    <p>I am calling a Python script from my Java code. This is the code : </p> <pre> import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class JavaRunCommand { public static void main(String args[]) throws IOException { // set up the command and parameter String pythonScriptPath = "my-path"; String[] cmd = new String[2]; cmd[0] = "python2.6"; cmd[1] = pythonScriptPath; // create runtime to execute external command Runtime rt = Runtime.getRuntime(); Process pr = rt.exec(cmd); // retrieve output from python script BufferedReader bfr = new BufferedReader(new InputStreamReader( pr.getInputStream())); String line = ""; while ((line = bfr.readLine()) != null) { // display each output line form python script System.out.println(line); } } } </pre> <p><b> python.py </b> which works</p> <pre> import os from stat import * c = 5 print c </pre> <p><b> python.py </b> which does not works</p> <pre> import MySQLdb import os from stat import * c = 5 print c # some database code down </pre> <p>So, I am at a critical stage where I have a deadline for my startup and I have to show my MVP project to the client and I was thinking of calling Python script like this. It works when I am printing anything without dB connection and MySQLdb library. But when I include them, it does not run the python script. Whats wrong here. Isnt it suppose to run the process handling all the inputs. I have MySQLdb installed and the script runs without the java code. </p> <p>I know this is not the best way to solve the issue. But to show something to the client I need this thing working. Any suggestions ?</p>

    2. CODoes your python script run from a command shell outside of java? Possibly Python in the command shell can't find the library. Check out this q: http://stackoverflow.com/questions/135035/python-library-path and print sys.path both from java & stand alone

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
