[EJB/JBoss] - log4j configuration for different filelogs
by Anna_Lut
In my session bean I use object of Parent class:
| public class Parent{
| protected static Logger log;
|
| public Parent(String log4jCategory){
| log =Logger.getLogger(log4jCategory);
| }
|
| ....
| }
|
| public class ChildA extends Parent {
| ....
| }
|
| public class ChildB extends Parent {
| ....
| }
|
|
|
|
| public class MyBean implements javax.ejb.SessionBean {
| private Parent obj;
| ....
| public void initParentObject(String paramValue){
| if (paramValue.equals("A"))
| obj = new ChildA("CategoryA");
| else
| obj = new ChildB("CategoryB");
| }
| ....
| }
|
|
Is it possible to get log data to diferrent file depending on Child class realization.
Of course, it can be done in such way in log4j.xml:
|
| <appender name="CHILD_A"
| .....
| </appender>
|
| <appender name="CHILD_B"
| .....
| </appender>
|
|
| <category name="mypack.ChildA">
| <appender-ref ref="CHILD_A"/>
| </category>
|
| <category name="mypack.ChildB">
| <appender-ref ref="CHILD_B"/>
| </category>
|
|
But in reallife realization, there are a lot of classes in ChildA and ChildB
from different packs, which has their Loggers and they have to write to the same file. That's why I cannot use many different categories in log4j.xml putting only classpath like "mypack.ChildB"
As I see in wiki "Separating Application Logs", I can use CLFilter:
| <filter class="org.jboss.logging.filter.TCLFilter>
| <param name="AcceptOnMatch" value="true">
| <param name="DeployURL" value="app1.ear">
|
But here I have to put a EAR name// but in my examle - I want to have 2 different logs in same bean.
We use JBOSS 3.2.1

[JBoss Seam] - Re: Seam Design Question
by tony.herstell＠gmail.com
Going back to 1/
I need to initialise the "allocations" and this is generally done by a @Factory.
This causes a stack Overflow...
| @SuppressWarnings("serial")
| @Scope(ScopeType.SESSION)
| @Name("allocations")
| public class Allocations implements Serializable {
|
| private List<Day> indoorArenaDays;
| private List<Day> dressageArenaDays;
| private List<Day> sjArenaDays;
|
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| @Factory(scope=ScopeType.SESSION, value="allocations")
| public void init() {
|
| List<DaySlot> indoorArenaDaySlots = new ArrayList<DaySlot>();
| DaySlot daySlot = new DaySlot();
| daySlot.setBooked(true);
| daySlot.setBooker("Billy");
| daySlot.setBookingId(1l);
| daySlot.setReason(BookingReasonsKind.ONE_HOUR_PRIVATE);
| daySlot.setTitle("This is a test");
| indoorArenaDaySlots.add(daySlot);
|
| Day day = new Day();
| day.setDate(new GregorianCalendar());
| day.setDaySlots(indoorArenaDaySlots);
| indoorArenaDays = new ArrayList<Day>();
| this.indoorArenaDays.add(day);
| }
|
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| public List<Day> getIndoorArenaDays() {
| //init();
| return indoorArenaDays;
| }
|
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| public void setIndoorArenaDays(List<Day> indoorArenaDays) {
| this.indoorArenaDays = indoorArenaDays;
| }
|
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| public List<Day> getDressageArenaDays() {
| return dressageArenaDays;
| }
|
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| public void setDressageArenaDays(List<Day> dressageArenaDays) {
| this.dressageArenaDays = dressageArenaDays;
| }
|
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| public List<Day> getSjArenaDays() {
| return sjArenaDays;
| }
|
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| public void setSjArenaDays(List<Day> sjArenaDays) {
| this.sjArenaDays = sjArenaDays;
| }
|
| }
|
This little class started as a POJO (used by my ResourceAllocationController) as it really didn't need to be a Seam Object (or so I though).... Anyhow now its a fully grown up Seam object.
So... How do I get the Factory to work?
Do I need and Interface and make this a body (impl)?
This is the .xthml that calls it.... (and as such expects allocations to be set up - by the factory).
| <h:panelGrid class="left" id="day_slots_choices" width="20%">
| <rich:dataTable var="eachDayForIndoorArena" value="#{allocations.indoorArenaDays}"
| rendered="#{not empty allocations.indoorArenaDays}">
| <rich:column width="10%">
| <f:facet name="header">
| <h:outputText id="resource_date"
| value="#{messages.allocation_day}" />
| </f:facet>
| <div class="centre">
| <h:outputText value="#{eachDayForIndoorArena.date}">
| <s:convertDateTime type="date" dateStyle="full"/>
| </h:outputText>
| </div>
| </rich:column>
| </rich:dataTable>
| </h:panelGrid>
|
If I hack the getXXX then the init will be called, but then it gets called every time.
CONFUSED....

[JBoss Seam] - Re: <s:selectItems> label and value
by nickarls
"pete.muir(a)jboss.org" wrote : Dan is correct. However 2.0.1 allows you two options to customize the value. If you don't use the entity converter, use the itemValue attribute on s:selectItems. If you do, you need to implement a custom entity loading strategy. I'll blog about that soon.
What do you mean by the "If you don't use the entity converter, use the itemValue attribute on s:selectItems"?
I'm trying to do a case of an entity
| @Entity
| public class User {
| @Id @GeneratedValue
| private Integer id;
| private String code;
| private String name
| ... getters/setters/hashCode/equals
|
and would like to do something like
| <f:selectOneMenu value="#{userBean.user.code}" required="true">
| <s:selectItems
| value=#{userBean.userList}
| var="user"
| label="#{user.name}"
| itemValue="#{user.code}"
| >
| <s:convertEntity/>
| </selectItems>
| </f:selectOneMenu>
|
where userBean.userList is a List
should this be doable (displaying name, selecting code) with convertEntity?
I keep getting "Value is required" on it despite of equals/hashcode...
