Martin,
After not being able to generate the mapping and constantly getting the error mentioned earlier, I decided to switch to use a joined
strategy.
Well, I can now successfully save a model instance to the database.
That being said, I am just facing more issues.
First, off if you look at the ecore that I submitted, some columns are of type EEnums. When looking at the database, those enums are
not mapped as table. Looking at previous post, and at bug 182825 and at the default for enumerated columns being ordinal (9.1.21)
then how do I get the extra tables generated and the ordinal values saved instead of the text value in a standard varchar column.
2nd, I am trying to find the best and most efficient way to "initialize" the HbDataStore.
I have tried to set the USE_MAPPING_FILE property, only to get exception "org.hibernate.hql.ast.QuerySyntaxException: StTreeRoot is
not mapped, etc. I found a post of March 27 covering this issue, but here is what I get in my log:
DEBUG [30 Jul 2007 19:43] HbSessionDataStore.java: 156 : Searching hbm files in class paths of epackages
DEBUG [30 Jul 2007 19:43] StoreUtil.java: 514 : >>>> Building or descriptor file List
DEBUG [30 Jul 2007 19:43] StoreUtil.java: 528 : Try path: ;hibernate.hbm.xml
and then it moves on. I have tried to put the hibernate.hbm.xml file in the classpath (beside log4j.properties), at the root, in the
package directory. When comparing with the above mentioned post, I don't see any other try path listed or !found anywhere. Any clue?
Next, I have set the UPDATE_SCHEMA to false, to try to speed up the initialization (once the schema is stable, I believe that should
be the standard way to go). Anyway, I now get the following after executing a query:

this does not occur if the option is not specified. Any idea why this is happening?
At last, what would be your most efficient "initialization" routine for HbDataStore. Do you need to set EPackage every time? etc.
Thanks again for all your help. We're slowly but surely getting there.

Alain,
Which bug do you mean (182825 seemed to point to another bug)?
Not finding the hbm file can be caused by this issue:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=196535
This was solved in the build of 18 july. Which build are you using?
The other exception you get is this:
> Caused by: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException:
> Unknown column 'strootnode2_.concreteid' in 'field list'
Normally this occurs because the db schema is not in sync with the (in-memory) mapping. Does this
maybe apply to your case?
Other than this I have no real idea why this exception occurs when update_schema is false.
Yes the epackages are required for the initialization. The hbdatastore does some computation which
is not required for all users (adds econtainer mapping and computes referer relations). But overall
I don't think that this takes much time (I have never done performance measurements on that though).
Setting the update_schema to false surely saves time and it is the only option I know for getting
better start up times.

Martin,
I was using the version from July 12. After upgrading the version from the 21st, now both of my issue with the options have melted
away. Great news.
Now on the remaining point from my previous post:
If you look at the ecore that I submitted, some columns are of type EEnums. When looking at the database, those enums are not
mapped as table. Looking at previous post, and at bug 182825 and at the default for enumerated columns being ordinal (9.1.21) then
how do I get the extra tables generated and the ordinal values saved instead of the text value in a standard varchar column.
Thanks,
Alain

Hi Alain,
Yes it is true that the current default is String and not Ordinal. Overall in my view String is
better (at least it was for me). You can change this behavior by setting an @Enumerated annotation
in the edatatype of the enum.
A global option can also be of use here, please enter a bugzilla if you find that better.
I am not sure why you want to have the enumerated efeature stored in a separate table. Is it a list
of enumerates?

Martin,
After not being able to generate the mapping and constantly getting the error mentioned earlier, I decided to switch to use a joined
strategy.
Well, I can now successfully save a model instance to the database.
That being said, I am just facing more issues.
First, off if you look at the ecore that I submitted, some columns are of type EEnums. When looking at the database, those enums are
not mapped as table. Looking at previous post, and at bug 182825 and at the default for enumerated columns being ordinal (9.1.21)
then how do I get the extra tables generated and the ordinal values saved instead of the text value in a standard varchar column.
2nd, I am trying to find the best and most efficient way to "initialize" the HbDataStore.
I have tried to set the USE_MAPPING_FILE property, only to get exception "org.hibernate.hql.ast.QuerySyntaxException: StTreeRoot is
not mapped, etc. I found a post of March 27 covering this issue, but here is what I get in my log:
DEBUG [30 Jul 2007 19:43] HbSessionDataStore.java: 156 : Searching hbm files in class paths of epackages
DEBUG [30 Jul 2007 19:43] StoreUtil.java: 514 : >>>> Building or descriptor file List
DEBUG [30 Jul 2007 19:43] StoreUtil.java: 528 : Try path: ;hibernate.hbm.xml
and then it moves on. I have tried to put the hibernate.hbm.xml file in the classpath (beside log4j.properties), at the root, in the
package directory. When comparing with the above mentioned post, I don't see any other try path listed or !found anywhere. Any clue?
Next, I have set the UPDATE_SCHEMA to false, to try to speed up the initialization (once the schema is stable, I believe that should
be the standard way to go). Anyway, I now get the following after executing a query:

this does not occur if the option is not specified. Any idea why this is happening?
At last, what would be your most efficient "initialization" routine for HbDataStore. Do you need to set EPackage every time? etc.
Thanks again for all your help. We're slowly but surely getting there.

Alain,
Which bug do you mean (182825 seemed to point to another bug)?
Not finding the hbm file can be caused by this issue:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=196535
This was solved in the build of 18 july. Which build are you using?
The other exception you get is this:
> Caused by: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException:
> Unknown column 'strootnode2_.concreteid' in 'field list'
Normally this occurs because the db schema is not in sync with the (in-memory) mapping. Does this
maybe apply to your case?
Other than this I have no real idea why this exception occurs when update_schema is false.
Yes the epackages are required for the initialization. The hbdatastore does some computation which
is not required for all users (adds econtainer mapping and computes referer relations). But overall
I don't think that this takes much time (I have never done performance measurements on that though).
Setting the update_schema to false surely saves time and it is the only option I know for getting
better start up times.

Martin,
I was using the version from July 12. After upgrading the version from the 21st, now both of my issue with the options have melted
away. Great news.
Now on the remaining point from my previous post:
If you look at the ecore that I submitted, some columns are of type EEnums. When looking at the database, those enums are not
mapped as table. Looking at previous post, and at bug 182825 and at the default for enumerated columns being ordinal (9.1.21) then
how do I get the extra tables generated and the ordinal values saved instead of the text value in a standard varchar column.
Thanks,
Alain

Hi Alain,
Yes it is true that the current default is String and not Ordinal. Overall in my view String is
better (at least it was for me). You can change this behavior by setting an @Enumerated annotation
in the edatatype of the enum.
A global option can also be of use here, please enter a bugzilla if you find that better.
I am not sure why you want to have the enumerated efeature stored in a separate table. Is it a list
of enumerates?
