  • Why can't i create a RESTful web service in ejb module?

    - by Nitesh Panchal
    Hello, I am using Netbeans 6.8. I can see an option to create a web service in my independent ejb module but i can't seem to find an option to create a RESTful based web service in my ejb module. Is there any kind of restriction in ejb module that i can only create SOAP based web service and not RESTful? or is it the bug of Netbeans 6.8?

  • OracleDataAdapter returns no rows, but the query string works in SQLDeveloper

    - by belzebu
    visual studion 2008 oracle db 11.1.0.7 oracle client for .NET I have a relatively simple query, that selects the rows from across multiple tables (up to 4) using joins. OracleDataAdapter returns no rows for the only dataset's table, but if I copy and paste that query in SQLDeveloper then I get the desired results. I can get the data from other tables using the adapter with no problem, but it seems like it struggles with the bit longer selection query (string length is ~ 300 (not that much at all)) Connection string for the connection is 100% correct. Any ideas? thank you...

  • VS 2008 debugger: How does it decide what Cassini port to run a web service under?

    - by BDW
    I have a VS 2008 solution that includes a web site and a web service. I'm developing both at once, and it's helpful to be able to debug from one into the other. It occasionally can't find the web service. If I look in the web.config, I find the port number it's looking at is not the port number it auto-runs the service in when I use the debugger. For example, the web.config reference says something like: add key="mynamespace.mywebservice" value="http://localhost:55765/mywebservice.asmx" When I hover over the Cassini port icon, I find that the web service is running in port 55382 (or some other non-55765 port). No wonder it can't find it. Is there a way to enforce that the port number it runs under is the one specified in the web config? And if it's not using the web config port number to figure out where to run it... where does it decide? I know in VS2005, there was a way to specify the port number to use when debugging, but I can't find that anywhere in the web service project in VS 2008. This is really going to cause problems as more developers come on to this project - how can I fix it? Deleting and re-adding the web services to the project fixes it, but I'd literally have to do it a couple times a day, not an ideal solution.

  • .net example of using client certificates in web service call?

    - by Rory
    I'd like to use client certificates to verify the identity of administrative callers to my web service. Then I can issue certificates only to the people I want to call my web service and be pretty sure noone else can call it. This is in a very controlled scenario where only one or two people will get the client certificate, so distribution isn't a hard problem. This article provides a good example of how to call a web service using a client certificate. But how can I check details of the client certificate from within my web service? This old article talks about configuring IIS to do it, but I'd like to do it programmatically within my app. I think? thanks for any suggestions!

  • Getting user data from Active Directory using PL/SQL

    - by David Neale
    I had a discussion today regarding an Oracle procedure I wrote some time ago. I wanted to get 7500 user email addresses from Active Directory using PL/SQL. AD will return a maximum of 1000 rows and the LDAP provider used by Oracle will not support paging. Therefore, my solution was to filter on the last two characters of the sAMAccountName (*00,*01,*02...etc.). This results in 126 queries (100 for account names ending in digits, 26 for those ending in a letter...this was sufficient for my AD setup). The person I was speaking to (it was a job interview by the way) said he could have done it a better way, but he would not tell me what that method was. Could anybody hazard a guess at what this method was?

  • If don't own proprietary database engine, what is best way to convert database to mysql?

    - by John Robertson
    I work for a very small company. I was recently faced with the question of whether there is a good way to convert a proprietary database to a MySQL database without owning the proprietary database engine e.g. if one is given a large oracle database file (or choose your favorite proprietary database engine format), but doesn't have a license for the oracle database engine, is there a good, perfectly reliable way to convert it to a MySQL database format that can be read with the MySQL database engine? My question is very vague as to which proprietary format is the source just because there would be multiple sources and it looks like they would be "various and sundry". My suspicion is that there is no perfectly reliable way, especially for a wide variety of proprietary databases. If there are a few proprietary formats for which this is possible, I would still be interested in knowing, though "various and sundry" is probably the real issue. Minimizing cost, effort and correct conversion are key so I think this is probably is the not possible list. -John

  • Temporary intermediate table

    - by user289429
    In our project to generate massive reports in oracle we use some permanent table to hold intermediate results. For example to generate one report we run few queries and populate the table, at the final step we join the intermediate table with huge application tables. These intermediate tables are cleared for next report run. We have few concerns in performance areas. These intermediate tables are transactional and don't have statistics. Is it good idea to join these with application tables which are partitioned and have up to date statistics. We need these results stored in the intermediate tables to be available across requests from UI hence we are not in a position to use oracle provided temporary tables. Any thoughts on what could be done would be appreciated.

