I`ve got simple validation like:
#Column(length=6)
#Pattern(regexp = "[0-9]{2}( |-)?[0-9]{3}", message = Errors.kod_pocztowy)
private String kod_pocztowy;
But it return strange errors:

When i`m changing message property to text like:
#Column(length=6)
#Pattern(regexp = "[0-9]{2}( |-)?[0-9]{3}", message = "Now its ok")
private String kod_pocztowy;
Then everything seems to be ok. What`s the problem ? Anyone can explain it for me?
Ok, i`ve found it by myself. Using chars like {} causes Ebean to load message from class and this message is related to that class.

This question already has answers here:
Why does a Try/Catch block create new variable scope?
(5 answers)
Closed 6 years ago.
I wasn't able to get apache commons cli to work.
apache commons-cli
I have the most simple start:
This is the only class.
Resources are added with maven(commandline).
import org.apache.commons.cli.*;
public class App {
public static void main(String[] args) {
// create Options object
Options options = new Options();
CommandLineParser parser = new DefaultParser();
// add t option
options.addOption("t", false, "display current time");
try{
CommandLine cmd = parser.parse( options, args);
}catch(ParseExeption ex){
}
if(cmd.hasOption("t")) {
// print the date and time
}else {
// print the date
}
}
}
No matter what I tried. I get the "cannot find symbol".
This is the last part of the error:

thank you.
Simply replace ParseExeption with ParseExceptionand move the if/else block in the same code block as where you defined your variable cmd otherwise it won't be visible, for example as next:
public static void main(String[] args) throws ParseException{
// create Options object
Options options = new Options();
CommandLineParser parser = new DefaultParser();
// add t option
options.addOption("t", false, "display current time");
CommandLine cmd = parser.parse( options, args);
if(cmd.hasOption("t")) {
// print the date and time
}else {
// print the date
}
}
In my current project, i have this code:
for(Annotation annotation : field.getAnnotations()) {
String package = annotation.annotationType().getPackage().getName();
if(package.equals("com.loja.annotations.input_type"))
input.setAttribute("type", annotation.annotationType().getSimpleName());
}
when i try build the project, this code causes a compilation failure due to this error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project store: Compilation failure: Compilation failure:

[ERROR] /c:/Users/Kleber Mota/Documents/GitHub/app/src/main/java/com/loja/thymeleaf/processor/form/InputProcessor.java:[38,22] variable declaration not allowed here
anyone can see what's wrong here?
line 37 is: String package = annotation.annotationType().getPackage().getName(); and line 38 is if(package.equals("com.loja.annotations.input_type"))
you can try this..
annotation.annotationType().getName();
You can print out your "package" variable after line 37 (before if).
I wrote and ran the similar code and it worked for me. I created a custom annotation in my api package and line 37 returned "api".
How can I do some db operation on playframework global class method on start.
I would like to put some data to db from other source.
For now I have:
My code:
public class Global extends GlobalSettings {
#Override
#Transactional
public void onStart(Application application) {
Akka.system().scheduler().schedule(
Duration.create(1, TimeUnit.SECONDS), // start task delay
Duration.create(24, TimeUnit.HOURS), // between task instance delay
//Duration.create(24, TimeUnit.HOURS), // between task instance delay
new Runnable() {
#Override
#Transactional
public void run() {
System.out.println("Importing CRM data...");
ImportCrmData.start();
System.out.println("... imported");
}
},
Akka.system().dispatcher()
);
I am getting an error:

I use playframework 2.2.4 with java

Afted adding:

});
I am getting error.

Finally I've added:
public void run() {
JPA.withTransaction(
ImportCrmData.start()
);
}
Remove #Transactional annotations, they are useful only in controllers. Wrap CRM import with JPA.withTransaction method. Java 8 syntax:
JPA.withTransaction(() -> {
ImportCrmData.start();
});
And non Java 8 syntax:
JPA.withTransaction(new Callback0() {
#Override
public void invoke() throws Throwable {
ImportCrmData.start();
}
});

I think maven use wrong slf4j logger in this case.
But, I really don't know how to fix this.
Anyone can help? thanks!
Consider opening an issue at https://github.com/mpercy/flume-load-gen/issues because it is free software.
I have added the simple code write to a file into an open source project (Saiku) that before my changes builds and compiles cleanly.
The program compiles cleanly in Centos 5.3 Eclipse (no red X's).
However, when rerunning the maven build script, the compiler errors are generated (Exhibit 1):
Does Maven compile java projects differently from Eclipse?

The code that you have added is not within a method/constructor/block etc. This is not valid Java, and thus does not compile.
You need to surround this with something like follows:
public void doSomething
{
// Insert code here
}
Alternatively, you can place it in an existing method, or constructor, depending on when you need this code to execute.
Why Eclipse is not highlighting this error is beyond me. It would normally report this. Try refreshing your project or cleaning/rebuilding and you should see that it will fail to compile.
