why is logging not showing in the log file when method is called from a xhtml page?

bhoman Oct 11, 2013 4:24 PM

background:

I have a method that returns a list. the method getNexusMembers()

@Name("nexus.functionManager.manageFunction")

@Scope(ScopeType.CONVERSATION)

public class ManageFunctionAction implements Serializable {

...

	public List<NexusMember> getNexusMembers() {
	log.debug("getNexusMembers");
	System.out.println("getNexusMembers");

	Query query = nexusDatabase.createQuery("SELECT m FROM NexusMember m ORDER BY m.memberId");
	return query.getResultList();

}

<ui:composition xmlns="http://www.w3.org/1999/xhtml"

xmlns:s="http://jboss.org/schema/seam/taglib"

xmlns:ui="http://java.sun.com/jsf/facelets"

xmlns:f="http://java.sun.com/jsf/core"

xmlns:h="http://java.sun.com/jsf/html"

xmlns:rich="http://richfaces.org/rich"

template="/layout/template.xhtml">

<ui:define name="body">

<h:outputText

value="#{nexus.functionManager.manageFunction.pageHeader}" />

</h1>

<h:form id="functionForm">

...

<s:selectItems value="#{myClass.nexusMembers}" var="member" label="#{member.memberId}" noSelectionLabel="" />

...

</h:form>

</ui:define>

</ui:composition>

The situation and question:

My understanding is that inside the s:selectItems the value:myClass.nexusMembers calls the method getNexusMembers. This call works; my page has data loaded. My problem is that when I added a log.debug ( the logging level was set accordingly) or even when I used System.out.println(...) these statements never showed in the server.log (nor in the console).

When I added a line of code to call this method from within the same class, but not from the xhtml, the log statement was displayed in server.log and on the console.

Can someone help me understand why this is so?

thank you

What logging facade are you using?

I am using log4j.

import org.jboss.seam.log.Log;
import org.jboss.seam.annotations.Logger;
...
@Logger
    private Log log;
...
public List<NexusMember> getNexusMembers() {
        log.debug("getNexusMembers");
        System.out.println("getNexusMembers");
        Query query = nexusDatabase.createQuery("SELECT m FROM NexusMember m ORDER BY m.memberId");
        return query.getResultList();
}

when I call this method from another Java method the logs are written. when I call this from xhtml (snippet follows) no logs are created

<s:decorate id="memberField" template="/layout/edit.xhtml">
    <ui:define name="label">Nexus Member</ui:define>
    <h:selectOneMenu id="member" required="true" value="#{currentFunction.nexusMember}">
        <s:selectItems value="#{nexus.functionManager.manageFunction.nexusMembers}" var="member" label="#{member.memberId}" noSelectionLabel="" />
        <f:converter converterId="nexusEntityConverter" />
    </h:selectOneMenu>
</s:decorate>

That seems weird. Do you by chance have a log4j configuration file in your deployment?

yes I do.
it is a log4j.xml file under the project/src directory, along with a log4j.dtd

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

If you're using a build off a 7.1.2+ tag or JBoss EAP 6.x then it's likely picking up that configuration file and configuring logging. You have the root priority set to OFF so if System.out.printx() definitely won't show up. The logger may or may not based on the package name.

The first thing to try is to pass -Dorg.jboss.as.logging.per-deployment=false or remove the log4j.xml file from your deployment. Also make sure you're not including a log4j library in your deployment either.
