Tomcat 3.2.1 servlet load on startup problem
Hi, I have been following the instructions in the tomcat faq to start a servlet whenever tomcat starts, but with no luck, can someone give me a light? When-ever I start tomcat, the console should beam out a message which says "Servlet Loaded" and set a "appServerPath" variable, however, its just simply not load. I can run the servlet manually with no problem, the console will beam out the message, and set that variable here is the context path in the server.xml of tomcat: Context path="/myDir" docBase="C:\myDir" crossContext="true" debug="0" reloadable="true" trusted="false" /Context Here is the web.xml in the C:\myDir\WEB-INF\: which dezscribes the servlet to load: servlet servlet-nameservletInit_newsgroup/servlet-name servlet-classcom.myservlet.servletInit_newsgroup/servlet-class load-on-startup1/load-on-startup /servlet the servlet is located in C:\myDir\WEB-INF\classes\com\myservlet\ am I missing something?

How to access servlets without prefixes

Is this still a bug in 3.2? Well, you have to get into a pedantic discussion of "bug" versus "feature" to decide what's really going on :-) When you are outside the scope of the relevant specifications (as we are here), it can get difficult to know sometimes. To complete the pedantic discussion, the difference between a bug and a feature is that a bug is unintended. I have Tomcat 3.2 installed on a Linux platform, but I find myself having to restart Tomcat whenever I want the jsp to reflect any change in the generated servlet. I have even tried deleting the source and class files in the work directory, but that doesn't work. Does anyone have any ideas on how to correct this? Or do I have to wait for Tomcat 4.0 to be completed. Let's divide this world into at least two sub-worlds: * I changed the JSP source code itself. All JSP engines are required by the specs to recompile the page in this case, and therefore reflect the changes. I've had no problems with this in 3.2 or 4.0. * I changed a bean class used in a JSP page, without updating the JSP page itself. The 3.1 and 3.2 approaches to auto-reloading a web app do not correctly detect all cases of this. The 4.0 approach should do so correctly for classes in WEB-INF/classes (not yet for classes in JAR files under WEB-INF/lib). Under *no* version of Tomcat will you be able to update classes that were loaded via the CLASSPATH, and have them reflected in changed behavior in your web app, without restarting Tomcat. I don't have my JSP files, nor the work directory in my classpath, yet, still, they do not reload without restarting Tomcat. Even if I delete the source and class files in the $TOMCAT_HOME/work directory they still get regenerated from the old JSF source. Is Tomcat caching my JSF file somewhere? If so, how do I get it to stop? By the way, I have my JSF files on a network drive, however, I don't think that the NFS is caching the file, because it sees the new copy when I restart Tomcat, not the NFS. How stable is Tomcat 4.0? Can I install it instead of 3.2 without error? Andreas Sheriff Craig McClanahan

When-ever I start tomcat, the console should beam out a message which says
"Servlet Loaded" and set a "appServerPath" variable, however, its just
simply not load.
I can run the servlet manually with no problem, the console will beam out
the message, and set that variable
here is the context path in the server.xml of tomcat:
Context path="/myDir"
docBase="C:\myDir"
crossContext="true"
debug="0"
reloadable="true"
trusted="false"
/Context
Here is the web.xml in the C:\myDir\WEB-INF\:
which dezscribes the servlet to load:
servlet
servlet-nameservletInit_newsgroup/servlet-name
servlet-classcom.myservlet.servletInit_newsgroup/servlet-class
load-on-startup1/load-on-startup
/servlet
the servlet is located in C:\myDir\WEB-INF\classes\com\myservlet\
am I missing something?
You've got all the configuration stuff right ... the problem is in your servlet.
Your initialization message is generated in the doGet() method, which is only called
when a request actually comes in. If you want to do things when the servlet is first
loaded, place that code in the init() method instead.
Note that init() does not receive a request object (because it is not called as the
result of a request). Therefore, you will need to use some other technique to
initialize your "appServerPath" context attribute. A common technique would be to use
a servlet initialization parameter that is read in the init method:
servlet
servlet-nameservletInit_newsgroup/servlet-name
servlet-classcom.myservlet.servletInit_newsgroup/servlet-class
init-param
param-nameserverPath/param-name
param-valuehttp://www.mycompany.com:8080/param-value
/init-param
load-on-startup1/load-on-startup
/servlet
and then in your servlet:
public void init() throws ServletException() {
String path = getServletConfig().getInitParameter("serverPath");
getServletContext().setAttribute("appServerPath", path);
System.out.println("Servlet loaded");
}
Thanks!

