  • 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.

  • Starting exetutable java file from java code

    Hi I was wondering how I can start a executable java file from java code?
    thanks

    Hi Mkaveli,
    Yes, it's possible. If you have a JAR executable, you've just to call the main method of its starter class. For a simple executable class, just call its main method.
    This way :
    SomeStarter.main(null); // if there's no argumentSmall precision : the executable JAR or class must be specified in the classpath of your application.

  • How to modify an existing xml file from java code.

    Hi
    I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
    For example if xml file(studlist.xml) is as below:
    <?xml version="1.0" encoding="UTF-8"?>
    <StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
         <Student>
              <Name>ram</Name>
              <Age>27</Age>
         </Student>
    <Student>
              <Name>sham</Name>
              <Age>26</Age>
         </Student>
    </StudentList>
    Now suppose i have set name to victor using student.setName,
    and set age to 20 using setAge from javacode,
    the new xml file is as follows:
    <?xml version="1.0" encoding="UTF-8"?>
    <StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">

    <Student>
              <Name>sham</Name>
              <Age>26</Age>
         </Student>
    </StudentList>
    <Student>
              <Name>victor</Name>
              <Age>20</Age>
         </Student>
    As observed this is not a valid xml file.But how can i modify without any errors?

    I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
    Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
    What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
    // gets the root element of the specified file (code not shown)
    Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
    // write a new student element
    Element student = document.createElement("Student");  // creates the new student
    rootElement.appendChild(student); // ***appends it to the root element***
    Element name = document.createElement("Name"); // creates the name element
    name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
    student.appendChild(name); // appends the name to the student
    Element age= document.createElement("Age"); // creates the age element
    age.appendChild(document.createTextNode("26")); // adds the age text to the age element
    student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file

    Hi All,
    Can any one provide me the exe file name of SAP GUI related.
    I need to call the SAP GUI related exe file from java.
    i tried with a small java prog which executes the exe files.
    it works fine with notepad.exe,javac.exe . But i am unable to execute the SAPgui.exe.
    This is my java code
    try{
         Runtime rt=Runtime.getRuntime();
    //String str= "C:
    WINNT
    system32
    notepad.exe";
    //Process pp=rt.exec("C:

    BufferedReader br=new BufferedReader(new InputStreamReader(pp.getErrorStream()));
                         String line;
                         while ((line = br.readLine()) != null) {
                             System.out.println(line);
              }catch(Exception e){
                   System.out.println(e);
    and may i pass any additional parameters inorder to invoke this exe.
    Please share your ideas abt  this problem.
    Its Urgent PLZ

    hi Rajesh,
    here my complete code:
              try{
                   Runtime rt=Runtime.getRuntime();
    //               String str= "C:\Programmi\SAP\FrontEnd\SAPgui\saplogon.exe";
                   String str= "C:\Programmi\SAP\FrontEnd\SAPgui\Sapgui.exe 10.113.10.201 00";
                   //               Process pp=rt.exec("C:\j2sdk1.4.2_08\bin\javac");
                   Process pp=rt.exec(str);
                   BufferedReader br=new BufferedReader(new InputStreamReader(pp.getErrorStream()));
                   String line;
                   while ((line = br.readLine()) != null) {
                   System.out.println(line);
                   }catch(Exception e){
                   System.out.println(e);
    Please note that system number is only two digit and in your case is 00.
    Another important think, i'm using the italian version of windows, so the program directory is c:\programmi, please change into c:\program files, or you can modify your code to be language indipendend using an system environment variable (if exist).
    Hope this help

  • How to pass arguments to a batch file from java code

    Hi
    I have a batch file (marcxml.bat) which has the following excerpt :
    @echo off
    if x==%1x goto howto
    java -cp C:\Downloads\Marcxml\marc4j.jar; C:\Downloads\Marcxml\marcxml.jar; %1 %2 %3
    goto end
    I'm calling this batch file from a java code with the following line of code:
    Process p = Runtime.getRuntime().exec("cmd /c start C:/Downloads/Marcxml/marcxml.bat");
    so ,that invokes the batch file.Till that point its ok.
    since the batch file accpets arguments(%1 %2 %3) how do i pass those arguments to the batch file from my code ...???
    %1 is a classname : for ex: gov.loc.marcxml.MARC21slim2MARC
    %2 is the name of the input file for ex : C:/Downloads/Marcxml/source.xml
    %3 is the name of the output file for ex: C:/Downloads/Marcxml/target.mrc
    could someone help me...
    if i include these parameters too along with the above line of code i.e
    Process p = Runtime.getRuntime().exec("cmd /c start C:/Downloads/Marcxml/marcxml.bat gov.loc.marcxml.MARC21slim2MARC C:\\Downloads\\Marcxml\\source.xml C:\\Downloads\\Marcxml\\target.mrc") ;
    I get the following error :
    Exception in thread main java.lang.Noclassdef foundError: c:Downloads\marcxml\source/xml
    could some one tell me if i'm doing the right way in passing the arguments to the batch file if not what is the right way??

