Have you added Internet permission to your manifest:
<uses-permission android:name="android.permission.INTERNET"/>

The error was being thrown because of an error in the URL. The URL needed my IP address to function properly rather than the URL i was providing because that the webservice was not able to understand.

Depending on what KSOAP2 version you are using error may vary.
Its recommend that use KSOAP2 v3+ lib.
Simply use following code to override...
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
and also use...

How to save the current state of switches in Android Studio?

I know very little about programming. I downloaded Android Studio and started tinkering with it. I tried to make the app that they put on the tutorial and it worked. However I tried to add more functionality to it and I've failed so far. Excuse me if you see unnecessary junk on my code, I'm just kinda trying everything at first and I do feel a little misguided.
Anyways, onto the question. I have a Switch (id:toggle_text) with an OnClick action (change_font). When the switch is toggled it should change the font size of a different activity through intent1. Currently not only does it not send the font size variable (the variable keeps the default value you put on getIntExtra), but now that I tried to add the ability to save the current state it just shows errors. Here's the code:
package com.example.myfirstapp;
import android.content.Intent;
import android.content.SharedPreferences;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.ToggleButton;
import android.widget.TextView;
import static com.example.myfirstapp.R.id.toggle_text;
import static com.example.myfirstapp.R.string.change_font;
public class ShowAnOption extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_an_option);
SharedPreferences sharedPrefs = getSharedPreferences("com.example.xyz", MODE_PRIVATE);
toggle.setChecked(sharedPrefs.getBoolean("NameOfThingToSave", true));
}
public void change_font(View v) {
int fssize;
if (toggle.isChecked())
{
SharedPreferences.Editor editor = getSharedPreferences("com.example.xyz", MODE_PRIVATE).edit();
editor.putBoolean("NameOfThingToSave", true);
editor.commit();
fssize=20;
}
else
{
SharedPreferences.Editor editor = getSharedPreferences("com.example.xyz", MODE_PRIVATE).edit();
editor.putBoolean("NameOfThingToSave", false);
editor.commit();
fssize=40;
}
Intent intent1 = new Intent (getBaseContext(), DisplayMessageActivity.class);
intent1.putExtra("Font_Size", fssize);
}
}
It says "cannot resolve symbol toggle" on toggle.setChecked() and the if statement. What can I do to fix this? Also, why does it not get sent to the other activity? Here's the code on the other activity:
package com.example.myfirstapp;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.ViewGroup;
import android.widget.TextView;
public class DisplayMessageActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_message);
Intent intent = getIntent();
Intent intent1 = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
int Font_Size = intent1.getIntExtra("Font_Size",50);
TextView textView = new TextView(this);
textView.setTextSize(Font_Size);
textView.setText(message);
ViewGroup layout = (ViewGroup) findViewById(R.id.activity_display_message);
layout.addView(textView);
}
}
Thanks and sorry for the long read. If there's anything else that needs to be known let me know and I'll gladly show.
We did not try to change the font size but here is how to use the switch widget.
Our design is two activities MainActivity and SwitchActivity we changed a CheckBox from unchecked to checked The switch is on the MainActivity code below
setOnCheckedChangeListener();
private void setOnCheckedChangeListener() {
swAll.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
Toast.makeText(MainActivity.this, "Switch On", Toast.LENGTH_SHORT).show();
Intent intentSP = new Intent(MainActivity.this, SwitchActivity.class );
Bundle extras = new Bundle();
extras.putString("FONT","true" );
intentSP.putExtras(extras);
startActivity( intentSP );
} else {
Toast.makeText(MainActivity.this, "Switch Off", Toast.LENGTH_SHORT).show();
}
}
});
}
Now in the SwitchAcvity we capture the value from the intent and fire the method
doWhat()
Intent intentSP = getIntent();
Bundle bundle = intentSP.getExtras();
tORf = bundle.getString("FONT");
doWhat(null);
And here is the doWhat method
public void doWhat(View view){
if(tORf.equals("true")){
chkBoxOne.setChecked(true);
}else {
Toast.makeText( SwitchActivity.this, "NOT TRUE", Toast.LENGTH_LONG ).show();
}
}

