Could you please elaborate the "problem" between apache and jboss? Error message posted looks like MSSQL connectivity issue. As described in manual, the possible config errors can be in (clustered or not) a) APACHE_HOME/conf/mod-jk.conf b) conf/workers.properties c) conf/uriworkermap.properties d) jbossweb-tomcat50.sar/server.xml e) jbossweb-tomcat50.sar/META-INF/jboss-service.xml My 2 cents.
