    - by w1z
    Guys, help me... I use jni4net in my WCF service. in the ctor of the service I try to create BridgeSetup object. var bridgeSetup = new BridgeSetup(false); bridgeSetup.AddAllJarsClassPath("."); Bridge.CreateJVM(bridgeSetup); As I understand in this moment jni4ne tryes to generate jni4net.j-0.7.1.0.dll from jni4net.j-0.7.1.0.jar. It tryes to find jni4net.j-0.7.1.0.jar near the jni4net.n-0.7.1.0.dll and can't. So I get next error... c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\fileprocessingservice\76f0fa69\5db44426\assembly\dl3\4fa263c6\f424b7fa_c8ccca01\jni4net.j-0.7.1.0.DLL Anybody know how to solve the problem?

  • Which web containers install themselves well as a Windows service?

    - by Thorbjørn Ravn Andersen
    We have had a web application product for several years, and used Tomcat to deploy it under Windows as it registers itself as a Windows service so it starts and stops automatically. We may now happen to need more JEE facilitites than is provided by Tomcat (we are very tempted by the JEE 6 things in the container) so the question is which Open Source JEE containers works well as Windows services. Since Glassfish is the only JEE 6 implementation right now, it would be nice if it works well, but I'd like to hear experiences and not just what I can read from brochures. If not, what else do people use? EDIT: This goes for web containers too, and not just JEE containers. We will probably keep the necessary stack included until we find the right container and it gets JEE6 support. EDIT: I want this to work as distributed. I'm not interested in manually hacking wrappers etc., but want the installation process to handle the creation and removal of the service.

  • Problem with using APACHE-POI to convert PPT to Image

    - by SpawnCxy
    Hi all, I got a problem when I try to use Apache POI project to convert my PPT to Images.My code as follows: FileInputStream is = new FileInputStream("test.ppt"); SlideShow ppt = new SlideShow(is); is.close(); Dimension pgsize = ppt.getPageSize(); Slide[] slide = ppt.getSlides(); for (int i = 0; i < slide.length; i++) { BufferedImage img = new BufferedImage(pgsize.width, pgsize.height, BufferedImage.TYPE_INT_RGB); Graphics2D graphics = img.createGraphics(); //clear the drawing area graphics.setPaint(Color.white); graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width, pgsize.height)); //render slide[i].draw(graphics); //save the output FileOutputStream out = new FileOutputStream("slide-" + (i+1) + ".png"); javax.imageio.ImageIO.write(img, "png", out); out.close(); It works fine except that all Chinese words are converted to some squares.The png image I got is like following image: Then how can I fix this?Thanks in advance!

  • Encoding issues with Spring and Freemarker

    - by Cameron
    I'm working on a project using Freemarker and Spring running on Jetty. It will involve displaying characters from many different countries so I'm trying to set the encoding to UTF-8. However, no matter what I do, it remains ISO-8859-1. I tried to create a filter in my web.xml and I've tried putting this response.setCharacterEncoding("UTF-8"); response.setContentType("text/html; charset=utf-8"); just before rendering the view. But when I load the page and click "View Page Info", the encoding is always ISO-8859-1. I've also tried hitting my app server directly to see if it was being affected by Apache but got the same result. Any help is appreciated.

  • Streaming Video with Blackberry Simulator

    - by Jenny
    So, I wrote a quick little app for the iphone that takes in an http URL, and plays the .mp4 video located at that URL (it does more than that, of course, but that's the meat of it). Naturally, I wanted to have it on more than just a single mobile platform, so I decided to target Blackberry next. However, I'm running into a lot of problems with the Blackberry Environment. First of all, I learn that I can only download 256k files! I learn how to set that variable in my MDS simulator (and learn that this is NOT a production solution, because any end users will have to have their BES or MDS admin change the setting there). Then, I find a video less than 2 MB I can practice with. Going to the browser prompts me to save the video (rather than it playing in the browser like I expected). After saving the video, it refuses to play, saying it's the wrong format. So. I can't find a reference to IF Blackberry can stream with HTTP (i"ve heard it CAN use RTSP, though, and heard some rumors that it can't use HTTP, which would really suck). I also can't find a reference to what format blackberry uses (although I can find a million programs that will convert one file to the 'blackberry' format). Surely SOMEONE must have tried to stream video with the blackberry before. How did they go about doing so? Is it just a hopeless pipedream? Will I have to go with RTSP? Sorry for the lack of a concrete question...I'm just really lost, and I hate how so many tutorials or forum posts seem to assume I know the capabilities of the Blackberry... Edit: I finally found out that the .3gp (which I'd never heard of ) format is what Blackberry uses. Still have no idea how to stream videos off the web, though. I found a tutorial: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How%5FTo%5F-%5FPlay%5Fvideo%5Fwithin%5Fa%5FBlackBerry%5Fsmartphone%5Fapplication.html?nodeid=1383173&vernum=0 That seemed to be useful, but the code doesn't work if you give it a URL (even though it claims it does).

