Access is denied for writing to ApplicationResources.properties file

For bilingual support in an application I am working on, we are using Spring messaging which uses two files, ApplicationResources.properties and ApplicationResources_fr.properties. This works well.
Now I am trying to expand on this by making it a little more dynamic. The application will read key value pairs from the database and insert them, which gives me the following error:
java.io.FileNotFoundException: \ApplicationResources.properties (Access is denied)
I am able to check on the key value pairs so I know the path I am using is correct. I have also checked the files in Eclipse properties by right clicking, and by visiting the actual file on my system, and they are not read-only. I do not believe they are encrypted because I am able to open and view with notepad++.
Here is my testing code which shows I can view them
Properties test_prop = null;
InputStream is = null;
try {
test_prop = new Properties();
is = this.getClass().getResourceAsStream(en_path);
test_prop.load(is);
Set<Object> keys = test_prop.keySet();
boolean key_found = false;
for(Object k:keys) {
String key = (String)k;
if(key.equals("f12345"))
{
key_found=true;
break;
}
}
System.out.println("Language Properties Test in DAO:" + (key_found? "Key Found" : "Key not found"));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (NullPointerException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Here is where I try to write to the file, and get the error:
ResultSet rs = null;
try (
Connection connection = jdbcTemplate.getDataSource().getConnection();
CallableStatement callableStatement = connection.prepareCall(test_prod_cur);
)
{
callableStatement.registerOutParameter(1, OracleTypes.CURSOR);
callableStatement.executeUpdate();
rs = (ResultSet) callableStatement.getObject(1);
while (rs.next())
{
String thead = rs.getString(1);
//System.out.println(thead + " " + rs.getString(2) + " " + rs.getString(3));
en_prop.setProperty(keyheader+thead, rs.getString(2));
fr_prop.setProperty(keyheader+thead, rs.getString(3));
}
}
catch (SQLException e)
{
System.out.println("SQLException - bilingual values - CLUDAOImpl");
System.out.println(e.getMessage());
}
//add to properties files
//*
try (OutputStream en_os = new FileOutputStream(en_path);)
{
en_prop.store(en_os, null);
} catch (IOException e) {
e.printStackTrace();
}
try(OutputStream fr_os = new FileOutputStream(en_path);)
{
fr_prop.store(fr_os, null);
} catch (IOException e) {
e.printStackTrace();
}
So the database query is successful, that was tested with the commented out system.out.println. It is the following lines that end up throwing the error:
en_prop.store(en_os, null);
fr_prop.store(fr_os, null);
Update: I did a search on the java.util.Properties which lead me to the javadocs on it and wow does that simplify many things. I can now grab a property value or check if the key exists in 6 lines of code (not counting try catch).
Properties prop = null;
InputStream is = null;
this.prop = new Properties();
is = this.getClass().getResourceAsStream(path);
prop.load(is);
this.prop.getProperty("key name"); //returns value of key, or null
this.prop.containsKey("key name"); //returns true if key exists
Update2: There is an issue using java.util.Properties and that is you lose all formatting of the original file, so white-space, comments, and ordering are all lost. In another answer someone suggested using Apache's Commons Configuration API. I plan on trying it out.

So I ended up creating a class to handle interactions with the ApplicationResources(_fr).properties files instead of doing it in the DAO. This was because I plan on using it in more places. I also started using methods from the java.util.Properties Javadocs which proved very helpful and simplified many areas.
Below is my new file write/properties store code.
try (
OutputStream en_os = new FileOutputStream(getClass().getResource(en_path).getFile(),false);
OutputStream fr_os = new FileOutputStream(getClass().getResource(fr_path).getFile(), false);
)
{
en_prop.store(en_os, null);
fr_prop.store(fr_os, null);
} catch (IOException e) {
e.printStackTrace();
}
Lets compare the new and original OutputStreams:
OutputStream en_os = new FileOutputStream(getClass().getResource(en_path).getFile(),false); //new
OutputStream en_os = new FileOutputStream(en_path); //original, Access is Denied
This answer is incomplete for the following reasons.
I am unable to explain why the original method failed and resulted in a "Access is denied error".
More concerning reason to me, this doesnt actually alter the file I am expecting or wanting. I expected to alter the file that appears in my project navigator, but when viewed changes are not observed. If I use an absolute path (C:\...) and overwrite the file then I can alter it as expected, but this path would have to be changed as servers are changed and its bad programming and dangerous. This working method is altering some kind of temp or running file (as confirmed via the path as the file that shows the new values is in the tmp0 folder). After some testing, this temporary file is overwritten on startup only when the original file has been changed, otherwise the new values persist across application starting.
I am also unsure as to the scope of this file. I am unable to tell if all users interacting with the website would cause changes to the same file. If all users are interacting with the file, then potential leakage across sessions could occur. It is also possible that each session has isolated values and could lead to missing information. I suspect that all users are interacting with the same resource but have not performed the testing required to be absolutely positive about this. UPDATE: I have confirmed that all users interact with the same temporary file.

