I've moved JBoss to a folder which has no spaces in it and yet, get the same errors when I try to open my jsp files.
----
I've tried removing the jar files that you've mentioned, but doing so crashes the build when using ant. Is it safe to leave these jars alone for the moment? Can I remove the equivalent jars from the tomcat lib folder?

[JBoss Seam] - seam gen floats (in many meanings ...)
by limousyf
Hello,
I notice a weird stuff about my seam-generated entities.
I have float fields in two of my tables :
Forfait :
| CREATE TABLE `forfait` (
| `forfait_id` int(11) NOT NULL auto_increment,
| `numero_avenant` varchar(60) NOT NULL,
| `numero_commande` varchar(60) default NULL,
| `date_signature` date NOT NULL,
| `montant_total` float default NULL,
| `conditions_generales_id` int(11) NOT NULL,
| `contact_client_id` int(11) default NULL,
| PRIMARY KEY (`forfait_id`),
| KEY `contact_client_id` (`contact_client_id`),
| KEY `conditions_generales_id` (`conditions_generales_id`)
| ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
|
and Regie :
| CREATE TABLE `regie` (
| `regie_id` int(11) NOT NULL auto_increment,
| `numero_avenant` varchar(60) NOT NULL,
| `numero_commande` varchar(60) default NULL,
| `date_signature` date NOT NULL,
| `date_debut` date default NULL,
| `date_fin` date default NULL,
| `descriptif_intervention` text NOT NULL,
| `montant_total` float NOT NULL,
| `tarif_journalier` float default NULL,
| `conditions_generales_id` int(11) NOT NULL,
| `contact_client_id` int(11) default NULL,
| `collaborateur_id` int(11) default NULL,
| PRIMARY KEY (`regie_id`),
| KEY `contrat_cadre_id` (`conditions_generales_id`),
| KEY `contact_client_id` (`contact_client_id`),
| KEY `collaborateur_id` (`collaborateur_id`)
| ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
|
Here's an extract of the entities :
Forfait :
| @Column(name = "montant_total", precision = 12, scale = 0)
| public Float getMontantTotal() {
| return this.montantTotal;
| }
|
and Regie :
| @Column(name = "montant_total", nullable = false, precision = 12, scale = 0)
| @NotNull
| public float getMontantTotal() {
| return this.montantTotal;
| }
|
|
| @Column(name = "tarif_journalier", precision = 12, scale = 0)
| public Float getTarifJournalier() {
| return this.tarifJournalier;
| }
|
My question is: why is this a float and not a Float generated in Regie for the montant_total column ?
The exact same column in Forfait generated a Float.
Is this some kind of bug or did I miss something ?
tarif_journalier in Regie can be NULL so I guess a Float is mandatory here, to handle default NULL value.
But for montant_total I don't get it ...
