• Sql Server Compact Edition version error.

  - by Tim

  I am working on .NET ClickOnce project that uses Sql Server 2005 Compact Edition to synchronize remote data through the use of a Merge replication. This application has been live for nearly a year now, and while we encounter occasional synchronization errors, things run quite smoothly for the most part. Yesterday a user reported an error that I have never seen before and have yet to find any information for online. Many users synchronize every night, and I haven't received error reports from anyone else, so this issue must be isolated to this particular user / client machine. Here are the full details of the error: -Error Code : 80004005 -Message : The message contains an unexpected replication operation code. The version of SQL Server Compact Edition Client Agent and SQL Server Compact Edition Server Agent should match. [ replication operation code = 31 ] -Minor Error : 28526 -Source : Microsoft SQL Server Compact Edition -Numeric Parameters : 31 One interesting thing that I've found is that his data does get synchronized to the server, so this error must occur after the upload completes. I have yet to determine whether or not changes at the server are still being downloaded to his subscription. Thinking that maybe there was some kind of version conflict going on, I had a remote desktop session with this user last night and uninstalled both the application and the SQL Server Compact Edition prerequisite, then reinstalled both from our ClickOnce publication site. I also removed his existing local database file so that upon synchronization, an entirely new subscription would be issued to him. Still his errors continue. I suppose the error may be somewhat general, and the text in the error message stating that the versions should match may not necessarily reflect the problem at hand. This site contains the only official reference to this error that I've been able to find, and it offers no more detail than the error message itself. Has anyone else encountered this error? Or at least know more about SQL Compact to have a better guess as to what is going on here? Any help / suggestions will be greatly appreciated!

• Strange Sql Server 2005 behavior

  - by Justin C

  Background: I have a site built in ASP.NET with Sql Server 2005 as it's database. The site is the only site on a Windows Server 2003 box sitting in my clients server room. The client is a local school district, so for data security reasons there is no remote desktop access and no remote Sql Server connection, so if I have to service the database I have to be at the terminal. I do have FTP access to update ASP code. Problem: I was contacted yesterday about an issue with the system. When I looked in to it, it seems a bug that I had solved nearly a year ago had returned. I have a stored procedure that used to take an int as a parameter but a year ago we changed the structure of the system and updated the stored procedure to take an nvarchar(10). The stored procedure somehow changed back to taking an int instead of an nvarchar. There is an external hard drive connected to the server that copies data periodically and has the ability to restore the server in case of failure. I would have assumed that somehow an older version of the database had been restored, but data that I know was inserted 7 days and 1 day before the bug occurred is still in the database. Question: Is there anyway that the structure of a Sql Server 2005 database can revert to a previous version or be restored to a previous version without touching the actual data? No one else should have access to the server so I'm going a little insane trying to figure out how this even happened. Any ideas?

• How to maintain a persistant network-connection between two applications over a network?

  - by John

  I was recently approached by my management with an interesting problem - where I am pretty sure I am telling my bosses the correct information but I really want to make sure I am telling them the correct stuff. I am being asked to develop some software that has this function: An application at one location is constantly processing real-time data every second and only generates data if the underlying data has changed in any way. On the event that the data has changed send the results to another box over a network Maintains a persistent connection between the both machines, altering the remote box if for some reason the network connection went down From what I understand, I imagine that I need to do some reading on doing some sort of TCP/IP socket-level stuff. That way if the connection is dropped the remote location will be aware that the data it has received may be stale. However management seems to be very convinced that this can be accomplished using SOAP. I was under the impression that SOAP is more or less a way for a client to initiate a procedure from a server and get some results via the HTTP protocol. Am I wrong in assuming this? I haven't been able to find much information on how SOAP might be able to solve a problem like this. I feel like a lot of people around my office are using SOAP as a buzzword and that has generated a bit of confusion over what SOAP actually is - and is capable of. Any thoughts on how to accomplish this task would be appreciated!

