General Board / Re: Does multiple projects mean multiple databases
« on: February 29, 2008, 09:21:19 am »
Hi David,

but isn't it true that you can reuse elements from various models?

I can't double check atm, but I thought I'm using exactly this approach in some projects.

1) What is in your model? Structure model(s) or behavioural model(s)?

2) The link to your file needs a password...

Sorry wasn't aware of that - always loged on :).

The diagrams are normally class diagrams, nothing complicated.

General Board / Incompatible XMI files?
« on: February 10, 2006, 07:12:24 am »

we started using the XMI files (based on UML 1.3/ XMI 1.1) to exchange models between EA and other tools such as Umbrella.

The way from EA to the other tools is working fine.

But now I'm getting back a XMI file created by (in the special case Umbrella) and all that I do import is an empty folder. The importer says everything is fine.

Does someone knows what kind of problems this could be?

Header of the XMI file:

<?xml version="1.0" encoding="UTF-8"?>
<XMI xmlns:UML="org.omg/standards/UML" verified="false" timestamp="" xmi.version="1.2" >



PS: if you like to see the whole file that's not able to be imported:

I installed vanilla 4.1.14 and had no problems. Maybe .15 behaves a bit beta?

No I think the problem here is the UTF-8 integration. This is a new feature with some other stuff for the 4.1.15 and I know from other projects that UTF-8 is causing much bigger table columns and indexes :(

Hey Thomas,

actually yes that's what I'm saying.

On which MySQL Version and charset did you installed it?

I just downloaded all files new from the site and also created a new DB. For me everything is running at MySQL 4.1.15 with UTF-8 support and InnoDB enabled.

Tried both, InnoDB and MyISAM tables - both are reporting similar errors.


Are you trying to say, that MySQL throws that error when you create the database with the scripts from Sparx download area? If so there seems to be something wrong with your MySQL environment. Just a few weeks ago I installed a repository with the (then) recent release.

I just tried again to install a MySQL repository for my project. Actual MySQL 4.1.15 including UTF-8 support.

Now I get the error

CREATE TABLE t_objectproblems(
Object_ID int( 11 ) NOT NULL default '0',
Problem varchar( 255 ) NOT NULL ,
ProblemType varchar( 200 ) NOT NULL ,
DateReported date,
`Status` varchar( 50 ) ,
ProblemNotes text,
ReportedBy varchar( 255 ) ,
ResolvedBy varchar( 255 ) ,
DateResolved date,
`Version` varchar( 50 ) ,
ResolverNotes text,
Priority varchar( 100 ) ,
Severity varchar( 50 ) ,
PRIMARY KEY ( Object_ID, ProblemType, Problem ) ,
INDEX ObjectID( Object_ID ) ,
INDEX ObjectRequiresRequirement( Problem )
) TYPE = InnoDB COMMENT = "InnoDB free: 87040 kB"

MySQL error:
#1071 - Specified key was too long; max key length is 1024 bytes

Basically I do understand what this means, but is there any other solution than removing ProblemType, Problem from the PK?


PS: I'm wondering how you created these tables in first place - may be there is a configuration option that I can't find.

General Board / Shareing RTF Templates
« on: December 21, 2004, 05:14:10 am »
Hey all,

I'm still trying to read all the manuals and provided documentation for EA but it's soooo much - excellent work the Spar team did  ;).

So one thing I didn't found out yet is:
Is there a way to share RTF template resources within different projects?

I found out that I can create and modify them but I can't import/export them like I do it with the patterns or profiles.

Thx for help


General Board / Re: ERD class 2 OO class conversion
« on: December 14, 2004, 01:37:59 am »
There are two ways.
A) Export the tables package to XMI; edit the stereotypes; re-import it to the objects package.
B) write an addin working e.g. similar to ROSE's database modeller. There's quite a market for that and you could sell it  :)


Hey Thomas,

selling, please no more additional development. I'm member of the core development team of Mambo and have my own company doing consulting in the OO & IT strategy area, that's more then enough work to do.

But you got the point, I also would pay for such a plugin.

Thank's for the idea with the export, I'm going to test this.

ERDs will contain index columns and all kinds of other DB specific things. Also associations are not forward generated into the DDL, so for each relation you still need the corresponding attribute/column in the respective class.

In short: ERDs are too specific (my understanding).

Hey Mike,

basically this is no big deal. Java with J2EE is doing all the time. The Java beans are just a representation of an object and in the J2EE environment you just map it to a db table.

When I use a class template I'm already pretty close to what I want, because when you look at a persistent data holding class their attributes are normally what the table columns are. And for a complete storage you also need the additional internal index and PK fields. That these fields might not be public accessable can be changed in a second step.

First step would be, to create a object based on a table class. IMO it wouldn't be a big deal with all the technique I see that it is already implemented in EA.


General Board / ERD class 2 OO class conversion
« on: December 13, 2004, 09:36:37 am »
Hello everybody,

I was wondering if there is a possibility to automatically generate a OO class based on the ER table definition (which is stored in a class symbol).

The idea is the following. After I generated my whole DB I would like to automatically generate the objects for the database abstraction layer. For that I would need a class which has the same attributes as the ER table and get/set methods to access these attributes.

Is there a way to generate these classes, I had a look at EA but couldn't find it directly.



Bugs and Issues / Frame around included UML diagrams
« on: February 11, 2009, 09:35:47 pm »

Including a second UML diagram by using the feature "drop diagram as: diagram frame" is a great concept.

I have the issue that all of these frames however do not keep their proportions (size) after I change the default size (to smaller). I verified that the included diagram is the size I want and as long as I keep the diagram open all is fine. After closing and reopening again the diagram frame is changed again :-(.



Bugs and Issues / Re: EA & MS SQL very slow

Hi Folks,

With the European support of EA we finally found the solution.

1. Upgrade Vista to SP1 - seems like some general issues are affected
2. If performance will not increase

from 3 to 1

For me it works now :)

just so everyone in this thread knows..

When you say MS SQL, do you mean MySQL or SQL Server?

Microsoft SQL Server

I wrote a support ticket - no answer yet, but I'm sure it will come soon.

I'll keep you posted.
