Tomcat4 manager application

[Marco Bucciarelli]

I am using Tomcat4 and I experienced a problem similar to Guy Geens' (http://www.mail-archive.com/debian-java@lists.debian.org/msg01356.html), but the problem comes only accessing to Tomcat trough Apache (using mod_webapp). I used Tomcat 4.0.3 and I had no problem. Now, with Tomcat4.1.12, I have this strange behaviour:   - using the manager application through the Coyote HTTP/1.1 Connector on port 8080 I have no problem; - using the manager application through Apache web server, using the WarpConnector on port 8008 (using mod_webapp), after giving the user and password to autenticate myself on the manager context, I get this exception:   HTTP Status 500 - Internal Server Error   --------------------------------------------------------------------------------   type Exception report   message Internal Server Error   description The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request.   exception   javax.servlet.ServletException: Error allocating a servlet instance  at org.apache.catalina.core.StandardWrapper.allocate(Unknown Source)  at org.apache.catalina.core.StandardWrapperValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source)  at org.apache.catalina.core.ContainerBase.invoke(Unknown Source)  at org.apache.catalina.core.StandardContextValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.authenticator.AuthenticatorBase.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source)  at org.apache.catalina.core.ContainerBase.invoke(Unknown Source)  at org.apache.catalina.core.StandardContext.invoke(Unknown Source)  at org.apache.catalina.core.StandardHostValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.valves.ErrorDispatcherValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.valves.ErrorReportValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source)  at org.apache.catalina.core.ContainerBase.invoke(Unknown Source)  at org.apache.catalina.core.StandardEngineValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source)  at org.apache.catalina.core.ContainerBase.invoke(Unknown Source)  at org.apache.catalina.connector.warp.WarpRequestHandler.handle(Unknown Source)  at org.apache.catalina.connector.warp.WarpConnection.run(Unknown Source)  at java.lang.Thread.run(Thread.java:484)   root cause   java.lang.SecurityException: Servlet of class org.apache.catalina.servlets.ManagerServlet is privileged and cannot be loaded by this web application  at org.apache.catalina.core.StandardWrapper.loadServlet(Unknown Source)  at org.apache.catalina.core.StandardWrapper.allocate(Unknown Source)  at org.apache.catalina.core.StandardWrapperValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source)  at org.apache.catalina.core.ContainerBase.invoke(Unknown Source)  at org.apache.catalina.core.StandardContextValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.authenticator.AuthenticatorBase.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source)  at org.apache.catalina.core.ContainerBase.invoke(Unknown Source)  at org.apache.catalina.core.StandardContext.invoke(Unknown Source)  at org.apache.catalina.core.StandardHostValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.valves.ErrorDispatcherValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.valves.ErrorReportValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source)  at org.apache.catalina.core.ContainerBase.invoke(Unknown Source)  at org.apache.catalina.core.StandardEngineValve.invoke(Unknown Source)  at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(Unknown Source)  at org.apache.catalina.core.StandardPipeline.invoke(Unknown Source)  at org.apache.catalina.core.ContainerBase.invoke(Unknown Source)  at org.apache.catalina.connector.warp.WarpRequestHandler.handle(Unknown Source)  at org.apache.catalina.connector.warp.WarpConnection.run(Unknown Source)  at java.lang.Thread.run(Thread.java:484)   --------------------------------------------------------------------------------   Apache Tomcat   All other non-restricted applications work correctly (jsp and servlets). I did not make particular changes on the original configuration files of Tomcat.   At the end of the file httpd.conf I added this lines:   WebAppConnection        conn            warp    localhost:8008 WebAppDeploy            ../server/webapps/manager         conn    /manager/ WebAppDeploy            marcotest       conn    /marcotest/ WebAppInfo              /webapp-info   I tried to: - move the manager directory from <TOMCAT_HOME>/server/webapps/manager to <TOMCAT_HOME>/webapps/manager, inserting in httpd.conf aline like this: WebAppDeploy            manager         conn    /manager/ - move the configuration of the context from file <TOMCAT_HOME>/webapps/manager.xml into the <TOMCAT_HOME>/conf/server.xml file (inside the <Host> tag) - all combinations of the two.   I also tried to add restrictions to another web application and that works!! This is the example: In server.xml:         <!-- Tomcat MARCOTEST Context -->         <Context path="/marcotest" docBase="marcotest" debug="0"                  reloadable="true" crossContext="false">           <Logger className="org.apache.catalina.logger.FileLogger"                      prefix="marcotest." suffix=".log"                      timestamp="true"/>         </Context>   In web.xml of marcotest application:   <!-- Define a Security Constraint on this Application -->   <security-constraint>     <web-resource-collection>       <web-resource-name>Entire Application</web-resource-name>       <url-pattern>/*</url-pattern>     </web-resource-collection>     <auth-constraint>        <!-- NOTE:  This role is not present in the default users file -->        <role-name>manager</role-name>     </auth-constraint>   </security-constraint>     <!-- Define the Login Configuration for this Application -->   <login-config>     <auth-method>BASIC</auth-method>     <realm-name>Marcotest Application</realm-name>   </login-config>     <!-- Security roles referenced by this web application -->   <security-role>     <description>       The role that is required to log in to the Marcotest Application     </description>     <role-name>manager</role-name>   </security-role>   I am not able to understand! In production I want to activate only the WarpConnector, so I want to use the manager application via Apache.   Thank you, Bye.   Marco.
