hi Right now i am facing one more problem. I am using apache2,jboss 1.0.4,suselinux10. I compiled apache and mod_jk file in the same environment suselinux10. Then the connection between between apache and jboss was working fine.The i modified mod_jk.conf and worker.properties file for setting up load balancing between two jboss server. After that i tried to connect apache with jboss the it showed the error---- "STARTING HTTPD2 (PREFORK) HTTPD2-PREFORK: SYNTEX ERROR ON THE LINE 204 OF /ETC/APACHE2/HTTPD.CONF: SYNTEX ERROR ON LINE 3 OF /ETC/APACHE2/MOD_JK.CONF: API MODULE STRUCTURE 'JK-MODULE' IN FILE /USR/LIB/APACHE2/MOD-JK.SO IS GRABLED. PERHAPS THIS IS NOT AN APACHE MODULE DSO?" Then i nullify the changes i made on mod_jk.conf and worker.properties file,but the same error is coming while i am trying to connect apache2 with jboss. Please tell me what to do .this problem is killing me. regards, pranjal deka --------------------------------- Heres a new way to find what you're looking for - Yahoo! Answers
