After upgrade to spring boot 3, its recommended to use JAKARTA instead of javax

I must find a new way to generate java objects from XSD’ es

I have been recommended this plugin: 'org.unbroken-dome.xjc'

Gradle:

plugins {    id 'org.unbroken-dome.xjc' version '2.0.0' } xjc () {    srcDirName = "$projectDir/src/main/resources/xsd" } //problem was with transitive dependencies for xjcTool    xjcTool 'com.sun.xml.bind:jaxb-xjc:2.3.3'    xjcTool 'com.sun.xml.bind:jaxb-impl:2.3.3'

I have created a binding file like this:

Binding.xml:
<?xml version="1.0" encoding="UTF-8"?> <jaxb:bindings version="2.0" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb">    <jaxb:bindings>        <jaxb:globalBindings typesafeEnumMaxMembers="1000"/>    </jaxb:bindings> </jaxb:bindings>

To setup the typesafeEnumMaxMembers, emums, there is enums that has more values then 256.


I’m getting this error when executing my gradle file:
not mapped to Enum due to EnumMemberSizeCap limit. Facets count: 325, current limit: 256. You can use customization attribute "typesafeEnumMaxMembers" to extend the limit.

I've tried different things, but how do I get gradle to use this binding file?

Maybe there is a faster way, but thought it would take much longer. So I'm going with this solution.

Tested it 100000 times in a loop with this string:

String testString = "Frank is# a star *";

42 milliseconds.

protected static StringBuilder  replaceIllegalCharacterWithSpace(String  input) {        StringBuilder newString = new StringBuilder();        String allowedStrings = "abcdefghijklmnopqrstuvwxyzåäöæøABCDEFGHIJKLMNOPQRSTUVWXYZÅÄÖÆØ0123456789/-?:().,'+ @";        allowedStrings = allowedStrings + " ";        for (int i = 0; i < input.length(); i++) {            char c = input.charAt(i);            if (allowedStrings.indexOf(c) >= 0) {                newString.append(c);            } else {                newString.append(" ");            }        }        return newString;    }

Thanks for all your input out there.

Kind regards
Frank  

I use a string buffer, because it is faster to append than to create a new string each time.

Faster = The fastes way this can be done.

Now comparing >= 0, and removed all the spaces in allowedstring.

Its all single charaters.

Stay tuned on this channel, i will try to make some test ,  on this code postet , if this works, and some performence test , with 100000, strings.

public StringBuffer  replaceIllegalCharacterWithSpace(String  input) {        StringBuffer newString = new StringBuffer();        String allowedStrings = "abcdefghijklmnopqrstuvwxyzåäöæøABCDEFGHIJKLMNOPQRSTUVWXYZÅÄÖÆØ0123456789/-?:().,'+ @";        allowedStrings = allowedStrings + " ";        for (int i = 0; i < input.length(); i++) {            char c = input.charAt(i);            if (allowedStrings.indexOf(c) >= 0) {                newString.append(c);            } else {                newString.append(" ");            }        }        return newString; }

And thanks out there  

Its java strings, and the there is 8 strings length from 40 to 140 character , with name and address.

And yes its correct its data transform with rules.

I just tried with these few lines, it will probably solve it, but think there is a better and faster method ?

Better = nicer code

Fast   = I have to call this methoed 200.000 times every day, will this perform less then 100 Milliseconds ,I can do the performance measurement myself, but maybe there are some out there who know regex or other ways to do this more optimally.


public StringBuffer  replaceIllegalCharacterWithSpace(String  input) {        StringBuffer newString = new StringBuffer();        String allowedStrings = "a b c d e f g h i j k l m n o p q r s t u v w x y z å ä ö æ øA B C D E F G H I J K L M N O P Q R S T U V W X Y Z Å Ä Ö Æ Ø0 1 2 3 4 5 6 7 8 9/ -? : ( ) . , ' + @";        for (int i = 0; i < input.length(); i++) {            char c = input.charAt(i);            if (allowedStrings.indexOf(c) > 0) {                newString.append(c);            } else {                newString.append(" ");            }        }       return newString;    }

I have this character set ,  of Latin and Scandinavian characters:


a b c d e f g h i j k l m n o p q r s t u v w x y z å ä ö æ øA B C D E F G H I J K L M N O P Q R S T U V W X Y Z Å Ä Ö Æ Ø0 1 2 3 4 5 6 7 8 9/ -? : ( ) . , ' + @Space


If have some strings, that I have to validate, if they have characters that DO NOT  match, and if they DO NOT  match,  i must replace the character with a space.
Is this possible via regex, or is there a better way, here I think about speed , and nice  readable code ?

