susi server failed to start in cygwin

[charany1]

I followed steps mentioned in README of susi_server , however my server is not starting .

I changed LoklakServer to SusiServer in build.xml like this :

<manifest>
<attribute name="Class-Path" value="${jar.classpath}" />
<attribute name="Main-Class" value="org.loklak.SusiServer" />
</manifest>

Terminal Outputs :

susi server failed to start. See data/loklag.log for details. Here are the last logs:
Error: Could not find or load main class org.loklak.SusiServer
Error: Could not find or load main class org.loklak.SusiServer

I'm not able to figure why it's not able to find main class ?

Since , I'm seeing that my classes directory has a SusiServer.class :

 /c/cygwin64/home/danchara/git/susi_server/classes/org/loklak (development)
$ ls
api/ data/ EmailHandler.class graphics/ objects/ susi/ SusiInstallation.class SusiServer.class
Caretaker.class 'EmailHandler$1.class' geo/ http/ server/ 'SusiInstallation$1.class' 'SusiServer$1.class' tools/

Name of the main class is SusiServer, made some fixes here: 2693cc9

I always start Susi just with bin/start.sh

[charany1]

@Orbiter , thanks for the fixes , I pulled your latest commit , however problem is still there . Could it be due to the reason that I'm using a Windows machine ?

In bin/start,sh , I've changed ':' to ';' as class path separator , however , it doesn't work.

[Orbiter]

it looks like that ps -o does not work on cygwin.

[Orbiter]

I dont't have a cygwin development environment because I don't have a windows computer. I would like to hand over this issue to someone with a windows/cygwin development environment

[sudheesh001]

@charany1 Can you try this
START java -Xmx4G -Xms1G -server -XX:+AggressiveOpts -XX:NewSize=512M -cp "classes;lib/*" org.loklak.SusiServer

It should open up a new command line instance running java.

[sourabhtk37]

Should I take this up?

[sudheesh001]

@sourabhtk37 I am not sure if there's anything in this that needs to be taken up, I am waiting for @charany1 to reply so that we can see what to do next. For me in a cygwin environment it works when I use the command above.

[charany1]

@sudheesh001 , I tried your command , it said START command not found , however when I omit START , it opens up a new CMD type window , which closes automatically in a second .

That new CMD window shows some ERROR message , before I can figure out what that is , window closes .

Will check back next Thursday , till then Happy Deepawali :)

[sudheesh001]

@charany1 Run the start command from the Command prompt cmd.exe instead of cygwin and can you tell me then what happens ?

[sudheesh001]

Or there's another option, if the build seems to work correctly, do this, execute the jar

ant jar
java -jar dist/loklak.jar

That should run it, loklak.jar because this file hasn't been edited. https://github.com/fossasia/susi_server/blob/development/build.xml#L131

[Orbiter]

I merged #22 please try again

[charany1]

@Orbiter , I pulled code after your merge #22 .

@sudheesh001

1. On doing

START java -Xmx4G -Xms1G -server -XX:+AggressiveOpts -XX:NewSize=512M -cp "classes;lib/*" org.loklak.SusiServer
from a CMD , a new CMD window opens up with message

` ERROR StatusLogger No log4j2 configuration file found . Using default Configuration : logging only errors to console .

-----plus some other stacktrace which before I can infer , window closes ---------`

1. On running

`ant jar

java -jar dist/susiserver.jar
`

[charany1]

Okay , so above error happened because I was on developent branch which indeed doesn't have susi_cognition_boilerplate.json.example , when I switched to master , and used

`ant jar

java -jar dist/susiserver.jar`

it worked , so I've server running at

http://127.0.0.1:4000/ .

Thanks @Orbiter , @sudheesh001 .

I'm closing this for now .
