Invoke perl script from JAVA 1.4.2

Hello All,

Has this been resolved?
I'm having an issue with it also, using the command line as such:
j2sdk-1_4_2_02-windows-i586-p.exe /s /v "/qn ADDLOCAL=jrecore IEXPLORER=0 INSTALLDIR=D:\Progra~1\j2sdk-1_4_2_02 REBOOT=Suppress JAVAUPDATE=0 /L D:\temp\jvm142install.log"
I've also tried different variations of the commands in "", but still no luck.
From the command prompt it appears to hang, but comes back to the command prompt about 10 seconds later and nothing gets installed.
Previous to installing it from the command line, I had installed it manually, and ran add/remove programs to remove it from the system.
Is there something I should check in the registry that might be prevening the above command to run?
InstallSheild's web site was helpful, but gave command line options for the msiexec to run.
Any help would be appreciated!

Call PERL script from JAVA

I am facing a problem in running a PERL script in JAVA in UNIX box..
I am able to call ther perlscript.
Perl script has
#! /usr/local/bin/perl
print "\nEnter Your Name :";
$name = <>;
print "\nYour Name is : $name\n";
exit 0;
Perl script request for the INPUT(name) .
My Java program is
File perlfile = new File("test.pl");
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("perl "+perlfile);
Here is the problem tat IT IS says error =2 ..What has to be the solution so tat i can CALL PERL SCRIPT as similiar to running it separatly in prompt { >perl test.pl }
PLEASE help me on this....

In the PERL SCRIPT (test.pl)
LINE 1 : #! /usr/local/bin/perl
LINE 2 : print "\nEnter Your Name :"; .
LINE 3 : $name = <>;
LINE 4 : print "\nYour Name is : $name\n";
LINE 5 : exit 0;
When i run this script in perl test.pl in prompt (UNIX BOX), i am gettin the request for name "Enter Your Name:____ " but when i call this script from Java it doesn't request for name and moreover the process doesnt ends (use ctrl+c to come out of the process).When i come out forcefully it shows the ERROR=2.
My requirement is such tat need to call a PERL SCRIPT from java so tat java process give the control to PERL script and it will continue the process..
Sample scenario:
Java move a file and store it in a new FOLDER
MY perl script will read the file in new FOLDER.
here the perl script will get the file name for processing... My issue comes here .$name is not be prompted while calling thro java..

How to run the perl script from java ?

Hi , I need to run the pearl script from the server and to get the result of the script thro' java using SSH
Is there any 3rd party SSH API in java ?
Please help me out
thanks in advance

This seems like a very strange thing to want to do.
What is the perl script doing?
Do other programs (not some shell script) access this server-side perl script from a different machine?
If so how do they do it?
What currently triggers the perl script to execute?
What currently handles the output from the perl script?
If you can answer these questions (and understand the answers) you should be able to come up with a different approach to this.
You do not really want to call a remote perl script from a Java program, you want to achieve the effect you think that would have if you could do it.
So find the answers to the above questions, write them on 3" x 5" cards and lay them out on your desk.
What flow of control needs to happen? Which piece of code needs to produce or consume which piece of data?
If that fails, ask you self or who ever is making you do this what are the use-cases?
If you do not know what use-cases are or do not understand them well enough try reading
Use Case Modeling (The Addison-Wesley Object Technology Series) by Kurt Bittner and Ian Spence (Paperback - Aug 30, 2002)

It is a short and easy to read book on the subject and also one of the best.
You MUST understand WHAT you are trying to achieve before you can decide HOW you are going to achieve it.

Invoking Shell Script from JAVA Stored procedure

As and alternative you can useString cmd123 = "perl /home/deaddev/test1.pl";Using the single string approach YOU have to do any quoting so with this line no quoting takes place and the script /home/deaddev/test1.pl will be executed.Although that should be true apparently it isn't. I have just run
Process p = Runtime.getRuntime().exec("perl /home/sabre/work/dev/perl/xxx.pl");
new Thread(new SyncPipe(p.getErrorStream(), System.err)).start();
new SyncPipe(p.getInputStream(), System.out).run();
int returnCode = p.waitFor();
System.out.println("Return code = " + returnCode);which correctly executes the perl script xxx.pl.
P.S. SyncPipe is a Runnable that copies an InputStream to an OutputStream.

