First time poster here, I been trying to figure this out but I need to ask for advice. I am on MediaTemple DV 2GB server, running OS CentOS 5.8 (Final), 11.0.9 Update #26, I followed a wiki and successfully installed Tomcat, but when I go to start the service, it never starts. I went ahead and added to the tomcat5.conf file: JAVA_OPTS="-Xms128M -Xmx256M" But when I check the catalina.out log I see this: -sh: line 0: export: ` ': not a valid identifier Invalid maximum heap size: -Xmx256M Could not create the Java virtual machine. Any thoughts to what I might be doing wrong? Or what I need to config for the DV system I am running. Thanks for the feedback.
