Hi,
I have just downloaded the DBTags taglibrary. After a quick look
I have two questions:
1) Why do all the attributes of the tags have "rtexpvalue" set to false?
By having rtexpvalue, column names or numbers can be variables in a
java class or interface and jspc can catch any errors before deployment.
eg:
<dbtags:getTime colName='<%=Constants.START_DATE%>' format="EEE, dd
MM yyyy"/>
this means that the sql that produced this result set can be something like:
"SELECT date AS " + Constants.START_DATE + " FROM some_table";
Hence, the jspc compiler will pick up any mistakes in names.
2) Along a similar thought, why use
StatementTag _stmtTag =
(StatementTag) findAncestorWithClass(this,
Class.forName("org.apache.taglibs.dbtags.statement.StatementTag"));
when a compiler could catch errors early with the equivalent:
findAncestorWithClass(this, StatementTag.class);
Any thoughts?
Regards,
Nick
