[JBoss Seam] - Seam namespaces.
by Phantom
Please help me! I don't have much time and resources for experiment and in documentation I didn't find the answer to my question...
In components.xml we can define XML namespaces in the header. Is it correct, that Jboss Seam looking for components only in this namespaces?
My problem is: I have several subprojects on my Jboss AS instance. In each subproject I have separate WAR and, for example, such Entity component as "user". Can I use namespaces for components division to separate projects? Now I should make some differences in names, for example: in first project user components called as "pr1user", in second "pr2user" and so on.
Thanks!

[Beginners Corner] - Context an Deployment of uncompiled apps (only dir)
by Schludi
Hello!
I am trying to deploy an old Tomcat application to JBoss and have some problems.
The first problem is, that i have no archives but an directory which needs to be copied. That leads to a hot deployment error - is the /deploy dir only accepting compiled archives?
The second problem is, that i have to set the context like it was in Tomcat. How can i do like this: (the file was in conf/catalina):
<?xml version='1.0' encoding='utf-8'?>
| <Context docBase="D:\dev\workspace\FAQ-DB-Backend\target\bbraun-faq-db-backend" path="/faqdb" workDir="work\Catalina\localhost\faqdb" reloadable="true">
| <Resource name="jdbc/FAQ_DB" type="javax.sql.DataSource"/>
| <ResourceParams name="jdbc/FAQ_DB">
| <parameter>
| <name>username</name>
| <value>user</value>
| </parameter>
| <parameter>
| <name>password</name>
| <value>pass</value>
| </parameter>
| <parameter>
| <name>url</name>
| <value>jdbc:microsoft:sqlserver://localhost:1433;SelectMethod=cursor</value>
| </parameter>
| <parameter>
| <name>driverClassName</name>
| <value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
| </parameter>
| <parameter>
| <name>maxWait</name>
| <value>5000</value>
| </parameter>
| <parameter>
| <name>maxActive</name>
| <value>4</value>
| </parameter>
| <parameter>
| <name>maxIdle</name>
| <value>2</value>
| </parameter>
| </ResourceParams>
| </Context>
