Login error with correct u/p using Oracle Application Server / BPEL

Question

Hello,
We are using Oracle 11g and BPEL 10.1.3.4. We had everything working fine until earlier this week. We were receiving an exception when accessing the database from our BPEL process.
Unable to establish connection to "iCareConnectionPool". Error message: Exception occurred testing connection. Exception: java.sql.SQLException: ORA-01017: invalid username/password; logon denied.
I went into the Application Server control and tested the data source and connection pool and they both failed with the login error. The userid and password being submitted is correct. I checked the data-source.xml file and the id/password looked good. Here are the steps I performed.
On BPEL server:
1)     Deleted connection pool iCareConnectionPool, data source, iCareDataSource, and removed /eis/db/iCareDataSource from the DBAdapter.
2)     Created new connection pool – iCareConnectionPool using jdbc:oracle:oci:@//<host>:1521/ORCL with userid IDS
3)     The connection pool test was successful. Clicked finish to create connection pool
4)     From the JDBC resources screen, I tested the connection pool and it failed with invalid logon error.
5)     Modified connection pool to use IDS2 and it worked.
6)     Modified connection pool to IDS and it failed.
7)     Modified connection pool to jimc and it worked.
On Database:
1)     Created new schema/user ICAREIDS
2)     Connected using SQL Developer and I could connect
On BPEL Server:
1)     Deleted connection pool
2)     Created connection pool iCareConnectionPool using jdbc:oracle:oci:@//<host>:1521/ORCL with userid IDS
3)     The connection pool test was successful. Clicked finish to create connection pool
4)     From the JDBC resources screen, I tested the connection pool and it failed with invalid logon error.
5)     Modified connection pool to use IDS2 and it worked.
6)     Created new connection pool TestPool – same results
7)     Tried jdbc:oracle:thin:@//<host>:1521/ORCL - same results
On my local system BPEL server:
1)     Created connection pool iCareConnectionPool using jdbc:oracle:oci:@//<host>:1521/ORCL with userid IDS
2)     The connection pool test was successful. Clicked finish to create connection pool
3)     From the JDBC resources screen, I tested the connection pool and it failed with invalid logon error.
4)     Modified connection pool to use IDS2 and it worked.
5)     Modified connection pool to use ICAREIDS and it failed.
Since it failed on two different BPEL server's, I am wondering if it is something with the database. I can connect using existing schema's but not IDS or any new schemas. However, I can connect to any schema using any other tool like SQL Developer.
Can anyone provide an insight as to what could be happening here.
Thanks,
Jim

I found the problem and wanted to pass on the solution in case any one else runs into this problem.
With Oracle Database 11g the passwords are now case sensitive. Because the BPEL server is using 10g drivers the login fails if you have capital letters in your password.