    1 - create a java class (Executer.java) for example:
    import java.lang.reflect.InvocationTargetException;
    import java.lang.reflect.Method;
    public class Executer {
         public static void main(String[] args) {
              try {
                   for (int i = 0; i < args.length; i++) {
                        System.out.println(args);
                   Class<?> c = Class.forName(args[0]);
                   Class[] argTypes = new Class[] { String[].class };
                   Method main = c.getDeclaredMethod("main", argTypes);
                   // String[] mainArgs = Arrays.copyOfRange(args, 1, args.length); //JDK 6
                   //jdk <6
                   String[] mainArgs = new String[args.length - 1];
                   for (int i = 0; i < mainArgs.length; i++) {
                        mainArgs[i] = args[i + 1];
                   main.invoke(null, (Object) mainArgs);
                   // production code should handle these exceptions more gracefully
              } catch (ClassNotFoundException x) {
                   x.printStackTrace();
              } catch (NoSuchMethodException x) {
                   x.printStackTrace();
              } catch (IllegalAccessException x) {
                   x.printStackTrace();
              } catch (InvocationTargetException x) {
                   x.printStackTrace();
              } catch (Exception e) {
                   e.printStackTrace();
    2 - create a .bat file:
    @echo off
    java -cp C:\Downloads\Marcxml\marc4j.jar; C:\Downloads\Marcxml\marcxml.jar; Executer %TARGET_CLASS% %IN_FILE% %OUT_FILE%3 - use set command to pass variable:
    Open MS-DOS, and type the following:
    set TARGET_CLASS=MyTargetClass
    set IN_FILE=in.txt
    set OUT_FILE=out.txt
    Then run your .bat file (in the same ms dos window)
    Hope that Helps

  • Running a jar file from java code

    Hi!
    Im trying to run a jar file from my code.
    I've tried Classloader, but that doesnt work because it doesnt find the images (also embedded in the 2nd jar file).
    WHat I would like to do is actually RUN the 2nd jar file from the first jar file. There must be a way to do this right?
    any ideas?

    ok, I found some wonderful code (see below) that will try to start the jar. But it doesn't. What it does is produce the following error when my application runs...
    So it's not finding the images in the jar file that I am trying to run? Strange. I checked the URL that sending, but it seems ok....
    I think I will check the url again to make sure......
    any ideas?

  • Write HTML Files from java application

    Hello,
    i have to write HTML files from a java application.
    I am asking if anybody can give me a hint about a good simple solution (library) which can do some of the job for me.
    i know FOP for example is good to create pdf or html from xml, but i dont want to go via xml.
    the sites i need are really very simple presents emails.
    body and maybe a link for next and pervious.
    however, thank you in advance.
    a little hint will also help :)
    Sako.

    That, too, is my question.
    Be the "server" local or remote, wouldn't JSPs still
    be the easier solution? No. it will not. because you need a server. Server for a stand alone application is not esier. according to who said JSPs are easy?
    Its very very difficult.
    >
    When answering, please clarify. I'm a bit of a newbie
    here. :)To get sence about how hard is JSP, check Struts. this is very good open source Framework to simplify the JSPs. but it still complecated enough.
    or Tapestry my lovely open srouce Framework.
    its easier than Struts. but sill complecated because of the documentation.
    All in all, using JSP is the purpose of Java in the internet. but not for me. My application will not be available in the internet, i.e. no server, i.e. no need for JSP.
    i hope that helps a little.

  • Executing a .bat file from java code

    Im writing a utility and i need to be able to create and execute a .bat file from my program. I can create the .bat file fine but when i try to execute it nothing happens. I tried to use the following line of code to try to execute the .bat file (called make.bat) :
    try
    String parameterString = "\"C:\\WINNT\\System32\\cmd.exe\" C:\\ITS_Test\\make.bat";
    Runtime.getRuntime().exec(parameterString);
    catch (Exception e)
    System.out.println(e);
    The Runtime.getRuntime()exec() method worked fine when trying to execute an excel file but for some reason it dosen't want to work for the DOS prompt. Any ideas?

    Thanks everyone for all the replies.
    I have tried all the above with no luck. Im using netbeans, does anyone think that it could be a problem with the IDE.
    I tired the following code :
    String parameterString = "cmd.exe /C \"C:\\ITS_Test\\make.bat\"";
    Process pr = Runtime.getRuntime().exec(parameterString);
    pr.waitFor();
    This code does not throw any exceptions but just hangs. I also tried:
    String [] parameterString = {"cmd", "/c", "C:\\ITS_Test\\make.bat"};
    Process pr = Runtime.getRuntime().exec(parameterString);
    pr.waitFor();
    and:
    String parameterString = "\"C:\\WINNT\\System32\\cmd.exe\" \"C:\\ITS_Test\\make.bat\"";
    Process pr = Runtime.getRuntime().exec(parameterString);
    pr.waitFor();
    with the same result. Does anyone know why it just hangs and nothing happens (no exceptions thrown)?
