how to solve compile time errors in jasper reports?

[jani99harsh]

Exception in thread "main" net.sf.jasperreports.engine.JRException:Errors were encountered when compiling report expressions class file:1. java.lang.Integer cannot be resolved or is not a type                value = new java.lang.Integer(1); //$JR_EXPR_ID=0$[/code]

i already added jdt jar files.

list of jdt jar files are given below.

org.eclipse.jdt.core-3.7.1

jdtcore-3.1.0

org.eclipse.jdt.core-3.11.1.v20150902-1521

jasper-compiler-jdt-5.5.9

jtds-1.3.1

jdt-0.15.0

what i am missing ?

[jani99harsh]

only jdt-3.4.2_r894.jar is required. above listed .jar files are not necessary. i add new jasper library but not removed old jar. so please remove old jar first than add latest version of jar.
