I have two java envoirment instaled 1.6 and 1.7 2. my default java version is 1.7: Java -version java version "1.7.0_07" Java SE Runtime Environment (build 1.7.0_07-b10) Java HotSpot 64-Bit Server VM (build 23.3-b01, mixed mode) jaspersoft studio instaled like plugin in my eclipse indigo, not like a standalone application, its version is 1.3.1 in the eclipse i have only one jre instaled 1.7 seems that this plugin have default property for java version

yes I understand this, but I dont know which config file (or property?) and more over where this file what I need to change for right showing preview

I have report with ejbql datasource wich entity was build under jdk 1.7, so during preview I have following error "Unsupported major.minor version 51.0". I have same error then I run this report in iReport but I change jdkhome param in ireport.conf and all build successfully. What config I need change in JasperSoft Studio (setup like sepparate eclipse plugin) for building my report(all eclipse enviroment set for jdk 1.7)
