  • Java - strange problem storing text to a String[] and then storing the array to a Vector. Help plea

    - by hatboysam
    OK so for background I've only been using Java for a little more than a week and I am making a basic GUI "Recipe Book" application just to test out some of the techniques I've learned. Currently I'm working on the "Add New Recipe" page that allows the user to make a new recipe by adding ingredients one at a time. The ingredients have 3 attributes: Name, amount, and unit (like cups, oz, etc) that come from two text fields and a combo box respectively. The 3 values are stores as strings to a String array that represents the ingredient, then the arrays are stored in a vector that holds all of the ingredients for one recipe. When an ingredient is added, the user first types in the 3 necessary values into empty boxes/combo box dropdown and then clicks "Add Ingredient". Here is my code for when the button is clicked: public void actionPerformed(ActionEvent event) { Object source = event.getSource(); if (source == addIngredientButton) { //make sure 3 ingredient fields are not blank if (!ingredientNameField.getText().equals("") && !ingredientAmountField.getText().equals("") && !ingredientUnitDropdown.getSelectedItem().equals("")) { tempIngredientsArray[0] = ingredientNameField.getText(); //set ingredient name to first position in array tempIngredientsArray[1] = ingredientAmountField.getText(); //set ingredient amount to second position in array tempIngredientsArray[2] = (String) ingredientUnitDropdown.getSelectedItem(); //set ingredient unit to third position in array int ingredientsVectorSize = tempRecipe.ingredientsVector.size(); tempRecipe.ingredientsVector.add(this.tempIngredientsArray); //why would it matter if this and previous statement were switched for (int k = 0; k < ingredientsVectorSize + 1; k++ ) { liveIngredientsListArea.append("\n" + tempRecipe.makeIngredientSentence(k)); System.out.println(Arrays.toString(tempIngredientsArray)); //shows that tempIngredientsArray gets messed up each time } } Now here's the really strange problem I've been having. The first time the user adds an ingredient everything works fine. The second time, the String[] for that ingredient seems to be duplicated, and the third time it's triplicated. Aka the first time it runs the System.out.println might return "{Sugar, 3, Cups}" and the second time it will return "{Flour, 2, Oz.} {Flour, 2, Oz.}" etc. What's causing this strange problem? All help greatly appreciated, let me know if you need any clarification.

  • How do I get the PreviewDialog of Apache FOP to actually display my document?

