hi, I'm using JBoss 3.2.4 (EJB CMP 2.0) and MySQL 4.0.17. I have to display a list of records from a database using a JSP, in a friendly way.
An easy solution would be a findAll (CMP) using an EJB QL query like : <ejb-ql>SELECT OBJECT(a) FROM App a</ejb-ql>. The result is a Collection with all the selected records from the database. This way might lead to an OutOfMemoyException because of the great number of records in the database. I'd like to get a Collection from a "SELECT *" like query without loading all the stored elements from the database (a fetch by page in a way, using EJB CMP). It is possible to fetch data from MySQL using the LIMIT clause : 'SELECT ... FROM ... LIMIT start, size', where start is the position of the first database record (eg 0) and size is the size of the page (eg 20). To bad for me I can't use it from a CMP entity because CMP 2.0 can't manage it(Error compiling EJB-QL statement) :(:( Any idea to help me solve this CMP problem is welcome.
