• retrieving and restoring textview information from sharedpreferences

  - by user1742524

  I have an activity that allows user to enter notes and store them in dynamically created textviews. However, when the use leaves the activity and returns, all the created textviews disappear. How can i store store or retrieve all of these created textviews, whenever i return to the activity? Also, i think that my sharedpreferences will be overwriting each time a new textview is added. Any suggestions? public class DocNoteActivity extends Activity { private LinearLayout nLayout; private EditText etDocNote; private Button btnAdd1; public static final String PREFS_NAME = "MyPrefsFile"; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.adddocnote); etDocNote = (EditText) findViewById(R.id.editDocNote); btnAdd1 = (Button) findViewById(R.id.btnAdd1); nLayout = (LinearLayout) findViewById(R.id.linearLayout); TextView tvNote = new TextView(this); tvNote.setText(""); btnAdd1.setOnClickListener(onClick()); } private OnClickListener onClick() { // TODO Auto-generated method stub return new OnClickListener(){ public void onClick(View v) { // TODO Auto-generated method stub String newDocNote = etDocNote.getText().toString(); nLayout.addView(createNewTextView(newDocNote)); getSharedPreferences("myprefs", 0).edit().putString("etDocNote", newDocNote).commit(); } }; } private TextView createNewTextView(String newText) { // TODO Auto-generated method stub LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); TextView tvNote = new TextView(this); tvNote.setLayoutParams(lparams); tvNote.setText(newText); return tvNote; } }

• method works fine, until it is called in a function, then UnboundLocalError

  - by user1776100

  I define a method called dist, to calculate the distance between two points which I does it correctly when directly using the method. However, when I get a function to call it to calculate the distance between two points, I get UnboundLocalError: local variable 'minkowski_distance' referenced before assignment edit sorry, I just realised, this function does work. However I have another method calling it that doesn't. I put the last method at the bottom This is the method: class MinkowskiDistance(Distance): def __init__(self, dist_funct_name_str = 'Minkowski distance', p=2): self.p = p def dist(self, obj_a, obj_b): distance_to_power_p=0 p=self.p for i in range(len(obj_a)): distance_to_power_p += abs((obj_a[i]-obj_b[i]))**(p) minkowski_distance = (distance_to_power_p)**(1/p) return minkowski_distance and this is the function: (it basically splits the tuples x and y into their number and string components and calculates the distance between the numeric part of x and y and then the distance between the string parts, then adds them. def total_dist(x, y, p=2, q=2): jacard = QGramDistance(q=q) minkowski = MinkowskiDistance(p=p) x_num = [] x_str = [] y_num = [] y_str = [] #I am spliting each vector into its numerical parts and its string parts so that the distances #of each part can be found, then summed together. for i in range(len(x)): if type(x[i]) == float or type(x[i]) == int: x_num.append(x[i]) y_num.append(y[i]) else: x_str.append(x[i]) y_str.append(y[i]) num_dist = minkowski.dist(x_num,y_num) str_dist = I find using some more steps #I am simply adding the two types of distance to get the total distance: return num_dist + str_dist class NearestNeighbourClustering(Clustering): def __init__(self, data_file, clust_algo_name_str='', strip_header = "no", remove = -1): self.data_file= data_file self.header_strip = strip_header self.remove_column = remove def run_clustering(self, max_dist, p=2, q=2): K = {} #dictionary of clusters data_points = self.read_data_file() K[0]=[data_points[0]] k=0 #I added the first point in the data to the 0th cluster #k = number of clusters minus 1 n = len(data_points) for i in range(1,n): data_point_in_a_cluster = "no" for c in range(k+1): distances_from_i = [total_dist(data_points[i],K[c][j], p=p, q=q) for j in range(len(K[c]))] d = min(distances_from_i) if d <= max_dist: K[c].append(data_points[i]) data_point_in_a_cluster = "yes" if data_point_in_a_cluster == "no": k += 1 K[k]=[data_points[i]] return K

• Using Moq to Validate Separate Invocations with Distinct Arguments

  - by Thermite

  I'm trying to validate the values of arguments passed to subsequent mocked method invocations (of the same method), but cannot figure out a valid approach. A generic example follows: public class Foo { [Dependency] public Bar SomeBar { get; set; } public void SomeMethod() { this.SomeBar.SomeOtherMethod("baz"); this.SomeBar.SomeOtherMethod("bag"); } } public class Bar { public void SomeOtherMethod(string input) { } } public class MoqTest { [TestMethod] public void RunTest() { Mock<Bar> mock = new Mock<Bar>(); Foo f = new Foo(); mock.Setup(m => m.SomeOtherMethod(It.Is<string>("baz"))); mock.Setup(m => m.SomeOtherMethod(It.Is<string>("bag"))); // this of course overrides the first call f.SomeMethod(); mock.VerifyAll(); } } Using a Function in the Setup might be an option, but then it seems I'd be reduced to some sort of global variable to know which argument/iteration I'm verifying. Maybe I'm overlooking the obvious within the Moq framework?

