[ewg] Java use SDP problem

[Nimrod Gindi]

Hi,

Can you share some more set up info?

Which OFED build are you using? What is your conf file content? Which
JVM being used? What is you Java application?

 

Feel free to reply directly to me and I'll assist you with it.

 

I saw such things with incorrect configured conf file and older OFED
versions.

Hi,guys!

    I am trying to use netperf to measure the bandwidth of SDP. First, I
modprobe libsdp and addd LD_PRELOAD=libsdp.so before the
application,such as "LD_PRELOAD=libsdp.so netserver" and
"LD_PRELOAD=libsdp.so netperf  -H 10.5.0.171", all this work and I get
the right results.

   But When I use my Java Application to test, such exceptions are
reported:

java.net.SocketException: Network is unreachable

        at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333)
