Re: [Xdoclet-user] Help me using ValueObjects

[kkaal]

I tried this, but it does not work.

 

Obviously, the CMP interprets the column-name as a SQL column-name and includes this in its statement. I get the result, that RealEstateEntryValue is not a valid column-name in the table.

 

Sorry, I nee another advice.

 

But thanks for your thought anyhow.

I believe you need to indicate that the values are persistent. So try inserting the following tags:
[EMAIL PROTECTED]
* column-name="RealEstateEntryValue"

Thus:
/**
* @ejb.interface-method
[EMAIL PROTECTED]
* column-name="RealEstateEntryValue"
* @ejb.value-object
*/
public abstract RealEstateDataAllValue getRealEstateEntryValue();
/**
* @ejb.interface-method
*/
public abstract void setRealEstateEntryValue( RealEstateDataAllValue par );

You do not need the second @ejb.value-object tag in front of the setter.

BTW I would not use the suffix "Value" for a member variable, because it could confuse other programmers, who might think you are storing a value object. :)

Hi,

I am trying to efficiently use a ValueObject. As I am a 30% newbie, I am pretty sure that I am doing something wrong.

On the object-level, I declare:

...
* @ejb.value-object
* name = "RealEstateDataAll"
* match = "*"
...

That procucet the class for me. Works.

In my CMP bean, I include methods (tried several different declarations):

/**
* @ejb.interface-method
* @ejb.value-object
*/
public abstract RealEstateDataAllValue getRealEstateEntryValue();

/**
* @ejb.interface-method
* @ejb.value-object
*/
public abstract void setRealEstateEntryValue( RealEstateDataAllValue par );

I would expect to get the valueObject out of the getter. But it does not do that.

What else do I have to do, to work with the ValueObject??



Thanks for your help.
