In my JMeter project I make a request and I get a response like {id="fklajdlfja"} and then I get one JSON file for each response.
My question is, is there an elegant way to merge all the ids in a file?
My options are:
Make a JavaScript after using JMeter to put all together.
A JSON post-processor to get the id and then append to a file
Any nicer solution?
Extract the id from response, you can either use regular expression extractor or json post processor.
Use Beanshell Post processor and append these id's into a file. That should be easiest way.

I have a JSON that looks more or less like this:
{"id":"id","date":"date","csvdata":"csvdata".....}
where csvdata property is a big amount of data in JSON format too.
I was trying to POST this JSON using AJAX in Play! Framework 1.4.x so I sended just like that, but when I receive the data in the server side, the csvdata looks like [object Object] and stores it in my db.
My first thought to solve this was to send the csvdata json in string format to store it like a longtext, but when I try to do this, my request fails with the following error:
413 (Request Entity Too Large)
And Play's console show me this message:
Number of request parameters 3623 is higher than maximum of 1000, aborting. Can be configured using 'http.maxParams'
I also tried to add http.maxParams=5000 in application.conf but the only result is that Play's console says nothing and in my database this field is stored as null.
Can anyone help me, or maybe suggest another solution to my problem?
Thanks you so much in advance.
Is it possible that you sent "csvdata" as an array, not a string? Each element in the array would be a separate parameter. I have sent 100KB strings using AJAX and not run into the http.maxParams limit. You can check the contents of the request body using your browser's developer tools.
If your csvdata originates as a file on the client's machine, then the easiest way to send it is as a File. Your controller action would look like:
public static void upload(String id, Date date, File csv) {
...
}
When Play! binds a parameter to the File type, it writes the contents of the parameter to a temporary file which you can read in. (This avoids running out of memory if a large file is uploaded.) The File parameter type was designed for a normal form submit, but I have used it in AJAX when the browser supported some HTML5 features (File API and Form Data).
I am integrating data between two systems using Apache Camel. I want the resulting xml to be written to an xml file. I want to base the name of that file on some data which is unknown when the integration chain starts.
When I have done the first enrich step the data necessary is in the Exchange object.
So the question is how can I get data from the exchange.getIn().getBody() method outside of the process chain in order to generate a desirable filename for my output file and as a final step, write the xml to this file? Or is there some other way to accomplish this?
Here is my current Process chain from the routebuilders configuration method:
from("test_main", "jetty:server")
.process(new PiProgramCommonProcessor())
.enrich("piProgrammeEnricher", new PiProgrammeEnricher())
// after this step I have the data available in exchange.in.body
.to(freeMarkerXMLGenerator)
.to(xmlFileDestination)
.end();

The file component takes the file name from a header (if present). So you can just add a header to your message with the desired file name.
The header should use the key "CamelFileName" which is also defined from Exchange.FILE_NAME.

I am using the Selenium 2 Java API to interact with web pages. My question is: How can i detect the content type of link destinations?
Basically, this is the background: Before clicking a link, i want to be sure that the response is an HTML file. If not, i need to handle it in another way. So, let's say there is a download link for a PDF file. The application should directly read the contents of that URL instead of opening it in the browser.
The goal is to have an application which automatically knows wheather the current location is an HTML, PDF, XML or whatever to use appropriate parsers to extract useful information out of the documents.
Update
Added bounty: Will reward it to the best solution which allows me to get the content type of a given URL.
As Jochen suggests, the way to get the Content-type without also downloading the content is HTTP HEAD, and the selenium webdrivers does not seem to offer functionality like that. You'll have to find another library to help you with fetching the content type of an url.
A Java library that can do this is Apache HttpComponents, especially HttpClient.
(The following code is untested)
HttpClient httpclient = new DefaultHttpClient();
HttpHead httphead = new HttpHead("http://foo/bar");
HttpResponse response = httpclient.execute(httphead);
BasicHeader contenttypeheader = response.getFirstHeader("Content-Type");
System.out.println(contenttypeheader);
The project publishes JavaDoc for HttpClient, the documentation for the HttpClient interface contains a nice example.
You can figure out the content type will processing the data coming in.
Not sure why you need to figure this out first.
If so, use the HEAD method and look at the Content-Type header.
You can retrieve all the URLs from the DOM, and then parse the last few characters of each URL (using a java regex) to determine the link type.
You can parse characters proceeding the last dot. For example, in the url http://yoursite.com/whatever/test.pdf, extract the pdf, and enforce your test logic accordingly.
Am I oversimplifying your problem?
I have a JSP in which I want to:
make an HTTP request;
get back the XML response;
transform the response using XSL; and
export the transformed data to excel.
But i do not get the entire data in a single HTTP call. Also I have to use two stylesheets for exporting to Excel. The first is for the first page of records, and the other is for all the other pages.
How can one do this in Java?
Thanks
Or use Apache POI, its a powerful API to read and create MS Office documents in Java.
Could you parse the XML into Java objects, then when you have the complete object list simply write the Excel file using JExcelAPI? I've used this for Excel files and it's very simple & useful.
i have html form with textarea in which i paste some XML, for example:
<network ip_addr="10.0.0.0/8" save_ip="true">
<subnet interf_used="200" name="lan1" />
<subnet interf_used="254" name="lan2" />
</network>
When user submit form, that data is send to Java server, so in headers i get something like that:
GET /?we=%3Cnetwork+ip_addr%3D%2210.0.0.0%2F8%22+save_ip%3D%22true%22%3E%0D%0A%3Csubnet+interf_used%3D%22200%22+name%3D%22lan1%22+%2F%3E%0D%0A%3Csubnet+interf_used%3D%22254%22+name%3D%22lan2%22+%2F%3E%0D%0A%3C%2Fnetwork%3E HTTP/1.1
how can i use that in my Java applications? I need to make some calculations on that data and re-send new generated XML.
This answer shows how to use the URLDecoder/URLEncoder classes to decode and encode url strings. It should work if you passed the 'GET' string to the URLDecoders decode method.
To answer your following question (comment)
First you need to extract this xml based response from the url string. Maybe it's enough to create a substring starting with the first < char.
The String should be fed into a XML parser to create a DOM document. The last easy task would be walking through that document and copying the values to your internal network model.
Do not think about using RegExp to extract the data. Use a parser.
