Hello,
I have a question regarding an error I get. In a JSP page I use a
regular Java bean. Some properties are set and at the end I call the
bean's create() methode to actually create a new EJB Entity bean.
Creating the EJB fails: I get the error attached to the end of this
message. Now the funny part is that the database contains the new EJB
data. The question I would like to ask you: where to look for the solution?
The code I use in my regular Java access bean:
public void createEJB(){
if (DEBUG) {
System.out.println("FormAccessBean.create() --- entry");
} // end of if (DEBUG)
try{
String jndiName = "stam/Form";
Broker broker = Broker.getInstance();
FormHome formHome = (FormHome)
broker.getHome(jndiName, FormHome.class);
Form form = formHome.create(this.voorletters,
this.tussenvoegsel,
this.naam, this.adres, this.postcode,
this.woonplaats, this.telefoonDag,
this.telefoonAvond, this.geboortedatum,
this.geslacht, this.email, this.groep,
this.vrijeInvoer);
if (DEBUG) {
System.out.println("Form: " + form);
} // end of if (DEBUG)
}
....
}
I have a feeling that my mySQL transaction management is not
configured properly. These are my mySQL settings in jboss.jcml
<!-- JDBC -->
<mbean code="org.jboss.jdbc.JdbcProvider"
name="DefaultDomain:service=JdbcProvider">

name="Drivers">org.hsql.jdbcDriver,org.enhydra.instantdb.jdbc.idbDriver,org.gjt.mm.mysql.Driver</attribute>
</mbean>
<mbean code="org.jboss.jdbc.XADataSourceLoader"

<attribute name="IdleTimeoutEnabled">false</attribute>
<attribute name="LoggingEnabled">false</attribute>
<attribute name="MaxIdleTimeoutPercent">1.0</attribute>
<attribute name="MinSize">0</attribute>
</mbean>
And finally, I've attached the start of the error log messages.
