Jar does not work but program works inside IDE

Question

I have a java program, which works correctly inside IDE. However when i create jar, it does not work. What's the problem?

        StringBuilder builder = new StringBuilder();
    builder.append("name=" + name);
    builder.append(System.getProperty("line.separator"));
    builder.append("library=\"" + library + "\"");
    builder.append(System.getProperty("line.separator"));
    builder.append("slot=" + slot);

    ByteArrayInputStream bais = new ByteArrayInputStream(builder.toString().getBytes());
    /*exception line  */SunPKCS11 provider = new SunPKCS11(bais);


Exception in thread "main" java.lang.NoSuchMethodError: 'void sun.security.pkcs11.SunPKCS11.<init>(java.io.InputStream)'
at JcaProvider.createProvider(JcaProvider.java:70)
at Test.main(Test.java:31)

There is no error or warning when I create jar, Can someone help me?

NoSuchMethodErrors typically mean Version Mismatches. This can only happen when the compiler and the jvm that executes it, see different method signatures.

In your case, I suspect that java is a different jvm than the one supplied by Netbeans. Open the Netbeans folder and lookout for a java installation. Using that installation will probably owkr.

Note that sun.* packages are proprietary Sun API and thus it's very possible that it's not available in your java installation (e.g. oracle jvm vs openJDK jvm). Or you might be using post-java-8 jvm's, where they changed a few things (removed some classes out, which require enabling or others).

So in other words: If you have the chance, try to find replacements for sun packages.

indeed, the InputStream constructor disappeared since Java 9 by the looks of it. And that seems to be because obtaining a Provider instance is [done differently](https://stackoverflow.com/questions/46521791/sunpkcs11-provider-in-java-9). — Gimby, Dec 06 '19 at 16:02
