How to use BulkProcessor in version 8 +

I'm upgrading from elasticsearch 7 client to 8 and trying to stop using the deprecated RestHighLevelClient. The issue is that in one of the modules i am having BulkProcessor, and i can't figure out how I can use it with the new clients library, since none of them is compatible.
public static Builder builder(Client client, Listener listener, Scheduler flushScheduler, Scheduler retryScheduler, Runnable onClose) {
Objects.requireNonNull(client, "client");
Objects.requireNonNull(listener, "listener");
return new Builder(client::bulk, listener, flushScheduler, retryScheduler, onClose);
}
The builder above expects package org.elasticsearch.client.internal.Client and i don't find any implementation i can use in any of the dependencies below:
<dependency>
<groupId>co.elastic.clients</groupId>
<artifactId>elasticsearch-java</artifactId>
<version>8.3.2</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-client</artifactId>
<version>8.3.2</version>
</dependency>
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>8.3.2</version>
</dependency>
Am i missing something?
Thank you!

LongComparator does not work in Google Cloud Bigtable with HBase API

I'm trying to build some filters to filter data from Bigtable. I'm using bigtable-hbase drivers and HBase drivers. Actually here are my dependencies from pom.xml:
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-common</artifactId>
<version>${hbase.version}</version>
</dependency>
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-protocol</artifactId>
<version>${hbase.version}</version>
</dependency>
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-client</artifactId>
<version>${hbase.version}</version>
</dependency>
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-server</artifactId>
<version>${hbase.version}</version>
</dependency>
<dependency>
<groupId>com.google.cloud.bigtable</groupId>
<artifactId>bigtable-hbase</artifactId>
<version>${bigtable.version}</version>
</dependency>
I'm filtering data like this:
Filter filterName = new SingleColumnValueFilter(Bytes.toBytes("FName"), Bytes.toBytes("FName"),
CompareFilter.CompareOp.EQUAL, new RegexStringComparator("JOHN"));
FilterList filters = new FilterList();
filters.addFilter(filterName);
Scan scan1 = new Scan();
scan1.setFilter(filters);
This works ok. But then I add following to previous code:
Filter filterSalary = new SingleColumnValueFilter(Bytes.toBytes("Salary"), Bytes.toBytes("Salary"),
CompareFilter.CompareOp.GREATER_OR_EQUAL, new LongComparator(100000));
filters.addFilter(filterSalary);
and it give me this exception:
Exception in thread "main" com.google.cloud.bigtable.hbase.adapters.filters.UnsupportedFilterException: Unsupported filters encountered: FilterSupportStatus{isSupported=false, reason='ValueFilter must have either a BinaryComparator with any compareOp or a RegexStringComparator with an EQUAL compareOp. Found (LongComparator, GREATER_OR_EQUAL)'}
at com.google.cloud.bigtable.hbase.adapters.filters.FilterAdapter.throwIfUnsupportedFilter(FilterAdapter.java:144)
at com.google.cloud.bigtable.hbase.adapters.ScanAdapter.throwIfUnsupportedScan(ScanAdapter.java:55)

at com.google.cloud.bigtable.hbase.adapters.ScanAdapter.adapt(ScanAdapter.java:43)
at com.google.cloud.bigtable.hbase.BigtableTable.getScanner(BigtableTable.java:247)
So my question is how to filter long data type? Is it hbase issue or bigtable specific?
I found this How do you use a custom comparator with SingleColumnValueFilter on HBase? but I can't load my jars to server so it is not applicable for my case.

SingleColumnValueFilter supports the following comparators:
BinaryComparator
BinaryPrefixComparator
RegexStringComparator.

Trouble starting Hibernate Validator due to Bean Validation API

I'm trying to use Hibernate Validator in my project, but it isn't working. On the following line:
SessionFactory sessions = config.buildSessionFactory(builder.build());
I get the following exception:
org.hibernate.cfg.beanvalidation.IntegrationException: Error activating Bean Validation integration
at org.hibernate.cfg.beanvalidation.BeanValidationIntegrator.integrate(BeanValidationIntegrator.java:154)

at javax.validation.Validation.buildDefaultValidatorFactory(Validation.java:111)
I found this question which seems quite similar to my problem. He describes his solution as
I had yet another bean validator jar in the class path. But not from
maven, so i didn't realize it. Removing that solved the problem.
I think my problem is the same. On http://hibernate.org/validator/documentation/getting-started/ it says:
This transitively pulls in the dependency to the Bean Validation API
(javax.validation:validation-api:1.1.0.Final)
That must be causing this issue, since reverting to an older version (4.3.1.Final) fixes the issue. Is there a way to force Hibernate to not pull in the Bean Validation API?
Edit: I've tried to exclude the javax-validation api:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.0.3.Final</version>
<exclusions>
<exclusion>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
</exclusion>
</exclusions>
</dependency>
But it didn't seem to have any effect.

Try adding this dependency to your pom.xml
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.0.0.GA</version>
</dependency>
If not consider using hibernate-validator4.2.0.Final I have that one in my config and it is working fine.

For me, the 1.1.0.Final version javax.validation.validation-api had worked. Because, the javax.validation.spi.ConfigurationState interface of 1.1.0.Final has getParameterNameProvider method, which was absent in 1.0.0.GA.
I added the below dependency in pom.xml
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1.0.Final</version>
<scope>test</scope>
</dependency>

I had the problem again. Thats how I've fixed that:
1-Exclude spring.validator from the 'web' dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.hibernate.validator</groupId>
<artifactId>hibernate-validator</artifactId>
</exclusion>
</exclusions>
</dependency>
2-After insert the dependecy with a previous version:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.1.3.Final</version>
</dependency>

in my case i just deleted the hibernate-validator and it worked .(i also had a combo of both validation api and hibernate-validator and tried everything) or you can go to your maven repository-->org and then delete the hibernate folder and rebuild your project again..
hope it helps..

