Php Encode - Java Decode (URL parts)

Question

I have code where an url is decoded in php. Then parts from it are used to create a String containing Key-Value-Pairs (like Param=EncodedPartOfUrl&Param2=EncondedPartofUrl&...) with (urlencode)

Now I want to decode it in Java. Can I use the URLDecoder for it or might there be a incompatibility? I also guess that in PHP there is no encoding scheme specified (when I understand the docs correctly) - how do I solve this then in java? Don't use a specified econding scheme (which is deprecated in Java 6 for URLDecoder)?

So this is not a java web application you're working with? A java SE(desktop) application then? — ChadNC

no, it is not a webapplication. Its simply a java program working with data and generating more data as output. ;-) — nano7

in that case please provide some code of how you're trying to do this so that someone may be able to help you. — ChadNC

Can't You just build Your URL, then url_encode it in PHP and then use Your URLDecoder in Java (or whatever it is)?

URL encoding just of values from Key-Value pairs is not enough and not quite good approach - You should URL encode the whole URL for this...

EDIT:

Thanks for your answer, but I have no influence there. I can only work on the java side of code.

Then You have the only possibility: parse the URL to get the GET parameters and URL decode each of their values separately...

Thanks for your answer. thats what I thought. I parse the Parameters and then I decode. The question is, are there incompatibilities? What about the encodign scheme?

@nano7 If they use url_encode() on PHP side there should be no incompatibility as it preserves HTTP standards.

They use urlencode(), but I thought this creates platform specific results. In Java I can decide wether I use a specific encoding scheme or not. If I use an encoding scheme, maybe I would create wrong decoded results ? Not using an encoding scheme means using a deprecated method,,,

Then I am sorry cos I do not see into the Java UrlDecoder and cannot ell You whether there will be incompatibilities or not... You can only try and You'll see...