Kind reagrds

I gave up on xpath, I solved my problem by not using xpath, i solved my problem with this code:

NodeList signatureNodeList = doc.getElementsByTagName("Signature");  Element signatureElement = (Element) signatureNodeList.item(0);

Kind regards
Frank

Yeh i can that the Envelope was there.

Im trying with this code now:

XPath xPath = XPathFactory.newInstance().newXPath(); String expression = "/Envelope//Sgntr/Signature[1]"; Element sigElement =  (Element) xPath.evaluate(expression, doc, XPathConstants.NODE);

Maybe my xpath should have some namespace ? , still null

Kind regards Frank

Okay I tryed it,  this way

Element root = doc.getDocumentElement();
NodeList test = root.getElementsByTagNameNS("http://www.w3.org/2000/09/xmldsig#", "Signature");

Now with one header called "Frank"

<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?> <Frank> <Envelope xmlns="http://example.org/envelope"> <Body> body indhold </Body> <Sgntr xmlns="urn:iso:std:iso:20022:tech:xsd:file.001.001.01"> <Signature xmlns="http://www.w3.org/2000/09/xmldsig#"> <SignedInfo> <CanonicalizationMethod Algorithm="http://www.w3.org/2006/12/xml-c14n11"/> <SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha256"/> <Reference URI=""> <Transforms> <Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"/> <Transform Algorithm="http://www.w3.org/2006/12/xml-c14n11"/> </Transforms> <DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256"/> <DigestValue>Bbnejyd4nyitKYm2ZwDWFyAaL1KU4HIm5LHT9QPoe+Q=</DigestValue> </Reference> </SignedInfo> <SignatureValue>w8RdO/4ROCFYm9PNV52V6TvoEDhhN6YyEyiVnOSNCjaHpgEM8jmlPKI+oL0R6PBhD/tCbFheVQFPtirAM9T5KIcXKQBbvvN+jTrPb/H4qlYV7zqZGeFLfGYgsS20RlKyg7HgKQpdNYaHYlOnZg9Kk+65Ghx55d8gplbfxvB+1Fw=</SignatureValue> <KeyInfo><x509Data><x509SubjectName>C=DK,O=Bankdata,OU=SIK,L=Erritsoe Fredericia,CN=Bankdata Produktion CA root 2046</x509SubjectName><x509IssuerSerial>0</x509IssuerSerial><x509IssiuerName>C=DK,O=Bankdata,OU=SIK,L=Erritsoe Fredericia,CN=Bankdata Produktion CA root 2046</x509IssiuerName></x509Data></KeyInfo></Signature></Sgntr> </Envelope> </Frank>

But still he nodelist is empty ?

If have this  as org.w3c.dom object:

Im trying to get the "Sinature" in  a Element, using Xpath.

I cant figure out, why this is not working.

Path xPath = XPathFactory.newInstance().newXPath();   String expression = "/Sgntr/Signature"; NodeList nodeList = (NodeList) xPath.compile(expression).evaluate(doc, XPathConstants.NODESET); Element signatureNode = (Element) nodeList.item(0);

The nodelist have no tiems ?