  • Algorithm for analyzing text of words

    - by Click Upvote
    I want an algorithm which would create all possible phrases in a block of text. For example, in the text: "My username is click upvote. I have 4k rep on stackoverflow" It would create the following combinations: "My username" "My Username is" "username is click" "is click" "is click upvote" "click upvote" "i have" "i have 4k" "have 4k" .. You get the idea. Basically the point is to get all possible combinations of 'phrases' out of a sentence. Any thoughts for how to best implement this?

  • Best tools to monitor Tomcat

    - by Pier Luigi
    Hi all, I'm searching free tools for monitor tomcat (traffic, memory usage, threads, requests, CPU, logs,...). I'm currently using lambdaprobe on Tomcat 5.5.x, but it seems that is no more developed (or not? the site lambdaprobe.org is always down for me...). Has someone good experiences to share? In lambdaprobe there are some info available only if tomcat is instrumented with JMX. Well, JMX is something of strange and mysterious for me. Is a good solution in a production server? It's worth to spend my (little) time to learn it?

  • Playing online video on iphone web, the iphone seems to cache the reference movie

    - by Mad Oxyn
    We are working on an online mobile video app, and are trying to play a reference movie on an iphone from the iphone browser. The problem is, the movie plays the first time, but when we try to play a different movie the second time, it doesnt. Quicktime gives a general error message sayin "Cannot Play Movie". More precisely this is what we are trying to do: Connect with an iPhone to a webserver that serves a reference movie (generated with quicktime pro). The ref movie automatically gets downloaded to the iphone by quicktime. Quicktime then chooses one of the 3 references in the reference movie, based on the connection speed, and tries to download the designated movie via a relative path. A servlet gets called and forwards the relative path to the right movie. This all works the first time. However the second time when we want download different movies, we get the quicktime error. Test case: Open reference movie 1 Movie plays in Quicktime Open reference movie 2 ERROR: Quicktime gives an error - Cannot Play Movie Shut down Iphone Turn Iphone on again Open reference movie 2 Iphone plays movie Open movie ERROR: Quicktime gives an error - Cannot Play Movie Did anyone encounter similar issues with quicktime and the use of reference movies and is there something we can do to work around that?

  • lwjgl 101: How can I write the basics?

    - by Vuntic
    This ought to be really simple, but I cannot for the life of me figure out how to compile anything with lwjgl and have it work. I can write something like package gwison; import org.lwjgl.Sys; public class G { public static void main(String[] args) { System.out.println(Sys.getTime()); } } and I can easily compile a program with several classes in different packages, as long as I wrote all the classes myself. But I have no clue how to make G work. I think it has something to do with classpathes? Maybe? Help?

  • “if” statement vs OO Design - 2

    - by hilal
    I encountered similar problem “if” statement vs OO Design - 1 but it is slightly different. Here is the problem that open the popup (different objects/popups) onValueChange of listbox Popup1 p1; // different objects Popup2 p2; // different objects Popup3 p3; ... listbox.add("p1"); listbox.add("p2"); listbox.add("p3"); ... listbox.addChangeHandler() { if(getSelectedItem().equals("p1")){ p1 = new Popup1(); p1.show(); } else if() {...} .... } I don't want to write "if" that if p1 then p1 = new Popup1(); p1.center(); How I can handle this situation? Any design-pattern? Here is my solution but it is so costly map() { map.put("p1", new Popup1()); map.put("p2", new Popup2()); map.put("p3", new Popup3()); } onValueChange() { map.get(selectedItem).show(); } One drawback is initialization all the popups. but it is require only when valueChange

    I am using an LGPL library in my code. For my needs, I need to modify the code in the library. How do I mark the jar file that it contains modified code? Some txt file in the jar? In that case, what do I write in the txt file? I will include in the license agreement that we are distributing a modified version of the jar, but my question is about marking the jar itself.

