[Persistence, JBoss/CMP, Hibernate, Database] - JBoss 4.2.2.GA + Hibernate + tutorial application from Getti
by zlosynus
Hi,
I am new user to JBoss and Hibernate. I wanted to test deploy sample application. I have downloaded http://docs.jboss.org/jbossas/getting_started/v5/pdf/startguide.pdf and started go step by step throught chapter 9. I downloaded source codes http://docs.jboss.org/jbossas/getting_started/v3/startguide40.zip.
Because I am using MySQL in JBoss, I made some reconfigurations in hibernate example, first hibernate-service.xml:
| <server>
| <mbean code="org.jboss.hibernate.jmx.Hibernate"
| name="jboss.har:service=Hibernate">
| <attribute name="DatasourceName">java:/DefaultDS</attribute>
| <attribute name="Dialect">org.hibernate.dialect.MySQLDialect</attribute>
| <attribute name="SessionFactoryName">java:/hibernate/SessionFactory</attribute>
| <attribute name="CacheProviderClass">org.hibernate.cache.HashtableCacheProvider</attribute>
| <!-- <attribute name="Hbm2ddlAuto">create-drop</attribute> -->
| </mbean>
| </server>
|
Here is my mysql_ds.xml:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <!-- $Id: mysql-ds.xml 63175 2007-05-21 16:26:06Z rrajesh $ -->
| <!-- Datasource config for MySQL using 3.0.9 available from:
| http://www.mysql.com/downloads/api-jdbc-stable.html
| -->
|
| <datasources>
| <local-tx-datasource>
| <jndi-name>DefaultDS</jndi-name>
| <connection-url>jdbc:mysql://localhost:3306/cezAS</connection-url>
| <driver-class>com.mysql.jdbc.Driver</driver-class>
| <user-name>username</user-name>
| <password>password</password>
| <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
| <!-- should only be used on drivers after 3.22.1 with "ping" support
| <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>
| -->
| <!-- sql to call when connection is created
| <new-connection-sql>some arbitrary sql</new-connection-sql>
| -->
| <!-- sql to call on an existing pooled connection when it is obtained from pool - MySQLValidConnectionChecker is preferred for newer drivers
| <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
| -->
|
| <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml -->
| <metadata>
| <type-mapping>mySQL</type-mapping>
| </metadata>
| </local-tx-datasource>
| </datasources>
|
Then I tried to deploy example:
ant -f jboss-build.xml
and everything went fine:

[Installation, Configuration & DEPLOYMENT] - JBoss 4.0.4: Classloader not found exception when deploying
by engela
(JBoss 4.0.4, JDK 1.5)
I have two web applications, which are using the same jar file and are to be deployed on the same JBoss AS instance. In both cases the jar file will be included in the WEB-INF/lib, as potentially they will be using different version of the jar file. Both appplications are running fine when deployed on two different machines. However I have problems when deploying both WAR files on the same JBoss AS instance: For one particular command I get a Exception:
1:05:54,114 ERROR [[schedulerServiceExporter]] Servlet.service() for servlet schedulerServiceExporter threw exception

After reading:
http://wiki.jboss.org/wiki/ClassLoadingConfiguration
http://java2.5341.com/msg/68202.html
I tried several scenarios to solve my problem but neither of these have worked:
1. Set the attribute Java2ClassLoadingCompliance in JBOSS_HOME\server\default\deploy\jbossweb-tomcat55.sar\conf\jboss-server.xml to a) true and b) false
2. Add the line to the jboss-web.xml of the first war file:
<loader-repository>com.dns:loader=my-webapp1.war</loader-repository>
and add the line tothe jboss-web.xml of the second war file
<loader-repository>com.dns:loader=my-webapp2.war</loader-repository>
3. Add the lines to both jboss-web.xml:
<loader-repository-config>java2ParentDelegation=false</loader-repository-config>
|
I am running out of ideas. Did anyone have similar problems and found a work around?
Thanks,
Anette

[JBoss Cache: Core Edition] - Re: Best use of Jboss Cache Implementation
by manik.surtani＠jboss.com
Yeah, there is no similar concept of "groups".
Fqn is basically a path in a tree structure. JBoss Cache uses a tree as a data structure, and stores key/value pairs in nodes in the tree.
Simplistically, if you did not care about any optimisations around the tree structure, you could just create Fqns based on the yupe of data you are storing, sort of like namespaces. E.g.,
| cache.put("/org/mycompany/customerdata", "customer1", c1);
|
Now since all locking and replication happens on a per-node basis, you may optimise further to do something like:
| cache.put("/org/mycompany/customerdata/customer1", "customer1", c1);
|
so that each node contains information pertaining to a single entity.
Regarding singletons, it is a valid pattern, only we don't implement it internally and prefer users to do this themselves based on their environment e.g., an IoC framework may have it's own mechanism of creating, maintaining and injecting singletons, a Java EE environment may use JNDI, or simplest of all, you may create a CacheSingleton class with a single static getInstance() method.
HTH,
Manik
