Subject [jira] Commented: (DERBY-3946) Provide support for using the Derby parser to generate Abstract Syntax Trees
Date Mon, 22 Feb 2010 16:08:27 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12836690#action_12836690

Derby Ciu commented on DERBY-3946:
----------------------------------

Hi Rick,

       not able to run ASTParser.java. As you suggested, I have not applied the derby-3946-01-aa-standaloneParser.diff
patch. But still, when I try placing ASTParser.java in sql.compile or sql.conn packages and
run it, I get similar errors in both cases--

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
	at org.apache.derby.impl.sql.compile.ASTParser.execute(ASTParser.java:85)
	at org.apache.derby.impl.sql.compile.ASTParser.main(ASTParser.java:76)

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
	at org.apache.derby.impl.sql.conn.ASTParser.execute(ASTParser.java:86)
	at org.apache.derby.impl.sql.conn.ASTParser.main(ASTParser.java:77)

Thanks,
Ciu
