Hi,

I have mapped a varchar (in mysql) to a String, and set the length=** value in the mapping.

<property
name="Comment"
column="COMMENT"
type="string"
not-null="false"
length="200"
/>

I would like to check at runtime if the length of the String is not bigger then the length stated in the mapping. I looked into ClassMetaData and StringType, but could not find any references to the maximum length of a StringType. Is there any way to look this up?

Thanks a lot,
Leen Toelen

Code:

       Iterator columns = Configuration.getClassMapping("your persistent class").getTable().getColumnIterator();
       for(;columns.hasNext();)
       {
              Column thisColumn = (Column) columns.next();
              if ("COMMENT".equals(thisColumn.getName()))
              {
                    length =  thisColumn.getLength();
              }
       }

Great, I just have to save the Configuration for my session right now, but this method works like a charm.

Thanks a lot!
