• Detecting struckout text in a cell using JExcelApi

  - by Geo

  I need to detect whether the text within a cell is struck out or not. I'm using this: Cell cc = sheet.getCell("B1"); CellFormat format = cc.getCellFormat(); System.out.println(format.getFont().isStruckout()); but I remember I read somewhere that CellFormat is deprecated and CellFeatures should be used instead. How could one find out whether a text is struck out using CellFeatures?

• Calcualting Optimal Site to Site Routing using pre-computed times between sites

  - by Idistic

  Assume that I have a number of sites (locations) and the time it takes to travel from each site to each site is pre-computed Example Data - Site to Site Pre-Calculated Times in minutes From Start Site To A 20 To B 15 To C 15 From Site A To B 10 To C 15 Site B To A 10 To C 20 Site C To A 15 To B 20 4 Sites is fairly simple, but what if the site set was say 1000 sites? Given a large site set What would the best approach be to quickly find the optimal routes from the start site while visiting every other site just once? Route Solutions from Start Site for 3 sites from a start site 1 A(20) B(10) C(20) = 50 2 A(20) C(15) B(20) = 55 3 B(15) A(10) C(15) = 40 4 B(15) C(20) A(15) = 50 5 C(15) A(15) B(10) = 40 6 C(15) B(20) A(10) = 45

• How to add response headers based on Content-type, or getting Content-type before the response is co

  - by Bozho

  I want to set the Expires header for all image/* and text/css. I'm doing this in a Filter. However: before calling chain.doFilter(..) the Content-type is not yet "realized" after calling chain.doFilter(..) the Content-type is set, but so is content-length, which forbids adding new headers (at least in Tomcat implementation) I can use the extensions of the requested resource, but since some of the css files are generated by richfaces by taking them from inside jar-files, the name of the file isn't x.css, but is /xx/yy/zz.xcss/DATB/.... So, is there a way to get the Content-type before the response is committed.

• Eclipse hangs when rebuilding after the addition of an external JAR file.

  - by celestialorb

  I'm fairly new to Eclipse so if this is something simple I apologize, however when I attempt to add an external JAR file to my build path (specifically the "rt.jar" file which contains certain tools that I require) and then rebuild my project, Eclipse will hang at the end of the Build process. It'll get to 100% then just hang there using 100% of one of my CPU cores. At first I thought it may have been due to the relatively large size of the rt.jar file, but I tried using smaller JAR files and it still hung at 100%. Any help would be greatly appreciated! If there is something wrong with using the rt.jar file does anyone know of another JAR file that contains both tools for dealing with SOAP requests as well as XML/DOM manipulation? Thanks again!

• Log4j show package name

  - by Stephane Grenier

  Right now for my ConversionPattern I have: log4j.appender.A1.layout.ConversionPattern=%d{yyyy MMM dd HH:mm:ss,SSS} %5p [%t] (%F:%L) - %m%n What I'd like to do is also include the full package name with the class (%F:%L) but I can't find any config to do so in the docs. I do understand that this will be slower, but it's only for debugging and not when the system will be in production.

• Single log file for multiple webapps

  - by Ashish Aggarwal

  In my tomcat there are multiple webapps deployed and they communicate with each other. Currently they all have their own log file. But when there is some issue comes from call I have to 1st check with the app to whom I made a call and check log file of respective apps involved in the call. So I want that, as all apps is deployed in same tomcat and sharing a common log4j, if a call made to any app then all logs should be in a single log file and no matters how my webapps are involved all error comes from any webapp during the call should be in a single log file. I have no idea how can I achieve this. So any help is appreciable. Edited: I think my question is not cleared so updated with use case: I have three webapps A, B, C having logs files as A.log, B.log and C.log. I made two calls. 1st one to A (that internally calls C) and 2nd to B (that internally calls C). Now logging of first call must be in A.log (with the logs of every step performed inside the webapp c) and second call must be in B.log (with the logs of every step performed inside the webapp c).

• Any "trick" to use some keys to launch an application?

  - by Profete162

  Hello, I am currently developing an free application (TaskOS ) that allow users to have multitasking and switch easily between applications on their mobile ( like alt+tab in Windows ) That work pretty well and user can launch my application by a long press on the "search" button" by adding this line in the manifest: <action android:name="android.intent.action.SEARCH_LONG_PRESS" /> I also succeed to allow to the users to Use the camera button ( they can of course disable that in application settings) and the way to do that is slighlty different: <receiver android:name=".CameraPressed"> <intent-filter android:priority="10000"> <action android:name="android.intent.action.CAMERA_BUTTON"/> </intent-filter> I am now wondering if there are other ways to launch easily my task switcher? ( long press on Home key, long press on trackball, or any other idea.) Reading the Google documentation does not help me a lot. Any other idea/suggestion would be warmly welcome. Christophe

• Formula to draw pyramid of circles

  - by terence6

  I'm trying to create a pyramid of circles to my game, looking similar to this : But I can't make it print properly. Constantly I'm getting really strange spirals but nothing close to this. Can anyone give me some tip on proper formula ? My window is 600x600, base of pyramid is 8 . fields = new Field[BASE*(BASE/2)+4]; int line_count = BASE; int line_tmp = line_count; for(int i=0; i< fields.length; i++){ for( int j=line_tmp; j <= line_count; j++){ fields[i] = new Field(0, (150+(line_tmp*5)),(600+line_tmp*5)); } line_count--; line_tmp = line_count; }

• Resizing a GLJPanel with JOGL causes my model to disappear.

