Hey all,
Trying to get into this new fangled "Java" thingy in 8.1.7.2.0 on HP/UX.
Simple OS exec test, mostly plagarized:
// qlp.java
import java.lang.Runtime;
import java.lang.Process;
import java.io.IOException;
import java.lang.InterruptedException;
public class qlp {
public static int main(String args) {
int retval = 0;
try {
String lpCommand;
lpCommand = "/usr/bin/lp " + args;
Process p = Runtime.getRuntime().exec(lpCommand);
try {
p.waitFor();
} catch (InterruptedException intexc) {
System.out.println("Interrupted Exception on waitFor: " +
intexc.getMessage());
}
retval = p.exitValue();
} catch (IOException e) {
e.printStackTrace();
}
return (retval);
}
}
// End of Java code
I run javac to compile it, then loadjava the class file into the DB. I can
then create a PL/SQL procedure as a wrapper:
CREATE OR REPLACE PROCEDURE qlp_proc (file_and_parms IN VARCHAR2)
AS LANGUAGE JAVA
NAME 'qlp.main (java.lang.String[])';
/
And it works, but I need to test for success/fail. But if I try a FUNCTION
wrapper:
CREATE OR REPLACE FUNCTION qlp_func (file_and_parms IN VARCHAR2) RETURN
NUMBER
AS LANGUAGE JAVA
NAME 'qlp.main (java.lang.String[]) return int';
/
I get PLS-00311: the declaration of "qlp.main (java.lang.String[]) return
int" is incomplete or malformed.
Two questions: 1) Every example I've seen of the wrapper excludes the
brackets from the java.lang.String parameter def, but I can't get a compile
without it. Why? And 2) Anyone know what's wrong with my FUNCTION def?
Desperately needing a good Java tutorial, too!
TIA!
