    any one help with null  transaction reference problem?

    William Woodman Master

      spent some time on the seam forum and was pointed to ejb or hibernate forum instead.

      essentially I have a home laptop and and works laptop

      both running 4.2.2 AS server, and a copied a seam project from jboss tools 2.0 from the home pc (where it works) to the work pc where it doesnt .

      The works pc errors on null pointer in a transaction (im using seam framework pojo daos (therefore not strictky speaking ejb beans)

      my code/config is the same but cant resolve why i get this null error

      does any one have ideas what might be going one

      - herees the crumb trail from the seam thread


      having a problem on my laptop with basic seam2.01 project using jboss tools

      I have created a simple entity object and jboss tools in eclipse has created an entityHome and entityList framework objects

      when i run the basic app its okay until i try and create a Node Entity off the NodeHome

      i get an error sugeesting that their is no transaction and then get all sorts of errors on the nodeHome.persist method

      I run the code inside jboss 4.2.2, its currently a generated POJO not an ejb

      I think this is an issue with the seam transactio handling (without ejb).

      i have a line in persistence xml as - but cant find any seam.jsf.TransactionalSeamPhaseListener - as mentioned in the JBOSS SEAM book.

      any ideas what i've done wrong?

      non transactional calls seem to work okay for ordinary method forms (no db work)
