Pass value from Java to Perl

Anyone knows how to pass value from Java to Perl program?

Did you write the perl program? Can you change it? Or are you trying to interface to something that already exists? This will limit your options, of course.
Anyway the first option is simple. The java program does this:
System.out.println("This is a line of input.");The perl program does this:
while(<>)and in that block, $_ is assigned to each line of input.
Then you can invoke both like this:
$ java MyJavaProgram | perl MyPerlProgram.pl

  • How to pass session from Java to Perl

    Hi,
    I need to pass a session value from Java to Perl, does anyone knows how can I do it?
    Thanks

    If you want to run java code from Perl, and have it return a single value, that's one thing: but having Perl interact with java code - calling methods, returning values - that may not be possible.
    Look into python to see if it may be what you're looking for. It's a scripting language that allows real interaction with java.
    If all you want to do is run java code and have it return some data, that would be trivial, so I assume that's not what you mean. But in case it is heres an idea:
    Set up a network connection between them with your own protocol, seeing as both languages are good at networking.

  • Java Thread - difficulty while passing value from parent to child thread

    Hi All,
    I am calling a java program from a unix script .
    My oblectives are
    1)to pass value from scripts to main java class
    2)main class should create a child thread and pass data to child and should return control back to script
    3)child thread should run independtly of parent
    The calling unix script is part of process and hence should return control back to its calling script immediately.
    Findings
    1)Without passing data thru setter getter /constructor method to child thread my objectives are met
    2)When I pass the data from parent thread to child thread calling unix scripts wait till child thread finishesh its working
    call.scr
    java Main <list of Arguments>
    Main.java
    public class Main
                 public static void main(String args[]) throws Exception
                 String data2="Z";
                 String data1=null;
                 for(int i=0;i<args.length;i++)
                      data2=data2+","+args;
    data1=data2;
    Child cu=new Child();
    cu.setData(data1);
    data2=null;
    data1=null;
    cu.start();
    Child.javaclass Child extends Thread
    public String data;
    void setData(String data)
    this.data=data;
    public void run()
    ----------> processing on data
    I think due to passing of data from parent thread to child thread (Inter thread data communication/Inter process communication)
      the threads are not working as desired.
    Plz anybody can suggest something.....

    aschin,
    You seem to be confusing Java Threads with Operating System Processes.
    If you want you're java program to run in the unix background then you'll need to run it in the unix background. Java (being o/s agnostistic) doesn't provide process manipulation functionality (which would include the ability to throw itself into the background, as a C program can) in the standard API, and it's hard to imagine any third party producing anything as low level as a process controler... so yeah, just start the java program in the background... and you'll need to workout some interprocess communication protocol... named pipes have worked well for me in the past, as they doesn't suffer from the quit same performance issues as real disk files.
    Good luck. Keith.

  • How to pass variable from Java to ABAP in BSPs

    Hello experts,
    taking into account the two environments (browser and server) I need to pass information from Java to ABAP.
    After seen this link: Re: View Refresh
    I have tried the next:
    HTMLB:  <input type="hidden" name="myFlag" value="">
    ABAP:   DATA: lv_height TYPE STRING.
    JAVA:   var intXo = readCookie("XEix");
    JAVA:   if ( intXo == 900 )                
    JAVA:   else if (intXo == 725 )            
    ABAP:   lv_height = request->get_form_field( 'myFlag' ).
    ABAP:   IF lv_height EQ 'X'.
    ABAP:     TRAYTAREAS_P = 'TRUE'.
    ABAP:   ELSE.
    ABAP:     TRAYTAREAS_P = 'FALSE'.
    ABAP:   ENDIF. 
    "document.all.myFlag.value" gets the correct value according the condition, but the ABAP code does not recover this value (lv_height is always initial).
    Can you help me with that? I'm not able to see where is the mistake...
    Exist any alternative way to recover in ABAP an JavaScrip value?
    thanks in advance.

    Hi Raja
    I think you are appointing to this posted solution:

    JAVA: var intXo = readCookie("XEix");
    JAVA: if ( intXo == 900 )

    ABAP: TRAYTAREAS_P = 'TRUE'.
    ABAP: ELSE.
    ABAP: TRAYTAREAS_P = 'FALSE'.
    ABAP: ENDIF.
    but it doesn't work. Can you detect if there is any evident error there or the process is right?

    put the values you want in the request attributes
    request.setAttribute("value1", value1);
    ...redirect to the jsp
    in the JSP:
    get the wanted attributes:
    String value1=(String)request.getAttribute("value1");To learn how to parse a xml file, pay a look at this page, it explains how to read the XML document to build an object representation, and then how to navigate through this object to get the data

  • Passing values from a FORM to another FORM

    Hi,
    I have to pass values from FORM "A" to FORM "B". What is the best way to do this?\
    Can I use a GLOBAL variable?
    Thanks,
    Marc.

    I think he meant the global namespace.
    You set a :global_your_name_here to a value and that value is available in your entire application. See the help file section on the global namespace for more information.
    Forms parameters are parameters that you form picks up from the outside when it starts. The calling entity must supply them in the URL or they will be set to null. You set them up in the object navigator in the Parameters node.

  • 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.

  • Passing parameters from java jdbc to pl/sql

    I’m calling stored procedures from java jdbc… but looking for nicer interfaces in terms of passing data. Has anyone come up with a good way to pass data from java jdbc to pl/sql without passing a million parameters? I’m thinking here of some type of structure like pl/sql rowtype or table index type or something else. Has anyone tried to create typed objects in oracle databases and access them from java?
    Thanks, Patrick Caldwell

    Hi Patrick,
    Yes, I have created an Oracle object type, which I successfully returned to a java class, from a PL/SQL stored function, using JDBC. Environment was J2SE 1.3.1, with Oracle 8.1.7.4 on SUN [sparc] Solaris 7 with Oracle's JDBC (thin) driver. It was a while ago, so I don't remember the details very clearly, but I recall being able to figure it out quite easily using the Oracle documentation and the sample code available at Oracle's Technet Web site.
    Hope this has helped you.
    Good Luck,
    Avi.

                 Í have a scenario where i need to pass value from Crystal Report to a Business view's parameter.
    Eg : CurrentCEUsername (func in crystal report)-- gives login user  which i should pass to parameter in a Business view (used in the same report).
    Will be able to explain more if required.
    Thanks in Advance,
    Bharath

    I guess you got the picture wrong.  User_id is not a report_level parameter .
    In Data Foundation, below query is used..
    select Acc_Number, Account_Group,User_id  from Accounts where user_id={?User_id}
    where in {?User_id}  is the BV parameter...
    The Filter was a solution. But it takes long time to Query all the data from DB and then filter at BV level.
    How do i pass the CurrentCEUsername to {?User_id}
    Value should ve CurrentCEusername always. so that query will be
    select Acc_Number, Account_Group,User_id  from Accounts where user_id=CurrentCEusername
    It will restrict the data pulled from DB to BV .. right?
