[ANNOUNCEMENT] HttpComponents Core 4.4.12 Released
The Apache HttpComponents project is pleased to announce 4.4.12 GA
release of HttpComponents Core.
This is a maintenance release that corrects a number of defects
discovered since release 4.4.11.
Please note that as of 4.4 HttpCore requires Java 1.6 or newer.
IMPORTANT: Users of HttpCore 4.x GA releases are strongly encouraged to
evaluate new HttpCore 5.0 APIs and give the project developers
feedback, share critique or propose changes.

About HttpComponents Core
HttpCore is a set of low level HTTP transport components that can be
used to build custom client and server side HTTP services with a
minimal footprint. HttpCore supports two I/O models: a blocking I/O
model based on the classic Java I/O and a non-blocking, event driven
I/O model based on Java NIO.

Also I tried with higher version httpcomponents-client-5.0-beta5 version
with example given in it.
Same result.

Re: apache httpclient
Posted by Bernd Eckenfels <ec...@zusammenkunft.net>.
Hello,
The sample code expects a truststore file named my.keystore in the current runtime directory with password „nopassword“, you need to provide one it seems. I guess if you use official certificates you don’t need that part of the customization.
The Java keytool command can be used to import certificates into new keystore files.
BTW it might be easier to hire someone with Java experience.
Gruß
Bernd

Hi Bernd and Yossi,
I am not sure what else I need to do on this stuck
Did give the classpath while executing as mentioned by Bernd and Yossi.
somshekar@celsys041:~$ sudo java -classpath
/home/somshekar/Downloads/httpcomponents-core-4.4.12/lib/httpcore-4.4.12.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-4.5.9.jar
ClientCustomSSL

Re: apache httpclient
Posted by Somshekar C Kadam <so...@gmail.com>.
Hi Bernd and Yossi,
I am not sure what else I need to do on this stuck
Did give the classpath while executing as mentioned by Bernd and Yossi.
somshekar@celsys041:~$ sudo java -classpath
/home/somshekar/Downloads/httpcomponents-core-4.4.12/lib/httpcore-4.4.12.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-4.5.9.jar
ClientCustomSSL

somshekar@celsys041:~$ sudo java -classpath

ClientCustomSSL

somshekar@celsys041:~$ pwd
/home/somshekar
somshekar@celsys041:~$ file ClientCustomSSL.class
ClientCustomSSL.class: compiled Java class data, version 52.0 (Java 1.8)

RE: apache httpclient
Posted by yo...@yossi.at.
Your class should also be in the classpath. Add ";path/ClientCustomSSL.class" to your class path.
(This is basic Java stuff, unrelated to HC. Maybe you should do some Java tutorial first, or if possible start using an IDE, which simplifies a lot of these issues.)

RE: apache httpclient
Posted by yo...@yossi.at.
You need to specify the full package name of the main class (in your case org.apache.http.examples.client.ClientCustomSSL).

Hi Yossi,
Thanks you are right, I did put all jar files and compiled it, now it compiles successfully able to create class file.
compile command
javac -classpath
/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpcore-4.4.11.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-osgi-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-cache-4.5.9.jar
ClientCustomSSL.java
somshekar@celsys041:~$ file ClientCustomSSL.class
ClientCustomSSL.class: compiled Java class data, version 52.0 (Java 1.8)
when I try to run it, it gives below error, do I have to specify the classpath at runtime also
somshekar@celsys041:~$ sudo java -classpath /home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpcore-4.4.11.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-osgi-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-cache-4.5.9.jar
ClientCustomSSL
Error: Could not find or load main class ClientCustomSSL
thanks in advance

Re: apache httpclient
Posted by Somshekar C Kadam <so...@gmail.com>.
Hi Yossi,
Thanks you are right, I did put all jar files and compiled it, now it
compiles successfully able to create class file.
compile command
javac -classpath
/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpcore-4.4.11.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-osgi-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-cache-4.5.9.jar
ClientCustomSSL.java
somshekar@celsys041:~$ file ClientCustomSSL.class
ClientCustomSSL.class: compiled Java class data, version 52.0 (Java 1.8)
when I try to run it, it gives below error, do I have to specify the
classpath at runtime also
somshekar@celsys041:~$ sudo java -classpath
/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpcore-4.4.11.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-osgi-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-cache-4.5.9.jar
ClientCustomSSL
Error: Could not find or load main class ClientCustomSSL
thanks in advance

