    +title: Troubleshooting Exceptions and Node Failure
    +toc: /guide/toc.json
    +Whether you're customizing out-of-the-box blueprints, or developing your own custom blueprints,
you will
    +inevitably have to deal with node failure, or exceptions being thrown by your node. Thankfully
    +provides plenty of information to help you locate and resolve any issues you may encounter.
    +This guide looks at three common failure scenarios and describes the steps that can be
taken to
    +identify the issue.
    +## Script failure
    +Many blueprints run bash scripts as part of the installation. This section highlights
how to identify a problem with
    +a bash script.
    +First let's take a look at the `customize()` method of the Tomcat server blueprint:
    +{% highlight java %}
    +  @Override
    +  public void customize() {
    +      newScript(CUSTOMIZING)
    +          .body.append("mkdir -p conf logs webapps temp")
    +          .failOnNonZeroResultCode()
    +          .execute();
    +      copyTemplate(entity.getConfig(TomcatServer.SERVER_XML_RESOURCE), Os.mergePaths(getRunDir(),
"conf", "server.xml"));
    +      copyTemplate(entity.getConfig(TomcatServer.WEB_XML_RESOURCE), Os.mergePaths(getRunDir(),
"conf", "web.xml"));
    +      // Deduplicate same code in JBoss
