I'm trying to deploy a bundle in karaf. I want to create a process engine inside of it which connects to h2 database. I have the dependency in pom.xml:
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<version>1.4.190</version>
</dependency>
In ini() method I try to create engine process using:
ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration()
.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE)
.setJdbcUrl("jdbc:h2:mem:my-own-db;DB_CLOSE_DELAY=1000")
.setJobExecutorActivate(true)
.buildProcessEngine();
Nevertheless, in karaf console when I deploy the bundle I got the error:
Caused by: org.apache.ibatis.datasource.DataSourceException: Error setting driver on UnpooledDataSource. Cause: java.lang.ClassNotFoundException: org.h2.Driver

Could you print the built MANIFEST ?
And the result of bundle:headers
I guess your bundle try to import h2 Driver because you did not set it to private.
Quick fix, in karaf, run
bundle:install mvn:com.h2database/h2/1.4.199
This pertains to a GitHub issue where TensorFlow is being loaded at runtime for native image:
https://github.com/awslabs/djl/issues/103#issuecomment-658549779
It causes a io.netty.internal.tcnative.SSLPrivateKeyMethod class not found error during native image compilation. If I add this dependency, the error goes away:
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-tcnative</artifactId>
<version>2.0.31.Final</version>
</dependency>

It is definitely related to one of the following configs, and does also seem to be impacted by JNI, but I am not sure how.
quarkus.native.enable-jni=true
quarkus.ssl.native=true
quarkus.native.additional-build-args=--initialize-at-run-time=org.tensorflow\\,ai.djl\\,org.bytedeco
In searching through the Quarkus GitHub repos, I cannot find reference to netty-tcnative. I really do not understand why this is needed as it seems to be related to Tomcat?
In order to fix this problem, or file a GitHub issue, need to understand where this dependency is expected.
I'm using the Java API. I tried the following:

I am using Elasticsearch 2.0.0 and it is running on port 9200
What is causing that error and how can I fix it?
I have this problem too, but when i add the guava-18.0.jar into build path ,it works. Hope it works for you.
You can use Unirest API for Java. It is very easy to use.
http://unirest.io/java.html
Check it's documentation. I myself am a beginner and I found this very easy to implement.
Just add the following maven dependency in your pom file.
<dependency>
<groupId>com.mashape.unirest</groupId>
<artifactId>unirest-java</artifactId>
<version>1.4.7</version>
</dependency>
And your java implementation would be like this:
HttpResponse<String> response = Unirest.get("http:localhost:9200").asString();

Process finished with exit code 1
for the maven users,
comment the scope provided in the following dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<!--<scope>provided</scope>-->
</dependency>
UPDATE
As feed.me mentioned you have to uncomment the provided part depending on what kind of app you are deploying.
Here is a useful link with the details:
http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#build-tool-plugins-maven-packaging
It's not good to change the scope of your application dependencies. Putting the dependency as compile, will provide the dependency also in your artifact that will be installed somewere.
The best think to do is configure the RUN configuration of your sping boot application by specifying as stated in documentation :
"Include dependencies with 'Provided' scope" "Enable this option to
add dependencies with the Provided scope to the runtime classpath."
providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
This should be
compile("org.springframework.boot:spring-boot-starter-tomcat")
It's interesting things with IDE (IntelliJ in this case):
if you leave default, i.e. don't declare spring-boot-starter-tomcat as provided, a spring-boot-maven-plugin (SBMP) put tomcat's jars to your war -> and you'll probably get errors deploying this war to container (there could be a versions conflict)
else you'll get classpath with no compile dependency on tomcat-embed (SBMP will build executable war/jar with provided deps included anyway)
intelliJ honestly doesn't see provided deps at runtime (they are not in classpath) when you run its Spring Boot run configuration.
and with no tomcat-embed you can't run Spring-Boot with embedded servlet container.
There is some tricky workaround: put Tomcat's jars to classpath of your idea-module via UI: File->Project Structure->(Libraries or Modules/Dependencies tab) .
tomcat-embed-core
tomcat-embed-el
tomcat-embed-websocket
tomcat-embed-logging-juli
Better solution for maven case
Instead of adding module dependencies in Idea, it is better to declare maven profile with compile scope of spring-boot-starter-tomcat library.
<profiles>
<profile>
<id>embed-tomcat</id>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>compile</scope>
</dependency>
</dependencies>
</profile>
</profiles>
while spring-boot-starter-tomcat was declared provided in <dependencies/>, making this profile active in IDE or CLI (mvn -Pembed-tomcat ...) allow you to launch build with embedded tomcat.
Add the following dependency. The scope should be compile then it will work.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>compile</scope>
</dependency>
In my case scope of that dependency was provided.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
So, I was getting the same issue.
Caused by: java.lang.ClassNotFoundException: javax.servlet.Filter
I had to enable the below option in Intellij
Add dependencies with "provided" scope to classpath
You will see below option enabled,
OR
You can add the below property to .intellij/workspace.xml file under your application configuration section.
<option name="INCLUDE_PROVIDED_SCOPE" value="true" />
e.g.,
<component name="RunManager" selected="Application.DemoApp">
<configuration name="DemoApp" type="Application" factoryName="Application">
<option name="INCLUDE_PROVIDED_SCOPE" value="true" /> ```
For Jar
Add pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
That looks like you tried to add the libraries servlet.jar or servlet-api.jar into your project /lib/ folder, but Tomcat already should provide you with those libraries. Remove them from your project and classpath. Search for that anywhere in your project or classpath and remove it.
The configuration here is working for me:
configurations {
customProvidedRuntime
}
dependencies {
compile(
// Spring Boot dependencies
)
customProvidedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
}
war {
classpath = files(configurations.runtime.minus(configurations.customProvidedRuntime))
}
springBoot {
providedConfiguration = "customProvidedRuntime"
}
2023 Solution
Remove provided from maven of tomcat artifactId
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<!-- Here <scope>provided</scope >-->
</dependency>
I use Zen's Maven plugin to develop my JavaFX 2.2 application using Maven. The following is the plug-in declaration.
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>2.0</version>
<configuration>
<mainClass>${mainClass}</mainClass>
</configuration>
</plugin>
I fixed the classpath using the following command:
mvn com.zenjava:javafx-maven-plugin:2.0:fix-classpath
and the fixing probably succeeded.
The compilation also worked but the process did not generate JavaFX main files such as the following:
/com/javafx/main/Main$1.class
/com/javafx/main/Main$2.class
/com/javafx/main/Main.class
/com/javafx/main/NoJavaFXFallback.class
Running the project produces the following exceptions:

What is going wrong and how can I fix it?
The main jar doesn't contain these classes, but the plugin generates an additional jar in the "target/jfx" directory (or something like this). Use that jar to start your application.
