Context started twice
There was a thread on this
"http://www.nabble.com/Context-starts-twice-t1351694.html". But my
configuration is a bit different.
this is my configuration:
server.xml doesn't have context definition.
context.xml is empty except this line
<WatchedResource>WEB-INF/web.xml</WatchedResource>
under $CATALINA_HOME/Catalina/localhost, I defined a context xml file,
trip.xml
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="d:/dev/trip/main/build" path="/trip">
<Resource name="jdbc/trip" auth="Container"
..........
</Context>
In my web.xml, I have the following entry,
<servlet>
<servlet-name>dummy</servlet-name>
<servlet-class>com.trip.view.DummyServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
When DummyServlet starts, it init twice. Any help is appreciated.

Nabble has nothing to do with it - it's merely a web-based GUI for
several mailing lists, including Tomcat-user. My personal preference
for a searchable Tomcat mailing list is:
http://marc.info/?l=tomcat-user

All my mistake. I apologize for my stupidity. It turns out it wasn't invoked
twice. It just prints twice. I had the following in log4j.properties.
log4j.rootLogger=ERROR, TRIP
log4j.logger.org.hibernate=WARN, TRIP
log4j.logger.net.sf.hibernate=INFO, TRIP
log4j.logger.com.cutetrip=DEBUG, TRIP
I commented out log4j.rootLogger and it prints only one init now.
Thanks for your help. This is my first time using nabble.com and surprised
to see how prompt I can get response. Thanks again.

Re: Context started twice
Posted by Rashmi Rubdi <ra...@gmail.com>.
I tested your code, the init is called exactly once, when Tomcat starts.
Try one of these:
1) Change
log.info("TestServlet init");
log.info("TestServlet destroy");
to something else like
log.info("TestServlet init ############## ");
log.info("TestServlet destroy ##############");
Re-compile, re-start TC if necessary and
check if you see 2 different outputs on the console.
2) If you see the same output twice, that is if you see
log.info("TestServlet init ############## ");
log.info("TestServlet init ############## ");
log.info("TestServlet destroy ##############");
log.info("TestServlet destroy ##############");
then check web.xml if the same Servlet is defined twice under
different names.
3) Globally search for "TestServlet init" and see if it appears in
more than one Servlet that may be visible to the current installation
of Tomcat.

Do a global search on your projects and also on C: or Home drive to
see if this line of code is defined in an additional Servlet that is
visible to the current installation of Tomcat:
log.info("TestServlet init");
I know you mentioned that there's only one Servlet under webapps, but
just in case...
I also see super.init(config); but that shouldn't cause the
TestServlet's init method to be called twice.

Re: Context started twice
Posted by sc <so...@hotmail.com>.
As you suggested, I started from scratch. I downloaded tomcat 6 from
apache.org. changed $catalina_home to point to the new directory. Under
$catalina_home/webapps, I created a new folder, which only has one servlet
TestServlet
public class TestServlet extends HttpServlet
{
private Log log = LogFactory.getLog(this.getClass().getName());
//public void init() throws ServletException
public void init(ServletConfig config) throws ServletException
{
super.init(config);
log.info("TestServlet init");
}
public void destroy()
{
log.info("TestServlet destroy");
}
}
My web.xml as following:
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd"
version="2.5">
<display-name>Hello, World Application</display-name>
<description>
This is a simple web application with a source code organization
based on the recommendations of the Application Developer's Guide.
</description>
<servlet>
<servlet-name>test</servlet-name>
<servlet-class>com.trip.view.TestServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>test</servlet-name>
<url-pattern>/test</url-pattern>
</servlet-mapping>
</web-app>
I didn't do any changes to the new installation of tomcat. Then I started
tomcat and shutdown it.
The log showed the following entries:
2007-04-30 12:35:27,968 [main] INFO com.cutetrip.view.TestServlet -
TestServlet init
2007-04-30 12:35:27,968 [main] INFO com.cutetrip.view.TestServlet -
TestServlet init
2007-04-30 12:35:40,046 [main] INFO com.cutetrip.view.TestServlet -
TestServlet destroy
2007-04-30 12:35:40,046 [main] INFO com.cutetrip.view.TestServlet -
TestServlet destroy
Since I just downloaded Tomcat, it is likely the double init is caused by my
application or local environment setting. Anywhere I should look at? I am
very puzzled.
Thanks.

