I am using TomEE 7 and JSF 2.2.
I use ajax in a commandButton and it worked fine. But suddenly (not sure what exactly has changed in the application), it is not working, and the commandButton refreshes the page. Checking the JS console it says:
Uncaught ReferenceError: mojarra is not defined
at HTMLInputElement.onclick
So thanks to this post I discovered that the JSF script was not accessible. So it was loaded in the page:
<head id="j_idt3">
....
<script type="text/javascript" src="/myApp/javax.faces.resource/jsf.js.xhtml?ln=javax.faces&stage=Development"></script>
</head>
But if I try to load the script directly in the browser I get a 500 error, and the logs in TomEE say this a bunch of times:

So I am now a bit lost on what to try or which direction to go for further research of the problem. Any ideas?
UPDATE
After some testing I have seen that one of my new added dependencies (I am using Maven) seems the responsible for the error. How a dependency can interfere the JSF libraries I don't know. Any suggestion on how I can continue isolating the problem?
Finally, I think I got it. Solution at bnguyen82 answer in this question.
I had to add
<scope>provided</scope>
Inside the dependency in my pom.xml.

I'm trying to create a chatbot that makes get the request to spring-boot application and spring boot application makes an API call to Dialogflow V2. I'm trying to access the Dialogflow V2 API via gRPC. I have created a service account and export service account key file and added it into the spring-boot application.
When I try to send a request to dialogflow from spring-boot application I have the following error:

I have tried that on personal network it works perfectly but when i tried on company network getting above error.
What should I do to fix this error? Any suggestions are most welcome.
Thanks in advance!
Check the system time on the machine where it's not working. Possible causes are: incorrect timezone, incorrect time in containerized or virtualized environments (e.g. clock on a VM and its host might not be in sync), or simply incorrect time. Check this out Google Client Invalid JWT: Token must be a short-lived token
I had the same problem, and it was my company's VPN that make a mess.
I had this error and the clock on the GCP VM was off by a day. I ran chronyd -q 'server pool.ntp.org iburst' to correct the clock.
I'm working on a web project and standalone app project that use the same database (using hibernate). Both are based on Spring and use Services and Repositories. Since both projects often get to interact with the same entities, i used to have a copy of almost each Repository and Service in each project which was a mess to maintain. I decided to create a third project and put all the common code in it. I am then adding the resulting jar file as a local maven dependency but i'm getting errors compiling something that used to work perfectly fine when the code was "local". This was my old component scan annotation :
#ComponentScan(basePackages = "com.mdenis.mdhis_webclient")
The new classes (same code in different package in a jar file) are in a different package so I am now trying this :
#ComponentScan(basePackages = "com.mdenis.mdhis_common")
There are still local beans that I need to load from the old local package so i will eventually need to get the component scan to check 2 different packages but for now i'm just trying to get this to find my services and repositories in their new "external" location. I'm getting this exception when running the web app :

It's only complaining about UserService but i have about 30 services in this app and i'm pretty sure it's having issues finding all of them. Am i doing something wrong to make this work? The jar file is correctly loaded in Netbeans and the package structure is correct.
* EDIT *
This is the part of my POM.xml that loads the jar i compiled in my third project. It is correctly being added into the project and the hundreds of classes who depend on these classes have no errors :
<dependency>
<groupId>com.mdenis</groupId>
<artifactId>MDHIS_Common</artifactId>
<version>1.0-SNAPSHOT</version>
<scope>system</scope>
<systemPath>${project.basedir}/src/main/resources/MDHIS_Common.jar</systemPath>
</dependency>
Regards
What if you just change your component scan to
#ComponentScan(basePackages = "com.mdenis")
or
#ComponentScan({"com.mdenis.mdhis_webclient","com.mdenis.mdhis_common"})
Then both packages will be scanned.
I found the problem. the system scope for Maven assumes you will be providing the classes yourself. I installed my jar into my local Maven repository and removed the scope and systemPath attributes. Everything now compiles perfectly.

We want to use EHCache3 in our springboot microservice to cache binary objects (A PDF and some metadata) These objects are between 50K to about 12m. Using a simple test I can load the cache and see it working.
The problem occurs when a large PDF is cached. The following stacktrace is shown
2017-02-03 21:08:47.936 INFO 11 --- [http-nio-8080-exec-4] .e.c.i.r.LoggingRobustResilienceStrategy : Ehcache key 5dd12ae803ea06c4d37afe949090b934 recovered from

I suspect that the problems lies in the configuration I am using for the caching but I can't figure it out. I am using constrained values in the heap and disk store to test proper eviction when the cache is full. Normally I would expect new content to push out older content from the cache, and give me lowered performance. But right now I am getting out of memory exceptions that I cannot explain. Is there something else to understand about the tiering of ehcache?

Looking at the stacktrace and inside the Ehcache 3 code - approximately as you do not give the exact version - it seems the OOME happens during serialization of the value so that it can be stored on disk.
When you put a value in a multi tier cache in Ehcache 3, the value is always written to the lowest tier - disk in your case. However in order to do that the key and value must be serialized. By default, Ehcache 3 relies on Java serialization to do that job, thus requiring keys and values to implement Serializable which, given your setup works, is the case for PDFTO.
In detail, the way this works is that the object is serialized and then put in a ByteBuffer which is then written to disk via offheap memory. But that means we need to be able to allocate a large enough ByteBuffer in order to proceed.
So the problem is not with the heap tier, since objects living there were already allocated before being passed inside the cache, but with the transfer to the disk tier.
I recommend looking into your overal heap usage and understand why you are so constrained or maybe check the serialized size of your objects. There might be a surprise lurking there if they have too many outgoing references.
Accepting 4 entries onheap means that there can be 4 entries. Whatever the size. So if your heap is small and your objects large, you can indeed get and OOME.
Your solution is to give your heap store a maximum memory size (<heap unit="MB">256</heap>) instead of a number of entries.
That way, entries will be evicted when needed and before getting an OOME (assuming the maximum memory size is lower than what's left on your heap).
I'm using this example: https://github.com/foo4u/keycloak-spring-demo
I have keycloak.json file in my WEB-INF folder, but when I run my application, I get this exception:
java.lang.RuntimeException: Must set 'realm' in config

This code is just an example of integration between Spring boot and Keycloak.
Can you please tell me what am I doing wrong?
Thanks for your answer and time.
Even though that's a good and valid example, that dates from 2015. I believe it uses Keycloak 1.2.0 which is completely outdated. There are a set of examples with Spring here. Most of them up to date with the latest changes.
I suggest taking a look at these examples and read the docs as well.
If you are using keycloak adapter with spring boot 2 or spring boot 1.5, you have to mentioned below properties in application.properties or application.yaml file
keycloak.auth-server-url=http://localhost:8180/auth
keycloak.realm=abc
keycloak.resource=movie-app
keycloak.public-client=false
keycloak.principal-attribute=preferred_username
If it still gives the error, please post the error, i will share the code :)
