How to execute .jar file in c#

Javier Sanchez

Hi everybody, im trying to execute a .jar file in my c# program, i have try several times and get examples, but i can't do it.

I execute in the cmd, like this
java -Xms60m -Xmx256m -jar C:\\Programming\\Interface.jar";
and this open the program.

But, trying with the Process class:

Process process = new Process();
System.Diagnostics.ProcessStartInfo procInfo =
new System.Diagnostics.ProcessStartInfo("java -Xms60m -Xmx256m -jar C:\\Programming\\Interface.jar");

process = System.Diagnostics.Process.Start(procInfo);

and other instructions, i get an exception, the file can't be found.

Some one knows??
Thanks in advance.

Make Sure you have added your Java/Bin Directory to System's Path variable

            string filename = "jar File Path Here";
            Process p = new Process();
            p.StartInfo.FileName = "java.exe";
            p.StartInfo.Arguments = "-jar "+filename ;
            p.Start();

When starting an application with command line arguments, the ProcessStartInfo needs to be constructed with the arguments as the second parameter.

For example, use

new System.Diagnostics.ProcessStartInfo(@"C:\Program Files\Java\jdk1.6.0_14\bin\java", "-Xms60m -Xmx256m -jar MyJar.jar")

Note also that the full path to the java executable is required where the java executable is not in the path.