• seriouosly elusive for loop (racking my brains!)

  - by user1693359

  I've got a loop issue in Python 2.72 that's really frustrating me. Basically the loop is not iterating fast the first index (j), and I've tried all sorts of ways to fix it with no luck. def learn(dataSet): for i in dataSet.getNext(): recall = raw_input("Enter all members of %s you are able to recall >>> (separated by commas) " % (i.getName())) missed = i.getMembers() missedString = [] for a in missed: missedString.append(a.getName()) Here is the loop I can't get to iterate. The first for loop only goes through the first iteration of 'j' in the split string list, then removes it from 'missedString'. I would like for all members of the split-string 'recall' to be removed from 'missedString'. for j in string.split(recall, ','): if j in missedString: missedString.remove(j) continue for b in missed: if b.getName() not in missedString: missed.remove(b) print 'You missed %d. ' % (len(missed)) if (len(missed)) > 0: print 'Maybe a hint or two will help...' for miss in missed: remind(miss.getSecs(), i.getName(), missed) I really have no clue, help would be appreciated!

• Struct containing a Map in a Map? (C++/STL)

  - by karok

  I was wondering if it was possible to create a struct containing a number of variables and a map in a map. What I have at the moment: typedef std::map<std::string,double> lawVariables; struct ObjectCustomData { std::string objectType; bool global_lock; std::map<std::string, lawVariables> lawData; }; This struct is then passed on to another function as a single data block for that object. The structure setup is as follows: Each object has a data block that contains: its ObjectType, a bool for a lock, and a varying number of "laws" that could look like this: law1 -> var_a = 39.3; -> var_g = 8.1; law8 -> var_r = 83.1; -> var_y = 913.3; -> var_a = 9.81; Firstly, I'm unsure whether I should be using a Map within a Map and secondly even if this would be valid, I'm unsure how to fill it with data and how to recall it afterwards. I looked at maps because then I can search (on a name) if a certain object has a certain law, and if that law has certain variables. (sorry for the first messy post appearance, hope this is better :) )

• WCF client side List<> problem

  - by MrKanin

  Hey there.. i got a WCF service with a method (GetUserSoftware)to send a List to a client. the software i have difined like this: [DataContract] public class Software { public string SoftwareID { get; set; } public string SoftwareName { get; set; } public string DownloadPath { get; set; } public int PackageID { get; set; } } the method is going through my db to get all software availeble to the clien, and generates a list of that to send back to the client. problem is i on the client side the list is turned into an array. and every item in that array dont contain any of my software attributs. i have debugged my way through the server side. and seen that the list its about to send is correct. with the expected software and attributs in it. any one know how to work around this or know what i can do ?

• ArrayIndexOutOfBoundsException double array size

  - by Andy

  I'm going to preface this question with this statement: I know that I can easily handle this problem by reading the amount of lines in a file and making an array that size. I am not allowed to do this. Anyway, here is my question. I need to double my array's size whenever my program encounters an ArrayIndexOutOfBoundsException and then copy all the previous read in information into the larger array. Here is my code public static void main(String[] args) throws IOException { Scanner inScan, fScan = null; int [] A = new int[5]; inScan = new Scanner(System.in); System.out.print("Please enter the file to read from: "); while(true) { try{ String fName = inScan.nextLine(); fScan = new Scanner(new File(fName)); break; } catch (FileNotFoundException ex) { System.out.println("Your file is invalid -- please re-enter"); } } String nextItem; int nextInt = 0; int i = 0; while (fScan.hasNextLine()) { try { nextItem = fScan.nextLine(); nextInt = Integer.parseInt(nextItem); A[i] = nextInt; i++; } catch (NumberFormatException e) { System.out.println("Found an invalid int -- ignored"); } catch (ArrayIndexOutOfBoundsException e) { //double the size of array A until //copy all previous read in information to the larger array } } System.out.println("Here are your " + i + " items:"); for (int j = 0; j < i; j++) { System.out.println(A[j] + " "); } } }