Interesting! Even though Runtime.exec() works with a single String, ProcessBuilder fails with this approach! You have to split the argument string. This certainly looks like a bug! Some while ago I looked at the source for Runtime.exec() to look at the differences between Runtime.exec() and ProcessBuilder and found that behind the scenes Runtime.exec() uses ProcessBuilder.
More research is required.

Invoking a bash shell script from Java code

Hi All
I am trying to invoke a Bash shell script using java code. The arguments required are "source wmGenPatch <source dir> <destination dir> no_reverse.
in the code I have specified the arguments considering the cannonical paths of the files as the code may run on Unix or windows platform.
I am getting a error while invoking Runtime.getRuntime().exec(args). The error is as follows :
"The Error Occurred is: CreateProcess: source D:\Package4.0\workspace\DiffEngineScripts\v4a02\wmGenPatch D:\Package4.0\workspace\fromImageFilesDir\ D:\Package4.0\workspace\toImageFilesDir\ no_reverse error=2"
It seems that error=2 indicates that the 'file not found' exception. But i can see the directories referred to in the error at place in the workspace.
Kindly advice.
Thanks in advance.

Hi All
I am pretty new to invoking bash shell scripts from java and not sure if i am progressing in right direction.

          } else {
               separator = "\\";
          String args[] = new String[7];
          args[0] = "/bin/sh";
          args[1] = "-c";
          args[2] = "source";
          args[3] = currentDir + separator + "DiffEngineScripts" + separator
                    + "v4a02" + separator + "wmGenPatch";
          args[4] = sourceFileAdd;
          args[5] = destFileAdd;
          if (isReverseDeltaRequired) {
               args[6] = "reverse";
          } else {
               args[6] = "no_reverse";
          try {

               InputStream result = xyz.getInputStream();
               InputStreamReader isr = new InputStreamReader(result);
               BufferedReader br = new BufferedReader(isr);
               String line = null;
               while ( (line = br.readLine()) != null)

Executing a perl script from within java application

Hi,
Does anyone knows a way to execute a perl script from within java.

Of course whether that "works" depends on what the script does and where the java program runs.

At Craig's suggestion: Why Invoke PERL functionality from WD-ABAP?

Craig -
This is response to your suggestion that I post my own reasons for thinking that it would be useful to be able to invoke PERL functionality from WD-ABAP.
Please note at the outset that these reasons are based on my own personal belief that the relatively new vertical sectors of bioinformatics/biomed could produce reasonably significant income for SAP in a reasonably short time if SAP decided to create application-level functionalities in these areas.
This belief is in turn based on a very significant new initiative which has been publicly announced by the university Medical Center recently voted "most-wired" (Vanderbilt) and equivalent initiatives at other university Medical Centers across the country. (BTW, I've posted a meeting time (Tue 7pm) at Tech Ed for anyone who wants to learn more about these initiatives, the new vertical sectors they define, and how SAP could EASILY play in them.)
So, with this background established, assume that SAP does decide to play in the bioinformatic/biomed sector.
SAP will rapidly find that a lot of biomed is based on the kind of bioinformatics that essentially does pattern-analysis on two kinds of strings: polynucleotide strings (DNA, mRNA, tRNA, etc.) and polypeptide strings (mainly the amino acid strings that form the "primary structures" of protiens.) For example, biomed will soon include the ID of "at risk" markers for all patients in a university medical center, indicating what diseases patients may be genetically at risk for due to SNP's and other abnormalities in their inherited DNA.
Now when such analysis is not done by running "canned" versions of well-developed programs such as the ubiqitious BLAST program for "aligning" polynucleotide or polypeptide sequences, it is done by programs written in languages that offer superb capabilities for pattern-searching and manipulation of strings, e.g. PERL.
Additionally, I know from personal experience and the experience of my SigOther that even data obtained from well-known canned programs must be further massaged by non-canned techniques that again are readily implementable in PERL and other similar languages.
Finally, a lot of bioinformatic/biomed applications require iterative batch execution of canned stat routines such as t-tests or normality tests, which can be conveniently done via calls from languages such as PERL to canned products such as STATA.
So assume SAP wants to develop a biomed application that has:
back-end data containing the usual kinds of info med centers need to know about patients, plus the new kinds of scientific info about patients that med centers are creating
a presentation component that displays these two kinds of data for query, further elaboration/refinement, and subsquent update.
For example, there will be times when a doctor will want to take scientific data on a patient from the back-end (e.g. portions of a patient's DNA), subject it to pattern-analysis of the type described above, and then store the results of the analysis as additional new scientific info in the back-end databases.
And SAP can readily provide the doctor with this capability if it allows PERL functionality to be invoked from WD/WD-ABAP components. In some cases, the PERL will simply invoke industry-standard canned programs such as BLAST and wrap the results in a way friendly to SAP. In other cases, the PERL may do the analysis itself. In other cases, the PERL may invoke stat programs. Etc, etc. etc.
The point is that there is a vast inventory of bioinformatic/biomed PERL code out there, and if SAP wants to get serious about playing in the bioinformatics/biomed sector, it will be much easier to talk to this inventory of programs rather than recreate it in JAVA or SAP inside SAP.
Anyway, please remember - this post was based on the assumption that SAP may want to get serious about playing in the bioinformatic/biomed sector.
If not, then as Rosanne Rosanadanna used to say, "Never mind".

