If I remember rightly a sealing violation is thrown when you're using a package which is 'sealed' (the manifest specifies that all classes from that package must be loaded from that library). Are you sure you're not trying to load the classes from multiple packages, i.e. have competing libraries in your classpath?

Subject: java.lang.SecurityException: sealing violation
Any idea why I would get this error:
java.lang.SecurityException: sealing violation
when executing the following:
import java.io.*;
import org.apache.fop.apps.*;
import org.w3c.dom.*;
import org.xml.sax.*;
public class testing2 {
public static void main(String[] args) {
Document doc =
XmlUtils.CreateDocument("FILE","E:/test/border.fo");
Driver driver = null;
try {
===> driver = new Driver(new InputSource(new
StringReader("E:/test/border.fo")),
new
FileOutputStream("e:/test/testthis.pdf"));
} catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
}
The error is occuring where the ===> is above.
The error trace is:
java.lang.SecurityException: sealing violation
