Solr 4.1 Core Initialization Failure [duplicate]

This question already has answers here:
Solr RequestHandler init failure
(2 answers)
Closed 7 years ago.
I have updated my version of Solr from 3.5 to 4.1
I have removed the old war file from my apache tomcat (7) webapps, and deployed the new war file that has been provided in the apache-solr package.
I got the following error upon trying to access solr from the web browser!
I have one core only(dbTrial)
Solr opens but this error appears.
SolrCore Initialization Failures
dbTrial: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: RequestHandler init failure
There are no SolrCores running.
Using the Solr Admin UI currently requires at least one SolrCore.
Unable to load environment info from null/admin/system?wt=json.
This interface requires that you activate the admin request handlers in all SolrCores by adding the following configuration to your solrconfig.xml:
Can you help me out? I have tried adding the request handler as specified, but it didn't work.
It seems that the new versions of solr need a new format for solrconfig file. can you assist please! thank you!
the log is the following:

Check the Solr log for a better error of what the issue is when Solr is starting up - you'll probably have a better error message there than the one you can see in the Admin interface (which is the error triggered when the interface attempts to access the Solr core). The reason why the core or requestHandler isn't loading will be in the log file, and not in the message produced by the UI. Remember that logging also changed at 4.3, if you've updated to 4.10 (I see that you wrote 4.1, but if you're planning on going the whole way (or meant 4.10) - the logging might have to be configured as well).
You'll also want to consider the "going from 3 to 4" document, that details the changed to the configuration files (as solrconfig.xml changed a bit).
Update
The log shows that it's complaining about loading "solr.DisMaxRequestHandler". This has been deprecated for quite some time and has been removed - just use the standard request handler from the example solrconfig.xml instead.
<requestHandler name="standard" class="solr.SearchHandler" default="true">
<lst name="defaults">
<str name="echoParams">explicit</str>
</lst>
</requestHandler>

index.jsp not found (cannot be loaded)

i am trying to create a dynamic web app in Eclipse (Tomcat v7). The problem is that when i run my webapp index.jsp cannot be accessed. I can Access every other .jsp, but the index.jsp not.The next problem of course is ´that index.jsp cannot be loaded at the start of the app. I get the following message:

I have tried everything (the last option was to create a index.html and redirect it to the index.jsp but it didn't work). I have also tried to copy index.jsp in every folder of the app but it also didn't work.
Here is my web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>Test_WebApp_1</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
I have also searched on Google, and there where some cases where the index.jsp was not loading, but the solutions didn't help me.
Does anybode has some idea ? Could this be something with Apache ? I have tried to run Version 6.0 but i could not start it because it didn't support some of the modules used in my app.
So, i am happy for any Information
Kinde regards
Semir

i have tried something else. I have exported my app as a war and deployed it on Apache. When i run my app right from Apache it works fine, and the index.jsp is being loaded. So i assume it is something in eclipse
edit : i solved it by installing the jdk develpment kit and Setting the JAVA_HOME Variable
thanks für the answers

Do you work under a sensitive case OS?
Because your error is: org/apache/jsp/index_jsp (wrong name: org/apache/jsp/Index_jsp
with an uppercase on Index_jsp.
Check your UR, check your file name...

Java Web Start can't find jar with formatted version filename

I have simple-as-can-be Web Start application sitting on a file server. The directory consists of the following:
foo__V1.1.jar
runfoo.jnlp
The contents of runfoo.jnlp is as follows:
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" href="http://myserver.com/runfoo.jnlp" codebase="http://myserver.com">
<information>
<title>Foo</title>
</information>
<security>
<all-permissions/>
</security>
<resources>
<j2se version="1.7.0_06+" href="http://java.sun.com/products/autodl/j2se" />
<jar href="foo.jar" main="true" version="1.0+"/>
<property name="jnlp.versionEnabled" value="true"/>
</resources>
<application-desc name="Foo" main-class="com.myserver.foo.Foo" width="640" height="480" />
<update check="always" policy="always" />
</jnlp>
The issue is that Web Start is attempting to access a file at http://myserver.com/runfoo.jnlp?version-id=1.0%2B, and not finding it.
I assume there's some extra step required to have Web Start automatically grab the latest jar version in this simple instance, but after a lot of Googling all I've found is the same steps over and over:
rename file to <file_name>__V<versionnumber>.jar
Add the versionEnabled property to the jnlp
enjoy versioned goodness
The jnlp file runs absolutely fine when I specify an explicit file name, but always fails when I've tried to implement versioning.
I'm sure I'm missing something vital but I haven't been able to find it anywhere. I'm guessing that although my set-up is simple, it's not simple-as-can-be-and-also-work.
Any help will be much appreciated :)
The explicit exception is:
com.sun.deploy.net.FailedDownloadException: Unable to load resource: (http://myserver.com/foo.jar?version-id=1.0%2B, 1.0+)
I've also tried removing the + from the version specification and the same error occurs (apart from a missing plus of course). Writting foo__V1.1.jar in the jnlp file works but of course defeats the whole point of this.

The versioned file names are a convention used by the JNLP download servlet to know what to serve when the client asks for lib.jar?version=something. You need the download servlet on the server side (or you need to duplicate its behaviour in mod_rewrite rules or similar), just the plain files with versions names is not enough.

When Run As at Server,Eclipse - Tomcat - java.lang.NoClassDefFoundError: javax/servlet/ServletConfig

I'm fighting the whole day with this:
I have DynamicWebProject. It worked fine. But at some point I desided to clean extra jar wich didn't used in project. After my cleaning, I've got a bunch of errors. So I rollback all my changes (I mean I retuned all jars back). But Also I played with Build Path of project, of Eclipse, of Debug config. Unfortunately I didn't remember this changes (with Path stuff). And when I run as at server, tomcat shows me this:

I'm real tied with this endless fight. What I'm doing wrong? What Eclipse and Tomcat tries to tell me?
Done.
So. How I restore functionality.
First of all, my project was backup in SVN repository.
Next I create new Workspace in Eclipse. new workspace in different folder. And Checkout project from SVN.
After that, at step - run at server, I caught errors, and added one by one missed libraries(jars). And whoa-la, it works!
So how I thought, problem resides in configuration of eclipce and project, also in Run/Debug Configuration. How to find errors in configuration, I don't know :( but I'll try at old workspace.

You are missing servlet-api.jar in your class path. Check it
UPDATED
1) Right click on project
2) Got to java build path
3) Click on add library in right hand side.
4) Choose server run time.
5) Click next and select your tom cat server.
6) Click on finish.
Then try again

Go to the Java Build Path, go to Libraries, click on Add Library, choose Server Runtime, click Next, choose your webserver and click Finish. Clean and deploy to see if it works.

I've added a Tomcat 7.0.12 in Servers, and I added the app. in 'Configured' in the 'Add or Remove...' window. I've also tried with Tomcat 6.0.x.
I think I have a problem in some of the *xml files, but don't know which one to check or paste here first.
And to note that I can make a war file with Maven and when I deploy it and start it on a Tomcat server the app works. But from Eclipse I cannot start it.

You need to delete the tmp0 folder, bounce Eclipse and retry. This usually happens when Eclipse does not exit gracefully while the embedded server is running. You should stop the server before exiting Eclipse, that should help.
