http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6406 All classes in $CATALINA_HOME/classes become invisible when the Oracle 8.1.7 JDBC driver classes are added to this shared class loader directory. Summary: All classes in $CATALINA_HOME/classes become invisible when the Oracle 8.1.7 JDBC driver classes are added to this shared class loader directory. Product: Tomcat 4 Version: 4.0.2 Final Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Major Priority: Other Component: Jasper AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] All classes in $CATALINA_HOME/classes become invisible when the Oracle 8.1.7 JDBC driver classes are added to this shared class loader directory. This was NOT a problem before j2sdk1.4.0-rc. The Oracle 8.1.7 JDBC driver comes from Oracle packaged in two zip files: classes12.zip and nls_charset12.zip. When these files are unpacked, two directories result: oracle and javax. If these two directories are placed in /WEB-INF/classes, everything works fine. However, if these directories are instead placed in $CATALINA_HOME/classes, then all the classes in the $CATALINA_HOME/classes directory become invisible and the directory itself disappears from the classpath. (i.e., The application context attribute named org.apache.catalina.jsp_classpath no longer includes a reference to $CATALINA_HOME/classes.) It turns out that the javax directory is the key to this problem. If I delete this directory from $CATALINA_HOME/classes, everything works fine again. Luckily, the same classes that Oracle provides in this directory (javax.sql.*) are part of the 1.4 JRE. Nevertheless, this is a nasty problem. The workaround next time will unlikely be so easy. This problem is very easy to duplicate in both the FULL and the LE version of Tomcat 4.0.2. Note: Similar errant results occur when the two Oracle zip files are renamed to jar’s and then placed in the $CATALINA_HOME/lib directory. In this case, however, it seems that only the classes in classes12.jar become invisible, although this was not tested. -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
