SpringBoot in IntelliJ. unable to find valid certification path to requested target - spring

IntelliJ Community Edition, Java8, Spring Boot 2.1.11
Trying to do a basic linkedIn course (Building Reactive apps with Spring Boot2 by Chris Anatalio)
I am unable to run the application. It uses an embedded Mongo DB.

Update:
I found that LinkedIn provides an 'end' code set for each lecture. I downloaded and imported it and it ran fine. I dont know what is different. Did a WinMerge but no obvious differences.

Been in the same situation, Root cause is that you are behind a proxy server which requires ssl certificate to communicate/download.
Resolution:
1. Try different network, this worked for me when I connected to a mobile hotspot.
2. import/create a ssl certificate or bypass ssl, am also still exploring this path.

When I run the example code of openai-java in my machine, SSLHandshakeException error happens

I tried to run the example of openai-java, but SSLHandshakeException error happens.
here is my code
java.lang.RuntimeException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at io.reactivex.internal.util.ExceptionHelper.wrapOrThrow(ExceptionHelper.java:45)

at io.reactivex.Single.blockingGet(Single.java:2585)
at com.theokanning.openai.OpenAiService.createCompletion(OpenAiService.java:116)
Also, I used postman to send post requests to https://api.openai.com/v1/completions with my secret-key, it gives "You exceeded your current quota, please check your plan and billing details"
I guess it may because of https Certificate, and I followed How to Resolve Error message "PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target", and put certificate of https://openai.com/ into my JDK. And It doesn't work. I wanna ask how to fix this problem

Trust a Certificate Authority in Java

I'm trying to consume some webservices in my Spring boot Applications, I got this error in swagger when I try to execute my request, I tried to search for the url of the webservices in a browser (https://ip:port) then I got a security error telling me that the certificate authority is not recognized "SEC_ERROR_UNKOWN_ISSUER".. I thought that the problem is coming from there.
I tried to export the certificate from the browser and to import it in my cacerts but it didn't work.. Could a problem in my code be the cause of this error?
{
"timestamp": "2021-11-16T08:11:16.189+00:00",
"status": 400,
"error": "Bad Request",
"message": "I/O error: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target",
"path": "***"
}
Okay, I might be late with the answer but I am anyways going to post it here because I am pretty sure someone will need it in the future.
After hours of searching for the answer I found the reason. I haven't imported self-signed root CA certificate into the java's cacerts keystore and therefore, I kept on getting the same exception.
Command to add root CA to the cacerts keystore from one of the stackoverflow answers.
keytool -import -alias mycert -keystore "<<your-JAVA_HOME-directory>>\jre\lib\security\cacerts" -file mycert.cer
However, it did not work for me and I had to point it to
keytool -import -alias mycert -keystore "<<your-JAVA_HOME-directory>>\lib\security\cacerts" -file mycert.cer to my jdk instead of jre folder.
Default password of the keystore is "changeit"

Does Java 8 Jsse provider support sha224withRSA Algorithm?

jdk1.8.0.91 works fine here, but the latest revision (111) gives below error:
*handling exception: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Algorithm constraints check failed: SHA224withRSA*
Clients accept the certificate when using jdk1.8.0.91, or jsse.jar of that distribution. But when I upgrade to the latest revision of Java, I see above error. So which one is the correct behaviour?
This is an update from Java on windows, see below bug link for details

Unable to Resolve PKIX Path Building Failed

I try to connect to https web service using below code.
adapter.xml:
<connectivity>
<connectionPolicy xsi:type="http:HTTPConnectionPolicyType">
<protocol>https</protocol>
<domain>somewhere.com</domain>
<port>443</port>
<connectionTimeoutInMilliseconds>30000</connectionTimeoutInMilliseconds>
<socketTimeoutInMilliseconds>30000</socketTimeoutInMilliseconds>
<maxConcurrentConnectionsPerNode>50</maxConcurrentConnectionsPerNode>
</connectionPolicy>
</connectivity>
impl.js:
function getTest() {
var input = {
method : 'GET',
returnedContentType : 'json',
path : "WS.svc"
};
return WL.Server.invokeHttp(input);
}
Unfortunately, this error appears when I try to call the adapter:
{
"errors": [
"Runtime: Http request failed: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
],
"info": [
],
"isSuccessful": false,
"warnings": [
]
}
I have added the public certificate of the WS (accessed from browser and get it from certificate details) into my Java folder in Program Files (C:\Program Files\Java\jdk_version\jre\lib\security), however the issue still persists.
Is there any advise?
The instructions you've followed are incorrect when using MobileFirst Platform.
Follow the steps described in this user documentation topic (for Worklight 6.2, but valid for MFPF 6.3 and above as well).
Do not export the certificate from a browser because this action adds browser metadata and other artifacts which shouldn't be there. Instead use a tool such as OpenSSL to get the certificate (described in the documentation)
The certificate should then be stored in the keystore of the application server and not in your Java's JVM.