  - by badcodenotreat

  I switched over to using a GLJPanel from a GLCanvas to avoid certain flickering issues, however this has created several unintended consequences of it's own. From what I've gleaned so far, GLJPanel calls GLEventListener.init() every time it's resized which either resets various openGL functions i've enabled in init() (depth test, lighting, etc...) if i'm lucky, or completely obliterates my model if i'm not. I've tried debugging it but I'm not able to correct this behavior. This is my init() function: gl.glShadeModel( GL.GL_SMOOTH ); gl.glEnable( GL.GL_DEPTH_TEST ); gl.glDepthFunc( GL.GL_LEQUAL ); gl.glDepthRange( zNear, zFar ); gl.glDisable( GL.GL_LINE_SMOOTH ); gl.glEnable(GL.GL_NORMALIZE); gl.glEnable( GL.GL_BLEND ); gl.glBlendFunc( GL.GL_SRC_ALPHA, GL.GL_ONE_MINUS_SRC_ALPHA ); // set up the background color gl.glClearColor( ((float)backColor.getRed () / 255.0f), ((float)backColor.getGreen() / 255.0f), ((float)backColor.getBlue () / 255.0f), 1.0f); gl.glEnable ( GL.GL_LIGHTING ); gl.glLightfv( GL.GL_LIGHT0, GL.GL_AMBIENT, Constants.AMBIENT_LIGHT, 0 ); gl.glLightfv( GL.GL_LIGHT0, GL.GL_DIFFUSE, Constants.DIFFUSE_LIGHT, 0 ); gl.glEnable ( GL.GL_LIGHT0 ); gl.glTexEnvf( GL.GL_TEXTURE_ENV, GL.GL_TEXTURE_ENV_MODE, GL.GL_MODULATE ); gl.glHint( GL.GL_PERSPECTIVE_CORRECTION_HINT, GL.GL_NICEST ); // code to generate model Is there any way around this other than removing everything from init(), adding it to my display() function? Given the behavior of init() and reshape() for GLJPanel, i'm not sure if that will fix it either.

• JSF actionListener is called multiple times from within HtmlTable

  - by Rose

  I have a mix of columns in my htmltable: 1 column is an actionlistener, 2 columns are actions and other columns are simple output. <h:dataTable styleClass="table" id="orderTable" value="#{table.dataModel}" var="anOrder" binding="#{table.dataTable}" rows="#{table.rows}" <an:listenerColumn backingBean="${orderEntry}" entity="${anOrder}" actionListener="closeOrder"/ <an:column label="#{msg.hdr_orderStatus}" entity="#{anOrder}" propertyName="orderStatus" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="editOrder" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="viewOrder"/ .... I'm using custom tags, but it's the same behavior if I use the default column tags. I've noticed a very strange effect: when clicking the actionlistenercolumn, the actionevent is handled 3 times. If I remove the 2 action columns then the actionevent is handled only once. The managed bean has sessionscope, bean method: public void closeOrder(ActionEvent event) { OrdersDto order; if ((order = orderRow()) == null) { return; } System.out.println("closeOrder() 1 "); orderManager.closeOrder(); System.out.println("closeOrder() 2 "); } the console prints the'debug' text 3 times.

• What is the fastest way to learn JPA ?

  - by Jacques René Mesrine

  I'm looking for the best resources (books, frameworks, tutorials) that will help me get up to speed with JPA. I've been happily using iBatis/JDBC for my persistence needs, so I need resources that will hopefully provide comparable functions on how to do things. e.g. how to I set the isolation level for each transaction ? I know there might be 10 books on the topic, so hopefully, your recommendation could narrow down to the best 2 books. Should I start with OpenJPA or are there other opensource JPA frameworks to use ? P.S. Do suggest if I should learn JPA2 or JPA1 ? My goal ultimately is to be able to write a Google App Engine app (which uses JPA1). Thanks Jacque

• Are entities cached in jpa by default ?

  - by Nitesh Panchal

  Hello, I add entity to my database and it works fine. But when i retrieve the List, i get the old entity, the new entities i add are not shown until i undeploy the application and redeploy it again. This means are my entities cached by default? But, I haven't made any settings for caching entities in my persistence.xml or any such file. I have even tried calling flush(), refresh() and merge(). But still it shows the old entities only. Am i missing something? Please help me.

• How do I integrate GUI elements from different classes at runtime?

