How to write PCF command to get channel status with a condition? - java

Is there a way to write a PCF program to get channel status for Cluster Sender/Receiver channels which are in "Running" status?
I have something like this which gives me channel status of only one channel!
// send the request and collect the responses
String checkStatus="";
String channelName ="";
// build a request
request = new PCFMessage(CMQCFC.MQCMD_INQUIRE_CHANNEL_STATUS);
// add a parameter designating the name of the channel for which status is requested
request.addParameter(CMQCFC.MQCACH_CHANNEL_NAME, "TO.*");
// add a parameter designating the instance type (current) desired
request.addParameter(CMQCFC.MQIACH_CHANNEL_INSTANCE_TYPE, CMQC.MQOT_CURRENT_CHANNEL);
responses = agent.send(request);
for (int j = 0; j < responses.length; j++) {
// get the channel name and trim the spaces
String temp ="";
temp = responses[j].getStringParameterValue(CMQCFC.MQCACH_CHANNEL_NAME);
channelName = temp.trim();
int chlStatus = responses[j].getIntParameterValue(CMQCFC.MQIACH_CHANNEL_STATUS);
//System.out.println("channel status: " + chlStatus);
String[] chStatusText = {
"", "MQCHS_BINDING", "MQCHS_STARTING", "MQCHS_RUNNING",
"MQCHS_STOPPING", "MQCHS_RETRYING", "MQCHS_STOPPED",
"MQCHS_REQUESTING", "MQCHS_PAUSED",
"", "", "", "", "MQCHS_INITIALIZING"
};
checkStatus = chStatusText[chlStatus];
//System.out.println("channel status: " + checkStatus);
}
System.out.println("chl: " + channelName + " STATUS: " + checkStatus + ")");
The above code gives channel status for only one channel and not all the channels. What is wrong here?

The PCF part of your code looks fine, but the printing out of the result is the code in error.
responses = agent.send(request);
for (int j = 0; j < responses.length; j++) {
:
:
checkStatus = chStatusText[chlStatus];
}
System.out.println("chl: " + channelName + " STATUS: " + checkStatus + ")");
You have a for loop going round all the responses, but then the println is outside the for loop and thus is only printing out the result for the final response.

Go grab my open source project called MQ Channel Monitor. Download the source code and review the 'PCFChlStatus.java' file. There is a method called getMCAStatus() which is basically what you are after.