RE: apache httpclient
Posted by yo...@yossi.at.
It seems that you are only putting httpclient-4.5.9.jar in your classpath, but it has dependencies on other JARs itself. Most importantly, it depends on HttpCore, part of the same project. You can see the dependencies, and their own dependencies, recursively, at https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient/4.5.9.
Collecting all the transitive dependencies for Java projects manually can become quite time-consuming. You can definitely do it for this test, but I recommend learning how to use Maven.

Hi Yossi,
Thanks for correcting me, I used example from 4.5.9, let me know if I am
setting proper jar file or need to give any other or missing any step.

RE: apache httpclient
Posted by yo...@yossi.at.
The compilation error are the result of you coping code from HC version 5.0 and using it with JARs for HC 4.5.x. The hint is in the package name (client5).
I suggest you look for examples for the current version (4.5.x).

RE: apache httpclient
Posted by yo...@yossi.at.
One possible explanation for the 20 second delay is that the curl call goes through a proxy (defined by the http_proxy/https_proxy environment properties), while Java does not pick up these properties. If this is indeed the case, you need to pass some system properties in your java call. See the documentation: https://docs.oracle.com/javase/8/docs/technotes/guides/net/proxies.html.

Hi Brenda,
First of all thanks for your time and advice.
I am not asking for Arm, I was telling for Intel Ubuntu Linux machine, not able to get it compiled.

Re: apache httpclient
Posted by Bernd Eckenfels <ec...@zusammenkunft.net>.
Hello,
The URLConnection code looks fine (line reading is not the most performing way to do it and buffer size is probably on the small side but that should not be a deal breaker). Maybe you can add timestamp printing so you can see where the delay happens. (Especially is it while print_certs which means it is the connection/handshake or is the print taking so long.
BTW: when measuring you also should not print to console, that can be very slow on embedded devices (and in general)
As soon as you provide us the error details we can help you with that, I don’t think there are specific compile instructions available for arm.
Gruss
Bernd

Re: apache httpclient
Posted by Somshekar C Kadam <so...@gmail.com>.
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

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). Do you count startup Time? How did you Test Java if it does not compile?
Is the only reason you look into HTTPClient the delay you see with URLConnection? Do you have a sample program for that which shows the slowness?
Gruss
Bernd

Hi Bernd,
Thanks for the quick reply.
Excuse me on the replyall part, my bad.
when I use curl same https connection quickly returns within 2 seconds,
ofcourse different cipher is used.
Also I am not able to get sample apache httpclient compiled on Ubuntu Linux

help.

Hello,
Certainly you can use the Apache HTTPClient to replace URLConnection, you don’t need to do anything special on ARM other than having Java Runtime installed.
If you have a slow http download changes are high this is caused by slow CPU, missing random numbers, slow network or server. All those conditions might affect URLConnection or HTTPClient, so there is no guarantee that switching to Apache HTTPClient will improve things.
BTW your CC List is insane, why would you want to bother people like that?

Dont find any steps to get it working, is there any link how to use it on
ubuntu machine httpclient working, please point.

httpsclient instaed of openjdk httpsurlconnection.

Posted by Somshekar C Kadam <so...@gmail.com>.
Hi All,
I am a newbie to Java.
We are going to try Apache httpclient as an alternative for openjdk
httpsurl connection class.
We see that using openjdk 8 and above we s eee that when using httpsurl
conenction we see a delay of 10 to 20 seconds to get content of the url. We
use Armv7, Linux. We wanted first to begin with to get normal httpclient
working on Ubuntu Linux machine.
Dont find any steps to get it working, is there any link how to use it on
ubuntu machine httpclient working, please point.
Also you like to know hopefully this approach is correct to try Apachr
httpsclient instaed of openjdk httpsurlconnection.
please advice
