I am pursuing hybris training. In my hybris 2011, cannot access backoffice. Hybris administration console is accessible. It says "404 page not found". How to solve this?
problem solved. It arises due to some errors in trainingcore>resources>localization>trainingcore-locales_en.properties, where I have added some label names. I deleted them, ant clean all and then started server again.
note: ERROR [localhost-startStop-12] [ContextLoader] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'backofficeWarmUpTypeFacadeCaches' defined in ServletContext resource [/WEB-INF/backoffice-web-spring.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException.
This error message was there in terminal when I was not able to access backoffice.
Using HAC. Go to Maintenance -> Cleanup-> TypeSystem, and click "Clear all orphaned types".
Using Ant. If you execute ant -p you will see a list of ant targets, and there look for the target "clearOrphanedTypes"
clearOrphanedTypes: Clears orphaned types after system update.
Syntax: ant clearOrphanedTypes [-DclearInstances=true/false -DclearDeployments=true/false].
Default value for clearInstances is true, default value for clearDeployments is true
I had a problem and dell premium support ran some kind of upgrade or re-install of windows 10 while keeping my files in tack.
The next day, I was working on my MVC project in VS and it loaded ok and debugging got my application to the login page, which means it had to successfully read the Entity Framework Context with LINQ type stuff, and all of a sudden my project started having these errors about reading Entity Framework Context, but only in one method.
Then things got worse, I first tried to close VS and reopen VS. But this time, it said my project had been unloaded. I tried the option to reload the project, but now I was getting errors about "the operation could not be completed. the system cannot find the path specified" and errors having to do with not being able to find the current file highlighted at the top of the VS editor.
After looking up the unload issues in forums, I saw a suggestion to call up my Mbsa.csproj and change to false and to True. Then my project loaded ok - but why did this change? it was always false in my previous backups.
Then , when trying to run my project with VS Debugging, I started getting connection messages like these:
1 - C:\MBSSys\Mbsa\Mbsa 2020\Mbsa.csproj : error : The Web Application Project Mbsa is configured to use IIS. The Web server 'http://localhost:51700/' could not be found.
2 -The connection to 'localhost' failed.

So I am wondering if anyone else has faced this particular issue,
or, if anyone can give me any appreciated advice here.
Thanks for your time and advice. If you need more clues, just ask.
The seems to happen after installing KB4568831.
https://superuser.com/questions/1575295/windows-updates-kb4568831-kb4562899-break-all-net-applications-hosted-in-iis
I could get rid of the 500.19 errors by manually re-installing some optional windows features that the update apparently removes (see below), but after I got auth-related errors instead. In the end I rolled back KB4568831 to resolve the issue for the time being. Hopefully this gets fixed soon.
Im getting this error running my project.

Anybody had a clue why this is happening?
Thanks for the help
This error could happened for many reasons (and since you don't upload more code its pretty difficult to help you).
First Possible Reason
You are getting this error "no suitable driver" because the resource referens isn't beed added to the web.xml deployment descriptor, so add the following code.
<resource-ref>
<description>Database for IFPWAFCAD application</description>
<res-ref-name>jdbc/IFPWAFCAD</res-ref-name>
<res-type>javax.sql.data source</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
Second possible Reason
This may be tricky but check that there is not 'blankspace' on your xml files
Third possible reason
If you are deploying the current app lets call them "testApp" to a Webserver, have in mind that you should copy the mysql connector to the lib directory of that web server
Hope this Help You
While creating an Incident. I am facing this issue. I have created some incidents and it working fine but sometime it shows this exception "Incorrect attribute value type Microsoft.Xrm.Sdk.OptionSetValue".
How to trace which OptionSetValue throws an error.
I'm going to assume that you're creating these via a C# sdk call. I believe turning on server side tracing would tell you. The other option is if you can debug it locally, catch the exception and manually attempt to update each optionset attribute, one at a time until you find the culprit.
I have a very strange problem which I can't figure out by myself. I have a JSF application that I'm developing and it's deployed on a Tomcat server at client site. It works just fine. However, after a few days, it starts to behave very weird, and I'm getting a lot of exceptions such as the following in the log:
SEVERE: Error Rendering View[/index.xhtml]
com.sun.facelets.tag.TagAttributeException: /menu.xhtml #21,53 test="${!empty bean.menuItems}" /menu.xhtml #21,53 test="${!empty bean.menuItems}": Error reading 'menuItems' on type com.blabla.bean.ApplicationBean
at com.sun.facelets.tag.TagAttribute.getObject(TagAttribute.java:235)
at com.sun.facelets.tag.TagAttribute.getBoolean(TagAttribute.java:79)
at com.sun.facelets.tag.jstl.core.IfHandler.apply(IfHandler.java:49)
at com.sun.facelets.tag.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:47)
.....
Please note that bean refers to an object of type com.blabla.bean.ApplicationBean which is an application-scoped bean. The above xhtml code is inside a c:if, that's why I use the $ notation. As mentioned, the application runs just fine for the first 2-3 days, it is only after a few days when these exceptions occur in the log, and they are only related to the only bean that's in application scope. Normally, when I get such exceptions I check if the getter for the 'menuItems' field is in the bean, but it is there and if it wasn't, the application would not work at all and not work fine for 2 days and then crash.
I also encounter exceptions related to the custom resource bundle that I have in my application:
Caused by: javax.faces.FacesException: Could not load resource bundle for name 'messages': Can't find bundle for base name com.blabla.messages.CustomResourceBundle, locale de
Again, the bundle was loaded during the first 2-3 days of the application life, but then this exception occurs all of a sudden.
Has anybody encountered a similar situation? Can anybody point me in the right direction as to where to look for the problem, since I'm completely out of ideas here.
Thank you in advance.
