    <p>I am trying to implement a web service which triggers OCR actions of the server side. </p> <p>Client code:</p> <pre><code>... sy = belgeArsivle(testServisIstegi, ab); ... private static ServisYaniti belgeArsivle(com.ocr.ws.ServiceRequest serviceRequest,com.ocr.ws.Document document) { com.ocr.ws.ServiceRequest service = new com.ocr.ws.OCRArsivWSService(); com.ocr.ws.OCRArsivWS port = service.getOCRArsivWSPort(); return port.docArchive(serviceRequest, document); } </code></pre> <p>When I run the code on the server side there is no problem. But whenever I call the web service method from the client I got this error code:</p> <pre><code>Exception: javax.xml.ws.soap.SOAPFaultException: Unable to load library 'libtesseract302': The specified module could not be found. </code></pre> <p>The working server-side code is:</p> <pre><code>public static void main(String[] args) { // TODO code application logic here File imageFile = new File("...OCR\\testTurWithBarcodeScanned.png"); Tesseract instance = Tesseract.getInstance(); try { String lang = "tur"; instance.setLanguage(lang); String result = instance.doOCR(imageFile); System.out.println(result); // write in a file try { File file = new File("...MyOutputWithBarcode.txt"); BufferedWriter out = new BufferedWriter(new FileWriter(file)); out.write(result); out.close(); } catch (IOException ex) { } } catch (TesseractException ep) { System.err.println(ep.getMessage()); } } </code></pre> <p>I know that this error code is about Tesseract libraries. I put the corresponding .dll files (liblept168 and libtesseract302) under the client project's folder, added corresponding libraries (jna, jai_imageio, ghost4j_0.3.1), did neccessary changes in classpath but still getting this error. </p> <p>I run a test code on the server side, it works fine. But the client side code is not working. Do I need to make some extra adjustment on the client side to run this web service?</p>

    1. CONot related to the problem at hand, but you may want to use `new BufferedWriter(new OutputStreamWriter(new FileOutputStream(textFile), "utf8"));` to preserve the Unicode character outputs from Tesseract.

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.
