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
at org.apache.ibatis.datasource.unpooled.UnpooledDataSource.initializeDriver(UnpooledDataSource.java:179)

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

Below is what i have where the code fails at globalSetUp()
Below is also relevant code
and Appium server says
Hello all, trying to get appium working for the first time as a novice, would like to know what i can do over at pom.xml or what can i do to resolve this problem.
Thanks!
Add a SLF4J implementation:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.30</version>
</dependency>
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 attempting introduce high availability mode (via JBoss Cache) in my server implementation (essentially an expanded version of the example server) by configuring my Maven project to use jdiameter-ha-api and jdiameter-ha-impl dependencies instead of jdiameter-api and jdiameter-impl, in addition to adding the following extensions to jdiameter-config.xml:
<Extensions>
<SessionDatasource value="org.mobicents.diameter.impl.ha.data.ReplicatedSessionDatasource"/>
<TimerFacility value="org.mobicents.diameter.impl.ha.timer.ReplicatedTimerFacilityImpl"/>
</Extensions>
Now, when I run the server from Eclipse, it works fine, i.e. it start up in clustered mode (w/ JBoss Cache), however, when I attempt to run the jar produced by mvn install, it throws the following error:

Given that it starts up in Eclipse just fine, I'm assuming my POM file isn't managing dependencies properly, so that the final jar is missing these classes. Here's the relevant portion of my pom.xml:

<artifactId>jdiameter-ha-api</artifactId>
<version>${restcomm.diameter.jdiameter.version}</version>

Following is my pom entries:
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>transport</artifactId>
<version>6.2.4</version>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
I have tried using the log4j-core and log4j-api pom entries also, but still getting the same error. I also saw the dependency tree and found two conflicting versions of commons-logging:commons-logging:jar , but I don't know how to solve this.
Can anyone tell me what is the issue and how to solve this.
Please try with this dependency:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>log4j-over-slf4j</artifactId>
<version>1.7.25</version>
</dependency>
Often, you can resolve such exceptions by searching for the full class name on search.maven.org.
I'm using the Java API. I tried the following:
Client client = TransportClient.builder().build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9200));

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();
