I am building web application using Spring and Hibernate. I am using Tomcat version 9.0 and mysql-connector-java-8.0.12.jar
I am trying to run my program using Tomcat, I am getting this error.
Any help would be appreciated. I tried all the solutions but none worked for me.

I had similar problem. Changing jdbc.url to
jdbc.url=jdbc:mysql://localhost:3306/web_customer_tracker?allowPublicKeyRetrieval=true&useSSL=false&serverTimezone=UTC
worked for me.
url="jdbc:mysql://localhost:3306/web_student_tracker?useSSL=true
I had a similar problem when I was doing the project, but its very simple just update mysql connector jar file (mysql-connector-java-8.0.12) to (mysql-connector-java-8.0.12) and it's working fine.
I had the same problem when I was doing the same course on Udemy, I fixed it just updating my mysql connector, now I am using (mysql-connector-java-8.0.16.jar) instead of (mysql-connector-java-8.0.12.jar)

I get the DB username and password from my java program which is correct and verified.
The issue is when I run this program the account gets locked immediately at the DB level not sure what is causing this issue.
Error Logs states as follows:-

Any pointers on what might be the issue in here.
Thanks.
Some process is trying to log in to that account using an incorrect password. The guess guess would be that the account is being locked because it's exceeding the number of allowed incorrect logins.
You can unlock the account like below.
ALTER USER USER_NAME ACCOUNT UNLOCK;

I have created a test application in Hibernate and using Oracle 12c as database. I was able to connect to "sys" user of main database. I am able to create, insert, update the tables in this DB. But I am unable to connect to pluggable database. Is there any way to connect to PDB using hibernate. Test is my main DB and pdborcl is my PDB. I also tried google for this, but there is no post on Hibernate and Oracle 12c, but nothing specific to PDB. There is this article which says there is no support for 12c. https://github.com/denimgroup/threadfix/issues/488 Is this true?
As far as my understanding of Oracle 12c goes, CDB is only for administration purposes and PDB will be the database used for application purposes.

When I try to connect to PDB by changing test to pdborcl it gives me below exception. I am able to ping both test and pdborcl from my system. I am also able to connect to both DBs using sqlplus from terminal.
I get below exception when I try to connect to PDB.

Your syntax is slightly wrong. Make sure you use the /SERVICE_NAME not the :SID.
For jdbc to connect to a pluggable database, :SID can no longer be used. (well, it can but don't go there)
Accessing an Oracle Database by service_name is the correct approach since Oracle 8i. And that is 100 it-years ago!
jdbc:oracle:thin:#localhost:1521/my_pdb_service_name
You will find available services by asking the listener
lsnrctl service
The sys account is a special account. Sys has the same meaning for the database as the root user has for the OS. You can do harm with these users! Instead create an application account/user.
create user mysuperapp identified by "Neverloginassys";
grant create session to mysuperapp;

I'm testing web application with hibernate 4.3.0 and c3p0 pool and sometimes after reloading context I get this error:

