Installing Apache Archiva as a Web Application

~~TODO: link to wiki location for other application servers

  Archiva can be deployed as a web application into any Java EE application server. This document will show an
  example of doing so with Tomcat 5.5 and Tomcat 6.0.x.

  <<Note>>: When you first start Archiva, you will see an Exception that schema SA does not exist - however it doesn't 
  cause a problem. If you use a username other than 'sa', such as 'archiva', then you seem to get the same error but
  Tomcat fails to start the context and you have to shutdown and restart again.


To deploy Archiva on Tomcat 5.5 and Tomcat 6.0

   * Create a directory in tomcat called archiva, at the same level as bin, conf, logs and the others.

   * Copy the war file into the new directory

   * Create a <<<\<tomcat home\>/conf/Catalina/localhost/archiva.xml>>> file with the following data (replace the database paths with a suitable location). When using
   Tomcat 6.0+, do not include the first line (XML encoding) in the <<<archiva.xml>>> configuration specified below to avoid parsing errors during startup: 

+-------------------------------------------------------------------------+
 <?xml version="1.0" encoding="UTF-8"?>
 <Context path="/archiva"
          docBase="${catalina.home}/archiva/apache-archiva-1.1.war">

 <Resource name="jdbc/users" auth="Container" type="javax.sql.DataSource"
           username="sa"
           password=""
           driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
           url="jdbc:derby:/path/to/database/users;create=true" />

 <Resource name="jdbc/archiva" auth="Container" type="javax.sql.DataSource"
           username="sa"
           password=""
           driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
           url="jdbc:derby:/path/to/database/archiva;create=true" />

 <Resource name="mail/Session" auth="Container"
            type="javax.mail.Session"
            mail.smtp.host="localhost"/>
 </Context>
+-------------------------------------------------------------------------+

   * Install <<<derby-10.1.3.1.jar>>> (or later), <<<activation-1.1.jar>>> and <<<mail-1.4.jar>>> into the Tomcat 5.5 <<<common/lib>>> or Tomcat 6.0 <<<lib>>> directory.
     This is required since the data sources are instantiated before the web application.

   <<Note>>: Tomcat 5.5.20 and 5.5.23 are missing MailSessionFactory and a
   few other classes.  JNDI mail sessions will <not> work.  Use Tomcat 5.5.25
   instead, or see {{{http://issues.apache.org/bugzilla/show_bug.cgi?id=40668}
   Bug 40668}} for a workaround.

   * The ${appserver.base} java property is used by the Archiva internal logging configuration to determine where to output its logs to.
     It is important to define this property either in the $CATALINA_OPTS system environment variable if Tomcat is being launched via the
     command line) or the service properties (if being launched as a service or daemon). The format typically expected is
     -Dappserver.base=<SOMEWHERE>. In this example, we'll put the logs in Tomcat's <<<logs>>> directory so we need to set appserver.base
     property to where Tomcat is installed:

+-----------+
export CATALINA_OPTS="-Dappserver.home=$CATALINA_HOME -Dappserver.base=$CATALINA_HOME" (for UNIX)

OR

set CATALINA_OPTS="-Dappserver.home=%CATALINA_HOME% -Dappserver.base=%CATALINA_HOME%" (for Windows)
+-----------+

   * If setting the ${appserver.base} and ${appserver.home} using the previous step does not work, you can set it in the unpacked Archiva web application's
     <<<WEB-INF/classes/application.properties>>> as follows:

+-----------+
# for Windows:
appserver.base=%CATALINA_HOME%
appserver.base=%CATALINA_BASE%

# or, for UNIX:
appserver.base=$CATALINA_HOME
appserver.home=$CATALINA_BASE
+-----------+

   * When running Tomcat as a <<Windows>> service, you need to edit <<<regedit>>> and then, in
     <<<HKEY_LOCAL_MACHINE \> SOFTWARE \> Apache Software Foundation \> Procrun 2.0 \> TomcatX \> Parameters \> Java>>>, modify
     the <<<Options>>> variable. Set the ${appserver.base} property by adding the following parameters at the end:

+-----------+
-Dappserver.base=%CATALINA_HOME% -Dappserver.home=%CATALINA_HOME%
+-----------+

Archiva Configuration

 Archiva is configured using the <<<~/.m2/archiva.xml>>> configuration file by default when using a Java EE application server. 

~~TODO: how to configure the other file

Upgrading Archiva

  To upgrade the Archiva web application, simply replace the web application with an alternative. Since the database and configuration files are stored
  externally to the application, no further maintainance is needed.

  For general information about upgrading Archiva, see the relevant section in the {{{standalone.html#Upgrading%20Archiva} Installing standalone}} guide.

Configuring and Running Archiva

  Once Archiva is running, it is configured in the same way as the standalone instance. See the {{{../quick-start.html#Setting%20up%20your%20Archiva%20instance} quick start}} guide for more information.
  
Troubleshooting

* Error During Startup

  There are cases when the Tomcat logs only shows the following error during startup:

+-----------+
...
Aug 17, 2009 11:04:02 AM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Aug 17, 2009 11:04:02 AM org.apache.catalina.core.StandardContext start
SEVERE: Context [/archiva] startup failed due to previous errors
Aug 17, 2009 11:04:04 AM org.apache.coyote.http11.Http11BaseProtocol start
...
+-----------+

  One of the common causes for this <<<listenerStart Error>>> is a failure during Spring's initialization. One way to diagnose or confirm the
  exact cause of the error is by adding the following configuration to the unpacked Archiva webapp's <<<WEB-INF/classes/log4j.xml>>>:

+-----------+
<appender name="console" class="org.apache.log4j.ConsoleAppender">
  <layout class="org.apache.log4j.PatternLayout">
    <param name="ConversionPattern" value="%d [%t] %-5p %c %x - %m%n"/>
  </layout>
</appender>

<logger name="org.springframework.web">
  <level value="debug"/>
  <appender-ref ref="console"/>
</logger>
+-----------+

   The above configuration directs Spring's output logs to the Tomcat console and be recorded in Tomcat's log files. 

* Diagnosing Errors

  One of the least decipherable errors you can get from Tomcat is a <<<404>>> when the deployment fails. In <<<\<tomcat home\>/logs/catalina.out>>>  you will only find that it fails, but not why. Also Archiva's logs will not tell you.

  The log messages and stack traces in case of a <<<404>>> can be found in <<<\<tomcat home\>/logs/localhost.\<date\>>>>.
