Java.lang.ClassNotFoundException

Я новичок в базе данных и не могу найти способ справиться с этой ошибкой. Я пытаюсь установить соединение между моим файлом jsp и сервером sql с помощью eclipse. Я скопировал свой драйвер ms sql в WEB-INF / lib и настроил «Путь сборки», чтобы он указывал на этот драйвер, но выдает ошибку. В чем моя ошибка и как ее исправить?

Вот сообщение об ошибке:

Я решил это. Что я сделал:

Поменял драйвер с 6.4 на 4.0
Синтаксис URL изменен на «jdbc: sqlserver: // localhost; databaseName = demo; IntegratedSecurity = true;»
Изменено «ВЫБРАТЬ имя, идентификатор, адрес ИЗ демонстрации» на «ВЫБРАТЬ имя, идентификатор, адрес ОТ людей», где люди — это имя моей таблицы.
Скопировал sqljdbc_auth.dll в Windows / system32

После этого сообщения об ошибках исчезли.

Попробуйте добавить Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); в Actor()

public Actor(){ try { Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); connection = DriverManager.getConnection(URL, username, password); selectActors = connection.prepareStatement("SELECT name, id, address FROM demo"); } catch(SQLException e){ e.printStackTrace(); }
}

2 ответа

Скорее всего, request.getParameter("contact"); вернет ноль, и вы попытаетесь преобразовать его в целое число. Попробуй это:

String contactStr = request.getParameter("contact");
if (contactStr != null) { int contact = Integer.parseInt();
}

Возвращенной трассировки стека должно было быть достаточно для устранения этой проблемы.

Как видите, можно отметить следующее:

Exception java.lang.NumberFormatException: null

Это фактически означает, что преобразование в число не удалось из-за значения null. Единственное место, где это возможно, из предоставленного вами кода:

int contact=Integer.parseInt(request.getParameter("contact"));

Поэтому вам следует сделать следующее:

Убедитесь, что request.getParameter("contact") возвращает ненулевое значение.
Убедитесь, что request.getParameter("contact") возвращает значение, которое может быть проанализировано в Integer, иначе процесс завершится с ошибкой.

Вот мой DeleteController (если я что-то напечатаю в doGet, то получаю от него результаты, а не пустую страницу)

@WebServlet("/delete")
public class MedicinesDeleteController extends HttpServlet { private static final long serialVersionUID = 1L; @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } @Override protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding("UTF-8"); int id = Integer.parseInt(request.getParameter("Id")); if(request.getUserPrincipal() != null) { MedicinesService query = new MedicinesService(); query.delete(id); response.sendRedirect(request.getContextPath() + "/"); } else { response.sendError(403); } }
}

Удалить функцию из MedicinesService ( я думаю, это моя проблема )

public void delete(int id) { DAOFactory factory = DAOFactory.getDAOFactory(); MedicinesDAO medicinesDao = factory.getMedicinesDAO(); Medicines medicines = new Medicines(); medicines.setId(id); medicinesDao.delete(medicines);
}

private final static String DELETE_MEDICINES = "DELETE FROM medicines WHERE id_medicines=:id_medicines;";
@Override
public void delete(Medicines medicines) { SqlParameterSource namedParameter = new MapSqlParameterSource("Id", medicines.getId()); template.update(DELETE_MEDICINES, namedParameter);

1 ответ

Первоначальная проблема заключалась в том, что это привело бы к вызову метода http get, а метод doGet () не имел кода для обработки того же

 <a data-hren="delete?drugid=${medicines.id}">Delete</a>

Вторая проблема заключалась в несоответствии имени параметра MapSqlParameterSource и заполнителя в запросе.

Эта ошибка является симптомом какой-либо другой проблемы, а не основной причиной, которую вы ищете.

Эта ошибка объясняет, почему пользователь не может быть перенаправлен на страницу с ошибкой. (Причина: сервер уже сбросил часть буфера ответа обратно клиенту — слишком поздно для переключения/перенаправления на страницу с ошибкой.)

