Got around to writing the deployment scripts that go with the Subversion<\/a> work I did last week. As part of the scripts, I also worked on the problem I wrote about a couple weeks ago<\/a> (ie: needing different log4j properties files per environment). Once you have a source control solution and a master build file, it’s pretty easy. I stripped out the explicit log4j category and appender directives and instead used the Ant <propertyfile><\/code><\/a> tag to write out the appropriate category \/ appender directives based on the presence (or lack thereof) of the project.debug<\/code> property in my build file. When I want to create a build that outputs logging information to the console, this block of code is fired:
\n<target name=\"build.resources.debug\" if=\"project.debug\">
\n  <propertyfile
\n    file=\"WEB-INF\/classes\/log4j.properties\">
\n    <entry key=\"log4j.rootCategory\" value=\"INFO, STDOUT\"\/>
\n  <\/propertyfile>
\n<\/target>
\n<\/code>
\nOtherwise, this block is run:
\n<target name=\"build.resources.production\" unless=\"project.debug\">
\n  <propertyfile
\n    file=\"WEB-INF\/classes\/log4j.properties\">
\n    <entry key=\"log4j.rootCategory\" value=\"ERROR, SMTPAPPENDER\"\/>
\n    <entry key=\"log4j.category.com.mycompany\" value=\"ERROR, SMTPAPPENDER\"\/>
\n  <\/propertyfile>
\n<\/target>
\n<\/code>
\nIn Eclipse, you can easily create the project.debug<\/code> property using the Arguments text box provided in Run –> External Tools –> $your ant build –> Main Tab –> Arguments: -Dproject.debug=true<\/code>. By default then, log4j will only log error conditions and will send them to the SMTP appender. <\/p>\n

The second thing I did was to create a deployment Ant script that wrapped my main build.xml. It checks out the source code from Subversion:
\n<exec executable=\"svn\">
\n  <arg line=\"co svn:\/\/sourcecodeserver\/myproject\/branches\/v1.0 . --username username --password password\"\/>
\n<\/exec>
\n<\/code>, runs the normal build:
\n<ant antfile=\"build.xml\" \/>
\n<\/code>, stops the Tomcat service:
\n<exec executable=\"net\">
\n  <arg line='stop \"Apache Tomcat\"'\/>
\n<\/exec>
\n<\/code>, deletes the existing web application from the Tomcat webapps directory:
\n<delete dir=\"${tomcat.install}myapp\"\/>
\n<\/code>, creates and unpacks the generated war to the Tomcat webapps directory:
\n<mkdir dir=\"${tomcat.install}myapp\"\/>
\n<unzip src=\"myapp.war\" dest=\"${tomcat.install}myapp\"\/>
\n<\/code> and then starts the Tomcat service:
\n<exec executable=\"net\">
\n  <arg line='start \"Apache Tomcat\"'\/>
\n<\/exec>
\n<\/code>
\nWe’ll see how well it works once this goes into production. If nothing else, at least I’ll have a couple more hours in my day.<\/p>\n","protected":false},"excerpt":{"rendered":"