    - by JRSofty
    Search as I may I have not found a solution to my problem here and I'm hoping the combined minds of StackOverflow will push me in the right direction. My problem is as follows, I'm developing a print and print preview portion of a messaging system's user agent. I was given specific XSLT templates that after transforming XML will produce a Formatting Objects document. With Apache FOP I've been able to render the FO document into PDF which is all fine and good, but I would also like to display it in a print preview dialog. Apache FOP contains such a class called PreviewDialog which requires in its constructor a FOUserAgent, which I can generate, and an object implementing the Renderable Interface. The Renderable Interface has one implementing class in the FOP package which is called InputHandler which takes in its constructor a standard io File object. Now here is where the trouble begins. I'm currently storing the FO document as a temp file and pass this as a File object to an InputHandler instance which is then passed to the PreviewDialog. I see the dialog appear on my screen and along the bottom in a status bar it says that it is generating the document, and that is all it does. Here is the code I'm trying to use. It isn't production code so it's not pretty: import java.io.BufferedOutputStream; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import java.util.Random; import javax.xml.transform.Result; import javax.xml.transform.Source; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerConfigurationException; import javax.xml.transform.TransformerException; import javax.xml.transform.TransformerFactory; import javax.xml.transform.sax.SAXResult; import javax.xml.transform.stream.StreamResult; import javax.xml.transform.stream.StreamSource; import org.apache.fop.apps.FOPException; import org.apache.fop.apps.FOUserAgent; import org.apache.fop.apps.Fop; import org.apache.fop.apps.FopFactory; import org.apache.fop.cli.InputHandler; import org.apache.fop.render.awt.viewer.PreviewDialog; public class PrintPreview { public void showPreview(final File xslt, final File xmlSource) { boolean err = false; OutputStream out = null; Transformer transformer = null; final String tempFileName = this.getTempDir() + this.generateTempFileName(); final String tempFoFile = tempFileName + ".fo"; final String tempPdfFile = tempFileName + ".pdf"; System.out.println(tempFileName); final TransformerFactory transformFactory = TransformerFactory .newInstance(); final FopFactory fopFactory = FopFactory.newInstance(); try { transformer = transformFactory .newTransformer(new StreamSource(xslt)); final Source src = new StreamSource(xmlSource); out = new FileOutputStream(tempFoFile); final Result res = new StreamResult(out); transformer.transform(src, res); System.out.println("XSLT Transform Completed"); } catch (final TransformerConfigurationException e) { err = true; e.printStackTrace(); } catch (final FileNotFoundException e) { err = true; e.printStackTrace(); } catch (final TransformerException e) { err = true; e.printStackTrace(); } finally { if (out != null) { try { out.close(); } catch (final IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } System.out.println("Initializing Preview"); transformer = null; out = null; final File fo = new File(tempFoFile); final File pdf = new File(tempPdfFile); if (!err) { final FOUserAgent ua = fopFactory.newFOUserAgent(); try { transformer = transformFactory.newTransformer(); out = new FileOutputStream(pdf); out = new BufferedOutputStream(out); final Fop fop = fopFactory.newFop( MimeConstants.MIME_PDF, ua, out); final Source foSrc = new StreamSource(fo); final Result foRes = new SAXResult(fop.getDefaultHandler()); transformer.transform(foSrc, foRes); System.out.println("Transformation Complete"); } catch (final FOPException e) { err = true; e.printStackTrace(); } catch (final FileNotFoundException e) { err = true; e.printStackTrace(); } catch (final TransformerException e) { err = true; e.printStackTrace(); } finally { if (out != null) { try { out.close(); } catch (final IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } if (!err) { System.out.println("Attempting to Preview"); final InputHandler inputHandler = new InputHandler(fo); PreviewDialog.createPreviewDialog(ua, inputHandler, true); } } // perform the clean up // f.delete(); } private String getTempDir() { final String p = "java.io.tmpdir"; return System.getProperty(p); } private String generateTempFileName() { final String charset = "abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890"; final StringBuffer sb = new StringBuffer(); Random r = new Random(); int seed = r.nextInt(); r = new Random(seed); for (int i = 0; i < 8; i++) { final int n = r.nextInt(71); seed = r.nextInt(); sb.append(charset.charAt(n)); r = new Random(seed); } return sb.toString(); } } Any help on this would be appreciated.

  • protection points in survivable mutlicast network

    - by wantobegeek
    I am working on a project on survivable multicasting.I want to propose a hybrid scheme(protection and restoration) for that purpose.Can anyone help me with an approach to decide protection points in a multicast tree??(The protection points will be those points upto which there will be an alternate path from the multicast source(protection) and from protection point to the multicast destination the path will be dynamically restored.).Pls suggest an approach to find the protection points.I found an approach name caterpillar tree which assigns the nodes on the spine of caterpillar tree as protection points.Is there any other such approach..?

  • What tools to use to build large java commercial projects ?

    - by openCage
    There are several tools to build java projects: ant mvn ivy buildr ... From my experience Ant is great for small projects and projects with special build requirements. Mvn is great for large but typical projects without too much special requirements. It also seams better for open source than for commercial projects. What would you recommend in case of large, enterprise, commercial projects ? What do you currently use and what would you rather use and why ?

  • How do I get javascript results using selenium?

    - by Seth
    I have the following code: from selenium import selenium selenium = selenium("localhost", 4444, "*chrome", "http://some_site.com/") selenium.start() sel = selenium sel.open("/") sel.type("ctl00_ContentPlaceHolder1_SuburbTownTextBox", "Adelaide,SA,5000") sel.click("ctl00_ContentPlaceHolder1_SearchImageButton") #text = sel.get_body_text() text = sel.get_html_source() print(text) The click executes a javascript file which then produces results on the same page. Obviously print(text) will only print the orignal html source. How do I get to the results of the javascript?

    hi there i have created a custom aspx page whithin my sharepoint site with a sql server connection to a database on that server to select data when i view the page it works but when another user tries to view it it gives the following error : Server Error in '/' Application. Login failed for user 'GRINCOR\GuguK'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'GRINCOR\GuguK'. Source Error: The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL: Add a "Debug=true" directive at the top of the file that generated the error. Example: <%@ Page Language="C#" Debug="true" % or: 2) Add the following section to the configuration file of your application: Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode. Important: Running applications in debug mode does incur a memory/performance overhead.
