DODS4.x doml is completely different from DODS5.1 doml, but,
   DODS3.x is similar and you can use tool:
   doml31_2_doml50 - tool for converting doml3.x to doml5.x.
   This tool is in <dods5.1_root>/bin directory.
   Syntax of doml5.1 is defined in <dods5.1_root>/build/dtd/doml.dtd file

   The attribute "isConstant" (you wrote "isConstand" but we assume that you
meant "isConstant") exists in tag <column>, but,
   the attribute "isUnique" doesn't exist any more. You can define unique
index using new index syntax.

Origin (base) version of DODS 5.1 is DODS 3.5 (not DODS4.x), this is the
reason of package problem.

The dods-runtime.jar is used for runtime and the dods.jar is used for
generating code, sql, ...
Next days you can find new versions of that files (on CVS and binary
versions) where classes are changed and updated.
You can use dods.bat (dods in Linux) Wizard for creating sql, java code and
documentation.

Don't use types.conf file; it will be ejected. You can customize
dodsConf.xml (field LONGVARBINARY for MySQL).





3. ANT

Setclass and setbuildclass set all neccessery jar files which used during
development of application into classpath. You can't replace them with
ant.jar and antcontrib.jar.