Hi David,
Where it can be used :-
Anywhere that you can insert ABAP code to run, you can integrate Perl in the manor that I laid out. The only requirements are the ability to run registered RFC programs, and to execute ABAP code including RFC calls (which is anywhere inside of an R/3 system basically).
Comparison with other techniques :-
All communication from the ABAP stack with the J2EE stack is done via RFC - this is only faster than a registerd RFC Server if Fast RFC is used which means that the J2EE stack MUST reside on the same host as the R/3 instance. Therefore there is no performance difference at that level and any performance differentiation is going to be in the programming language Perl vs Java, or payload encoding techniques (XML) at that level (not withstanding the consideration of development time).
There is also the HTTP Client communication facilities - with or without document encodings (the ICF + eg. SOAP). Again - I'd take a long hard look at whether it is necessary to be encumbered with the data packet encoding/ecapsulation overhead.
What you gain :-
Once you are in the "land of Perl" you have access to essentially any module you can find on CPAN, so any data access you require whether it be some kind of application server technology, or DB, can be fullfilled by whats available there (unless you need to roll your own?). And lets not forget algorythm implemented in Perl or Perl XS extensions - probably very important in the medical/scientifc field.
SOA (IMO) is a big ugly 4 letter word. At the end of the day, you have to look where your time and money is best spent, and whether you can achieve the desired results using Scripting Language Connector technology, or whether you feel compelled to go down a WS-* style route.
However - I would like to say this - IMO it is totally unecessary to wrap up system integration in multiple (expensive both in money, and performance considerations) layers if you are confident that you have good control over both ends of the communication streams. I believe that when your main objective is to utilise large chunks of code written in another language (rather than reimplement it in something closer to SAPs core interests), or communicate with inhouse data sources/systems (I've done this for MySQL before), then this is definitely one such case that opens the door for using my outlined approach (in the article).
Cheers,
Piers Harding.

Invoke beanshell methods from java

Hello
I'm learning beanshell and using it to write scripts that are ran in JDK 6.
My question is how to invok beanshell methods from java source codes.
My codes is:
import javax.script.*;
public class InvokeFunctions {
public static void main (String[] args)throws ScriptException, NoSuchMethodException
ScriptEngineManager sem = new ScriptEngineManager();
ScriptEngine bshEngine = sem.getEngineByName("beanshell");
String script = "public void sayHello()"+"{print (\"sayHello() is a method in bsh script\");}";
bshEngine.eval(script);
Invocable inbshEngine = (Invocable)bshEngine;
inbshEngine.invokeFunction("sayHello");
I defined a method "sayHello()" using beanshell, but i just can't invoke it in Java.
I got an error msg said:
Exception in thread "main" java.lang.IllegalAccessError: tried to access method bsh.NameSpace.getThis(Lbsh/Interpreter;)Lbsh/This; from class bsh.engine.BshScriptEngine
Any one has any idea about it?
Thanks

Look at the Javadoc documentation of IllegalAccessError. It says:
Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to.
Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.
Maybe recompiling all your sources (make sure you delete all existing *.class files) will help?

Hi,
Thanks for the reply from everyone.
The attached is my code to call Perl script and after calling this, I need to query the Perl Script by sending command like @help. Do they have a way to query the Perl script by sending command like @help and get the return result.
I think Joseph you are right, but how do I get the return result if I invoke it in a separate dos session.
