问题 So, basically I want a Batch file to read a .txt. The problem is that the Batch file needs to update everytime a new line gets written to the .txt @echo off set "pc=%1" FOR /F "delims=:" %%A IN ('findstr /N .* "%pc%"') DO set "zeilen=%%A" type %pc% set /A zeilen1=%zeilen% :loop if not %zeilen% == %zeilen1% ( set "line=" set zeilen2=%zeilen% - 1 for /f %%a in ('more/e +%zeilen2% ^< %pc%') do ( if not defined line set "line=%%a" ) echo %line% set /A zeilen+=1 ) FOR /F "delims=:" %%A IN (

问题 I wonder if there is a way to query the XMPP server (passing user JID?) to find out what chat room(s) this user is currently in? If not, can we query jabber server to get a list of all active chat rooms? BTW we're running ejabber enabled for multiuser chat. A solution using a java library (smack?) would be ideal. 回答1: As mentioned by Joe Hildebrand, there is no such a standard feature as it is a privacy violation to allow that over XMPP, so you cannot expect to do that from Smack. Maybe with

问题 In xmpp, following 2 users could join multi-user chat(MUC) or subscribe to same pub-sub node? public@service.com/user1 public@service.com/user2 回答1: When joining an anonymous MUC room, a room where others do not know the "real" JID of others in the room, the connecting user provides their own JID. When joining a non-anonymous room the users provide their full JID which is transmitted then to all occupants. In either case there is nothing to prevent the user from joining with the same bare JID

问题 I'm working on a chat application which I would love to use a SQL db for. My problem is, after a few google searches, i have people telling me from one site, that using a DB would be much slower then using a normal file (e.g Text or JSON file), but then on some other sites, people are saying the complete opposite. And I don't know about you guys, but when it comes to creating web apps for users, the users always come first. So as much as I'd love to use a SQL DB as 1.) I have good experience

问题 I need to implement long polling or pending request for a chatroom. I tried a4j:push, but it seems doesn't work like a real long polling approach (see the following discussion: https://community.jboss.org/message/16614). The question is: which alternatives do I have to realize long polling? I'm using JSF 1.2, JAVA EE 6 and RichFaces 3.3.2. Thaks in advance! 回答1: You need to use the a4j:poll component from RichFaces. The exadel live demo has a very nice sample and explains the main properties.
