jBoss
After deploying the example http://www.jboss.org/rmh_howto.html (with jBoss
specific modifications) I got the following traceback from the jBoss -
Server:
[JAWS] Create, id is 1
[JAWS] Exists command executing: SELECT COUNT(*) AS Total FROM CABIN WHERE
ID=?
[JAWS] Set parameter: idx=1, jdbcType=INTEGER, value=1
[JAWS] Create command executing: INSERT INTO CABIN
(SHIP_ID,BED_COUNT,ID,NAME,DE
CK_LEVEL) VALUES (?,?,?,?,?)
[JAWS] Set parameter: idx=1, jdbcType=INTEGER, value=0
[JAWS] Set parameter: idx=2, jdbcType=INTEGER, value=0
[JAWS] Set parameter: idx=3, jdbcType=INTEGER, value=1
[JAWS] Set parameter: idx=4, jdbcType=VARCHAR, value=empty
[JAWS] Set parameter: idx=5, jdbcType=INTEGER, value=0
[JAWS] Rows affected = 1
[CabinBean] null
The CabinBean is null, but there is a valid entry in database. Logicaly the
client throughs a NullPointerException:
Exception in thread "main" java.lang.NullPointerException

n Source)

:221)

Whats wrong with that example? What's about a jboss.xml sample file?
