Hi,

here you can find jvpp (java API) documentation:
https://git.fd.io/vpp/tree/src/vpp-api/java/Readme.txt

and some examples:
https://git.fd.io/vpp/tree/src/vpp-api/java/jvpp-core/io/fd/vpp/jvpp/core/examples

For more, take a look at hc2vpp project which is using jvpp
https://git.fd.io/hc2vpp/tree

Regards,
Marek

Hi Holoo,



There are two great pages explaining how to use the vpp C and python APIs:

C: https://wiki.fd.io/view/VPP/How_To_Use_The_C_API

python: https://wiki.fd.io/view/VPP/Python_API

I believe you can also use java or lua if you wish.

Hello
I am working on VPP and now need to use its API to communicate with it.
I want to know how I can use its API?? Is there any example in source code or 
any where else? (if yes, how should I use it?)
thanks in advance

Re: [vpp-dev] VPP API Test Crash - Need help debugging

[Keith Burns]

Billy,

Apologies, that was a convenience I did for the attendees of the devboot
course last year.

In the course notes I had the git checksum of the commit, but as Dave
points out, a bit stale.

I find a combo of "ldd" against the VPP binary you have built and
ultimately want to install and "ldconfig -p | grep" to be useful. Grep
against "vpp" and "vlib" tends to show what's hanging around and the diff
usually is defunct jetsam from prior packaging.

Be a little careful though as I don't believe vlib is unique to VPP/fdio

As the project evolves , so too packaging (I've felt your pain)

A "find" over /usr/include for headers is not a bad sanity check too

Dear Billy,



Looks like a stale tree...



vm = vlib_mains[os_get_cpu_number ()] from within vpp_api_test was always a
mistake. I cleaned this up a while ago. Vpp_api_test was spuriously linked
against libvlib.so, leading to this very crash in vpp_api_test until I
cleaned up the set of libraries, etc.



Please update, “make distclean”, rebuild, and reinstall. If that doesn’t
fix it, please unicast me.



Thanks… Dave

I have screwed up my system and need some help fixing. Long email because
of the traces, so quick summary up front.



I was playing with pluggins and had some notes from over the summer on
running the MacSwap pluggin. I downloaded the code via:

  git clone https://github.com/alagalah/macswap-plugin



The code did not compile initially because the pluggin registration code
changed from a function call to a MACRO. I fiddle with the code and got it
to compile and install. As soon as I fired up VPP it crashed. I did not
collect the output (sorry), but in the mean time I found the sample pluggin
on the Wiki and figured it was the better route anyway. So I deleted the
all macswap*.so files I could find under /usr/* and deleted my local
sandbox with the MAC Swap changes. Now when I run VPP, it crashes, even a
recent, clean sandbox. Builds and loads fine. But when I "show
interfaces", vpp_api_test crashes (see below).



Is there something in the pluggin registration that needs to be cleaned up
that I am missing? Running on Fedora 25. Recent builds on my CentOS system
work as expect, so this most likely has something to do with how I
installed and more likely how I deleted the MAC Swap pluggin on my laptop.



Any help would be greatly appreciated,

Billy McFall