Tomcat 3.2.1 on SCO O/S 5.0.4
I am trying to get Tomcat 3.2.1 running under SCO Openserver 5.0.4. The JSP examples fail with an Error 500. I have seen entries somewhere (the FAQ I believe) that suggest that the problem could be that "jasper.jar" or "tools.jar" are not in the CLASSPATH. The "jasper.jar" file is easy; it is in the Tomcat "lib" subdir; however, the "tools.jar" file is nowhere on my system. I have installed the Sun JRE and the JDK (SCO's version), but still have no "tools.jar". Has someone been here and done this? Thanks, Steve Wyatt

Christian, add the "home" parameter to the Context. This is explained in the the server.xml comments near the Context entries.

[repost] endless loop in jsp
Sorry to repost this question, but I really have no clue. The problem is that java grabs 100% of my CPU in some conditions, when I try to access some jsp files, and I cannot figure how to solve it. Here is the configuration: I am using apache tomcat. I have some virtual hosts, defined like this: VirtualHost 1.2.3.4 ServerAdmin [EMAIL PROTECTED] DocumentRoot /zob ServerName www.zob.com ErrorLog /var/log/httpd-zob.error_log TransferLog /var/log/httpd-zob.access_log ApJServMount /servlets /ROOT/servlets Directory "/zob/*/WEB-INF" Options None Deny from all /Directory /VirtualHost In tomcat.conf, I have: ApJServMount default /root AddType text/jsp .jsp AddHandler jserv-servlet .jsp And in server.xml: Host name="www.zob.com" Context path="/servlets" docBase="/zob/servlets" debug="0" reloadable="true" / /Host The problem is the following: When I access a jsp file in /zob/servlets, it works well. But if I try to access a jsp file somewhere else (for instance /zob/foo.jsp), a java process hangs, and takes 100% of my cpu. The only solution is to kill it and restart tomcat. If I try to access a non existent jsp file in /zob/servlets, I get a (correct) 404 page, but if I try to access a non-existent jsp file somewhere else, tomcat hangs also (100% cpu). The problem is that after tomcat begins looping, it becomes obviously impossible to access any other page :-( Is there something wrong in my configuration?

Hi, unfortunately there was no description of any home attribute. I just found in all Tomcat version I downloaded the following: Ejb name="ejb/EmplRecord" type="Entity" home="com.wombat.empl.EmployeeRecordHome" remote="com.wombat.empl.EmployeeRecord"/ What does it mean, perhaps 'Extended java bean'? But you meant to add the home attribute to the context (the Context-tag?). Host name="cparpart.homeip.net" Context path="" home="??" [ place it here?, for what ] docBase="C:/Eigene Dateien/projects/surakware/htdocs" debug="0" reloadable="true" trusted="true" Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="surakware_access_log." suffix=".txt" pattern="common"/ Logger className="org.apache.catalina.logger.FileLogger" directory="logs" prefix="surakware_log." suffix=".txt" timestamp="true"/ /Context /Host Thanks, Christian. -Ursprüngliche Nachricht- Von: Dave Smith [mailto:[EMAIL PROTECTED]] Gesendet: Samstag, 7.

This is explained in the the server.xml comments near the Context entries. This seems to be required whenever you use a directory as docbase which is not in webapps.
