Deploying Entity Bean

[simteq]

I have a bean for an Individual:

public IndividualPK ejbCreate( String forename,
String surname,
String department,
String administrator,
String controller)
throws CreateException
{
this.forename = forename;
this.middlename = "";
this.surname = surname;
this.department = department;
this.administrator = administrator;
this.budgetController = controller;
username = forename.substring(0,1) +
surname.substring(1);
passwd = username;
userCurrent = "Y";
return null;
}

with a primary key class defined as:

public class IndividualPK implements Serializable
{
public String username;
public IndividualPK(String key)
{
this.username = key;
}
public IndividualPK()
{
}
public String toString()
{
return username.toString();
}
public boolean equals(Object ind )
{
return ((IndividualPK)ind).username.equals(username);
}
}

and an ejb-jar:

Models an Individual
<ejb-name>Individual</ejb-name>
IndividualHome
Individual
<ejb-class>IndividualBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.String</prim-key-class>
False
<cmp-field><field-name>forename</field-name></cmp-field>
<cmp-field><field-name>middlename</field-name></cmp-field>
<cmp-field><field-name>surname</field-name></cmp-field>
<cmp-field><field-name>username</field-name></cmp-field>
<cmp-field><field-name>department</field-name></cmp-field>
<cmp-field><field-name>administrator</field-name></cmp-field>
<cmp-field><field-name>budgetcontroller</field-name></cmp-field>
<cmp-field><field-name>passwd</field-name></cmp-field>
<cmp-field><field-name>usercurrent</field-name></cmp-field>
<primkey-field>username</primkey-field>


However when I try to deploy this to the container I get an error message:
The return type of ejbCreate must be the entity beans primary key type, ANY IDEAS?

This line is wrong:

<prim-key-class>java.lang.String</prim-key-class>


It still won't work because your pk is missing a hashCode method. You must be very very very careful with the implementation of your pk class, or you will get weird error that are almost impossible to debug.

I would recommend that you use a simple pk, like java.lang.String.
