Import .pde file on PL/SQL Developer

As far as I know, Import/Export and Data Pump are command-line-only types of tools. But if you really wanted to use that functionality from within SQL Developer (or SQL Plus), Data Pump uses the built-in DBMS_DATAPUMP and DBMS_METADATA packages. You should be able to call those packages directly, so I would start there. There's documentation available in the Oracle® Database PL/SQL Packages and Types Reference on both of them (DBMS_METADATA and DBMS_DATAPUMP).

Use following statement to see what is exactly in export file:

imp sreeni/sreeni@agentrics1:1524/ezmodc file=SreeniTrunkDump.dmp indexfile=SreeniTrunkDump.sql full=y

This statment will not try to import data, just dumps DDL to indexfile. Check the generated file to see if table is in export.

Alternatively if you are on unix

strings SreeniTrunkDump.dmp|grep <missingtable>

If table is in export file something goes wrong during import. Missing tablespace for example. Check the logfile of import statement (BadriSchemaImport_Import.log) for that.
