I am trying to write a simple Java program that reads from JBossMQ's jms_messages table using JDBC. I am using JBoss 4.0.4.GA.
I can get the as far as getting a SpyMessage, but how can I get the actual message content (which is an Object in the particular case I'm looking at).
I have a result set "rs" from this statement:
SELECT messageid, messageblob FROM jms_messages WHERE DESTINATION LIKE 'TOPIC.MyTopic%' limit 3"
and then I do this (based on JBoss code):
long messageid = rs.getLong(1);
SpyMessage message = null;
byte[] st = rs.getBytes(2);
ByteArrayInputStream baip = new ByteArrayInputStream(st);
ObjectInputStream ois = new ObjectInputStream(baip);
message = SpyMessage.readMessage(ois);
message.header.messageId = messageid;
String jmstype = message.getJMSType();
String jms_message_id = message.getJMSMessageID();
System.out.println("jmstype=" +jmstype);
System.out.println("jms_message_id=" +jms_message_id);
String propertyName;
Enumeration e = message.getPropertyNames();
while (e.hasMoreElements())
{
propertyName = (String)e.nextElement();
System.out.println("property name = " +propertyName);
}
but I get no properties printed and I don't know how to get my actual object from the SpyMessage (actually a SpyObjectMessage). I'd be grateful for any pointers.
I've tried asking this question on the JBoss forum without reply, so I'm hoping for better luck here.
Thanks.
Sorry - the answer was so obvious I'm not really sure what I was thinking when I posted the question - simply:
Object objMessage = ((SpyObjectMessage)message).getObject();

Below is the code written by my collegue who doesnt work in the firm anymore. I am inserting records in object with data loader and I can see success message but I do not see any records in my object. I am not able to understand what below trigger is doing.Please someone help me understand as I am new to salesforce.

You might be looking in the wrong place. Check if there's an unit test written for this thing (there should be one, especially if it's deployed to production), it should help you understand how it's supposed to be used.
You're inserting records of QMBDataLogging__c but then it seems they're immediately deleted in DeleteDoAsLoggingRecords.deleteTheProcessRecords(processdIds). Whether whatever this thing was supposed to do succeeds or not.
This seems to be some poor man's CSV parser or generic "upload anything"... that takes data stored in QMBDataLogging__c and creates QMB_Initial_Letter__c out of it.
QMBLetteTypeToVfPage__c.getAll() suggests you could go to Setup -> Custom Settings, try to find this thing and examine. Maybe it has some values in production but in your sandbox it's empty and that's why essentially nothing works? Or maybe some values that are there are outdated?
There's some comparison if what you upload into Field1__c can be matched to what's in that custom setting. I guess you load some kind of subtype of your QMB_Initial_Letter__c in there. Record Type name and list of fields to read from your log record is also fetched from custom setting based on that match.
Then this thing takes what you pasted, looks at the list of fields in from the custom setting and parses it.
Let's say the custom setting contains something like
Name = XYZ, FieldAPINames__c = 'Name,SomePicklist__c,SomeDate__c,IsActive__c'
This thing will look at first record you inserted, let's say you have the CSV like that
Field1__c,Field2__c,Field3__c,Field4__c
XYZ,Closed,2022-09-15,true
This thing will try to parse and map it so eventually you create record that a "normal" apex code would express as
new QMB_Initial_Letter__c(
Name = 'XYZ',
SomePicklist__c = 'Closed',
SomeDate__c = Date.parse('2022-09-15'),
IsActive__c = true
);
It's pretty fragile, as you probably already know. And because parsing CSV is an art - I expect it to absolutely crash and burn when text with commas in it shows up (some text,"text, with commas in it, should be quoted",more text).
In theory admin can change mapping in setup - but then they'd need to add new field anyway to the loaded file. Overcomplicated. I guess somebody did it to solve issue with Record Type Ids - but there are better ways to achieve that and still have normal CSV file with normal columns and strong type matching, not just chucking everything in as strings.
In theory this lets you have "jagged" csv files (row 1 having 5 fields, row 2 having different record type and 17 fields? no problem)
Your call whether it's salvageable or you'd rather ditch it and try normal loading of QMB_Initial_Letter__c records. (get back to your business people and ask for requirements?) If you do have variable number of columns at source - you'd need to standardise it or group the data so only 1 "type" of records (well, whatever's in that "Field1__c") goes into each file.
