Take a look at the returned data using curl. It is JSON, not XML, therefore you cannot parse it this way. Use a JSON parser instead, or figure out the API parameter needed to make the service return XML.

I noticed BouncyCastle v1.60 does not throw an error during validation after modifying (pseudo) random bits of the response. In the two responses below, you'll notice all the a's have been swapped with b's. BouncyCastle returns the Unix epoch as the generated time.
Code:
TimeStampToken.validate(SignerInformationVerifier)
Algorithm: SHA-256
Data: "test string" (no quotes)

Unfortunately you initially didn't share the relevant code. Thus, I had to build some code myself, test with that code, and answer your question based on that code.
The result: For your manipulated response already parsing fails, so there is no way to try and validate it.

The result
During the attempt to validate the manipulated timestamp response already in the line
responseResp = TimeStampResp.getInstance(responseBytes);
an exception is thrown:
java.lang.IllegalArgumentException: failed to construct sequence from byte[]: DEF length 27 object truncated by 1
at org.bouncycastle.asn1.ASN1Sequence.getInstance(Unknown Source)
at org.bouncycastle.asn1.tsp.TimeStampResp.getInstance(Unknown Source)
at mkl.testarea.bc1.timestamp.ValidateTST.testValidateLikeUser8897013(ValidateTST.java:75)
Thus, the response cannot be parsed. As a consequence, TimeStampToken.validate cannot be called for it.
Using your code
After you eventually published your code, I also tested that code:
responseBytes = Hex.decode(responseChangedHex);
TimeStampResponse response = new TimeStampResponse(responseBytes);
TimeStampToken token = response.getTimeStampToken();
TimeStampTokenInfo tokenInfo = token.getTimeStampInfo();
But also here I get an exception already while parsing the manipulated response:

i.e. in this line
TimeStampResponse response = new TimeStampResponse(responseBytes);
As a consequence, TimeStampToken.validate cannot be called for your response even if one uses TimeStampResponse instead of TimeStampResp.
BC versions
As you expressed doubts in a comment: I do use BC 1.60 for the test having both bcprov-jdk15on-1.60.jar and bcpkix-jdk15on-1.60.jar in my classpath and having registered BC as security provider:
Security.addProvider(new BouncyCastleProvider());
To me this is a completely normal BC setup.
I am getting following error while using the SharePoint web service:

I am trying to access SharePoint 2010 web service using the following code:
public void querySharePointFolder(ListsSoap ls) throws Exception {
try
{
disableCertificateValidation();
GetListItems.ViewFields viewFields = null;
GetListItems.QueryOptions msQueryOptions = new GetListItems.QueryOptions();
GetListItems.Query msQuery = new GetListItems.Query();
msQuery.getContent().add(createSharePointCAMLNode(query));
msQueryOptions.getContent().add(createSharePointCAMLNode(this.queryOptions));
GetListItemsResponse.GetListItemsResult result = ls.getListItems(
properties.getProperty("folder"), "", msQuery, viewFields, "",
msQueryOptions, "");
writeResult(result.getContent().get(0), System.out);
Element element = (Element)result.getContent().get(0);
NodeList nl = element.getElementsByTagName("z:row");
for(int i = 0; i < nl.getLength(); i++){
Node node = nl.item(i);
logger.debug("ID: " + node.getAttributes().getNamedItem("ows_ID").getNodeValue());
logger.debug("FileRef: " + node.getAttributes().getNamedItem("ows_FileRef").getNodeValue());
}
}
catch(Exception e)
{
e.printStackTrace();
}
}
But its showing the error at following line:
GetListItemsResponse.GetListItemsResult result = ls.getListItems(
properties.getProperty("folder"), "", msQuery, viewFields, "",
msQueryOptions, "");
Can you please help me out over this as after using different different approaches i am still getting the same issue 403: Forbidden.
I am using the same credential here through which i had created the folder over SharePoint. Do I need any other privileges for that credential to get the access.
So this is my first time posting, please be gentle :3
General overview:
My goal is to be able to give my program a XSD file, then the program generates a bean, generates a nice GUI using reflection on the bean, then I can enter appropriate values into the textfields and then the program updates the bean with the values and finally marshalls the bean into a nice XML.
It's coming along pretty good, but yesterday I stumbled over an error that I can't figure out..

return beanClass;