• convert a repeating code to method

  - by Mr_Green

  In my project, I am adding ComboBox, Text, Link label to my DataGridView dgvMain.I have created different methods for different cell templates as shown below: (The code below is working) gridLnklbl(string headerName) DataGridViewLinkColumn col = new DataGridViewLinkColumn(); col.HeaderText = headerName; // col.Name = "col" + headerName; // same code repeating to all the methods dgvMain.Columns.Add(col); // gridCmb(string headerName) DataGridViewComboBoxColumn col = new DataGridViewComboBoxColumn(); col.HeaderText = headerName; col.Name = "col" + headerName; dgvMain.Columns.Add(col); gridText(string headerName) DataGridViewTextBoxColumn col = new DataGridViewTextBoxColumn(); col.HeaderText = headerName; col.Name = "col" + headerName; dgvMain.Columns.Add(col); As you can see, except the declaration of objects, the code for every method is repeating. Just curious to know, can the repeating code be converted to single method? I dont know how to do that.. Its not about 3 codes of line, I have written many more lines which can be make common to those methods.

• C# return and display syntax issue

  - by thatdude

  I am having trouble passing the return value from TheMethod() to Main and displaying the word if the if statement is passed as true. I have thought of two ways of doing this, neither has worked but I think I am missing synatx. Using a return ?; non void method and then displaying the returned value. Using a void method and actually writing out(example below) So yes I am new at this, however I have made so many iterations everything is blending together and I have forgot what I have tried. Any help on the syntax be great for either of these ways. Basically I need it to iterate numbers 1,2,3,4 and depending on if the current iteration matches an expression in the if statements it will display a word. Example: if (3 = i) { Console.WriteLine("Word"); } Code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Proj5 { class Program { int i = 0; static void Main(int i) { for (i = 0; i < 101; i++) { Console.WriteLine("test"); } } string TheMethod(int i) { string f = "Word1"; string b = "Word2"; if (i == 3) { return f; } if (i == 5) { return b; } if (0 == (i % 3)) { return f; } if (0 == i % 5) { return b; } else { return b; } } } }

• FileVersionInfo.GetVersionInfo getting old version of an exe swapped at runtime

  - by Richard

  I have a program executing in c# that is sometimes updated while it is running by swapping the exe to a new one. I want the program to routinely check if it has been updated and if so, restart. I use the following function to do this. public static bool DoINeedToRestart(string exe_name) { Version cur_version = new Version(MainProgram.StartVersion); Version file_version = new Version(GetProductVersion(exe_name)); MessageBox.Show("Comparing cur_version " + cur_version.ToString() + " with " + file_version.ToString()); if (file_version > cur_version) { return true; } return false; } public static string GetProductVersion(string path_name) { FileVersionInfo myFI = FileVersionInfo.GetVersionInfo(path_name); return myFI.FileVersion; } MainProgram.StartVersion is set when the program is started to be the current version using the GetProductVersion(exe_name) exe_name is set to be the name of the executable that is being updated. The problem I have is once the MainProgram.exe file has been updated (I verify this manually by looking at the file properties and checking the file version), the GetProductVersion still returns the old file version and I have no idea why! Any help is greatly appreciated.

• Compression Program in C

  - by Delandilon

  I want to compress a series of characters. For example if i type Input : FFFFFBBBBBBBCCBBBAABBGGGGGSSS (27 x 8 bits = 216 bits) Output: F5B7C2B3A2B2G5S3 (14 x 8 bits = 112bits) So far this is what i have, i can count the number of Characters in the Array. But the most important task is to count them in the same sequence. I can't seem to figure that out :( Ive stared doing C just a few weeks back, i have knowledge on Array, pointers, ASCII value but in any case can't seem to count these characters in a sequence. Ive try a bit of everything. This approach is no good but it the closest i came to it. #include <stdio.h> #include <conio.h> int main() { int charcnt=0,dotcnt=0,commacnt=0,blankcnt=0,i, countA, countB; char str[125]; printf("*****String Manipulations*****\n\n"); printf("Enter a string\n\n"); scanf("%[^'\n']s",str); printf("\n\nEntered String is \" %s \" \n",str); for(i=0;str[i]!='\0';i++) { // COUNTING EXCEPTION CHARS if(str[i]==' ') blankcnt++; if(str[i]=='.') dotcnt++; if(str[i]==',') commacnt++; if (str[i]=='A' || str[i]=='a') countA++; if (str[i]=='B' || str[i]=='b') countA++; } //PRINT RESULT OF COUNT charcnt=i; printf("\n\nTotal Characters : %d",charcnt); printf("\nTotal Blanks : %d",blankcnt); printf("\nTotal Full stops : %d",dotcnt); printf("\nTotal Commas : %d\n\n",commacnt); printf("A%d\n", countA); }

