I'm trying to get a connection to jira's default database (HSQL) using the following java code:
InitialContext initalContext = new InitialContext();
Context context = (Context) initalContext.lookup("java:comp/env");
dataSource = (DataSource) context.lookup("jdbc/JiraDS");
I have added catalina.jar, naming-factory.jar, naming-java.jar and tomcat-juli.jar as per the answer given in stack overflow.
However, I'm still getting an error:
javax.naming.NoInitialContextException: Cannot instantiate class: org.apache.naming.java.javaURLContextFactory [Root exception is java.lang.ClassNotFoundException: org.apache.naming.java.javaURLContextFactory]
at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.init(Unknown Source)
at javax.naming.InitialContext.<init>(Unknown Source)
at in.componence.jira.plugin.util.JiraDataSourceUtil.getConnectionToJiraDB(JiraDataSourceUtil.java:40)
Please help me out.
The Classloader does not see org.apache.naming.java.javaURLContextFactory. Which jar-file contains the binary of the class? It has to be on the classpath. May be there are multiple classloaders present abd the moaning one is not the one in your focus?

We are running Micronaut with Thymeleaf views and the Layout dialect (we add it manually by overriding Micronaut's ThymeleafFactory). Below are the dependencies (Micronaut version is 3.2.7):
implementation 'io.micronaut.views:micronaut-views-core:3.1.2'
implementation 'io.micronaut.views:micronaut-views-thymeleaf:3.1.2'
implementation 'nz.net.ultraq.thymeleaf:thymeleaf-layout-dialect:3.0.0'
The problematic code is this:
<html layout:decorate="~{/layout-top}">
This seems to work fine when running with ./gradlew run, but crashes when running from a fat (shadow) jar using java -jar .... This would point to classpath issues, but we couldn't figure out what would those be.
Below the error message when running the shadow jar:
Caused by: groovy.lang.MissingMethodException: No signature of method: io.micronaut.views.thymeleaf.WebEngineContext.getOrCreate() is applicable for argument types: (String, nz.net.ultraq.thymeleaf.layoutdialect.context.extensions.IContextExtensions$_getPrefixForDialect_closure1) values: [DialectPrefix::org.thymeleaf.standard.StandardDialect, nz.net.ultraq.thymeleaf.layoutdialect.context.extensions.IContextExtensions$_getPrefixForDialect_closure1#26b0c4d0]

We debugged this and isolated the failing code in nz.net.ultraq.thymeleaf.layoutdialect.context.extensions.IContextExtensions:
static String getPrefixForDialect(IContext self, Class<IProcessorDialect> dialectClass) {
return self.getOrCreate(DIALECT_PREFIX_PREFIX + dialectClass.name) { ->
def dialectConfiguration = self.configuration.dialectConfigurations.find { dialectConfig ->
return dialectClass.isInstance(dialectConfig.dialect)
}
return dialectConfiguration?.prefixSpecified ?
dialectConfiguration?.prefix :
dialectConfiguration?.dialect?.prefix
}
}
It seems that the IContext argument is not what's supposed to be, but we couldn't really find the root cause for this. Nor why this is behaving differently with the two different methods of running the same code.
Upon further investigation, we discovered that this is related to this bug in the shadow jar plugin: https://github.com/johnrengelman/shadow/issues/490
The library thymeleaf-layout-dialect is using a nz.net.ultraq.extensions:groovy-extensions:1.1.0
which, in turn, registers some Groovy extensions through META-INF/services/org.codehaus.groovy.runtime.ExtensionModule
The shadow jar plugin doesn't handle these correctly (it only handles META-INF/groovy/... paths).
As per ticket comments here https://github.com/johnrengelman/shadow/issues/490 , there is a workaround, but it's deeply unpleasant.

What's wrong? How can I fix this?
AbstractGenerator calls VelocityGenerator(false) which sets the field log to false.
The code in initVelocity() will then create an instance of org.slf4j.helpers.NOPLogger (if it can) and put that into the Properties instance.
Eventually, org.apache.commons.collections.ExtendedProperties.convertProperties(Properties) will be called. This line
c.setProperty(s, props.getProperty(s));
results in call to Hashtable.put(s, null) because Properties.getProperty() will return null for non-String elements in the map like the NOPLogger instance.
The culprit is that you have two implementations of Velocity on the classpath. One has version 1.x with the coordinate org.apache.velocity:velocity and one org.apache.velocity:velocity-engine-core with version 2.2.
Exclude the dependency to Velocity 1.x to fix this error. Velocity 2.x uses ExtProperties instead of ExtendedProperties which contains a patch for this bug.
I am trying to register for a servlet the following and getting an exception. The code is:
static {
IIORegistry registry = IIORegistry.getDefaultInstance();
registry.registerServiceProvider(new com.twelvemonkeys.servlet.image.IIOProviderContextListener());
registry.registerServiceProvider(new com.twelvemonkeys.imageio.plugins.jpeg.JPEGImageReaderSpi());
registry.registerServiceProvider(new com.twelvemonkeys.imageio.plugins.jpeg.JPEGImageWriterSpi());
}
I am getting the following exception thrown. Funny thing is I only am using the read not the write.
I am using the 3.6 version of twelvemonkeys.
Thanks for any hints!

Ok, I solved the problem. I went to https://github.com/haraldk/TwelveMonkeys#manual-dependency-example and I re-downloaded all the jars mentioned in the article making sure I paid close attention to the versions to make sure 3.6 was selected since 3.6 is not shown as part of the jar name (which I liked). Once I restarted eclipse I got past that problem.
Many thanks haraldK!

there seems to be a need to provide a properties file. Is correct?
*Edited to answer to Michael Hunger:
Well .. I changed the version of blueprints, now is 2.5.0-SNAPSHOT, but nothing changed. So i provided the configs using the map ask asked by the constructor
Map<String, String> configurazione = new HashMap<String, String>();
configurazione.put("neostore.propertystore.db.strings.mapped_memory", "250M");
configurazione.put("neostore.propertystore.db.arrays.mapped_memory", "100M");
configurazione.put("neostore.relationshipstore.db.mapped_memory", "3845M");
configurazione.put("neostore.nodestore.db.mapped_memory", "350M");
configurazione.put("neostore.propertystore.db.mapped_memory", "350M");
configurazione.put("neostore.nodestore.db.mapped_memory", "769M");
Neo4j2Graph grafo = new Neo4j2Graph("/Users/pipe/Dev/neo4j-community-2.1.0-M01/data/graph.db", configurazione);
Now the exception is changed, and i really don't know what is wrong.. I linked in paste bin to report the complete stack.
http://pastebin.com/XpipSysp
at last a NoSuchMethodError is thrown. What am I missing?
Thanks a lot.
Which blueprints version are you using?
Blueprints 2.5-SNAPSHOT is compatible with Neo4j 2.0.0.
Please note there is a separate module for Neo4j 2.0 called blueprints-neo4j2
And the classes are called Neo4j2Graph Neo4j2Vertex etc.
You should also be able to provide config to the Neo4j2Graph.
