  • how to create an excel file in google app engine (java)?

    - by Joseph
    A question that seems to have quite a few options for Python, but none for Java after googling for two days. Really really could use some help all I have found so far is a recommendation to use gaeVFS to build an excel file from the xml components and then zip it all together which sounds like a slap in the face. Oh yes and if you were wondering I am questioning my use of Java rather than python but at 5,000 lines of code it would be insane to turn back now... Other things you might find useful Client: GWT Server: Servlets running on google app engine storing data into the google data store Excel file: mandatory, CSV isn't good enough, no need to save the file just to be able to "serve" it to the client i.e. open a "Save As" box.

  • How do I use Google's Gson API to deserialize JSON properly?

    - by FK82
    Hi, In short, this is a sketch of the JSON object I want to parse in JAVA: { object1: { item1: //[String | Array | Object] , item2: // ... //<> more items object2: { // } //<> more objects } These are the POJO s I created for parsing (I'll leave out the import statements for brevity's sake): (1) The representation of the complete JSON object public class JObjectContainer { private List<JObject> jObjects ; public JObjectContainer() { // } //get & set methods } (2) The representation of the nested objects: public class JObject { private String id ; private List<JNode> jObjects ; public JObject() { // } //get & set methods } (3) The representation of the items: public class JNode { private JsonElement item1 ; private JsonElement item2 ; //<> more item fields public JNode() { // } //get & set methods } Now, creating a Gson instance (FileReader for importing the jsonFile), Gson gson = new Gson() ; JObjectContainer joc = gson(jsonFile,JObjectContainer.class) ; I get a NullPointerException whenever I try to access the parseable object (e.g. through a ListIterator). Gson does however create an object of the class I specified and does not throw any subsequent errors. I know that this has been done before. So, what am I missing? TIA

  • Twitter api - no more than 150 requests per hour....

    - by RenegadeAndy
    Hi. I am writing a twitter app using jtwitter - and its running inside a server inside my work. Anyway - whenever i run it from work it returns the error below and I am only making a couple requests per hour: HTTP/1.1 400 Bad Request {"request":"/1/statuses/user_timeline.json?count=6&id=cicsdemo&","error":"Rate limit exceeded. Clients may not make more than 150 requests per hour."} ] 2010-06-03 18:44:49 zero.timer.TimerTask::run Thread-3 SEVERE [ CWPZA3100E: Exception during processing for timer task, "twitterTimer". Exception: java.lang.ClassCastException: winterwell.jtwitter.Twitter$Status incompatible with java.lang.String ] I run the same code from home - its fine. So obviously at some point twitter thinks our work is all coming from one direct IP - which is why its hitting a limit which it shouldnt. Do I have any choice or workaround - can i make the limit be counted from my direct machine IP - or to my account instead of IP? Can i use a proxy? Has any body else had this problem and solved it?! Before anyone asks the APP must live inside my work - it cannot run anywhere else! Cheers, Andy

  • Is there a way to send a blog post to wordpress via an api?

    - by Yuval Cohen
    In more details: I want to build a web service to which users register and by browsing my site, users can send blog posts to their own blogs. Initially wordpress.org is discussed. However, I'll be happy to hear solutions for typepad or wordpress.com as well. The ideal solution would be a way for my server to simply "tell" their blog what to post (as a draft of course for them to confirm). A good solution would be for my users to install a plugin in their blog that will allow my server the above functionality. Lacking any other solution, I would give my users text to copy-paste into their blog editor. Help me find a solution and feel free to be creative!

  • How to set breakpoint in inline Javascript in Google Chrome browser for linux?

    - by Alan McCloud
    When I open Developer Tools in Google Chrome, I see all kinds useless crap like Profiles, Timelines, not to mentions Audits but basic functionality like being able to set breakpoint both in js files and within html javascript code is missing!. I tried to use javascript Console which itself is buggy ( like when once it encounter JS error, cannot get out of it unless refresh the whole page useless when ajax is involved). I am surprised google engineers still have not figured this out if these features still not available. If they are and there is some twisted way to do this, can some one help?

  • Is there a way to send tracking info to Google Analytics from PHP ?

    - by seatoskyhk
    I have a PHP code that will return a image. the link is given to 3rd party. so, i need to keep track where the php request coming from. Because the PHP only return the image, I cannot use the Javascript code for Google analytics. I know that I can get the information from the access.log, but i think I can't dump the access.log to GA for analyzing, right? so, is there a way that I can do in PHP (e.g. sending a CURL ), send somethig to Google Analytics for tracking?

  • Has Google introduced a system that allows multiple "keyword-only" domains per site?

    - by tags2k
    I've been told by a client that "a friend" told them that as of January 2010, Google allows multiple domain names that have keywords in them to be associated with a single site. To be honest this sounds rather April-foolish but I'm not sure when his "friend" told him so for the time being I have to take it at face value. I've heard nothing of this and have searched for such a thing this morning, to find nothing but warnings against this practice. Said client seems keen on buying up lots of domains today, so before he insists upon it I just want to be absolutely sure - has Google silently introduced such an allowance, or is there something else they introduced earlier this year that he could be getting confused with? Thanks for any light you can shine on this!

  • Google Chrome does not honor cache-policy in page header if the page is displayed in a FRAME

    - by Tim
    No matter what I do: <meta http-equiv="Cache-Control" content="no-cache" /> <meta http-equiv="Expires" content="Fri, 30 Apr 2010 11:12:01 GMT" /> <meta http-equiv="Expires" content="0" /> <HTTP-EQUIV="PRAGMA" CONTENT="NO-STORE" /> Google Chrome does not reload any page according to the page's internal cache policy if the page is displayed in a frame. It is as though the meta tags are not even there. Google Chrome seems to be ignoring these tags. Since I've gotten answers to this question on other forums where the person responding has ignored the operative condition, I will repeat it: this behavior occurs when the page is displayed in a frame. I was using the latest released version and have since upgraded to 5.0.375.29 beta but the behavior is the same in both versions. Would someone please care to confirm one way or another the behavior you are seeing with framesets and the caching/expiration policies given in meta tags? Thanks

  • Paypal API for preapproved payments , is the merchant charged for pre-approved transactions ?

    - by Michael
    I'm running an classified ads website and I'm charging a specific fee for each ad placed. As you may know paypal charges a specific percent for each transaction + a specific amount fee (e.g 2,9% + 0.30 cents) . I have customers who place about 30 ads per month therefore I would like to integrate a schema that would cut the specific amount fee . Basically I'm looking to make "pre-approve" call every time after the client place an ad to make sure that he has the money to pay and at the end of the month to cancel all the scheduled pre-approved transactions and make a single payment request with the whole amount. The question that I have is : Will I be charged for the pre-approved transactions that I cancel ?
