Why You Should File Bugs - The Glassfish Case

I used Java EE 6 before its release (at December, 10th) in various projects and needed a server for development, test and deployment :-). Glassfish v3 is the official RI, easy to install server with very good NetBeans and Eclipse integration - so it became the natural choice. I filed some bugs / features requests during the migration and development of my projects.

What really surprised me was the responsiveness of the whole engineering team. It was like chatting - I got a response in few minutes. Sometimes the solution to my problem made into the next nightly build. It is exactly the opposite experience, to what I encountered in projects with closed source application servers and "platinum contracts"

The next surprise was a nice email I got after the release. Most of the bugs were fixed!:

"We've just released GlassFish v3 final, a full Java EE 6 open source app server, and we'd like to thank you for your contribution with the following bug report(s) which were fixed in this release :

     [5674] - EJB 3.1 Extension is Not Visible In Updatetool On Vista

Special thanks to the whole engineering team for be as responsive and honest under pressure - shortly before the actual release and Judy Tang the coordinator of the FishCat program. Her responses had milliseconds latency :-).

Don't take the response time for granted though, it's really part of the deal of being on the bleeding edge and reporting detailed bugs like you do during a period when the development team is particularly responsive. SLA can only be offered as part of a support contract ;)

@Alexis,

it was a special information - I know. But having a support contract is necessary anyway, in case you want to have patches delivered earlier than official releases.

Btw. I had to file some bugs for commercial application servers having a high profile support-contract in place. The experience wasn't comparable at all :-).

The quality of my submissions wasn't always o.k. (lack of time etc.) - but the response was nice and polite.

thanks and happy new year!,

regards,

adam

Hello Mr Adam,

I used your function of search :
public List<Object> findByQuery(Class entityType, Map<String, Object> parameters) throws BGISystemException{
try {
Set<Entry<String, Object>> rawParameters = parameters.entrySet();
Query query = em.createQuery(
"FROM " + entityType.getSimpleName());
for(Entry<String, Object> entry : rawParameters) {
query.setParameter(entry.getKey(), entry.getValue());
}
return query.getResultList();

When i pass to the test of the function like this :
Map<String, Object> param = new HashMap<String, Object>();
param.put("name", "adam");

and i call this function, i have an exception :" org.hibernate.QueryParameterException: could not locate named parameter [private java.lang.String com.bgi.jpa.Customer.name]"
for the attribute "name",
I try to use reflexion to solve this(Customer.class.getDeclaredField("name") but i have this exception :"java.lang.NoSuchFieldException: private java.lang.String com.bgi.jpa.Customer.name"
Customer is my entity ,and i want to acced the name of this entity.
Please help me to solve this exception, i must give the solution in my work.
I want to be one day like you, i like very much your book Real World Java EE Pattern.

Hello Mr Adam,
I want to try this function without a named Query in the entity, it's possible.
