compile error creating .jasper file

2002-09-17 10:55

Please help.

 

I ran "ant clean" against the fonts sample, then "ant javac" to create the sample class file. But, when I run "ant compile" I get the following problem>>>

 

 

C:datadownloadjavareport librariesJasperReportsjasperreports-0.4.0-project

JasperReportsdemosamplesfonts>ant compile

Buildfile: build.xml

 

compile:

Answer: My JAVA_HOME was pointing to "c:jdk1.3.1_04" and needed to be pointing to "c:j2sdk1.4.0_01".