Getting user data in NewProjectCreationPage in Eclipse Plugin

I have been successful in making a plugin. However now i need that on project creation page i add some more textboxes to get the user information. Also i need to use this information to add into the auto generated .php files made in project directory.
I want to know how can i override the WizardNewProjectCreationPage to add some more textboxes to the already given layout. I am pretty new to plugin development. Here is the code for my custom wizard.
import java.net.URI;
import org.eclipse.core.runtime.CoreException;
import org.eclipse.core.runtime.IConfigurationElement;
import org.eclipse.core.runtime.IExecutableExtension;
import org.eclipse.jface.viewers.IStructuredSelection;
import org.eclipse.jface.wizard.Wizard;
import org.eclipse.jface.wizard.WizardDialog;
import org.eclipse.ui.INewWizard;
import org.eclipse.ui.IWorkbench;
import org.eclipse.ui.dialogs.WizardNewProjectCreationPage;
import org.eclipse.ui.wizards.newresource.BasicNewProjectResourceWizard;
import rudraxplugin.pages.MyPageOne;
import rudraxplugin.projects.RudraxSupport;
public class CustomProjectNewWizard extends Wizard implements INewWizard, IExecutableExtension {
private WizardNewProjectCreationPage _pageOne;
protected MyPageOne one;
private IConfigurationElement _configurationElement;
public CustomProjectNewWizard() {
// TODO Auto-generated constructor stub
setWindowTitle("RudraX");
}
#Override
public void init(IWorkbench workbench, IStructuredSelection selection) {
// TODO Auto-generated method stub
}
#Override
public void addPages() {
super.addPages();
_pageOne = new WizardNewProjectCreationPage("From Scratch Project Wizard");
_pageOne.setTitle("From Scratch Project");
_pageOne.setDescription("Create something from scratch.");
addPage(one);
addPage(_pageOne);
}
#Override
public boolean performFinish() {
String name = _pageOne.getProjectName();
URI location = null;
if (!_pageOne.useDefaults()) {
location = _pageOne.getLocationURI();
System.err.println("location: " + location.toString()); //$NON-NLS-1$
} // else location == null
RudraxSupport.createProject(name, location);
// Add this
BasicNewProjectResourceWizard.updatePerspective(_configurationElement);
return true;
}
#Override
public void setInitializationData(IConfigurationElement config,
String propertyName, Object data) throws CoreException {
_configurationElement = config;
// TODO Auto-generated method stub
}
}
Ask for any other code required. Any help is appreciated. Thank You.
Instead of using WizardNewProjectCreationPage directly create a new class extending WizardNewProjectCreationPage and override the createControl method to create new controls:
class MyNewProjectCreationPage extends WizardNewProjectCreationPage
{
#Override
public void createControl(Composite parent)
{
super.createControl(parent);
Composite body = (Composite)getControl();
... create new controls here
}
}

Reading xls file in gwt

I am looking to read xls file using the gwt RPC and when I am using the code which excecuted fine in normal file it is unable to load the file and giving me null pointer exception.
Following is the code

else
{
try

sheet = workbook.getSheetAt(sheetindex);
}
catch (Exception ex)
{
logger.error(ex.getMessage());
}
}
}// end loadxlsxFile

while(cellIter.hasNext())
{
cell = (XSSFCell) cellIter.next();
NO_OF_Column++;
}
return NO_OF_Column+"";
}
}
}
I am calling it in client program by this code:
final AsyncCallback<String> callback1 = new AsyncCallback<String>() {
public void onSuccess(String result) {
RootPanel.get().add(new Label("In success"));
if(result==null)
{
RootPanel.get().add(new Label("result is null"));
}
RootPanel.get().add(new Label("result is"+result));
}
public void onFailure(Throwable caught) {
RootPanel.get().add(new Label("In Failure"+caught));
}
};
try{
getService().getNumberOfColumns(callback1);
}catch(Exception e){}
}
Pls tell me how can I resolve this issue as the code runs fine when run through the normal java file.
Why are using using the system classloader, rather than the normal one?
But, If you still want to use then look at this..
As you are using like a web application. In that case, you need to use the ClassLoader which is obtained as follows:
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
This one has access to the all classpath paths tied to the webapplication in question and you're not anymore dependent on which parent classloader (a webapp has more than one!) has loaded your class.
Then, on this classloader, you need to just call getResourceAsStream() to get a classpath resource as stream, not the getSystemResourceAsStream() which is dependent on how the webapplication is started. You don't want to be dependent on that as well since you have no control over it at external hosting:
InputStream input = classLoader.getResourceAsStream("filename.extension");
The location of file should in your CLASSPATH.

