I have startet multiple Identical Apps in Tomcat (They display different content but the code is the same). These Apps use Hibernate and ehcache.
The Problem is: A singel Application works as expected. but adding a second one will make everything crash with nullpointerexception.
The configuration is:
// Caching
cfg.setProperty("hibernate.cache.use_second_level_cache", "true");
cfg.setProperty("hibernate.cache.provider_class", "org.hibernate.cache.EhCacheProvider");
cfg.setProperty("hibernate.cache.region.factory_class", "org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory");
cfg.setProperty("net.sf.ehcache.configurationResourceName", "com/gfop/util/hibernate/ehcache.xml");
// Query Caching
cfg.setProperty("hibernate.cache.use_query_cache", "true");
cfg.setProperty("hibernate.c3p0.statementCacheNumDeferredCloseThreads", "1");
This is the Stacktrace:

Have you ever experienced anything like this? Do you know how to solve this?
You use SingletonEhCacheRegionFactory, you should use EhCacheRegionFactory. Now you have only singleton, so you are not able to get different instance, it is singlet :) Change it to EhCacheRegionFactory and it souhl be able to get another instance

I don't have a lot experience with Java but I was tasked to update a tomcat web service project so it uses JDK11 instead of JRE1.8. I embedded JDK11 without changing any dependencies, but now I got this error when sending request to the service:

We're still using Axis1 (v1.4), and to the best of my knowledge (and my research) it is supposed to be compatible with JDK11, so I guess I'm missing something obvious here, and I don't know what. How can I fix this error?
So, like i said on title. I have permissions over target file, but when running my app this exception is displayed

I tried to run a simple app, only to write on file and i had no problems. But when running app on server at tomcat8.0 i get that exception. I searched on web, but i only found answers relatively to file permissions (something that i already own it) or something related with security, that in this case i don't think that is the problem because the exception raised is about FileNotFound.
Thanks in advance! It's my first question, sorry for something you don't like (formatting, language, etc) ;)
I'am working on a JSP site with a servlet and a Tomcatserver.
At the moment I can't figure out the problem for this error:
javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/jdom2/input/SAXBuilder
I already googled for this problem and tried every possibility.
The jdome2 is included
and there is also no fault about the SAXBuild function in the code
Here is the stacktrace I get when I run the project
SCHWERWIEGEND: Servlet.service() for servlet [jsp] in context with path [/Quiz] threw exception [javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/jdom2/input/SAXBuilder] with root cause

I aleady tried to use jdom1.x.x instead of jdom2 but it didn't work
Hope someone could help me.
Simply move this jdom jar to WebContent/WEB-INF/lib/.
I am assuming that you are not using build tool like maven or gradle.
We are seeing this exception from a variety of sources. It's happening on a cache check from spring. In all cases, no annotation exists on the method (for caching). It happens intermittently, not readily reproducable. Seems embedded when it attempts to get the ClassUtils.getMostSpecificMethod:
return targetClass.getMethod(method.getName(), method.getParameterTypes());

As stated in SPR-12917 this is a bug in the JDK
We tracked it down to the NewRelic Agent. We resolved it by disabling Spring AOP instrumentation in the agent (via configuration - newrelic.yml).
Newrelic is working on a resolution to the issue.
SPR-12917 outlines this discussion.
I added to a project a Webservice. The webservice needs gets a string and passes it to a function of the project and shall return the answer string.
The string shall be saved the database. When I run the Project in the console all works fine but, but when I run the webservice on Tomcat I get following Error:

Here is the code in the project I used to connect to the database
public Connection con()
{
String host1 ="jdbc:oracle:thin:#VM-PROJ-852:1521:xe";
String username ="Steve";
String password = "sys";
Connection con = null;
try{
con = DriverManager.getConnection( host1, username, password );
return con;
}
catch (SQLException e)
{
e.printStackTrace();
}
finally
{
return con;
}
}
I dont know how and what to change. I hope you guys can help.
U didnt define driver type use this "
oracle.jdbc.driver.OracleDriver
" as driver
add this statement at beginning of ur code
Class.forName("oracle.jdbc.driver.OracleDriver");
First check whether you have the correct oracle driver is in the class path and then add the following code
static{
try {
Class.forName ("oracle.jdbc.OracleDriver");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
