I'm trying to trigger java command line application as a sub process from golang. For some reason it failed and actually I do not get java APP interface when I start it from GO. It wait for few sec and terminate with error code "can not connect ... " Here is a code I tried to use:
package main
import (
"fmt"
"os/exec"
)
func main() {
start_java_app_test()
}
func start_java_app_test() {
cmd_prep := "java -Xmx2g -jar test_app.jar"
cmd_output, err := exec.Command("bash", "-c", cmd_prep).Output()
if err != nil {
fmt.Println(err)
}
fmt.Println(vba_ssh_cmd_output)
}
If we try just to use --> cmd_prep := "java -version"
<--
it will fail again.
It should give me output like
<< snip >>
$ java -version
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)
<< /snip >>
The normal syntax like --> cmd_prep := "ls -l"
<-- works fine.
Any clue ?
What might be the reason here ?
Thanks in advance,
