[JBoss jBPM] - Re: SQL error executing test process
by ajvarela
Thank you all for replies.
I dont know how I can prevent the recreation of DB schema. I have tried comment the tearDown mehod code and the test run well but
residual information is saved on DB when I reactive the tearDown code the error appear again.
This is my config for MySQL. Is correct dialect??
<property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>
| <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
| <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/jbpmdb</property>
| <property name="hibernate.connection.username">root</property>
| <property name="hibernate.connection.password">*********</property>
| <property name="hibernate.format_sql">true</property>

[JBoss jBPM] - JBPM4: FOREIGN KEY problem
by hexiaofeng
hi.
A question block me, Please help me .thank you very much.
I download jbpm-4.0.CR1. Import jbpm.mysql.create.sql contents to MySql 5.
I create Order and TestUpdate , When I run TestUpdate , some exception print in cnosole. It seems question is FOREIGN KEY problem.
Please tell me how to fix it. Thank you very much.
Below are source code, and exceptin message.
