Error in running a spring batch war file - maven

Question

I have created a spring batch project and created a war file for the same using maven
<modelVersion>4.0.0</modelVersion>
<groupId>com.batch</groupId>
<artifactId>dms-batch-app</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>dms-batch-app Maven Webapp</name>
<url>http://maven.apache.org</url>
<properties>
<jdk.version>1.8</jdk.version>
<spring.version>4.0.6.RELEASE</spring.version>
<spring.batch.version>3.0.7.RELEASE</spring.batch.version>
<quartz.version>1.8.5</quartz.version>
<build>
<finalName>dms-batch-app</finalName>
</build>
I am able to generate a war file but when i deploy on the tomcat server and start the tomcat application it throws the below error

I am connection to a database in the context xml as shown below
<jdbc:initialize-database data-source="dataSource">
<jdbc:script location="org/springframework/batch/core/schema-drop-mysql.sql" />
<jdbc:script location="org/springframework/batch/core/schema-mysql.sql" />
</jdbc:initialize-database>
But as per the error the war is not able to read from the jar file. Also i modified the same and kept the ddl scripts under resources folder , yet the war again goes to pick the ddl scripts from the jar file itself.
Kindly provide a solution to this.
And , what will be a better option , deploying spring batch project as a jar file or as a war file ?
Kindly help.

Try this versions:
<jdbc:script location="/org/springframework/batch/core/schema-drop-mysql.sql" />
<jdbc:script location="/org/springframework/batch/core/schema-mysql.sql" />
<jdbc:script location="classpath:/org/springframework/batch/core/schema-drop-mysql.sql" />
<jdbc:script location="classpath:/org/springframework/batch/core/schema-mysql.sql" />
<jdbc:script location="jar:file:org/springframework/batch/core/schema-drop-mysql.sql" />
<jdbc:script location="jar:file:org/springframework/batch/core/schema-mysql.sql" />
