I'm having trouble with tomcat 8 at my server - tomcat8

I'm having a problem with my Application. At my local machine it works fine, but when I upload it to the server (runs Tomcat 8 with JDK 8) it doesn't work. And there's nothing in the logs.
I need some help, because I don't know what's happening.

You should provide more details, at least regarding how your deployment is made. Do you copy a .war built with maven in the /webapps directory ? What command line do you use to start your server ? Is the .war getting correctly exploded ? Or do you simply copy classes in a directory under /webapps ?
I'll provide more info (and hopefully a solution) once the post is clarified :)

Is there a way to clear IBM MobileFirst Platform server Cache?

I'm working on an IBM MobileFirst Platform 7.1 project where there are many name value pairs in the worklight.properties file.
Say for example,
HOST_NAME = www.google.com
I access these variables form the MobileFirst adapter.
var hostName = WL.Server.configuration["HOST_NAME"]
There will be cases where I'll have to change the HOST_NAME in the worklight.properties to a different value. But sometimes, even after the value is changed in the worklight.properties file, they are not getting updated in the adapter.
Every time when I change the values I do the following,
Clean the project
Restart the server
Deploy the adapter again
Nothing seemed to change the value.
I suspect, the MobileFirst server caches the values and reuses the old values without updating the new ones. I say this because, I tried deleting the values in the worklight.properties file, and even tried deleting the file itself. Still the adapter was using the old value.
I tried deleting the MobileFirstServerConfig Folder in my workspace. Even that didn't work.
It would be great if someone could help me clear the cache or find a work around to this issue. Thanks in advance.
I kind of followed the above method but initially it didn't work.
But later I tried to follow these steps in this exact order and it seemed to work.
Stop Worklight Server.
Remove your project from Mobile First Development Server.
Go to the "bin" directory and remove your project war.
Clean and Build the entire workspace.
Start the server
Deploy the adapters
Run your app.
The worklight.properties file is embedded into the project runtime WAR file. So, if you change anything in worklight.properties, you must rebuild the WAR file and redeploy it. Based on your description, it sounds like you're only building the adapter (and not the app). At minimum, I would suggest to remove the runtime WAR file from the project "bin" directory (just to ensure that it gets rebuilt) and build all app environments. That should build / redeploy the WAR file and restart the server, and then what you're doing should work.
Here are the steps to follow:
1. If worklight server is up and running, stop it or restart your system.
2. Clear bin folder.
3. Do Clean Project and Build for enviournment.
4. Open Mobile first Console(Start server)
5. Deploy All adapters
6. Run your app.
If wlq or wl error is comming we can give an alert message 'test' in our main file where we have all the javascript files.

Intellij and Apache Tomcat not updating

I have a project going on for a couple of months now using a Spring MVC framework. For developing I am using an Apache Tomcat 8.0.17 with an exploded war file. Everything worked well since yesterday. Now when I change my Java Files the changes are no longer visible. I can even throw runtime exceptions and stuff like that (I always restart the tomcat server). The only way to "update" my code is to rebuild the whole project (Build --> Rebuild Project) which is quite time consuming and very annoying.
I did not change anything in the configuration nor updated Intellij IDEA or the Tomcat Server.
I could fix this by manually deleting all the files in the following folder:
%userdir%/.IntelliJIdea14/system/tomcat
After a full rebuild the updateing process works perfectly again.
Use this is VM Options:
-Dcatalina.home=%tomcat_folder% -Dwtp.deploy=%tomcat_folder%/webapps -Dcatalina.base=%tomcat_folder%

How to Fix No MBean found for Worklight project?

