• Problem with copying local data onto HDFS on a Hadoop cluster using Amazon EC2/ S3.

  - by Deepak Konidena

  Hi, I have setup a Hadoop cluster containing 5 nodes on Amazon EC2. Now, when i login into the Master node and submit the following command bin/hadoop jar <program>.jar <arg1> <arg2> <path/to/input/file/on/S3> It throws the following errors (not at the same time.) The first error is thrown when i don't replace the slashes with '%2F' and the second is thrown when i replace them with '%2F': 1) Java.lang.IllegalArgumentException: Invalid hostname in URI S3://<ID>:<SECRETKEY>@<BUCKET>/<path-to-inputfile> 2) org.apache.hadoop.fs.S3.S3Exception: org.jets3t.service.S3ServiceException: S3 PUT failed for '/' XML Error Message: The request signature we calculated does not match the signature you provided. check your key and signing method. Note: 1)when i submitted jps to see what tasks were running on the Master, it just showed 1116 NameNode 1699 Jps 1180 JobTracker leaving DataNode and TaskTracker. 2)My Secret key contains two '/' (forward slashes). And i replace them with '%2F' in the S3 URI. PS: The program runs fine on EC2 when run on a single node. Its only when i launch a cluster, i run into issues related to copying data to/from S3 from/to HDFS. And, what does distcp do? Do i need to distribute the data even after i copy the data from S3 to HDFS?(I thought, HDFS took care of that internally) IF you could direct me to a link that explains running Map/reduce programs on a hadoop cluster using Amazon EC2/S3. That would be great. Regards, Deepak.

• one page has more than one url. search engines give penalty please help me out.

  - by Ali Demirtas

  Hi I am using prestashop as the cart for my website. I have a problem; the website used to be in dynamic urls. I enabled friendly url writing. The problem is that one page has more than one url. You can access a same page from the dynamic url and static url. In fact a single page has 9 different urls. This obviously creates problems for seo as search engiones penalize my website for this. What can I do to solve this problem? I have no knowledge of programming. Here is the htaccess for the website. Any sample code or help is really appreciated.

• No acceleration for OpenGL and ImportError for modules that exist

  - by Aku

  I'm writing a program using wxPython and OpenGL. The program works, but without any antialiasing, and I get these error messages: (I'm using ArchLinux) INFO:OpenGL.acceleratesupport:No OpenGL_accelerate module loaded: No module named OpenGL_accelerate INFO:OpenGL.formathandler:Unable to load registered array format handler numpy: Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/OpenGL/arrays/formathandler.py", line 44, in loadPlugin plugin_class = entrypoint.load() File "/usr/lib/python2.6/site-packages/OpenGL/plugins.py", line 14, in load return importByName( self.import_path ) File "/usr/lib/python2.6/site-packages/OpenGL/plugins.py", line 28, in importByName module = __import__( ".".join(moduleName), {}, {}, moduleName) File "/usr/lib/python2.6/site-packages/OpenGL/arrays/numpymodule.py", line 11, in <module> raise ImportError( """No numpy module present: %s"""%(err)) ImportError: No numpy module present: No module named numpy INFO:OpenGL.formathandler:Unable to load registered array format handler numeric: Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/OpenGL/arrays/formathandler.py", line 44, in loadPlugin plugin_class = entrypoint.load() File "/usr/lib/python2.6/site-packages/OpenGL/plugins.py", line 14, in load return importByName( self.import_path ) File "/usr/lib/python2.6/site-packages/OpenGL/plugins.py", line 28, in importByName module = __import__( ".".join(moduleName), {}, {}, moduleName) File "/usr/lib/python2.6/site-packages/OpenGL/arrays/numeric.py", line 15, in <module> raise ImportError( """No Numeric module present: %s"""%(err)) ImportError: No Numeric module present: No module named Numeric However, when I look into my site-packages folder, I see those modules present there.

(The code is over 200 lines, if necessary I'll edit this and put it here.)