• Process-to-port mapping with SNMP and/or wmi/wmic in java

  - by Niddy888

  I'm trying to use SNMP to map outgoing ports on my host computer with the application running on the computer that is responsible for that communication. When running "netstat -ano" I get access to Protocol, Local Address (with port), Foreign Address (with port), State and PID. But I want to do this entirely without having to execute "cmd" from Java. By using SNMP OID: .1.3.6.1.2.1.25.4 (.iso.org.dod.internet.mgmt.mib-2.host.hrSWRun) I get access to PID (ex. 1704), Name (ex. cmd.exe), Path (ex. C:\Windows\system32) among others. There is an SNMP OID: .1.3.6.1.2.1.6.13 (.iso.org.dod.internet.mgmt.mib-2.tcp.tcpConnTable) that give you access to TCP connection state, local address, local port, remote address, remote port. But NO PID. So to sum up. My question again: Is there a way to "map" these tables together? Either directly in SNMP with other OID's or in conjunction with WMI / WMIC?

• Connecting to an RMI object without registry

  - by Mark Probst

  I think I need to connect to a remote RMI object without going through the registry, but I don't know how. My situation is this: I'm implementing a simple job distribution service which consists of one distributor and multiple workers. The distributor has a registered RMI object to which clients connect to send jobs, and workers connect to accept jobs. Unfortunately the distributor and worker hosts are behind a firewall. To get to the distributor host I am tunneling two ports (one for the registry, one for the distributor object) via SSH, so I can get to the registry and the distributor from outside the firewall. To make that work I have to set "-Djava.rmi.server.hostname=localhost" on the distributor JVM so that the clients connect to their local, tunneled port, instead of the port on the actual distributor host, which is blocked. This creates a problem for the workers, though, because they need to connect to the distributor directly, but because of the "localhost" redirection they behave like clients and try to connect to a port on their own host, which is not available, because I'm not tunneling on the workers (it is impractical). Now, if I could connect to a remote object directly by giving the hostname and port, I could do away both with the registry on the distributor and the "localhost" hack, and make the workers connect properly. How do I do that? Or is there a different solution to this problem?

• webclient download problem!!!

  - by user472018

  Hello all, if this problem was discussed before,sorry for asking again.. I want to download an image from an url with using System.Net.WebClient class. When i try to download an image (ie. google logo).it does not occur any errors,but some images are occurring errors.I dont understand why this errors. how can i fix this problem? my Code is: WebClient client = new WebClient(); try { //Downloads the file from the given url to the given destination client.DownloadFile(urltxt.Text, filetxt.Text); return true; } catch (WebException w) { MessageBox.Show(w.ToString()); return false; } catch (System.Security.SecurityException) { MessageBox.Show("securityexeption"); return false; } catch (Exception) { MessageBox.Show("exception"); return false; } Errors are: System.Net.WebException:The underlying connection was closed:An unexpected error occurred on a recieve.--System.IO.IOException:Unable to read data from the transport connection:An existing connection was forcibly closed by the remote host.--System.Net.Sockets.SocketException:An existing connection was forcibly closed by the remote host...bla bla Thanks for your help.

• How can I get type information at runtime from a DMP file in a Windbg extension?

  - by pj4533

  This is related to my previous question, regarding pulling objects from a dmp file. As I mentioned in the previous question, I can successfully pull object out of the dmp file by creating wrapper 'remote' objects. I have implemented several of these so far, and it seems to be working well. However I have run into a snag. In one case, a pointer is stored in a class, say of type 'SomeBaseClass', but that object is actually of the type 'SomeDerivedClass' which derives from 'SomeBaseClass'. For example it would be something like this: MyApplication!SomeObject +0x000 field1 : Ptr32 SomeBaseClass +0x004 field2 : Ptr32 SomeOtherClass +0x008 field3 : Ptr32 SomeOtherClass I need someway to find out what the ACTUAL type of 'field1' is. To be more specific, using example addresses: MyApplication!SomeObject +0x000 field1 : 0cae2e24 SomeBaseClass +0x004 field2 : 0x262c8d3c SomeOtherClass +0x008 field3 : 0x262c8d3c SomeOtherClass 0:000> dt SomeBaseClass 0cae2e24 MyApplication!SomeBaseClass +0x000 __VFN_table : 0x02de89e4 +0x038 basefield1 : (null) +0x03c basefield2 : 3 0:000> dt SomeDerivedClass 0cae2e24 MyApplication!SomeDerivedClass +0x000 __VFN_table : 0x02de89e4 +0x038 basefield1 : (null) +0x03c basefield2 : 3 +0x040 derivedfield1 : 357 +0x044 derivedfield2 : timecode_t When I am in WinDbg, I can do this: dt 0x02de89e4 And it will show the type: 0:000> dt 0x02de89e4 SomeDerivedClass::`vftable' Symbol not found. But how do get that inside an extension? Can I use SearchMemory() to look for 'SomeDerivedClass::`vftable'? If you follow my other question, I need this type information so I know what type of wrapper remote classes to create. I figure it might end up being some sort of case-statement, where I have to match a string to a type? I am ok with that, but I still don't know where I can get that string that represents the type of the object in question (ie SomeObject-field1 in the above example).

