SQL & PL/SQL

hi..good evening to all...

I have total 7 java classes which i have to compile and put in the database schema. those 7 classes are interdependent on each other thats why there is a particular order of execution.

i want to compile and put them in the schema thorugh the command line.

i have tried doing this one by one by executing the following command in cmd...

D:\>loadjava -u username/password@sid -v -resolve javaclassname.java
then its working fine..

But i have to do this in one time i.e i have to compile and put all the 7 classes in schema by a single command.
Thats why i have put all the 7 classes one by one in the required order...save the file as 'java_sources.java' and then run the following command...

D:\>loadjava -u username/password@sid -v -resolve java_sources.java
but it is not working... :(

please help...thanks in advance
