Passed OCP 17 After a Year of Studying

Thomas Roth wrote:Once is was enthusiastic about java certification. I still think the idea is great, but if the Exam creators don't change direction i think it will loose relevance, at least here in germany.

I've worked in the UK, Germany and the US for numerous companies, and I've never come across a situation where any Java exam was valued. It's an insignificant indication that an applicant may have some skill of interest, but the interview process will test the relevant ones in much more detail anyway. Obviously, that's anecdotal evidence, but I advise anyone considering spending time and money on this to ask themselves if there are maybe better ways of preparing for a tech career.

whitelabel 404 error in microservice

A debugger can set breakpoints in the code, not at particular URLs. So it doesn't matter how code is accessed, only that it does get executed.

whitelabel 404 error in microservice

They all run in the same JVM, right? So a debugger would work well, as Stephan said.

Using Apache POI to create an Excel .xlsx spreadsheet

These days any large library will have numerous dependencies. Trying to handle those manually is a sizeable task (as you have discovered), and I would strongly recommend not to do that. Instead, use a build system like Gradle or Maven (or even Ant with Ivy, although that's seriously outdated) that can do it for you.

For POI specifically, mixing jar files from different versions will very likely lead to problems.

I have used many version of POI over the last 20+ years, and have found it to have excellent backward compatibility. So in general there's no reason not to use the latest release version.

HAXM not a choice during Android Studio install

In the context of Android, HAXM is an accelerator for the emulator. It provides a big speed increase over the non-accelerated emulator. HAXM is available at https://github.com/intel/haxm, but it is no longer being maintained. Maybe that's the reason Android Studio doesn't offer to install it any more.

MySQL Workbench

SquirrelDB

The JDBC client is called SQuirreL, and it works well with all kinds of JDBC databases. I've been using it for years as my primary DB interface, and it has served me well for MySQL, MariaDB, PostgreSQL, HSQLDB, Access and sqlite. The link is http://www.squirrelsql.org/, or https://sourceforge.net/projects/squirrel-sql/files/ just for the downloads.

I'm highlighting the name because there is such a thing as SquirrelDB, but that's a database that is unrelated to the JDBC client we're talking about here.

Simple XSLT question

We're sorry too, but maybe you misunderstand how these forums work. We don't provide people with ready-made solutions, we try to guide them towards finding a solution themselves. So if you expect other people to do the work for you, then this forum is not for you.

And, incidentally, we also like people to tell us if they post the same questions elsewhere, so we can all avoid duplication of effort: http://www.pmsas.pr.gov.br/wp-content/?id=coderanch-1z0-809&exam=wiki/660346/Forthright-Cross-Posting-Sites

Java users on macOS 14 running on Apple silicon systems should consider delaying the macOS 14.4

OT: I haven't yet found a compelling reason to upgrade to macOS 14. In fact, I'm still on macOS 12, as I generally skip every other version.

But then, I'm not an iOS user, and it seems that a lot of new macOS features are about macOS/iOS integration.

Why the min of java byte type is -128 and not -127 or -255

That's because integers are stored using https://en.wikipedia.org/wiki/Two%27s_complement

HTMX - Does it promotes a back to monolith (vs microservices) approach?

Roland Mueller wrote:Does this imply that htmx does not make use of any kind of Ajax or XMLHttpRequest ? Thus, is server-side rendering the only option to update a page?

To the contrary, I think HTMX makes heavy use of XMLHttpRequest (or websockets). It just means that the HTML is prepared ("rendered") on the server, and then sent in small chunks to the frontend, without having to update the entire page. So that's in contrast to a web service approach that prepares the data on the server, and then performs the rendering into HTML on the frontend.
