Configure a p2 update repository programmatically - java

There is an article in the Eclipse wiki how to configure user's p2 default repositories of an RCP application by adding a static conf file to your product:
Equinox/p2/Adding Self-Update to an RCP Application - Configuring the user's default repositories
I want to do the same programmatically in a Java class when the user changes some configuration details. I could not find appropriate p2 API documentation for that.

Use this solution for Eclipse 3.7 based applications:
final ProvisioningUI ui = ProvUIActivator.getDefault().getProvisioningUI();
IArtifactRepositoryManager artifactManager = ProvUI.getArtifactRepositoryManager(ui.getSession());
artifactManager.addRepository(new URI(UPDATE_SITE_URL);
IMetadataRepositoryManager metadataManager = ProvUI.getMetadataRepositoryManager(ui.getSession());
metadataManager.addRepository(new URI(UPDATE_SITE_URL);
For ProvUI and ProvisioningUI you have to import bundles org.eclipse.equinox.p2.ui and org.eclipse.equinox.p2.operations (among others).

I found a solution. It's easy - unfortunately there is no documentation...
// from bundle org.eclipse.equinox.p2.console
import org.eclipse.equinox.internal.p2.console.ProvisioningHelper;
URI repoUri = new URI(UPDATE_SITE_URL);
try {
ProvisioningHelper.addMetadataRepository(repoUri);
} catch( Exception e ) {
LOG.warn("Can not add update repository: " + repoUri);
}
try {
ProvisioningHelper.addArtifactRepository(repoUri);
} catch( Exception e ) {
LOG.warn("Can not add update repository: " + repoUri);
}

Furthermore you can add more than one repositories with ElementUtils and also you can sort them.
MetadataRepositoryElement[] element = new MetadataRepositoryElement[links.length];
for (int i = 0; i < links.length; i++) {
element[i] = new MetadataRepositoryElement(null, new URI(links[i]), true);
element[i].setNickname("Link-"+i);
}
ElementUtils.updateRepositoryUsingElements(element, null);
These links will be appeared alphabetically sorted.

This is high on the Google query for this issue, and there's still not a good way to do it published:
If anyone finds this page via Google as I did, I've solved this problem. You can use org.eclipse.equinox.internal.p2.ui.model.ElementUtils.updateRepositoryUsingElements to set the repositories programmatically. Full code can be found here.

Why httpbuilder is not giving the exact JSON output?

I am trying to get the projectid of my project from JIRA using gradle script.I wrote few methods which basically try to get the JSON output and fetch the project id of that particular project but now i am not able to get the projectId from that. Below is the methods which i am using to get the JSON result. it's working fine but not giving me the exact JSON output.My project Name is TESTPROJECT and id is 12345.I am looking when you have fresh project and need to get the projectid of that project using JIRA request method.I pasted the below JSON output which doesn't have {} "" so not exactly JSON output.Can someone tell me how could I get the project id with below way or am I doing something wrong?

How to use JCo connection without creating *.JcoDestination file

I'm trying to connect to SAP ECC 6.0 using JCo. I'm following this tutorial. However, there is a Note saying:
For this example the destination configuration is stored in a file that is called by the program. In practice you should avoid this for security reasons.
And that is reasonable and understood. But, there is no explenation how to set up secure destination provider.
I found solution in this thread that created custom implementation of DestinationDataProvider and that works on my local machine. But when I deploy it on Portal I get an error saying that there is already registered DestinationDataProvider.
So my question is:
How to store destination data in SAP Java EE application?
Here is my code to further clarify what I'm trying to do.
public static void main(String... args) throws JCoException {
CustomDestinationProviderMap provider = new CustomDestinationProviderMap();
com.sap.conn.jco.ext.Environment.registerDestinationDataProvider(provider);
Properties connectProperties = new Properties();
connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, "host.sap.my.domain.com");
connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR, "00");
connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, "100");
connectProperties.setProperty(DestinationDataProvider.JCO_USER, "user");
connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, "password");
connectProperties.setProperty(DestinationDataProvider.JCO_LANG, "en");
provider.addDestination(DESTINATION_NAME1, connectProperties);
connect();
}
public static void connect() throws JCoException {
String FUNCTION_NAME = "BAPI_EMPLOYEE_GETDATA";
JCoDestination destination = JCoDestinationManager.getDestination(DESTINATION_NAME1);
JCoContext.begin(destination);
JCoFunction function = destination.getRepository().getFunction(FUNCTION_NAME);
if (function == null) {
throw new RuntimeException(FUNCTION_NAME + " not found in SAP.");
}
//function.getImportParameterList().setValue("EMPLOYEE_ID", "48");
function.getImportParameterList().setValue("FSTNAME_M", "ANAKIN");
function.getImportParameterList().setValue("LASTNAME_M", "SKYWALKER");
try {
function.execute(destination);
} catch (AbapException e) {
System.out.println(e.toString());
return;
}
JCoTable table = function.getTableParameterList().getTable("PERSONAL_DATA");
for (int i = 0; i < table.getNumRows(); i++) {
table.setRow(i);
System.out.println(table.getString("PERNO") + '\t' + table.getString("FIRSTNAME") + '\t' + table.getString("LAST_NAME")
+'\t' + table.getString("BIRTHDATE")+'\t' + table.getString("GENDER"));
}
JCoContext.end(destination);
}
Ok, so I got this up and going and thought I'd share my research.
You need to add your own destination in Portal. To achieve that you need to go to NetWeaver Administrator, located at: host:port/nwa. So it'll be something like sapportal.your.domain.com:50000/nwa.
Then you go to Configuration-> Infrastructure-> Destinations and add your destination there. You can leave empty most of the fields like Message Server. The important part is Destination name as it is how you will retrieve it and destination type which should be set to RFC Destination in my case. Try pinging your newly created destination to check if its up and going.
Finally you should be able to get destination by simply calling: JCoDestination destination = JCoDestinationManager.getDestination(DESTINATION_NAME); as it is added to your Portal environment and managed from there.
Take a look at the CustomDestinationDataProvider in the JCo examples of the Jco connector download. The important parts are:
static class MyDestinationDataProvider implements DestinationDataProvider
...
com.sap.conn.jco.ext.Environment.registerDestinationDataProvider(new MyDestinationDataProvider());
Then you can simply do:
instance = JCoDestinationManager.getDestination(DESTINATION_NAME);
Btw. you may also want to check out http://hibersap.org/ as they provide nice ways to store the config as well.

