How to run jar file form C# code

Question

I am new to C# and tying to run jar file from C# code. But it seems that jar file is not opening and command prompt disappers very quicky as I am unable to see any error messgage.

Here is my code ,

myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.FileName = "java";
myProcess.StartInfo.Arguments = "D:\\DATA\\PROJECT\\LicensingManagement\\Assignment\\JavaLogin.jar";
myProcess.Start();

Can any one put me in right direction ? Whats wrong I am doing here ?

Your code is fine, your java command is not. To run a jar, you need to run: `java -jar .jar` — CodingIntrigue, May 20 '14 at 07:13
This looks almost duplicate http://stackoverflow.com/questions/4427371/run-jar-file-from-c-sharp?rq=1 , but it deals with path to the `java` executable... You still may be interested in it as it shows complete correct code. — Alexei Levenkov, May 20 '14 at 07:16
@AlexeiLevenkov And `D:\\DATA` may not exist. But hey, I can't fix all the worlds problems - just the obvious ones ;) — CodingIntrigue, May 20 '14 at 07:17

You will have to provide -jar switch to java command.

For example, the command to execute JAR file is,

java -jar D:\\DATA\\PROJECT\\LicensingManagement\\Assignment\\JavaLogin.jar

So you may try,

myProcess.StartInfo.Arguments = "-jar D:\\DATA\\PROJECT\\LicensingManagement\\Assignment\\JavaLogin.jar";

thanks it's working. But it seems that command prompt is also opening with jar file , is there any way to open jar file without opening command prompt. – Planet-Zoom May 20 '14 at 07:18
@user3556028 Please don't ask follow-up questions in the comments. Open another question. – CodingIntrigue May 20 '14 at 07:20

@user3556028 use `javaw` to run without the console – Nick Holt May 20 '14 at 09:02
Doesn't it work, "myProcess.StartInfo.CreateNoWindow = true" ? – Pritesh Gohil Dec 14 '21 at 10:52