• How To Create a lookup Table with an NSDate for weekly range (over 5 year period)

  - by EarlyMan

  Unsure how to best achieve this. NSDate *date = [NSDate date]; I need to do a lookup on the date and return a string value. 12/17/2011 < date < 12/23/2011 return "20120101" 12/24/2011 < date < 12/30/2012 return "20120102" 12/31/2011 < date < 01/06/2012 return "20120201" ... 10/20/2012 < date < 10/26/2012 return "20122301" ... 11/02/2013 < date < 11/08/2013 return "20132301" .. for 5 years... for each week date can be any date until Dec. 2017. I do not know the logic behind the return strings so I can't simply calculate the string based on the date. The return string (converted to NSDate in the model) is used successfully as my section for my fetchedresultscontroller. I am not sure how to create a lookup table based on an NSDate or if I need some monster if/case statement.

• selected option not clearing from memory android

  - by user2980560

  I have a small random number spinner that when you click gives a random number. I am having two problems. The first is when the main activity loads it displays a random number on the screen without the random number spinner being clicked. I am unsure what to set to false to keep it from opening with the main activity. The second problem is that when you select an option from the spinner it does not clear. Meaning that If you click on option D6 or D20 then you can not click on the same option again until selecting the other option first. Essentially the selection does not clear out of memory after the random number is selected. Here is the random number code public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) { Random rand = new Random(); int roll; // An item was selected. if (spinner1.getSelectedItemPosition()==0) { roll = rand.nextInt(6)+1; } else { roll = rand.nextInt(20)+1; } // Put the result into a string. String text = "You rolled a " + roll; // Build a dialog box and with the result string and a single button AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage(text).setCancelable(false) .setPositiveButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { // do things when the user clicks ok. } }); AlertDialog alert = builder.create(); // Show the dialog box. alert.show(); }

• Generating an identifier for objects so that they can be added to a hashtable I have created

  - by dukenukem

  I have a hashtable base class and I am creating different type of hashtable by deriving from it. I only allow it to accept objects that implement my IHashable interface.For example - class LinearProbingHashTable<T> : HashTableBase<T> where T: IHashable { ... ... ... } interface IHashable { /** * Every IHashable implementation should provide an indentfying value for use in generating a hash key. */ int getIdentifier(); } class Car : IHashable { public String Make { get; set; } public String Model { get; set; } public String Color { get; set; } public int Year { get; set; } public int getIdentifier() { /// ??? } } Can anyone suggest a good method for generating an identifier for the car that can be used by the hash function to place it in the hash table? I am actually really looking for a general purpose solution to generating an id for any given class. I would like to have a base class for all classes, HashableObject, that implements IHashable and its getIdentifier method. So then I could just derive from HashableObject which would automatically provide an identifier for any instances. Which means I wouldn't have to write a different getIdentifier method for every object I add to the hashtable. public class HashableObject : IHashable { public int getIdentifier() { // Looking for code here that would generate an id for any object... } } public class Dog : HashableObject { // Dont need to implement getIdentifier because the parent class does it for me }

