Make sure you inject the nodeService in the spring-config files. And please give me some karma points

[mrogers]

What would you expect to see from "this.nodeService.toString()"?

That's a service so at best you will see some gobbledegook spring proxy reference.

Eric thaks for info as you notice I had to put nodeService into module-contex.xml

<bean id="txt2pdf" class="com.atolcd.repo.action.executer.TXT2PDFActionExecuter" parent="action-executer">
      <property name="contentService">
         <ref bean="contentService" />
      </property>
     <property name="nodeService">
         <ref bean="nodeService" />
      </property>
      <property name="fileFolderService">
         <ref bean="fileFolderService" />
      </property>
   </bean>
