Hi, I use the java client to connect to a cluster. Which client jars are really needed on the classpath ?? I connect via the transport client. And in particular I use it in JBoss EAP 6. This seems really not up to date : [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/\_deploying\_in\_jboss\_eap6\_module.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/_deploying_in_jboss_eap6_module.html) I got a lot of ClassNotFoundExceptions on the third party dependencies of elasticsearch itself, like jodaTime, t-digest, jsr166e etc... Why did elastic moved away from shaded packages ? A lot of other clients are for example using other versions of those libraries and it clashes. So for elastic I probably have to create even a separate module for the dependencies of elastic which are not really used by my jboss app so those are not "exported" (in the sense of a jboss module). So again, which client jars are really needed on the classpath ?? Many thanks. Regards, ---

I just answered a similar question for 2.0.0 here [Error while using the Java API](https://discuss.elastic.co/t/error-while-using-the-java-api/35673/4) If you run `mvn dependency:tree` in core project, you get: ```auto [INFO] org.elasticsearch:elasticsearch:jar:2.1.0 [INFO] +- org.apache.lucene:lucene-core:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-backward-codecs:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-analyzers-common:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-queries:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-memory:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-highlighter:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-queryparser:jar:5.3.1:compile [INFO] | \- org.apache.lucene:lucene-sandbox:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-suggest:jar:5.3.1:compile [INFO] | \- org.apache.lucene:lucene-misc:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-join:jar:5.3.1:compile [INFO] | \- org.apache.lucene:lucene-grouping:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-spatial:jar:5.3.1:compile [INFO] | \- org.apache.lucene:lucene-spatial3d:jar:5.3.1:compile [INFO] +- org.apache.lucene:lucene-expressions:jar:5.3.1:compile [INFO] | +- org.antlr:antlr-runtime:jar:3.5:compile [INFO] | +- org.ow2.asm:asm:jar:4.1:compile [INFO] | \- org.ow2.asm:asm-commons:jar:4.1:compile [INFO] +- com.spatial4j:spatial4j:jar:0.5:compile [INFO] +- com.vividsolutions:jts:jar:1.13:compile [INFO] +- com.github.spullara.mustache.java:compiler:jar:0.8.13:compile [INFO] +- com.google.guava:guava:jar:18.0:compile [INFO] +- com.carrotsearch:hppc:jar:0.7.1:compile [INFO] +- joda-time:joda-time:jar:2.8.2:compile [INFO] +- org.joda:joda-convert:jar:1.2:compile [INFO] +- com.fasterxml.jackson.core:jackson-core:jar:2.6.2:compile [INFO] +- com.fasterxml.jackson.dataformat:jackson-dataformat-smile:jar:2.6.2:compile [INFO] +- com.fasterxml.jackson.dataformat:jackson-dataformat-yaml:jar:2.6.2:compile [INFO] | \- org.yaml:snakeyaml:jar:1.15:compile [INFO] +- com.fasterxml.jackson.dataformat:jackson-dataformat-cbor:jar:2.6.2:compile [INFO] +- io.netty:netty:jar:3.10.5.Final:compile [INFO] +- com.ning:compress-lzf:jar:1.0.2:compile [INFO] +- com.tdunning:t-digest:jar:3.0:compile [INFO] +- org.hdrhistogram:HdrHistogram:jar:2.1.6:compile [INFO] +- commons-cli:commons-cli:jar:1.3.1:compile [INFO] +- org.codehaus.groovy:groovy-all:jar:indy:2.4.4:compile [INFO] +- log4j:log4j:jar:1.2.17:compile [INFO] +- log4j:apache-log4j-extras:jar:1.2.17:compile [INFO] +- org.slf4j:slf4j-api:jar:1.6.2:compile [INFO] +- net.java.dev.jna:jna:jar:4.1.0:compile [INFO] \- com.twitter:jsr166e:jar:1.1.0:compile ``` HTH ---
