Looks like maybe some directory permissions changed or some system changed not allowing access to what Jasper needs
Mike Sabroff Web Services Developer [EMAIL PROTECTED] 920-568-8379 -----Original Message----- From: David Rickard [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 18, 2005 12:03 PM To: users@tomcat.apache.org Subject: JSP Compilation, Jasper class loading, and log4j issues System: Solaris SunOS 5.9 Apache: 2.0.52 Tomcat: 4.1.29 Mod JK: 1.2.6 JDK: 1.4.2.02 We have used the above Apache-Tomcat installation for 1-2 years. Within the last few days, Tomcat has started failing to compile JSPs. When a JSP is modified (even simply touched), Tomcat throws the following error message: org.apache.jasper.JasperException: Unable to compile class for JSP An error occurred at line: -1 in the jsp file: null Generated servlet error: [javac] Compiling 1 source file Tomcat is otherwise behaving normally: unmodified pages load and behave normally. catalina.out is peppered with ClassNotFoundException messages for various jasper classes (org.apache.jasper.runtime.HttpJspBase, org.apache.jasper.runtime.TagHandlerPool, org.apache.jasper.servlet.JspServlet). The first sign of trouble came over the weekend, when the log-roller cron (logadm) started returning the following error messages: log4j:WARN No appenders could be found for logger (org.apache.commons.digester.Digester.sax). log4j:WARN Please initialize the log4j system properly. We do not use log4j in any applications on this server (is it used internally by Tomcat?). I would suspect corruption of the jasper JARs, except there is no sign they've been touched recently; these are the contents of the common/lib directory: -rw-r--r-- 1 root other 45386 Nov 21 2003 activation.jar -rw-r--r-- 1 root other 736810 Nov 21 2003 ant.jar -rw-r--r-- 1 root other 165119 Nov 21 2003 commons-collections.jar -rw-r--r-- 1 root other 100776 Nov 21 2003 commons-dbcp-1.1.jar -rw-r--r-- 1 root other 22327 Nov 21 2003 commons-logging-api.jar -rw-r--r-- 1 root other 39523 Nov 21 2003 commons-pool-1.1.jar -rw-r--r-- 1 root other 183104 Nov 21 2003 jasper-compiler.jar -rw-r--r-- 1 root other 72933 Nov 21 2003 jasper-runtime.jar -rw-r--r-- 1 root other 6727 Nov 21 2003 jdbc2_0-stdext.jar -rw-r--r-- 1 root other 98496 Nov 21 2003 jndi.jar -rw-r--r-- 1 root other 8674 Nov 21 2003 jta.jar -rw-r--r-- 1 root other 280984 Nov 21 2003 mail.jar -rw-r--r-- 1 root other 28520 Nov 21 2003 naming-common.jar -rw-r--r-- 1 root other 18245 Nov 21 2003 naming-factory.jar -rw-r--r-- 1 root other 38836 Nov 21 2003 naming-resources.jar -rw-r--r-- 1 root other 79265 Nov 21 2003 servlet.jar I've compared this directory with other (functioning normally) Tomcat installations here, and no JARs are missing. Any ideas what might be causing this, and how to fix it (short of reinstalling Tomcat)? -- David Rickard Software Engineer TechBooks/GTS Your Single Source Solution!