Sikuli - Click on element does not work with Java API but it works from IDE - WPF app

I am evaluating tools for testing a WPF based app. I am currently trying Sikuli with the Java API. When I try to click on an object from Java code, the mouse cursor goes to the object and the object is highlighted, however the click action does not work, because the expected menu does not open. The click() method returns status 1 though.
If I am doing a click from Sikuli IDE, it works fine.
I tried 1.0.1 version and also the nightly build. Here's my code:
#Test
public void testLogin() {
Screen s = new Screen();
try {
s.wait(Constants.overflowMenu);
System.out.println(s.click(Constants.overflowMenu));
s.wait(Constants.signInMenuOption, 5);
} catch (FindFailed e) {
Assert.fail(e.getMessage());
}
}
What am I doing wrong?

try this code, it worked for me. what it does, it checks the image, click on it and then check this image again on the screen, if it still exists, click again.
Screen screen = new Screen();
Pattern pattern = null;
try
{
pattern = new Pattern(imageLocation);
screen.wait(pattern,30);
screen.click(pattern);
System.out.println("First Attempt To Find Image.");
}
catch(FindFailed f)
{
System.out.println("Exception In First Attempt: " +f.getMessage());
System.out.println("FindFailed Exception Handled By Method: ClickObjectUsingSikuli. Please check image being used to identify the webelement. supplied image: " +imageLocation);
Assert.fail("Image wasn't found. Please use correct image.");
}
Thread.sleep(1000);
//In case image/object wasn't clicked in first attempt and cursor stays in the same screen, then do second atempt.
if(screen.exists(pattern) != null)
{
try
{
screen.getLastMatch().click(pattern);
System.out.println("Second Attempt To Find Image.");
System.out.println("Object: " +imageLocation + " is clicked successfully.");
}
catch(FindFailed f)
{
System.out.println("Exception In Second Attempt: " +f.getMessage());
System.out.println("FindFailed Exception Handled By Method: ClickObjectUsingSikuli. Please check image being used to identify the webelement. supplied image: " +imageLocation);
}
}

In my case it seems it was a problem with the fact that I have two monitors..

Eclipse Plug-in use standard Format function in the code

I'm working on a plugin for Eclipse and I created a StructuredTextEditor. The editor contains an XML. And I want to align the code nicely (like indent etc.). I search a possibility to apply the standard function "Format" of Eclipse SHIFT+Ctrl+F.
I found a code snippet that does exaclty this but I didn't get it to work:
String commandId = IJavaEditorActionDefinitionIds.FORMAT;
IHandlerService handlerService = (IHandlerService)PlatformUI.getWorkbench().getService(IHandlerService.class);
try {
handlerService.executeCommand(commandId, null);
} catch (Exception e1) {
e1.printStackTrace();
}
I always get the following Exception:
org.eclipse.core.commands.NotHandledException: There is no handler to execute for command org.eclipse.jdt.ui.edit.text.java.format
Does anyone can help me get running this code, or got en other solution to format the xml content, its important to use the same format like the eclipse formatter uses.

