Running ACS Java under Resin

1. download Resin from www.caucho.com and install it. Call this directory $RESIN_HOME
2. download or cvs checkout acs-java-4 and put it somewhere. Call this directory $ACS_JAVA.
3. edit your inet/port settings in $RESIN_HOME/conf/resin.conf, and add the following line in the host section:

   <web-app id='/' app-dir="/path/to/acs-java-4"/>
   

   This will map the root URL to ACS Java.
4. change the <jsp> section to disable static encoding:

   <jsp precompile='true' static-encoding='false'/>
   

   Static encoding is an optimization that speeds up JSP output by converting static HTML text in JSPs to static byte arrays, so that charset conversion (two-byte chars to one-byte ints) only has to happen once per string per JVM, rather than every time out.print(something) is called for each page invocation. So

   out.println("this is a string literal");
   

   becomes something like:

   static byte[] _jsp_string_0 = "this is a string literal".getBytes();
   out.write(_jsp_string_0);
   

   But this optimization is implemented in a way that breaks explicit pageContext.pushBody()calls from JSP, which we need to make the templating <property> tag work.
5. Run Resin's httpd.sh in the environment set up by the "run" shell script:

   $ACS_JAVA/run $RESIN_HOME/bin/httpd.sh
