Problem with DB2 Support in 5.4

[saatsch]

Hey all !

when running

ant db.create‍

I got the following Error:

     [java] org.activiti.engine.ActivitiException: couldn't deduct database type from database product name 'DB2/LINUXZ64'

I think you should add this database type to the databaseTypeMappings here: http://svn.codehaus.org/activiti/activiti/trunk/modules/activiti-engine/src/main/java/org/activiti/e...

Anyway, after some hacking, I got it to work.
But I think I have found a bug here:
http://svn.codehaus.org/activiti/activiti/trunk/modules/activiti-engine/src/main/resources/org/activ...

where it says:

create table ACT_ID_INFO (
    ID_ varchar(64),
    REV_ integer,
    USER_ID_ varchar(64),
    TYPE_ varchar(64),
    KEY_ varchar(255),
    VALUE_ varchar(255),
    PASSWORD_ BLOB,
    PARENT_ID_ varchar(255),
    primary key (ID_)
);‍‍‍‍‍‍‍‍‍‍‍

You should declare the column ID_ with NOT NULL, because DB2 cannot have a column in the primary key, where null values are allowed. See also http://www.google.com/search?q=SQL0542N

Greets, and keep up the good work !

Thanks for the pointer, will fix the NOT NULL on trunk and add the mapping!