Yes the problem was that the String strPk was not correct, I will replace it with a PEM file when I get it delivered and use bounty castle, or possibly use https://santuario.apache.org/ if there is something that can do this for me in this package. Thanks for the input, it helped me a lot :-)

String strPk =  "-----BEGIN PRIVATE KEY-----\n"                + "MIICdQIBADANBgkqhkiG9w0BAQEFAASCAl8wggJbAgEAAoGBAM7t8Ub1DP+B91NJ\n"                + "nC45zqIvd1QXkQ5Ac1EJl8mUglWFzUyFbhjSuF4mEjrcecwERfRummASbLoyeMXl\n"                + "eiPg7jvSaz2szpuV+afoUo9c1T+ORNUzq31NvM7IW6+4KhtttwbMq4wbbPpBfVXA\n"                + "IAhvnLnCp/VyY/npkkjAid4c7RoVAgMBAAECgYBcCuy6kj+g20+G5YQp756g95oN\n"                + "dpoYC8T/c9PnXz6GCgkik2tAcWJ+xlJviihG/lObgSL7vtZMEC02YXdtxBxTBNmd\n"                + "upkruOkL0ElIu4S8CUwD6It8oNnHFGcIhwXUbdpSCr1cx62A0jDcMVgneQ8vv6vB\n"                + "/YKlj2dD2SBq3aaCYQJBAOvc5NDyfrdMYYTY+jJBaj82JLtQ/6K1vFIwdxM0siRF\n"                + "UYqSRA7G8A4ga+GobTewgeN6URFwWKvWY8EGb3HTwFkCQQDgmKtjjJlX3BotgnGD\n"                + "gdxVgvfYG39BL2GnotSwUbjjce/yZBtrbcClfqrrOWWw7lPcX1d0v8o3hJfLF5dT\n"                + "6NAdAkA8qAQYUCSSUwxJM9u0DOqb8vqjSYNUftQ9dsVIpSai+UitEEx8WGDn4SKd\n"                + "V8kupy/gJlau22uSVYI148fJSCGRAkBz+GEHFiJX657YwPI8JWHQBcBUJl6fGggi\n"                + "t0F7ibceOkbbsjU2U4WV7sHyk8Cei3Fh6RkPf7i60gxPIe9RtHVBAkAnPQD+BmND\n"                + "By8q5f0Kwtxgo2+YkxGDP5bxDV6P1vd2C7U5/XxaN53Kc0G8zu9UlcwhZcQ5BljH\n"                + "N24cUWZOo+60\n"                + "-----END PRIVATE KEY-----";

I'm trying to make a small test to generate a private key, to make a digital signature. But it already fails on this line " PrivateKey privateKey = kf.generatePrivate(spec);"
Exception is:

java.security.InvalidKeyException: IOException : null

Been trying to find a solution for the last several hours with my friend Google, but can't figure out why this is going wrong.

I have a test of resilience4j.circuitbreaker.CircuitBreaker
Runs fine but the state done changed from closed after 10 times, its run 15 times and allways closed.
Can anyone see what its wrong, I think its something about the supplier.

import io.github.resilience4j.circuitbreaker.CircuitBreaker; @Test    public void testCircutBreakerError() throws IOException, QuickPayV10ServiceClient.QuickPayException {        //getCircutBreaker(String name,int slidingWindowSize,int failureRateThreshold) {        CircuitBreaker paymentCircuitBreaker = PaymentCircuitBreaker.getCircutBreaker(getClass().getName(), 10, 70);        Supplier<String> supplier = () -> {            try {                return this.throwException(null);            } catch (IOException e) {                e.printStackTrace();            }            return null;        } ;        for (int i = 0; i < 15; i++) {            try {                PaymentCircuitBreaker.getCircutBreaker(getClass().getName(), 10, 70);                paymentCircuitBreaker.executeSupplier(supplier);            } catch (Exception ignore) {}        }    }    private String  throwException(String test) throws IOException {        if(test != null) {            return "ok";        }else {            throw new IOException();        }    }

How long does it take to execute exportAllDeleteData() and exportAddAllData()?  Could it be that the client side is only willing to wait up to 30 seconds for a response and bailed before your processing has had a chance to complete?

The program runs for 45 seconds,  you are absolutely right, that was the problem, I owe you a beer, thank you very much for giving yourself time to answer, you are my hero :-)

Himai Minh wrote:Hi, Frank,
one thing you can try is to put this property in your application.properties under the resources folder of your project:
logging.level.org.springframework = info
Then,you can see what information is printed out on the console when you run the code.
It is better to see if there is any exception thrown from the output console.

I allready have log info on the test server. :-)

Yehh maybe is returning HTML , becouse the client timeouts, while the server still is running the code, i will create some loginfo in the morning, to see if it takes over 30 seconds.