Control Netbeans from Commandline: attach Debugger from Shell-script

I'm using a daemon-script which is monitoring a remote server. When the remote server is up, i want that Netbeans automatically connects it's Debugger to the remote Server.
Is it possible to control this behavior from commandline?
To type Something like
netbeans --attach-debugger 192.168.178.34:9009
inside a terminal to do that? Or what other ways do i have to get access to Netbeans-internal stuff? (until now, i was just a "user" of Netbeans so i don't know the internals and how to access them very well)
Or will i have to write a Netbeans Plugin to do that? If yes, can you give me a good starting point to add that functionality?
Ok since there is no option to attach the Debugger from commandline, i wrote a Netbeans Plugin with the help of this blog entry and this thread from the NB-mailinglist. Now i'm able to call my plugin actions from the Commandline.
So build a simple NetBeans Module, which contains 2 important classes.
This is the class which gets the commandline parameters and forwards them to my Action:
import java.awt.event.ActionEvent;
import java.util.Collections;
import java.util.Map;
import java.util.Set;
import java.util.logging.Logger;
import javax.swing.Action;
import org.netbeans.api.sendopts.CommandException;
import org.netbeans.spi.sendopts.Env;
import org.netbeans.spi.sendopts.OptionProcessor;
import org.netbeans.spi.sendopts.Option;
import org.openide.ErrorManager;
import org.openide.cookies.InstanceCookie;
import org.openide.filesystems.FileObject;
import org.openide.filesystems.FileUtil;
import org.openide.loaders.DataObject;
import org.openide.util.lookup.ServiceProvider;
import org.openide.windows.WindowManager;
#ServiceProvider(service = OptionProcessor.class)
public class TriggerActionCommandLine extends OptionProcessor {
//Here we specify "runAction" as the new key in the command,
//but it could be any other string you like, of course:
private static Option action = Option.requiredArgument(Option.NO_SHORT_NAME, "debug");
private static final Logger logger = Logger.getLogger(AttachDebugger.class.getName());
#Override
public Set<org.netbeans.spi.sendopts.Option> getOptions() {
return Collections.singleton(action);
}
#Override
protected void process(Env env, Map<Option, String[]> values) throws CommandException {
final String[] args = (String[]) values.get(action);
if (args.length > 0) {
//Set the value to be the first argument from the command line,
//i.e., this is "GreetAction", for example:
final String ip = args[0];
//Wait until the UI is constructed,
//otherwise you will fail to retrieve your action:
WindowManager.getDefault().invokeWhenUIReady(new Runnable() {
#Override
public void run() {
//Then find & perform the action:
Action a = findAction(AttachDebugger.ACTION_NAME);
// forward IP address to Action
ActionEvent e = new ActionEvent(this, 1, ip);
a.actionPerformed(e);
}
});
}
}
public Action findAction(String actionName) {
FileObject myActionsFolder = FileUtil.getConfigFile("Actions/PSFActions");
FileObject[] myActionsFolderKids = myActionsFolder.getChildren();
for (FileObject fileObject : myActionsFolderKids) {
logger.info(fileObject.getName());
//Probably want to make this more robust,
//but the point is that here we find a particular Action:
if (fileObject.getName().contains(actionName)) {
try {
DataObject dob = DataObject.find(fileObject);
InstanceCookie ic = dob.getLookup().lookup(InstanceCookie.class);
if (ic != null) {
Object instance = ic.instanceCreate();
if (instance instanceof Action) {
Action a = (Action) instance;
return a;
}
}
} catch (Exception e) {
ErrorManager.getDefault().notify(ErrorManager.WARNING, e);
return null;
}
}
}
return null;
}
}
This is my Plugin Action which attaches the Debugger to the given remote address:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.netbeans.api.debugger.jpda.DebuggerStartException;
import org.netbeans.api.debugger.jpda.JPDADebugger;
import org.openide.DialogDisplayer;
import org.openide.NotifyDescriptor;
import org.openide.awt.ActionRegistration;
import org.openide.awt.ActionReference;
import org.openide.awt.ActionReferences;
import org.openide.awt.ActionID;
import org.python.util.PythonInterpreter;
#ActionID(category = "PSFActions", id = "de.mackaz.AttachDebugger")
#ActionRegistration(displayName = "#CTL_AttachDebuggerAction")
#ActionReferences({
#ActionReference(path = "Menu/Tools", position = 1800, separatorBefore = 1750, separatorAfter = 1850)
})
public final class AttachDebugger implements ActionListener {
private static final Logger logger = Logger.getLogger(AttachDebugger.class.getName());
public static final String ACTION_NAME="AttachDebugger";
#Override
public void actionPerformed(ActionEvent e) {
String ip;
if (!e.getActionCommand().contains("Attach Debugger")) {
ip = e.getActionCommand();
} else {
ip = lookupIP();
}
try {
logger.log(Level.INFO, "Attaching Debugger to IP {0}", ip);
JPDADebugger.attach(
ip,
9009,
new Object[]{null});
} catch (DebuggerStartException ex) {
int msgType = NotifyDescriptor.ERROR_MESSAGE;
String msg = "Failed to connect debugger to remote IP " + ip;
NotifyDescriptor errorDescriptor = new NotifyDescriptor.Message(msg, msgType);
DialogDisplayer.getDefault().notify(errorDescriptor);
}
}
}
Now i can attach the Netbeans debugger to a specific address by calling netbeans/bin/netbeans --debug 192.168.178.79

Unable to find the org.drools.builder.KnowledgeType drrols class

While am trying to execute the Helloword process example from the section 2.3 in
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html_single/index.html#d4e24 site am unable to find the below mentioned class.
org.drools.builder.KnowledgeType
Could anyone please tell from which package can i get this class?
Thanks!
That part of the documentation seems a little outdated. You should use ResourceType. I've updated the docs with the following code fragment instead (should also appear on the link you're using once the build succeeds):
package com.sample;
