I encounter a problem after deploying ear files in to jboss(2.4.4 with tomcat 4.0.1). it runs smoothly, yet sometimes it seemly would redeploy all ear files, which resides under 'deploy' folder. I do not know why. Are any possiblely reasons may cause such kind of occasion? that would result in Internal server error when calling url from Apache server (version 1.3.22) because, when request from url, ear files are re-deploying itself. I appreciate any suggestions. thank you very mcuh. btw, jvm version is j2sdk1.4.1_01.
