    <p>I have been trying to run </p> <blockquote> <p><strong>C:\Users\Luis\Desktop\RESEARCHGUIPROJECT\ResearchGUI\CHEMKED\CHEMKED_SOLVER.exe</strong></p> </blockquote> <p>using java or having java use the command prompt to run this executable. Now I believe I was to able to get java to the file but when it runs it the executable gives me <strong><em>ERR</em></strong> <em><strong>IO-21 invalid STATUS specifier for given file</em></strong>.</p> <p>I have ran the executable from the DOS window and usually when that code is given it means the input file has been specified incorrectly. To give background on the solver what it does is read from a file named <strong><em>solverfilepath.txt</em></strong> and in that file a file directory is given to where the file is located. This file is the solvers input named <strong><em>SOLTMP.txt</em></strong>.</p> <p>This error only occurs when I run java but doesn't occur when I run it manually from the command window.</p> <p>I don't know if there might be a way when java is running this program to also have it open the command window to see the executable run in the command prompt.</p> <p>Any suggestions?</p> <pre><code> int i = 1; while(finalTime &lt; 1.0000){ try{ // Execute CHEMKED solver // Added 07/06/2013 from StackOverFlow Runtime rt = Runtime.getRuntime(); String[] CHEMKED = {"C:\\Users\\Luis\\Desktop\\RESEARCHGUIPROJECT\\ResearchGUI\\CHEMKED\\CHEMKED_SOLVER.exe"}; Process pr = Runtime.getRuntime().exec(CHEMKED); BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream())); String line=null; while((line=input.readLine()) != null) { System.out.println("*****"); System.out.println(line); } int exitVal; exitVal = pr.waitFor(); System.out.println("Exited with error code "+exitVal); } catch(Exception e) { System.out.println(e.toString()); e.printStackTrace(); } try{ inputFile3 = new Scanner(new FileReader("CHEMKED\\SOLTMP.txt")); }catch(Exception e){ e.printStackTrace(System.out); } try{ copyFile = new Formatter(new File("CHEMKED\\output-ring1_"+ i +".txt")); }catch(Exception ex){ ex.printStackTrace(System.out); } //copy SOLTMP content to temporary file while(inputFile3.hasNextLine()){ fileLine = inputFile3.nextLine(); copyFile.format("%s%n",fileLine); } copyFile.close(); inputFile3.close(); // Added 07/05/2013 initialTime+= 0.10; finalTime+= 0.10; // Added 07.03 updateFile(); i++; } </code></pre> <p>So here is what I have added so far simply similar to what was done on javaWorld.

    1. COYou should be using a ProcessBuilder for this, you should be gobbling and showing the error stream as well. This line `Runtime rt = Runtime.getRuntime();` does nothing other than mislead.

    2. COI read the article from java world about gobbling and what not but I don't know how I can apply it to my code.

    3. COYou apply it just like it was likely explained in the article. You get the error stream, you put it in a BufferedReader and you display it. You are already doing this with the InputStream, so I'm confused as to why or how you're confused. But for both you will need to use background threads.

A row detail

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
