How to create persistent MUC?

Hi,

I’m trying to create persistent MUC room (stored in database).

MultiUserChat muChat = new MultiUserChat(conn, roomJid);

muChat.create(nickName);

Form form = new Form(Form.TYPE_SUBMIT);

form.setAnswer(“muc#roomconfig_persistentroom”, true);

muChat.sendConfigurationForm(form);

muChat.changeSubject(subject);

With that I’ve got an exception:

java.lang.IllegalArgumentException: Field not found for the specified variable name.

at org.jivesoftware.smackx.Form.setAnswer(Form.java:253)

What am I doing wrong?

You need to use the correct answer form which can be obtained by

// Get the the room’s configuration form

Form form = muc.getConfigurationForm();

// Create a new form to submit based on the original form

Form submitForm = form.createAnswerForm();

before using setAnswer()

To use setAnswer() you have to actually get the form, not create it yourself.

Check the documentation on form usage.
