I have recently migrated my environment from Java 6 to Java 7. Installed Netbeans 8.0.2. A Grails(Version 2.1.1) project is running in it.
From Grails project using withREST a web service is called in another Tomcat (Version 8). This tomcat(version 8) is using axis2 to expose the methods. A java class "OneWebservice.java". Built as aar file and deployed.
Code is like this.
import com.project.Two.TwoFunction;
import com.project.Three.ThreeFunction;
public class OneWebservice{
function getOneandTwo()
{
com.project.Two.TwoFunction();
.....
com.project.Three.ThreeFunction();
}
}
When function getOneandTwo() is called, in the above code Two.TwoFunction is called, while Three.ThreeFunction is not called. No error is also printed.
Ok, Got this fixed.
We have Solr implemented for text based search.
Import related to Solr was there in com.project.Three.ThreeFunction this class file
import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.response.QueryResponse;
import org.apache.solr.common.SolrDocument;
import org.apache.solr.common.SolrDocumentList;
was giving problem, if this is commented its working fine...
I think Solr is not working in Java 8 and Tomcat 8

I am using latest dependency of Apache POI 4.1.2 in my java application together with Tika.
I realized that the class ImageHeaderPNG is missing with the following calls tack:

According to the online documentation it should be available:

Using grails 2.3.2, Java 1.6.0_65, trying to compile the following placed in the services directory. Even if it is not a service, and just put in the src/groovy directory, it still causes the same compile error.
I installed groovy 2.1.9 (and tried 2.2.0) which appears to be the version used by grails 2.3.2 and ran groovyc -cp quava-13.0.1.jar TestCache.groovy and it worked fine. So it appears to be something related to grails.
package somewhere
import com.google.common.cache.Cache
import groovy.transform.CompileStatic
#CompileStatic
class TestCacheService {
private final Cache<URL, String> cache
TestCacheService() {
cache = null
}
}
I receive the following error:

Is this a known bug?
Any workaround?
Google's Cache class uses the Nullable annotation. I had multiple nullable annotation implementations on my classpath. I think removing 'edu.washington.cs.types.checker:checker-framework:1.6.4' from the classpath solved this problem.
I´m currently running Grails 2.3.0 and Java jdk1.7.0_40 on a Windows 7 machine, no IDE. I wanted to see how the new Rest functionality looks like. So I created the domain class as follows:
package fergara
import grails.rest.*
#Resource(uri='/Cars', formats=['json', 'xml'])
class Car {
String model
static constraints = {
}
}
The error I got when open the url:
URI
/FergaraTest/Cars/1 Class
org.codehaus.groovy.runtime.typehandling.GroovyCastException
Message
Cannot cast object 'fergara.CarController#12c43f7' with class 'fergara.CarController' to class 'org.codehaus.groovy.grails.plugins.web.api.CommonWebApi'
I feel that the Oracle´s Java SDK is the problem. To make the app run I have to pass "no-reloading" to the grails run-app command, otherwise I get an error saying that it could not start the VM and cannot open the springloaded-core-1.1.3.jar.
A have the Grails 2.3.0 installed on an Ubuntu 13.04 with OpenJDK6 and it is working good.
Hope someone can shed a light on this. Thank you.
I am migrating an old JSF application from WAS 6.x to WAS 8.x and I am getting the following compilation error:
The import com.ibm.faces cannot be resolved
This comes from the following code:
import com.ibm.faces.component.html.HtmlScriptCollector;
...
protected HtmlScriptCollector onLoadCollector;
How do I port this for use on WAS 8.x?
Looks so far like these methods can just be removed. A better explanation will get the check.
package com.scheduler.process;
public class Process {
public enum state {
NOT_SUBMITTED, SUBMITTED, BLOCKED, READY, RUNNING, COMPLETED
}
private state currentState;
public state getCurrentState() {
return currentState;
}
public void setCurrentState(state currentState) {
this.currentState = currentState;
}
}
package com.scheduler.machine;
import com.scheduler.process.Process;
import com.scheduler.process.Process.state;
public class Machine {
com.scheduler.process.Process p = new com.scheduler.process.Process();
state s = state.READY; //fails if I don't also explicitly import Process.state
p.setCurrentState(s); //says I need a declarator id after 's'... this is wrong.
p.setCurrentState(state.READY);
}
Modified the example to try and direct to the issue. I cannot change the state on this code. Eclipse suggests importing Process.state like I had on my previous example, but this doesn't work either. This allows state s = state.READY but the call to p.setCurrentState(s); fails as does p.setCurrentState(state.READY);
Problem continued.... Following Oleg's suggestions I tried more permutations:
package com.scheduler.machine;
import com.scheduler.process.Process;
import com.scheduler.process.Process.*;
public class Machine {
com.scheduler.process.Process p = new com.scheduler.process.Process();
public state s = Process.state.READY;
p.setCurrentState(s);
p.setCurrentState(state.READY);
}
Okay. It's clear now that I'm a candidate for lobotomy.
package com.scheduler.machine;
import com.scheduler.process.Process;
import com.scheduler.process.Process.state;
public class Machine {
public void doStuff(){
com.scheduler.process.Process p = new com.scheduler.process.Process();
state s = state.READY; //fails if I don't also explicitly import Process.state
p.setCurrentState(s); //says I need a declarator id after 's'... this is wrong.
p.setCurrentState(state.READY);
}
}
I needed to have a method in the class--but we're still missing something (probably obvious) here. When I go via the command line and run javac on the Machine class AFTER compiling Process, I still get the following error:
mseil#context:/media/MULTIMEDIA/Scratch/Scratch/src/com/scheduler/machine$ javac Machine.java
Machine.java:3: package com.scheduler.process does not exist
import com.scheduler.process.Process;
^
So I guess the question now becomes, what idiot thing am I missing that is preventing me from compiling this by hand that eclipse is doing for me behind the scene?
======
Problem solved here:
Java generics code compiles in eclipse but not in command line
This has just worked for me:
Download latest Eclipse
Create new project
Create two packages com.scheduler.process and com.scheduler.machine
Create class Process in package com.scheduler.process and class Machine in com.scheduler.machine and copy their contents from your post modifying them to conform to Java language syntax, like this:
Everything compiles right away.
------ to answer the previous version of the question ------
To answer the question as it is right now: you need to either
import com.scheduler.process.Process.status or import com.scheduler.process.Process.* and refer to status as just status
or
import com.scheduler.process.* or import com.scheduler.process.Process and refer to status as Process.status
------ to answer the original version of the question ------
You can't import classes that are not inside some package. You just can't. It is a compile time error to import a type from the unnamed package.
You don't need to import anything if your classes are in the same package, or if all of your classes are packageless.
If Process class was inside some package it would be possible to import just its status inner class: import a.b.c.Process.status would work just fine.
All your Windows/Linux migration issues don't have anything to do with Java and exceptions that you see. import Process.state; will produce exception on any OS because you can't import classes that don't belong to any package.
Eclipse doesn't use the Sun JDK by default. I would assume that you are using Eclipse's built in compiler as Sun's JDK and the OpenJDK are almost identical.
Java code compiles and runs exact the same on Windows and Linux most of the time (unless you use a few of the platform specific operations)
I suspect you are not building the code the same way and when you compile Machine, the Process class has not been compiled.
I suggest you use a standard build system like maven or ant and it will build the same everywhere. Failing that run Eclipse on Linux or just the same .class you use on windows as they don't need to be re-compiled in any case.
BTW: You don't need to import Process.state as it not used and its in the same package (so you wouldn't need to if you did)
