Hi, all
I tried to run a small sample using jsci IO to read MathML. I compile
Problem.java
through, but when running, I got following exception :
Exception in thread "main" java.lang.ClassCastException
at JSci.mathml.MathMLDocumentImpl.getDocumentElement(Unknown Source)
at JSci.io.MathMLParser.translateToJSciObjects(Unknown Source)
at Problem.<init>(Problem.java:15)
at Problem.main(Problem.java:24)
And here are the files of message.xml and Problem.java :
<!-- message.xml -->
<?xml version="1.0"?>
<!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN"
"
http://www.w3.org/TR/MathML2/dtd/mathml2.dtd">
<apply>
<power/>
<apply>
<plus/>
<ci> x </ci>
<ci> y </ci>
</apply>
<cn>2</cn>
</apply>
// Problem.java
import JSci.io.*;
public class Problem{
public Problem(){
MathMLParser parser = new MathMLParser();
try {
parser.parse("message.xml");
} catch(Exception e) {
e.printStackTrace();
}
Object parseList[] = parser.translateToJSciObjects();
for( int i=0; i<parseList.length; i++)
{
System.out.println("***");
}
}
public static void main(String[] args){
Problem p = new Problem();
}
}
Any body can give me some help?
Thanks,
Jarry
