Subject [jira] Created: (DERBY-62) TableName not serializable
Date Tue, 09 Nov 2004 21:40:23 GMT
TableName not serializable
--------------------------

         Key: DERBY-62
         URL: http://nagoya.apache.org/jira/browse/DERBY-62
     Project: Derby
        Type: Bug
  Components: SQL  
    Reporter: Dain Sundstrom


I'm not sure how, but sometimes an EmbedSQLException can hold on to a TableName.  Since TableName
is not serializable we can not ship derby exceptions to remote clients.  It is common usage
for EJB applications to simply pass exceptions through to remote clients.

This is the exception I get when I try to serialize an EmbededSQLException... sorry this is
not much help on what is causing EmbededSQLException to hold onto a table name but Java Serialization
doesn't throw nice exceptions.
