That is strange, because
1) org.apache.jasper.JspC has setAddWebXmlMappings(boolean) method, so
it should not fail

2) The jasper call in build.xml (from is on lines 58-62, not on line 67 as
in the message.

1) Can you compare the java source of index_jsp._jspx_meth_sql_query_0
when generated by TCD and the one generated when index.jsp is compiled
at run time?
2) Please create a bugzilla entry.
