B4J Question [SERVER] SSL Connection

T201016 · Aug 31, 2020

Hi,
When using an SSL connection, I get an error when compiling:

The Keystore key is correctly formed according to the tutorial.
I changed the rdc link to start with https: //

I have a well-configured server,
then this could be because I am trying to use a self-signed certificate?

Browser shows error message:
A secure connection could not be established. An error occurred while connecting to server '127.0.0.1:17178'.
SSL received a record that exceeded the maximum length allowed.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG

The page being opened cannot be displayed because the authenticity of the received data could not be verified.

thank you so much for help.

java.lang.RuntimeException: java.net.BindException: Address already in use: bind

This means that another instance of the server is already running (or a different app has opened the same port which is less likely).
Open task manager and kill all the java instances.

Hello Erel
Thanks a lot for the helpful hint! Of course, I will check how many of these instances have multiplied ...
I wish you a good day

I corrected the previous problem according to your suggestion,
but it throws me another error regarding the keystore key.
I used version jre1.8.0_251 to create it, maybe this
must one look for fault in it?

1.Created the key using the method:

keytool -genkey -dname "CN=Unknown,O=Unknown,C=Unknown" -keystore mykeystore.keystore -keysize 1024 -alias b4a -validity 14000 -keypass vakoss -storepass vakoss
pause

rem keytool -certreq -keyalg RSA -file mykeystore.csr -keystore mykeystore.keystore
rem pause

2. zainicjowałem w kodzie B4J Souce code:

ssl.SetKeyStorePath(File.DirAssets, "mykeystore.keystore") 'path to keystore file
ssl.KeyStorePassword = "123456"
ssl.KeyManagerPassword = "123456"

Any other hints?

Java version is irrelevant.

All that I can say is that you should carefully follow the steps in the tutorial: https://www.b4x.com/android/forum/threads/server-ssl-connections.40130/

It will work.