The previous posts were: JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue JMS Step 3 - Using the QueueReceive.java Sample Program to Read a Message from a JMS Queue JMS Step 4 - How to Create an 11g BPEL Process Which Writes a Message Based on an XML Schema to a JMS Queue Today we will create a BPEL process which will read (dequeue) the message from the JMS queue, which we enqueued in the last example. The JMS adapter will dequeue the full XML payload from the queue. 1. Recap and Prerequisites In the previous examples, we created a JMS Queue, a Connection Factory and a Connection Pool in the WebLogic Server Console. Then we designed and deployed a BPEL composite, which took a simple XML payload and enqueued it to the JMS queue. In this example, we will read that same message from the queue, using a JMS adapter and a BPEL process. As many of the configuration steps required to read from that queue were done in the previous samples, this one will concentrate on the new steps. A summary of the required objects is listed below. To find out how to create them please see the previous samples. They also include instructions on how to verify the objects are set up correctly. WebLogic Server Objects Object Name Type JNDI Name TestConnectionFactory Connection Factory jms/TestConnectionFactory TestJMSQueue JMS Queue jms/TestJMSQueue eis/wls/TestQueue Connection Pool eis/wls/TestQueue Schema XSD File The following XSD file is used for the message format. It was created in the previous example and will be copied to the new process. stringPayload.xsd <?xml version="1.0" encoding="windows-1252" ?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"                 xmlns="http://www.example.org"                 targetNamespace="http://www.example.org"                 elementFormDefault="qualified">   <xsd:element name="exampleElement" type="xsd:string">   </xsd:element> </xsd:schema> JMS Message After executing the previous samples, the following XML message should be in the JMS queue located at jms/TestJMSQueue: <?xml version="1.0" encoding="UTF-8" ?><exampleElement xmlns="http://www.example.org">Test Message</exampleElement> JDeveloper Connection You will need a valid Application Server Connection in JDeveloper pointing to the SOA server which the process will be deployed to. 2. Create a BPEL Composite with a JMS Adapter Partner Link In the previous example, we created a composite in JDeveloper called JmsAdapterWriteSchema. In this one, we will create a new composite called JmsAdapterReadSchema. There are probably many ways of incorporating a JMS adapter into a SOA composite for incoming messages. One way is design the process in such a way that the adapter polls for new messages and when it dequeues one, initiates a SOA or BPEL instance. This is possibly the most common use case. Other use cases include mid-flow adapters, which are activated from within the BPEL process. In this example we will use a polling adapter, because it is the most simple to set up and demonstrate. But it has one disadvantage as a demonstrative model. When a polling adapter is active, it will dequeue all messages as soon as they reach the queue. This makes it difficult to monitor messages we are writing to the queue, because they will disappear from the queue as soon as they have been enqueued. To work around this, we will shut down the composite after deploying it and restart it as required. (Another solution for this would be to pause the consumption for the queue and resume consumption again if needed. This can be done in the WLS console JMS-Modules -> queue -> Control -> Consumption -> Pause/Resume.) We will model the composite as a one-way incoming process. Usually, a BPEL process will do something useful with the message after receiving it, such as passing it to a database or file adapter, a human workflow or external web service. But we only want to demonstrate how to dequeue a JMS message using BPEL and a JMS adapter, so we won’t complicate the design with further activities. However, we do want to be able to verify that we have read the message correctly, so the BPEL process will include a small piece of embedded java code, which will print the message to standard output, so we can view it in the SOA server’s log file. Alternatively, you can view the instance in the Enterprise Manager and verify the message. The following steps are all executed in JDeveloper. Create the project in the same JDeveloper application used for the previous examples or create a new one. Create a SOA Project Create a new project and choose SOA Tier > SOA Project as its type. Name it JmsAdapterReadSchema. When prompted for the composite type, choose Empty Composite. Create a JMS Adapter Partner Link In the composite editor, drag a JMS adapter over from the Component Palette to the left-hand swim lane, under Exposed Services. This will start the JMS Adapter Configuration Wizard. Use the following entries: Service Name: JmsAdapterRead Oracle Enterprise Messaging Service (OEMS): Oracle WebLogic JMS AppServer Connection: Use an application server connection pointing to the WebLogic server on which the JMS queue and connection factory mentioned under Prerequisites above are located. Adapter Interface > Interface: Define from operation and schema (specified later) Operation Type: Consume Message Operation Name: Consume_message Consume Operation Parameters Destination Name: Press the Browse button, select Destination Type: Queues, then press Search. Wait for the list to populate, then select the entry for TestJMSQueue , which is the queue created in a previous example. JNDI Name: The JNDI name to use for the JMS connection. As in the previous example, this is probably the most common source of error. This is the JNDI name of the JMS adapter’s connection pool created in the WebLogic Server and which points to the connection factory. JDeveloper does not verify the value entered here. If you enter a wrong value, the JMS adapter won’t find the queue and you will get an error message at runtime, which is very difficult to trace. In our example, this is the value eis/wls/TestQueue . (See the earlier step on how to create a JMS Adapter Connection Pool in WebLogic Server for details.) Messages/Message SchemaURL: We will use the XSD file created during the previous example, in the JmsAdapterWriteSchema project to define the format for the incoming message payload and, at the same time, demonstrate how to import an existing XSD file into a JDeveloper project. Press the magnifying glass icon to search for schema files. In the Type Chooser, press the Import Schema File button. Select the magnifying glass next to URL to search for schema files. Navigate to the location of the JmsAdapterWriteSchema project > xsd and select the stringPayload.xsd file. Check the “Copy to Project” checkbox, press OK and confirm the following Localize Files popup. Now that the XSD file has been copied to the local project, it can be selected from the project’s schema files. Expand Project Schema Files > stringPayload.xsd and select exampleElement: string . Press Next and Finish, which will complete the JMS Adapter configuration.Save the project. Create a BPEL Component Drag a BPEL Process from the Component Palette (Service Components) to the Components section of the composite designer. Name it JmsAdapterReadSchema and select Template: Define Service Later and press OK. Wire the JMS Adapter to the BPEL Component Now wire the JMS adapter to the BPEL process, by dragging the arrow from the adapter to the BPEL process. A Transaction Properties popup will be displayed. Set the delivery mode to async.persist. This completes the steps at the composite level. 