It looks like there is a recursive loop in my spring set up.
I've looked in the applicationContext.xml and springapp-servlet.xml files and don't see any repeats or circular dependencies. I'm not all that familiar with spring and don't really know where to start to debug this.
Is there a way I can find out what property is being resolved?
Here's my stack dump

that happens since you dont have the datasource property file in your classpath or the direct values in your xml definitions where you have defined datasource or session factory

I have been trying to make a small application which first scans a HTML for data and then uploads it to my Firestore. I'm now essentially done with it and when starting it from within IntelliJ IDEA it works just fine. However as soon as I export it in to an artifact it starts throwing the following exception when trying to download/upload from/to Firestore!
I should mention that I'm coding in Koltin/JVM as it is way easier. Since there is no Kotlin Firebase-Admin version I'm just using the Java one which shouldn't be a problem since Kotlin compiles down to Java. If I'm wrong about that please correct me!

I have been trying to fix this for days now and literally spend hours googeling and trying different things but nothing has worked for me so far!
I tried:
randomly adding a LoadBalancer since I wasn't able to find any viable docs
adding the loadbalancer to my META-INF/services
I also found something that seemed similar here (https://github.com/grpc/grpc-java/issues/5493) but it talks about a load of stuff I don't use and frankly don't understand
FYI: Weirdly my icon from my resource folder turns into a completely different one in the Jar. Don't ask me why. I couldn't find an answer to that as well, but it isn't such a big issue since I can just replace that in the jar.
Oh and also this is my first question so if I made any mistakes I'm sorry! I probably made some spelling errors as well which I apologize for.
Any help would be greatly appreciated!
Hey so after googling some more I found some an article listing code snipets from LoadBalancerRegistry (https://www.codota.com/code/java/classes/io.grpc.LoadBalancerRegistry) and I scrolled around in it and found this: PickFirstBalancerFactory.init()
So i decided to look for this Factory but couldn't find it, instead I found PickFirstLoadBalancerProvider(). Remembering from randomly going through the autocomplete that in order to register something to LoadBalancerRegistry one would need a Provider.
Long story short I set them both together and added the following to the init section of my class and it works fine now!
LoadBalancerRegistry.getDefaultRegistry().register(PickFirstLoadBalancerProvider())
Thought I should answer if anyone has the same issue!
FYI: The icon still changes to that weird one. I don't know why or how thats even possible but it works if I replace it in the .jar so I don't really care xD
I get this error message when trying to connect to our webservices.
Error 404: javax.servlet.UnavailableException: SRVE0201E: Servlet [...] not a servlet class.
However, the class mentioned inside the brackets is a servlet class:
#WebService(serviceName = "xxx", endpointInterface = "xxx")
What I read was that in Websphere the class loader should be configured to Parent last; this is what I did and then to get rid of all jar - files that use Servlet.jar - I think I did this, too, since the only files that I am using are these ones:

Maybe someone could give me a hint or knows that the problem can be?
Thank you very much!
If you're relying on the annotation you mentioned, that's going to create a web service, not a servlet. Unless of course the class the #WebService is defined in extends javax.servlet.Servlet. Did you mean #WebServlet instead? Posting the pertinent portion of your source would be helpful.
This is one possibility:
https://developer.ibm.com/answers/questions/171243/srve0201e-servlet-my-webservice-not-a-servlet-clas.html
This text in particular:
The issue was showing up at deploy time and had to do with the fact
that my web services was referencing classes in a shared library. The
deploy code doesn't have access to the shared library so it wasn't
able to resolve things and gave up.
After some mad refactoring it started working.

Your solver config file is being read successfully. The problem seems to be inside the <scoreDirectorFactory> element, where you specify score DRL. Please make sure that you use the <scoreDrl> element and not <scoreDrlFile>. <scoreDrlFile> is supposed to contain a local file system path whereas <scoreDrl> is used to load a classpath resource (which is the case when the DRL file is located inside a JAR). It should look similar to:
<scoreDirectorFactory>
<scoreDrl>org/myproj/core/solver/myRules.drl</scoreDrl>
</scoreDirectorFactory>
I try to use jetty's ConcatServlet to concatenate javascript generated from my own servlet and javascript generated by wro4j WroFilter. It seems concatenation doesn't work, regardless the javadoc of ConcatServlet that states that it can be used to concat generated content.
I think the issue is that the wro4j content is generated by a filter an not a servlet as 'concatenating' a single source generated by my servlet works fine, while 'concatenating' the single wro4j generated resource doesn't work but I get the exception below. It complaints about a missing file, although the request /wro/script.js is served fine if requested normally. Any suggestions?

Can anyone tell me whats wrong?
Thank you
The compiler's already telling you what's wrong - it doesn't know what you mean by Database. Is that mean to be a property of the page, or is it the name of a type with a static Open method? It's not clear from the code itself, and obviously the compiler can't find the name either.
Work out what name you mean, then work out why the compiler can't see it, then fix that. If you need more help on any of these steps, you'll need to provide more information.
(As an aside, I completely agree with dbaseman: putting database calls in your view is a bad idea.)
If you're opening a database in your Razor view, that is completely the wrong approach. Your logic should go in the Controller, not the View. Consider creating a "view model" class that contains all the data needed for your view, and populate that class from the Controller.
Probably the reason this piece of code isn't working is that you will need to specify the full namespace of Database. I'm not sure what that class is, though; if it's in a separate DLL, you'll have more problems. Again, though, you should circumvent this problem by putting your database logic in the controller.
