Hello people, I am new here and would like to tell you about my problem, it turns out that I have a report done in ireport was a project on a program made with language in java, well the issue is that now i need modify it but it turns out that I can't if you want to compile the report. The truth I have already googleado much by internet but I cannot find anything about my problem and I would like to know if I can help. The error generated by ireport is the following: This is not a error of the report in if from my point of view in that when I create a new report without anything inside gives the same error message is most likely that something wrong , as the installation , settings , etc. , if I can help please it would be fantastic. Comments. I am using a translator not speaking English, but that only Spanish. I am sorry if it is that I have not been able to explain the right way.