I am working with spring data jpa, I would like to know in QueryByExample(QBE) can i get all the records (where colum value not equals 'XXX')
I have seen ExampleMatcher , but couldnt find anything like not equals
Employee filterBy = new Employee();
filterBy.setLastName("ar");
//Filter - ignore case search and contains
ExampleMatcher matcher = ExampleMatcher.matching()
.withStringMatcher(StringMatcher.CONTAINING) // Match string containing pattern
.withIgnoreCase(); // ignore case sensitivity
example = Example.of(filterBy, matcher);
The above code gets all the records where lastname is ar, but i am looking for lastname should not be "ar".
Is there any other ExampleMatcher ?
BizExceptionConfig condition = configRequestPair.getCondition();
ExampleMatcher exampleMatcher = ExampleMatcher.matching()
.withMatcher("appCode", startsWith())
.withMatcher("name", startsWith())
.withMatcher("code", startsWith());
if(Objects.isNull(condition.getLifecycle())){
condition.setLifecycle(LifeCycle.DELETE.getCode());
HashMap<String, Integer> params = new HashMap<>();
params.put("$ne", LifeCycle.DELETE.getCode());
exampleMatcher = exampleMatcher.withTransformer("lifecycle", (obj) -> Optional.of(params));
}
Example<BizExceptionConfig> example = Example.of(condition, exampleMatcher);
Page<BizExceptionConfig> pageRecord = bizExcConfigRepository.findAll(example, PageUtil.toPageRequest(configRequestPair.getPage()));`enter code here`
This problem can be solved by "withTransformer". JPA is rather limited,
so I suggest using Mongotmpl. I hope it can help you
Your problem could be solved with QBE by using REGEX as StringMatcher and the solution would look like the following:
Employee filterBy = new Employee();
filterBy.setLastName("ar");
filterBy.setLastName(String.format("^(?!.*$1$).*$", Pattern.quote(filterBy.getLastName())));
//filterBy.setLastName(String.format(".*(?<!$1)$", Pattern.quote(filterBy.getLastName()))); // this would be another alternative
ExampleMatcher matcher = ExampleMatcher.matching()
.withStringMatcher(StringMatcher.REGEX) // Match string containing pattern
.withIgnoreCase(); // ignore case sensitivity
Example example = Example.of(filterBy, matcher);
Unfortunately, even though the developer would at first think that Regular Expressions are supported (as there exists aforementioned enum constant), Spring actually currently doesn't support them - and according to the discussion of the related Jira issue, it never won't: https://jira.spring.io/browse/DATAJPA-944
The bizarre properties in the .NET SDK continue to baffle me. How do I read the UnitPrice from an invoice line?
If I do this:
sild = (SalesItemLineDetail)line.AnyIntuitObject;
ln = new QBInvoiceLine(); // My internal line item class
ln.Description = line.Description;
ln.ItemRef = new QBRef() { Id = sild.ItemRef.Value, Name = sild.ItemRef.name };
if (sild.QtySpecified)
ln.Quantity = sild.Qty;
else
ln.Quantity = 0;
if (sild.ItemElementName == ItemChoiceType.UnitPrice)
ln.Rate = (decimal)sild.AnyIntuitObject; // Exception thrown here
The last line throws an invalid cast exception, even though the debugger shows that the value is 20. I've tried other types but get the same exception no matter what I do. So I finally punted and am calculating the rate like so:
ln.Rate = line.Amount / ln.Quantity;
(With proper rounding and checking for divide by zero, of course)
While we're on the subject... I noticed that in many cases ItemElementName == ItemChoiceType.PriceLevelRef. What's up with that? As far as I know, QBO doesn't support price levels, and I certainly wasn't using a price level with this invoice or customer. In this case I was also able to get what I needed from the Amount property.
Try this-
SalesItemLineDetail a1 = (SalesItemLineDetail)invoice11.Line[0].AnyIntuitObject;
object unitprice = a1.AnyIntuitObject;
decimal quantity = a1.Qty;
PriceLevelRef as an 'entity' is not supported. This means CRUD operations are not supported on this entity.