Get the whole index of Maven Central [duplicate]

I have downloaded the indexes generated for Maven Central from http://mirrors.ibiblio.org/pub/mirrors/maven2/dot-index/nexus-maven-repository-index.gz
I would like to list the artifacts information from these index files (groupId, artifactId, version for example). I have read that there is a high level API for that. It seems that I have to use the following maven dependency. However, I don't know what is the entry point to use (which class?) and how to use it to access those files:
<dependency>
<groupId>org.sonatype.nexus</groupId>
<artifactId>nexus-indexer</artifactId>
<version>3.0.4</version>
</dependency>
Take a peek at https://github.com/cstamas/maven-indexer-examples project.
In short: you dont need to download the GZ/ZIP (new/legacy format) manually, it will indexer take care of doing it for you (moreover, it will handle incremental updates for you too, if possible).
GZ is the "new" format, independent of Lucene index-format (hence, independent of Lucene version) containing data only, while the ZIP is "old" format, which is actually plain Lucene 2.4.x index zipped up. No data content change happens currently, but is planned in future.
As I said, there is no data content difference between two, but some fields (like you noticed) are Indexed but not stored on index, hence, if you consume the ZIP format, you will have them searchable, but not retrievable.
The https://github.com/cstamas/maven-indexer-examples is obsolete. And the build fails (tests do not pass).
The Nexus Indexer has moved along and included the examples too:
https://github.com/apache/maven-indexer/tree/master/indexer-examples
That builds, and the code works.
Here is a simplified version if you want to roll your own:

The legacy zip index is a simple lucene index. I was able to open it with Luke
and write some simple lucene code to dump out the headers of interest ("u" in this case)

import org.apache.lucene.search.IndexSearcher;
public class Dumper {
public static void main(String[] args) throws Exception {
IndexSearcher searcher = new IndexSearcher("c:/PROJECTS/Test/index");
for (int i = 0; i < searcher.maxDoc(); i++) {
Document doc = searcher.doc(i);
String metadata = doc.get("u");
if (metadata != null) {
System.out.println(metadata);
}
}
}
}

There may be better ways to achieve this though ...
For the records, there is now a tool to extract and export maven indexes as text files: the Maven index exporter. It's available as a Docker image and no code is required.
It basically downloads all .gz index files, extracts the indexes using maven-indexer cli and exports them to a text file with clue. It has been tested on Maven Central and works on many other Maven repositories.

