<p>I did most of the changes or modifications suggested by different
blogs and forums.</p>
<p>It is suppose to work with Java 8 but my getting lot of errors when
using JDK 8 during startup of the portal server.</p>

GA release. If I remember correctly, not all 6.2 releases were even
compatible with Java8, so at a minimum you should be on the latest
available GA release, <a
href="https://liferay.dev/blogs/-/blogs/security-patches-for-liferay-portal-6-2-7-0-and-7-1">with
the available patch</a>.</p>
<p>But, as you're there anyway: Upgrade more than just your JDK and move
forward to the latest version. If only to be future proof and get more
security fixes should they be required.</p>
<p>Other than that: Protocol support is rather dependent on Tomcat (or
whatever Appserver you're running) rather than Liferay</p>Olaf Kock2021-04-01T10:26:40ZReceived fatal alert : protocol_version error in Liferay 6.2 with Java 7Shahbaz Khanhttps://liferay.dev/en/c/message_boards/find_message?p_l_id=119785333&messageId=1207000942021-03-29T08:31:16Z2021-03-29T08:29:46Z<p>Hello Friends,</p>
<p> </p>
<p>I need to call a service to send a json post request.</p>
<p>When I'm calling it through a custom portlet I'm getting SSL
exception with saying fatal error.</p>
<p>I tried to search and did modifications as said in different forums
like adding <strong>-Dhttps.protocols=TLSv1.1,TLSv1.2</strong> to
setenv.bat and adding System.setproperty method and many more but
nothing works.</p>
<p>I knew need to upgrade the JDK to 1.8 but even that showing lot of
errors and exceptions during startup of the tomcat server.</p>
<p>How can it be
