Hi Cindy
First of all, you have to manually download the next file "birt-runtime-2_3_2_2.zip", save in {install.home}/lib/birt-runtime-2_3_2_2.zip, then change the value of property ({install.home}build.property) "jBPM.birt.download=false" to "jBPM.birt.download=true ". At the end you must run the task "ant install.reporting.into.jboss"
