iPOJO: Constructor Injection using XML metadata
Hi,
I have a question concerning iPOJO and constructor injection. In the
documentation I see that constructor injection was introduced with the
1.7.0-SNAPSHOT of iPOJO and that you are able to mark constructor
parameters using the @Requires annotation. However absent from
documentation is how to perform constructor injection using XML
metadata. I'm currently using version 1.8.0 of iPOJO and I can't seem
to find any attributes in the Requires element schema that would make
sense for constructor injection. I was wondering if 1.8.0 support
constructor injection via XML metadata? If so, could you provide a
simple example? If not, is adding the ability to specify constructor
injection in XML metadata going to be in a future release?
Regards,
Andrew
Why the OSGI Configuration is bound to a config admin bundle, and not visible to other app bundles?
Posted by ext2 <xu...@tongtech.com>.
Hi:
I have a bundle which will deploy a properties file as OSGI
Configuration, temporary I just call this bundle as a "config admin
bundle";
Most time, after "config admin bundle" update configuration , the
application bundle can got it immediately. But rarely, the application
bundle must wait for 4~~5 second, otherwise the application bundle can only
get a OSGI Configuration which properties is null(
Configuration.getProperties() return NULL).
And also a error in log shows: the configuration has been bound to
the "config admin bundle";
Why the application must wait for 4~5 seconds? I have confirmed that
I have reset the configuration's bundle location to NULL in the "config
admin bundle";

Hi,
It's already supported, just not documented yet:
Add 'constructor-parameter="constructor parameter index (0 based)"' in your <requires> or <property> such as in:
<requires constructor-parameter="0"/>
<properties>
<property constructor-parameter="1" value="Hello"/>
</properties>
for a class containing:
public Foo(LogService log, String message) {
...
}
Regards,
Clement
