i am new to jasper reports. i have some how executed the sample jasper reports with ant tool as well as oracle jdeveloper's built-in ant tool. now I have a problem. There is a message in database. it has its own format with the details of a person encoded in it something like.. ||John||&|124,2nd Street|| now the task is to decode the message and get the details of the person and to show it in jasper reports. i know that i have to write a java program to decode it. but how to show the details of the person in the jasper reports ? its quite easy to just retrieve data from the database using the querystring tag in .jrxml. But this seems to be a little bit complex. Please help me
