Invoking python program from java
I want to execute a parser program(which is in python) that parses log file from java interface.The design of Java user interface has to be such that the log file is obtained from the user into a text field.The file name has to be read from the text field and this has to be taken by the python log parser program.How can this be implemented?
You can invoke an external program using:
Runtime.getRuntime().exec("bla.exe");
See: http://java.sun.com/j2se/1.4.1/docs/api/

Invoke external programs from Java
I am running a Java program which will be used to invoke other command line programs in Windows.
However, it seems Java has problem in checking the termination state of command line programs in Windows. In the example below, the pp.waitFor() will keep waiting even if the command completed execution. I try the same code below in Unix and it works without problem. Is there anyone has come across the same problem before ?
I am using JDK1.4.1.
try {
Process pp = null;
BufferedInputStream bi = null;
pp=Runtime.getRuntime().exec("dir");
bi = new BufferedInputStream(pp.getInputStream());
pp.waitFor();
int size=bi.available();
while (size>0) {
byte[] buf = new byte[size];
bi.read(buf);
System.out.println(new String(buf));
size=bi.available();
} catch (Exception e) {
System.out.println("Exceptions !!!");
System.out.println(e.getMessage());I found this article rather helpful:

How do I call a C++ program from Java?
I've tried using Runtime.exec to call my C++ program from Java but I don't think I'm doing it correctly. Could someone explain how to properly use it? Here's what I'm trying (this is in an applet that is only going to be running on an intranet so only PCs in my LAN will be affected):
Runtime runtime=runtime.getRuntime();
Process proc =runtime.exec("mkdir C:\\Test");What do you expect your operating system should do with a command "mkdir"? It doesn't understand this. "mkdir" is a shell command, so you need to execute the shell:
runtime.exec("cmd /c mkdir C:\\test"); -
How to Call abap functn/program from java layer
Hi all,
I have to develop a program which has to call abap function/program from java side or how to call a abap program through java ..
pls send me related links or explanations.. dont send unrelated answers..
Regards,
Arivarasu SHi,
You mean accessing ABAP functions from J2EE perspective, then I think we can do this by using SAP Java Resource Adapter and also through webservices.
SAP Java Resource Adapter (SAP JRA) can be used as an add-on for the SAP JCo SAP JRA enables the implementation of standard interfaces from diverse J2EE servers to the SAP JCo in the SAP Web AS. The SAP JRA thus simplifies
communication with ABAP within heterogeneous J2EE landscapes.
Go through the following links which has Good documentation on how to achieve this
Accessing BAPIs Using the SAP Java Resource Adapter
[https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/ad09cd07-0a01-0010-93a9-933e247d3ba4]

Startrfc - SAP utility to invoke ABAP programs from External systems
We have used the startrfc uitlity that comes along with the SAP Presentation CD. This is bundled with the SAP RFC SDK kit. The startrfc utility can be used to invoke ABAP programs from external systems or servers.
When using the startrfc from the SAP server using the parameters
startrfc -h 10.60.0.31 -s 01 -c 100 -u USERNAME -p PASS -F <Function Module> -E TPPARAM=\usr\sap\trans\bin\tp_domain_<SID>.PFL -T LIST,300,w=list.txt
the desired results are achieved.
However when using the same startrfc with the exact parameters from another server we get the message " Incorrect user or password". If we use the SAP GUI from this server to connect to the SAP server using the same username and password we are able to connect to the SAP system.
Has anyone encountered any similar issues with Startrfc? Any suggestion will be appreciated.
Thanks,
~NileshHi NIlesh,
Did you check that the password and user ID entered are in capita letters?
Thanks and Regards,

Error in calling 'C' Program from Java
Hi,
We developed a 'C' Program and during compilation, we got a couple of Incompatible Prototype warnings. Then we made a Jni call to 'C' program from Java Program. The program returned a "Unsatisfied Link Error - unreference Symbol not found" error.
Does Jni call fails owing to warnings by compiler?
We are using Sun Solaris 2.8.
Request your assistance as this a urgent issue.
Thanks
SriniDid you try running your C program through g++? It sounds like something is broken, but GCC often will allow you to compile anyways.

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?
ThanksLook 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? -
