Re: Deploying Multiple beans from a single JAR

[Sundari S]

Hi,   Thanks for that reply. Fortunately, that was the only sensible guess we could make and had tried out the same thing exactly.   But, while deploying the JAR, the exception that we got was :   ------------------------------------------------------- weblogic.ejb.common.DeploymentException: Could not create the persistence store for this bean.; nested exception is:         java.lang.NoClassDefFoundError: weblogic/cmp/rdbms/PSRdbms_Base -------------------------------------------------------   If you have earlier encountered such an error or, you could possibly let me know what it is due to, do mail me. We assumed that the class it is creating is by default placed in the directory structure...weblogic/cmp/rdbms/ and since our file names are modified, this could be a problem. I am new to this and have no idea what this error is due to.   Do let me know, as soon as possible.   Thanks and Regards, Sundari.

I think this could help you. regards sbpodila. ----- Original Message ----- From: Sundari S To: [EMAIL PROTECTED] Sent: Saturday, February 09, 2002 2:37 PM Subject: Re: Deploying Multiple beans from a single JAR Hi,   I think I have slightly missed in specifying explicitly in my questions that I was using Weblogic 5.1 version. Sorry about that.   But, anyway, I am just enclosing the site for weblogic5.1 dtd for rdbms xml file which says  the following :   <!--StartFragment--><!-- The root-level element of an XML file that represents a single bean that is managed by the WebLogic RDBMS Container Persistence Type. --> <!ELEMENT weblogic-rdbms-bean (     pool-name,     schema-name?,     table-name,     attribute-map,     finder-list?,     options? )> http://www.bea.com/servers/wls510/dtd/weblogic-rdbms-persistence.dtd   So, here, there is only one <weblogic-rdbms-bean> element (mani element) for ONE BEAN.   So, in this case, how do I work-around the problem of creating a single jar for all the rdbms accessing beans, in my JAR ??   Do let me know.   Thanks and Regards, Sundari.
