RE: Dynamic configuration of datasource

[Siano, Stephan]

Hi,

The properties file part depends on the felix file installer as it is 
configured in karaf. You can use and configure the file installer on other OSGi 
servers the same way (I have done this on equinox) or you have to set your 
config admin properties by other means.

The blueprint property placeholder requires aries-blueprint-cm (and of course 
the config admin service), so it's not specific to karaf.

Best regards
Stephan

Hello Martin,

Is this a karaf solution ? because I can't use karaf for my example :(

Yould could do
<blueprint>
   <cm:property-placeholder id="p" persistent-id="my.persistent.id.jdbc.mysql">
        <cm:default-properties>
            <cm:property name="database" value="user" />
            <cm:property name="server" value="localhost" />
            <cm:property name="port" value="3306" />
            <cm:property name="user" value="root" />
            <cm:property name="password" value="root" />
        </cm:default-properties>
  </cm:property-placeholder>

  <bean id="dataSource" class="com.mysql.jdbc.jdbc2.optional.MysqlDataSource">
    <property name="url" value="jdbc:mysql://${server}:${port}/${database}/>
    <property name="user" value="${user}" />
    <property name="password" value="${password}" />
  </bean>
</blueprint>

The defaults can be overridden with a etc/my.persistent.id.jdbc.mysql.cfg 
properties file.

Hello everyone,

I developed an example that uses JPA to persist some data.
Right know, here is the configuration of my datasource

<blueprint>
  [...]
  <bean id="dataSource" class="com.mysql.jdbc.jdbc2.optional.MysqlDataSource">
    <property name="url" value="jdbc:mysql://localhost:3306/user />
    <property name="user" value="root" />
    <property name="password" value="root" />
  </bean>
  [...]
</blueprint>

I'd like to dynamically set the different values (with a configuration service 
maybe ?) and I don't know how to do it.
