Generating Java code from transformation JSON to a XML

I wonder do you now any program that can generate for me a Java code from transformation JSON to a XML? In Altova MapForce there is such a possibility, but unfortunately when I want use it, it returns me an Error:
Altova_Hierarchical_JSON.mfd: Mapping validation failed - 1 error(s), 0 warning(s)
Altova_Hierarchical: JSON components are not supported for Java.
The output component Altova_Hierarchical has no output file name set. A default file name will be used.
The second thing, that is important for me, is capabilities to create graphic mapping between JSON and XML like example below shows:
Thanks for the reply.

There is underscore-java library with static method U.xmlToJson(xml). I am the maintainer of the project.
<anyxml>data</anyxml>
Output:
{
"anyxml": "data",
"#omit-xml-declaration": "yes"
}

get all values using get paremeters in java

I'm passing the some values url from flex to java example:
URL format:
../mahesh/initUser.do?method=fwdAccDetails&securityId=mUuB3/p/ky5JhZPY5T8Znf01YCcIarIalQiGEXPMMsOkWDX+KtT4fx2gMML+uup8
After I'm tiring to get "securityId" values in java like
request.getParameter("securityId")
But I'm getting following values only
mUuB3/p/ky5JhZPY5T8Znf01YCcIarIalQiGEXPMMsOkWDX KtT4fx2gMML uup8
symbol getting empty space in java side..
Here is my Flex code:
navigateToURL(new URLRequest('../mahesh/initUser.do?method=fwdAccDetails&securityId='+value+'),'_s‌​elf');
I didn't get full values.. any one can help me how I will get correct values in Java..

You should use the encodeURIComponent()-Function to properly encode your securityId.
value = encodeURIComponent(value);
navigateToURL(new URLRequest('../mahesh/initUser.do?method=fwdAccDetails&securityId='+value+'),'_s‌​elf');
That way your String will be correct on the Java side.
If you want to read more about proper escaping, have a look at When are you supposed to use escape instead of encodeURI / encodeURIComponent? (Same arguments apply for Flex and JavaScript).

i just resolve my issue for following code in a javURLDecoder.decode(param1AfterEncoding.replace("+", "%2B"), "UTF-8").replace("%2B", "+")
Now its working fine only.. i dint other special character will work fine.. i will check it later..

Velocity - How to avoid ParseErrorException when using jQuery?

I'm trying to add a jQuery post to some JavaScript on a web page. The entire page is built up of several Velocity templates. Everything has been fine until I've tried to add the jQuery post, now I get:
org.apache.velocity.exception.ParseErrorException: Encountered "," at line 282, column 24 of /WEB-INF/velocity/www/comments.vm
Was expecting one of:
"(" ...
<RPAREN> ...
<ESCAPE_DIRECTIVE> ...
~~~snip~~~
Line 282 is $.post(... and column 24 appears to be the first "," character. Initially I had the JSON on this line, but I moved it up (to the var myJSONObject ... line)as I thought the error related to invalid JSON (tabs at the start of the line gave a misleading column number).
var myJSONObject = {"body": "", "action": "postcomment", "submitted": "true", "ajax": "true"};
myJSONObject.body = $("body").val();
$.post("$!{articleurl}", myJSONObject, function(result){
btn.textContent='Comment sent successfully.';
});
Minor Update
I changed the following lines:
var url = "$articleurl";
$.post(url, myJSONObject, function(result){
~~~snip~~~
The parse exception still focuses on the first ",". I'm assuming the issue is that Velocity thinks it should be able to resolve $.post - when in fact, it's jQuery. I've used jQuery in other Velocity VM templates without any problem. Is there a way to get Velocity to ignore certain lines / statements when parsing?
Update 2
I found this link about escaping references in Velocity, but it does not resolve my issue. Adding a "\" before $.post gives me the exact same error, but the column is one extra, because of the character added at the start of the line.

You can wrap your javascript with #[[ ... ]]# which tells Velocity to not parse the enclosed block (new in Velocity 1.7)
#[[
<script>
...
</script>
]]#

Ok, there appears to be two solutions for this:
First, with jQuery we can just avoid using the global alias $ and instead use the jQuery object directly:
jQuery.post(url, myJSONObject, function(result){
~~~snip~~~
In my case, the above works great. But I suspect in other scenarios (non-jQuery) this may not be possible. In which case, we can 'hide' our character within a valid Velocity reference like this:
#set( $D = '$' )
${D}
Source: http://velocity.apache.org/engine/devel/user-guide.html#escapinginvalidvtlreferences
I'd still like to know why the backslash escape didn't work, but the above will at least get me moving again. :)

I think this is a bug in version 1.6.x, because it works fine in 1.7(If it did not, please tell me, I test it many times..), according to the reference, the $ takes effect only when it is followed by a-zA-Z. I want to try do debug what happened really, but the translation code is generated by Java CC tool, it is too hard to recognize the logic...

you must create a js file with your javascript code
and import your js file into your vm code

I couldn't get it to work with any of the other fixes like escaping "$" in velocity unfortunately. I got it working by loading an external js-file with the jQuery instead of writing jQuery directly in velocity. Worked out for me at least, hope it helps someone :)

Converting HTTP Response (Java "Properties" stream format) in to NSDictionary

I am working on iphone application which contains HTTP Request and Response.
The format of the response is a key/value format compatible with the Java "Properties" stream format.
I want to store the response into a NSDictionay. Could you suggest me any way to do this?
Thank you.
sangee
Edit:
Thanks guyz for the quick replies!!!
is their any other ways to store them in NSSdictionay?
I just want to store the album name and description in an array like this:
mutablearray = [wrwr, dsf, my album];
could you please let me know if this possible or not?
Thanks again!!!
This is the response i got it for my HTTP request...

If you can, I would recommend serializing the data as JSON (or XML, if you have to) and parsing it using TouchJSON or a similar parser. If you really can't, then you'll have to implement your own parser--take a look at NSScanner.

Look at NSStream and the Stream Programming Guide for Cocoa.
Back in the day when Java was fully integrated into Cocoa, NSStream mapped onto Java streams. It still might. IIRC, (it's been a while) NSStream will return a properly populated NSDictionary from a Java stream.
Edit:
It looks like the text returned is just a space delimited hash which is the Java version of dictionary. It takes the form of key=value space key=value. The only tricky part is that some of the hashes are nested.
The first line for example is nested:
debug_album{
debug_gallery_version{
debug_user=admin
debug_user_type=Gallery_User
debug_user_already_logged_in{
server_version=2.12
status=0
status_text=Login successful.
}
}
}
You need a recursive scanner to parse that. The "key=space" pattern indicates a nested dictionary.

Changing Encoding while Xml.parse() with SaxFeedParser Java

I am trying to load hebrew rss using the fllow :
Xml.parse(_InputStream, Xml.Encoding.ISO_8859_1 , root.getContentHandler());
taken from ibm site :
link text
I would like to use other Encoding like "ISO8859_8" rather than :
Xml.Encoding.ISO_8859_1,
Xml.Encoding.US_ASCII,
Xml.Encoding.UTF_16,
Xml.Encoding.UTF_8
Thanks a lot!

you can't, because Xml.Encoding is an enum. you'll have to use one of the other methods, or -- if you can -- get the RSS feed producer to output UTF-8.
