Every now and then I get the following exception. I do not get it everytime, it happens like 5 out of 10 time I request some page. I have built site using JSF + Hibernate and is deployed on Apache Tomcat.

The message of the root exception is telling you the problem:
Caused by: java.io.EOFException: Can not read response from server. Expected to read 4 bytes, read 0 bytes before connection was unexpectedly lost.
The network connection between your server and the database server is unstable. So this is not a problem of your software.

Iv got 2 SOAP web services, BankaService and CentralnaBankaService. I am trying to call some CentralnaBankaService method from BankaService method. They are on different apache-tomee-plus-1.5.0 servers.
When i call BankaService from client like this:
BankaService service = new BankaService();
Banka banka = service.getBankaPort();
banka.mt100(new MT100()));
It is works fine.
Also when i call CentralnaBankaService like this:
CentralnaBankaService service = new CentralnaBankaService();
CentralnaBanka banka = service.getCentralnaBankaPort();
MT900 response = banka.mt102(new MT102());
It works fine too.
But when i try to call BankaService mt103 method from client wich implementation is:
public java.lang.String mt103(org.projekat.mt103.MT103 parameters) {
CentralnaBankaService service = new CentralnaBankaService();
CentralnaBanka banka = service.getCentralnaBankaPort();
MT900 response = banka.mt103(new MT103());
return response.toString();
}
I get this exception in tomee.

It already happened to me when my application was holding sessions then i had to reboot the MySQL service, after that, always got the same error.
Check if your database isn't rebooting or something like this (connection issues).
take a look at this:
Hibernate Communications Link Failure in Hibernate Based Java Servlet application powered by MySQL
and this: http://vatsalad.wordpress.com/2010/09/28/hibernate-communications-link-error-c3p0mysql-and-broken-pipe-error/

I'm using Solr 4.3 with tomcat7. When the number of concurrent writes and reads increase it is crash throwing this SocketException error. I do concurrent commits and searches through multiple clients. Any kind of help is appreciated. Here is the tomcat log(catalina.out) and solr.log
tomcat log(catalina.out):

This is more low level error. I found this question&answers in stackoverflow and the summary of the solutions is to verify if you are really closing all the sockets (it would be indirectly due the framework) and check if it doesn't have other exceptions swallowed (like it needs more memory).
The peer has closed the connection. For example, the browser tab has been closed, or has navigated away to another page. There is nothing you can or need to do about it at your end. You can't write any more response, so stop trying.

I could not connect to mysql from java web application because I have created mysql database on user space. I think I have to pass socket file path also from configuration to connect to database. Please help me on connecting to mysql database through socket from hibernate.

I able to login to mysql in following way
bin/mysql --socket=socket -u root -p
but I could not connect to mysql from java web application,

In plain english, this is the operating system telling you it can't create an additional TCP socket due to resource congestion. Most operating systems have a hard limit on how many connections can be open concurrently. It is possible you have hit that limit.
To avoid issues like that, database connections are usually pooled, i.e. rather than dispose of a no-longer needed connection, the connection is kept around, to be reused for future requests to the database. There are a lot of connection pooling libraries. Pooling capability is also provided by most application servers, if you obtain connections from a DataSource mapped in JNDI.
Another possible cause is that you are not closing all connections after you have used them.
Does your application use directly socket connections or databases? Maybe your application creates many connections and does not close them.
You may try to enter in cmd
netstat -a
and analyze what foreign addres occurs most times and do you know it - check is it database address or sth else familiar to you.