I have a problem when deploying my Worklight project on the server . It shows the following Error Message :
FWLSE3041E: No MBean found for Worklight project 'MyProject'. Possibly the Worklight runtime web application for Worklight project 'MyProject' is not running. If it is running, use JConsole to inspect the available MBeans.
and when I tried to preview my application it showed this message :
SRVE0777E: Exception thrown by application class 'com.worklight.core.auth.impl.AuthenticationFilter.verifyServletInitialized:420'
I had the same issue using Worklight 6.2 CLI, but recreating the project did not work.
One issue that I had was that worklight did not build a .war-file properly, so I copied the .war-file from a backup.
Edit: This happens regularly in our project now, and we have no idea why. We fix it by invoking any procedure, which makes it work until you restart the server. Worklight must be building something when invoking a procedure that it does not do when building.
I Solved The problem by creating a new Worklight Project and copied all my files , it works just fine :) I used Worklight 6.1 instead of 6.2
I solved this by fixing a recently created security test in
server/conf/authenticationConfig.xml
The problem was I mispelled the Realm name I previously defined.
I solved this problem by deleting the application from the worklight server and rebuild it.
Delete WorklightServerConfig folder in workspace and rebuild your application.
I was able to fix this in MobileFirst 7.0 (Fka Worklight) by opening the Servers view, Window -> Show View -> Servers. Then expanding the MobileFirst Development Server and right click on the project in question, chose delete.
Once you do that go back to the applications' directory in the "apps" directory and right click -> Run As -> Run On MobileFirst Development Server
This should rebuild and deploy the project on the server.
I solved the problem by using ibm jdk not open jdk. My solution is to make sure the env parameters are correct
export JAVA_HOME = $your_ibm_jdk
export PATH + $your_ibm_jdk/bin:$PATH
run java -version to make sure the setting work

problems deploying openMRS.war to glassfish v.2

I'm trying to deploy openMRS v.1.9.2 to a local VM running CentOS & Glassfish 2 for work. Unfortunately, I could not get it to work. Normally, I just download the standalone found at source forge. I just double-click the jar, and I'm good to go.
I normally just SSH into the the VM, so I first tried doing everything through a terminal. Here are the steps I took:
Using wget, retrieve the .zip
Create a dir (I just called it /openmrs), cd into the new directory, and then expand the .zip.
cd into the directory.
At this point, there are two options to start openMRS.
Run the bash script: ./run-on-linux.sh
Run the .JAR: java -jar [insert_jar_name].jar -commandline
When I run the .JAR, I get a stack trace.
When I try to run the bash script, I get another error.
Anyways, I thought I found a potential solution in an openMRS JIRA ticket, but it seems aimed at Glassfish 3, and not Glassfish 2 (which is what I need to use).
I then tried deploying the .WAR via the Glassfish admin UI. I thought it would work, but after going through the steps of selecting a language, whether or not to use demo data, etc. I received this.
Does anyone have experience deploying openMRS to Glassfish 2.1.1? Unfortunately Glassfish 3 doesn't seem to be a realistic option. I would really appreciate any help here. Thanks.
Although it doesn't solve my problem of not being able to successfully deploy openMRS to an instance of Glassfish v.2, I did manage to get myself further by just installing MySQL on the VM. Our work machines are all set up for postgres, so I think should have guessed earlier that not having a MySQL server installation was the problem.
Here is a tutorial I used to install MySQL

Weblogic could not find class in WEB-INF->classes directory

I have a very weird problem.That my web project deployed to the Weblogic 10.0,Monday afternoon,and every thing works fine.But the next day morning, i checked the application, it reported could not find class that i write myself below the WEB-INF->classes directory.
I also use ant to build my project,But the same war file works on Weblogic10.3 and Tomcat5.5.So it may be the Weblogic 10.0's issue.But i also test it in another environment which have Weblogic 10.0, and it could not work too.
So could anyone can help with it ? I work a whole day yesterday to figure this out.
Even change the JDK to recompile the code and war file.
Please Help or leave something that helps, Thanks!
i finally figure the issue out. That cause the jdk version matters.
The annotation "#override" in jdk1.5 was not supported as in jdk1.6.
And the Weblogic10.0 still use the jdk1.5, so it matters.
