@musicman I don't think there was a #TomEE in 2004. I hadn't even heard of #Glassfish yet. I used regular #Tomcat (with #Apache and #IIS) at school, and even looked into a #Java based web host ... but the work schedule and commuting (and then traveling and #hotel_INET) just made it not doable.

The ports are open and the username and password are correct. Does anybody know why I am not able to connect to a MySQL database looking at this #java stacktrace? #wildfly

I was trying to remember the process for writing #Java #servlets.

so, my #postgres application seems to work in #wildfly. I guess I need to write a #java application to test it? I've never used Wildfly before so...yeah.

Wildfly is a #Java application server and container, similar to #Jetty and #Tomcat

@musicman It has been a loooong time since I've messed around with #Java (I'd say 13-14 years), but if the CLASSPATH was set correctly, I never had to unjar jarfiles. I never had the situation where a required file was missing from the jar, so you may be in unknown territory.
-
@musicman That sounds like a good idea.
Being that this _is_ #Java, also take a good look at the command line and environment variables needed for starting it. In the olden days, variables like $JAVA_PATH and $CLASSPATH had to be defined before the "java -jar somejarfile.jar" command ... some variables were small enough to define on the command line with "-Dsomevar=somevalue".
-
It seems unlikely to me that something like #Cassandra would be missing such a file. Do I need to build Cassie from source to get this or something? I haven't been able to find anything to suggest this is a common issue. Is it lying and the javaagent is actually the issue? #java [root@localhost tmp]# java -javaagent:./jmx_prometheus_javaagent-0.12.0.jar=8080:jmx-prom.yaml -jar …

I had one interesting experience I want to note: I took a couple of #Java courses at the community college level. During my master’s degree program, I was in a Java course completed online. I was in a group of six students, most of whom had not taken Java previously. Four students and I struggled with the assignment, with attempt after attempt that failed to meet objectives. …

@musicman if they’re using #Java, they’re probably going for cross-platform. It is less true than before, but even now, #Windows administrators prefer GUI tools, even when CLI / TUI tools are more functional and faster.

To flesh that out a bit, but my current list is this:
#mongodb
#mysql
#httpd
#postgres
#kafka
#cassandra
#tomcat
#jboss / #wildfly
#eclipse
#java (enough to diagnose applications...honestly, with the others on the list that are built in java, I probably don't really need to do anything else with this one)

As I am learning more and more, I think one reason #Java is so popular is because it is very developer-centric. Like, everything in Java is a jar, war, or ear. I feel like #PHP is more administrator-centric with the dlls and ini files. Not that I am any sort of expert in either. Maybe it's just the type of Java learning that I am doing, and of course there is JVM stuff that is…

It's pretty demoralizing to never get any responses from anyone but @lnxw48a1, but I am nothing if not persistent. I realize I could interact more and gain more followers and I could post more. Maybe I'll give Mastodon a shot a see if I get more interaction there. I don't think I've joined an instance but maybe I have. Anyway... My team is looking! Requirements (I mean, that's …

A couple of things I've heard !Smalltalk people say killed their market: 1. Smalltalk's image-based system didn't mesh well with OS filesystems; 2. #Smalltalk vendor turmoil and their high pricing. (I wasn't even aware of the language's existence until the late #1990s. I took numerous programming courses over the years, but I never heard ST mentioned until another student ment…
