JRun installation issues

A few extra things must be done to get Opinio to work on JRun. JRun does not follow the servlet spec regarding classloaders, and its own libraries (in $JRUN/lib/) will be loaded before those in opinio/WEB-INF/lib. If these modifications are not done, one might get errors like:

	[1]java.lang.NoClassDefFoundError: org/apache/log4j/Layout
			at org.apache.commons.logging.impl.Log4jFactory.getInstance(Log4jFactory.java:140)
			at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.java:257)
			at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:390)
			at webwork.config.XMLActionConfiguration.(XMLActionConfiguration.java:51)

To remedy this problem, follow these instructions:

Unpack the opinio.war file into a folder.
Delete opinio/WEB-INF/lib/commons-logging*.jar
Move opinio/WEB-INF/lib/log4j-*.jar into $JRUN/servers/lib/ (create this directory if it doesn't exist)
When deploying, deploy from the folder just created, instead of deploying directly from the .war file. We are investigating ways to solve this problem, so that deployment from WAR files will be possible on JRun.
If your server uses another port than 8080, edit the opinio/WEB-INF/opinio.properties file, so that the database URL is correct.
