In Eclipse I have an error on my top blank line and I cant get rid of it. Here's my code (I am making a bukkit plugin):
//this is where I get the error
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin {
#Override
public void onEnable() {
new EventHandler(this);
}
#Override
public void onDisable() {
}
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (cmd.getName().equalsIgnoreCase("BLANK") && sender instanceof Player) {
Player player = (Player) sender;
return true;
}
return false;
}
}
I can't find anyway around it. Please help.
You appear to be missing your package name. Try this instead:
package my.package.name;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin {
#Override
public void onEnable() {
new EventHandler(this);
}
#Override
public void onDisable() {
}
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (cmd.getName().equalsIgnoreCase("BLANK") && sender instanceof Player) {
Player player = (Player) sender;
return true;
}
return false;
}
}
Remember to replace my.package.name with your package name.

make your variable static and define it before onCreate() method use that variable in another activity by call like this.
YourMainActivity.yourstaticvariable
how do I get the text of a selected tab in GWT? I see there is a method com.google.gwt.user.client.ui.TabBar.setTabText(String text) but how do I get the text?
I ended up extending TabPanel like so:
package com.benhowden.gwttemplate;
import com.google.gwt.user.client.ui.TabPanel;
import com.google.gwt.user.client.ui.Widget;
import java.util.ArrayList;
import java.util.List;
public class DFSTabPanel extends TabPanel {
List<String> tabsTexts;
public DFSTabPanel() {
super();
tabsTexts = new ArrayList<String>();
}
#Override
public void add(Widget w, String tabText) {
super.add(w, tabText);
tabsTexts.add(tabText);
}
#Override
public boolean remove(int index) {
boolean removed = super.remove(index);
if(removed) {
tabsTexts.remove(index);
return removed;
}
return removed;
}
#Override
public void clear() {
super.clear();
tabsTexts.clear();
}
public String getTabText(int index) {
return tabsTexts.get(index);
}
}
I've been struggling with passing Java objects from Java through JSNI (gwt-exporter generated) into Java and wonder if anybody can help?
I am creating an object in Java ("Person"), passing it to a JSNI method ("displayPerson") that invokes a Java method exposed with gwt-exporter ("CommonService.displayPerson"); however the parameter to the last stage becomes null.
If I pass a String it works OK; it's just with my objects I hit the problem.
Person is defined in a GWT application JAR inherited by the other GWT application.
Thanks for looking,
Mike
GWT application
package com.anstis.pluginserver.client;
import com.anstis.plugincommon.shared.Person;

GWT.create(CommonService.class);
onLoadImpl();
RootPanel.get("container").add(getButton());
}
private native void onLoadImpl() /*-{
if ($wnd.jscOnLoad && typeof $wnd.jscOnLoad == 'function') $wnd.jscOnLoad();
}-*/;
private Button getButton() {
Button btn = new Button("Click!");
btn.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
Person p = new Person();
p.setName("Smurf");
p.setAge(500);
displayPerson(p);
}
});
return btn;
}
private native void displayPerson(Person person) /*-{
// The below displays shows 'person' is not null
alert("PluginServer.displayPerson.person is " + (person != null ? "not " : "") + "null");
try {
var pluginServer = new $wnd.com.anstis.pluginserver.CommonService();
// The below displays shows 'pluginServer' is not null
alert("PluginServer.displayPerson.pluginServer = " + pluginServer);
pluginServer.displayPerson(person);
} catch(err) {
alert(err);
}
}-*/;
}
CommonService.java
package com.anstis.pluginserver.client;
import org.timepedia.exporter.client.Export;
import org.timepedia.exporter.client.Exportable;
import com.anstis.plugincommon.shared.Person;
import com.anstis.plugincommon.shared.PluginCallback;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.Window;
#Export
public class CommonService implements Exportable {
public void displayPerson(Person person) {
//The below shows 'person' *IS* null
Window.alert("CommonService.displayPerson.person is "
+ (person != null ? "not " : "") + "null");
Window.alert("Name=" + person.getName());
}
}
Person.java
package com.anstis.plugincommon.shared;
import org.timepedia.exporter.client.Exportable;
public class Person implements Exportable {
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
You need no to implement Exportable for Person class.
public class Person {
and it works.
If anybody else stumbles across this question, I now have a working example at git://github.com/manstis/gwt-plugins.git
