Attribute "namespace" must be declared for element type "mapper"

[Marco]

Hi,
after updating from:
mybatis-3.1.0-SNAPSHOT -> mybatis-3.1.0-bundle
mybatis-spring-1.1.0-SNAPSHOT -> mybatis-spring-1.1.0-bundle

I get following exception:

..... Failed to parse config resource: class path resource [com/xxx/
server/mybatis-config.xml]; nested exception is
org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper
Configuration. Cause: org.apache.ibatis.builder.BuilderException:

Here my mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>
<typeAliases>
<!--Define a aliases for easy use of them inside the mapper--
>
<typeAlias type="com.xxx.shared.beans.OrderOverviewBean"
alias="OrderOverviewBean"/>
<typeAlias type="com.xxx.shared.beans.OrderBean"
alias="OrderBean"/>
</typeAliases>
<mappers>
<mapper resource="com/xxx/server/order/persistance/
orderoverview-dao.xml" />
<mapper resource="com/xxx/server/order/persistance/order-
dao.xml" />
</mappers>
</configuration>

I would bet this is not caused by the version change.

Looks that either orderoverview-dao.xml or order-dao.xml lacks the
namespace attribute.

You have won the bet. :-)

The error was in my orderoverview-dao.xml.
Thanks a lot!
