Intercepting messages

If I need to process/modify a message at the server before sending it out to the receiver, where is a good place to do it? Should it be in SessionImpl::deliver ()?

Thanks in Advance.

Can you provide some more details about what you’'re trying to do? Do you need to modify all messages in the system, implement a service, etc?

Regards,

Matt

Hi Matt,

I want to process all messages, make text substitutions in them or rewrite them before sending them to the client. Messages in a session as well as offline msgs.

Thanks.

Hi Matt,

Looks like the place to put a hook is in MessageRouterImpl::route(). Is this right?

Another thing: I get an error at startup:

+java.lang.NullPointerException

at org.jivesoftware.messenger.muc.HistoryStrategy$Type.valueOf(HistoryStrategy.jav a:1)

at org.jivesoftware.messenger.muc.HistoryStrategy.setTypeFromString(HistoryStrateg y.java:221)

at org.jivesoftware.messenger.muc.HistoryStrategy.setContext(HistoryStrategy.java: 241)

at org.jivesoftware.messenger.muc.spi.MultiUserChatServerImpl.initialize(MultiUser ChatServerImpl.java:483)+

Seems like it is trying to do

historyStrategy.setContext(“xmpp.muc.history”);

in MultiUserChatServerImpl::initialize, and xmpp.muc.history.type is not defined.

Thanks for the bug report. The problem was fixed and the solution will be available in the next nightly build.

Thanks,

you should “insert into jiveproperty( name, propValue) valus(’‘xmpp.muc.history.type’’,’‘number’’)” to solve your problem.

I need to modify or reject any message passed throuch server.