• Azure application working on emulator but not on azure cloud

  - by Hisham Riaz

  firstly i am developing my MVC3 application on visual web developer 2010 express, by migrating my MVC3 (cshtml) files on MVC2. it works great on local system using the emulator, but once i deploy the application on azure it gives runtime errors. example: The layout page "~/Views/Shared/test_page.cshtml" could not be found at the following path: "~/Views/Shared/test_page.cshtml". Source Error: Line 8: //Layout = "~/Views/Shared/upload.cshtml"; Line 9: //Layout = "~/Views/Shared/_Layout2.cshtml"; Line 10: Layout = "~/Views/Shared/test_page.cshtml"; Line 11: } Line 12: else CODE IS AS FOLLOWS: _ViewStart.cshtml file @{ string AccId = Request.QueryString["AccId"].ToString(); if (AccId=="0") { //Layout = "~/Views/Shared/upload.cshtml"; //Layout = "~/Views/Shared/_Layout2.cshtml"; Layout = "~/Views/Shared/test_page.cshtml"; } else { string LayOutPagePath = MVCTest.Models.ComponentClass.GetLayOutPagePath(AccId); Layout = LayOutPagePath; } } ......... how ever the page exist, and is working fine on azure emulator, but not in azure cloud.

• Write a compiler for a language that looks ahead and multiple files?

  - by acidzombie24

  In my language I can use a class variable in my method when the definition appears below the method. It can also call methods below my method and etc. There are no 'headers'. Take this C# example. class A { public void callMethods() { print(); B b; b.notYetSeen(); public void print() { Console.Write("v = {0}", v); } int v=9; } class B { public void notYetSeen() { Console.Write("notYetSeen()\n"); } } How should I compile that? what i was thinking is: pass1: convert everything to an AST pass2: go through all classes and build a list of define classes/variable/etc pass3: go through code and check if there's any errors such as undefined variable, wrong use etc and create my output But it seems like for this to work I have to do pass 1 and 2 for ALL files before doing pass3. Also it feels like a lot of work to do until I find a syntax error (other than the obvious that can be done at parse time such as forgetting to close a brace or writing 0xLETTERS instead of a hex value). My gut says there is some other way. Note: I am using bison/flex to generate my compiler.

• PLKs and Web Service Software Factory

  - by Nix

  We found a bug in Web Service Software Factory a description can be found here. There has been no updates on it so we decided to download the code and fix it ourself. Very simple bug and we patched it with maybe 3 lines of code. However* we have now tried to repackage it and use it and are finding that this is seemingly an impossible process. Can someone please explain to me the process of PLKs? I have read all about them but still don't understand what is really required to distribute a VS package. I was able to get it to load and run using a PLK obtained from here, but i am assuming that you have to be a partner to get a functional PLK that will be recognized on other peoples systems? Every time i try and install this on a different computer I get a "Package Load Failure". Is the reason I am getting errors because I am not using a partner key? Is there any other way around this? For instance is there any way we can have an "internal" VS package that we can distribute? Edit Files I had to change to get it to work. First run devenv PostInstall.proj Generate your plks and replace ##Package PLK## (.resx files) --Just note that package version is not the class name but is "Web Service Software Factory: Modeling Edition" -- And you need to remove the new lines from the key ProductDefinitionRegistryFragment.wxi line 1252(update version to whatever version you used in plk) Uncomment all // [VSShell::ProvideLoadKey("Standard", Constant in .tt files.

• GridView not DataBinding Automatically after ObjectDataSource Select Method

  - by John Polvora

  I've created a objectadasource that returns a datatable, the gridview is binded to this datasource. the ODS have parameters assigned on the Page_Load event, and the ODS returns the data ok and the gridview shows it fine. the problem is i have a textbox with a filter. first I created a filterexpression in gridview, using the contents of the textbox, worked fine for me. but now I've enabled the paging in gridview. then the filterexpression is not useful now, since the ODS returns only the rows of the pagesize of gridview. I did a new ODS method that select data from parameters page and pagesize according to GridView, and it's OK. now my filter textbox passes his text property to a parameter of the ods select method, then the ods gets the data based on my filter and shows it in the grid. on the Page_Load: ObjectDataSource_Lista.SelectParameters["search"].DefaultValue = filter; ObjectDataSource_Lista.SelectParameters["id"].DefaultValue = ID.ToString(); but when I change the value of the filter, the grid doesn't refresh. on debugging. I see that the ODS Select Method is refreshed ok, but the GridView don't. So I need to call mannually the Databind() method of the grid, to refresh data. the problem is, I have a commandbutton on the grid, and if I manually databind(), the command button stops functioning, generating Page ValidateRequest errors. My question is: how to databind() the grid automatically after the datasource refreshed? ps: on the ODS Selected event, causes a infinite loop and the debug webserver crashes. Temporary solution: Created a Variable private bool wasdatabound; on the event GridView_Databound, set wasdatabound = true; on the Page_PreRenderComplete, if ((GridView1.Visible) && (!databounded)) GridView1.DataBind();

