Suggestion
Since EJB 20 Spec does not support SQL ANSI datatypes inside ejb-jar.xml, I suggest that Orion accept folowing: accept JavaDoc like tags. So, we can have following: entity description@Data-source jdbc/MySQL @Table-name myOwnTable/description cmp-field persistence-type="varchar(30)" description@Persistence-type varchar(30)/description field-nameuserId/field-name /cmp-field /entity As this sample, Orion should map this entity bean to Datasource and table specified, and the datatype of the fields... Of course, user have choice to write anything inside description/... tags, to maintain compatibility with spec... What you do think about this? My2c Edson Richter

Ops, something wrong, the correct would be: entity description@Data-source jdbc/MySQL @Table-name myOwnTable/description cmp-field description@Persistence-type varchar(30)/description field-nameuserId/field-name /cmp-field /entity -- De: [EMAIL PROTECTED] Para: Orion-Interest [EMAIL PROTECTED] Assunto: Suggestion Data: 06/2/2001 09:11:09 Since EJB 20 Spec does not support SQL ANSI datatypes inside ejb-jar.xml, I suggest that Orion accept folowing: accept JavaDoc like tags.

SUGGESTION: Display nested EJBExceptions ...
EJBException allows for the nesting of exceptions. Since EJBException indicates a system fault, it makes sense to display as much information as possible about it. When my application throws an EJBException, the browser displays a stack trace, but only for the EJBException. Would it not make sense to display the stack trace of the nested exception as well? It would be a simple matter of add the line: exception.getCausedByException().printStackTrace(); somewhere in some file, and it would help a lot.
Re: EJB CMP suggestion
Hello Jen, To find out how to be able to specify joins or any SQL in custom finders, read: http://www.orionserver.com/docs/orion-ejb-jar.xml.html Search for query and look at the partial attribute. What you want is already possible, without changing the code of your beans. Regards, Karl Avedal Jen Hsien Huang wrote: EJB CMP feature is fantasy. But it's use less because I cant do a simple joint on it, so I wonder the benifit of CMP is just a dream. for example I have two EJB , Company and Product, a Product can use Company as it CMP field , but if I want a finder method search the Product by the Company name, that's impossible. So why not define a CMP finder syntax can do a simple joint ? for example public Collection findByCompanyName(String value) throws RemoteException, FinderException; public static final String findByCompanyName_query = "$company.name LIKE $1"; this will generate a SQL call that joint tables of Product and Company. ex "SELECT * from Product , Company where Company.id = Product.company and Company.name LIKE ? " I think this will make CMP more useful.
RE: EJB CMP suggestion
How about having your Product company finder query to be "SELECT * FROM Product WHERE Product.company = (SELECT Company.id FROM Company WHERE Company.name LIKE ?" I understand that this query may not be identical to the query you provided. But my point is it is possible.

Suggestion for classpath problem
Try adding the classpath as a library-path entry in config/server.xml. I had the same problem, and this entry seemed to make all classes in the library-path entries available to all threads initiated (at some level) by OrionServer. -Original Message- From: Ruud Noordermeer [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Date: Friday, January 07, 2000 1:31 AM Subject: Problems with 'ClassPath' and Orion Hey Guys! I'm new to Orion and am trying to get it running on my W95 system. Until now I cannot access classes outside of the orion environment. It looks like the classpath is not correctly set. When I run one of my test servlets which checks the Java VM it tells me only the 'orion.jar' is on my classpath, even though I've used the classpath entries in 'web-application.xml. I'm using: Windows-95 Java JDK 1.2.2 Orion 0.8.2 I've tried: setting classpath in 'default-site/web-application.xml' setting classpath in 'config/web-application.xml' adding -classpath on startup of java - orion server defining a classpath in OS-environment Any suggestions Thanks in advance!
