How to resolve class references in an external config file for grails war deployment?
I am using Grails开发者_开发知识库 1.3.7. I build a war file & deploy it in tomcat. I have an external groovy configuration file that I use to set up logging. I added some perf4j logging appenders to the declaration, but now the configuration file fails to compile because it cannot resolve the fully-qualified class names.
The code looks like this:
log4j = {
...
// file appender that writes out the URLs of the Google Chart API graphs generated by the performanceGraphAppender
def performanceGraphFileAppender = new org.apache.log4j.FileAppender(
fileName: "log/perfGraphs.log",
layout: pattern(conversionPattern: '%m%n')
)
appender name: 'performanceGraphFileAppender', performanceGraphFileAppender
// this appender creates the Google Chart API graphs
def performanceGraphAppender = new org.perf4j.log4j.GraphingStatisticsAppender(
graphType: 'Mean', // possible options: Mean, Min, Max, StdDev, Count or TPS
tagNamesToGraph: 'tag1,tag2,tag3',
dataPointsPerGraph: 5
)
performanceGraphAppender.addAppender(performanceGraphFileAppender)
appender name: 'performanceGraph', performanceGraphAppender
...
}
and the error message that's written out into the log is this:
script1317679813518843914255.groovy: 38: unable to resolve class org.perf4j.log4j.GraphingStatisticsAppender
@ line 38, column 34.
def performanceGraphAppender = new org.perf4j.log4j.GraphingStatisticsAppender(
The war file I am building contains all the required JARs. Any thoughts on how to get it to resolve the references?
Thanks,

There is a possibility that after deployment, it starts using log4j from tomcat. Take a look at lib
folder, maybe it's contains log4j jars. If that's true - the it uses different classloader, that can't see your perf4j classes.
You can try to put your perf4j jars into tomcat's lib
, probably it can fix this issue