The service might however be returning readonly values in the transactions sometimes, but since this not mentioned in the docs, please consider it as unsupported.
Check that both request/response are in either json or xml format-
You can use the following code to set that-
ServiceContext context = new ServiceContext(appToken, realmId, intuitServiceType, reqvalidator);
context.IppConfiguration.Message.Request.SerializationFormat = Intuit.Ipp.Core.Configuration.SerializationFormat.Json;
context.IppConfiguration.Message.Response.SerializationFormat = Intuit.Ipp.Core.Configuration.SerializationFormat.Json;
Also, in QBO UI, check if Company->sales settings has Track Quantity and Price/rate turned on.
I can send callback param(s) and it works perfectly as long as I am only sending some primitive types like String. But the same thing does not work for even the simplest POJO. PrimeFaces guide says that the RequestContext.addCallbackParam() method can handle POJOs and it coverts them into JSON. I don't know why it's not working in my case.
Has anybody done that?
Solution found! ---------------------------------------------------------------------
I did some research and found the answer to this question.
And the solution was to use some JSON library (right now I am using GSON) to convert Java objects to JSON objects.
new Gson().toJson(someJavaObj)
returns string. Just send the string as the param and on the client side using js' eval or some js library's function to turn that into JSON again.
Actually, it was pretty clean and simple.
Sorry I actually did not post the solution. Below is the my solution -
Action method in the backing bean -
public void retrievePieData() {
List<String> categories = new ArrayList<String>();
categories.add("Electronic");
categories.add("Food");
categories.add("Liguor");
categories.add("Stationary");
categories.add("Mechanical");
List<Integer> itemCounts = new ArrayList<Integer>();
itemCounts.add(5);
itemCounts.add(20);
itemCounts.add(1);
itemCounts.add(50);
itemCounts.add(10);
RequestContext reqCtx = RequestContext.getCurrentInstance();
reqCtx.addCallbackParam("categories", new Gson().toJson(categories));
reqCtx.addCallbackParam("itemCounts", new Gson().toJson(itemCounts));
}
PrimeFaces p:commandButton in the view -
<p:commandLink action="#{pieDataProvider.retrievePieData}" oncomplete="feedPieData(xhr, status, args);" value="Pie chart demo" update="pieData" />
Javascript function -
function feedPieData(xhr, status, args) {
var categories = eval('(' + args.categories + ')');
var itemCounts = eval('(' + args.itemCounts + ')');
options.xAxis.categories = categories;
var series = {
data: []
};
series.name = new Date().toString();
series.data = itemCounts;
options.series = [series];
chart = new Highcharts.Chart(options);
}
I would really appreciate and welcome any suggestion or opinion.
Thank you!
I wrote a program communicated with sockets.But I don't know why they don't work.
Server Code:
this.serverSocket = new ServerSocket(ServerConnector.port);
this.socketListener = this.serverSocket.accept();
System.out.println(this.socketListener.getPort());
this.objIn = new ObjectInputStream(this.socketListener.getInputStream());
System.out.println("1");
this.objOut = new ObjectOutputStream(this.socketListener.getOutputStream());
System.out.println("1");
this.objOut.writeInt(19999);
System.out.println("1");
this.objOut.writeObject(new Date());
System.out.println("1");
Client Code:
this.clientSocket = new Socket(ClientConnector.host, ClientConnector.port);
System.out.println(this.clientSocket.getPort());
this.objIn = new ObjectInputStream(this.clientSocket.getInputStream());
System.out.println("1");
this.objOut = new ObjectOutputStream(this.clientSocket.getOutputStream());
System.out.println("1");
int i = (Integer) this.objIn.readInt();
System.out.println(i);
Date date = (Date) this.objIn.readObject();
The truth is, they don't show any information I suggested to pass through(19999 and date), they even can't print a line of "1"(I added for testing). It means even the line below can't work normally. I really confused by these, who can figure the error out?
this.objIn = new ObjectInputStream(this.clientSocket.getInputStream());
You are most likely experiencing the effect of Nagle's Algorithm. which tries to optimize packet sending in TCP. If you want to send your data immediately you need to disable it using the setTcpNoDelay method on the socket interface.
P.S. no idea why the question is tag'ed as osgi, as it has no relevance to OSGi at all.
