QUESTION
I made a very simple application in Spring Boot. I have used very few features offered by the framework and despite everything I have problems updating my application to the most recent versions of the framework. I also note that the support for Spring Security is disappointing because there is no dedicated community. As I wrote in the title, my needs are only 3:
- add a remember me button during login;
- use BCrypt to encrypt by password;
- use spring security on the most recent version of the framework and therefore 2.6.x and possibly also 3.0.
In the past I have opened a thread on this forum because the documentation claims that support for Spring Security is here on Stackoverflow but I have not found a solution to my problem.
I can't update my webapp to Spring Boot 2.6.0 (2.5.7 works but 2.6.0 doesn't)
It is disarming to learn that Spring Boot applications are not updatable and even more disarming that the Spring Security team is not present on Stackoverflow. My request is very simple, how can I extend WebSecurityConfigurerAdapter and how can I implement UserDetailsService to get what I need with 2.6.x? Also, I wouldn't mind replacing javax with jakarta and trying Spring Boot 3 on JDK 17 but if the support is non-existent, the code I find doesn't work and I have to read a 1000 page book every new version of the framework the advantage of using a framework is null. I am very disappointed, I hope that some Spring Security developer wishes to intervene. Below you will find the commented code (see points 1 and 2).
To make the application work and not have this problem:
I have to use this code:

QUESTION
I have been using apache.commons.CSVParser for a while without any issues. I know this sounds silly like the dog ate my homework but, the parser doesn’t yield any records suddenly for the past two days now. Records size shows up with a non zero value in the debugger but the list returned from CSVParser.getRecords() is zero. Elsewhere I had read the correct way to access the list is to call the size() method on the getRecords(), which I have done. To reemphasize, the code was working fine. I was using commons:commons-csv:jar:1.5 for a while, it stopped working and I tried upgrading to 1.9.0 and the behavior is still the same
...ANSWER
Answered 2022-Jan-25 at 19:26(Both: your variables and their method-name)
A parser (even of class CSVParser) is a parser.
The records are a collection of records, that can be obtained using parser.getRecords() - as a List or Iterable.
Actually, the method is more than an idempotent getter. So getRecords() should be renamed to nextRecords() to be semantically exact 😉️.
Note the docs emphasize the streaming character of getRecords():
The returned content starts at the current parse-position in the stream.
In conclusion, getRecords() advances the parse-position with each reading invocation. Once you read the records for logging as “Size:”+records.getRecords(), the position in CSV stream advances and may be at end-of-file (EOF) already.
When you want the size or count of records, use the header-names as approximation: parser.getHeaderNames().size().

I am creating a CSV file using CSVFormat in java, the problem i am facing in both header and values is whenever the string is long and there is a comma the api is inserting a \ before the comma always. As a result the header is not forming correctly and the values in the csv file is taking next cell for the . I am posting the code what i have done
...ANSWER
Answered 2021-Jul-06 at 16:22This happens because you are using QuoteMode.NONE which has the following Javadoc:
Never quotes fields. When the delimiter occurs in data, the printer prefixes it with the escape character. If the escape character is not set, format validation throws an exception.
You can use QuoteMode.MINIMAL to only quotes fields which contain special characters (e.g. the field delimiter, quote character or a character of the line separator string).
I suggest that you use CSVFormat.DEFAULT and then configure everything yourself if you cannot use one of the other formats. Check if the backslash (\) is really the right escape character for your use case. Normally it would be a double quote ("). Also, you probably want to remove all the double quotes from your header definition as they get added automatically (if necessary) based on your configuration.

I am trying to create an embedded jetty server with JNDI. But somehow before start up I get the below error after i do mvn jetty:run.
I see all steps are completed but before server starts I get this error
...ANSWER
Answered 2021-Jun-25 at 11:15The class you specified oracle.jdbc.driver.OracleDriver.
Does not implement the javax.sql.DataSource interface that is required for this org.eclipse.jetty.plus.jndi.Resource.
You have many class options, depending on your version of Oracle server installed, your version of oracle jdbc jar file, and if you have other requirements (like transactions, pooling, etc.).
Just pick the correct class for the line (that's what's wrong with your current setup)
QUESTION
I am in the process of converting a Java 11 project with JSP and JSF web sites from javax.* to jakarta.*. For this I ...
- updated Tomcat 9 to 10
- updated all dependencies to the latest versions (build.gradle dependencies see below)
- changed all imports (javax -> jakarta)
- updated config files (web.xml, beans.xml, context.xml, faces-config.xml see below)
But unfortunately Tomcat 10 won't start now (StackTrace see below). I only get it to start when I remove jakarta.faces from the dependencies, but then no JSF pages run anymore, only JSP. So this is not a solution.
Does anyone maybe have a good idea what is going wrong here?
Thanks!

QUESTION
I have a library project that I use to hold some setup for my other projects that has a lot of utility classed and also utility libraries included. So, I changed all my "implementation" calls in the library's build.gradle to "api" calls so I don't need to reimport the dependencies again and again. After building the library and moving the jar from my library folder to the lib folder inside my main project, I can access all the classes in my library, but the transitive dependencies are not available in my main project.
I also tried using implementation and transitive = true, but no luck.
I'm using AdoptOpenJDK 16 and Gradle 7.0 and I already tried to rebuild everything after cleaning the cache.
library's build.gradle
...ANSWER
Answered 2021-May-25 at 09:11Information about transitive dependencies isn't included in Your jar. When You publish libraries to a repository via Maven or Gradle, there are several files being published:
- obviously .jar file with all compiled code
- pom.xml file (it contains transitive dependencies definitions)
- some files with checksums
When You just copy Your library jar to lib directory, Your application has no information about it's dependencies. There are several solutions:
Publish Your library to Maven Repository (Sonatype Nexus or JFrog Artifactory are most popular products to set up self hosted repository, but You can also use
mavenLocal()) instead of copying jar tolib- I think it's the best solutionBuild library as fatJar (jar file with compiled code and all it's dependencies - Creating a Fat Jar in Gradle)
Copy all of Your library dependencies to
