    The problem you face know is because Oracle added MD5withRSA to the list of disabledAlgorithms. This is documented on Oracle's website as Java is their product:

    The list of disabled algorithms is controlled via the security property, jdk.jar.disabledAlgorithms, in the file. This property contains a list of disabled algorithms and key sizes for cryptographically signed JAR files. You can remove the MD5withRSA from the mentioned file and then you will not get the errors. This requires no update or upgrade.

    Best regards,

    I did find the Java security file and opened with Word Pad and I can See MD5 .

    What changes should i Make to the file could you please help here.

    below are lines I pasted where I found MD5 in the file


    jdk.certpath.disabledAlgorithms=MD2, MD5, SHA1 jdkCA & usage TLSServer, \

    RSA keySize < 1024, DSA keySize < 1024, EC keySize < 224


    jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024


    # Example:

    # jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048 jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 768, \

    EC keySize < 224


    # Example:

    # jdk.tls.legacyAlgorithms=DH_anon, DES_CBC,SSL_RSA_WITH_RC4_128_MD5






    maxTransforms 5,\

    maxReferences 30,\

    disallowReferenceUriSchemes file http https,\

    minKeySize RSA 1024,\

    minKeySize DSA 1024,\




    Can you please help here what changes I should make so that I dont get error ?