3 . Complete the BPEL Process Design Invoke the BPEL Flow via the JMS Adapter Open the BPEL component by double-clicking it in the design view of the composite.xml, or open it from the project navigator by selecting the JmsAdapterReadSchema.bpel file. This will display the BPEL process in the design view. You should see the JmsAdapterRead partner link in the left-hand swim lane. Drag a Receive activity onto the BPEL flow diagram, then drag a wire (left-hand yellow arrow) from it to the JMS adapter. This will open the Receive activity editor. Auto-generate the variable by pressing the green “+” button and check the “Create Instance” checkbox. This will result in a BPEL instance being created when a new JMS message is received. At this point it would actually be OK to compile and deploy the composite and it would pick up any messages from the JMS queue. In fact, you can do that to test it, if you like. But it is very rudimentary and would not be doing anything useful with the message. Also, you could only verify the actual message payload by looking at the instance’s flow in the Enterprise Manager. There are various other possibilities; we could pass the message to another web service, write it to a file using a file adapter or to a database via a database adapter etc. But these will all introduce unnecessary complications to our sample. So, to keep it simple, we will add a small piece of Java code to the BPEL process which will write the payload to standard output. This will be written to the server’s log file, which will be easy to monitor. Add a Java Embedding Activity First get the full name of the process’s input variable, as this will be needed for the Java code. Go to the Structure pane and expand Variables > Process > Variables. Then expand the input variable, for example, "Receive1_Consume_Message_InputVariable > body > ns2:exampleElement”, and note variable’s name and path, if they are different from this one. Drag a Java Embedding activity from the Component Palette (Oracle Extensions) to the BPEL flow, after the Receive activity, then open it to edit. Delete the example code and replace it with the following, replacing the variable parts with those in your sample, if necessary.: System.out.println("JmsAdapterReadSchema process picked up a message"); oracle.xml.parser.v2.XMLElement inputPayload =    (oracle.xml.parser.v2.XMLElement)getVariableData(                           "Receive1_Consume_Message_InputVariable",                           "body",                           "/ns2:exampleElement");   String inputString = inputPayload.getFirstChild().getNodeValue(); System.out.println("Input String is " + inputPayload.getFirstChild().getNodeValue()); Tip. If you are not sure of the exact syntax of the input variable, create an Assign activity in the BPEL process and copy the variable to another, temporary one. Then check the syntax created by the BPEL designer. This completes the BPEL process design in JDeveloper. Save, compile and deploy the process to the SOA server. 3. Test the Composite Shut Down the JmsAdapterReadSchema Composite After deploying the JmsAdapterReadSchema composite to the SOA server it is automatically activated. If there are already any messages in the queue, the adapter will begin polling them. To ease the testing process, we will deactivate the process first Log in to the Enterprise Manager (Fusion Middleware Control) and navigate to SOA > soa-infra (soa_server1) > default (or wherever you deployed your composite to) and click on JmsAdapterReadSchema [1.0] . Press the Shut Down button to disable the composite and confirm the following popup. Monitor Messages in the JMS Queue In a separate browser window, log in to the WebLogic Server Console and navigate to Services > Messaging > JMS Modules > TestJMSModule > TestJMSQueue > Monitoring. This is the location of the JMS queue we created in an earlier sample (see the prerequisites section of this sample). Check whether there are any messages already in the queue. If so, you can dequeue them using the QueueReceive Java program created in an earlier sample. This will ensure that the queue is empty and doesn’t contain any messages in the wrong format, which would cause the JmsAdapterReadSchema to fail. Send a Test Message In the Enterprise Manager, navigate to the JmsAdapterWriteSchema created earlier, press Test and send a test message, for example “Message from JmsAdapterWriteSchema”. Confirm that the message was written correctly to the queue by verifying it via the queue monitor in the WLS Console. Monitor the SOA Server’s Output A program deployed on the SOA server will write its standard output to the terminal window in which the server was started, unless this has been redirected to somewhere else, for example to a file. If it has not been redirected, go to the terminal session in which the server was started, otherwise open and monitor the file to which it was redirected. Re-Enable the JmsAdapterReadSchema Composite In the Enterprise Manager, navigate to the JmsAdapterReadSchema composite again and press Start Up to re-enable it. This should cause the JMS adapter to dequeue the test message and the following output should be written to the server’s standard output: JmsAdapterReadSchema process picked up a message. Input String is Message from JmsAdapterWriteSchema Note that you can also monitor the payload received by the process, by navigating to the the JmsAdapterReadSchema’s Instances tab in the Enterprise Manager. Then select the latest instance and view the flow of the BPEL component. The Receive activity will contain and display the dequeued message too. 4 . Troubleshooting This sample demonstrates how to dequeue an XML JMS message using a BPEL process and no additional functionality. For example, it doesn’t contain any error handling. Therefore, any errors in the payload will result in exceptions being written to the log file or standard output. If you get any errors related to the payload, such as Message handle error ... ORABPEL-09500 ... XPath expression failed to execute. An error occurs while processing the XPath expression; the expression is /ns2:exampleElement. ... etc. check that the variable used in the Java embedding part of the process was entered correctly. Possibly follow the tip mentioned in previous section. If this doesn’t help, you can delete the Java embedding part and simply verify the message via the flow diagram in the Enterprise Manager. Or use a different method, such as writing it to a file via a file adapter. This concludes this example. In the next post, we will begin with an AQ JMS example, which uses JMS to write to an Advanced Queue stored in the database.

