Hi, We use testDesc = StructDescriptor.createDescriptor("descName", dbConnObj); on Websphere using IBM's connectionPooling. This works fine without any issues, if we use the DriverManager for the datbase connection. Using IBM's connectionPooling, it gives some rrors with OracleConnectionProxy. Is it a bug with Oracle on Websphere app server? Would appreciate if someone can give me a lead on this. Thanks,
