Do any of you (more experienced folks especially) know if MIME Multipart emails can be sent via JBossESB EmailWiretap, and if this MimeMultipartProvider can be used to send them? Or if there's another approach, etc. No info in maunuals, have seen no specific posts, wiki articles or other related stuff. Anyone know: 1. Is it possible to send these via EmailWiretap? 2. What is the right/best/workable approach? -=j=- -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/557970#557970] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [Beginner's Corner] - Standards supported by JBoss AS vs JBoss EAP

EAP 5 is pretty much AS 5.1.0.GA + Seam + various fixes + various config changes (security lock-down) and a lot more testing. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/557952#557952] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [JBoss Cache] - JBoss Cache as a standalone service

Navin Surtani [http://community.jboss.org/people/navssurtani] replied to the discussion "JBoss Cache as a standalone service" To view the discussion, visit: http://community.jboss.org/message/557950#557950 -------------------------------------------------------------- I may not be understanding your problem properly. I am on the #infinispan channel on FreeNode IRC. I have a feeling it would be a lot easier if we just spoke in real time and I can help you out where possible. I think that if you have a CacheManager instance in each app with the same cache name (String) registered to each CM; your caches will be synchronised. This will work as long as long as you use the *same* configuration for each Cache instance. But again, we could be barking up the wrong tree if I don't understand your problem properly. So, if you could find me on IRC would be great. I'm generally online from about 0900GMT up until 1800GMT roughly. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/557950#557950] Start a new discussion in JBoss Cache at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

String imageName = processDefinition.getImageResourceName(); InputStream imageInputStream = repositoryService .getResourceAsStream(processDefinition.getDeploymentId(), imageName); Second you could get activityCoordinates from repositoryService.

[JBoss Messaging] - Negative MessageCount

by Noa Drach

Noa Drach [http://community.jboss.org/people/newway] created the discussion "Negative MessageCount" To view the discussion, visit: http://community.jboss.org/message/557928#557928 -------------------------------------------------------------- We have a part in my code that queries a queue once in an hour to get it's size. this is the code e used MBeanServer mBeanServer = MBeanServerLocator.locateJBoss(); ObjectName serverObjectName = new ObjectName("jboss.messaging.destination:service=Queue,name=" + queueName); Integer messagesInQueue = (Integer) mBeanServer.getAttribute(serverObjectName, "MessageCount"); return messagesInQueue.intValue() ; and we keep the data in the DB. from looking into the data kept we see that sometimes we receive negative values. in https://jira.jboss.org/browse/JBMESSAGING-926?focusedCommentId=12356514&p... https://jira.jboss.org/browse/JBMESSAGING-926?focusedCommentId=12356514&p... We saw a discussion about this issue but it describes a scenario of calling removeAllMessage. In our case we don't interfere with the queues work messages are sent by the producer and handled by the receivers. we are using Messaging 1.4.5.GA I have 2 questions: 1. Is there an explanation for the negative values? 2. Can We trust the values given when they aren't negative?

Re: [jboss-user] [Beginner's Corner] - JDBC inside CMT

by Wolf-Dieter Fink

Wolf-Dieter Fink [http://community.jboss.org/people/wdfink] replied to the discussion "JDBC inside CMT" To view the discussion, visit: http://community.jboss.org/message/557915#557915 -------------------------------------------------------------- Ok, if you are using a DataSource and set explicit autocommit the result after return connection into the pool might be surprisingly because the connection will be reused. We have some trouble in the past with 'non standard' solutions, it will become difficult in case of app-server upgrade or code changes. But if I understand your scenario correct you do only some SELECTs vie JDBC, right? If so, there is no necessity for autocommit. I use JDBC also within CMT beans, I'll leave the connection unchanged and delegate the rollback to the container. If a RuntimeException is thrown the container rollback for you. If an Exception should thrown I force the rollback via <context>.setRollbackOnly() So I prefere a transactional MDB and throw an Exception to rollback or delegate to a SLSB with Tx=RequiresNew. Remember that all entity access must have a transaction, if no available the container will open one explicit (this can cause less performance) -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/557915#557915] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[Beginner's Corner] - Why am I still seeing the HouseKeepingMessage ?

by Mads Moelgaard Andersen

Mads Moelgaard Andersen [http://community.jboss.org/people/mda_dk] created the discussion "Why am I still seeing the HouseKeepingMessage ?" To view the discussion, visit: http://community.jboss.org/message/557907#557907 -------------------------------------------------------------- Hi I keep getting this "HouseKeeping" message for both connections and statements. and I don't understand why. All my JDBC calls follow the same pattern: public ArrayList<ObjectScore> getObjectIdsAndScore(long someLong, long anotherLong, long aThirdLong, String aString) throws Exception { ArrayList<ObjectScore> result = new ArrayList<ObjectScore>(500000); ResultSet rs = null; try { Connection conn = getConnection(); StringBuffer sql = new StringBuffer(); *** BUILDING SOME SQL *** rs = executeSelect(conn, sql.toString(), fetchsize); rs.beforeFirst(); while (rs.next()) result.add(new ObjectScore( rs.getLong(1), rs.getFloat(2))); result.trimToSize(); } catch (Exception e) { logger.error("getObjectIdsAndScore failed: "+e.getMessage()); throw e; } finally { try { if (rs.getStatement() != null) rs.getStatement().close(); } catch (Exception ignored) { } try { if (rs != null) rs.close(); rs = null; } catch (Exception ignored) { } closeConnection(); } return result; } Both getConnection() and closeConnection() are inherited methods. public ResultSet executeSelect(Connection connection, String sql, int fsize) throws Exception { ResultSet rs = null; try { sql = (sql.endsWith(";") ? sql.substring(0, sql .length() - 1) : sql); logger.info("SQL: " + sql); Statement statement = connection.createStatement( ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY); statement.setFetchSize(fsize); rs = statement.executeQuery(sql); } catch (Exception e) { logger.error("executeSelect failed: "+e.getMessage()); throw e; } finally { } return rs; } As you can see the first snippet opens and closes the connection. The second creates both the statement and the resultset where the first closes them both. Still I get WARNs like 14:01:47,320 WARN [WrappedConnection] Closing a result set you left open! Please close it yourself. java.lang.Throwable: STACKTRACE at org.jboss.resource.adapter.jdbc.WrappedStatement.registerResultSet(WrappedStatement.java:744) at org.jboss.resource.adapter.jdbc.WrappedStatement.executeQuery(WrappedStatement.java:217) Pointing out the method for the first snippet. I also get following when a MDB exits the onMessage method. [CachedConnectionManager] Closing a connection for you. Please close them yourself: org.jboss.resource.adapter.jdbc.WrappedConnection@844674 I've already read http://community.jboss.org/wiki/WhatDoesTheMessageDoYourOwnHousekeepingMean http://community.jboss.org/wiki/WhatDoesTheMessageDoYourOwnHousekeepingMean and I guess my code pretty much follow the outlined pattern, so what is wrong?