Как указано в сообщении об ошибке, проверьте в других местах журналы Apache Tomcat 7 (или отлаживайте приложение другим способом), чтобы найти то, что бросает исключение.

Это обычная ошибка, и может быть обнаружена различная причина. В моем случае я открывал pdf файл из веб-службы, и для этого я выполнял операцию записи в файле с использованием буфера.
Так любезно измените ниже:

 File outfile = File.createTempFile("temp", ".pdf"); OutputStream os=new FileOutputStream(outfile); byte[] buffer = new byte[1024]; int length; /*copying the contents from input stream to * output stream using read and write methods */ while ((length = is.read(buffer)) > 0){ os.write(buffer, 0, length); }

 File outfile = File.createTempFile("temp", ".pdf"); IOUtils.copy(is, new FileOutputStream(outfile));

и после этого я выполнял операцию ниже:

 javax.ws.rs.core.Response.ResponseBuilder responseBuilder = javax.ws.rs.core.Response .ok(outfile, MediaType.APPLICATION_OCTET_STREAM); responseBuilder.header("content-type","application/pdf"); return responseBuilder.build();

и ошибка решена.
Ура!

Вы можете попробовать эту аннотацию, это поможет, поскольку она исправила мою проблему.

Это определенно поможет, если он не сможет вам помочь, а затем попробуйте изменить это согласно вашему требованию.

Надеюсь, это ваши потребности!

Я преодолел исключение, вы можете проверить структуру таблицы. Я выполняю SQL-запрос, созданный спящим в mysql.
Как исключено, было исключено исключение.

Я обнаружил, что идентификатор поля отсутствует в таблице. Добавьте идентификатор в таблицу, это нормально.
Надеюсь, что это будет полезно.

Попробуйте эту конфигурацию или переименуйте свой конфиг соответственно: я предпочитаю назвать сервлет как «диспетчер», а его контекстный файл — dispatcher-servlet.xml. Это сработало для меня.

<servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/appServlet/dispatcher-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup>
</servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>

попробуйте это: servlet-context.xml:

<?xml version="1.0" encoding="UTF-8"?>

Ошибки Servlet.init() в основном происходят из-за несоответствия версий файлов Jar вашего Spring MVC. Проверьте все свои библиотеки, щелкнув правой кнопкой мыши по проекту> properties> build path и удалите любую несогласованную версию jar.

Также удалите библиотеку jar из папки lib. Снова создайте проект и запустите его.

Дополнительно: Как пользователю передать права root

Just to confirm. You started with a brand new f20 freeipa instance, and then tried to clone a new freeipa instance (and it failed to restart). Is this something that is consistently repeatable?

According to the logs, it appears that the cloning operation is successful and that a new clone instance is created, but it then fails to restart because one of the self tests for the system certs fails.

Once the installation fails, you should still have a dogtag instance up on the clone. In this case, try to restart it manually.

Also, what is the output of :

certutil -L -d /var/lib/pki/pki-tomcat/alias

and please attach /etc/pki/pki-tomcat/ca/CS.cfg

Also, once the install fails — and if you are unable to start the service —
then it may make sense to see if the server cert really is the problem.

You can do this by removing the «sslserver» bit from ca.cert.list in /etc/pki/pki-tomcat/ca/CS.cfg
So, replace :
ca.cert.list=signing,ocsp_signing,sslserver,subsystem,audit_signing
with:
ca.cert.list=signing,ocsp_signing,subsystem,audit_signing

This will disable the cert verification self test on startup. Then try to start manually.

You can confirm if the CA is up by doing a :
pki cert-find

Just to confirm. You started with a brand new f20 freeipa instance, and then tried to clone a new freeipa instance (and it failed to restart). Is this something that is consistently repeatable?

No, I want to create replica of IPA, because VM was created from old template and we want to remove get rid of old VMs.

I was not able to create replica from fedora19->fedora20. So, I decided to upgrade IPA master to fedora 20 and create replica from fedora20->fedora20

Yes, it is consistently repeatable.

