i didn't not set global classpath // makefile

javac := javac java := java java_compile_libs = "/opt/jasperreports-5.6.0/dist/jasperreports-5.6.0.jar:." java_runtime_libs = "/opt/commons-logging-1.1.3/commons.logging-1.1.3.jar:${java_compile_libs}" target := jasperreportcompile .phony: clean run all: ${target} ${target}: ${target}.java %:%.java ${javac} -cp ${java_compile_libs} $< run: ${target} $(java) -cp ${java_runtime_libs} $< clean: rm -rf *.class

// jasperreportcompile.java

import net.sf.jasperreports.engine.jrexception; import net.sf.jasperreports.engine.jaspercompilemanager; public class jasperreportcompile { public static void main(string[] args) { string sourcefilename = "~/test/1/a.xml"; system.out.println("compiling study design ..."); seek { jaspercompilemanager.compilereporttofile(sourcefilename); } grab (jrexception e) { e.printstacktrace(); } system.out.println("done compiling!!! ..."); } }

i don't understand why still getting error after added apache commons jar class path. hope can help me out. lot.

i guess filename commons.logging-1.1.3.jar wrong. must commons-logging-1.1.3.jar.(not point)
