Data access failure

[techbrainless]

Hi All,

I just have started learning spring roo , i have checked the examples (timer,vote,...) and i have successed to run them ..

I have also made my own simple example and it worked fine......

now I am facing the following application , here is the roo script

project --topLevelPackage com.springsource.category.types

persistence setup --provider HIBERNATE --database HYPERSONIC_PERSISTENT

entity --class ~.Category --testAutomatically
field string categoryName --notNull 
field string description 
field reference --fieldName categoryParent --type ~.Category 

controller all --package ~.web

logging setup --level DEBUG --package WEB
logging setup --level DEBUG

perform package
perform eclipse

the idea of the above is that the category may contains 0,1,2,...,n subcategories , and each subcategory contains 0,1,2,...n subsubcategories , and etc... ( all categories,subcategories,subsubcategories..... should be stored in the same table)


but when i run the war file it display some error ( when i clicke "list of categories")

Data access failure

Sorry, a problem occurred while accessing the database.

Details

I remember hitting this issue with an earlier roo relase, it didn't like recursive entities, what version of ROO are you using?

[techbrainless]

Thanks alot for the reply ,

I am using the version 1.0.2.RELEASE [rev 638].

[whyBish]

Try 1.1, if it doesn't work log an issue providing your roo script. When I looked yesterday I couldn't find any issues for this.

[techbrainless]

Thanks alot for your reply ,

I have used 1.1 but still am getting the same error .

here is the roo script :

project --topLevelPackage com.springsource.category.types

persistence setup --provider HIBERNATE --database HYPERSONIC_PERSISTENT

entity --class ~.Category --testAutomatically
field string categoryName --notNull 
field string description 
field reference --fieldName categoryParent --type ~.Category 

controller all --package ~.web

logging setup --level DEBUG --package WEB
logging setup --level DEBUG

perform package
perform eclipse

and the error is :

[whyBish]

in your hibernate.cfg.xml, is autoddl set to 'create'?
