Problemas com data source no WebSphere

Esotu com o seguinte problema: estou fazendo o deploy de uma aplicacao no websphere onde já exite um data source configurado, porem a minha aplicacao nao “encontra” esse data source. Meu log de erros eh segue abaixo.

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jdbc/CondicoesGeraisDS' defined in ServletContext resource [/spring/spring-config-hibernate.xml]: Invocation of init method failed; nested exception is javax.naming.NameNotFoundException: Name  not found in context "java:".

Para consuimir o data souce tenho a seguinte tag em meu web.xml:

 <resource-ref>

       <description>Conexao para o SQL Server</description>

       <res-ref-name>jdbc/CondicoesGeraisDS</res-ref-name>

       <res-type>javax.sql.DataSource</res-type>

       <res-auth>Container</res-auth>

       <res-sharing-scope>Shareable</res-sharing-scope>

 </resource-ref>

No meu spring-config-hibernate.xml tenho:

<bean id="condicoesGeraisDS" class="org.springframework.jndi.JndiObjectFactoryBean">

            <property name="jndiName">

                  <value>java:/comp/env/jdbc/CondicoesGeraisDS</value>

            </property>

      </bean>

abrsss.
