      class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/jsp/"
      p:suffix=".jsp" />




<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="org.postgresql.Driver" />
    <property name="url" value="jdbc:postgresql://localhost:5432/car" />
    <property name="username" value="postgres" />
    <property name="password" value="123" />
</bean>

Was it helpful?

Solution 2

This happened to me for the tomcat6 package on Mint 15. The installation had /usr/share/tomcat6/lib/commons-pool.jar -> ../../java/commons-pool.jar but /usr/share/java/commons-pool.jar -> commons-pool-1.5.6.jar was broken. Copying it from my local Maven repo sudo cp ~/.m2/repository/commons-pool/commons-pool/1.5.6/commons-pool-1.5.6.jar /usr/share/java fixed it for me.

OTHER TIPS

It seems the 'commons-pool' jar is not being deployed. If you are using eclipse, you can check which jars are deployed by going to the project's properties, and clicking Deployment Assembly.

May be your commons-pool-x.x.x.jar is not present in your lib folder in deployed folder this can be solved by copying this jar file in apache-tomcat-7.0.54\lib folder

I too faced some problem, in my repo commons-pool2-2.1.jar is not downloaded properly. we need to download correct jar.
