Update / Add records to a csv report

ranjeetkgupta

<p>HI</p><p> </p><p>Just started with BIRTframework. The requirement is quite simple . Have to generate csv reports from a Java standalone program which would produce data (java objects) at regular intervals in a single execution/jvm.</p><p>I am using BIRT java api using the csv emitter plugin to do so using a scripted datasource that points to the class and method that generates data.</p><p> </p><p>The problem is after the first set of data is generated and a csv report is created , the second execution of the report generating program <span class='bbc_underline'><strong>overwrites </strong></span>the existing csv file and not append further data. How can I avoid that ?</p><p>Additional records should be added to the existing csv file everytime the report program is fired.</p><p> </p><p> </p><p>Seems no property is there in CSVRenderOption . Attaching relevant files. Report.executeReport() will be fired every-time, there is some data to report.</p><p> </p><p>Thanks </p><p> </p><p>Ranjeet K Gupta</p><p> </p><p> </p><p> </p><p> </p>

<p>After a quick glance at your code in Report.java you could check to see if csvTest.csv exists.  If it does read the contents into a string.  Then render, add the two and save the new csv.</p>
