wrong version 49.0, should be 48.0

[tman]

I downloaded iReport 1.2.4 (windows installer version)and JasperReport 1.2.4 and Java j2sdk1.4.2_12.

I am setting the compiler in iReports to use the tools.jar copied from j2sdk1.4.2_12 and

put in the iReport/lib directory. When I try to compile a new report I get the following error:

cannotÂaccessÂjava.lang.Object badÂclassÂfile:Â

C:ProgramÂFilesJavajre1.5.0_02librt.jar(java/lang/Object.class) classÂfileÂhasÂwrongÂversionÂ49.0,ÂshouldÂbeÂ48.0.

 

I understand the problem arises because there is a conflict between the different java compilers.

I thought all the above applications were compatiable. What needs to be changed so that I

can use Java j2sdk1.4.2_12 with iReports and JasperReports?

Hello

Can you try using tools.jar from JDK 1.5?

Our application is designed using the JDK 1.4.2_12 so I'm trying to avoid going to JDK 1.5.

I guess my question is which application is using the JDK 1.5 libraries, iReport 1.2.4. or Jasperreport 1.2.4. I assume the tools.jar for JDK 1.4.2_12 is version 1.4.2...

 

I guess I could investigate further, I just thought someone else has probably already had the same issue.
