int-jpa:retrieving-outbound-gateway and caching the result - spring-data

IS it possible to cache the result of jap retriving oubound gateway(int-jpa:retrieving-outbound-gateway). So that every time the query is not executed if result available in cache?

The solution with existing code base may look like:
<transformer input-channel="input" ref="testBean" method="upperCase" output-channel="output">
<request-handler-advice-chain>
<cache:advice>
<cache:caching cache="foo">
<cache:cacheable method="handle*Message" key="#a0.payload"/>
</cache:caching>
</cache:advice>
</request-handler-advice-chain>
</transformer>
It is <transformer> here, but the same is applied for the JPA gateway as well.
Pay attention to the method="handle*Message" AOP path.
Plus the key expression is based on the Message as a0 cacheable Advice argument.
That's may be why we still don't support it as out-of-the box component in Spring Integration. Pretty simple and straightforward solution.

This is not currently provided by the framework, but you can easily add a custom advice to the outbound gateway to implement this mechanism.

Protractor Implementation in Angular2 without using ids

I have application in Angularjs2, and developers have not been using ids into it. Now I have to implement the Protractor on same application. Is there anyway to implement the Protractor without using "absolute XPath"?
Thanks in advance!
Please find a huge range of locator-possibilities on the official Protractortest API Page
Every element on a page needs to be uniquely identifiable... else the page wouldn't work, no matter which technology. Therefore with the help of any of the above provided locator-possibilities you'll always find the element you're looking for.
And there is never a need for XPath, except for this only one. (though there is an parentElementArrayFinder introduced in the meantime, so not even that one exception is valid anymore)
UDPATE
If you could use XPath, you can for sure use CSS-Locators.
Here some examples for locators:
$('div.class#id[anyAttribute="anyValue"] div.child.somewhere-below-div-point-class')
element(by.cssContainingText('div[data-index="2"]', 'select this option'))
Or as a specific example the "Learn More" of the "Tree List" section of https://js.devexpress.com/ :
treeListSection = element(by.cssContainingText('div.tab-content h2', 'Tree List')).getDriver();
learnMoreBtn = treeListSection.element(by.cssContainingText('a.tab-button','Learn More'));
learnMoreBtn.click();
Those are just examples, but there is always a way to do it.
If you provide some example-HTML in your Question, I can direct you towards a solution.
UPDATE 2
For getting the Parent Web Element, one could use getDriver() as well

Custom Search Results in REST MarkLogic

So new to MarkLogic am stuck and not finding the documentation of use. I know what i need to do, just do not know how to do it.
I have a keyvalue? search on my REST server which returns ML's standard search results and XML snippet. I want to create my own custom search result which will output a title element for my XML files.
I am aware that i need to create an XSLT transformation document and upload that to the server but do not know how to target ML's search function or how to write this out.
I have basic knowledge of XSLT, if i just created something that targets each files title using xPath will this work, or does ML require use of their custom functions?
I know its a bit broad, but hopefully someone can point steer me.
Sounds like you are talking about the GET /v1/keyvalue endpoint of MarkLogic REST API. Unfortunately that does not allow you to choose a transform. You can probably use GET /v1/search with a transform param instead though, using a structured query for an element value query. The docs contain a good syntax reference on that.
Docs on creating and managing transforms can be found here:
http://docs.marklogic.com/guide/rest-dev/transforms#chapter
HTH!
You can use extract-metadata in your search options with search:search or the /v1/search/ REST API endpoint to include the title element in a metadata element or JSON property in your results:
import module namespace search = "http://marklogic.com/appservices/search"
at "/MarkLogic/appservices/search/search.xqy";
search:search(
"my query string",
<options xmlns="http://marklogic.com/appservices/search">
<extract-metadata>
<qname elem-ns="" elem-name="title"/>
</extract-metadata>
</options>)
If you need more flexibility, you specify a custom snippet implementation or a results decorator function in your search options.
Is this key-value or full text? For key-value you could use XPath. Any XPath that starts with / or // or fn:collection() or fn:doc() will search the entire database. You can search specific document(s) or collection(s) too.
For full text you'd probably want to use https://docs.marklogic.com/search:search - or possibly https://docs.marklogic.com/cts:search for really low-level control.
There's some example code using search:search from XSL at https://github.com/marklogic/RunDMC which might help. It doesn't use the REST API: it's a traditional form-submit web page. But the view/search.xsl code might give you some idea how to call the search API from XSLT.
That RunDMC code might also help you if you need to call XSL from XQuery: take a look at controller/transform.xqy.

RESTful urls for restore operation from a trash bin

I've been implementing a RESTful web service which has these operations:
List articles:
GET /articles
Delete articles (which should remove only selected articles to a trash bin):
DELETE /articles
List articles in the trash bin:
GET /trash/articles
I have to implement an operation for restoring "articles" from "/trash/articles" back to "/articles".
And here is the question. Ho do you usually do it? What url do I have to use?
I came up to the 2 ways of doing it. The first is:
DELETE /trash/articles
But it feels strange and a user can read it like "delete it permanently, don't restore".
And the second way is
PUT /trash/articles
Which is more odd and a user will be confused what this operation does.
I'm new to REST, so please advice how you do it normally. I tried to search in google but I don't know how to ask it right, so I didn't get something useful.
Another option could be to use "query params" to define a "complementary action/verb" to cover this "special condition" you have (given that this is not very easily covered by the HTTP verbs). This then could be done for example by:
PUT /trash/articles?restore=true
This would make the URI path still complaint with REST guideline (referring to a resource, and not encoding "actions" - like "restore") and would shift the "extra semantics" of what you want to do (which is a very special situation) to the "query parameter". "Query params" are very commonly used for "filtering" resources in REST, not so much for this kind of situation... but maybe this is a reasonable assumption given your requirements.
I would recommend using
PUT /restore/articles
or
PUT /restore/trash/articles
Late answer but, in my opinion, the best way is to change the resource itself.
For instance:
<article is_in_trash="true">
<title>come title</title>
<body>the article body</body>
<date>1990-01-01</date>
</article>
So, in order to remove the article from Trash, you would simple use PUT an updated version of the article, where is_in_trash="false".

Replace éàçè... with equivalent "eace" In GWT

I tried
s=Normalizer.normalize(s, Normalizer.Form.NFD).replaceAll("[^\\p{ASCII}]", "");
But it seems that GWT API doesn't provide such fonction.
I tried also :
s=s.replace("é",e);
But it doesn't work either
The scenario is I'am trying to générate token from the clicked Widget's text for the history management
You can take ASCII folding filter from Lucene and add to your project. You can just take foldToASCII() method from ASCIIFoldingFilter (the method does not have any dependencies). There is also a patch in Jira that has a full class for that without any dependencies - see here. It should be compiled by GWT without any problems. License should be also OK, since it is Apache License, but don't quote me on it - you should ask a real lawyer.
#okrasz, the foldToASCII() worked but I found a shorter one Transform a String to URL standard String in Java

Remote stream multiple files in SOLR

I want to use SOLR's remote-streaming facility to extract and index the content of files.
This works fine if I pass stream.file=xxx as a parameter to the http GET method.
However, I have a lot of these, and want to batch them up (i.e. not have to have a GET per file).
Is there a way I can do this in SOLR?
e.g. I'd like to be able to POST some xml like this:
<add>
<doc stream_file="filename">
<field name="id">123</field>
</doc>
<doc>...
This has been recently asked (and answered) in the solr-user mailing list.
I find that multiple ADDs are fast, so long as you only COMMIT the batch and don't try to COMMIT after every ADD. I would guess that the performance penalty is not worth writing your own RequestHandler.
