Hello friends,
I am trying to develop an application that uses a parser generated by the
Antlr.
In my application source code, I call:
...
MDXLexer lexer = new MDXLexer(...
MDXRecognizer parser = new MDXRecognizer(lexer);
try {
parser.mdx_statement();
}
catch (RecognitionException e) {
e.printStackTrace();
}
catch (TokenStreamException e) {
e.printStackTrace();
}
Thus, sending a erroneous input, a error message will appear:
" line 1:106: unexpected token: null
line 1:106: expecting "FROM", found 'null' "
But, how can I return the error messages for my application? and handling
this message?
thanks for your attention,
best regards
Joel
