  • port binding "problem" with Eclipse, Java, & Windows

    - by Jay
    Hi All, I use eclipse to develop a web based java application. My normal course of business is grab the next task tracking ticket. If there is a problem that needs to correcting, I run the application locally, which loads of a Jetty webserver, and binds to port 8080. After verifying the problem, I fix the problem, rebuild, and the re-run the application. The problem is, I far too often forget to close the jetty server before re-running. This generates the Java bind error: WARNING: failed [email protected]:8080: java.net.BindException: Address already in use: JVM_Bind I work in Windows, and was looking to see if there is command I could run to un-bind the port, but couldn't find an answer there. Does anyone here have a good idea of how to fix my problem, other than remember to shut down the old jetty instance before starting a new one? Thanks, Jay

  • Architecture Guidance for designing Workflow Foundation with WCF

    - by Matrix
    We are planning to use WF 3.5 with WCF 3.5 and Entity Framework 1.0 for the upcoming major project. I'm looking for guidance on the architecture side. This new application will be based on typical 3-tier architecture as depicted below: Presentation Tier: ASP.NET Web Forms 3.5 Business Tier: WF 3.5 + BLL's that expose the business logic through WCF service interfaces (using EF for Data Access) Data Tier: SQL Server 2000 Here are the questions: Though the Workflow Foundation has Workflow Services, where we can map the WCF service contracts to a workflow, is this the right way to design the applications? Is EF 1.0 business entities can be used in n-tier apps without sacrificing the tracking changes in the entities? Is there a sample reference application available to look? Thanks.

  • Apache MOD_REWRITE Domain Level Cookie

    - by BigMadKev
    I need to deal with Affiliate Tracking on our website. In our .htaccess we have: RewriteCond %{QUERY_STRING} affiliate=(.*) RewriteRule ^(.*)$ $1? [NC,R,L,co=AFFID:%1:%{HTTP:Host}:7200:/] Which creates a COOKIE called AFFID with the value of the URL Parameter affiliate. But the Cookie is not for the whole domain, i.e. Going to http://www.domain.com/?affiliate=bmk sets the AFFID cookie with the value bmk for .www.domain.com but I would like ti to be for .domain.com so that it can be used across our secure domain which will be secure.domain.com Any help would be appreciated Cheers

  • Getting the download count of a specific S3 object

    - by phidah
    I've got a number of S3 objects that are available to my customers. Since I'd like to bill my customers by usage, I wondered if there is any smart kind of way to get the number of times a given file has been downloaded? Alternatively, I suppose I could parse the log files provided by S3, but with 10m+ fetches per customer this might be bit of a task. Any ideas?

  • In SharePoint, how can the "Issue ID" column of an issues list be included in the detail form (DispF

    - by Jesse C. Slicer
    We've created a pretty standard issue tracking system based off of SharePoint's template with just a few extra columns. On the list view (AllItems.aspx), the first column is called "Issue ID" and has a number. Our developers and QC use that number in discussions. However, that number doesn't seem to want to show up on the detail form (DispForm.aspx) nor in the alert email. Can this field be included in at least one of these communication methods? If so, how? Thank you.

  • Singelton on iPhone Simulator vs Singelton on real Device

    - by Helge Becker
    I am using a Singelton for some shared stuff. In the simulator, the app crashes ocasionally. Tracking the crash down shows that the the properties of my Singelton became dealocated. Those crashes never happend on a real device. Does the iPHone simulator handle memory managemend different? GC maybe? Changed the singelton to match this pattern. The iPhone Simulator dont crash now, but I am not sure about the memory handling on the real device. I assume that this solution will cause problems. What do you think?

  • Build Google App Engine Java source from Eclipse

    - by Robottinosino
    I would like to try to build Google App Engine for Java from source. I have tried this: I don't know how to solve the javac Ant task. I am on Mac OS X 10.6.8. The reason why I am trying to to create a Java Project from the source is that when I try to debug/step-into the sources downloaded from SVN, something is wrong in Eclipse and it does not track execution at the right code line. It seems to be executing "comment lines"? So I don't get an accurate tracking of the code path. I think what I would ideally need is: 1) svn checkout command with matching REV number of latest SDK 2) wget command downloading matching jar

  • Running OpenMPI on Windows XP

    - by iamweird
    Hi there. I'm trying to build a simple cluster based on Windows XP. I compiled OpenMPI-1.4.2 successfully, and tools like mpicc and ompi_info work too, but I can't get my mpirun working properly. The only output I can see is Z:\orterun --hostfile z:\hosts.txt -np 2 hostname [host0:04728] Failed to initialize COM library. Error code = -2147417850 [host0:04728] [[8946,0],0] ORTE_ERROR_LOG: Error in file ..\..\openmpi-1.4.2 \orte\mca\ess\hnp\ess_hnp_module.c at line 218 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort.

Can anyone help me? Upd2: Error code -2147024891 might be WMI error WBEM_E_INVALID_PARAMETER (0x80041008) which occures when one of the parameters passed to the WMI call is not correct. Does this mean that the problem is in OpenMPI source code itself? Or maybe it's because of wrong/outdated wincred.h and credui.lib I used while building OpenMPI from the source code?

  • How can I bring an activity to the front from a background service

    - by Erwan Pinault
    Hi, First of all, I am aware my issue is against the philosophy of Android, but I have no choice, this application will run on a embedded car gps and I need to bring an activity to prevent from car accident, for example, when it's happen around the user. I have to put other activity on the back and bring my alert pop up without user manipulation like notification on the front. Is there a way to bring manually an activity to the front, by resuming it like when you click on the android task switcher?

  • FLOT: How to make different colored points in same data series, connected by a line?

    - by Mega Matt
    Hi all, I think I may have stumbled onto a limitation of Flot, but I'm not sure. I'm trying to represent a single data series over time. The items' "State" is represented on the Y-Axis (there are 5 of them), and time is on the X-Axis (items can change states over time). I want the graph to have points and lines connecting those points for each data series. In addition to tracking an item's State over time, I'd also like to represent it's "Status" at any of the particular points. This I would like to do by changing the color of the points. What this means is a single item may have different Statuses at different times, meaning for a single data series I need a line that connects different points (dots) of different colors. The only thing I've seen so far is the ability to specify the color for all points in a given dataseries. Does anyone know if there's a way to specify colors individually? Thanks.
