* [Pljava-dev] Issue with SunMSCAPI jar file @ 2010-03-29 21:44 0 siblings, 1 reply; 3+ messages in thread From: @ 2010-03-29 21:44 UTC (permalink / raw) I'm testing out the 1.4 PL/Java version. In the code we're invoking from Postgres, there is a setup for SSL. The whole thing runs normally outside of Postgres. However within Postgres, it gives the error: ERROR: java.lang.NoClassDefFoundError: Could not initialize class sun.security.mscapi.SunMSCAPI On the surface of it, this means sunmscapi.jar not found. But I did add this jar file to the classpath. In any case, it is at the normal location in the JRE installation, and since the jvm.dll from the JRE is in the system path and seen by pl/java (simple calls without the SSL part work fine), I assume it sees the file sunmscapi.jar as well. I notice that many times, the error in PL/Java is not exactly the underlying cause. For example when it says pljava.dll not found, it in fact means jvm.dll is not found, and pljava.dll can't be initialized. So I suspect it's something similar here. But without a more detailed error message, I'm not sure how to go about a fix. Maybe sunmscapi.jar is making use of some services that can't be found or initialized? Any idea?

* [Pljava-dev] Issue with SunMSCAPI jar file @ 2010-03-30 18:23 parent: 0 siblings, 0 replies; 3+ messages in thread From: @ 2010-03-30 18:23 UTC (permalink / raw) Hi Thomas, I think it's likely something in the initialization of MSCAPI that failed. It turns out MSCAPI is just one of the many cryptographic providers for Java (it's last in the list actually). So I commented it out (in java.security), and the error is gone. SSL is still ok. By doing this I probably lose out some functionalities (MS crypto library?) but for the time being it works for me. By the way I'm not sure about what you said regarding javaU. If only untrusted Java can open sockets and access files, that seems counter-intuitive to me. My code to open sockets has 'java' as the language, and it seems to work just fine.

Perhaps an external access is attempted when this happens? PL/Java will prevent the process from opening sockets and access files in the file system unless you run it as a non trusted ( javaU ) language.
