No Object named DbProvider is defined

[dabi]

Hi,
I am new to Spring.Net Framework. I am trying out the example: Spring.DataQuickStart.2005. I wrote a web app that would simply invoke the methods on Spring.DataQuickStart and display the results on the browser.
I added the following section to the web.config file of the asp.net web application:
<configuration>
<configSections>
<sectionGroup name="spring">
<section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
<section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core"/>
<section name="parsers" type="Spring.Context.Support.ConfigParsersSectionHandler , Spring.Core" />
</sectionGroup>
</configSections>
<spring>
<parsers>
<parser namespace="http://www.springframework.net/database" type="Spring.Data.DatabaseConfigParser, Spring.Data" schemaLocation="assembly://Spring.Data/Spring.Data/spring-database.xsd"/>
</parsers>
<context>
<resource uri="assembly://Spring.DataQuickStart.Tests/Spring.DataQuickStart.GenericTemplate/ExampleTests.xml"/>
</context>
</spring>
</configuration>

In my code behind when I use the following statement:

IApplicationContext ctx = new XmlApplicationContext("assembly://Spring.DataQuickStart.Tests/Spring.DataQuickStart.GenericTemplate/ExampleTests.xml");

to instantiate the XmlApplicationContext object, it gives me the following error:


Spring.Objects.Factory.NoSuchObjectDefinitionExcep tion: No object named 'dbProvider' is defined : Cannot find definition for object [dbProvider]

I don't know where I am going wrong.
Please help

Thanks

Hi,

There is 2 ways for configuring Spring :

---------------------------------------

Using application configuration files (app.config / web.config) :

<configuration>
<configSections>
<sectionGroup name="spring">
<section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
<section name="objects" type="Spring.Context.Support.DefaultSectionHandler , Spring.Core"/>
<section name="parsers" type="Spring.Context.Support.ConfigParsersSectionH andler, Spring.Core" />
</sectionGroup>
</configSections>

<spring>
<parsers>
<parser type="Spring.Data.DatabaseConfigParser, Spring.Data" />
</parsers>

<context>
<resource uri="myConfiguration.xml"/>
</context>
</spring>
</configuration>

You need to use Spring.Context.ContextRegistry to get the IApplicationContext instance :

IApplicationContext context = ContextRegistry.GetContext();


---------------------------------------

Programmatically :
Using the XmlApplicationContext, but you need to register the namespace parser by the code too :

using Spring.Objects.Factory.Xml;
using Spring.Data;
using Spring.Context;
using Spring.Context.Support;

XmlParserRegistry.RegisterParser(typeof(DatabaseCo nfigParser));
IApplicationContext ctx = new XmlApplicationContext("assembly://Spring.DataQuickStart.Tests/Spring.DataQuickStart.GenericTemplate/ExampleTests.xml");


---------------------------------------

You are mixing both ways to configure, that's why you got the error.

HTH,

Hi dabi,

There is an error in the Spring.DataQuickStart 1.1 M1 example, but you got it now !
See this thread :