• using ontouch to zoom in

• Mysql latin1 turkish data and delphi 2010 utf8

  - by sabri.arslan

  Hello, I have tables collating latin1_general_ci and have turkish character values. And i can use this data on delphi 7+zeos with no problem. but i want to upgrade my delphi to 2010 version but zeos too slow as i saw. so i want to use odbc+ado or dbexpress solution. dbexpress solution works fine , display my data as entered and write as entered table without any change to column charset. but dbexpress has problems as i saw. for example when i select * from table which has column types as varchar,decimal,int,tinyint,text give av errors on xp systems. vista and 7 does not give any error and work fine(not fully tested). ado solution(dbgo) works fine but its not show my data as entered.its want everything be utf. but i don't want to convert my data to utf before test everything. how can i see my data as entered and write client side utf and store latin1(as zeos or dbexpress do). i was tried many other options. eg. mysql side collation and charset parameters. sorry for my bad english. i hope someone understand me. thanks.

• Are CMake GLOB and source_group compatible?

  - by jwfearn

  I'm using CMake 2.8.0 (on Windows) with the "Visual Studio 10 Win64" generator. GLOB and source_group don't seem to work together. Is there a way to get this to work? I use file( GLOB ... ) to create a list of .cpp files and then use source_group to create a filter in the generated Visual Studio project: # C:\Users\My Name\hello\CMakeLists.txt cmake_minimum_required( VERSION 2.8 ) project( hello_proj ) file( GLOB HELLO_SRCS *.cpp ) message( "HELLO_SRCS="${HELLO_SRCS} ) #source_group( hello_group ${HELLO_SRCS} ) #line 6: uncomment to get error add_executable( hello_exec ${HELLO_SRCS} ) with line 6 commented out, the project is generated fine: HELLO_SRCS=C:/Users/My Name/hello/hello.cppC:/Users/My Name/hello/print_line.cpp -- Configuring done -- Generating done -- Build files have been written to: C:/Users/My Name/hello with line 6 un-commented, I get an error: HELLO_SRCS=C:/Users/My Name/hello/hello.cppC:/Users/My Name/hello/print_line.cpp CMake Error at CMakeLists.txt:6 (source_group): source_group Unknown argument "C:/Users/My Name/hello/hello.cpp". Perhaps the FILES keyword is missing. -- Configuring incomplete, errors occurred! I notice that output value of ${HELLO_SRCS} does not seem to contain any delimiters between the file names, nor does it have quotes or other delimiters wrapping the file names which contain spaces. Does that have anything to do with my problem? Renaming all directories to avoid spaces is not really an option.

• iPhone: addAnnotation not working when called from another view

  - by Nic Hubbard

  I have two views, the first view has an MKMapView on it named ridesMap. The second view is just a view with a UITableView in it. When you click the save button in the second view, it calls a method from the first view: // Get my first views class MyRidesMapViewController *rideMapView = [[MyRidesMapViewController alloc] init]; // Call the method from my first views class that removes an annotation [rideMapView addAnno:newRidePlacemark.coordinate withTitle:rideTitle.text withSubTitle:address]; This correctly calls the addAnno method, which looks like: - (void)addAnno:(CLLocationCoordinate2D)anno withTitle:(NSString *)annoTitle withSubTitle:(NSString *)subTitle { Annotation *ano = [[[Annotation alloc] init] autorelease]; ano.coordinate = anno; ano.title = annoTitle; ano.subtitle = subTitle; if ([ano conformsToProtocol:@protocol(MKAnnotation)]) { NSLog(@"YES IT DOES!!!"); } [ridesMap addAnnotation:ano]; }//end addAnno This method creates an annotation which does conform to MKAnnotation, and it suppose to add that annotation to the map using the addAnnotation method. But, the annotation never gets added. I NEVER get any errors when the annotation does not get added. But it never appears when the method is called. Why would this be? It seems that I have done everything correctly, and that I am passing a correct MKAnnotation to the addAnnotation method. So, I don't get why it never drops a pin? Could it be because I am calling this method from another view? Why would that matter?

