[Beginners Corner] - Caching large volumes of entities
by ihunter
Hi Folks,
We have a server designed to serve 'live' database data. We have now been asked to provide a facility for querying 'historical' database data from the database.
I *think* that serving up large volumes of historical data would consume resources and slow down the live service. [I *really* think the historical stuff should be on another box but thats another fight.....]
I propose to NOT use JBoss CMP, but to go straight to JDBC for these historical queries [the queries will also be paged for performance].
Does anybody have similar experiences they can share, and any alternative ideas. For instance, can I destroy the cache for the historical data when the data has been sent to the client - if so, an example would be really great.
Any ideas or comments appreciated
Ian Hunter

[Installation, Configuration & Deployment] - Problems facing Installation of JBoss
by raj.shanmug
Could you help further in going ahead with this installation. I have followed the following steps.
>From Binary
1. I have downloaded the jboss AS 4.0.2.zip and extracted the same in my E:/Server and renamed the same folder as E:/Server/jboss
2. Then I downloaded the jboss portal 2.4.zip and also extracted the same in E:/ seperately.
3. Then I set the environmental variables as follows;-
PATH: C:\Java\jdk1.5.0_08\lib; E:\Server\jboss\lib;
CLASSPATH: C:\Java\jdk1.5.0_08\bin; E:Server\jboss\bin;
JAVA_HOME: C:\Java\jdk1.5.0_08
JBOSS_HOME: E:\Server\jboss
4. Then I created a SQL Server Data base instance in another system and granted rights for me. The db details are host:pegsrv; username: peguser ; password: password.
5. Then I copied the jdbc driver files pertaining to Sql server i.e, msbase.jar, msutil.jar, mssqlserver.jar into the E:\server\jboss\default\lib directory of the AS.
6. Then I configure the portal-sqlsdrver-ds.xml file as follows
<?xml version="1.0" encoding="UTF-8"?>
<local-tx-datasource>
<jndi-name>PortalDS</jndi-name>
<connection-url>jdbc:microsoft:sqlserver://pegasrv:1433;tds=8.0;lastupdatecount=true</connection-url>
<driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>
<user-name>peguser</user-name>
password
</local-tx-datasource>
7. Then I copied this file along with the portal.sar file into the E:\server\jboss\default\deploy directory of the AS.
8. Then I started the run.bat file in the E:\server\jboss\bin
9. The server got started, now I pointed the browser to http://localhost:8080 and saw the server console
10. Now I pointed the same to http://localhost:8080/portal and i got the http -500 error.
>From Bundled version jboss 2.4 portal +AS
1. First I downloaded the bundle and unzipped the same to E:/Server/. Then renamed the same E:/Server/jboss.
2. Then I set the environmental variables as follows;-
PATH: C:\Java\jdk1.5.0_08\lib; E:\Server\jboss\lib;
CLASSPATH: C:\Java\jdk1.5.0_08\bin; E:Server\jboss\bin;
JAVA_HOME: C:\Java\jdk1.5.0_08
JBOSS_HOME: E:\Server\jboss
3. Then I created a SQL Server Data base instance in another system and granted rights for me. The db details are host:pegsrv; username: peguser ; password: password.
4. Then I copied the jdbc driver files pertaining to Sql server i.e, msbase.jar, msutil.jar, mssqlserver.jar into the E:\server\jboss\default\lib directory of the AS.
5. Then I configure the portal-sqlsdrver-ds.xml file as follows
<?xml version="1.0" encoding="UTF-8"?>
<local-tx-datasource>
<jndi-name>PortalDS</jndi-name>
<connection-url>
jdbc:microsoft:sqlserver://pegasrv:1433;tds=8.0;lastupdatecoun
t=true </connection-url>
<driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver
</driver-class>
<user-name>peguser</user-name>
password
</local-tx-datasource>
</datasources
Then I configure the following xml files in the default/conf directoy of the server. The standardjaws.xml file is configured with Hypersonic database by default. So I configured JBoss server with MS SQL Server database modify /server/default/conf/standardjaws.xml configuration file. Set
and <type-mapping> elements. java:/MSSQLDS</datasource
<type-mapping>MS SQLSERVER2000</type-mapping>
The standardjbosscmp-jdbc.xml configuration file is configured with Hypersonic database.
So i configured JBoss server with MS SQL Server modify /server/default/conf/standardjbosscmp-jdbc.xml configuration file. Set
and <datasource-mapping> elements. <jbosscmp-jdbc> java:/MSSQLDS <datasource-mapping>MS SQLSERVER2000</datasource-mapping>
</jbosscmp-jdbc>
Then I modified the login-config.xml configuration file with MS SQL Server
database settings. Added the following
<application-policy/> element to login-config.xml. <application-policy name = "MSSQLDbRealm"> <login-module code = "org.jboss.resource.security.ConfiguredIdentityLoginModule" flag = "required"> <module-option name = "principal">sa</module-option> <module-option name = "userName">sa</module-option> <module-option name = "password"></module-option> <module-option name ="managedConnectionFactoryName"> jboss.jca:service=LocalTxCM,name=MSSQLDS
</module-option> </login-module> </application-policy>
By modifying the mssql-ds.xml, standardjaws.xml, standardjbosscmp-jdbc.xml and login-config.xml the JBoss 4.0 server is configured to be used with a MS SQL Server database.
With the embedded hypersonic database it too worked fine, but when I configured my dbase for the bundled version, I am getting the below error
HTTP Status 500 -

[Management, JMX/JBoss] - Multiple depends
by jactor
I am trying to develop a service which is using a stateless session bean (EJB3). So I am dependent of this bean, but this bean is dependent on a persistence unit which seems to be deployed.
ObjectName: jboss.j2ee:jar=concept.jar,name=EntityServiceBean,service=EJB3
| State: NOTYETINSTALLED
| I Depend On:
| persistence.units:unitName=proof
|
Even though this ejb is dependent on a persistence unit, it's visible as a service in the jmx console. This result in my service being started but it is unable to look up the ejb as this needs the persistence context.
I would like my service to be dependent on the persistence unit as well so that it would not get started without its resources available. How do I say that an MBean is dependent on several other beans?
In my jboss-service.xml; do I use several depends-tags, list then in a comma seperated way inside the tag, or something else?
