NullPointerException in Login #20

Closed alrawi closed 6 years ago

alrawi commented 6 years ago

Hello, I am trying to get Kam1n0 installed on a Windows 10 64 bit machine with IDA 6.8. The plugin seems to install fine along with the server component. The issue I ran into is trying to login or create an account. In the Web UI I click on the Login link in the upper right, but I am not able to proceed. I checked the JS logs in the HTML page and it seems that there is NullPointerException in the server component.

Here is the message from the JS console:

{timestamp: 1528022469514, status: 500, error: "Internal Server Error",…}
error:"Internal Server Error"
exception:"java.lang.NullPointerException"
message:"No message available"
path:"/login"
status:500
timestamp:1528022469514

Here is the Java message from the Kam1n0 server console:

java.lang.NullPointerException: null

I figured it out, it was a path issue. I needed to set the right data path for the program to run.

LiamKarlMitchell commented 6 years ago

How can we set the right data path?

Edit never mind. Had to set it in properties, work bench and program wouldn't run as I needed to make it use right version of java even though I had installed 8.

Edited this into the top of the bat script.

set JAVA_HOME="C:\Program Files\Java\jre1.8.0_172"
set PATH=%JAVA_HOME%\bin;%PATH%

And modified a copy of the bat to run the work bench as well.

@alrawi I am facing the same problem as you some years ago. Please help me. How to set the right data path? Thank you

@LiamKarlMitchell please I need your help.

@Edemos1er I encountered the very similar issue: java.lang.NullPointerException: null. After a detail inspect I found that the problem occurs at the last line in Kam1n0 panel: at java.lang.Thread.run(Unknown Source) [na:1.8.0_301] (because I installed jre 8u301). I reinstalled to jre 8u172 and it solved my problem. And btw, you need to run with admin privilege otherwise have error.