• Debugging NSoperation BAD ACCESS within graphics context

  - by Joe

  I tried everything to debug this one but I can't get to the bottom of it. This code lives in a subclass of NSOperation which is processed from a queue: (borders is an ivar NSArray containing 5 UIimage objects) NSMutableArray *images = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < 5; i++) { CGSize size = CGSizeMake(60, 60); UIGraphicsBeginImageContext(size); CGPoint thumbPoint = CGPointMake(6, 6); [controller.image drawAtPoint:thumbPoint]; CGPoint borderPoint = CGPointMake(0, 0); [[borders objectAtIndex:i] drawAtPoint:borderPoint]; [images addObject:UIGraphicsGetImageFromCurrentImageContext()]; UIGraphicsEndImageContext(); } [images release]; The code works fine most of the time but when I push the iphone by access subviews and pressing lots of buttons on the UI I either get this exception which is trapped by the operation: Exception Load view: *** -[NSCFArray insertObject:atIndex:]: attempt to insert nil or I get this: Program received signal: “EXC_BAD_ACCESS”. The exception is caused because UIGraphicsGetImageFromCurrentImageContext() return nil. I don't know how to debug the EXC_BAD_ACCESS but I'm guessing that this error (in fact both of these errors) is caused by low memory. The debugger stops at the line: [controller.image drawAtPoint:thumbPoint]; As I mentioned I've trapped the exception so I can live with that but the EXC_BAD_ACCESS is more serious. IF this is memory related how can I tell and is it possible to increase the memory available to NSOperation?

• Flash gets XML but the values are wrong, as3

  - by VideoDnd

  Flash receives the XML, but the values are wrong. How do I fix this? Problem I can see the XML loaded with no errors, but my output is way off. It's as though it's not receiving any values. Numbers in the output window and animation move rapidly. The Flash file runs as if it's variables where set to zero. I changed the order of my code, but that didn't help with this. Please explain how I can correct this.

• Why does the MSCVRT library generate conflicts at link time?

  - by neuviemeporte

  I am building a project in Visual C++ 2008, which is an example MFC-based app for a static C++ class library I will be using in my own project soon. While building the Debug configuration, I get the following: warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library After using the recommended option (by adding "msvcrt" to the "Ignore specific library" field in the project linker settings for the Debug configuration), the program links and runs fine. However, I'd like to find out why this conflict occured, why do I have to ignore a critical library, and if I'm to expect problems later I if add the ignore, or what happens if I don't (because the program builds anyway). At the same time, the Release configuration warns: warning LNK4075: ignoring '/EDITANDCONTINUE' due to '/OPT:ICF' specification warning LNK4098: defaultlib 'MSVCRTD' conflicts with use of other libs; use /NODEFAULTLIB:library I'm guessing that the "D" suffix means this is the debug version of the vc++ runtime, no idea why this gets used this time. Anyway, adding "msvcrtd" to the ignore field causes lots of link errors of the form: error LNK2001: unresolved external symbol imp_CrtDbgReportW Any insight greatly appreciated.

• Yacc and Lex inclusion confusion

  - by thejohnmeister

  I am wondering how to correctly compile a program with a Makefile that has calls to yyparse in it? This is what I do: I have a Makefile that compiles all my regular files and they have no connections to y.tab.c or lex.yy.c (Am I supposed to have them?) I do this on top of my code: #include "y.tab.c" #include "lex.yy.c" #include "y.tab.h" This is what happens when I try to make the program: When I just type in "make", it gives me many warnings. Some of the examples are shown below. In function yywrap': /src/parser.y:12: multiple definition ofyywrap' server.o :/src/parser.y:12: first defined here utils.o: In function yyparse': /src/y.tab.c:1175: multiple definition ofyyparse' server.o:/src/y.tab.c:1175: first defined here utils.o I get many different errors referring to different yy_* files. I have compiled successfully with multiple calls to yyparse in the past, but this time seems to be different. It seems an awful lot like an inclusion problem somewhere but I can't tell what it is. All my header files have ifndef conditions, as well. Thanks for your help!

• RHEL 5.3 Kickstart - How specify location of individual package in Workstation folder?

