[JBoss Cache: Core Edition] - ava.lang.ClassCastException: java.lang.ClassNotFoundExceptio

by northgorky

reetings. This starts as a database error in an EJB (a new Database Table can't be found -- I messed up in my Database somewhere). But the then the JCache gets into some kind of weird state, and you can't get ANYTHING out of it, taking down the entire application. Get ClassCastExceptions and ClassNotFoundExceptions on any Cache Access after this point (some are attached). The ONLY way I have found to recover so far is to cold start JBoss, as all access from all clients are failing at this point. This also happens when a Servlet exception occurs when the Cache is being accessed (and/or updated). I can generate and post the Servlet crash stack trace as well. Oh yeah, versions; Jboss-4.2.2.GA JCache: 1.4.1.SP5 JDK: "1.5.0_11 steve@system:/usr/local/java/jboss-4.2.2.GA> java -jar server/hrx/lib/jboss-cache-jdk50.jar Version: 1.4.1.SP5 Codename: Cayenne CVS: $Id: Version.java 4510 2007-09-26 18:45:19Z manik.surtani(a)jboss.com $ History: (see http://jira.jboss.com/jira/browse/JBCACHE for details) steve@system:/usr/local/java/jboss-4.2.2.GA> java -version java version "1.5.0_11" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03) Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing) Due to an application constraint, only one Thread would be accessing (Read or Write, and mostly read) any given node at any time. So I've reduced locking as much as possible (I hope). Stacktrace can be found at; http://j2eeguys.com/~steve/JBoss/JCacheCrash.txt Current config file can be found at; http://j2eeguys.com/~steve/JBoss/hrx-session-cache-service.xml Let me know if you need more details. Log is attached. Not sure what else is needed. I can even be persuaded to come out to Atlanta, if that would be helpful.

[Advanced Documentation] - 4yr old Oracle Datasource Examples misleading with latest Tr

by northgorky

Greetings. The sample oracle-ds.xml files should have a comment in them that the XA samples would be better in most conditions. The DS samples will only support ONE datasource in a transaction at a time. Any attempt to connect to two separate Oracle (or other non-XA datasource) at the same time will fail. This is in the DataSource samples for 4.2.2.GA, as well as JBoss 5.0.0.Beta4. It would probably be a good idea to add a line along the lines of;  NOTE: The Wiki's are also out of date and confusing for this topic. (Another thread). Should I open a JIRA Issue on the examples? -Steve View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138180#4138180 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4138180

[JBoss Portal] - Re: content rendering in minimize mode

by julien＠jboss.com

it's an optimization :-) otoh we could have metadata in jboss-portlet.xml that would say whether a portlet needs to be rendered for a minimized mode like | <render-on-minimized>true</render-on-minimized> | "PMN" wrote : For some reason I understood that it should be possible to write content in Minimized mode, especially to render a minimized mode such as a project meteo. | | I am using 2.6.3, the processDispatch() method is called in minimized mode but the content is not rendered - only teh decoration is .... | | Is this a bug or a feature ?

by julien＠jboss.com

in 2.6.x you have a configuration that is flexible, read the manual http://docs.jboss.com/jbportal/v2.6.4/referenceGuide/html/errorhandling.html View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138174#4138174 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4138174

[JBoss Getting Started Documentation] - The Wiki page for configuring Oracle is misleading

by northgorky

Greetings. I tried posting this in the Getting Started Documentation section, but that did not really seem to work (was ignored). The Wiki page for configuring Oracle is, to put it mildly, misleading. The way it is laid out, it implies that local-tx datasources are what should be used for Oracle Databases. This might have been correct for Oracle 8 and before, but is definitely not the case for Oracle 10 & later. The page I am concerned about is; http://www.jboss.com/wiki/Wiki.jsp?page=SetUpAOracleDatasource Proposed correction attached. I can upload if you would like, or post a revision (or if somebody wants to update, go ahead). The major change was to add a few statements just before the sample Datasource files, and to switch the order the Datasource Examples are given in the document. This should help cut down on the number of Transaction Manager complaints as well, I would think. (Would have eliminated them from me, anyways). Can't seem to attach files here, so put my suggested fix up on my webserver. Link is http://j2eeguys.com/~steve/JBoss/SetUpAOracleDatasource.html.

[JBoss Portal] - Re: content rendering in minimize mode

by chris.laprun＠jboss.com

The current implementation does not render anything in minimized mode. If you feel that portlets should be given the opportunity to render something, please file a feature request in JIRA.

[Clustering/JBoss] - Re: role of port bindings xml

by bstansberry＠jboss.com

You can see who the members of a cluster are by looking at the jboss:service=DefaultPartition mbean in jmx-console. Except, replace "DefaultPartition" with whatever you set with -g. Re: your JMS issue, I'm guessing someone is looking up a ConnectionFactory from the wrong cluster; i.e. a config issue in someone's naming properties.

[EJB 3.0] - Re: Datasource not bound doing JPA outside of container

By the way you'll notice my datasource name switches between MyDS and CobraShadowDS, I was trying to change the name to make it simpler but I missed a spot, sorry :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138151#4138151 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4138151