I thought it would be useful to explain what is going on here.
Hibernate is calling ConfigurationState.getParameterNameProvider:
ValidatorFactoryImpl.java:
public ValidatorFactoryImpl(ConfigurationState configurationState) {
...
configurationState.getParameterNameProvider()
...
}
You can find the documentation of getParameterNameProvider:
getParameterNameProvider
ParameterNameProvider getParameterNameProvider()
Returns the parameter name provider for this configuration.
Returns:
parameter name provider instance or null if not defined
Since:
1.1
So what's the problem? The problem is that the method didn't always exist. It was added at some point in the future.
And the rule when creating interfaces is that they are set in concrete: you shall not change an interface ever. Instead the JavaX validator changed the ConfigurationState interface, and added a few new methods over the years.
The java validation code is passing the Hiberate an outdated ConfiguationState interface; one that doesn't implement the required interfaces.
You need to ensure that javax.validation.Validation.buildDefaultValidatorFactory is updated to to support version 1.1.

Removing this jar javax.validation:validation-api:1.1.0.Final solved my problem.
Make sure you have only one validation jar. If we have two jars then they may conflict resulting in error.

Go to the dependecies project and delete, hibernate.validator, and reinstall that in the most recent version. It has solved the problem for me.

exception: java.lang.NoSuchMethodError: com.lowagie.text.pdf.PdfWriter.setRgbTransparencyBlending(Z)V

guys! For long time I can't fix the exception: java.lang.NoSuchMethodError: com.lowagie.text.pdf.PdfWriter.setRgbTransparencyBlending(Z)V
I've add all need jars into classpath:
commons-beanutils-1.8.0
commons-collections-2.1.1
commons-digester-2.1.0
commons-javaflow-20060411
commons-logging-1.1.1
itext - 2.1.5

I can create the instance of PdfWriter class (for check myself)
Thank you for your help

jasperreports-5.1.0 needs itext-2.1.7.
You can see it in the pom of the jasperreports-5.1.0 project:
<dependency>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
<version>2.1.7.js2</version>
<scope>compile</scope>
</dependency>
You need to upgrade the version of itext to version 2.1.7 minimum.

I had the same [runtime] error. What I realized was, I had the wrong jars for the "batik" library. I got all version 1.7 jars from the org.apache.xmlgraphics. I'm using jasper in this way:
<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>4.0.0</version>
</dependency>
The batik, for example:
<dependency>
<groupId>org.apache.xmlgraphics</groupId>
<artifactId>batik-anim</artifactId>
<version>1.7</version>
</dependency>
Also, I made sure I only had one instance of iText in the pom:
<dependency>
<groupId>com.lowagie</groupId>
<artifactId>iText</artifactId>
<version>2.1.7</version>
</dependency>
Hope that helps.

I had the same issue, when retrieving data from grid and writing to a PDF using
flying-saucer-pdf
The isuue was com.lowagie (itext) and org.xhtmlrenderer (flying-saucer-pdf) versions incompatible,
use following,
<dependency>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
<version>2.1.7</version>
</dependency>
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-pdf</artifactId>
<version>9.0.7</version>
</dependency>

I have also came across same situation but finally succeeded to resolve it.
If you are using maven then add below dependency
<dependency>
<groupId>org.eclipse.birt.runtime.3_7_1</groupId>
<artifactId>com.lowagie.text</artifactId>
<version>2.1.7</version>
</dependency>
or download jar from below link and add to your buildpath
com.lowagie.text_2.1.7
It will be of no use to add itext-2.1.7.jar , Also the latest version of that is itextpdf-5.5.9.jar

If M. Abbas answer does not work then please use this dependency:
<dependency>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
<version>2.1.7</version>
</dependency>
It works for me.

ClassNotFound exception using Jackson ObjectMapper

I have a Spring 3 MVC app that I am setting up some ajax actions for.
My controller action looks like this:
#RequestMapping(value="add", method=RequestMethod.POST)
#Secured("ROLE_USER")
#ResponseStatus(HttpStatus.CREATED)
public #ResponseBody Plan addPlan(#RequestBody Plan plan, Principal principal) {
//Save the plan
}
When I post the Plan data from my browser the app throws a ClassNotFound exception:
java.lang.ClassNotFoundException: org.joda.time.ReadableInstant not found by jackson-mapper-asl [176]
at org.apache.felix.framework.ModuleImpl.findClassOrResourceByDelegation(ModuleImpl.java:787)

at org.apache.felix.framework.ModuleImpl$ModuleClassLoader.loadClass(ModuleImpl.java:1768)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
The Plan object itself does not contain any joda-date types. Though it contains a collection of objects that do. Originally I was pulling in the joda-date jar via my DOA jar but the error persists even if I add a direct dependency to my web project's pom.xml. I'm using the joda classes elsewhere in this project without any issue.
Additional information
Here are the relevant dependencies from my web pom.xml:

I somehow came across this question: Apache FTP server is not seeing a logging jar package that exists in the class path
Their solution of setting <class-loader delegate="false"> in glassfish-web.xml seems to have fixed my issues.

I've reported this on Glassfish JIRA https://java.net/jira/browse/GLASSFISH-20808