  - by Ed

  I keep getting "package does not exist" errors during the install. I made a kickstart ISO to create an unattended install of a RHEL 5.3 build machine for C++ software releases. It pulls the kickstart config file from our internal web server. This is handy; it makes it easy to test and modify without having to make a new ISO. And I plan to check it in to version control if I can get it working. Anyway, the rpm packages are located in two folders on the disk; Client and Workstation. The packages install fine for the ones that are physically located under the Client folder. It cannot find those under the Workstation folder such as as doxygen and subversion complaining that packages do not exist. Is there a way to specify the individual package location? # ----------------------------------------------------------------------------- # P A C K A G E S # ----------------------------------------------------------------------------- %packages @gnome-desktop @core @base @base-x @printing @development-tools emacs kexec-tools fipscheck xorg-x11-server-Xnest xorg-x11-server-Xvfb #Packages Located in Workstation Folder *** Install can not find any of these ?? bison doxygen gcc-c++ subversion zlib-devel freetype-devel libxml2-devel Thanks in advance, -Ed

• DjangoUnicodeDecodeError while storing pickle'd data.

  - by Jack M.

  I've got a simple dict object I'm trying to store in the database after it has been run through pickle. It seems that Django doesn't like trying to encode this error. I've checked with MySQL, and the query isn't even getting there before it is throwing the error, so I don't believe that is the problem. The dict I'm storing looks like this: { 'ordered': [ { 'value': u'First\xd1ame Last\xd1ame', 'label': u'Full Name' }, { 'value': u'123-456-7890', 'label': u'Phone Number' }, { 'value': u'[email protected]', 'label': u'Email Address' } ], 'cleaned_data': { u'Phone Number': u'123-456-7890', u'Full Name': u'First\xd1ame Last\xd1ame', u'Email Address': u'[email protected]' }, 'post_data': <QueryDict: { u'Phone Number': [u'1234567890'], u'Full Name_1': [u'Last\xd1ame'], u'Full Name_0': [u'First\xd1ame'], u'Email Address': [u'[email protected]'] }>, 'user': <User: itis> } The error that gets thrown is: 'utf8' codec can't decode bytes in position 52-53: invalid data. Position 52-53 is the first instance of \xd1 (Ñ) in the pickled data. So far, I've dug around StackOverflow and found a few questions where the database encoding for the objects was wrong. This doesn't help me because there is no MySQL query yet. This is happening before the database. Google also didn't help much when searching for unicode errors on pickled data. It is probably worth mentioning that if I don't use the Ñ, this code works fine.

• Academic question: typename

  - by Arman

  Hi, recently I accounted with a "simple problem" of porting code from VC++ to gcc/intel. The code is compiles w/o error on VC++: #include <vector> using std::vector; template <class T> void test_vec( std::vector<T> &vec) { typedef std::vector<T> M; /*==> add here typename*/ M::iterator ib=vec.begin(),ie=vec.end(); }; int main() { vector<double> x(100, 10); test_vec<double>(x); return 0; } then with g++ we have some unclear errors: g++ t.cpp t.cpp: In function 'void test_vec(std::vector<T, std::allocator<_CharT> >&)': t.cpp:13: error: expected `;' before 'ie' t.cpp: In function 'void test_vec(std::vector<T, std::allocator<_CharT> >&) [with T = double]': t.cpp:18: instantiated from here t.cpp:12: error: dependent-name 'std::M::iterator' is parsed as a non-type, but instantiation yields a type t.cpp:12: note: say 'typename std::M::iterator' if a type is meant If we add typename before iterator the code will compile w/o pb. If it is possible to make a compiler which can understand the code written in the more "natural way", then for me is unclear why we should add typename? Which rules of "C++ standards"(if there are some) will be broken if we allow all compilers to use without "typename"? kind regards Arman.

• COM: How to handle a specific exception?

  - by Ian Boyd

  i'm talking to a COM object (Microsoft ADO Recordset object). In a certain case the recordset will return a failed (i.e. negative) HRESULT, with the message: Item cannot be found in the collection corresponding to the requested name or ordinal i know what this error message means, know why it happened, and i how to fix it. But i know these things because i read the message, which fortunately was in a language i understand. Now i would like to handle this exception specially. The COM object threw an HRESULT of 0x800A0CC1 In an ideal world Microsoft would have documented what errors can be returned when i try to access: records.Fields.Items( index ) with an invalid index. But they do not; they most they say is that an error can occur, i.e.: If Item cannot find an object in the collection corresponding to the Index argument, an error occurs. Given that the returned error code is not documented, is it correct to handle a specific return code of `0x800A0CC1' when i'm trying to trap the exception: Item cannot be found in the collection corresponding to the requested name or ordinal ? Since Microsoft didn't document the error code, they technically change it in the future.