NoClassDefFoundError for Birt Class EngineException

Has anyone added the Birt Library to a project's build path successfully?
I installed Birt in Eclipse using Help-->Install New Software and copy paste the link for Birt 4.2.2 from the official website. Birt was downloaded from the internet and a new perspective appeared, namely Report Design. Apart from it no Library, no nothing. So I designed my report and started writing Java code in order to do a PDF export of my report, as I found on the internet. I wrote the following:
// Export Birt report
String format = HTMLRenderOption.OUTPUT_FORMAT_PDF;
EngineConfig config = new EngineConfig( );
config.setEngineHome( "C:\\Tools\\Eclipse\\plugins\\org.eclipse.birt.report.viewer_4.2.2.v201302041142\\birt" );
HTMLEmitterConfig hc = new HTMLEmitterConfig( );
HTMLCompleteImageHandler imageHandler = new HTMLCompleteImageHandler( );
hc.setImageHandler( imageHandler );
config.setEmitterConfiguration( HTMLRenderOption.OUTPUT_FORMAT_HTML, hc );
ReportEngine engine = new ReportEngine( config );
IReportRunnable report = null;
String reportFilepath = "C:/Workspace/reports/new_report.rptdesign";
try {
report = engine.openReportDesign( reportFilepath );
}
catch ( EngineException e ) {
System.err.println( "Report " + reportFilepath + " not found!\n" );
engine.destroy( );
return;
}
IRunAndRenderTask task = engine.createRunAndRenderTask( report );
HTMLRenderOption options = new HTMLRenderOption( );
options.setOutputFormat( format );
options.setOutputFileName( "C:/Workspace/reports/output.pdf" );
task.setRenderOption( options );
task.setParameterValues( parametersMap );
try {
task.run( );
}
catch ( EngineException e1 ) {
System.err.println( "Report " + reportFilepath + " run failed.\n" );
System.err.println( e1.toString( ) );
}
engine.destroy( );
return;
Of course no Birt Library is set in my Build Path, so all Birt objects were red. I manually added all Birt jars that existed in Eclipse's plugins folder and all the reds disappeared. It seemed that everything was going great. When I run it I get:
java.lang.NoClassDefFoundError: org/eclipse/birt/report/engine/api/EngineException
while the org.eclipse.birt.report.engine.api package exists in my Build Path
and the EngineException.class exist in the package. I am feeling that there are jar files that I am missing.
I have searched for a solution in Birt home page and found nothing. Most tutorials have instructions regarding how to build a report. But nothing regarding how to get the library up and running with Java.
Is there a standard or automatic or official way to add Birt Library to Eclipse? It is made by Eclipse. It shouldn't be so difficult. Any help will be appreciated.
Have you read this page -> http://wiki.eclipse.org/Servlet_Example_(BIRT)_2.1
Maybe you can find some hints there.

Can not link a Series to a chart SeriesDefinitions in BIRT

I am trying hard to implement a charting extension to an app that i am developing : so my problem is that I have written some code (the boiler plate one) for doing this in BIRT.
At some place in the code, I have to link the dataset to a series and link the series to a seriesdefinition object which finally will be attached to the charts seriesDefinitions like this
RadarSeries radarSeries = RadarSeriesImpl.create();
radarSeries.setDataSet(numberDataValues);
radarSeries.setSeriesIdentifier("Number data values");
radarSeries.getLabel().setVisible(true);
where numberDataValues is an array of doubles. Then I create my seriesDefinition :
SeriesDefinition seriesDefinition = SeriesDefinitionImpl.create();
seriesDefinition.getSeriesPalette().shift(0);
But then, here comes the time when I have to LINK my radarSeries to the seriesDefinition like this :
seriesDefinition.getSeriesDefinitions().add(radarSeries);
THE PROBLEM : I don't have the getSeriesDefinitions() method when trying to call it from code (doing a Ctrl+Space in Eclipse).
Needless to say that I can't call the getSeriesDefinitions() method on myChart object :
myChart.getSeriesDefinitions().add(seriesDefinition);
FOR YOUR INFORMATION : I have included my birt jars manually in my local maven repository and the details of these dependencies are :
<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>engineapi</artifactId>
<version>${birtVersion}</version>
</dependency>
<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>coreapi</artifactId>
<version>${birtVersion}</version>

<version>${birtVersion}</version>
</dependency>
<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>chartengineapi</artifactId>
<version>${birtVersion}</version>
</dependency>
where ${birtVersion} = 2.6.2
here is a link to the official example of the 2.6.2 release of birt about RadarChart : Radar chart official release example
Can somebody help me ? I really can't believe I didn't found out how to do this in a 3days google search session : that not serious! ... given its popularity and its power, I think they should have invested more effort in the documentation ...
#Birt guyz (if any) > sorry to be so dramatic guys, but I really think that the doc side really sucks ... I hope to be able to help you on this (really, I do)

EDIT + SOLUTION
Sorry for the delay : I should have posted this answer earlier to mark this question as solved.
Just use the RCP report designer to create your report document. Copy ReportEngine/lib/*jars to your /WEB-INF/lib; also create a platform/ directory under WEB-INF/ and copy BIRT ReportEngine configuration/ and plugins/ directories under the newly created WEB-INF/platform/ folder. Now with the *.rptdesign file that you have created in your BIRT RCP designer tool, you will have to use the BIRT API which will allow you to interact with your report...