Extracting .pst file to msg but not getting exact number of msg file

I am trying to extract pst file into msg.
I am using aspose jar. I share my code where we get exact number of file in each subfolder.
public static void displayFolderAndMessageInformationForPSTFile(String dataDir) {
// Load the Outlook PST file
PersonalStorage pst = PersonalStorage.fromFile(dataDir + "allen.pst");
// Get the folders information
FolderInfoCollection folderInfoCollection = pst.getRootFolder().getSubFolders();
// Browse through each folder to display folder name and number of messages
for (int i = 0; i < folderInfoCollection.size(); i++) {
FolderInfo folderInfo = (FolderInfo) folderInfoCollection.get_Item(i);
System.out.println("FolderId: " + folderInfo.getEntryIdString());
System.out.println("Folder: " + folderInfo.getDisplayName());
System.out.println("Total items: " + folderInfo.getContentCount());
System.out.println("Total unread items: " + folderInfo.getContentUnreadCount());
System.out.println("-----------------------------------");
}
}
FolderId: AAAAAJJu05VTxVRJlC5mJefQvVeCgAAA
Folder: Inbox
Total items: 66
Total unread items: 0
But when extract message content then i get different number of msg. It give only 49 msg in inbox folder.
The following below code:
public static void main(String[] args) {
String pstFileName = dataDir + "allen.pst";
// Load the Outlook PST file
PersonalStorage pst = PersonalStorage.fromFile(pstFileName);
// Get the folders and messages information
FolderInfo folderInfo = pst.getRootFolder();
// Create a folder for this PST
String strRootFolderName = "allen.pst".replace(".pst", "") + ".Java";
new File(dataDir + strRootFolderName).mkdir();
// Call the recursive method to extract msg files from each folder
extractMsgFiles(folderInfo, pst, dataDir + strRootFolderName);
}
private static void extractMsgFiles(FolderInfo folderInfo, PersonalStorage pst, String strPSTFile) {
// Display the folder name
System.out.println("Folder: " + folderInfo.getDisplayName());
// Create folder to store the messages
String folderName = strPSTFile + "\\" + folderInfo.getDisplayName();
new File(folderName).mkdir();
// Loop through all the messages in this folder
MessageInfoCollection messageInfoCollection = folderInfo.getContents();
for (int i = 0; i < messageInfoCollection.size(); i++) {
MessageInfo messageInfo = (MessageInfo) messageInfoCollection.get_Item(i);
System.out.println("Saving message " + messageInfo.getSubject() + "....");
// Get the message in MapiMessage instance
MapiMessage message = pst.extractMessage(messageInfo);
// Delete special characters which are invalid to use as windows file name
String messageName = null;
if (message.getSubject() == null || message.getSubject().isEmpty() == true) {
messageName = getRidOfIllegalFileNameCharacters(messageInfo.getEntryIdString());
} else {
messageName = getRidOfIllegalFileNameCharacters(message.getSubject());
}
// Save this message to disk in MSG format
message.save(folderName + "\\" + messageName + ".msg");
}
// Call this method recursively for each subfolder
if (folderInfo.hasSubFolders() == true) {
for (int i = 0; i < folderInfo.getSubFolders().size(); i++) {
FolderInfo subfolderInfo = (FolderInfo) folderInfo.getSubFolders().get_Item(i);
extractMsgFiles(subfolderInfo, pst, strPSTFile);
}
}
}
Help me... Where did i make mistake ? I am new in Aspose.
Please have a look at the following code snippet for extracting message files. You may use this method in place of your extractMsgFiles method.
private static void ExtractMsgFiles(FolderInfo folderInfo, PersonalStorage pst)
{
// display the folder name
Console.WriteLine("Folder: " + folderInfo.DisplayName);
Console.WriteLine("==================================");
// loop through all the messages in this folder
MessageInfoCollection messageInfoCollection = folderInfo.GetContents();
foreach (MessageInfo messageInfo in messageInfoCollection)
{
Console.WriteLine("Saving message {0} ....", messageInfo.Subject);
// get the message in MapiMessage instance
MapiMessage message = pst.ExtractMessage(messageInfo);
// save this message to disk in msg format
message.Save(message.Subject.Replace(":", " ") + ".msg");
// save this message to stream in msg format
MemoryStream messageStream = new MemoryStream();
message.Save(messageStream);
}
// Call this method recursively for each subfolder
if (folderInfo.HasSubFolders == true)
{
foreach (FolderInfo subfolderInfo in folderInfo.GetSubFolders())
{
ExtractMsgFiles(subfolderInfo, pst);
}
}
}
You may visit the link Working with Messages in a PST File in case you are interested in more details.
I work with Aspose as Developer evangelist.
The emails not having unique subject names could be causing this issue? I had this exact issue when doing something similar in Powershell. Putting an autonumber in the filename could help get around this.

What does the Redis 'redis.publish()' method do?

What does redis.publish(); method do in the following module.
redis.publish("WordCountTopology", exclamatedWord.toString() + "|" + Long.toString(count));
public void execute(Tuple tuple)
{
String word = tuple.getString(0);
StringBuilder exclamatedWord = new StringBuilder();
exclamatedWord.append(word).append("!!!");
_collector.emit(tuple, new Values(exclamatedWord.toString()));
long count = 30;
redis.publish("WordCountTopology", exclamatedWord.toString() + "|" + Long.toString(count));
}
It publishes the string (ExclamatedWord + "|30") to a Redis channel called WordCountTopology - subscribers to that channel will get the message once redis.publish executes.
For more information about Redis' Pub/Sub see: http://redis.io/topics/pubsub

read IRC data correctly in Processing

I am trying to read IRC and pull data from individual IRC messages in Processing. You can see the code (also with twitter library, ignore that) and I need some pointers on how I can pull the data out in the format of Nick:Message so it can be displayed in a visualization.