According to the logs, it appears that the cloning operation is successful and that a new clone instance is created, but it then fails to restart because one of the self tests for the system certs fails.
Once the installation fails, you should still have a dogtag instance up on the clone. In this case, try to restart it manually.

Yes, this works, but process of creating repoica is not finished and I don’t want to do others steps myself.

Configuring certificate server (pki-tomcatd): Estimated time 3 minutes 30 seconds [1/19]: creating certificate server user [2/19]: configuring certificate server instance [3/19]: stopping certificate server instance to update CS.cfg [4/19]: disabling nonces [5/19]: set up CRL publishing [6/19]: starting certificate server instance
Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.
CA did not start in 300s

Also, what is the output of :
certutil -L -d /var/lib/pki/pki-tomcat/alias

sh-4.2# certutil -L -d /var/lib/pki/pki-tomcat/alias
Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI

auditSigningCert cert-pki-ca u,u,Pu

ocspSigningCert cert-pki-ca u,u,u
subsystemCert cert-pki-ca u,u,u

and please attach /etc/pki/pki-tomcat/ca/CS.cfg

Comment from lslebodn at 2014-01-31 16:54:55

I changed line in CA.cfg
ca.cert.list=signing,ocsp_signing,sslserver,subsystem,audit_signing with: ca.cert.list=signing,ocsp_signing,subsystem,audit_signing

Ok — thanks for the info.

So, the correct way for us to reproduce this :

install freeipa on f19
update to f20
create a freeipa replica

We’ll try to reproduce this — and hopefully will run into your issue. We’ll update the ticket as soon as we have results.

Thanks for the patience.

Just a preliminary report of my finding so far.

As an experiment, I asked Endi to issue a new SSL server cert from the master ca (instead of the clone), and then import into the clone ca, then the clone ca started.
At one point, I suspected that even if such clone ca (with a new SSL cert issued from the master) might not issue certs correctly (given the wrong initial SSL server cert issuance), but another experiment proved that it actually did. Once the clone was up, I was able to verify successfully a new ssl server cert issued by this clone.

Currently I am asking Endi to try out a possible workaround in the CS.cfg. He will let us know if it works.

As to why it happened, I suspect it has to do with https://fedorahosted.org/pki/ticket/448, which would cause the default encoding to change from PrintableString to UTF8String. However, regardless of the change, the CA should never change its issuer DN encoding, so I am sure there is a bug in the CA.

Дополнительно: Root android wear

X500Name.directoryStringEncodingOrder=PrintableString,UTF8String,T61String,BMPString,UniversalString

The replica’s SSL server cert’s issuer DN is encoded with PrintableString.

(not permanent) automate the workaround (X500Name.directoryStringEncodingOrder param in CS.cfg) into (IPA/Dogtag) installation script(s). Please note that this is not a permanent solution as it makes assumption about what the CA signing cert’s encoding was.
(permanent and preferred) fix in Dogtag so that in the cloning procedure, submit the clone’s SSL server cert CSR to the master CA instead. This will guarantee the correct encodings, and totally avoid asking the clone ca to issue certs in the time period when the clone is still unstable.

Choice could be based on how much time each solution will take to complete and how urgent IPA needs the fix.

Hi,
thanks for your work.

I’m getting the above error — I’ve searched other answers but I am using Mysql and no proxy, so, they didn’t help.

Basically, I have Jira/Bitbucket/Bamboo/Confluence on a single server — the other 3 apps work fine and are setup on MySQL, I didn’t realise that when I installed Confluence, it was using the embedded database.

It worked fine for a while (using the quickstart/demo files) and we only had about 2 pages in there (only just started using it), and all of a sudden, it would just lag out after clicking edit.

When I logged in, it gave me the health warning that I was using the embedded database.

I uninstalled Confluence and deleted the home directory and application directory (after taking a backup). I then reinstalled the latest version as my installed version was a bit old.

Setup ran fine, I copied over the Mysql java file (same one I used for JIRA), and it passed the database test. Only thing out of the ordinary was I had to type «set global transaction isolation level READ COMMITTED» in SQL due to getting the error.
