Can someone please told me where i am wrong? Thank you in advance. Sorry for my bad English

Answer 1

I had the same error in my Maven project after some open dependencies were updated to new versions. In my case they were

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>[1.3.2,)</version>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>[3.0.1,)</version>
</dependency>
<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>eclipselink</artifactId>
    <version>[2.5.0,)</version>
</dependency>

which respectively downloaded

mybatis-spring-2.0.0-SNAPSHOT.jar
mybatis-3.5.0-SNAPSHOT.jar
eclipselink-3.0.0-SNAPSHOT.jar

I searched for the JARs history inside Maven Respository (usually something like {user-home}/.m2/repository ) and found all JARs were update the day I got this error.

I restored the JARs' previous version using "closed" dependencies in my pom.xml , ie:

<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>eclipselink</artifactId>
    <version>**2.5.0**</version>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>**1.3.2**</version>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>**3.4.6**</version>
</dependency>

then update the dependecies. Maven downloaded

mybatis-spring-1.3.2.jar
mybatis-3.4.6.jar
eclipselink-2.5.0.jar

instead, and all worked fine.

Don't even know whether you're using a pom.xml (Maven Project) but of course you're running Tomcat so check if there are some incompatible or recently modified jar versions inside your

{catalina.base}/lib

or you web app

WEB-INF/lib

Hope this helps.
