1) I used the below code to the SDE 10.3 direct connection from java
String instance = "1234";//sde port
String server="host";
if (conn == null) {
try {
conn = new SeConnection(server, instance, database, userName, password);
System.out.println("Connection Successful");
}
I got the below error
[java.lang.UnsatisfiedLinkError: no sdejavautil in java.library.path] with root cause
I have to install the ArcSDE 10.3 on my local machine so that I can able to avoid this issue.
