    @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.

      Servlets are Java classes that conform to the Java Servlet API, which allows a Java class to respond to requests. In this tutorial, we will cover below topics to get overall understanding of java servlet technology.

    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.

    @clacke "Sounds like Oracle had been eyeing MySQL for far longer than I realized. Would they have even bought Sun if it weren't for MySQL?

    Is that even why Sun bought MySQL?"

    I'm sure that had something to do with why #MySQL became available for Sun to buy.

    First came the #Sleepycat purchase (followed by removal of the #BDB engine), then the #Innobase ( #InnoDB engine ) purchase, then #Sun purchased MySQL, then #IBM rejected Sun's attempt to get purchased, then Oracle purchased #Sun (along with its parts and products ... #Java, #Solaris, MySQL, and so on).

    By the way, whenever I need a MySQL compatible database, I select #MariaDB, to avoid #Oracle.

    Sort of off-topic: Do you remember when MySQL had a distribution deal for an open source version of SAPDB named MaxDB? It didn't seem to last long (a year or two?). I'm sure sales were much lower than SAP expected.

    @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 /usr/share/cassandra/apache-cassandra-3.11.6.jar -Djava.util.logging.config.file=./program.log

    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. The day before the assignment was due, the other group member handed us a completely working program, apparently forked off one of our earliest non-working versions.

    It turned out the instructor could see our group interactions (chats, forums) and marked him down for failure to participate. So he got the rest of us a passing grade on the assignment, but because his only interaction was the toss the finished program into our forum, he received a failing grade on the project.

    This was so long ago that we used MSN Messenger as our unofficial (out of the campus’s view) communication medium. I received an inquiry about my grade on the assignment. I shared it, expecting that every group member would have received the same grade, only to find that D received a lower grade.

    He tried to make a stink about it, but it is hard to argue with the interaction record.

    @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.

    #tomcat

    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 admin-like, but even that seems to be configurable in the code itself.

    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 what HR calls them, but not really...):
    Expert level in a number of open source packages.
    Broad and deep familiarity with multiple projects to include #Java and #J2EE, #JBoss, #ActiveMQ, #Drools, #HornetQ, #Hibernate, #Spring, #Linux (focus primary on #CentOS or #Ubuntu), #Apache #HTTPD, Apache #Tomcat, #MySQL, #PostgreSql, #Opensource project and community participation and Production/24x7 experience.
    Database administration; #postgresql/ #mysql/ #mariadb experience very desirable
    Expertise in #Cassandra, #Kafka, and/or #cloudnative applications is a plus.

    Minimum of five years of software development and design or systems administration or level 3-4 technical support experience.
    Technical knowledge, skills and expertise in complex infrastructure, web-based software and enterprise software
    Understanding of software best practices; #SDLC, #SCM and #Agile development principles.

    2. #Smalltalk vendor turmoil and their high pricing.
