Overriding product display service

[Grant Edwards <gr...@gmail.com>]

Hi,

I am trying to override the service that displays products in the 
various categories. I need to change what data is returned, prior to the 
rendering thereof. 
org.ofbiz.product.category.CategoryServices.getCategoryMembers(......), 
seemed like the correct service to override, but the overriding thereof 
has had no effect.

Any help would be appreciated.

Kind regards

Grant Edwards

Jacques, thank for the reply.

I do understand the architecture used by OFBiz, by all accounts my 
question might not have been very clear.

I am attempting to override the getCategoryMembers(.....),  in a 
hot-deploy component that I am writing, take a look at the service 
definition below:

<service name="getProductCategoryMembers" engine="java" 
location="com.gat.search.services.CategoryServices" 
invoke="getCategoryMembers">
        <description>Gets ProductCategoryMembers for the 
category_id</description>
        <attribute name="categoryId" type="String" mode="IN"/>
        <attribute name="category" type="org.ofbiz.entity.GenericValue" 
mode="OUT"/>
        <attribute name="categoryMembers" type="java.util.Collection" 
mode="OUT"/>
    </service>

Within my version of com.gat.search.services.CategoryServices I am 
replacing/overriding the functionality provided by the service 
getProductCategoryMembers. This has all worked fine, and within 
https://localhost:8443/webtools/control/availableServices I can see my 
new service. 
https://localhost:8443/webtools/control/availableServices?constraint=location@com.gat.search.services.CategoryServices




Now getting back to my original question. I need to change what products 
are displayed for any given category. I had assumed that 
replacing/overriding the service called getProductCategoryMembers would 
enable me to do this, but unfortunately I am still seeing the original 
list of products displayed in the category in question.

Is getProductCategoryMembers the correct service to replace/override in 
order to change what products are displayed for a given category ?

Kind regards

Grant Edwards

Maybe I did not understand your question, but here we go :
OFBiz uses a Service Oriented Architecture (SOA). It does not use (only) Plain Old Java Object (POJO). In your case you must 
understand that org.ofbiz.product.category.CategoryServices.getCategoryMembers(......),  is used by the service 
getProductCategoryMembers (in applications/product/servicedef/services_view.xml) and overriding getCategoryMembers can't have no 
effect in this service.

Please have a look at the documentation http://docs.ofbiz.org/display/OFBADMIN/Apache+OFBiz+Getting+Started
http://docs.ofbiz.org/display/OFBADMIN/OFBiz+Documentation+Index
