How to read and write XML files and treat the comment nodes as text nodes in Java when saving
(1 answer)
Closed 3 years ago.
I am desperately looking for a library or snippet to convert a XML Node into a string representing the Node element.
I only find String > XML guides. I found the Spring Shell library XmlUtils which had that functionality (in version v1.0.0.M1) but was broken due transient dependencies and therefore not possible to be used.
I also found Apache XMLUtils which have a similar functionality. Sadly the lib seems to be not maintained for more than 8 years or such. I am unsure to use it because of that.
EDIT: I found this one as the actual XMLUtils from Apache Axis2: https://mvnrepository.com/artifact/org.apache.axis2/axis2-kernel/1.7.9
But as I can see in the doc the wanted method has been removed (https://axis.apache.org/axis2/java/core/apidocs/org/apache/axis2/util/XMLUtils.html)
Did I missed something? Every Utils library I found has removed the functionality of converting an Element/Node into a String XML.
Am really in need of a good advice for the mentioned problem.

Deserialize json to java using jackson - issues with special characters
(1 answer)
Closed 4 months ago.
I have a JSON name value pair which I would like to convert to a Java object.
The JSON is as follows
{
"x5t#S256": "vaule",
}
The below does not work because of illegal character
public class Key {
#JsonProperty
private String x5t#S256;
}
As you might guess this has to do with JWKS sets, but that's not relevant for now. It seems like quite straightforward question, but I have not been able to find anything on google.
You can pass the original name into the annotation, and give a different name to your attribute, for example:
#JsonProperty("x5t#S256")
private String differentName;

How to parse JSON in Java
(36 answers)
Closed 9 months ago.
so I have, I doing a program that receives a string json with an unknown structure (since it's a variable each time I receive a new one) and it needs to parse the string to extract each key and its type (from its value).
I need to do this using only java (no spring) because I've seen solution using Jackson tree, but with the software I'm using it impossible
If someone could help I would appreciate it.
You can use JSONObject from org.json library .

Deserializing a java serialized file in C#
(3 answers)
Closed 6 years ago.
I have a very old Java application that I am rewriting in .net, I can't change the Java code or the old files in any way.
They have created and stored 10,000+ files that match the format described in this article, a bunch of serialized Java objects.
Question
How can I parse these Java objects in c#?
Is this even possible?
In the end, if I can read in and serialize the data, I can store it in a more universal format. When I try to deserialize the file I reach an exception, usually telling me the binary format is not valid.
A similar question has been asked here.
You have a few options. One is to write a C# class capable of reading objects in Java's serialized format (the one you linked) but this is likely very time consuming. Using C#'s native deserialization algorithm won't work because the format is different (as you've encountered).
An easier alternative is to read the objects from the files using a Java program, and save them as a more universal format such as JSON. (As recommended in an answer to another question here)

Java : parse java source code, extract methods
(2 answers)
Closed 7 years ago.
I am working on a small program to compare two Java files. My goal is to compare the two files so that I can see what functions were added and deleted from one file to another (like a simple version control program). I am running into issues on how I should be handling these files. My current approach is to use a Scanner and use:
while(scanner.hasNext()) {
String function = scanner.next("((public|private|protected|static|final|native|synchronized|abstract|threadsafe|transient)+\\s)+[\\$_\\w\\<\\>\\[\\]]*\\s+[\\$_\\w]+\\([^\\)]*\\)?\\s*\\{?[^\\}]*\\}?");
System.out.println(function);
}
However this is not getting me any results for a file that I know has functions in it. Any tips or ideas on how to approach this?
You could use ANTLR Java grammar https://github.com/antlr/grammars-v4/blob/master/java8/Java8.g4 to get a full-blown Java parser and then use it to extract any information you need about Java files.
