I written a java code for load performance and i compile that with google url its execute successfully but i enter my url which has no ssl certificate, The code is doesn't execute and its display this exception,

As per SSL Encryption chapter of JMeter Documentation:

The JMeter HTTP samplers are configured to accept all certificates, whether trusted or not, regardless of validity periods, etc. This is to allow the maximum flexibility in testing servers.

It means that if you use HTTP Request sampler it will be successfully executed even if there are problems with server-side certificates.

If you wrote your own java code and trying to use it in JSR223 Test Element or trying to create a JMeter plugin you can create a special SSLSocketFactory which will trust all certificates like it's described in Trusting all certificates using HttpClient over HTTPS thread

In any case we cannot comprehensively assist without seeing your full code.

Probably there is something wrong with your project dependencies. You can take i.e. [jmeter-from-code](https://bitbucket.org/blazemeter/jmeter-from-code/src/master/) example project as a basis. See [JMeter Command Line Overview: 5 Ways To Launch a Test](https://www.blazemeter.com/blog/jmeter-command-line) article for general information on various ways of launching a JMeter test in non-GUI mode. – Dmitri T Mar 02 '23 at 11:24
