AspectJWeaver with JDK 7 - error - only supported at Java 5 compliance level or above

I came across this problem with an older project - when I switched from jdk6 to jdk7, when the application started I encountered: nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.annotation.AnnotationTransactionAttributeSource#0': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException:   error annotation type patterns are only supported at Java 5 compliance level or above I didn't want a purely maven solution because during development I run the app in Tomcat via the IDE (Intellij IDEA). In the end I just upgraded my aspectjweaver dependency to 1.7.2 (it was 1.5.4) <dependency>    <groupId>org.aspectj</groupId>    <artifactId>aspectjweaver</artifactId>    <version>1.7.2</version> </dependency> Everything seems okay now.

We were using Business Objects 4.0, and probably the most important thing was to get the Java library - download 'SAP Crystal Reports for Java runtime components - Java Reporting Component (JRC)' from http://www.businessobjects.com/campaigns/forms/downloads/crystal/eclipse/datasave.asp There are a lot of samples on the web to look at - you might find something to help here: http://wiki.sdn.sap.com/wiki/display/BOBJ/Java+Reporting+Component++SDK+Samples A good example to start with is “JRC EXPORT REPORT”: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/40d580ce-bd66-2b10-95b0-cc4d3f2dcaef If you have an RPT file, the java to generate the report is relatively simple - : ReportClientDocument reportClie...
