Hello,
I'm new to Seam and I'm posting from France.
This afternoon, I tried a simple Seam project called test with Eclipse and JBoss Tools.
After the project had been generated by the command New Seam Project, I created a simple table on MySQL Server :
"CREATE TABLE `users` (
`usr_id` int(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`username` varchar(15) COLLATE utf8_unicode_ci NOT NULL,
`name` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
`password` varchar(15) COLLATE utf8_unicode_ci NOT NULL,
PRIMARY KEY (`usr_id`),
UNIQUE KEY `username` (`username`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci"
Then I used the command New Seam Generate Entities and the operation seamed OK and has created :
- Users.page.xml ;
- Users.xhtml ;
- UsersEdit.page.xml ;
- UsersEdit.xhtml ;
- UsersList.page.xml ;
- UsersList.xhtml ;
- Users.java (the entity)
- UsersHome.java
- UsersList.java
I did not touch any code generated and I tried to "BrowseData" / UsersList. Then I had these errors :
"javax.el.ELException: /UsersList.xhtml: Error reading 'resultList' on type org.domain.test.session.UsersList_$$_javassist_seam_2
Caused by: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query
Caused by: org.hibernate.exception.SQLGrammarException: could not execute query
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.users users0_ limit 26' at line 1 "
The last error is interesting !
How can I see the real query sent to MySQL Server ?
Isn't it a bug in the Generate Entities tool ?
Before this test, I tried with a Seam example and with the real database (and more complex of course !) on witch I have to work.
The same errors occured.
I have initiated the same discussion in French on http://www.developpez.net/forums/d970848/java/developpement-web-java/frameworks/jsf/seam/mapping-bdd-incorrect-generate-entities/#post5449934
