make Col1 as parameter and how to get the parameter value 185(Col1) from Java Script. Is there any additional code I need to include in the crystal report?
FYI.
Java script sends the right parameter value.There is no issue in java script.
This is an automatic scheduled process when batch runs, Java script should pass the parameter value and the crystal report should get the value and produce the output report.

Not sure if this is an application question or if you are trying to hook into Crystal Reports parameter UI? If the later then no option other than report design. If an application then I can move this to the Java Forums.
If you are asking how to alter the parameters I suggest you remove the Java reference and post a new question so it's not confusing the issue.
Please clarify?

How to get stylesheet object from JAVA RESOURCE stored in DB

Hi,
I stored a xslt file in the database and have a JAVA RESOURCE file now. How can i get a stylesheet object from this resource file?
I took the following class to get an impression how to get the contents of the resource but -although the name of the resource was spelled correctly- i got a file not found exception.
Whats wrong?
public class PrintRessource {
public static void print (String p_ressource){
try {
Class c = PrintRessource.class;
System.out.println(c.toString());
InputStream file = c.getResourceAsStream(p_ressource);
if (file == null)
throw new FileNotFoundException("XSLT file not in DB");
byte[] buffer = new byte[4096];
int bytes_read;
while ((bytes_read = file.read(buffer)) != -1)
System.out.println(new String(buffer, 0 , buffer.length));
catch (Exception exp) {
System.out.println(exp);
Thanks

The code works as is. I just forgot to add the slash in front of the Resource file name.

How to get CPU status in Java program

Is there any way by which we can get CPU status in a java program ?
Whats the load on the cpu, whats the max it can handle ? and stuff like that.
Thanks in advance

It's not that there's "no way" to do it in Java, nor that native code is required. However, it's a non-portable solution. If you find a solution that works on Linux (e.g. read the cpu info from /proc), it probably won't work on any other OS. Typically, these problems are solved by:
1) Executing an external program and parsing the results
2) Finding the required information in /proc (not on Windows, though)
3) Writing some kind of JNI interface (again, OS-specific)

How to execute .msi files from java program

Hi friends,
i have written a java program which invokes and thereby execute any executable files like .exe and .bat.
So its working fine with .exe and .bat files, but it is not working with .msi files.......can you please help me how can i execute .msi files as well??
public class Executeexe {
     public static void main(String ar[])
          try
          Process p=null;
          Runtime rt=Runtime.getRuntime();
          p=rt.exec("D:\\mysql-essential-5.0.83-win32.msi");
          p.waitFor();
catch(Exception e)
}here is the program

Make sure that the command that's being exec'd works from the cmd line.
Then read this article and do what it says:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
Then if you still are having problems explain what "...it is not working with .msi files..." really means, and provide a [SSCCE Example program|http://mindprod.com/jgloss/sscce.html]

How to execute system command from java program

Hi all,
I want to change directory path and then execute bash and other unix commands from a java program. When I execute them separately, it's working. Even in different try-catch block it's working but when I try to incorporate both of them in same try-catch block, I am not able to execute the commands. The change directory command works but it won't show me the effects of the bash and other commands.
Suggestions??

The code I am using is....
try
String str="cd D:\\Test";
Process p=Runtime.getRuntime().exec("cmd /c cd
"+str);your str string is already having cd in it but again you ar giving cd as part of this command also please check this,i will suggest you to remove cd from str
Process p1=Runtime.getRuntime().exec("cmd /c mkdir
"+str+"\\test_folder");you should say mkdir once you change your path,but here you are saying mkdir first and then cd D:\Test(this is because of str)..please check this
Process p2=Runtime.getRuntime().exec("cmd /c bash");
Process p3=Runtime.getRuntime().exec("cmd /c echo
himanshu>name.txt");
catch(IOException e)
System.err.println("Error on exec() method");
e.printStackTrace();

How to get UCM content from Java class?

Hello,
I need to get UCM content from backend I mean from the Java class. Is there any way to do that? If anybody please give any resources it will be very helpful.
Thanks and regards.

Hi
You mean to say that with JAVA API you want to search and retrieve the contents ? If yes , then you should use RIDC API for the same and that way you can use to do all the operations on UCM from the JAVA Api .
Search this forum and you will get sample codes for the checkin , search , checkout operations .
Documentation is available at : http://docs.oracle.com/cd/E14571_01/doc.1111/e16819/toc.htm

How to call stored procedures from java program?

I have tried to run a program that calls a stored procedure on MySQL
server version 5.0.17 by using connector/j 5.0, but it always fails on the
statement: con.preparecall() ,
have looked on the internet and found out that people can all mysql
stored procedure all right in their programs, really dont know what's
wrong with this small peiece of code:
import java.sql.*;
public class TestDB {
      // procedure being called is:
     CREATE PROCEDURE `dbsaystorm`.`getsite` ()
     BEGIN
        select name from tblsite;
     END
     public static void main(String[] args) {
          try {
              //Class.forName("org.gjt.mm.mysql.Driver");
              Class.forName("com.mysql.jdbc.Driver");
              Connection con = DriverManager.getConnection("jdbc:mysql://localhost/dbname",
                        "user", "pwd");
       * executing SQL statement here gives perfect correct results:
        // PreparedStatement ps = con.prepareStatement("select name from tblsite");
        // ResultSet rs =ps.executeQuery();
              // but in stored procedure way...
              //it fails here on this prepare call statement:
              CallableStatement proc = con.prepareCall("call getsite()");
              ResultSet rs =proc.executeQuery();
              if (rs == null) return;
              while (rs.next()){
                  System.out.println("site name is: "+ rs.getString(1));
              rs.close();
          } catch (SQLException e) {e.printStackTrace();}
           catch (Exception e) {e.printStackTrace();}
}it always gives this exception:
java.lang.NullPointerException

     at saystorm.server.data.database.TestDB.main(TestDB.java:29)
where have I gone wrong?
when I commented out the statement that makes the procedure call and call preparedstatement to execute SQL select statement, it gave perfectly correct result.
it looks like there is no problem with java prog accessing MYSQL server database, but the it seems that it's just java can't call stored procedure stored on the mysql server version 5.
can it or can't it? if it can, how is that accomplished?

It is a bug in the driver because it shouldn't be
returning that exception (null pointer) even if you
are doing something wrong.
Are you using the latest version of the driver?
The stored procedure runs when you run it from the
gui/command line using a MySQL tool - correct?
As suggested you should be using the brackets. What
is the data type of the 'name' field?
You could try returning another value like one of the
following
select 1, name from tblsite;
select name, 1 from tblsite;
That might get around the bug
Additionally try just the following...
select 'test' from tblsite;yes, the driver used is in connector/j 5.0--the lastest one, and the
procedure can run correctedly at either command line or GUI mode
with no problem whatsoever, the returned data type is string type,
I have not got the chance to test it again with those values you
suggested, as I have abandoned the laptop I used to write that code
initately. There have been some other really weird cases happened on
that computer. I guess that must be something wrong with the JVM
installed on it, it was upgraded from jre5.0.04 to 06, and to 09.
something within hte JVM must have been messed up(the only reasonable
explanation). Because the same code runs correctly on my new laptop,
using the same environment: jvm 5.0_09, mysql 5.0.18, connector/J 5.0.
that old laptop really was a nightmare.
