Hi,
I have an enhancement problem...

******* here is my persisten bean:***************************

public class Bean Serializable{

private String code = null;
private Integer id = null;
private String lb = null;
private List jPages = null;

public String getCode() {
return code;
}

public String getLb() {
return lb;
}

public void setCode(String string) {
if (!string.equals(code)) {
// do something (but anyway continue after if)
}
code = string;
}

public void setLb(String string) {
if (!string.equals(lb)) {
// do something (but anyway continue after if) }
lb = string;
}

public Integer getId() {
return id;
}

public void setId(Integer integer) {
if (!integer.equals(id)) {
// do something (but anyway continue after if) }
id = integer;
}

public List getPages() {
return jPages;
}

public void setPages(List pages) {
jPages = pages;
}

}

*********** here is my mapping file******************************

<hibernate-mapping>
<class name="Bean" table="SWD_TABLE" >
<id name="id" column="J_ID" type="java.lang.Integer">
<generator class="assigned"/>
</id>
<property name="code" column="J_CODE" type="java.lang.String" />
<property name="lb" column="J_LB" type="java.lang.String" />

<list name="jPages" table="PAGE_J" inverse="true" cascade="all" lazy="true">
<key column="J_CODE"/>
<index column="posn"/>
<many-to-many class="PageBean" column="PAGE_ID"/>
</list>
</class>
</hibernate-mapping>


**********I have this message when hibernate starts**************

--------------> do you have any idea of what's going on? and what does this message means?

thanks a lot

public List getJPages() {
return jPages;
}

public void setJPages(List pages) {
jPages = pages;
}

oops, sorry, I made a mistake copying my code.

setJPages and getJPages are correct.

the error is still there and linked to "setCode" (see first message)..

I still don't understand...

It causes NullPointerException, this is not a very big problem, you can ignore this warning, but do not transaform "string" parameter in setter, it will make your object "dirty" after load.

this was the problem!
thankxxx!
