How to configure the Logger so that the generated ProposalProvider actually logs something? [message #493025]

In the generated ProposalProvider is a Logger:

public class AbstractMyDslProposalProvider extends TerminalsProposalProvider {

private final static Logger logger = Logger.getLogger(AbstractMyDslProposalProvider.class);

public void completeModel_Imports(EObject model, Assignment assignment, ContentAssistContext context, ICompletionProposalAcceptor acceptor) {
if (logger.isDebugEnabled()) {
logger.debug("completeModel_Imports feature '" + assignment.getFeature() + "' terminal '"
+ assignment.getTerminal() + "' cardinality '" + assignment.getCardinality() + "' and prefix '"
+ context.getPrefix() + "'");
}
completeRuleCall(((RuleCall)assignment.getTerminal()), context, acceptor);
}

What do I have to do to actually make it log something?

You have to replace the org.eclipse.xtext.logging fragment (host is
org.apache.log4j) with your own one including a custom log4j.properties.

Is there somewhere an example of that? (I am not familiar with log4j and
might take me some time to figure that out without an example)

The easiest way is to check out the org.eclipse.xtext.logging fragment
from CVS and in the log4j.properties change WARN to DEBUG for the
packages you want to lower the debug level.

There's of course some documentation (incl. examples) on the log4j website.

Cheers,
Sven

Hello Michael,

to change log4j configuration out of Workflow file I wrote this bean:

package net.sf.securejdms.wme;

import org.apache.log4j.xml.DOMConfigurator;

public class Log4JConfigurator {
	public void setXml(String xml) {
		DOMConfigurator.configure(this.getClass().getResource(xml));
	}
}

You have to add a bean declaration into your workflow MWE file :

<workflow>
...
<bean class="net.sf.securejdms.wme.Log4JConfigurator" xml="/workflow/log4j.xml" />
...
</workflow>

My log4j.xml file (layout matches MWE default layout):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd" >
<log4j:configuration>
	<appender name="stdout" class="org.apache.log4j.ConsoleAppender">
		<layout class="org.apache.log4j.PatternLayout">
			<param name="ConversionPattern" value="%-5r[%t] %-5p %-35.35C  - %m%n" />
		</layout>
	</appender>
	<root>
		<level value="INFO" />
		<appender-ref ref="stdout"/>
	</root>
</log4j:configuration>

Here you can change INFO to DEBUG or TRACE to see more output.

Regards,
Boris Brodski
