Has anyone successfully launched GetDP from another program?<br><br>I have a Java program that writes problem specification files for GetDP and then attempts to launch it. I don't understand GetDP's ""Missing number"" error message. <br>
<br>Here's the SHORT VERSION of my story. GetD itself reports:<br><br><div style="margin-left: 40px;">Running 'getdp_sparskit sample -pre EleSta_v -cal'<br>Info : Started on Fri Nov 26 13:29:57 2010<br></div>
<br>Then it produces error output as follows:<br><br><div style="margin-left: 40px;">Error : Missing number<br></div><br>Does anyone know what is the "Missing number" to which GetDP is referring? The reported command, 'getdp_sparskit sample -pre EleSta_v -cal', does run properly if I type it manually at a DOS prompt or put it in a batch file. (getdp_sparskit is my renamed getdp executable after compiling with the sparskit library.)<br>
<br>If instead I change the command line to 'getdp_sparskit sample -pre EleSta_v -cal 1>output.txt 2>errout.txt' there is more progress before it fails. I get the following normal output followed by error message:<br>
<br><div style="margin-left: 40px;">Info : Started on Fri Nov 26 13:28:24 2010<br>Info : Unknown option: '2>errout.txt'<br>Info : Loading problem definition '<a href="http://sample.pro">sample.pro</a>'<br>

</div>The solver.par file in my working directory works OK when I run from the command line, and it does not contain the characters EleSta_v, so this error message is also mysterious.<br><br>I would appreciate any insights.<br>
<br>John<br><br><br>DETAILED VERSION. Below is one version of the code I use to launch GetDP from my Java program and the resulting output. (I wrote a second version, using Java's ProcessBuilder class in hopes of seeing a different result, but the output was identical.)<br>
<br>My Java code:<br> String[] command = new String[] {<br> "getdp_sparskit",<br> "sample",<br> "-pre EleSta_v",<br> "-cal" <br> };<br>
<br> Runtime runtime = Runtime.getRuntime();<br> Process child = runtime.exec(command, null, new File(feaFolder)); /* feaFolder is working directory with <a href="http://sample.pro">sample.pro</a>, etc.*/<br>
InputStream is = child.getInputStream();<br> InputStreamReader isr = new InputStreamReader(is);<br> BufferedReader br = new BufferedReader(isr);<br> BufferedReader brErr = new BufferedReader(new InputStreamReader(child.getErrorStream()));<br>
String line;<br><br> System.out.printf("Output of running %s is:", <br> Arrays.toString(command));<br><br> while ((line = br.readLine()) != null) {<br> System.out.println(line);<br>
}<br> <br> System.out.printf("Error output of running %s is:", Arrays.toString(command));<br><br> while((line = brErr.readLine()) != null) {<br> System.out.println(line);<br>
}<br> <br> int exitVal = child.waitFor();<br><br>The exitVal = 1 indicates a not-normal exit. <br><br>Output and error message:<br><div style="margin-left: 40px;">Output of running [getdp_sparskit, sample, -pre EleSta_v, -cal] is:<br>
Info : Running 'getdp_sparskit sample -pre EleSta_v -cal'<br>Info : Started on Fri Nov 26 13:29:57 2010<br>Error output of running [getdp_sparskit, sample, -pre EleSta_v, -cal] is:Error : Missing number<br>
</div><br>The longer, more successful message reported above resulted from changing the definition of command to <br> String[] command = new String[] {<br> "getdp_sparskit",<br> "sample",<br>
"-solve EleSta_v",<br> "1>output.txt",<br> "2>errout.txt"<br> };<br><br><br>
