Jasper Server and Reports

Variable Tricks

Goal Variable Class Calculation Example
All Rows Integer none
use built-in REPORT_COUNT
Specific Fields Integer Count
$F{Field}.contains("RegEx") ? 1 : null
Unique Fields Integer Distinct Count
$F{Field}
Multiple Conditions Integer Count
$F{Field1}.contains("RegEx") && $F{Field2}.matches("Const") ? 1 : null
Unique with Multiple Conditions Integer Distinct Count
($F{Field1} + $F{Field2}).endsWith("Const") ? $F{Field1} : null

Syntax - the '? TRUE : FALSE' conditional statement is shown above. What follows '?' is the output if the first statement is TRUE, if FALSE what follows : is the output.

Count All Rows - the built-in variable REPORT_COUNT is a count of all rows. If data in a column is guaranteed to be unique then this variable will equal the total count.

Specific Fields - the example shows how to use a regular expression to evaluate field contents. The count is incremented by one every time the regular expression finds a match.

Unique Fields - the Distinct Count function outputs the number of unique occurrences. Useful if your dataset has duplicate values.

Multiple Conditions - the example shows how to require both statements to be TRUE (via &&) in order to increment the counter.

Unique with Multiple Conditions - this example is a combination of the previous two. The important operator is that went TRUE the output is the Field that you want Distinct Count to evaluate.

Jasper Server Config

  • Create work folder: /opt/jasper/work
  • Copy Oracle JDBC driver ojdbc5.jar to /opt/jasper/jasperserver/apache-tomcat/common/lib/
  • Copy MS SQL JDBC driver sqljdbc.jar to /opt/jasper/jasperserver/apache-tomcat/common/lib/
  • Create Datasources for all datasources
  • Edit /opt/jasper/jasperserver/jasperctl.sh
    • Add
      --max_allowed_packet=16M

      to 'MYSQL_START'

  • Edit /opt/jasper/jasperserver/apache-tomcat/bin/catalina.sh
    • Add
      CATALINA_OPTS="-Djava.awt.headless=true"

iReports Config

  • Add Oracle JDBC drivers
    • Tools, Options
    • Classpath, add /usr/lib/oracle/{<ver>}/client/lib/ojdbc5.jar
  • Add MS SQL JDBC drivers
    • Tools, Options
    • Classpath, add
      /usr/lib/sqljdbc_<ver>/enu/sqljdbc.jar

Server 500 error

  • Stop jasperserver:
/etc/init.d/jasperserver stop
  • Clear out Tomcat work dir:
rm -rf /opt/jasper/jasperserver/apache-tomcat/work/
  • Restart jasperserver:
/etc/init.d/jasperserver start

Jasper Server Install

  • Download bin file
  • Run bin file as root
    • Install folder = /opt/jasper/jasperserver
    • Use bundled Tomcat
    • Use bundled MySQL
    • Use default ports
    • Install sample reports
    • Install iReport
  • Install Oracle client

iReports Install/Upgrade

  • Installed with Jasper Server
  • Upgrade
    • Untar into /opt/jasper/jasperserver
    • Move symlink from old version to new version
ln -sf /opt/jasper/jasperserver/iReport-New_Ver /opt/jasper/jasperserver/ireport
  • Import settings from old version to new version – Tools, Import Settings
    • Manual method = copy ireport.properties in home directory from old ver to new ver