  Hi, I have the following NavigableImagePanel, it is under BSD license and I found it in the web.

• Search multiple datepicker on same grid

  - by DHF

  I'm using multiple datepicker on same grid and I face the problem to get a proper result. I used 3 datepicker in 1 grid. Only the first datepicker (Order Date)is able to output proper result while the other 2 datepicker (Start Date & End Date) are not able to generate proper result.

• Mac OS X Server Configure DHCP Options 66 and 67

  - by Paul Adams

  I need to configure Mountain Lion (10.8.2) OS X Server BOOTP to provide DHCP options 66 and 67 to provide PXE booting for PCs on my network. I have tried following the bootpd MAN pages, but they are not specific enough. I have also read conflicting information on the net, but nothing definitive for Mountain Lion DHCP. From bootpd man page: bootpd has a built-in type conversion table for many more options, mostly those specified in RFC 2132, and will try to convert from whatever type the option appears in the property list to the binary, packet format. For example, if bootpd knows that the type of the option is an IP address or list of IP addresses, it converts from the string form of the IP address to the binary, network byte order numeric value. If the type of the option is a numeric value, it converts from string, integer, or boolean, to the proper sized, network byte-order numeric value. Regardless of whether bootpd knows the type of the option or not, you can always specify the DHCP option using the data property list type <key>dhcp_option_128</key> <data> AAqV1Tzo </data> My TFTP server is 172.16.152.20 and the bootfile is pxelinux.0 I have edited /etc/bootpd.plist and added the following to the subnet dict: <key>dhcp_option_66</key> <data> LW4gLWUgrBCYFAo= </data> <key>dhcp_option_67</key> <data> LW4gLWUgcHhlbGludXguMAo= </data> According to the man page, the data elements are supposed to be Base64 encoded, but no matter what I try, I cannot get PXE clients to boot. I have tried encoding 172.16.152.20 using various methods: echo "172.16.152.20" | openssl enc -base64 returns MTcyLjE2LjE1Mi4yMAo= DHCP Option Code Utility (http://mac.softpedia.com/get/Internet-Utilities/DHCP-Option-Code-Utility.shtml) generating a string from 172.16.152.20 yields: LW4gLWUgMTcyLjE2LjE1Mi4yMAo= (used in the above example) DHCP Option Code Utility generating an IP Addresss from 172.16.152.20 yields: LW4gLWUgrBCYFAo= Encoding pxelinux.0 with the above methods likewise yields different encodings. I have tried using all three methods of encoding the data elements, but nothing seems to work i.e. my PXE boot clients do not get directed to my TFTP server. Can anyone help? Regards, Paul Adams.