• Validation in n-tier asp.net mvc applications

  - by sTodorov

  Dear Stack Overflow gurus, I am looking for some practical/theoretical information regarding best practices for validation in asp.net mvc n-tier applications. I am working on a .Net application divided into the following layers: UI - Mvc3 BLL layer - all business rules. Decoupled from data access and UI layers through interfaces DAL layer - Data access with the repository pattern, EF4 and pocos Now, I am looking for a nice, clean and transparent way to specify my validation rules. Here are some thoughts on the matter so far: UI validation should only be responsible for user input and its validity. BLL validation should be handling the validity of the data regarding the application business rules. My main concern is how to bind the BLL and UI validation in the most efficient way. One think I am would like to avoid is having the UI check in a collection of validation and adding manually errors to the ModelState. Furthermore, I do not want to pass the ModelState to the BLL to be populated in there. I will appreciate any thoughts on the matter. P.S. Should this question be marked as a discussion ?

• Connecting to a network drive programmatically and caching credentials

  - by Chris Doggett

  I'm finally set up to be able to work from home via VPN (using Shrew as a client), and I only have one annoyance. We use some batch files to upload config files to a network drive. Works fine from work, and from my team lead's laptop, but both of those machines are on the domain. My home system is not, and won't be, so when I run the batch file, I get a ton of "invalid drive" errors because I'm not a domain user. The solution I've found so far is to make a batch file with the following: explorer \\MACHINE1 explorer \\MACHINE2 explorer \\MACHINE3 Then manually login to each machine using my domain credentials as they pop up. Unfortunately, there are around 10 machines I may need to use, and it's a pain to keep entering the password if I missed one that a batch file requires. I'm looking into using the answer to this question to make a little C# app that'll take the login info once and login programmatically. Will the authentication be shared automatically with Explorer, or is there anything special I need to do? If it does work, how long are the credentials cached? Is there an app that does something like this automatically? Unfortunately, domain authentication via the VPN isn't an option, according to our admin. EDIT: If there's a way to pass login info to Explorer via the command line, that would be even easier using Ruby and highline.

• C# Taking a element off each time (stack)

  - by Sef

  Greetings, Have a question considering a program that stimulates a stack.(not using any build in stack features or any such) stack2= 1 2 3 4 5 //single dimension array of 5 elements By calling up a method "pop" the stack should look like the following: Basically taking a element off each time the stack is being "called" up again. stack2= 1 2 3 4 0 stack2= 1 2 3 0 0 stack2= 1 2 0 0 0 stack2= 1 0 0 0 0 stack2= 0 0 0 0 0 - for (int i = 1; i <= 6; i++) { number= TryPop(s2); //use number ShowStack(s2, "s2"); } Basically I already have code that fills my array with values (trough a push method). The pop method should basically take the last value and place it on 0. Then calls up the next stack and place the following on 0 (like shown above in stack2). The current pop method that keeps track of the top index (0 elements = 0 top, 1 element = 1 top etc..). Already includes a underflow warning if this goes on 0 or below (which is correct). public int Pop() { if(top <= 0) { throw new Exception("Stack underflow..."); } else { for (int j = tabel.Length - 1; j >= 0; j--) { //...Really not sure what to do here. } } return number; }/*Pop*/ Since in the other class I already have a loop (for loop shown above) that simulates 6 times the s2 stack. (first stack: 1 2 3 4 0, second stack 1 2 3 0 0 and so on.) How exactly do I take a element off each time? Either I have the entire display on 0 or the 0 in the wrong places / out of index errors. Thanks in advance!

• Red5 Unable to Start Distribution.

  - by Iscariot

  I have installed subclipse, Ant, IvyDE, Red5 Plugin for eclipse, All of the Environmental variables are set and the necessary elements have been added to the path. I am attempting to create a Red5 Distribution by using eclipse, opening Build.xml right clicking dist [default] in the outline window and running as and selecting Ant Builder. Eclipse says that the build is Successful. I first stop the Red5 Service, and then I attempt to run the build I create in eclipse it fails, below are the errors that display in the command prompt. I was hoping someone else might have run into a similar issue before.
