servlet load-on-startup/ causes TC 5.0.3 to hang on startup
Tomcat 5.0.3 on W2K hangs on startup whenever I deploy an app whose web.xml has a servlet definition that contains a load-on-startup element, either with or without a number. This happens consistently on my TC installation, which has unpackWARs set to true. Has anyone seen this behavior before?

servlet load-on-startup
Does load-on-startup still work for anyone under 4.1.18? Just wanted to check for now, I'm not sure if it's a problem with jk or with tomcat itself yet. -- Rasputin :: Jack of All Trades - Master of Nuns -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

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? Thanks! servletInit_newsgroup.java

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!