What is the reason for that error and hot to fix it?
All dependecies related to hibernate-c3p0 are in the classpath.
Please refer to the links I added as comments. During re-deployment classes are unloaded, if you fail to close Hibernate's sessionFactory then you get these ClassNotFound errors. One of the answer suggest that you can add a custom ServletContextListener to handle the contextDestroyed event.
I am trying to pull remote files through SFTP Spring Integration and dump into my local drive, and kick-off a Spring Batch Job (Step-1 to read, process & write), followed by Step-2 where a Tasklet archives the local file downloaded to another location locally and deletes the downloaded file.
Assuming the files being downloaded is "data.service", "data.maintenance" and "data.transaction". I am only processing "data.service" but all 3 are archived and deleted.
I want the above steps to happen at a specific interval assuming that a new set of files will be overwritten at the remote location.
Bean def
<bean id="acceptAllFileListFilter" class="org.springframework.integration.file.filters.AcceptAllFileListFilter"/>
<bean id="acceptOnceFileListFilter" class="org.springframework.integration.file.filters.AcceptOnceFileListFilter"/>
conf
<int-sftp:inbound-channel-adapter id="sftpInbondAdapter"
channel="inboundFileChannel"
session-factory="sftpSessionFactory"
local-directory="file:${inbound.local.directory}"
remote-directory="${inbound.remote.directory}"
auto-create-local-directory="true"
delete-remote-files="false"
preserve-timestamp="true"
filename-pattern="*.*"
local-filter="acceptAllFileListFilter" >
<int:poller max-messages-per-poll="-1" fixed-rate="60000" />
</int-sftp:inbound-channel-adapter>
What is happening now is...
The above triggers this sequence and runs in an unending loop, without fetching the new files from remote. Details as below:
I start with an empty local folder, and remote server has all 3 files
[Start the program]
Spring Integration program downloads all 3 files to local location
Spring Batch Job Step-1 gets triggered Tasklet (Step-2) archives the
local files Tasklet (Step-2) deletes the local files Spring
Integration program downloads all 3 files to local location (why???)
program keeps running Step-1 to Step-5 in an unending loop
New file dropped on the remote server, same (1) to (5) no job triggered
Tried replacing as below, but the program just runs once, i.e., from (1) to (5) and nothing happens
local-filter="acceptOnceFileListFilter" >
Expected
Spring Integration program downloads all 3 files to local location
Spring Batch Job Step-1 gets triggered
Tasklet (Step-2) archives the local files
Tasklet (Step-2) deletes the local files
Spring Integration program waits for new files to be dropped in the remote location (polls every 60000 ms)
New file dropped on the remote server
Start with (1) through (6)
Per suggestion on a different post I have a unique job parameter as below:
#Transformer
public JobLaunchRequest toRequest(Message<File> message) {
JobParametersBuilder jobParametersBuilder = new JobParametersBuilder();
jobParametersBuilder.addString(fileParameterName, message.getPayload().getAbsolutePath());
jobParametersBuilder.addLong("currentTime", new Long(System.currentTimeMillis()));
return new JobLaunchRequest(job, jobParametersBuilder.toJobParameters());
}
Tried with different combinations of filter, none served my purpose. Any sample would be of great help, struggling with this since last week.
Here's my change per the suggestions:
Adding a composite filter as below, but what would be the argument that will be passed to SftpPersistentAcceptOnceFileListFilter? I could not see any samples in the internet.
<bean id="compositeFilter" class="org.springframework.integration.file.filters.CompositeFileListFilter">
<constructor-arg>
<list>
<bean class="org.springframework.integration.file.filters.FileSystemPersistentAcceptOnceFileListFilter"/>
<bean class="org.springframework.integration.sftp.filters.SftpPersistentAcceptOnceFileListFilter">
</bean>
</list>
</constructor-arg>
</bean>
Including in the adapter as below:
<int-sftp:inbound-channel-adapter id="sftpInbondAdapter"
channel="inboundFileChannel"
session-factory="sftpSessionFactory"
local-directory="file:${inbound.local.directory}"
remote-directory="${inbound.remote.directory}"
auto-create-local-directory="true"
delete-remote-files="false"
filter="compositeFilter">
<int:poller max-messages-per-poll="-1" fixed-rate="600000" />
</int-sftp:inbound-channel-adapter>
Update - Changes after adding persistent filter:
<int-sftp:inbound-channel-adapter id="sftpInbondAdapter"
channel="inboundFileChannel"
session-factory="sftpSessionFactory"
local-directory="file:${inbound.local.directory}"
remote-directory="file:${inbound.remote.directory}"
auto-create-local-directory="false"
delete-remote-files="false"
filter="compositeFilter"
>
<int:poller max-messages-per-poll="-1" fixed-rate="60000" />
</int-sftp:inbound-channel-adapter>
<bean id="compositeFilter" class="org.springframework.integration.file.filters.CompositeFileListFilter">

<constructor-arg name="store" ref="metadataStore"/>
<constructor-arg value="*.*"/>
</bean>
<bean class="org.springframework.integration.sftp.filters.SftpPersistentAcceptOnceFileListFilter">

<constructor-arg value="*.*"/>
</bean>
</list>
</constructor-arg>
</bean>
<bean id="redisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">

</bean>
<bean name="metadataStore" class="org.springframework.integration.redis.metadata.RedisMetadataStore">
<constructor-arg name="connectionFactory" ref="redisConnectionFactory"/>
</bean>
This gives me the exception as below. I tried the suggestions in the Spring forum, but I don't have a connection issues.

Hopefully self-explanatory; it just prints the file name on the console, then deletes it.
It could be the case that if the new files dropped on the server has same name(which are downloaded in the first iteration) then spring integration will not attempt to download the files again. "acceptOnceFileListFilter" seems like something that would restrict sftp integration component to download the same file again.
Update: Here is some sample code which polls a remote directory every 10 secs without introducing any filters(I am not sure why you need them, as you want to download the files regardless). Given that you dont want to change the file names, the only thing that you will have to make sure is that your downloaded local needs to deleted when the next file is dropped on the remote server. I verified it and worked fine for me.

But i have added spring-web-mvc to my class path which does contain this class file.

How did you add something to your CLASSPATH?
If you're creating a web app, the only appropriate thing is to put .class files under WEB-INF/classes and .jar files under WEB-INF/lib. If you did anything else, I'd say that it's wrong. Modifications of the startup script should not be done; local environment variables will be ignored and unlikely to be set on the server you deploy to.
UPDATE:
If you tell me that you've done everything right according to your IDE, I'd recommend one last check: Look at the zipped or exploded WAR file that you actually deploy to Tomcat and make sure that you can see the JAR with the .class file that the error mentions. If it's not part of the WAR, you have to figure out what went wrong with your packaging. If you think the JAR is there, open it and find the .class and check the path.
You have to believe the error message you see. Instead of saying "I'm doing everything right", it's better to say "What have I missed?"
A ClassNotFoundException suggests that you don't have Spring on the classpath. Make sure it's in your WAR's lib directory.
Also, make sure you also have commons-logging.jar in your classpath. Spring depends on this.