    I'm dynamically creating buttons.

  • sermyadmin 2.01

    - by lepricon123
    I am able to install sermyadmin 2.0.1 and got everything working. Only user registration is not working. When I register a user the entry goe sin DB etc find but the email is not send to the user. We are using our own smtp server with no authentication. And I am sure there is nothing wrong with the smtp server. I can see that it has received a request from sermyadmin but in the logs Is ee that the FROM adddress is missing. So it is throwing 553 5.1.8 Domain of sender address does not exist. The domain does exist. Here is my resources.xml with all the valid entries. Since I don;t need the smtp authentication which the server is not using, i removed that. <beans xmlns="www.springframework.org/schema/beans" xmlns:xsi="www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" www.springframework.org/schema/beans www.springframework.org/schema/beans/spr...ns-2.0.xsd"> <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host" value="10.100.22.365" /> </bean> <bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage"> <property name="from" value="[email protected]" /> </bean> </beans>

  • algorithm to combinatorics

    - by peiska
    I am trying to solve a combinatorics problem, it seems easy, but i am having some trouble with it. If i have at most X tables, and N persons to sit on the tables, Each table can have 1 to N seating places, and I can only sit persons in one side of a rectangular table( so the order how people sit matters). I want to make a code that can calculate all the distributions of seating places from 1 up to K tables. For example, if I have 12 persons and 1 table i have 479001600 ways of seating persons( thats easy to calculate I've used Factorial of 12). But if I have 12 persons and 3 tables i have 4390848000 ways of seating persons. I've tried different solutions but i was not able to find the correct one. I've tried to divided the 12 in 3, then o use factorial of the result (it didnt work), i've tried to use 12! * 3( it didn't work too). Can some one give me a tip in a algorithm that i can use?

  • Managed language for scientific computing software

    - by heisen
    Scientific computing is algorithm intensive and can also be data intensive. It often needs to use a lot of memory to run analysis and release it before continuing with the next. Sometime it also uses memory pool to recycle memory for each analysis. Managed language is interesting here because it can allow the developer to concentrate on the application logic. Since it might need to deal with huge dataset, performance is important too. But how can we control memory and performance with managed language?

  • Problem creating a mosaic of images using JAI

    Hello I'm trying to use JAI to create a single mosaic consisting of 4 TIF images each of which is 5000 x 5000. The code I have written is as follows .. RenderedOp mosaic=null; ParameterBlock pbMosaic=new ParameterBlock(); pbMosaic.add(MosaicDescriptor.MOSAIC_TYPE_OVERLAY); RenderedOp in=null; // Get 4 tiles and add them to the Mosaic in=returnRenderedOp(path,"northwest.tif"); pbMosaic.addSource(in); in=returnRenderedOp(path,"northeast.tif"); pbMosaic.addSource(in); in=returnRenderedOp(path,"southwest.tif"); pbMosaic.addSource(in); in=returnRenderedOp(path,"southeast.tif"); pbMosaic.addSource(in); // Setup the ImageLayout ImageLayout imageLayout=new ImageLayout(0,0,10000,10000); imageLayout.setTileWidth(5000); imageLayout.setTileHeight(5000); imageLayout.setColorModel(in.getColorModel()); imageLayout.setSampleModel(in.getSampleModel()); mosaic=JAI.create("mosaic",pbMosaic,new RenderingHints(JAI.KEY_IMAGE_LAYOUT,imageLayout)); The problem is that all 4 images are being positioned in the same place in the top left hand corner of the mosaic so the other three quarters of it is empty. Can anyone tell me how I can choose the position of each picture that makes up the mosaic so each appears in the correct place ? Thanks Ian
