Precompiling JSP pages

PDF

If you decided to go the extra mile and extend JIRA's build process to precompile JSP pages, keep in mind that the "include" directory in the JIRA web application needs to be excluded from precompilation. The reason for this is that the JSP files in the "include" directory are not proper JSP files, but are includes that are only meant to be compiled as part of larger JSP pages.

For example, to exclude the JSP pages in the "include" directory when using Maven use the <exclude> sub-element of the <ant:jspc> task, as shown:

    <ant:path id="jspc.classpath">
      <ant:pathelement location="${tomcat.home}/common/lib/jasper-runtime.jar"/>
      <ant:pathelement location="${tomcat.home}/common/lib/jasper-compiler.jar"/>
      <ant:pathelement location="${tomcat.home}/common/lib/servlet.jar"/>
      <ant:path refid="maven-classpath"/>
      <ant:path refid="maven.dependency.classpath"/>
      <ant:pathelement path="${maven.build.dest}"/>
      <ant:pathelement path="${java.home}/lib/tools.jar"/>
    </ant:path>
    <ant:jspc
      package="${pom.package}.jsp"
      destDir="${jspOutDir}"
      srcdir="${warSource}"
      uriroot="${warSource}"
      uribase="/${pom.artifactId}"
      verbose="2"
      classpathref="jspc.classpath">
      <ant:include name="**/*.jsp"/>
      <ant:exclude name="**/includes/**/*.jsp"/>
    </ant:jspc>
