Compiling a class using Java code using process
- by Noona
I have this piece of code that compiles a class called tspClassName, when I compile using this code:
Process compileProc = null;
try {
compileProc = Runtime.getRuntime().exec("javac -classpath ."
+ File.separator + "src" + File.separator
+ File.separator + "generated." + tspClassName + ".java -d ." + File.separator + "bin");
// catch exception
if (compileProc.exitValue() != 0)
{
System.out.println("Compile exit status: "
+ compileProc.exitValue());
System.err.println("Compile error:" +
compileProc.getErrorStream());
it outputs this:
"Compile exit status: 2
Compile error:java.io.FileInputStream@17182c1"
The class tspClassName.java compiles without errors otherwise, so I am guessing it has to do with the path,and in my eclipse project, the tspClassName.java resides in package homework4.generated inside src, is there something wrong with the path that I use in the code?
thanks
