Null Pointer Exception while using Java Compiler API
- by java_geek
MyClass.java:
package test;
public class MyClass {
public void myMethod(){
System.out.println("My Method Called");
}
}
Listing for SimpleCompileTest.java that compiles the MyClass.java file.
SimpleCompileTest.java:
package test;
import javax.tools.*;
public class SimpleCompileTest {
public static void main(String[] args) {
String fileToCompile = "test" + java.io.File.separator +"MyClass.java";
JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
int compilationResult = compiler.run(null, null, null, fileToCompile);
if(compilationResult == 0){
System.out.println("Compilation is successful");
}else{
System.out.println("Compilation Failed");
}
}
}
I am executing the SimpleCompileTest class and getting a NullPointerException. The ToolProvider.getSystemJavaCompiler() is returning null. Can someone tell me what is wrong with the code
