Migration Problem - intermittent database access
I'm currently migrating an application from JBOSS 4.0.0DR3 to JBOSS 4.0.4.GA, and am having intermittent problems with database access on the new version - some parts of code manage to get the connection successfully while other parts (which use the same method to get a connection) have the connection closed by the CachedConnectionManager. The output in this case is as shown below
Code used to get connection (sometimes works)
--------------------------------------------------
public static Connection getDBConnectionByNaming() throws SQLException
{
Connection conn=null;
opens++;
System.out.println("DBConnection: Opens " + opens);
try
{
if (NAMING_CONTEXT ==null){
NAMING_CONTEXT=PropertyManager.getProperty Constants.DB_NAMING_CONTEXT);
}
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(NAMING_CONTEXT);
conn = ds.getConnection();
}catch (NamingException ex)
{
System.out.println("DBConnection: Naming Exception");
ex.printStackTrace();
} catch ( Exception e ) {
System.out.println("DBConnection: N** Exception");
e.printStackTrace();
}
return conn;
} // end getDBConnectionByNaming()
JBOSS output on error