• Why can I not get a WDS-originated PXE boot to progress past the first file download?

  - by Jeff Shattock

  I'm trying to work out an automated Windows install process, and thought I'd give WDS a look. After some promising initial progress, I seem to have hit a wall. I imported the boot and install WIMs, and created the capture WIM successfully. However, whenever I try to PXE boot the reference machine against the WDS server, it kinda craps out. It finds the server and downloads WDSNBP.COM successfully, and then gives the message "TFTP download failed." According to WireShark, the only communication between the WDS box and the client box is the successful TFTP request and download of boot\x86\WDSNBP.COM. No further requests are sent. The WDS log on the server shows the same thing, one successful download and no more activity. I've tried every combination of the following, with exactly zero change in behaviour: Win Server 2008R2 vs 2012 vs 2012R2 WDS virtualized on KVM, ESXi, VirtualBox, VMWare Workstation Client virtualized on KVM, ESXi, VirtualBox, VMWare Workstation Every network adaptor type offered by the virtualization platforms. "Actual" network vs isolated, virtual network. MS DHCP server vs Linux isc-dhcp-server Joined to a domain vs Stand-alone I tried changing the boot filename in DHCP to pxeboot.com instead, and it has no problem downloading that file instead, but it then crabs about Boot\BCD being corrupted. Also, with 2012, it doesnt appear that WDSNBP.com does the architecture detection, or at least does'nt report that it did. 2008 reports that it found x64, and then errors. I find myself out of things to check, and I dont see anything immediately wrong. Where do I go from here? WDS server is at 192.168.1.50, DHCP/DNS at 192.168.1.7.

• SNMP: how to get combined output of memBuffer, memCached and memAvailReal?

  - by user492160

  Below is the output of 'free -m' on my system: total used free shared buffers cached Mem: 2026 1936 90 0 212 649 -/+ buffers/cache: 1074 952 Swap: 3359 0 3359 I'd like to retrieve the value 952 of -/+ buffers/cache using 'snmpwalk'. This is for integrating 'free memory' availability with Cacti-poller. But currently the only values available are: # snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2021.4 UCD-SNMP-MIB::memIndex.0 = INTEGER: 0 UCD-SNMP-MIB::memErrorName.0 = STRING: swap UCD-SNMP-MIB::memTotalSwap.0 = INTEGER: 3440632 UCD-SNMP-MIB::memAvailSwap.0 = INTEGER: 3440576 UCD-SNMP-MIB::memTotalReal.0 = INTEGER: 2075556 UCD-SNMP-MIB::memAvailReal.0 = INTEGER: 92552 UCD-SNMP-MIB::memTotalFree.0 = INTEGER: 3533128 UCD-SNMP-MIB::memMinimumSwap.0 = INTEGER: 16000 UCD-SNMP-MIB::memShared.0 = INTEGER: 0 UCD-SNMP-MIB::memBuffer.0 = INTEGER: 217388 UCD-SNMP-MIB::memCached.0 = INTEGER: 664904 UCD-SNMP-MIB::memSwapError.0 = INTEGER: 0 UCD-SNMP-MIB::memSwapErrorMsg.0 = STRING: Is it possible to retrieve the combined value of memBuffer+memCached+memAvailReal using snmpwalk for graphing with Cacti and RRDTool? If not what options do I possibly have? I'm using net-snmp 5.3.2 on my agent host. Thanks in advance.

• how to reference a ppp adapter in windows command?

  - by ollydbg23

  When using the windows command ipconfig /all, the result will show a PPP adapter followed by a long name closed with braces. It looks like the below image: When I try to set the DNS of my PPP adapter, I encounter this problem: netsh interface ip set dns "PPP adapter {1C43A7B0-1173-40E2-96D6-1DA6457786B0}" static 208.67.222.222 Invalid interface PPP adapter {1C43A7B0-1173-40E2-96D6-1DA6457786B0} specified. I have also used the pure string "{1C43A7B0-1173-40E2-96D6-1DA6457786B0}", but with the same result. How can I reference this PPP adapter, so that I can change its configured DNS and other settings? What does this long string mean? I do not have this PPP adapter connection on my "show all connections" panel, because I have a VPN app - when running it, this PPP adapter will be automatically created for me.
