I've just entered the SIT phase with a Spring Boot app server deployed on Tomcat 7 using MySQL in AWS
Tomcat7 is running on a Ubuntu EC2 instance with MySQL on the standard DB server
Initially id set up my database connection in my hibernate.cfg.xml file
however i was getting problems with stale connections
the pattern was always the same after server startup
1) for around 24hours no issues
2) 24 - 48 hours - DB connections would start failing, first at a rate of about 1 in ten then to about 2 in 3 after 48 hours
lots of reading around suggested that
a) I should really configure my datasources via JNDI
b) I should not use auto connect in the DB URL as thats been deprecated
c) using the testOnBorrow property should ensure my application server doesn't attempt to use a connection that will fail
So I went ahead and set that up
heres how i configured by JDNI in my server.xml
<Resource name="jdbc/FootyPicksData"
auth="Container"
type="javax.sql.DataSource"
username="[my db user]"
password="[my DB passoword]"
url="jdbc:mysql://[my DB url]
driverClassName="com.mysql.jdbc.Driver"
maxActive="15"
maxIdle="3"
maxWait="5000"
removeAbandoned="false"
removeAbandonedTimeout="20"
logAbandoned="true"
validationQuery="select 1"
minEvictableIdleTimeMillis="3600000"
timeBetweenEvictionRunsMillis="1800000"
numTestsPerEvictionRun="10"
testWhileIdle="true"
testOnBorrow="true"
testOnReturn="false"
/>
So i set this up and off i went
after about 24 hours same problems appeared
well , i thought this hasn't worked lets check the logs
Now I'm getting a different error , but in exactly the same ratios (10% ish after 24 hours , 70% ish after 48 hours

Well off I google again and lots of the answers suggest this is a fundamental issue with how i'm managing my DB sessions via Hibernate
at this point its worth adding that when setting up Hibernate there was 2 main design patterns, one in which you explicitly open and close connections yourself, another where you begin and commit transactions, you grab a session using getSession(), which as far as I can understand will attempt to grab an existing session , if none exists open one
so for example heres a snippet of how all of my data layer services work
public boolean saveOrUpdateLeagueMember(LeagueMember leagueMember) {
Session session = HibernateUtility.getSession();
session.beginTransaction();
try {
session.saveOrUpdate(leagueMember);
session.getTransaction().commit();
return true;
} catch (Exception e) {
System.out.println(e);
logger.error(e);
session.getTransaction().commit();
return false;
}
}
then some Spring magic somewhere will close the session
What is going on? is the issue in the application code or in the pooling set up ?
if its the code why its fine for 24 hours then slowly starts to fail?
Is there just something fundamentally wrong with how I've set this up?
That feels most likely as this is pretty standard stuff I'm trying to do here...

I have a problem with Shiro session management. I am facing this error below :

I have implemented custom security manager and session configurations in shiro with xml based.
I have also implemented URL rewrite filter using filter chain
Can't able to redirect to Login page, after Logout
SecurityUtils.getSubject().logout();
return new ModelAndView("redirect:/login");
It has to redirect after logout to login page
So I am kind-a stuck in a strange situation, explained briefly, I have a web form that when filled fills a PDF template using PDFbox and saves it in given location. Now the App works fine in my eclipse environment but when I run it on a test tomcat server it fails with the following :
ERROR c.j.h.controller.HomeController - I=0 fields=FullName{type: PDTextField value: null}
ERROR c.j.h.controller.HomeController - I=0 fields=FullName{type: PDTextField value: COSString{fsdf}}

Now If you look at the top of the errors you can see a few ERROR messages that I have created to help identify where it goes wrong.
Now my specific code looks like :
InputStream template = HomeController.class.getResourceAsStream("template");
PDDocument pdfDocument = PDDocument.load(template);
PDDocumentCatalog pdfCatalog = pdfDocument.getDocumentCatalog();
PDAcroForm acroForm = pdfCatalog.getAcroForm();
PDPageTree pages = pdfCatalog.getPages();
ArrayList<String> myObjectList = new ArrayList<String>();
List<PDField> fields = acroForm.getFields();
for(int i = 0; i< firstAidList.size(); i++) {
log.error("I="+ i + " " + "fields=" + fields.get(i));
fields.get(i).setValue(myObjectList.get(i));
log.error("I="+ i + " " + "fields=" + fields.get(i));
}
// Few more stuff done then I close
pdfDocument.close();
template.close();
Basically myObjectList is the data I get from the web form, the fields is the fields I get from my pdf template and in the for loop I just set them up - but if you look at the code and the first error messages the problem occurs when trying to set the 2nd value.
As it works in my eclipse but not the tomcat server(separate from the eclipse one) one of my thoughts is towards some permissions on the tomcat server but have no idea how to "prove" it.
Seems the solution was to restart the tomcat server.
Related to problems with BreakIterator after java updates on the server.
We were using version 3.1 of datanucleus for JDO with java 6 and recently we have upgraded it to v5 of datanucleus along with java 8. After upgrading we are facing issue in existing code when try to use count as size method.
Query tcQuery = pm.newQuery(TrialData.class);
tcQuery.addExtension("datanucleus.query.resultSizeMethod", "count");
#SuppressWarnings("unchecked")
Collection<TrialData> totalTrials = (Collection<TrialData>) tcQuery.execute();
int size = totalTrials.size();
It is throwing NucleusUserException exception.
datanucleus.query.resultSizeMethod of "COUNT" is only valid for use with JDOQL or JPQL currently

I am having some strange issue, my spring boot app works just fine on localhost, but, when deploying it on the server, sometimes it loads data just fine, but I get 500 error occasionally, it's on the pages where I display data from mysql using angularJS.
Has anyone experienced a similar issue?
Below is my application.properties file:
spring.jpa.hibernate.ddl-auto=update
# Replace with your connection string
spring.datasource.url=jdbc:mysql://localhost:3306/myapp
spring.datasource.connectionProperties=useUnicode=true;characterEncoding=utf-8;
# Replace with your credentials
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.test-while-idle=true
spring.datasource.test-on-borrow=true
spring.datasource.connection-test-query=SELECT 1
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
And here is the log ( sry because it's long ):

Hope it helps someone :D
I am using the spring framework to connect. It is giving me the following exception nearly 2 out of 10 times. The problem is intermittent. I have checked my internet connection and code thoroughly. My hunch is that there is some issue with postgre instance on AWS but I am not able to pinpoint what exactly the problem is. Please help.
