I am trying to get a CSV from the report using this well-known plugin and the example from its documentation, but it throws an exception. I wonder why, because I just copied most of the code from the doc.
My code is:
import java.io.FileInputStream;

Platform.startup(config);
IReportEngineFactory factory = (IReportEngineFactory) Platform.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
engine = factory.createReportEngine(config);
engine.changeLogLevel(Level.FINE);
IReportRunnable design = engine.openReportDesign(fs);
IRunAndRenderTask task = engine.createRunAndRenderTask(design);
CSVRenderOption csvOption = new CSVRenderOption();
String format = CSVRenderOption.OUTPUT_FORMAT_CSV;
csvOption.setOutputFormat(format);
csvOption.setOutputFileName("newBIRTcsv.csv");
csvOption.setShowDatatypeInSecondRow(true);
csvOption.setExportTableByName("SecondTable");
csvOption.setDelimiter("\t");
csvOption.setReplaceDelimiterInsideTextWith("-");
task.setRenderOption(csvOption);
task.setEmitterID("org.eclipse.birt.report.engine.emitter.csv");
task.run();
task.close();
Platform.shutdown();
System.out.println("Report Generated Sucessfully!!");
}
public static void main(String[] args) {
try {
runReport();
} catch (Exception e) {
e.printStackTrace();
}
}
}
I am getting the exception:

I found the package org.eclipse.core.runtime and registered in the build path, but then I am getting the same exception. Indeed, there are no any CoreException.class in the org.eclipse.core.runtime package. What am I doing wrong?
Setting the engine home is deprecated and most of the time it will prevent the Platform to start, such in your case. Remove this line:
config.setEngineHome("C:\\birtre\\birt-runtime-4_3_2\\");
You just have to ensure the birt runtime 4.3.2 is in the classpath of your context. Furthermore i would recommend you try to generate a native format such pdf first, and then try with a csv format.
I was trying a lot of variants of importing different jars, but finally i found the weird decision here:
go to the Project Explorer, right-mouse click on properties for the
project, go to Java Build path, Click on the External Jars button,
then select all the libraries under
C:\birt_runtime\birt-runtime-2_1_0\ReportEngine\lib\ folder
This made chaos there, but at least it starts.

I try with the following Bouncy crypt library
bcprov-jdk15on-157.jar
bcprov-jdk15on-152.jar
bcprov-jdk15on-151.jar
bcprov-jdk15on-150.jar
bcprov-jdk15on-149.jar
Finally I solved my problem changing the library jackcess-encrypt-2.1.2.jar by jackcess-encrypt-2.1.0.jar.
I don´t know why but this made me possible did this work.
Should be fixed in the jackcess-encrypt 2.1.3 release.

I have a problem, and it's that when I try to use HikariCP in my project, it returns in an error (the title one).
I'm using it in a BungeeCord plugin.
The weird thing is that I have done this successfully couples of times, and I don't know why it isn't working this time.
The error / log:

My procedure:
Create the project, import BungeeCord.jar, HikariCP-2.6.0.jar and slf4j-api-1.7.21.jar in buildpath, import HikariCP-2.6.0.jar and slf4j-api-1.7.21.jar
It worked in other projects, but magically, it's broken.
I don't want to use Maven, just because it must have a fix, because as I said, I used this same procedure so many times in the past.
Thank you for taking the time to read this :)
EDIT:
Image of the project
It's all in the exception:
Caused by: java.lang.ClassNotFoundException: com.zaxxer.hikari.HikariDataSource
The HikariDataSource is missing at runtime, you need to provide it somehow, for example by copying the relevant .jar with 'drivers' into your server libraries folder.
Also see some related questions:
How to set up datasource with Spring for HikariCP? and
How do I configure HikariCP in my Spring Boot app in my application.properties files?
From the exception it is clear that HikariCP-2.6.0.jar was in classpath during compile time but is missing in runtime and from the image of the project structure, it is also clear that both HikariCP-2.6.0.jar and slf4j-api-1.7.21.jar are missing as library reference in the ide. You need to keep these jar in your classpath library during compile time and runtime.
I am an absolute newbee in asterisk. I am trying to use asterisk-java for event listening through AMI. I am currently using the version 11.2.1 asterisk. When I tries to compiles the code as
javac -cp asterisk-java-0.3.jar HelloEvents.java
it complets successfully. But when I try to execute the file, I give the following error.

}
public static void main(String[] args) throws Exception
{
HelloEvents helloEvents;
helloEvents = new HelloEvents();
helloEvents.run();
}
}
java -cp ".;asterisk-java.jar" HelloEvents
works fine.
And the class path separator is OS dependent. If you are using linux / mac, use : (colon) instead of ; (semicolon)
We can avoid adding class path every time while compiling or executing code. Now go to the location where jar file is located. Then run,
For linux :- export CLASSPATH=$CLASSPATH:asterisk-java-2.0.3.jar:.
For windows:- set CLASSPATH=$CLASSPATH:asterisk-java-2.0.3.jar:.
Now compile code by
javac HelloEvents.java
Execute it by java HelloEvents

How to download & save image correctly?
I guess you just need to specify path to your class
"C:\Program Files\Java\jdk1.6.0_22\bin\java.exe" -classpath <path to your class> loadapicture

It seems to me that the the problem comes from FileDataModel.java, which belongs to this libary itself. How to trace back or analyze this error.
The example code is given as follows, which exactly is the one copied from the book. The line causing the trouble is
DataModel model = new FileDataModel(new File("intro.csv"));
import org.apache.mahout.cf.taste.impl.model.file.*;
import org.apache.mahout.cf.taste.impl.neighborhood.*;
import org.apache.mahout.cf.taste.impl.recommender.*;
import org.apache.mahout.cf.taste.impl.similarity.*;
import org.apache.mahout.cf.taste.model.*;
import org.apache.mahout.cf.taste.neighborhood.*;
import org.apache.mahout.cf.taste.recommender.*;
import org.apache.mahout.cf.taste.similarity.*;
import java.io.*;
import java.util.*;
class RecommenderIntro {
public static void main(String[] args) throws Exception {
DataModel model = new FileDataModel(new File("intro.csv"));
UserSimilarity similarity = new PearsonCorrelationSimilarity(model);
UserNeighborhood neighborhood =
new NearestNUserNeighborhood(2, similarity, model);
Recommender recommender = new GenericUserBasedRecommender(
model, neighborhood, similarity);
List<RecommendedItem> recommendations =
recommender.recommend(1, 1);
for (RecommendedItem recommendation : recommendations) {
System.out.println(recommendation);
}
}
}
It looks like the SLF4J dependency is not installed/on the classpath: slf4j-api.jar
