Java Web Start (Unable to download dependency jars using JNLP)

Pankaj ShakyaMay 4 2017 — edited Jan 17 2018

I am trying to implement Digital Signature using bouncycastle. Previously i was using applet which runs inside browser, but now as firefox and chrome are no longer supporting NPAPI plugin.

Thats why i tried to implement this by using JNLP. But while i am running JNLP file, following exceptions are being displayed....

Reading the certificates for [TEST IIIB SIGN ENCRY - -2073519335 - -2073519335]

Certificate found for serial number [1396617742]

Works ok in my environment (note I'm using python 2.5).

-----
$ ipython

Q: what is the output if you do:

type(connection_string)


?

type(connection)

I asked for connection_string, not connection. Also I'm assuming you're running it in the same python session you run the previous code you show us. Is that right?

Here is the code.....

I am doing all this under the same python session.

Since I was unable to find out what is happening, I forwarded your problem to the cx-oracle-users list. You can find an answer over there. Here's [the link|http://sourceforge.net/mailarchive/forum.php?forum_name=cx-oracle-users&max_rows=25&style=nested&viewmonth=200812&viewday=19].

I encountered this problem today, and there was no answer on the web.
This is what I learned, although it is embarassing to admit. I had installed
the Ora11g version of cx_Oracle, but the database is Ora10g. I deleted
the Ora11g cx_Oracle files, installed the Ora10g version, and everything
worked.
