Execute .sql script file using java

A few days back I tried to execute our database scripts file using java in a plain way but I am not sure how good it is? but I am done with my work with no known issues but still I'm thinking is that right way to parse entair .sql file and pass the each line to JDBC API and ask JDBC API to execute that line of SQL? Here it is the method I used...

public boolean executeDBScripts(String aSQLScriptFilePath, Statement stmt) throws
IOException,SQLException {
boolean isScriptExecuted = false;
try {
BufferedReader in = new BufferedReader(new FileReader(aSQLScriptFilePath));
String str;StringBuffer sb = new StringBuffer();
while ((str = in.readLine()) != null) {
sb.append(str + "\n ");
}
in.close();
stmt.executeUpdate(sb.toString());
isScriptExecuted = true;
} catch (Exception e) {
System.err.println("Failed to Execute" + aSQLScriptFilePath +". The error is"+ e.getMessage));
}
return isScriptExecuted;
}
