I think that enhancing Axis to use the BeanInfo class would generally be useful.
Why don't you make the changes and we can see about integrating them in the source. It should be straight forward to enhance the Beasnserailzier to check for the BeanInfo class, right? Then you will have a) solved your issue and b) contributed to the project! -- Tom Jordahl Macromedia -----Original Message----- From: Benazech Cédric [mailto:[EMAIL PROTECTED]] Sent: Friday, April 12, 2002 5:51 AM To: '[EMAIL PROTECTED]' Subject: RE: how to choose bean attributes to publish in WSDL Thanks a lot for all your answers. They are very helpful for me. I understand the gain to use wrapper for the beans, but for the project I'm working an, there are a lot of bean (!!) and it would be a hard work to create (and maintain) such a redundancy. To avoid that, my idea is to create a class (extending the ClassRep class) which will have the responsabity to describe javabeans. The behaviour of the class would be to search for the BeanInfo of the bean class and if it exists, to use the JavaBean Introspector (that will ask for the getPropertyDescriptor method) to return the field Vector. The advantage is that I only have to create BeanInfo class for each bean : that's a standard way to describe Beans and the most of the work can be done automaticaly (by using or building tools). The difficult part is that I want AxisServlet to use this class instead of using the default ClassRep. Perhaps, I will have to create a copy of the BeanSerializer/Deserializer that will use my version of ClassRep instead of the Axis one. What do you think of this functionnality ? Then, to extend the debate, don't you think that BeanSerializer should use the java.beans.Introspector to introspect the bean classes ?

For example, Person.java would be PersonWS.java Wrapping has an extra benefit, it provides for a more loosely coupled architecture between your public interface and the internal business logic. There is an added benefit as well because the façade layer allows upgrades to the core logic to be made behind the scene without changing the external contract with your web service clients. /Chris -----Original Message----- From: Benazech Cédric [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 11, 2002 12:46 PM To: '[EMAIL PROTECTED]' Subject: RE: how to choose bean attributes to publish in WSDL thanks for your answer. If I understand correctly, you ask me to delete the getter and setter for the attribute I don't want to see in the WSDL. The problem is that I can not modify the beans : they are parts of a big EJB project (they are parameters and return types of EJB methods). In fact, they contain data I don't want to be written in the SOAP messages (for example, public static attributes, unnecessary data from classes extending the bean, etc ...). So my question is, Is there a way to "list" the attribute of beans to publish in the WSDL and to serialize ? It seems to be an important feature, isn't it ?

But leave the getter and setter methods. I thought the 'ClassRep' has the 'addFields' which will do a 'getDeclaredFields' (i.e. private stuff too) and it will test these to see if 'normal' bean getter and setter fields are present for this field. If so, then the fields vector is updated and the WSDL <sequence> for this <complexType> 'should' be updated. I have not tested this but only reviewed the code but that is the way it appears to behave. I just took the time to try this and it works. chris -----Original Message----- From: Benazech Cédric [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 11, 2002 10:58 AM To: [EMAIL PROTECTED] Subject: how to choose bean attributes to publish in WSDL Hello. Is there a simple way to choose the javabeans' attributes to display in the WSDL. for example, I have this bean : public class Personn { private String name, firstname, surname; public String getName() { return name; } public String getFirstname() { return firstname; } public String getSurname() { return surname; } public void setName(String s) { name = s; } public void setFirstname(String s) { firstname = s; } public void setSurname(String s) { surname = s; } } By default, the generated XML Schema generated in the wsdl is : <complexType name="SMSText"> <sequence> <element name="name" nillable="true" type="xsd:string" /> <element name="firstname" nillable="true" type="xsd:string" /> <element name="surname" nillable="true" type="xsd:string" /> </sequence> </complexType> How can I hide the surname, for example, in order to generate this Schema : <complexType name="SMSText"> <sequence> <element name="name" nillable="true" type="xsd:string" /> <element name="firstname" nillable="true" type="xsd:string" /> </sequence> </complexType> I searched a lot (in the Axis source) and tried several ways : - using a BeanInfo : that didn't work. The BeanSerializer doesn't use the java.bean.Introspector - writing a getAttribute() method in the bean : didn't work. This feature doesn't seems to be used anymore : the method is called in the BeanSerializer.getBeanAttributes(Class, TypeDesc) but getBeanAttributes is not used in the BeanSerializer.writeSchema(Types) which is responsible for the WSDL generation - writing a getTypeDesc() methode in the bean : didn't work. I thaught the TypeDesc was used to describe a class, but It's the ClassRep object that is used to Introspect the Bean classes. I haven't understood what the TypeDesc is used for ... :( The only way I see is to write an other BeanSerializer (hard to do ...) or to extend the addFields(Class) method of ClassRep, but I don't know how to make the AxisServlet use my version of ClassRep for the dynamic generation of the wsdl (with the ?wsdl in the URL). Any help will be greatly appreciated. - Cédric PS : excuse my poor english : I'm French and not used to write English ... ;(
