XWiki Silicon Valley Meetup this week - Oct 16 to Oct 21st ?

by Ludovic Dubost

With Jeremi, we are visiting Silicon Valley thanks to Google organizing a Summer of Code Mentor Meetup. We will be staying one week until December 22nd. Maybe it could be possible to organize an XWiki Meetup sometime this week if somebody can host us. We could talk about what's currently happening on XWiki, XWiki's future, how XWiki is currently used and what we could improve. It could include any type of users XWiki. It could last a few hours after work time one evening. We will be staying a little out of town (Santa Cruz) but we have a car and can move to the valley in the evenings. We will also be back on Friday evening somewhere around Mountain View. The Meetup could also be saturday morning. Anybody interested and/or able to host the meetup ?

In linux, there is no difference to windows. There could be a problem if you have a web server running on the same machine.

RE: [xwiki-users] delete spam comments

Re: [xwiki-users] delete spam comments

by wangwh＠att.net

If your Wiki is getting some traffic, you can be the next target also, someone can put in lots of spam comments with nothing but links to his/her sites to promote the sites. If possible, you might want to allow only certain people to leave comments. *** I assume people reading this email do not do this, but... To some *ill-minded* Wiki users, please stop doing that to others! (the sites you are advertising will get bad names...) -------------- Original message ---------------------- From: wangwh(a)att.net > Hi, > My wiki site got over a thousand spam comments, anyone know how can I delete > them quickly (better than edit object, then delete one by one). > Wei-hsing >

Java Stack Tracing Saving 7MB Attachment

by Smith, Nathan

Dear xwiki-users, We are getting a Java exception when saving a 7MB attachment. The attachment appears to be attached properly, since it appears in the attachment list and can be downloaded after the error. However, after attaching four or five files the server becomes so unresponsive that a restart is required. Configuration Info: OS: Windows 2000 Server RAM: 1GB JDK: 1.5.0_8 App Server: JBoss 4.0.4 Database: MySQL 4.1.21 Note that JBoss is run with -Xmx 512M, and increasing that to -Xmx 1024M has no effect. I've gone through the attachment documentation and mailing list archives and didn't see any references to a similar problem. Any help would be appreciated - I plan to checkout the code and see what's happening! Here is the stack trace: A problem occured while trying to service your request.
