Carlos,
Estou usando OJB em conjunto com portlets.
Tudo tava funcionando bem em meus testes com o pluto + OJB + mysql.
Ai quando coloquei no portal definitivo liferay + OJB + mysql não funcionou
mais!
To achando que é alguma incompatibilidade do liferay com mysql se bem que
nao deveria dar problema... É muito estranho, pq quando a base é oracle
funciona.
Bem, muito obrigado pela sua ajuda, grande abraco,
marcel.

Subject: Re: Error in beginTransaction!
I don't know if this affects you, but I have serious trouble with
maxIdle 2... So I always set it to 2 or greather...
Since you configured to use TestOnBorrow, check query you are using to
make this test. I use something like select 1 from DUAL in Oracle
databases, and select 1 in MS SQL. I don't know what you can do in
MySQL, but choose one very fast, because it could has heavy impact on
your app later...

Olá!
Marcel, eu trabalho com o OJB a uns 4 anos... e não tenho problemas com
beginTransaction. Porém, com o SapDB, notadamente, eu tinha problemas
para obter conexões se eu deixasse o parametro maxIdle = 1 ou maxIdle =
0... E o SapDB também tinha o péssimo hábito de fechar minhas conexões e
não re-abrí-las. Então, eu sempre usei maxIdle = 2, e TestOnBorrow=true
e ainda a query que eu usava para o teste (que não ví na tua
configuração) era select 1 from DUAL, e no MS SQL é simplesmente
select 1.
Eu até tinha esquecido deste parametro (maxIdle), e não mudei quando
migrei de SapDB para Oracle e posteriormente para MS SQL...
Espero que isto ajude.
