Thanks for the help Avi.

Upon further googling I found the following solution
Process proc=Runtime.getRuntime().exec(new String[]{"sh","-c","ps -ef | grep /home/abcd"}));

I am a beginner to unix so i apologize for the ignorance. However the input is coming from a form in a web application and not command line. Would that make any difference?

Thansk for your reply Avi.
In the command i want to run "ps -ef | grep /home/abcd" the "home/abcd" part is not known beforehand. I am getting that as an input and creating the command runtime so i dont think making a shell script would be possible. Is there any other way?

Thanks

Hi,

How do i run commands which contain piping(|). I believe that being a shell feature it wont be recognized by java.

What i am trying to do is something like :
Process proc=Runtime.getRuntime().exec("ps -ef | grep /home/abcd"); BufferedReader reader=new BufferedReader(new InputStreamReader(proc.getInputStream()));
the output i get returns all the processes and doesn't seem to go beyond the piping.

Is there any solution to this?

thanks for the help Greg.

Hi,

What is the scope of an action method in struts2? I am guessing it is session based but i would like to know if there is any way to make an action method's scope to be application level.

Try this

<html:text property="serverurl" size="40" id="serverurlid" />

function openUrl(){
var x = document.fgetElementById("serverurlid").value;
}

The file i intend to write to is not in a jar. It is just present in a separate package. Is there any way to write to the file by giving a path relative to the package where the java class is present from which i am doing the writing?

Hi,

I am trying to write some data to a properties file. The file is present in a package like "com.abc.files"

When i try the following:
BufferredWriter write=new BufferredWriter(new FileWriter("com/abc/files/MyFile.properties"));

I get the following error:
"The system cannot find the path specified."

I know that by giving the full path of the file i wont get the error but is there any way to work around this?
