    Jboss Warnings Questions

    fredrich Newbie

      Hi gurus,

      I have few questions :

      1).Every time I start JBoss 3.2.2, I get the following warnings:

      a).1 warning. [TxConnectionManager] Prepare called on a local tx. Use of local transactions on a jta transaction with more than one branch may result in inconsistent data in some cases of failure. this error shows up when MDB does some action(such as: updating database). I have specified a 'Required' transaction attribute but useless.
      I don't understand what is meant by 'branch'. The MDB only have ONE method, onMessage. I use Mysql/InnoDB 4.x, and as far as I know, Mysql support transaction.

      b).1 warning. [Heartbeat] Heartbeat disabled
      I'm afraid that JBoss is dying. :-)

      c).1 warning. [JkMain] No properties file found E:\jboss-3.2.2\server\default\conf\jk2.properties

      d).5 warnings. [EmbeddedTomcatService] Unable to invoke setDelegate on class loader:org.jboss.web.tomcat.tc4.WebCtxLoader.
      yes, there are FIVE warnings like this.

      Can those warnings cause something bad, such as server crash, or bad performance or something else? How to eliminate those warnings ? (for example : changing the standardjboss.xml or jbosscmp-jdbc.xml or other things)

          MySQL does not support 2 phase commit protocol.

          Can be ignored.
