QUESTION
I'm trying to find a way to initialize MessageDigest with Guice. Currently I have this:
...ANSWER
Answered 2022-Mar-25 at 18:00Edit
I did not know MessageDigest is a single use class. You showed an injection of that class, which by definition cannot provide multiple instances. So the question is flawed.
You must fix the problem by binding a factory function that creates an MD rather than the MD itself. E.g. a Supplier:

Can you try to save the properties without the spaces.
Like this:
logging.file.name=application.logs
QUESTION
I am using guice parser to parse proto file. It is not able to resolve imports. Any suggestions experts in how to resolve imports public as well as imports within same project ?
Proto file
...ANSWER
Answered 2022-Feb-04 at 02:45Let's consider the 3.1.38 version of the io.protostuff:protostuff-parser library as the current version.
It is necessary to use the FileReaderFactory and FileReader interfaces to get the «Include directories» support.
The solution is inspired by: protostuff-compiler/ProtostuffCompiler.java at v3.1.38 · protostuff/protostuff-compiler.
Example programLet's assume the /some/directory/imports directory is used for the imports.
QUESTION
I am trying to call an OWL API java program through terminal and it crashes, while the exact same code is running ok when I run it in IntelliJ.
The exception that rises in my main code is this:
...ANSWER
Answered 2022-Jan-31 at 10:43As can be seen in the comments of the post, my problem is fixed, so I thought I'd collect a closing answer here to not leave the post pending.
The actual solution: As explained here nicely by @UninformedUser, the issue was that I had conflicting maven package versions in my dependencies. Bringing everything in sync with each other solved the issue.
Incidental solution: As I wrote in the comments above, specifically defining 3.3.0 for the maven-assembly-plugin happened to solve the issue. But this was only chance, as explained here by @Ignazio, just because the order of "assembling" things changed, overwriting the conflicting package.
Huge thanks to both for the help.

...ANSWER
Answered 2021-Dec-23 at 11:26Found that MYSQL upgraded to 5.7.36 from 5.7.32 version and due to this gerrit service was not starting and failing with above errors.
Solved by replacing existing mysql-connector-java-5.1.43.jar with recent mysql-connector-java-5.1.49.jar in gerrit.
QUESTION
Request more information on this interceptor annotation. Why is the interceptor annotation called @AroundInvoke and not @BeforeInvoke?
Can I for example invoke an access verification before an action API? What is the guarantee that the Access Verification is completed before the method is actually invoked? Is there something that the VM or the CDI implementation do that does not prevent the actual invocation but execute this interceptor in parallel?
If I were using the Google Guice AOP Method Interceptors, I am assured that the Access Verification failure will determine whether or not the method invocation BEGINS. How can I assure myself of a similar behavior from the jakarta CDI?
Have not been able to find this information in the spec
A related question can be found here. But the exact questions above remain unanswered.
...ANSWER
Answered 2021-Nov-09 at 17:51@AroundInvoke is called that because it can act both before and after the actually invoked method. Look at the documentation and its sample:
QUESTION
Lets say I have a generic class as follows:
...ANSWER
Answered 2021-Nov-05 at 13:26No, it is not possible to achieve this in a way you are trying to.
But you could pass Class/Type object to Base's constructor and use it to create needed type literal, e.g. (I use Set as key since you mentioned multibinder):
QUESTION
I'm currently working on writing some tests for a java EE project that uses guice for dependency injection. Dealing with the entity manager and it's datasource has been giving me no end of trouble. I have tried multiple different approaches and they all seem to have a fatal flaw somewhere. I can't seem to figure out how to work with InitialContext without it cross contaminating my tests.
My first attempt was to manually bind the datasource into the context in the guice provider method for my datasource. Something like:
...ANSWER
Answered 2021-Oct-26 at 15:51In the process of researching another idea for this problem, I finally found a partial solution here: Junit Testing JNDI InitialContext outside the application server
The key insight was being able to 'reset' the context between tests. Once I had that working, I was able to cleanup my context between tests. Doing that removed the need for mocking out the Context; I could use a real implementation and be confident about the state it was in at the start of each test.
The finished version of the test module ended up looking like this:
QUESTION
I am using browsermobproxy and getting lots of errors that I don't want to deal with.
Is there a way to get a site's HAR file without using browsermobproxy?
If anyone's interested, here's the error I get from server.log
ANSWER
Answered 2021-Sep-16 at 07:44I believe you are running your browsermob proxy under the latest version of JRE. Since version 16 there are some limitation introduced to the refelction mechanism that make the code that used to work in previous versions not working any more.
So the easiest solution would be downgrade your JRE. According to this thread, JRE 11 would work for you.
QUESTION
Guice newbie here, with a complicated scenario.
My company has a large number of constants of a given type (let's call them Thingy) that belong to different teams and are maintained in different parts of our application. However, we need to have a central registry that knows about all of them (let's call this the ThingyService). I am writing a base module that teams can either extend or install, with the purpose of allowing a team to register their Thingys, and giving them access to the ThingyService. This module takes as parameter a list of classes from which I can extract the Thingy constants, this part is working fine.
What I don't understand is how I can a) make each module know about each other module's list of Thingys and b) how I can create my ThingyService as a singleton that contains all of my Thingys. I have experimented with shared static state and with ThreadLocals, but I keep either breaking tests or breaking my main (play) application. In my naive understanding of Guice, I think I need a MultiBinder for the Thingys, but I don't see how I can share that between modules. Here's what I'd like to do:
ANSWER
Answered 2021-Sep-02 at 04:24It turns out I omitted one important detail, Thingy has a type parameter, it's actually Thingy, and that's the reason it didn't work before. By cheating and registering Thingy as raw type, and then also injecting it as raw type, I got it to work.
Here is a complete working example using JUnit 5 and AssertJ:

Vulnerabilities
No vulnerabilities reported
Install guice
You can use guice like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the guice component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