The chat commands look like this: :nugshow!nugshow#nugshow.testserver.local PRIVMSG #nugshow :dddd where nugshow is the username, #nugshow is the channel, and dddd is the message. I need to get it into the format of nugshow: dddd.
there is a lot of header information that I'm not sure how to strip out of client.recieved buffer as well, it looks like this:
:testserver.local 001 nugshow :Welcome, GLHF!
:testserver.local 002 nugshow :Your host is testserver.local
:testserver.local 003 nugshow :This server is rather new
:testserver.local 004 nugshow :-
:testserver.local 375 nugshow :-
:testserver.local 372 nugshow :You are in a maze of twisty passages, all alike.
:testserver.local 376 nugshow :>
:nugshow!nugshow#nugshow.testserver.local JOIN #nugshow
:nugshow.testserver.local 353 nugshow = #nugshow :nugshow
:nugshow.testserver.local 366 nugshow #nugshow :End of /NAMES list
:jtv!jtv#jtv.testserver.local PRIVMSG nugshow :HISTORYEND nugshow
I would not recommend regex here. At least not if you want to be able to catch all types of IRC messages. The key is to look at the message code to know what you can actually get out of the message. As I'm also writing an IRC-client (just for giggles) I have some notes for you.
Be sure to answer any PINGs that the server sends you so you don't get kicked off. As the PING is sent with an identifier, you need to catch that and send it back. A simple way to do this is to check the last line that was sent from the server and substring it.
String line = inputStream.readLine();
if(line.substring(0,4).equals("PING")){
send("PONG " + line.substring(5)); // Assume you have some send-function.
}
This will make sure you don't get kicked off and can proceed to actually stay on a server.
As I mentioned, I do not recommend using regex for this as it would become a RegEx-of-doom. So, what I have done is to just split the line you get and put all the results in a String array.
String[] arr = line.split(" ");
As you know by your own message line you have posted, the IRC protocol separates things with spaces. So splitting at spaces in not all that shabby (we'll get how to deal with actual text in a bit).
The basic structure that is always the same (as far as I can tell) in messages is PREFIX COMMAND PARAM PARAM/TRAILING. So what does this mean? The PREFIX is where the message was sent from. Example ":user!user#host.com". The COMMAND is what the line actually is. You are looking for PRIVMSG here, but there are many, many, others that you might want to take care of. Like JOIN, PART, QUIT, 332 (current topic), 353 (nicks in channel, 404 (unable to send to channel), etc. etc. The PARAM and PARAM/TRAILING will all depend on the COMMAND.
So, what do we gain from splitting at spaces? This:
arr[0] = :user!user#host.com
arr[1] = COMMAND
arr[2] = PARAM
arr[3 onwards] = rest
We can now easily manage every command in it's own needed way.
Without further delay, lets get to your actual question, the PRIVMSG.
I will use this string: ":Chewtoy!chewtoy#stackoverflow.com PRIVMSG #stackoverflow :Ty: I saw your question and thought I should give you an answer."
After doing a split at the spaces, we get the array
arr[0] = :Chewtoy!chewtoy#stackoverflow.com
arr[1] = PRIVMSG
arr[2] = #stackoverflow
arr[3] = :Ty:
arr[4] = I
arr[5] = saw
...
As you can see, everything from 3 and onwards is the message you want. 0-2 is stuff that you need to be able to know who sent what where. My code for getting all this looks like this:
String[] arr = receivedLine.split(" ");
if(arr[1].equals("PRIVMSG")){
String[] usr = arr[0].split(!"); // Get the user, which is in usr[0]. Host in usr[1]
StringBuilder msg = new StringBuilder();
for(int i=3; i<arr.length; i++){ // We know the message starts at arr[3], so start counting from that.
msg.append(arr[i] + " ");
}
String chan = "";
if(arr[2].substring(0,1).equals("#")){ // We need to differentiate between sending to channel and sending a PM. The only difference in this is where the text is sent.
chan = arr[2];
} else{
chan = usr[0].substring(1); // substring(1) because we want Chewtoy, not :Chewtoy
}
// The result here will be:
// <#stackoverflow> Chewtoy: Ty: I saw your question and thought I should give you an answer.
sendItAllToWhereYouWantIt("<" + chan +"> " + usr[0].substring(1) + ": " + msg.substring(1));
}
Hope that helps.