  • How do I design a web service (microsoft) that can be consumed by multiple end points?

    - by Ben McCormack
    My company is planning to implement a solution in multiple applications that will help to validate mailing addresses at the point of data entry. We're using UPS's Extended Address Validation (XAV) web service API to validate the addresses. Our current plan is to build a .NET web service that can be used to communicate between our applications and the UPS API. We have applications in VB6, classic ASP, and .NET 2.0, so we'd like to implement a solution that can be easily consumed by each of these programming environments. What are our (Microsoft) options for designing a web service that can be consumed by multiple clients? In particular, is there a way to design a single web service that can respond with JSON (in case we want to validate our web page using javascript) in addition to XML? I'm new to designing web services and want to make sure we consider all of our options. I've heard terms like asmx, WCF, OData, etc., but I don't know which frameworks will support what we're trying to do and where to start.

  • EF4 POCO Not Updating Navigation Property On Save

    - by Gavin Draper
    I'm using EF4 with POCO objects the 2 tables are as follows Service ServiceID, Name, StatusID Status StatusID, Name The POCO objects look like this Service ServiceID, Status, Name Status StatusID, Name With Status on the Service object being a Navigation Property and of type Status. In my Service Repository I have a save method that takes a service objects attaches it to the context and calls save. This works fine for the service, but if the status for that service has been changed it does not get updated. My Save method looks like this public static void SaveService(Service service) { using (var ctx = Context.CreateContext()) { ctx.AttachModify("Services", service); ctx.AttachTo("Statuses",service.Status); ctx.SaveChanges(); } } The AttachModify method attaches an object to the context and sets it to modified it looks like this public void AttachModify(string entitySetName, object entity) { if (entity != null) { AttachTo(entitySetName, entity); SetModified(entity); } } public void SetModified(object entity) { ObjectStateManager.ChangeObjectState(entity, EntityState.Modified); } If I look at a SQL profile its not even including the navigation property in the update for the service table, it never touches the StatusID. Its driving me crazy. Any idea what I need to do to force the Navigation Property to update?

  • Is there a limit to the number of DataContracts that can be used by a WCF Service?

    - by Chris
    Using WCF3.5SP1, VS2008. Building a WCF service that exposes about 10 service methods. We have defined about 40 [DataContract] types that are used by the service. We now experience that adding an additional [DataContract] type to the project (in the same namespace as the other existing types) does not get properly exposed. The new type is not in the XSD schemas generated with the WSDL. We have gone so far as to copy and rename an existing (and working) type, but it too is not present in the generated WSDL/XSD. We've tried this on two different developer machines, same problem. Is there a limit to the number of types that can exposed as [DataContract] for a Service? per Namespace?

  • no ocijdbc10 in java.library.path

    - by B.Z.B
    Hey all, So I've been plagued by this issue, whenever I try to run my app in eclipse, I get this error. 2011-02-23 09:55:08,388 ERROR (com.xxxxx.services.factory.ServiceInvokerLocal:21) - java.lang.UnsatisfiedLinkError: no ocijdbc10 in java.library.path I've tried following the steps I found here with no luck. I've tried this on a XP VM as well as windows 7 (although in win 7 I get a different error, below) java.lang.UnsatisfiedLinkError: no ocijdbc9 in java.library.path I've made sure my oracle client was ok (by running TOAD) and I also re-added the classes12.jar / ojdbc14.jars to my WEB-INF/lib folder taken directly from my %ORACLE_HOME% folder (also re-added them to the lib path). I've also tried just adding the ojdbc14.jar without the classes12.jar. Any suggestions appreciated. In the XP VM I have my PATH variable set to C:\Program Files\Java\jdk1.6.0_24\bin;C:\ORACLE\product\10.2.0.1\BIN. I'm using Tomcat server 5.0

