Jasper and Eclipse

Hi!
I tryed to run Jasper Report from Eclipse RCP plugin application, but some problems occured.

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:
C:\NEclipse\classic_1162406069063_403217.java:4: package net.sf.jasperreports.engine does not exist
import net.sf.jasperreports.engine.*;

where C:\NEclipse in the folder where Eclipse is installed.

I use code like this :
Connection conn;
Map parameters = new HashMap();
parameters.put("Title", "Test Article report");
Statement stmt;
try {

try {
Class.forName("org.postgresql.Driver");
}
catch (ClassNotFoundException e1) {
e1.printStackTrace();
}

conn = DriverManager.getConnection("jdbc:postgresql:POS", "user", "pwd");
JasperDesign jasperDesign;
try {
jasperDesign = JasperManager.loadXmlDesign("c:\\classic.jrxml");
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
//JasperReport jasperReport = JasperManager.loadReport("c:\\classic.jasper");
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, conn);
JasperViewer.viewReport(jasperPrint);
} catch (JRException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
stmt.close();
conn.close();
} catch (SQLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

when I try to use compiled report, so do not compile it, I receive
another error:

Unhandled event loop exception
Reason:
net/sf/jasperreports/engine/fill/JRFillParameter

Any ideas how to do it to work (considering that required jars had attached to the RCP application)


I had another test app, which in not eclipse plugin , and from there it works, and shows the report.

So I suppouse that problem is with the setup of compile paths, classpath, eth...
Any Ideas?

"d. m.",

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!
