Hi, I need to create a report in IReport that uses a Hibernate connection. To do this, I use a basic hibernate pojo which I've verified in a java appliation. I added this pojo, as well as multiple hibernate jars to my ireport classpath: * ojdbc14.jar * hibernate3.jar * ant-1.6.5.jar * antlr-2.7.6rc1.jar * asm-attrs.jar * asm.jar * cglib-2.1.3.jar * dom4j-1.6.1.jar * ehcache-1.1.jar * jdbc2_0-stdext.jar After adding the jars, I successfully created and tested a Hibernate connection (Data->Connections/Data Sources). After verifying the Hibernate connection, I tried creating a report using the report wizard. In the first dialog of the report wizard, I select my DorHibernate data source, enter the HQL query then click next. Then, a popup occurs that says: General problem: Cannot open connection Check your user name and password. Be sure the DMBS is running. I'm sure I can connect using my hibernate pojo because I tested it in my java application. So, I did further research by running filemon. I found that ireport could not find "orghibernateeventSessionEventListenerConfigBeanInfo.class". Also, I researched the web, this forum, and even bought the Ireport manual and couldn't find an answer why I cannot connect. Has anyone ever successfully connected to a Hibernate connection in IReport with this configuration? Hibernate 3 IReport 1.3.1 Oracle 10 thin client If so, do you have a tutorial, which I cannot find anwyhere? What Hibernate version does Ireport use?
