[SOLVED] How to fix java.io.IOException: Cannot run program "getContentHtml" (in directory "."): error=2, no such file exception??

I stored python script getContentHtml and InspectSite.java file in current directory

InspectSite.java code:

Code:

Process process = Runtime.getRuntime().exec("getContentHtml "+url, null, new File("./"))
...

and console print error message Cannot run program "getContentHtml" (in directory ".")
absolute path doesn't work too.

Is getContentHtml executable?

As Dugan suggests, it'll probably be a permissions issue, but why do you want to call Python from Java?

Based on the function name, you may be able to just use JSoup instead.

After reading your comment I realized that parameter "getContentHtml" should be "./getContentHtml"
