<h2>Hello, all</h2>
<p>I `ve heard rumors that Perl can be glued to other programming languages such as C++. I am interested how can this be done in Java, so I can use some tools from Perl I can`t normally use from Java, also, can I pack it into the jar file, so, let`s say, I can use a java program with Perl bindings on Android device? </p>
<p>I`d really appreciate some small examples and explanations.</p>
<p><b>Edit</b></p>
<p>Here is an example in Java with it`s defaults scripting engine(JS).</p>
<code>
import javax.script.*;
import java.io.*;
class Jsc {
public static void main(String[] args) {
try {
ScriptEngine engine =
new ScriptEngineManager().getEngineByName("javascript");
for ( String arg : args ) {
FileReader fr = new FileReader(arg);
engine.eval(fr);
}
} catch (IOException ioEX) {
ioEX.printStackTrace();
} catch (ScriptException scrEX) {
scrEX.printStackTrace();
}
} //end of main
} //end of class
</code>
<p><b>Updated</b> Passing a .js script file will result in executing it, also the js can interact with the program if programmed. Perl has Java modules from CPan, in Java cookbook by F.Darwin there is a topic: "Marrying Perl and Java" which gives a partial answer to my desire, but - it`s going from Perl, I need something as above code but with perls scripts so like I can program my java app with a small perl scirpt, let`s say perl script will search for files, java will read and execute them.(Just example, I won`t do exactly this). </p>
<p>I wonder if it can be done with Perl? </p>
