Ik heb een probleem deployment van een bean op JBoss 3.2.4. Ik krijg een DeploymentException met de melding "Parameter class not found: Long". Ik heb alle beans en deployment descriptors nagekegen nagekeken en ik heb wel degelijk "java.lang.Long" gebruikt.

Ik vermoed dat de container niet weet naar welk JDBC-type de klasse Long gemapt moet worden. Google leverde niets op. Mischien staar ik me gewoon blind op iets wat heel simpel is.... Alle suggesties zeer gewaardeerd!

Onderstaande code is de code voor de entity bean. Ik gebruik XDoclet om CMP-klasse, interfaces en deployment descriptors te genereren.

Volgens mij neem je die mapping op in een apart document, ik weet alleen zo niet meer welke. Maandag kan ik het voor je opzoeken als ik weer op kantoor ben.

[edit] ik weet dat wij ook die mapping vastgelegd hebben voor elke DBMS wat we gebruiken.

Kruimeltjes zijn weer op :9

Erhm.. Ik zie in totaal 500 regels code, waarvan 130 regels foutmelding. Ik gok dat er weinig mensen echt zinnen hebben om deze lap door te gaan werken. P&W FAQ - De "quickstart" spreekt immers ook over relevante code. Ik kan me niet voorstellen dat je geisoleerde probleem 370 regels lang is.

Daarom doe ik hem dicht. :)
