</connectionStrings>
the webapp doesn't start at all.
Please help!

I have changed the WCf application app.config and solve the issue-
I have only add bindingConfiguration="myBinding" and change basicHttpBinding to webHttpBinding.
Here is the new code-
<bindings>
<webHttpBinding>
<binding name="myBinding" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" transferMode="Streamed" >
<readerQuotas maxDepth="64" maxArrayLength="2147483647" maxStringContentLength="2147483647"/>
</binding>
</webHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="ForecastREST_API.RESTServiceImplBehavior" name="ForecastREST_API.RestServiceImpl">
<endpoint address="http://localhost:59624/RestServiceImpl.svc" binding="webHttpBinding" contract="ForecastREST_API.IRestServiceImpl" behaviorConfiguration="Web" bindingConfiguration="myBinding">
</identity>
</endpoint>

I'm new with spring security ,
I have made a custom authentication provider to check if the user haw access to the secured page or not via database.
every thing was ok, but when I added <intercept-url pattern="/home" access="isAuthenticated()" /> to security configuration an error occurs !
this is my userService :
public Authentication authenticate(Authentication auth) throws AuthenticationException {
Logger logger = null;
logger = Logger.getLogger(Logger.class.getName());
PropertyConfigurator.configure("src/main/resources/log4j.properties");
ResultSet resultSet = null;
PreparedStatement preparedStatement = null;
Connection connection = null;
name= auth.getName();
pwd=auth.getCredentials().toString();
UsernamePasswordAuthenticationToken ret=null;
String select_auth= "select username,password from users where username=? and password=?";
try {
connection = dataSource1.getConnection();
preparedStatement = connection.prepareStatement(select_auth);
preparedStatement.setString(1,name);
preparedStatement.setString(2,pwd);
resultSet = preparedStatement.executeQuery();
if(resultSet.next()){
logger.info("user <"+name+"> is connected");
ret= new UsernamePasswordAuthenticationToken(name, null);}
else
{
ret= null;
}
} catch (SQLException e) {
logger.error("SQLException: " + e.getMessage());
e.printStackTrace();
}
and this is my seurity-config
<http use-expressions="true" auto-config="true">
<form-login login-page="/login.jsp" default-target-url="/home"
authentication-failure-url="/403" />
<logout logout-success-url="/login" />
<intercept-url pattern="/home" access="isAuthenticated()" />
</http>
could someone help me ,or explain me what's the cause of the problem ?
Thanks in advance.
The problem is related to WCF configuration hell, I have developed a wcf rest server and i will be needing it to use with iPhone and android client. Problem is that my custom configuration i think is not picking up because data larger than 64kb give The remote server returned an error: (400) Bad Request. on client. Here is my code
