i've created this webpage using jsf,prettyfaces and hibernate
i looked around and most people says that this error is because of cache
most of them found this error after login,logout and try to login back
but i found this error when i log in,and when i try to navigate to any other page,any link that i clicked will produce this error
what makes it harder is that this error doesnt occur everytime
sometimes when i try restart the server,login back,everythin work just fine
but sometimes when this error occur again, i tried restart the server and try login back.the same error still occur

JSF keeps a (configurable) number of views in the session. You will get this ViewExpiredException if you do a post to a view that cannot be restored anymore, ie. not present anymore in the list of views for that session.
There can be multiple reasons for this. Two possible scenario's I can think of right now are:
Session invalidated/expired
Multiple (> configured number of sessions in view) views being created after the one that should be restored
To my understanding this is caused by the combination of several things:
A JSF-form containing an internal id for a field has been generated.
The JSF-page has been changed, or the whole application redeployed, causing the internal ids to change.
The JSF-form with the old internal id is submitted (a login page?) and the old internal id cannot be found in the new ids for the JSF-page.
You must have the page refreshed in the browser (getting the new id's) before attempting to submit again.

I am using Crawler controller to crawl all pages of a medium website. It randomly crawls 2-3 pages and then it causes a lock on the IndexWriter
Directory dir = FSDirectory.open(new File(index));
IndexWriterConfig conf = new IndexWriterConfig(org.apache.lucene.util.Version.LUCENE_41,new StandardAnalyzer(org.apache.lucene.util.Version.LUCENE_41));
writer = new IndexWriter(dir, conf); // line which throws lock exception.

Why am I getting this exception? Any help.
UPDATE: 17/08/2014 :
When I run the Indexer first time, it completes successfully with the below exception thrown. If I run the search on this, I get my results successfully. However if I run the Indexer again, it throws the lock exception mentioned above. It also shows that my controller class is called twice.

Quoting the Javadocs -
"Opening an IndexWriter creates a lock file for the directory in use. Trying to open another IndexWriter on the same directory will lead to a LockObtainFailedException. The LockObtainFailedException is also thrown if an IndexReader on the same directory is used to delete documents from the index."
"IndexWriter instances are completely thread safe, meaning multiple threads can call any of its methods, concurrently. If your application requires external synchronization, you should not synchronize on the IndexWriter instance as this may cause deadlock; use your own (non-Lucene) objects instead."
https://lucene.apache.org/core/4_1_0/core/org/apache/lucene/index/IndexWriter.html
Are you creating new instances of IndexWriter for each page that you are crawling?
I'm trying to Download a pdf from a MySQL-DB ( I get it as a Blob, and up to that point everything works just fine. But when I try to get the ServletOutputstream to send it to the client the programm crashes.
AFAIK the exception is thrown when the method has been called before or the getwriter-method has. But I don't use the getwriter-method in my code at all and the other getOutPutStream-methods in the programm are not reached (I commented them out to make sure).
(The whole thing happens in a JSP if that matters for any reason)
Heres my code snippet and the Exception:
Code
Blob pdf = null;
if(request.getParameter("reportId") != null){
pdf = testszenario.getReportErgebnisPdf(Integer.parseInt(request.getParameter("reportId")), request.getParameter("erzeugung"));
}
byte[] buf = new byte[(int)pdf.length()];
InputStream inputStream = pdf.getBinaryStream();
inputStream.read(buf);
inputStream.close();
response.setContentType("application/pdf");
response.setHeader("Content-disposition","attachment; filename=test.pdf");
ServletOutputStream sos = response.getOutputStream();
// response.getOutputStream().write(buf);

Please check if your response is committed. If you try to do something on a committed response then IllegalStateException may arise. Response will be committed, if page buffer size is exceeded.
It might indeed matter that you're doing this in a JSP. Keep in mind that the JSP is part of the output rendering phase of a web application request, so the container might have obtained the writer object already. Try moving your code into a servlet instead. It'll give you more control over the writer/streams.

But it works fine when I deploy it on my localhost. I tried to find the solutions for this but not getting. So Help me out...
I'm not familiar with this guy "Ebean ORM", but the error track is pretty generic and seems has nothing really to do with "Ebean ORM" itself. Based on my past exp, it is more like a classloader issue. You said it was running fine locally and then? where is it broken? when you have such issues like "NoClassDefFoundError", always check what classloader is being used. And also it is worth to check whether your broken environment has multiple versions of the class/jar as well as if the server has its embedded version of this class/jar.

And the cursor path is valid, the cursor is visible on app but in log I always find this error. Other problem is that on IE8 the performance is highly impacted only for two custom added cursors. I'm wondering if I must add .cur extension on mime types?
If anyone have e suggestion please let me know, thank you.
So my question would be why are you using java for this you can easily modify your cursor with css, which would be the easiest and best practice as a user can easily disable it if they want.

Yes, your authentication is not working because Twitter made some recent changes
regarding how it lets 3rd party code authenticate.

In other words, Basic authentication has been turned off for the API.

As Allain mentions, oAuth is the way to go.
The code you posted is different than what I've seen in the past for connecting. I think (though I'm not sure) that oAuth is the preferred way of authenticating now.
Here's a blog that details using oAuth to connect.
I was having that trouble, finally the solution was to put a valid Callback url in my twitter API at (https://dev.twitter.com/), I used google+ url, saved changes (it could take a minutes before the changes are made, refresh the page to be sure) and it worked.