Please ignore my previous post.
Sorry, when you mentioned context.xml I was thinking of the one
located under the project's META-INF folder.
Chuck is right, there's no need to move the contents of the
conf/context.xml file anywhere.
Whenever configuration gets messed up (happens very rarely), I
normally start with a fresh install of the zip version of Tomcat after
backing up the existing version. This process normally fixes my
problems quickly with little effort.

Note the following from the 5.5 doc:
"An important consequence for Tomcat 5.5 is that the <Logger> element
found in previous versions to create a localhost_log is no longer a
valid nested element of <Context>."
To see how to set up app-specific loging, look at:
http://tomcat.apache.org/tomcat-5.5-doc/logging.html
Don't know if this has anything to do with the double init(), but some
erroneous <Context> entries have been known to result in erratic app
behavior.

I tried as you suggested. But didn't work. I have cleaned up tomcat
deployment directories and currently the configuration is very simple.
Under $CATALINA_HOME/webapps, there is only one directory ROOT.
Under $CATALINA_HOME/Catalina, there is only one directory "localhost",
which in turn only contains 1 file trip.xml
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="d:/dev/trip/main/build">
<Resource name="jdbc/trip" auth="Container"
type="javax.sql.DataSource"

driverClassName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
url="jdbc:microsoft:sqlserver://localhost:1433;databaseName=trip"
maxActive="8"
maxIdle="4"/>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<!-- Note: as suggested, I have moved the above entry from context.xml over
here. -->
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="local_cutetrip." suffix=".log"
timestamp="true"/>
</Context>
$CATALINA_HOME/conf/server.xml is as following:

The OP doesn't have a META-INF/context.xml file; the one being talked
about is the global one in conf/context.xml, which applies to all
deployed apps. Moving the <WatchedResource> element is unnecessary.
Creating a META-INF/context.xml is useless, since the
conf/Catalina/localhost/trip.xml will override it.
None of which explains why the init() method of the servlet in question
is being called twice. Is there another copy of the trip application
deployed under Tomcat's webapps directory?

Re: Context started twice
Posted by Martin Gainty <mg...@hotmail.com>.
You should not need both
http://tomcat.apache.org/tomcat-5.5-doc/config/context.html
The definition of path
path = The context path of this web application, which is matched against
the beginning of each request URI to select the appropriate web application
for processing. All of the context paths within a particular Host must be
unique. If you specify a context path of an empty string (""), you are
defining the default web application for this Host, which will process all
requests not assigned to other Contexts. The value of this field must NOT be
set except when statically defining a Context in server.xml, as it will be
inferred from the filenames used for either the .xml context file or the
docBase.
The definition of docBase
docBase = The Document Base (also known as the Context Root) directory for
this web application, or the pathname to the web application archive file
(if this web application is being executed directly from the WAR file). You
may specify an absolute pathname for this directory or WAR file, or a
pathname that is relative to the appBase directory of the owning Host.
If a symbolic link is used for docBase then changes to the symbolic link
will only be effective after a Tomcat restart or by undeploying and
redeploying the conext. A context reload is not sufficient.
Do not choose a docBase that starts with your Host's appBase string. The
default appBase is "webapps" so do not choose a docBase like "webapps-foo."
Doing so will lead to deployment errors: see Bugzilla for details.

There was a thread on this
"http://www.nabble.com/Context-starts-twice-t1351694.html". But my
configuration is a bit different.
this is my configuration:
server.xml doesn't have context definition.
context.xml is empty except this line
<WatchedResource>WEB-INF/web.xml</WatchedResource>
under $CATALINA_HOME/Catalina/localhost, I defined a context xml file,
trip.xml
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="d:/dev/trip/main/build" path="/trip">
<Resource name="jdbc/trip" auth="Container"
..........
</Context>
In my web.xml, I have the following entry,
<servlet>
<servlet-name>dummy</servlet-name>
<servlet-class>com.trip.view.DummyServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
When DummyServlet starts, it init twice. Any help is appreciated.