• What VC++ compiler/linker does when building a C++ project with Managed Extension

  - by ???

  The initial problem is that I tried to rebuild a C++ project with debug symbols and copied it to test machine, The output of the project is external COM server(.exe file). When calling the COM interface function, there's a RPC call failre: COMException(0x800706BE): The remote procedure call failed. According to the COM HRESULT design, if the FACILITY code is 7, it's actually a WIN32 error, and the win32 error code is 0x6BE, which is the above mentioned "remote procedure call failed". All I do is replace the COM server .exe file, the origin file works well. When I checked into the project, I found it's a C++ project with Managed Extension. When I checking the DLL with reflector, it shows there's 2 additional .NET assembly reference. Then I checked the project setting and found nothing about the extra 2 assembly reference. I turned on the show includes option of compiler and verbose library of linker, and try to analyze whether the assembly is indirectly referenced via .h file. I've collect all the .h file and grep all the files with '#using' '#import' and the assembly file itself. There really is a '#using ' in one of the .h file but not-relevant to the referenced assembly. And about the linked .lib library files, only one of the .lib file is a side-product of another managed-extension-enabled C++ project, all others are produced by a pure, traditional C++ project. For the managed-extension-enabled C++ project, I checked the output DLL assembly, it did NOT reference to the 2 assembly. I even try to capture the access of the additional assembly file via sysinternal's filemon and procmon, but the rebuild process does NOT access these file. I'm very confused about the compile and linking process model of a VC++/CLI project, where the additional assembly reference slipped into the final assembly? Thanks in advance for any of your help.

• Adobe Air update error "file version doesn't match" but it's the same!...

  - by baroquedub

  I'm using Claus Wahlers' AIR Remote Updater class (codeazur.com.br/lab/airremoteupdater/). All works fine and an update is triggered if the remote version is newer. The newer file is downloaded and the update starts. However I then get "an error has occured" message: "This application cannot be installed because this installer has been mis-configured" (The same file will update without errors when run manually "Would you like to replace the currently installed version?" Choosing 'replace' works fine) I have enabled Air Application Installer logging and I can see that both the app id and the pub id match - this seems to be a common reason for this problem (forums.adobe.com/thread/243421?tstart=60) The error given in the log file is as follows: AIR file version doesn't match Requested version: ; AIR file version: 1.0.2 But if I unzip the new app file and look at META-INF\AIR\application.xml the version designator shows <version>1.0.2</version> As requested! The log file is also showing me where the newer file is being downloaded and unpacked. If I look at the application.xml file in that directory: Unpackaging to C:\Documents and Settings\myusername\Local Settings\Temp\fla893D.tmp the version designator also shows <version>1.0.2</version> I don't get it?! The log tells me that the requested file version doesn't match but it's exactly the same as what's shown in the version designator of the downloaded update package... This is driving me crazy. Can anyone help?

• Git repos over multiple machines - backups and keeping in sync

  - by a-or-b

  I'm new to git so please feel free to RTFM me... I have multiple development sites (none of which can communicate via a network with each other) and am working on a few projects (with a few people) at any one time. What I would ideally have is at each site a centralized repository that can be pulled from but development would occur in our own (personal) repos. Then I would like to be able to sync across the centralized repos (via USB key for example). I want a centralized repo at each location as (1) I'm new to git and do break my (personal) local repo by playing around and (2) some projects get put on hold so I want to be able to free up disk space by deleting them. This is the "backup" part of my question. I was also hoping to be able to use 'git clone --bare' for my centralized repos (and the USB key repos to?) as we don't need the full checkout, just the git benefits. However I can't seem to get a bare repo to work as repo I can push from. I've used 'git remote' to set up an remote origin (similar to http://toolmantim.com/thoughts/setting_up_a_new_remote_git_repository) but I can't get 'git push' to work - it seems I need a checked-out repo. . Does anyone else use this sort of repo/development structure or is there something fundamental about git usage that I'm missing? . A solution that I thought about that might not work - If I had a 'git clone --bare' at each site and then use a git repo on my removable media which has remotes set up for each site then I could ('pull') sync my USB key with each repo. But then can I update the site repo from my USB key? Could I push from USB?

