Server Tomcat v7.0 Server at localhost was unable to start within 90 seconds

I am facing issue with tomcat I am not sure about the problem, I have spent almost a day and tried everything but issue is still there.
In the console section INFO : org.eclipse.jetty.util.log - Logging initialized #1399ms line is looks strange to me.
Screenshot:

INFO: Server startup in 2982 ms

I faced the same issue several times. I'm using eclipse with fedora 20. In my case, I found that it happens in two occasions.
1.trying to Start Server in Debug mode with too many break points
2.After a several number of restarts.
In first case i removed the all breakpoints and cleaned the server and working directory and then issued command to stop it manually and then restarted the server.
In the second case i did like this, removed the server from eclipse, restarted it, and added the server.
The above solved my issue.

Right click on the server and select "Clean", and then "Publish", if there is something wrong with the server the error will be more especific when you use these options.
In my case it was on the server.xml. First check the server.xml file and go to the the context tag, your project path should be correct, if not correct that.

You can find out that library is taking time while starting Tomcat.
Start the tomcat server in debug mode and see what the stacktraces show.
It might be a library which is populating spring application context, initializing the file storage, etc.
Check the stacktraces and I hope you can find the problem there.
Alternatively, just remove all the webapps and check if tomcat now starts on time.

hi i am trying to run JAX-RS Web Service project which contain sample hello world web service, but publishing it in the Tomcat Server 7.0 shows following errors.

Please anyone help me to find out what is problem ?

In case you are using Jersey 2, you can download Jersey JAX-RS 2.0 RI bundle from their site and add JARs from ALL subfolders (api, ext and lib) to the WEB-INF/lib folder of your project.In my case, adding guava-14.0.1.jar fixed that particular ClassNotFoundException, but started failing on another unresolved reference, so I just dropped everything in my lib folder and managed to start the server without any problems.

Well this is the root cause:
Caused by: java.lang.ClassNotFoundException: com.google.common.base.Function
... so it looks like you're probably missing a dependency jar file (Guava, by the looks of it) from the classpath of the relevant classloader. If you're following a "hello world" tutorial, double check any steps which specify where to put jar files.

It looks like you may missing some dependency Jar file in your project or in your container.
Jar file may be one of the below.
google-collections-***.jar
google-collect-snapshot-***.jar
google-collections-1.0-***.jar

Simply copy and save your project to other location and delete from the eclipse. later delete the Tomcat from eclipse and make sure all the entries of your project gets removed from the Tomcat directory(server.xml file) and from your deploy path: wtpwebapps (in mine case).
Once done with clean up and integrate Tomcat with eclipse again, and start the Tomcat.
Bingo!!! it works.

Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]

I've jared my latest classes up and included it in my WEB-INF/lib directory and since then I've been getting this error and cannot run my project.
I have tried adding the commons jar into my project also but I'm still getting this issue. If I revert my project back to the original jar I created before adding new classes it works no problem.
Here is the error I'm getting:

It looks like you added a dependency on a Paypal library but did not include that library in your project:
Caused by: java.lang.ClassNotFoundException: com.paypal.exception.SSLConfigurationException
I'm not sure which jar, but it is most likely paypal-core.jar. Try adding it under WEB-INF/lib.

I had met a similar problem, after i
add a scope property of servlet dependency in pom.xml
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
Then it was ok .
maybe that will help you.

Just go to the project Properties->Project Facets
Uncheck the dynamic module, click apply.
Maven->update the project.

In my maven project this error occurs, after i closed my projects and reopens them. The dependencys wasn´t build correctly at that time. So for me the solution was just to update the Maven Dependencies of the projects!

Tomcat7 from Eclipse Server Timeout

I'm running tomcat7 form Eclipse and have also ensured that both Eclipse and Tomcat are using jdk-1.7.0. The server says "timeout. Server took more than 45 seconds to boot".
The error started occuring when I changed the JDK for my project in eclipse but I changed it to the same JDK in the run configurations as well.
PS: When I boot tomcat7 from outside of eclipse via the terminal, it works fine but when I try booting it form inside of Eclipse, it throws the error.
The complete error is as follows

If migration to another JDK was the only change and project runs at standalone Tomcat, then problem is that your Eclipse/project JRE version is differs from the Tomcat JRE version.
It should be the same.
Edit (after question update):
Please look at this question. There are shouldn't be any redundant libraries in Tomcat classpath.
Also ensure that you didn't touch any servlet-specific libraries, which should be placed at Tomcat/lib and only there (not moved or copied).
Also all your 3rdparty libraries should be placed at /WEB-INF/lib of your webapp, not elsewhere.

Run query cypher on tomcat, error with Scala library

I'm tring to run a query with cypher in a web app(REST) with tomcat.
This code works correctly in a normal java application, but if I run it on the web app with tomcat it returns this error:
java.lang.NoClassDefFoundError: scala/ScalaObject
if I add a scala-library.jar into project when I deploy on tomcat it return an error "OutOfMemory". Searching on the web, I have increased my JAVA_OPTS from 512M to 2048M but nothing.
This is my code to execute my query:
ExecutionEngine engine = new ExecutionEngine( graphDb );
ExecutionResult result = engine.execute( query );
It looks like the ExecuteEngine makes use of Scala library and this library conflicts with tomcat.
Any suggestions?
EDIT:
(full stack OOME)

The noclassdeffound is due to the missing Scala library so adding it to web-inf/lib is correct. Adding a library to the classpath won't lead to out of memory errors though, so it seems to be related to your app.
What is the class ExecutionEngine? What's the stacktrace (although that won't necessarily help). Are you sure your webapp is doing the same as your java app which has no problems? How are you testing your webapp? Could it simply be that many concurrent threads (requests) cause the OOME, but one thread works fine (like the plain java app)?
