I am stuck into this from very long please help me in this. Please let me know how we can
add a Mapinfo file Layer on geotools map please help in this
OGRDataStoreFactory factory = new JniOGRDataStoreFactory();
Map<String, String> connectionParams = new HashMap<String, String>();
connectionParams.put("DriverName", "MapInfo File");
connectionParams.put("DatasourceName",
"C:\\Users\\Varun\\Desktop\\Test\\export\\MS1_Longcall0608143822_001.tab");
DataStore store = factory.createDataStore(connectionParams);
SimpleFeatureSource featureSource = store.getFeatureSource("MS1_Longcall0608143822_001");
MapContent map = new MapContent();
map.setTitle("Quickstart");
Style style = SLD.createSimpleStyle(featureSource.getSchema());
Layer layer = new FeatureLayer(featureSource, style);
map.addLayer(layer); // Now display the map
JMapFrame.showMap(map);

GeoTools is unable to find your GDAL library. There are several things you need to check. From the datastore page:
Your installation of GDAL/OGR needs to be compiled with Java support to use this module.
Is this the case with your install of GDAL?
The OGR DataStore does require the GDAL/OGR native library. Once installed you need to add the location to your PATH on Windows, DYLD_LIBRARY_PATH on Mac, and LD_LIBRARY_PATH on Linux. If you use gt-ogr-bridj and the dll/dylib/so file is not named gdal you will need to set the GDAL_LIBRARY_NAME. Often it is something like gdal10 depending on the version of GDAL you installed. You will also have to set the java.library.path to the GDAL’s location when running your program.
Have you set these environment variables?

I'm using an older version of Quartz.NET (v2.6.2) with .NET Core (or possibly .NET5). I'm getting an error when attempting to use the StdSchedulerFactory.GetScheduler. All my configuration settings are within my appsettings.json where I populate a NameValueCollection with these values and inject them into my classes with DI.
["quartz.scheduler.instanceId"] = "instance_one",
["quartz.threadPool.type"] = "Quartz.Simpl.SimpleThreadPool, Quartz",
["quartz.threadPool.threadCount"] = "5",
["quartz.jobStore.misfireThreshold"] = "60000",
["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz",
["quartz.jobStore.useProperties"] = "false",
["quartz.jobStore.dataSource"] = "default",
["quartz.jobStore.tablePrefix"] = "QRTZ_",
["quartz.dataSource.default.provider"] = "SqlServer-20",
["quartz.dataSource.default.connectionString"] = quartzConn
I am using the StdSchedulerFactory like this, where Settings.Properties is that NameValueCollection which contains all the config settings:
var factory = new StdSchedulerFactory(Settings.Properties);
var scheduler = factory.GetScheduler();
On the GetScheduler method, the error, "Could Not Initialize Datasource: default" is thrown.
The crazy thing is this code works fine in a Framework 4.x project that uses a regular web.config to supply the configuration settings. Also, when I change to use Quartz 3.X with my code above, with configurations in the appsettings.json works fine. Seems that me mixing and matching both versions is causing an issue where Quartz doesn't know how to retrieve some value?
Is there a way to manually build my scheduler and not use the factory?
Thanks!
I've had to go back to Framework 4 and Quartz 2.6 to get them to play nicely together. I can only get Quartz 3.x to work with .NET Core/5. Stepping through the source code with dotPeek, Quartz 2.6 is using ConfigurationManager to pull web.config details that don't exist in Core/5. At this point I don't remember if I tried to add my own web.config file to this project or not, but I've since moved on.
My Liferay 7 server was using SomeModule happily, until I deployed a new version of SomeModule which has an additional required field favoriteColor.
Now whenever I try to load the portlet Liferay says:
java.lang.RuntimeException: Unable to create snapshot class for interface some.SomeModuleConfiguration
at com.liferay.portal.configuration.metatype.bnd.util.ConfigurableUtil._createConfigurableSnapshot(ConfigurableUtil.java:77)
at com.liferay.portal.configuration.metatype.bnd.util.ConfigurableUtil.createConfigurable(ConfigurableUtil.java:51)
at some.SomeModule.activate(SomeModule.java:50)
...
aused by: java.lang.IllegalStateException: Attribute is required but not set favoriteColor
at aQute.bnd.annotation.metatype.Configurable$ConfigurableHandler.invoke(Configurable.java:75)
at com.sun.proxy.$Proxy1220.favoriteColor(Unknown Source)
at some.SomeModuleConfigurationSnapshot407.<init>(Unknown Source)
The configuration UI for SomeModule does not show anything about favoriteColor.
How to fix that, for instance by setting favoriteColor to its default value?
An alternative path would be using a OSGi configuration file to set defaults and missing values. You can use those files as you do for those modules that come with liferay; e.g., elasticsearch config. (check your osgi/configs directory)
If you are lucky enough to have the source code of the module, you can solve this problem like this:
Temporarily make the new field optional, but replacing required = true to required = false in SomeModuleConfiguration.java.
Deploy the module.
Load the configuration page, save.
Restore to required = true.
Deploy again.
Alternative answers welcome!
Frameworks like Spring, Struts facilitates for property file reading. For instance MessageResources in Struts. I want to know whether there are such property files which are in built supported by Restlet framework itself. If there is one, then I will not need to re invent the wheel and be able to use it straight.My application configuration values will be included in that file. I am new to Restlet, I couldn't find any soulution. Any way to do this?