• git push says everything up to date when it definitely is not

  - by Wolf

  I have a public repository. No one else has forked, pulled, or done anything else to it. I made some minor changes to one file, successfully committed them, and tried to push. It says 'Everything up-to-date'. There are no branches. I'm very, very new to git and I don't understand what on earth is going on. git remote show origin tells me: HEAD branch: master Remote branch: master tracked Local ref configured for 'git push': master pushes to master (up to date) Any ideas what I can do to make this understand that it's NOT up to date? Thanks Updates: git status: # On branch master # Untracked files: # (use "git add ..." to include in what will be committed) # # histmarkup.el # vendor/yasnippet-0.6.1c/snippets/ no changes added to commit (use "git add" and/or "git commit -a") git branch -a: * master remotes/origin/master git fsck: dangling tree 105cb101ca1a4d2cbe1b5c73eb4a238e22cb4998 dangling tree 85bd0461f0fcb1618d46c8a80d3a4a7932de34bb Update 2: I re-opened the modified file, and the modifications I KNOW I had made were gone. So I added them again, went through the rigamarole of git status, git add filename, git commit -m "(message)", and git push origin master, and all of a sudden it works the way it's supposed to.

• I need an IDE for typo3 core development in php

  - by Flugan

  Php in itself is difficult for IDEs because of the dynamic nature of the language. My current development environment is mostly netbeans against a local svn copy of the codebase setup in a local development webserver. The code is full text indexed by vistas search engine for almost instant searches. I do a lot of development directly against the main development server using a combination of tools. Putty to interact with the server and deploy by updating an svn checkout on the development server. Tortoise SVN locally to have a fairly rich SVN experience. Netbeans obviously have SVN integration. Most of the changes on the remote server is commited using the putty session. WinSCP to interact with the development server with norton commander like interface as well as the good putty integration. Finally my text editor for remote editing is notepad++ out of habit and because of some nice features and good price. What I'm really missing is good php editing. Because of the way typo3 works almost all objects are instanciated through make instance abstraction that either returns the base class or the customized class if the framework has been extended. I'm not looking for a magic editing package and would like to find an editor which can use annotations to specify the type of commonly used variables.

• What technologies/tools do people use to implement live websites ?

  - by MadSeb

  Hi, I have the following situation: -I have a server A hooked up to a piece of hardware that sends values and information out of every second. Programs on the server machine can read these values. This server A is in a very remote location so Internet connection is very slow and not reliable but the connection does exist. Let's say it's a weather station in the Arctic. -Users from the home location want to monitorize the weather values somehow. Well, the users can use a remote desktop connection the server A but that would be too too slow. My idea is somehow to have a website on a web server (let's call the webserver - B and B is in a home location ) and make the server A connect to the server B and somehow send values and the web application reads the values and displays them....... but how to do such a system ?? I know I can use MySQL and have the server A connect to a SQL server on server B and send INSERT queries and have the web application running on server B constantly read from the SQL server but I think that would be way way too slow and I think there has to be a better solution. Any ideas ? BTW. The users should be able to send information to the weather station from the website as well ( so an ADMIN user should be allowed to shut down the weather station from the website or whatever) Best regards, MadSeb

• Some sonatype nexus questions.

  - by smallufo

  I deployed a sonatype nexus server inside my LAN , mapping some remote repositories to my public repositories : First question is , why these repositories not sync with the "real" repositories ? For example , I mapped maven central (http://repo1.maven.org/maven2) to "central" , but when I browse http://smallufo:8081/nexus/content/repositories/central/org/springframework/ , the packages are not complete , in http://repo2.maven.org/maven2/org/springframework/ , there are tons of artifacts , but I only have some of them : And versions are old ... ex : spring-core is only 2.5.6.SEC01 , but the latest version is 3.0.2.RELEASE. And my maven client seems can only find the old artifacts ... "central" is a proxy directory , it should be the same with the remote server. I tried to "Expire Cache" , "ReIndex" , "Incremental ReIndex" the whole "central" : After a long time with almost 100% java process load , the situation seems not better , just add some artifacts ... not reflecting the real "Maven Central" data... Second question , what's difference with "Expire Cache" , "ReIndex" , "Incremental ReIndex" ? Even I can "search" spring-core.3.0.2.RELEASE , my m2eclipse still cannot find it : I can also see the spring-core-3.0.2.RELEASE in the "index" , (but not available in "storage") : But why m2eclipse cannot make use of it ? it seems m2eclipse can only install artifacts in the storage , if this is how nexus works , how do I "force" download spring-core-3.0.2.RELEASE to nexus's storage ? How do I solve these strange incompatibilities ? Thanks a lot !