So I checked first if the beanBinaryName is correct, and I think it is. It has the following format:
com.foo.foo.some.more.foo.beanbag.bean
Then I started googling with the error message and stumbled accross this post:

But to be honest I didn't really understand what he was trying to explain. The stacktrace looks similar, but I just started with java a few months ago and still consider myself a newbie. Do you have any advice what the error might be? Thank in advance!
EDIT / SOLUTION:
My first mistake was trying to use class.forName() on a .java file. This only works with compiled files, e.g. .class.
After I fixed that i was still getting error messages, but after playing around with the URLClassLoader it worked :D I renamed and refactored this method compared to the method at the top, so in this one we really only get the class, while in my first example I also generate the .java files. I now do this in a seperate method to keep things organized.
public Class getClassFromBean() {
File[] fList = new File[3];
fList = new File("foo/beanbag").listFiles();
Class beanClass = null;
for (File file : fList) {
String lastSix = file.getName().toString().substring(file.getName().length() - 6);
if (".class".equals(lastSix)) {
String beanBinaryName = "foo.beanbag."
+ file.getName().toString().substring(0, file.getName().toString().length() - 6);
try {
File root = new File(System.getProperty("user.dir") + "/src/main/java");
URLClassLoader classLoader = URLClassLoader.newInstance(new URL[] { root.toURI()
.toURL() });
beanClass = Class.forName(beanBinaryName, true, classLoader);
} catch (ClassNotFoundException | MalformedURLException e) {
Gui.errorPopUp(e);
}
return beanClass;
}
}
return beanClass;
}
Method Class.forName() works only for compiled classes i.e. for files with extension '.class'. You cannot just put '.java' file to your classpath.
This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 8 years ago.
I'm generating a KML file and at the point where I use the transformer API, I get the NullPointerException exception. Here's the code I'm refering too:
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(kml);
StreamResult result = new StreamResult(new File("src/mapa/mapa.kml"));
System.out.print("DESPRES DE CREAR RESULT\n");
if(source == null)
System.out.print("SOURCE IS NULL");
if(result == null)
System.out.print("RESULT IS NULL");
transformer.transform(source, result);
System.out.print("AFTER TRASNFORM\n");
It doesn't print any of the NULL System.outs, however it doesn't print the last one either. Why is it giving me NPE?
Exception:

Try the below code
System.out.print(transformerFactory.newTransformer());
It probably returns null, making your transformer object null.
For a little university project i'm doing, i need to extract code samples from html given as a string.
To by more precise, i need to get from that html string, everything in between <code> and </code>.
I'm writing in Java, and using String.match to do that.
My code:
public static ArrayList<String> extractByHTMLtagDelimiters(String source, String startDelimiter, String endDelimiter){
ArrayList<String> results = new ArrayList<String>();
if (source.matches("([\t\n\r]|.)*" + startDelimiter + "([\t\n\r]|.)*" + endDelimiter)){
//source has some code samples in it
//get array entries of the form: {Some code}</startDelimiter>{something else}
String[] splittedSource = source.split(startDelimiter);
for (String sourceMatch : splittedSource){
if (sourceMatch.matches("([\t\n\r]|.)*" + endDelimiter + "([\t\n\r]|.)*")){
//current string has code sample in it (with some body leftovers)
//the code sample located before the endDelimiter - extract it
String codeSample = (sourceMatch.split(endDelimiter))[0];
//add the code samples to results
results.add(codeSample);
}
}
}
return results;
iv'e tried to extract that samples from some html of ~1300 chars and got pretty massive exception: (it goes on and on for few dozens of lines)

i've found the following bug report:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5050507
is there anything i can do to still use string.match? if not, can you please recommend some other way to do it without implementing html parsing by myself?
Thank a lot,
Dub.
You can just manually go through the input string using String's indexOf() method to find the start and end deliminters and extract out the bits between yourself.
public static void main(String[] args) {
String source = "<html>blah<code>this is awesome</code>more junk</html>";
String startDelim = "<code>";
String endDelim = "</code>";
int start = source.indexOf(startDelim);
int end = source.indexOf(endDelim);
String code = source.substring(start + startDelim.length(), end);
System.out.println(code);
}
If you need to find more than one, then just use indexOf again starting at the point you finished:
int nextStart = source.indexOf(startDelim, end + endDelim.length())
Simply replace your regex pattern with "(?s).*"
This matches anything including new lines as you intended.
