Problems migrating Enhydra 3.1 to 5.1

Hi!

I tried to migrate my application from 3.1 to 5.1,
but I failed. I was facing to many problems.
Maybe you can help me.

1. DODS
 - The appname.doml file seems to have a completely new syntax compared
   with DODS 4.0. So I rewrote it. 
   When I use the attributes "isConstand" or "isUnique" the generator
   gives an error message, that these attributes are not defined.
   Why?
 - In DODS 4.0 some classes were put from the package com.lutris.dods to
   org.enhydra.dods. In Enhydra 5.1 the classes are put back to
com.lutris.dods?
 - There are two jars for DODS: dods.jar and dods-runtime.jar
   What is dods.jar good for? It seems that dods-runtime consists of the
same classes
   plus some additionals.
 - And the problem where I stuck completely is the following:
   I use MySql as database. I tried to customize the types.conf file,
because
   we are using the types "blob" and "text".
   So I appended the type "Text" to Standard_JDBC.TYPE_NAMES[] and
inserted the following
   section:
   Standard_JDBC.Text.SQL_TYPE=TEXT
   Standard_JDBC.Text.JDBC_TYPE=Clob
   Standard_JDBC.Text.JAVA_TYPE=byte[]
   Standard_JDBC.Text.JAVA_TYPE_CLONE="<JAVA_VAR>.clone()"
        
   The column in my appname.doml file looks like this:
            <column  isPrimaryKey="false" id="text"  usedForQuery="true"
>
              <type canBeNull="true" dbType="TEXT" javaType="byte[]"/>
            </column>

   Now the generator throws an EjenException. What's wrong?

2. KELP with JBuilder 7
 - Kelp 5 is not working with toolbox 5.1 from Enhydra 5.1.
   So I changed the toolbox to version 5.0.
   Will there be a Kelp for Enhydra 5.1?
 - The Deployment Wizard freezes the whole Jbuilder when I
   click on the "archive" or "run" - tab.
   Does anybody else have this problem?
 - (BTW: I've to add the path to the log4j.jar lib manually to 
    jbuilder.conf, because Kelp needs the logger)

3. ANT
 - After compiling Enhydra 5.1 I found the following line in 
   enhydra5.1/bin/ant:
   CLASSPATH=$CLASSPATH:$(setclass):$(setbuildclass)

   What does setclass and setbuildclass mean?
   I guessed, that I've to replace it with
   "enhydra5.1/build/ant.jar" and "enhydra5.1/build/antcontrib.jar"
   Is this correct?
   Since I made the replacement my "configure" - scripts are running.

Many Questions here.
Maybe somebody can help.

Thanks in advance!
