I need to call a rest web service in playframework 2 and I need to send a query parameter which is an array. In regular html I would send it like:
GET http://host.com?a=1&a=2&a=3
But when I do it when I try to do it with the playframework 2 WS api I do the next:
Map<String,String[]> paramMap = new HashMap<String, String[]>();
paramMap.put("a",new String[]{"value1","value2"});
WS.WSRequestHolder holder = WS.url("http://host.com");
Set<String> keys = paramMap.keySet();
for (int i = 0; i < paramMap.get(key).length; i++)
{
holder.setQueryParameter(key, paramMap.get(key)[i]);
}
And the first time that setQueryParamater() arrives, everything goes perfect but the second time I get a NullPointerException and paramMap.get(key)[i] is not null. Is this possible? is there any workaround?
Thanks in advance!
In regular html you need to dsend it like:
GET http://host.com?a=1&a=2&a=3
Using ampershand(&) to separate parameters in query string instead of comma(,)
Edit: Sorry forgot to type: Like ur trying to do within the loop you should not have fields with same name. You should change it as:
http://host.com?a1=value1&a2=value2
I don't know if this causes NullPointerException you face. But even if does not i suggest you change ur implementation to keep one value per field (key, value)
Ok, it seems to be a bug in play-framework, but solved in 2.1 version.

I am new to Polymer 2.0. I need to update a field called Print Name to set the values I put in First Name + Last Name. Currently I get a version of it that is not working as I get bad request. 'System.FormatException: Input string was not in a correct format.'
_updateField(e) {
e.preventDefault();
this.set('_contract.signeeContact.printName', [this._contract.signeeContact.firstName, this._contract.signeeContact.lastName]);
// printName: ["firstName", "LastName"] // this is not correct it should be
// printName: ["firstName LastName"] // correct request should look like this
}
the format is not correct. Can someone give me a hand with this?
Thank you in advance.
Please could somebody confirm the following..
I am using Mirth Connect 3.5.08232.
My Source Connector is a Database Reader.
Say, I am using a query that returns multiple rows, and return the result (via JavaScript), as documentation suggests, so that Mirth would treat each row as a separate message. I also use a couple of mappers as source transformers, and save the mapped fields in my channel map (which ends up to contain only those fields that I define in transformers)
In the destination, and specifically, in destination response transformer (or destination body, if it is a JavaScript writer), how do I access the source fields?
the only way I found by trial and error is
var rawMsg = connectorMessage.getRawData();
var xmlMsg = new XML(rawMsg);
logger.info(xmlMsg.some_field); // ignore the root element of rawMsg
Is this the right way to do this? I thought that maybe the fields that were nicely automatically detected would be put in some kind of a map, like sourceMap - but that doesn't seem to be the case, right?
Thank you
If you are using Mapper steps in your transformer to extract the data and put it into a variable map (like the channel map), then you can use any of the following methods to retrieve it from a subsequent JavaScript context (including a JavaScript Writer, and your response transformer):
var value = channelMap.get('key');
var value = $c('key');
var value = $('key');
Look at the Variable Maps section of the User Guide for more information.
So to recap, say you're selecting a column "mycolumn" with a Database Reader. The XML sent to the channel will be something like this:
<result>
<mycolumn>value</mycolumn>
</result>
Then you can choose to extract pieces of that message into specific variables for later use. The transformer allows you to easily drag-and-drop pieces of the sample inbound message.
Finally in your JavaScript Writer (or in any subsequent filter, transformer, or response transformer), just drag the value into the field you want:
And the corresponding JavaScript code will automatically be inserted:
One last note, if you are selecting a lot of variables and don't want to make Mapper steps for each one individually, you can use a JavaScript Step to iterate through the message and extract each column into a separate map variable:
for each (child in msg.children()) {
channelMap.put(child.localName(), child.toString());
}
Or, you can just reference the columns directly from within the JavaScript Writer:
var msg = new XML(connectorMessage.getEncodedData());
var column1 = msg.column1.toString();
var column2 = msg.column2.toString();

I am trying to find the max changestamp so I can start using it. I tried the following:
URL url = "https://docs.google.com/feeds/default/private/changes?v=3"
ChangelogFeed foo = service.getFeed(url, ChangelogFeed.class);
LargestChangestamp stamp = foo.getLargestChangestamp();
stamp is always null.
Is this the way to get the largest changestamp, or do I need to set it first in order to use it?
The largest changestamp is also available in the user metadata feed. See the "docs:largestChangestamp" element within the response protocol tab here,
I'm not sure the java api exposes the largestChangestamp property directly yet - last time I checked it was hidden in the xmlBlob property, and I had to do an xml parse to grab it out.
This seems to be a bug in the API. I got the changestamps by getting the ChangelogEntrys from the ChangelogFeed:
List<ChangelogEntry> entries = foo.getEntries();
for (ChangelogEntry entry: entries) {
String blob = entry.getXmlBlob().getBlob();
System.out.println("Blob: " + blob);
}
The changestamp for an entry is contained in its blob.
I have a problem using JIRA SOAP client. When I use RemoteIssue.getResolution() or RemoteIssue.getStatus() I get number values. For example let say we have an issue that has resolution = fixed. When I call client.getIssueFromJqlSearch(token, "issuetype = Bug AND resolution = fixed", 10) this will return an array of type RemoteIssue[]. Now if I call issues[i].getResolution() (where issues[] is the result from previous call getIssuesFromJqlSearch) this will return a value "5" instead of "fixed". How to solve this? Is there any way to get the value "fixed" for that issue and not a custom value "5"?
Thank you in advance.
If you call getResolutions() on the SOAP API you'll get an array of all the resolutions defined in the instance, including their Ids. You can then use this to work out which resolution the Id you've got refers to.
Looking at the source code of Action.Submit, I'm trying to figure out where ext is appending the form's fields to the parameters.
Instead of sending each field as a separate parameter, I want to send something like:
formObj:{field1:value, field2:value}
Currently, each of those values are simply added to the parameter list along with any custom/baseParams.
Where are these formfields being added so that I can change this behaviour?
Thanks.
I'm not sure what your override needs to look like, but you'll probably want to look at Ext.Ajax.request() (in Core / Connection.js). When posting a form, the fields get serialized there, in this code block:
if(form = Ext.getDom(o.form)){
url = url || form.action;
serForm = Ext.lib.Ajax.serializeForm(form);
p = p ? (p + '&' + serForm) : serForm;
}
If you really want to track the process of creating parameter list, you can refer to Ext.form.Action.getParams.
You should also consider Ext.form.BasicForm.getValues as it returns exactly the result you want, the only problem is that you'll need to send it manually, e.g. using Ext.Ajax.request.