• Why does using the Asynchronous Programming Model in .Net not lead to StackOverflow exceptions?

  - by uriDium

  For example, we call BeginReceive and have the callback method that BeginReceive executes when it has completed. If that callback method once again calls BeginReceive in my mind it would be very similar to recursion. How is that this does not cause a stackoverflow exception. Example code from MSDN: private static void Receive(Socket client) { try { // Create the state object. StateObject state = new StateObject(); state.workSocket = client; // Begin receiving the data from the remote device. client.BeginReceive( state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveCallback), state); } catch (Exception e) { Console.WriteLine(e.ToString()); } } private static void ReceiveCallback( IAsyncResult ar ) { try { // Retrieve the state object and the client socket // from the asynchronous state object. StateObject state = (StateObject) ar.AsyncState; Socket client = state.workSocket; // Read data from the remote device. int bytesRead = client.EndReceive(ar); if (bytesRead > 0) { // There might be more data, so store the data received so far. state.sb.Append(Encoding.ASCII.GetString(state.buffer,0,bytesRead)); // Get the rest of the data. client.BeginReceive(state.buffer,0,StateObject.BufferSize,0, new AsyncCallback(ReceiveCallback), state); } else { // All the data has arrived; put it in response. if (state.sb.Length > 1) { response = state.sb.ToString(); } // Signal that all bytes have been received. receiveDone.Set(); } } catch (Exception e) { Console.WriteLine(e.ToString()); } }

• PHP IDE with Integrated Web Server

  - by seth

  Note: This is not another "What is the best PHP IDE?" question. I'm looking for a PHP IDE with a specific feature, namely an integrated / embedded (php enabled) web server; ideally with xdebug pre-bundled. I already know that Aptana 1.5 has this functionality (and some older versions of Zend Studio as well), but Aptana 1.5 hasn't been supported for quite some time and as we make the transition to PHP 5.3 and beyond, it's usefulness will diminish significantly. I've looked at some options including Eclipse PDT and NetBeans, but it seems every PHP IDE relies on a separate local/remote web server to actually interpret the code. I know installing a web server locally is fairly trivial, but this is for a classroom solution, where installing, configuring, and maintaining a web server on 1000 machines is simply not feasible. A remote server solution will also not work due to the need to use debugging functionality (xdebug currently requires a hardcoded IP for the debug client). This seems like such an obvious feature/plugin for a PHP IDE, but my research thus far has turned up no results.

• Fixing merge conflicts?

  I have two remote branches, "grape" and "master". I'm currently on "grape". Now I switch to "master": git checkout master Now I want to pull all changes from "grape" into "master" - is this the way to do it?: git merge origin grape It's my understanding that git will then pull all the current state of the remote branch "grape" into my local copy of "master". It will try to auto-merge for me. If there are conflicts, the files in conflict will have some conflict text actually injected into the file. I then have to go into those files, and delete the chunk I don't want (essentially telling git how to merge these files). For each file in conflict, do I add and commit the changes again?: git add problemfile1.txt git commit -m "Fixed merge conflict." git add problemfile2.txt git commit -m "Fixed another merge conflict." ... after I've fixed all the merge conflicts like above, do I just push to "master" again to finish up the process?: git push origin master or is there something else we need to do when we get into this conflict state? Thank you

• Integrated Windows authentication in IIS causing ADO.NET failure

  - by TrueWill

  We have a .NET 3.5 Web Service running under IIS. It must use identity impersonate="true" and Integrated Windows authentication in order to authenticate to third-party software. In addition, it connects to a SQL Server database using ADO.NET and SQL Server Authentication (specifying a fixed User ID and Password in the connection string). Everything worked fine until the database was moved to another SQL Server. Then the Web Service would throw the following exception: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) This error only occurs if identity impersonate is true in the Web.config. Again, the connection string hasn't changed and it specifies the user. I have tested the connection string and it works, both under the impersonated account and under the service account (and from both the remote machine and the server). What needs to be changed to get this to work with impersonation?

• How to read the network file.

