[JBoss jBPM] - Re: why
by simonbaker
I see your points. I just learn better top-down, starting with the intent of the code, then checking the implementation. Sometimes implementations have side effects that aren't relevant to the API, you need the designer's intent to really know what's important. I'm sorry if you feel it clutters up the forum. I guess I'm a minority of one. But potentially these threads could help others get up to speed faster, make jBPM more popular, yada.
I disagree the persistence behavior of JbpmContext is obvious. I think kuk's statement "opening a JbpmContext opens a session in a transaction if one is configured or already running" deserves some discussion.
Maybe we just need a separate forum for jBPM users who want to chew the fat about how it works as opposed to the more troubleshooting oriented inquiries. I might get lonely there though...
But please know -- I am reading my eyes off and doing my homework, there's just a heck of a lot to cover.

[JBoss jBPM] - Re: JBPM 3.2 - Mailing process - Exception during deployment
by JBossCompBoy
I am trying to get the JBPM mail process working. I believe I have done what was suggested above. I have put a jbpm.cfg.xml file in my EAR root. This seams to work, because it finds the correct hibernate config file. I have also placed a jbpm.mail.properties file in the EAR root. The problem is that the MailAction behaves as if it does not see my properties file. It continues to try to connect to localhost. I will include my jbpm.cfg.xml, jbpm.mail.properties, and the stack trace showing that it is still trying to connect to localhost. If anyone has a clue about this, please let me know.
First the jbpm.cfg.xml
| <jbpm-configuration>
|
| <jbpm-context>
| <service name="persistence">
| <factory>
| <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">
| <field name="isTransactionEnabled"><false/></field>
| </bean>
| </factory>
| </service>
| <service name="tx" factory="org.jbpm.tx.TxServiceFactory" />
| <service name="message" factory="org.jbpm.msg.db.DbMessageServiceFactory" />
| <service name="scheduler" factory="org.jbpm.scheduler.db.DbSchedulerServiceFactory" />
| <service name="logging" factory="org.jbpm.logging.db.DbLoggingServiceFactory" />
| <service name="authentication" factory="org.jbpm.security.authentication.DefaultAuthenticationServiceFactory" />
| </jbpm-context>
|
| <string name="resource.hibernate.cfg.xml" value="jbpm.hibernate.cfg.xml" />
|
| <string name="resource.parsers" value="org/jbpm/jpdl/par/jbpm.parsers.xml" />
|
| <string name="jbpm.mail.templates" value="jbpm.mail.templates.xml" />
| <string name="resource.mail.properties" value="jbpm.mail.properties" />
| </jbpm-configuration>
|
Second, the jbpm.mail.properties file
| mail.smtp.host=cosmail01.com
| mail.smtp.port=25
| mail.smtp.auth=false
| mail.smtp.ssl=false
| mail.smtp.user=nobody
| mail.smtp.password=none
|
Finally the Stack Trace

[JBossCache] - Re: Can TreeCache do what I need?
by manik.surtani＠jboss.com
It is best that you go thru the docs and set up your system accordingly, and then post specific tuning questions here rather than an all-encompassing discussion.

I presume you mean the CacheLoader here. CacheLoaders can use a variety of backing stores to offload cache data to disk, although this isn't a "temp" space. Flushing to a CacheLoader can happen synchronously (this is the default).
I'm presuming you have an external data store (such as a database) where you obtain your data, and use the cache as an im-memory store for cheap/easy access? If not (i.e., you use the cache loader to persist state to a shared DB) you could chain cache loaders:
1) Use a local disk based cache loader (such as Oracle's Berkeley DB or jdbm Cache Loader) in sync mode (immediate flushes)
2) JDBCCacheLoader pointing to your DB, in async mode.
