Migration to JBoss7.2eap from jboss5.1.2eap : java.lang.NoClassDefFoundError: Lorg/apache/commons/dbcp/BasicDataSource

Question

I have migrated my application from jboss5.1.2-eap to jboss-7.2-eapand java6 to java8 but after migration it is starting giving me exception while starting the server.

Caused by: java.lang.NoClassDefFoundError: Lorg/apache/commons/dbcp/BasicDataSource

we have a datasource.xml file present in the classpath of the server, having the following line of code.

<bean id="beanName" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
    <property name="maxActive" value="10"/>

Also we have commons-dbcp-1.2.2.jar present in the classpath but it is not working for jboss-7.2-eap.

Now I am not sure if commons-dbcp-1.2.2.jar is supported by jboss7-eap. as it is present in the classpath of the application(present in the loaded module), but still spring is not able to create the bean for datasource.

Answer 1

I suppose that datasource in Jboss EAP should be placed in standalone.xml configuration file and looks like here:

<datasource jndi-name="java:jboss/datasources/Altis" pool-name="Altis" enabled="true">
  <connection-url>jdbc:oracle:thin:@255.255.255.255:1521:sid</connection-url>
  <driver-class>oracle.jdbc.OracleDriver</driver-class>
  <driver>oracle</driver>
  <security>
    <user-name>username</user-name>
    <password>passwd</password>
  </security>
</datasource>

Answer 2

Given module information in the jboss-deployment-structure.xml inside the WEB-INF directory of the war file.

<jboss-deployment-structure>  
  <deployment>  
    <dependencies>  
     <module name="com.oracle.sql" export="true"/>
     <module name="org.apache.commons.dbcp" export="true"/>       
     </dependencies>  
   </deployment>  
</jboss-deployment-structure>

Also the module directories should also follow the same naming convention as per the availability of your .class files inside the jar, like in my case I have created module org.apache.commons.dbcp as while opening commons-dbcp-1.2.2.jar file, .class files are present inside org/apache/commons/dbcp folder.

Note: In case of multiple modules, you need to identify there dependency if a module is dependent on other and that information will be given inside module.xml file. like

 <module xmlns="urn:jboss:module:1.1" name="org.apache.commons.dbcp">  
   <resources>  
       <resource-root path="commons-dbcp-1.2.2.jar"/>
   </resources>  
   <dependencies>
      <module name="org.apache.commons.pool"/>
      <module name="com.oracle.jdbc.driver"/>
   </dependencies>
 </module>
