Thanks for the answers.
After you told me how to solve my problem, I found an old article of you
describing how to use the configuration admin service with cfg files :
http://ipojo-dark-side.blogspot.fr/2009/04/ipojo-and-file-install-configuring.html
So I installed config-admin and file-install bundles (felix bundles) but it did
not work at first. In fact, I had to rename my component from tcp-handler to
tcphandler (with no - in the name) and create the cfg file as you said.
Now everything work :-)

Hi,
Yes, changing the metadata.xml file won’t work as it is not read at runtime.
What you can do is to externalized the instance declaration in a ‘cfg’ file (if
your runtime support this format). cfg files are generally use to push
configurations to the configuration admin.
In your case it would be something like : tcp-handler-instance.cfg, with the
following content:
serverIP=……
serverPort=8080
Changing the cfg file reconfigure the instance.

Clement

I believe the metadata.xml file is not actually used after you compile... have
a look at the jar's manifest instead, IPojo saves all the information it needs
in the manifest after compilation, so if you change it there it should work.
However, it seems to me you need to find a better way to configure this kind of
thing... Maybe others can help here?

Subject: [iPOJO] Modifying a metadata.xml property directly in the JAR
Hello,
I just created a TCP client to communicate with a server using iPOJO.
For now, I used the property fields into the component "instance" to
configure the IP address of my server. Something like that :
<instance component="tcp-handler">
<property name="serverIp" value="xxx.xxx.xxx.xxx"/>
<property name="serverPort" value="yyyy"/>
</instance>
My purpose is to easily modify this configuration when I move my server
on another device without asking the user to set the IP address
everytime the client is started. And i'd like not to use a config file
because I assume that the metadata.xml is already some kind of a config
file.
So, I though that using "instance" enables me to modify the metadata.xml
file into the JAR file and update this JAR with the new value. In fact,
Ubuntu asks if I want to update the archive after modifying a file and I
say yes. I can see the change when I reopen the archive.
However, it seems that when my client is launched in Felix, it always
uses the old IP address despite changes I made in the JAR file.
What's wrong with my way of configuring my component ? Is it possible to
modify a file into a JAR file ? Is the value of my property is
definitively set into the component "instance" in the metadata.xml (like
a static field) ?
Thanks,
Regards.
