I downloaded the Smack example code to send GCM to Android devices from a server.
When I run it on my dev machine I get a Smack debugging window.
On my server I get this:
Exception in thread "Thread-6" java.lang.IllegalArgumentException: Can't initialize the configured debugger!

How do I disable the Smack debug window?
After I go
myConfig = new ConnectionConfiguration(SERVER, PORT);
I have to go
myConfig.setDebuggerEnabled(false);

Your JRE: 11.0.10+0-b96-7249189 amd64 (Oracle Corporation)
C:\Program Files\Android\Android Studio\jre
The log shows that there is a problem with establishing loopback connection . please check your firewall / network connections (e.g. VPN etc).
I have a problem with the newest version of macOS (BigSur 11.0.1) and the library PC/SC; before BigSur the program the uses the library worked fine but after the update isn't working anymore. I am using the java version 1.8.0_271
In the code, I use the method TerminalFactory.getDefaultType() to get the default type of Terminal Factory. Before the update I was receiving "PC/SC" but after the update I am receiving None.
If I want force to connect to an instance with this line
TerminalFactory factory = TerminalFactory.getInstance("PC/SC", null);
It will return the following error:

I found that Big Sur eliminates the library PC/SC and it is no possible to install it.
I don´t know if there is someone with the same error or someone that has already fix it.
Thanks for the help.
Because of the changes in macOS Big Sur, Java PC/SC implementation no longer works correctly:
https://bugs.openjdk.java.net/browse/JDK-8255877
The workaround is to set the system property:
sun.security.smartcardio.library=/System/Library/Frameworks/PCSC.framework/Versions/Current/PCSC
before trying to use TerminalFactory.
Recently I have downloaded JDK 11.0.2 & Tomcat 9.0.16 and set the environment variables, but whenever I am starting the tomcat it is showing the following exception in the console and http://localhost:8080/ is not accessible.
Please help.

I also tried with different connector ports but did not worked, but when i tried same thing with same configuration in another machine it worked without exception and localhost was accessible. Is there any problem with my machine.
This mistake means that your port is busy.
Stop Tomcat
Change the port number
Restart your app

I was able to narrow down my problem to the following case:
I'm creating Kubernetes pod with two containers:
couchbase - initialized version with one bucket from offical Couchbase 3.1 image
my java app that tries to connect to Couchbase and use this bucket
My app's code is as follows (full content of main function):
CouchbaseEnvironment ce = DefaultCouchbaseEnvironment.builder()
.connectTimeout(10000)
.build();
CouchbaseCluster cluster = CouchbaseCluster.create(ce, "127.0.0.1");
Bucket bucket = cluster.openBucket("my_user", "some_pass");
JsonObject jo = JsonObject.empty();
jo.put("SomeName", "someValue");
bucket.upsert(JsonDocument.create("my_id", jo));
It fails on last command with timeout:

I don't know how to fix this or get to the root cause as timeout is very unlikely as the Couchbase is having only one, empty bucket.
PS when configured logs for Couchbase client I was able to see keep-alive entries working just fine.
I'm using official Couchbase java client in version 2.1.0. Also tried 2.1.6 and 2.2.5 but no luck.
The problem was created by me - the bucket I have created didn't had password set and I tried to connect to it with password...
I wanted to delete whole answer but I thought that it might be helpful in case someone else have similar problem
I am running Titan 0.5.0 with Cassandra 2.0.8.
When I first ran my Java client with a local Titan-Cassandra I could connect to it. Now that I deployed the Titan-Cassandra remotely on a Debian Wheezy with dedicated user I have a "Connection refused exception" (see stack below). I can connect to Titan via Rexter on the remote server via http://my-domain.com:8182 and I can see my vertices and edges.
What is the changes to do on a local configuration (Java client and Titan on same machine) to make Titan with Cassandra and Elasticsearch run on a remote machine accessed by my Java client?
Java client code
private final URL titanConfiguration =TitanRepository.class.getResource("/conf/titan-cassandra.properties");
public TitanGraph load() {
return TitanFactory.open(titanConfiguration.getPath());
}
Working configuration with local Titan-Cassandra:
Java configuration titan-cassandra.properties
storage.backend=cassandrathrift
storage.hostname=127.0.0.1
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.5
index.search.backend=elasticsearch
index.search.hostname=127.0.0.1
index.search.client-only=true
schema.default=none
No change in the Titan conf directory
NOT working java configuration with Titan-Cassandra on remote server

If Rexster runs on the same (remote) box and can connect, but you can't connect from your local machine, then it's most likely a Cassandra configuration issue. In cassandra.yaml set rpc_address to 0.0.0.0 (currently you've probably set it to 127.0.0.1), restart Cassandra and try to connect again.