  - by ungalnanban

  I'm using Net::FTP for getting a remote hosted file. I want to read the file. I don't want to get the file from the remote host to my host (localhost), but I need to read the file content only. Is there any module to do this? use strict; use warnings; use Data::Dumper; use Net::FTP; my $ftp = Net::FTP->new("192.168.8.20", Debug => 0) or die "Cannot connect to some.host.name: $@"; $ftp->login("root",'root123') or die "Cannot login ", $ftp->message; $ftp->cwd("SUGUMAR") or die "Cannot change working directory ", $ftp->message; $ftp->get("Testing.txt") or die "get failed ", $ftp->message; $ftp->quit; In the above sample program, I get the file from 192.168.8.20. Then I will read the file and do the operation. I don't want to place the file in my local system. I need to read the Testing.txt file content.

• Cannot connect to Github?

  - by user2973438

  so I tried to push some updates onto my repo on github via terminal on Mac OSX 10.8.4 and it doesn't work. I've been getting the same error many times: Lillys-MacBook-Air:Yuewei Lilly$ git push origin master error: Failed connect to github.com:443; Operation timed out while accessing https://github.com/lillybeans/Yuewei.git/info/refs?service=git-receive-pack fatal: HTTP request failed Some background: I've pushed many projects onto github before using terminal (when I was in Canada). I am currently in Shanghai, China, could it be the GFW? But when I was in Beijing, I was able to push projects onto github still. when I do ping github.com: Lillys-MacBook-Air:Yuewei Lilly$ ping github.com PING github.com (192.30.252.131): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 ping: sendto: No route to host Request timeout for icmp_seq 2 ping: sendto: Host is down Request timeout for icmp_seq 3 ping: sendto: Host is down Request timeout for icmp_seq 4 ping: sendto: Host is down Request timeout for icmp_seq 5 ping: sendto: Host is down Request timeout for icmp_seq 6 ping: sendto: Host is down Request timeout for icmp_seq 7 ^C --- github.com ping statistics --- 9 packets transmitted, 0 packets received, 100.0% packet loss Lillys-MacBook-Air:Yuewei Lilly$ I have ShadowSocks (proxy) turned on. Without it I can't access github.com via browser, with it, I can. also when I do "git remote -v" I see both my pull and push remote repos correctly listed. Thank you in advance!

• How to send KeyEvents through an input method service to a Dialog, or a Spinner menu?

  - by shutdown11

  I'm trying to implement an input method service that receives intents sent by a remote client, and in response to those sends an appropriate KeyEvent. I'm using in the input method service this method private void keyDownUp(int keyEventCode) { getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_DOWN, keyEventCode)); getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_UP, keyEventCode)); } to send KeyEvents as in the Simple Sofykeyboard Sample, and it works in the home, in Activities... but it doesn't works when a Dialog or the menu of a Spinner is in foreground. The events is sent to the parent activity behind the Dialog. Is there any way to send keys and control the device like using the hardware keys from an input method? Better explanation on what I'm trying to do: I am kind of writng an Input Method that allows to control the device from remote. I write in a client (a java application on my desktop pc) a command (for example "UP"), a server on the device with sendBroadcast() sends the intent with the information, and a receiver in the input method gets it and call keyDownUp with the keycode of the DPAD_UP key. It generally works, but when I go to an app that shows a dialog, the keyDownUp method don't sends the key event to the dialog, for example for select the yes or not buttons, but it keeps to control the activty behind the Dialog.

• Framework or tool for "distributed unit testing"?

  - by user262646

  Is there any tool or framework able to make it easier to test distributed software written in Java? My system under test is a peer-to-peer software, and I'd like to perform testing using something like PNUnit, but with Java instead of .Net. The system under test is a framework I'm developing to build P2P applications. It uses JXTA as a lower subsystem, trying to hide some complexities of it. It's currently an academic project, so I'm pursuing simplicity at this moment. In my test, I want to demonstrate that a peer (running in its own process, possibly with multiple threads) can discover another one (running in another process or even another machine) and that they can exchange a few messages. I'm not using mocks nor stubs because I need to see both sides working simultaneously. I realize that some kind of coordination mechanism is needed, and PNUnit seems to be able to do that. I've bumped into some initiatives like Pisces, which "aims to provide a distributed testing environment that extends JUnit, giving the developer/tester an ability to run remote JUnits and create complex test suites that are composed of several remote JUnit tests running in parallel or serially", but this project and a few others I have found seem to be long dead.
