    <p>I am writing a Java web app and put in Tomcat to run.</p> <p>When I tried to use a method included in JAR (which I am sure it contains the method I need), it shows:</p> <pre><code>java.lang.NoSuchMethodError: com.couchbase.client.CouchbaseClient.asyncGetBulk(Ljava/util/Collection;)Ljava </code></pre> <p>But I tried to started tomcat by <code>-verbose:class</code>, I see the following log:</p> <pre><code>[Loaded net.spy.memcached.ops.VBucketAware from file:/.../apache-tomcat-5.5.30/webapps/.../WEB-INF/lib/spymemcached-2.8.2.jar] [Loaded net.spy.memcached.protocol.binary.SingleKeyOperationImpl from file:/.../apache-tomcat-5.5.30/webapps/.../WEB-INF/lib/spymemcached-2.8.2.jar] [Loaded net.spy.memcached.protocol.binary.GetOperationImpl from file:/.../apache-tomcat-5.5.30/webapps/.../WEB-INF/lib/spymemcached-2.8.2.jar] Exception in thread "Thread-2139" java.lang.NoSuchMethodError: com.couchbase.client.CouchbaseClient.asyncGetBulk(Ljava/util/Collection;)Ljava/util/concurrent/Future </code></pre> <p>While spymemcached-2.8.2.jar contains the method, so I do not understand why it fails.</p> <p>This is how I call the method:</p> <pre><code>Future&lt;Map&lt;String,Object&gt;&gt; f = client.asyncGetBulk(key); </code></pre> <p>Thanks for your help.</p> <p><strong>Update 1:</strong></p> <p>By using the code @Narendra Pathai provides, I got the following result</p> <pre><code>[ file:/.../WEB-INF/classes/, file:/.../WEB-INF/lib/activation-1.1.jar, file:/.../WEB-INF/lib/commons-codec-1.5.jar, file:/.../WEB-INF/lib/commons-lang-2.2.jar, file:/.../WEB-INF/lib/commons-logging-1.1.1.jar, file:/.../WEB-INF/lib/couchbase-client-1.0.3.jar, file:/.../WEB-INF/lib/jaxb-api-2.1.jar, file:/.../WEB-INF/lib/jaxb-impl-2.1.9.jar, file:/.../WEB-INF/lib/jettison-1.1.jar, file:/.../WEB-INF/lib/netty-3.2.0.Final.jar, file:/.../WEB-INF/lib/runtime-0.4.1.5.jar, file:/.../WEB-INF/lib/spymemcached-2.8.2.jar, file:/.../WEB-INF/lib/stax-api-1.0-2.jar, file:/.../WEB-INF/lib/xxx_core.jar, file:/.../WEB-INF/lib/xxx_couchbase.jar ] </code></pre> <p>They do not contain the file with the path <code>com.couchbase.client.CouchbaseClient.asyncGetBulk</code> except couchbase-client-1.0.3.jar.</p> <p><strong>Update 2:</strong></p> <p>By using the code:</p> <pre><code>CodeSource codeSource = CouchbaseClient.class.getProtectionDomain().getCodeSource(); if (codeSource != null) { log.debug(codeSource.getLocation()); } CodeSource codeSource2 = net.spy.memcached.MemcachedClient.class.getProtectionDomain().getCodeSource(); if (codeSource2 != null) { log.debug(codeSource2.getLocation()); } </code></pre> <p>I have got the following result:</p> <pre><code>file:/.../WEB-INF/lib/couchbase-client-1.0.3.jar file:/.../WEB-INF/lib/spymemcached-2.8.2.jar </code></pre> <p>It seems that they are correct too.</p>

    1. COThere might be another jar in the classpath which contains the method.

    2. COThat seems weird! Can you use Java decompiler to explore the jar in which you expect to find the method and see if the class contains the method. That would help me in finding out the problem

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