Thanks to greg-449 I searched the correct function to call and found it.
Here is my function that works with StructuredTextEditor.
private void formatString() {
String commandId = "org.eclipse.wst.sse.ui.format.document";
IHandlerService handlerService = (IHandlerService) PlatformUI.getWorkbench().getService(IHandlerService.class);
try {
handlerService.executeCommand(commandId, null);
} catch (Exception e1) {
}
}

error while creating adminclient for websphere 7.0.0.11

I need to develop an application for managing WebSphere Application Server v7.0.0.11. I explored a bit and found out that we can use Mbeans. Actually I need to create something similar as Web-sphere's web console.
My problem is that the application should be in C# .net so is there any connector/Adapter to invoke web-sphere's management API. Please point me in right direction.
I am a C#.net developer and a total newbie in java/websphere, I tried creating Admin Client Example from IBM site by using packages found at IBM/Webshpere/Cimrepos directory. The name of Jar file is com.ibm.wplc.was_7.0.0.11.jar I unzipped that jar file in the same folder.
So now My App is starts, connects to websphere successfully and finds mbean on the nodeAgent. The problem I am facing in invoking mbean. I am getting following error message.
exception invoking launchProcess : javax.management.ReflectionExcetion: Target Method not found com.ibm.ws.management.nodeagent.NodeAgent.launchProcess
I am using following url for list of mbean
http://pic.dhe.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.javadoc.doc/web/mbeanDocs/index.html
i tried using different methods from nodeAgent mbean but no joy , I am always getting same exception "method not found".
Following is the code snipped for invoking launchprocess
private void invokeLaunchProcess(String serverName)
{
// Use the launchProcess operation on the NodeAgent MBean to start
// the given server
String opName = "launchProcess";
String signature[] = { "java.lang.String" };
String params[] = { serverName };
boolean launched = false;
try
{
Boolean b = (Boolean)adminClient.invoke(nodeAgent, opName, params, null);
launched = b.booleanValue();
if (launched)
System.out.println(serverName + " was launched");
else
System.out.println(serverName + " was not launched");
}
catch (Exception e)
{
System.out.println("Exception invoking launchProcess: " + e);
}
}
Full Code could be found on following link
http://pic.dhe.ibm.com/infocenter/wasinfo/v6r0/index.jsp?topic=%2Fcom.ibm.websphere.express.doc%2Finfo%2Fexp%2Fae%2Ftjmx_develop.html
Please let me know what I am doing wrong, do i need to include some other package ? I browsed com.ibm.wplc.was_7.0.0.11.jar, there isn't any folder named nodeagent in com\ibm\ws\managemnt. I found the same jar file in Appserver\runtimes library.
Any help is greatly appreciated, Thanks in Advance.
Getting Mbean
private void getNodeAgentMBean(String nodeName)
{
// Query for the ObjectName of the NodeAgent MBean on the given node
try
{
String query = "WebSphere:type=NodeAgent,node=" + nodeName + ",*";
ObjectName queryName = new ObjectName(query);
Set s = adminClient.queryNames(queryName, null);
if (!s.isEmpty())
nodeAgent = (ObjectName)s.iterator().next();
else
{
System.out.println("Node agent MBean was not found");
System.exit(-1);
}
}
catch (MalformedObjectNameException e)
{
System.out.println(e);
System.exit(-1);
}
catch (ConnectorException e)
{
System.out.println(e);
System.exit(-1);
}catch (Exception e){
e.printStackTrace();
System.exit(-1);
}
System.out.println("Found NodeAgent MBean for node " + nodeName);
}

It seems my problem was with adminClient.invoke method I wasn't passing parameters correctly. It got fixed after having correct parameters. I hope this helps if someone is having same problem.

How can I add URLs to crawler of crawler4j at random times during progress

I'm tackling to crawler4j.
http://code.google.com/p/crawler4j/
and simple test crawl a site was succeeded.
but I want to add URLs at random times during progress.
this code shows the following exception at second constructing CrawlController.
how can I add URLs during progress? or reuse CrawlController?
(also reuse case without re-constructing CrawlController was failed.)
any idea?
or other good crawler in Java?
edit:
since it might be a bug, I posted also to the page of crawler4j.
http://code.google.com/p/crawler4j/issues/detail?id=87&thanks=87&ts=1318661893

As of version 3.0, this feature is implemented in crawler4j. Please visit http://code.google.com/p/crawler4j/source/browse/src/test/java/edu/uci/ics/crawler4j/examples/multiple/ for an example usage.
Basically, you need to start the controller in non-blocking mode:
controller.startNonBlocking(MyCrawler.class, numberOfThreads);
Then you can add your seeds in a loop. Note that you don't need to start the controller several times in a loop.
