QuestionStart java program from Objective C code Pin
DraqueD5-Jan-15 8:42
MemberDraqueD5-Jan-15 8:42 
I'm trying to make a pretty simple frontend program that's able to start up a java program when it's run, but haven't yet mastered OC. Someone suggested that I try using a console command (code below), but I haven't been able to make that work yet.

Is there an easier way to do this, or does any one here know where my code has gone wrong?

C#
int main(int argc, const char * argv[]) {

    NSFileManager *filemgr;
    NSString *currentpath;

    filemgr = [[NSFileManager alloc] init];

    currentpath = [filemgr currentDirectoryPath];

    NSPipe *pipe = [NSPipe pipe];
    NSFileHandle *file = pipe.fileHandleForReading;

    NSTask *task = [[NSTask alloc] init];
    task.launchPath = [currentpath stringByAppendingString:@"/java"];
    task.arguments = @[@"-jar", @"PolyGlot.jar"], [NSString stringWithFormat:@"%c", argv]];
    task.standardOutput = pipe;

    [task launch];

    NSData *data = [file readDataToEndOfFile];
    [file closeFile];

    NSString *grepOutput = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
    NSLog (@"grep returned:\n%@", grepOutput);

    return 0;
}


When I run this, I get the error:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'launch path not accessible'

I know that the current path is accessible, though... so I'm kind of stumped here. Any help would be much appreciated. Thanks!
