Batch files from JSP

Hi,

This is not entirely a struts question, but how would I execute a batch from
on the server from a jsp?

If the .bat is in the same file as the jsp calling it.


I tried

    Runtime rt = Runtime.getRuntime();

    Process pr= rt.exec("db.bat");

But it gives errors.

java.io.IOException: CreateProcess: db.bat error=2
	java.lang.ProcessImpl.create(Native Method)
	java.lang.ProcessImpl.<init>(ProcessImpl.java:81)
	java.lang.ProcessImpl.start(ProcessImpl.java:30)
	java.lang.ProcessBuilder.start(ProcessBuilder.java:451)
	java.lang.Runtime.exec(Runtime.java:591)
	java.lang.Runtime.exec(Runtime.java:429)
	java.lang.Runtime.exec(Runtime.java:326)
	org.apache.jsp.batch_jsp._jspService(batch_jsp.java:59)
	org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
	org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:332)
	org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)
	org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:802)


Any help would be great,

Thanks,

Akshay

My advice would be to be more specific in the command you shell out with 
and directly call the perl executable.

Something like: Process pr= rt.exec("c:\\Path_to_perl\\perl.exe 
c:\\Program Files\\Apache Software Foundation\\Tomcat
5.5\\webapps\\sheet\\batch\\db.PL");

Re: Batch files from JSP

Thanks for that...

I went over that document and a few others on Google...the batch file is
still not working out.

Instead of a batch file if I try and execute a perl script (.PL) located on
the host from a remote computer ...

Process pr= rt.exec("c:\\Program Files\\Apache Software Foundation\\Tomcat
5.5\\webapps\\sheet\\batch\\db.PL");

I get an error=193 error. Based on research, that error means that it cannot
find the program with which to open the file. I have set the environment
variables PATH to the perl bin, as well as added .PL in PATHTEXT.

Any ideas what else I would need?

Thanks,

Akshay
