Hi, I hope someone can help me to solve this ( the previous threads in the list did not helped me at all ). I am using win2k + Tomcat 4.1.12 I enabled the invoker servlet and i am using "\webapps\ROOT\WEB-INF\classes" to publish my Servlets ( Generated with Genexus ). I am calling this url ( http://leonardo/servlet/hlogin ) and the error i get is this one: P Status 500 - type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: Cannot allocate servlet instance for path /servlet/hlogin at org.apache.catalina.servlets.InvokerServlet.serveRequest(InvokerServlet.java:427) at org.apache.catalina.servlets.InvokerServlet.doGet(InvokerServlet.java:180) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) Thanks in advance, Leonardo Abaco TI - Brazil
Cannot allocate servlet instance for path ...
Hello! It may be a well known problem, but I'm new in working with Tomcat. I've made a simple servlet and I want to run it in Tomcat. The servlet is in the package "simpleServlet" and it is called "SimpleServlet". My directory structure is: \webapps\simpleServlet\WEB-INF\ classes\SimpleServlet.class web.xml After I startup Tomcat and trying to browse with this URL...: http://localhost:8080/simpleServlet/servlet/SimpleServlet ...I get this error message: -- javax.servlet.ServletException: Cannot allocate servlet instance for path /simpleServlet/servlet/SimpleServlet at org.apache.catalina.servlets.InvokerServlet.serveRequest(InvokerServlet.java:419) at org.apache.catalina.servlets.InvokerServlet.doGet(InvokerServlet.java:180) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:243) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:190) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2347) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:180) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:468) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:174) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.connector.http.HttpProcessor.process(HttpProcessor.java:1027) at org.apache.catalina.connector.http.HttpProcessor.run(HttpProcessor.java:1125) at java.lang.Thread.run(Thread.java:479) - I will thank a lot if you can help me.

RE: Cannot allocate servlet instance for path
Found the problem. I am using Windows NT. In NT explorer, "Web-inf" and "WEB-INF" are both displayed as "Web-inf". Only if you right click and see property you can find MS-DOS name which is the actual one. When I installed Tomcat, "examples" webapps had a folder "Web-inf" which is actually "WEB-INF". So I also created same name. Spent almost a day but now I am happy that it is working. -Original Message- From: Annam, Sunil Sent: Tuesday, August 27, 2002 3:23 PM To: [EMAIL PROTECTED] Subject: Cannot allocate servlet instance for path Hi, I was using Tomcat 3.x and now switched to tomcat 4.1.9.