  - by thefourthdoctor

  I'm trying to "future-proof" an application that I'm writing by splitting out those elements that are likely to change over time. In my application I need to be able to adapt to changes in the output format (e.g. today I output to a CSV file, in the future I may need to output directly to a SQL Server database, or to a web service, etc.). I'm handling this by defining an abstract class ("OutputProvider") that I will subclass for each individual case. The one aspect of this that has me stumped is how to provide a configuration GUI that is specific to each concrete class. I have a settings dialog with a tab for output configuration. On that tab I intend to provide a drop-down to select the provider and a JPanel beneath it to hold the contents of the provider-specific GUI. How do I get the right GUI in that panel at runtime and have it behave correctly with respect to events? Also, a bonus would be if there was a way to do this such that in order to add support for new providers I could simply provide a new jar or class file to be dropped in a specific folder and the application could pick that up at startup. I'm using NetBeans and Swing.

• Return tiff file from outputstream on JSP

  - by YYY

  I am using a JSP to display a single TIFF file. The flow is as follows: I am given a PDF to convert to a TIFF. I feed a 'black box' API the PDF in the form of a File object and an OutputStream (I am currently using a ByteArrayOutputStream but that can change as needed. The 'black box' converts the PDF to a TIFF and saves the result to the OutputStream. I use out.println(outputstream) to spit out the TIFF. The problem is that I am getting a text stream instead of a displayed image. I have used the following head/meta tag: <head><title>PDF to TIFF tester</title> <META HTTP-EQUIV="Content-Script-Type" CONTENT="image/tiff"></head> <body> But that does not change the end result. Any help?

• Import? Initialize? what do to?

  - by Jeremy B

  I'm working on homework and I'm close but I am having an issue. I just learned how to work with packages in eclipse so I have a class that is importing another class from a package (I think I said that right) The main prompts the user to enter an integer between -100 and 100 and I am having an issue with validating it. I know the issue is where I'm importing I'm just unsure the direction I need to go to fix it. This is a section of my main code. (my issue starts with the last couple lines if you want to skip ahead) import myUtils.util.Console; public class ConsoleTestApp { public static void main(String args[]) { // create the Console object Console c = new Console(); // display a welcome message c.println("Welcome to the Console Tester application"); c.println(); // int c.println("Int Test"); int i = c.getIntWithinRange("Enter an integer between -100 and 100: ", -101, 101); c.println(); I have a class called Console that is located in another package that I believe I have properly imported. here is the code I am stuck on in my console class. public int getIntWithinRange(String prompt, int min, int max) { int i = 0; boolean isValid = false; while (isValid == false) { System.out.println(prompt); if (sc.hasNextInt()) { //if user chooses menu option less than 1 the program will print an error message i = sc.nextInt(); if (i < min) { System.out.println("Error! Please enter an int greater than -100"); } else if (i > max) { System.out.println("Error! Please enter an int less than 100"); } else isValid = true; } else System.out.println("Error! Invalid number value"); sc.nextLine(); } // return the int return i; } when I run this I keep getting my last print which is an invalid number value. am I not importing the code from the main method in the other console properly?

• Hibernate: Walk millions of rows and don't leak memory

  - by Autocracy

  The below code functions, but Hibernate never lets go of its grip of any object. Calling session.clear() causes exceptions regarding fetching a joined class, and calling session.evict(currentObject) before retrieving the next object also fails to free the memory. Eventually I exhaust my heap space. Checking my heap dumps, StatefulPersistenceContext is the garbage collector's root for all references pointing to my objects. public class CriteriaReportSource implements JRDataSource { private ScrollableResults sr; private Object currentObject; private Criteria c; private static final int scrollSize = 10; private int offset = 1; public CriteriaReportSource(Criteria c) { this.c = c; advanceScroll(); } private void advanceScroll() { // ((Session) Main.em.getDelegate()).clear(); this.sr = c.setFirstResult(offset) .setMaxResults(scrollSize) .scroll(ScrollMode.FORWARD_ONLY); offset += scrollSize; } public boolean next() { if (sr.next()) { currentObject = sr.get(0); if (sr.isLast()) { advanceScroll(); } return true; } return false; } public Object getFieldValue(JRField jrf) throws JRException { Object retVal = null; if(currentObject == null) { return null; } try { retVal = PropertyUtils.getProperty(currentObject, jrf.getName()); } catch (Exception ex) { Logger.getLogger(CriteriaReportSource.class.getName()).log(Level.SEVERE, null, ex); } return retVal; } }

• F5 irule with RESTful services

  - by Kyle Hayes

  I'm trying to come up with a rule on our F5 to direct traffic to our Tomcat server appropriately. We are deploying separate WAR files for each RESTful service. So, we would like to have the following URIs as an example: /services/quiz/01234/ /services/user/54321/ Where 'quiz' and 'user' are quiz.war and user.war respectively. We want to direct the traffic at the F5 level for /services/ to be the root and the rest of the URI to be directed to the Tomcat server. How do we accomplish this? Edit The browser url for a resource would look like http://www.domain.com/services/quiz/01234/ I want BIG-IP to send the request to tomcat as http://tomcatserver:8080/quiz/01234/ so basically remove /services and append everything after it to the tomcat domain. I would think this would be an easy regex, right?
