How to remove repeating row in jasper report

There are three ways to compile jrxml to jasper.

1. You can do direct compile via compile button (hammer logo) on iReport designer.

2. You can use ant to compile as shown in the Ant Compile Sample.

   <target name="compile1"> 
     <mkdir dir="./build/reports"/> 
     <jrc 
       srcdir="./reports"
       destdir="./build/reports"
       tempdir="./build/reports"
       keepjava="true"
       xmlvalidation="true">
      <classpath refid="runClasspath"/>
      <include name="**/*.jrxml"/>
     </jrc>
   </target>
   

   Below is the report compile task on my current project.

   

   addition from Daniel Rikowski :

3. You can also use the JasperCompileManager class to compile from your java code.

   JasperCompileManager.compileReportToFile(
                   "our_jasper_template.jrxml", // the path to the jrxml file to compile
                   "our_compiled_template.jasper"); // the path and name we want to save the compiled file to
   

You haven't posted many particulars, but i have ran into a similar issue when dealing with absolute/relative paths with Jasper Report.

There is a known "discomfort" or a bug (if you want to call it that way) with Jasper Report not being able to set or use relative paths to your project resources (subreports, images etc) especially if you are compiling the reports with the IREPORT designer tool.

I am working with jasper report and IREPORT 4.1.1 and every time i compile the JRXML to a .jasper file, my paths are absolute. This causes "havoc" when the whole project is moved to a different machine. In order to use relative paths to my reports i have to compile the reports via programming means i.e in my Java application. In a nutshell, the java utility method i am using reads the JRXML file and substitutes the absolute path with a relative path and then compiles the report.

Take a look at this forum, which has some different answers of how to do it.
