User Management Ticket

[Georges_Bou_Ghantous]

Hi.

My implementation is correct (tested). However, when I run the application, the user-management fails on register. I ran all the tests in UserTest.java. The tests were successful.

I am wondering if this is a known issue

[kanikasingla]

Which JDK version are you using? I have seen this issue getting resolved with JDK 8.0 version.

[Georges_Bou_Ghantous]

Hi.

I am using JDK8.

Which is preferred for this course?

Cheers

George

@Georges_Bou_Ghantous

Which is preferred for this course?

JDK 8 only. Hmm… Can you share the github link or code in zip format by any chance?

Kanika

[Georges_Bou_Ghantous]

I will setup my code on GitHub soon. I havn’t Synch.

The course M220J

Java SDK8

Keep the ticket open please, I will work on it a bit then share my findings with you.

Cheers

Georges

Hi again.

I updated to JDK 15,

UserTest.Java runs fine.

However I still get same error when validating. Below is some of the error log:

Servlet.service() for servlet [dispatcherServlet] in context with path threw exception [Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter] with root cause

Please look at the following post:

Ticket:User Management: invalid response to register

Alternatively, I found that altering the dependency from <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt</artifactId> <version>0.9.1</version> </dependency> to <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt-api</artifactId> <version>0.10.7</version> </dependency> <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jj…

[Georges_Bou_Ghantous]

Hi again.

The solution peers talked about in the ticket was not helpful in my case:

I figured out another way.

JDK: Java 15

I kept:

io.jsonwebtoken

jjwt

0.9.1

And I added:

javax.xml.bind

jaxb-api

2.3.1

Now my code perfectly works

[Xiyuan_Feng]

Thanks Georges_Bou_Ghantous.

I got the exact same issue, it is solved by adding jaxb-api dependency even I’m still using JDK 1.8
