Re: Tomcat 8 and Oracle Wallets
Hi Luis,
Thank you very much for the hint. I wasn't able to export the Oracle Wallets
due to not knowing the password the DBA put on it.
However, I was able to obtain the original JKS from which the Oracle Wallets
were created from.
I removed all edits I made in setenvs.sh and worked purely with the
context.xml:
1. Add the following jar files in lib/ of Tomcat:
ojdbcx.jar (x = relevante major versie van Java, vbl: 8)
2. In ./jre/lib/security/java.security add the following:
security.provider.10=oracle.security.pki.OraclePKIProvider
3. In context.xml:
-
url="jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCPS)(HOST=)(PORT=2484)))(CONNECT_DATA=(SERVICE_NAME=< SERVICE
NAME >)))"
-
connectionProperties="javax.net.ssl.trustStore=./keystores/oracle_keystore/mykeystore.jks;javax.net.ssl.trustStorePassword=changeme;javax.net.ssl.trustStoreType=JKS;javax.net.ssl.keyStore=./keystores/oracle_keystore/mykeystore.jks;javax.net.ssl.keyStorePassword=changeme;javax.net.ssl.keyStoreType=JKS;"
Now it works!
Regards,
Christophe

Hello Christophe,
Very interesting, thanks!
Would it be possible in your scenario to export the certificates from the
wallet and import them to a different keystore (PCKS12 or JKS)? You can
have a look at [1]
Hope it helps,
Luis

So I think this means that the problem lies somewhere between Tomcat and
the OJDBC driver.

Subject: Tomcat 8 and Oracle Wallets
Hello,
I'm having an issue with setting up SSL encrypted connections to an Oracle
database.
I looked up on many websites and places and got the impression that either
people abandon setting up the encryption or implemented the connection in
code rather than through the jndi context in Tomcat itself.
Tomcat 8.5.34
JDK 1.8.0_171
RedHat 7.4 (Selinux permissive)
OracleDB 12.2.0.1.0
I've written a simple Java application which just connects to the database
using TCPS and makes a simple query.
This works.
java -D oracle.net.tns_admin ="./oracle_wallets/" -D
oracle.net.wallet_location ="(SOURCE=(METHOD=FILE) (METHOD_DATA =
(DIRECTORY=./oracle_wallets)))" -cp ./: ./lib/ ojdbc8.jar :./lib/
oraclepki.jar DataSourceSample
I'm using the official ojdbc8.jar from Oracle appropriate for the version
of Java and the Oracle database.
Because Oracle Wallets is an invention of Oracle itself, I added the
appropriate security provider in java.security:
security.provider.4=oracle.security.pki.OraclePKIProvider ( loaded before
com.sun.net.ssl.internal.ssl.Provider ) so it gets loaded before the
default PKCS implementation in Java.
cwallet.sso cwallet.sso.lck ewallet.p12 ewallet.p12.lck sqlnet.ora
tnsnames.ora are all placed inside the ./oracle_wallets.
As said before, the little Java app that I wrote is able to open the
wallets and connect to the database:
AArray = [B@6328d34a
AArray = [B@145eaa29
AArray = [B@15bb6bea
Driver Name: Oracle JDBC driver
Driver Version: 12.2.0.1.0
Default Row Prefetch Value is: 20
Database Username is: MY_USER
82062920015 SomeResults1
87093009324 SomeResults2
74031825702 SomeResults3
I translated this to Tomcat in the following way:
I placed the ojdbc8.jar and oraclepki.jar in the libs folder of Catalina.
I added the Java options in bin/setenv.sh:
export CATALINA_OPTS="$CATALINA_OPTS -Doracle.net.tns_admin=/oracle_wallets/"
export CATALINA_OPTS="$CATALINA_OPTS
-Doracle.net.wallet_location='(SOURCE=(METHOD=FILE) (METHOD_DATA =
(DIRECTORY= /oracle_wallets)))'"
The entries in the context.xml file look like this:
I can confirm that the rights on the filesystem for the wallets are
permissive enough for Tomcat to read them.
Tomcat is able to connect to the database.
But for some reason it's as if it's unable to read the wallets.
Caused by: oracle.net.ns.NetException: The Network Adapter could not
establish the connection
at oracle.net.nt.ConnStrategy.execute