Null values on reading custom JAD attributes

I have a blackberry Application. It is downloaded from a web page which provides dynamic JAD file content. The JSP prints those :
out.println("Appid: " + appid);
out.println("Ip: " + user.getIp());
out.println("Servicename: " + service);
out.println("MIDlet-Version: 1.0.0");
out.println("MIDlet-Jar-URL: MyApp.jar");
out.println("MIDlet-Jar-Size: 91633");
out.println("MicroEdition-Profile: MIDP-2.0");
(and other attributes goes on like that..)
I need to get my custom attributes like "Appid" but it sometimes gets null values. User can download and run the app, but some of them cannot get my custom attributes. I dont know it is about the phone model or the current state of OS, but according to my logs, this problem appears mostly on those devices :
9800 with OS 6.0.0.546
9300 with OS 6.0.0.570
9300 with OS 6.0.0.668
9320 with OS 7.1.0.398
My code to get attributes :
CodeModuleGroup cmg = null;
CodeModuleGroup[] allGroups = CodeModuleGroupManager.loadAll();
String moduleName = ApplicationDescriptor
.currentApplicationDescriptor().getModuleName();
for (int i = 0; i < allGroups.length; i++) {
if (allGroups[i].containsModule(moduleName)) {
cmg = allGroups[i];
break;
}
}
if (cmg != null) {
AppData.firstPageURL = cmg.getProperty("Firstpage");
AppData.appId = cmg.getProperty("Appid");
AppData.firstIp = cmg.getProperty("Ip");
AppData.firstSubServiceName = cmg.getProperty("Servicename");
for (Enumeration e = cmg.getPropertyNames(); e.hasMoreElements();) {
String name = (String) e.nextElement();
String value = cmg.getProperty(name);
AppData.errorStep += "-" + name + ":" + value + "-";
}
}
By the way, I determined that the code in the for loop above never runs in these cases.
Any idea ?
Sometimes, ApplicationDescriptor.currentApplicationDescriptor().getModuleName() gives the name of the sibling cod file instead of the main cod file. So, if your module name is MyApp, the function may return MyApp-1.
To solve this, you have to strip out the number after the hyphen.
String moduleName = ApplicationDescriptor.currentApplicationDescriptor()
.getModuleName();
if(moduleName.indexOf('-') > 0) {
moduleName = moduleName.substring(0, moduleName.indexOf('-');
}

Request header is returning NULL

I have some issue with the code below, req.getHeader() is returning NULL
// The code below returns the expected value
String header = req.getHeader("x-key");
String size = req.getHeader("x-size");
String contentType = req.getContentType();
logger.info("Content-Length: " + req.getContentLength());
logger.info("x-key : " + header);
logger.info("x-size : " + size);
// The value of req.getHeader below is returning NULL
for (Enumeration e = req.getHeaderNames(); e.hasMoreElements();) {
String headerName = (String) e.nextElement();
logger.info("Name = " + headerName + " " + "Value = " + req.getHeader(headerName ));
}
What could be the problem?
Your code looks OK. If getHeader() returns null the header is indeed null, i.e. was not sent by client.
So, first check your client and be sure it sends the header. Second, try to use network sniffer, e.g. Wireshark and record the network activity.
If you need more assistance please post your client's code.
The below is part of the extract from the api docs.
public java.util.Enumeration getHeaderNames()
Some servlet containers do not allow servlets to access headers using this method, in which case this method returns null