There is no support like this in Restlet. That said you can leverage client protocols to load these properties files from difference locations:
Protocol.FILE - from filesystem directly
Protocol.CLAP - from classpath
Protocol.OBAP - from OSGi bundle
Here is a sample:
ClientResource cr = new ClientResource("clap://someproperties.properties");
Properties props = new Properties();
props.load(cr.get().getStream());
You need to specify this protocol when defining your component:
Component component = new Component();
(...)
component.getServers().add(Protocol.HTTP, 8182);
component.getClients().add(Protocol.CLAP);
I build a simple weka application using Weka 3.7.13 dev version using MAVEN. I have initialise the pom.xml function to get weka library from the repository.
i want to run a simple clustering algorithm using weka, and connecting it to MySQL database. As per documentation, the weka need to have a DatabaseUtil.props file which contains it's jdbc driver. I have setup that.
This is my project structure:
I can retrieve the DatabaseUtils.props using my code below. But somehow the weka itself cannot recognise the jdbc:Url and driver name which i already configure inside.
DatabaseUtil.props file:
# JDBC driver (comma-separated list)
jdbcDriver=com.mysql.jdbc.Driver
# database URL
jdbcURL=jdbc:mysql://127.0.0.1:3306/datamining
Java code which i trigger the Weka module:
public void dm(){
int cluster = 4;
InstanceQuery clusterQuery = null;
try{
//file reader of database utilities properties
ClassLoader classLoader = getClass().getClassLoader();
File fileProps = new File(classLoader.getResource("DatabaseUtils.props").getFile());
//setup the data preparation functionality then connect to database
clusterQuery = new InstanceQuery();
clusterQuery.setUsername("test");
clusterQuery.setPassword("test");
clusterQuery.setQuery("SELECT * FROM TEMP_KMEANS");
clusterQuery.setCustomPropsFile(fileProps);
But when executed the function returning error: java.sql.SQLException: No suitable driver found for jdbc:idb=experiments.prp
It seems that the DatabaseUtils.props file cannot override the default driver value jdbc:idb=experiments.prp
Any ideas why this is throwing?
Any feedback and answer much appreciated.
I created a DatabaseUtils.props file in the src / main / resources folder and wrote the following code. It worked for me, I'm using weka 3.8.0.
File file = new File(getClass().getClassLoader().getResource("DatabaseUtils.props").toURI());
InstanceQuery query = new InstanceQuery();
query.setCustomPropsFile(file);
query.setUsername(MYSQL_USER);
query.setPassword(MYSQL_PASSWORD);
query.setQuery("select * from Action");
instances = query.retrieveInstances();
System.out.println(instances.toString());
The documentation says "These may be changed by creating a java properties file called DatabaseUtils.props in user.home or the current directory". Your properties file does not match those requirements (a properties file in a jar is not on the filesystem). See also Chapter 14 of the Weka manual.
An alternative solution is to set the URL in code using setDatabaseURL. As long as the JDBC driver is on the classpath this should work.
In my windows store app using the Visual Studio 2012 designer I want to be able to load some model objects for the designer. I've done this plenty of times before where I supply a xaml file using the ms-appx:/// uri without error. However, for this project I need to be able to instantiate a class and have it convert raw xml of a different format into my model objects.
I'm using the following xaml to instantiate my class for the designer:
d:DataContext="{Binding Source={d:DesignInstance Type=model:Walkthroughs, IsDesignTimeCreatable=True}}"
In my Walkthroughs class had code that did this initially:
public Walkthroughs()
{
if (Windows.ApplicationModel.DesignMode.DesignModeEnabled)
AppDataLoader.LoadWalkthroughs(this, XDocument.Load("ms-appx:///SampleData/walkthroughs.xml"));
}
I first ran into an issue where the XDocument.Load did not understand the ms-appx:/// uri so I modified my code to something very simplistic:
AppDataLoader.LoadWalkthroughs(this, XDocument.Load(#"C:\walkthroughs.xml"));
Now I get access to path '' is denied.
I've tried several directories as well to no avail. I'm even running Visual Studio as an Administrator. If I remove the prefix altogether I get the following error:
Could not find file 'C:\Users\{me}\AppData\Local\Microsoft\VisualStudio\11.0\Designer\ShadowCache\omxyijbu.m4y\yofsmg1x.avh\walkthroughs.xml'.
Has anyone been able to load files from the file system when the designer instantiates objects?
Thanks,
-jeff
XDocument.Load(string uri) seems to have problems with loading Project resources from ms-appx:/
Regarding your second approach: Direct access to "C:" is not permitted. Ther is only a handful of special folders that you can access. Check out my workaround for this (my xml file is within the Assets folder of my project:
var storageFolder = Windows.ApplicationModel.Package.Current.InstalledLocation;
storageFolder = await storageFolder.GetFolderAsync("Assets");
var xmlFile = await storageFolder.GetFileAsync("data.xml");
var stream = await xmlFile.OpenReadAsync();
var rdr = new StreamReader(stream.AsStream(), System.Text.Encoding.GetEncoding("ISO-8859-1")); //needed if you have "ä,ß..." in your xml file
var doc = XDocument.Load(rdr);
