I'm trying to install BC in JBoss.

1) I modified the java.security file to add-
security.provider.1=com.ibm.jsse2.IBMJSSEProvider2
security.provider.2=com.ibm.crypto.provider.IBMJCE
security.provider.3=com.ibm.security.jgss.IBMJGSSP rovider
security.provider.4=com.ibm.security.cert.IBMCertP ath
security.provider.5=com.ibm.security.sasl.IBMSASL
security.provider.6=org.bouncycastle.jce.provider. BouncyCastleProvider

Then by default BC wasn't still installed in JBoss. Although if I ran in Eclipse standalone program, it was installed and it worked.

2) Then I dropped the bcprov-ext-jdk15-146.jar jar file in here C:\Program Files\Java\jre1.5.0_17\lib\ext, then it started working in JBoss.

Is this method safe to do installation, I'm confused here whether to use bcprov-ext-jdk15-146.jar or bcprov-jdk15-146.jar?

I guess, ext provider provides IDEA implementation. To be on safe side, I made my mind to use only bcprov-ext-jdk15-146.jar.

Is this assumption correct?

Yes, the ext directory is the right place to put the provider in a situation like this. It will force it to be loaded by the system class loader.

The assumption about the ext provider is correct, you only need to use it if you're expecting you might use IDEA further down the track.

Does it have anything to do with SSL encryption which is used by default in JBoss server or any J2EE server?

Only provider ordering might affect this, and even then only if the underlying code is not specifically specifying which provider to use.
