| |
| <div id="preamble"> |
| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>In addition to <a href="/docs/latest/peer-class-loading">peer class loading</a>, you can deploy user code by configuring <code>UriDeploymentSpi</code>. With this approach, you specify the location of your libraries in the node configuration. |
| Ignite scans the location periodically and redeploys the classes if they change. |
| The location may be a file system directory or an HTTP(S) location. |
| When Ignite detects that the libraries are removed from the location, the classes are undeployed from the cluster.</p> |
| </div> |
| <div class="paragraph"> |
| <p>You can specify multiple locations (of different types) by providing both directory paths and http(s) URLs.</p> |
| </div> |
| </div> |
| </div> |
| <div class="sect1"> |
| <h2 id="deploying-from-a-local-directory">Deploying from a Local Directory</h2> |
| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>To deploy libraries from a file system directory, add the directory path to the list of URIs in the <code>UriDeploymentSpi</code> configuration. |
| The directory must exist on the nodes where it is specified and contain jar files with the classes you want to deploy. |
| Note that the path must be specified using the "file://" scheme. |
| You can specify different directories on different nodes.</p> |
