Hi everybody,
i'm working to adapt Jforum my needed and i have implemented in Jforum other stats and in particular one function that permit to complete delete a user and all about him like posts, topics privmsgs and so on.
I see that the deletion work fine, but i have a problem that is much probable is caused by the cache.
When i delete definitively the User, after i go take a look in the forum and i see that every topic in which there was a post wrote by the user deleted, is not shown. Only when i re-deploy Jforum i see correctly the topic and the posts.
What you think about?
...there is a method to force the cache re-init?
...i have tried to disable the cache in jforum-custom.conf but not solve nothing

Thank a lot for your help

Afaik, the only way to rebuild the topics listing cache is to restart the jForum webapp (which re-deploying does). Most Application server have tools that allow you to restart just a specific webapp and not any others. E.g., Tomcat's manager application (/manager/html) allows you to do this.

Thank you a lot for the reply,
i have solved in another way i don't now if is much clean but work much well!"
So i have used the same method that is used in Jforum to delete and update statistics, and i have taken from there what i need, in particular i have create this method:



public void postDeletion(int postId, int forumId, int userId) {

UserDAO um = DataAccessDriver.getInstance().newUserDAO();
User u = um.selectById(userId);
// Post
PostDAO pm = DataAccessDriver.getInstance().newPostDAO();
Post p = pm.selectById(postId);

if (p.getId() == 0) {
return;
}

TopicDAO tm = DataAccessDriver.getInstance().newTopicDAO();
Topic t = TopicRepository.getTopic(new Topic(p.getTopicId()));

if (t == null) {
t = tm.selectRaw(p.getTopicId());
}

if (!TopicsCommon.isTopicAccessible(t.getForumId())) {
return;
}

pm.delete(p);
DataAccessDriver.getInstance().newUserDAO().decrementPosts(p.getUserId());

// Karma
KarmaDAO karmaDao = DataAccessDriver.getInstance().newKarmaDAO();
karmaDao.updateUserKarma(p.getUserId());

// It was the last remaining post in the topic?
int totalPosts = tm.getTotalPosts(p.getTopicId());

if (totalPosts > 0) {
// Topic
tm.decrementTotalReplies(p.getTopicId());

int maxPostId = tm.getMaxPostId(p.getTopicId());
if (maxPostId > -1) {
tm.setLastPostId(p.getTopicId(), maxPostId);
}

int minPostId = tm.getMinPostId(p.getTopicId());
if (minPostId > -1) {
tm.setFirstPostId(p.getTopicId(), minPostId);
}

// Forum
ForumDAO fm = DataAccessDriver.getInstance().newForumDAO();

maxPostId = fm.getMaxPostId(p.getForumId());
if (maxPostId > -1) {
fm.setLastPost(p.getForumId(), maxPostId);
}
}

PostRepository.remove(t.getId(), p.getId());
TopicRepository.loadMostRecentTopics();
ForumRepository.reloadForum(p.getForumId());

TopicRepository.clearCache(p.getForumId());
PostRepository.clearCache(t.getId());
ForumRepository.updateForumStats(t,u,p);
}

Thank you a lot, if can be useful i can post all the Complete deletion method,
best regards Federico
