Hi Bernd, On My Ubuntu Machine I am able to compile Intel based Java programs no issue. We have Armv7 target board openjdk installed, able to compile java program and run on the board no issues,
I run the curl command on the armv7 target board, able to connect to https link and get the content, same when I use the program below provided it takes 15 ~20 seconds more using httpsurlconenction. Now I wanted to try out alternative Apache httpclient to check if it can reduce time to connect same https link. I am not able to compile the program, I will provide the details in a while (added jar file for httpcore). So reuested to provide any link or steps Thanks in advance Regards Somshekar C Kadam 9036660538 On Thu, Sep 5, 2019 at 2:30 PM Bernd Eckenfels <e...@zusammenkunft.net> wrote: > Hello, > > Are you able to compile and run any java programs? > > What is the error you are getting, what is the command you are using to > compile it and how does your source directory looks like? > > You can compile the sample client on other machines, if this helps your > development velocity. > > You can’t really compare native program (curl) speed with Java, but it > certainly should not be that different (I mean yes you can, it just does > not tell you much).
