在服务器中使用bat文件运行jar

Question

I have a application hosted in server. I have a bat file which will run a .jar file. The jar is running when i double click on bat/jar. But when a integrated it in my application and tried to run the jar, it is not executing.

Here is the code for running bat file :

<%
 Runtime.getRuntime().exec("c:\\windows\\system32\\cmd.exe /c D:\\Create_Confluence.bat");
%>

This code runs, because when we tried creating a folder the cmd runs & creates the folder.

Here is the code inside bat file for running the .jar:

"C:\Program Files (x86)\Java\jdk1.7.0_15\bin\java" -jar D:\confluence.jar "D:\\Eclipse\\Fourprojects\\Excel\\Space.xls" 
pause

But the jar file is not getting executed.

Can somebody help me with this...

Answer 1

You have to provide working directory as like below .

Runtime.getRuntime().exec("c:\\windows\\system32\\cmd.exe /c Create_Confluence.bat", null,"D:\\"); 

Check this method here in this link

public Process exec(String command,
                    String[] envp,
                    File dir)
             throws IOException

*Parameters:

command - a specified system command.

envp - array of strings, each element of which has environment variable settings in the format name=value, or null if the subprocess should inherit the environment of the current process.

dir - the working directory of the subprocess, or null if the subprocess should inherit the working directory of the current process.*
