classNotFound for sql handler

[Derrick Cui]

Hi,

I installed solr 9.6.1, I want to use the sql function, but the server
throws a classNotFound error., anyone have an idea why this class is not in
solr 9.6.1? Do I need to install a special jar?

{
  "error": {
    "metadata": [
      "error-class",
      "org.apache.solr.common.SolrException",
      "root-error-class",
      "java.lang.ClassNotFoundException"
    ],
    "msg": " Error loading class 'solr.SQLHandler'",
    "trace": "org.apache.solr.common.SolrException:  Error loading class
'solr.SQLHandler'\n\tat
org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:551)\n\tat
org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:472)\n\tat
org.apache.solr.core.SolrCore.createInstance(SolrCore.java:939)\n\tat
org.apache.solr.core.PluginBag$LazyPluginHolder.createInst(PluginBag.java:520)\n\tat