gradlew.bat (and gradlew) SSLHandShakeException

I'm new to Gradle and was going through this Spring Tutorial found here:
http://spring.io/guides/gs/gradle/
I get to the part where it tells me to add this task:
task wrapper(type: Wrapper) {
gradleVersion = '2.3'
}
I run gradle wrapper which creates the gradlew and gradlew.bat files.
Trying to run both of this I get this exception:

I try to hit the webserver at https://services.gradle.org/distributions/gradle-2.3-bin.zip and I'm not getting any sort of error. I'm I missing some sort of config? Any help would be appreciated. Thanks!
if you could not fix anyway. and if you are inside firewall.
then.
you may can not download https.
should fix that Edit gradle-wrapper.properties file.
vi [project]/gradle/wrapper/gradle-wrapper.properties
#distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-bin.zip
distributionUrl=http\://services.gradle.org/distributions/gradle-2.8-bin.zip
change from https to http...
http://blog.cjred.net/gradlew-bat-and-gradlew-sslhandshakeexception/
After I modified, it says: Server returned HTTP response code: 403 for URL: http://services.gradle.org/distributions/gradle-6.0.1-all.zip
I experienced the same problem, however my symptoms were that my Ubuntu machine couldn't resolve any SSL hosts unless I specifically added them to Java's certificate authority (cacert) file.
I stumbled upon this Debian bug, and found a fairly straight-forward resolution: remove ca-certificates-java and install it again:
sudo dpkg --purge --force-depends ca-certificates-java
sudo apt-get install ca-certificates-java
I did a ./gradlew clean for good measure, and everything sprung to life again.
It seems, that the certificates for the gradle site were messed up. Doing a gradlew clean should fix this. See this thread on the Gradle forum: http://discuss.gradle.org/t/urgent-ssl-apache-configuration-for-services-gradle-org-is-bad/8808/4
Steps:
Run gradlew -Djavax.net.debug=all tasks
Go through the debug logs, and see if you find anything out of the ordinary.
In my case, seeing something like Zscaler did the trick, as i know i have Zscaler on(which by the way rewrites the TLS traffic blablabla), and it was trying to find the valid certification path to requested target, which obviously it couldn't find.
2 Options:
Exit Zscaler
If exiting Zscaler is not an option, go to your browser, export Zscaler Root Certificate
If you are using Brave browser, here are the steps:
Settings > Privacy and security > Manage device certificates > Trusted Root Certification Authorities > Find Zscaler Root CA > Export
and import it in the JVM truststore gradle is using, something like:
keytool -import -trustcacerts -alias Zscaler -file "Zscaler Root CA.cer" -keystore "%JAVA_HOME%"\jre\lib\security\cacerts
IMPORTANT: Do a gradlew clean before retrying any command.
In my case the problem was caused by an obsolete (7 years old) version of Java. Even gradlew clean did fail. After a Java update it worked fine.
In my case I was on a company network and behind a proxy, which as I understand it rewrites the SSL certificates, making the Java installation not trust any of them.
To solve it I had to create a gradle.properties file in my home directory under .gradle (~/.gradle/gradle.properties) and add the following line:
org.gradle.jvmargs=-DsystemProp.https.proxyHost=<myProxyHost> -DsystemProp.https.proxyPort=<myProxyPort> -DsystemProp.https.proxyUser=<myProxyUsername> -DsystemProp.https.proxyPassword=<myProxyPassword>
That solution was based on this SO answer: Gradle use certificate authentication for repository
This is because, Gradle tries to find the installed package in your local machine.
If you have the installed location:
D:\apps\gradle-3.3
Follow these steps in eclipse:
New Project
Gradle Project
Enter project Name
Local Installation Directory
Click Finish.
You are good to go.
Create this profile in user home:
$ vi ~/.yarnrc
# THIS IS AN AUTOGENERATED FILE. DO NOT EDIT THIS FILE DIRECTLY.
# yarn lockfile v1
strict-ssl false
