InvalidPropety on bean

[MmarcoM]

hello all,
i am banging my head against a NotWritablePropertyException in spring
i have a spring-based webapplication in which i am defining a bean with two string propertiess..
here is the code

public class DataSourcePopulator  {
	//~ Instance fields       private DataSource dataSource;
      private int createEntities = 1000;
      private JdbcTemplate template = null;

	  private String[] externalSqlFiles;
	  private SqlScriptParser sqlScriptParser = new SqlScriptParser();


	  private String seedFile="";


      //~ Methods ================================================================

      public void setCreateEntities(int createEntities) {
          this.createEntities = createEntities;
      }

      public int getCreateEntities() {
          return createEntities;
      }

      public void setDataSource(DataSource dataSource) {
          this.dataSource = dataSource;
      }

      public DataSource getDataSource() {
          return dataSource;
      }


      public void setExternalSqlFiles(String[] files) {
		  externalSqlFiles = files;
  	  }


  	  public String[] getExternalSqlFiles() {
		  return externalSqlFiles;
  	  }


	  public void setSeedFile(String file) {
		  seedFile = file;
	  }

	  public String getSeedFile() {
		  return seedFile;
	  }
   ....

and following dataSourcePopulator.xml (which is being loaded at startup in jboss 4.0.2)

<beans>
	<!-- Configurer that replaces ${...} placeholders with values from properties files -->
	<!-- (in this case, mail and JDBC related properties) -->

      <bean id="dataSourcePopulator" 
	           class="com.myapp.backend.util.DataSourcePopulator" init-method="init">
	            
	             <property  name="dataSource">
	      		<ref bean="dataSource"/>
	      	     </property>
	      	     
	      	     
	      	     <property name="externalSqlFiles">
	      	        <list>
	      	           <value>Backend-1.0-schema.sql</value>
	      	        </list>
	      	     </property>
	      	     
	      	     <property  name="seedFile">
		      	  <value>budget-seed.xml</value>
		     </property>
	      	     	      	     
	      	     
         </bean>
    	      
      
</beans>

i can't understand why it is complaining about that property....
it has a public setter and a public getter........

and, a little mistake, i am using spring-1.2.1


thanks in advance and regards