  • VirtualBox error with Ubuntu virtual machine

    - by user2985363
    I am trying to work on a coding project and cannot open my Ubuntu virtual machine with Oracle VM VirtualBox. I took a snapshot yesterday at about 11, and it was working fine. Several times I closed and reopened it. Today when I tried to open it, I kept getting the error below. Failed to open a session for the virtual machine Ubuntu 12.04 32-bit. VM cannot start because the saved state file 'C:\Users\Tyler\VirtualBox VMs\Ubuntu 12.04 32-bit\Snapshots\2014-01-30T19-59-05-976647800Z.sav' is invalid (VERR_FILE_NOT_FOUND). Deleted the saved state prior to starting the VM. I tried deleting the file as it said, but none of the snapshots would open still. The file is still in my recycling bin. What can I do? Also, I took the 1/31 snapshot today before I deleted the previous one.

  • Should a service layer return view models for an MVC application?

    - by erg39
    Say you have an ASP.NET MVC project and are using a service layer, such as in this contact manager tutorial on the asp.net site: http://www.asp.net/mvc/tutorials/iteration-4-make-the-application-loosely-coupled-cs If you have viewmodels for your views, is the service layer the appropriate place to provide each viewmodel? For instance, in the service layer code sample there is a method public IEnumerable<Contact> ListContacts() { return _repository.ListContacts(); } If instead you wanted a IEnumerable, should it go in the service layer, or is there somewhere else that is the "correct" place? Perhaps more appropriately, if you have a separate viewmodel for each view associated with ContactController, should ContactManagerService have a separate method to return each viewmodel?

  • How to have partial incremental synchronizations based on a GUID?

    - by Gonçalo Veiga
    I need to synchronize an SQL Server database to Oracle through an Oracle Transparent Gateway. The synchronization is performed in batches, so I need to get the next set of data from the point where I left off. The problem I'm having is that the only field I have in the source, to help me, is a GUID. If it were a number I could just order by it, keep the last one processed and restart the process by getting the records which are my recorded number. This won't work with a GUID. Any ideas?

  • PL/SQL exception and Java programs

    - by edwards
    Hi Business logic is coded in pl/sql packages procedures and functions. Java programs call pl/sql packages procedures and functions to do database work. pl/sql programs store exceptions into Oracle tables whenever an exception is raised. How would my java programs get the exceptions since the exception instead of being propagated from pl/sql to java is getting persisted to a oracle table and the procs/functions just return 1 or 0. Sorry folks i should have added this constraint much earlier and avoided this confusion. As with many legacy projects we don't have the freedom to modify the stored procedures.

  • Is a Service Bus a good option to communicate with multiple external servers?

    - by PFreitas
    We are developing an application that communicates, via web services or TCP/IP sockets, with multiple servers (up to 50 different external companies). Basically, the exchanged messages are the same (XML), but depending on the inputs of our application we should call 1 or more external servers. The benefits we would expect of introducing a Service Bus in the architecture would be: 1- Remove the need to manage all point-to-point configurations (all the 50 endpoints); 2- Simplify the communication layer of our application by having only one server to talk to; Is a Service Bus a good architectural option for this scenario? What is the best (simplest) Service Bus for this kind of communication? I read a few MSDN articles on Azure Service Bus Relay, but it didn’t seem to fit our needs. Am I wrong? Thanks for your help.

  • ASP.NET web site running in IIS and hosting WCF service fails to get connections on the TCP server

    - by Salil
    I am using the combination of Silverlight client application along with ASP.NET web site running in IIS and hosting WCF service. This WCF service uses the library that starts a TCP server and and initiates requests to the connected TCP clients when the silverlight client application makes the WCF async requests. When I use this library in a local WPF application, the TCP server is able to receive client connection requests and I can get info from these clients. But when I use the same library from the implementation of the WCF service inside the ASP .NET web site project (+ Silverlight client), the server strangely does not receive any connection requests i.e. when I create TcpListener object and issue a start, nothing happens (nor an exception is generated). My setup is I am using the Ethernet for the Internet and Wi-Fi for the TCP clients. Is the WCF service getting confused because of this? Is there any special WCF settings I should put in for TcpListener.Start to work?
