13 The Java SDK provides a generic set of wrappers so you can make API calls in java.
17 * The Java SDK requires Java 6 or later
19 * The Java SDK is implemented as a maven project. Hence, you would need a working
20 maven environment to be able to build the source code. If you do not have maven setup,
21 you may find the "Maven in 5 Minutes":http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html link useful.
23 * In this document $ARVADOS_HOME is used to refer to the directory where
24 arvados code is cloned in your system. For ex: $ARVADOS_HOME = $HOME/arvados
27 h3. Setting up the environment
29 * The SDK requires a running Arvados API server. The following information
30 about the API server needs to be passed to the SDK using environment
31 variables or during the construction of the Arvados instance.
35 ARVADOS_API_TOKEN: API client token to be used to authorize with API server.
37 ARVADOS_API_HOST: Host name of the API server.
39 ARVADOS_API_HOST_INSECURE: Set this to true if you are using self-signed
40 certificates and would like to bypass certificate validations.
44 * Please see "api-tokens":{{site.baseurl}}/user/reference/api-tokens.html for full details.
47 h3. Building the Arvados SDK
51 $ <code class="userinput">cd $ARVADOS_HOME/sdk/java</code>
53 $ <code class="userinput">mvn -Dmaven.test.skip=true clean package</code>
54 This will generate arvados sdk jar file in the target directory
59 h3. Implementing your code to use SDK
61 * The following two sample programs serve as sample implementations using the SDK.
62 <code class="userinput">$ARVADOS_HOME/sdk/java/ArvadosSDKJavaExample.java</code> is a simple program
63 that makes a few calls to API server.
64 <code class="userinput">$ARVADOS_HOME/sdk/java/ArvadosSDKJavaExampleWithPrompt.java</code> can be
65 used to make calls to API server interactively.
67 Please use these implementations to see how you would use the SDK from your java program.
69 Also, refer to <code class="userinput">$ARVADOS_HOME/arvados/sdk/java/src/test/java/org/arvados/sdk/java/ArvadosTest.java</code>
70 for more sample API invocation examples.
72 Below are the steps to compile and run these java program.
74 * These programs create an instance of Arvados SDK class and use it to
75 make various <code class="userinput">call</code> requests.
77 * To compile the examples
80 $ <code class="userinput">javac -cp $ARVADOS_HOME/sdk/java/target/arvados-sdk-1.1-jar-with-dependencies.jar \
81 ArvadosSDKJavaExample*.java</code>
82 This results in the generation of the ArvadosSDKJavaExample*.class files
83 in the same directory as the java files
90 $ <code class="userinput">java -cp .:$ARVADOS_HOME/sdk/java/target/arvados-sdk-1.1-jar-with-dependencies.jar \
91 ArvadosSDKJavaExample</code>
92 $ <code class="userinput">java -cp .:$ARVADOS_HOME/sdk/java/target/arvados-sdk-1.1-jar-with-dependencies.jar \
93 ArvadosSDKJavaExampleWithPrompt</code>
98 h3. Viewing and Managing SDK logging
100 * SDK uses log4j logging
102 * The default location of the log file is
103 <code class="userinput">$ARVADOS_HOME/sdk/java/log/arvados_sdk_java.log</code>
105 * Update <code class="userinput">log4j.properties</code> file to change name and location of the log file.
109 $ <code class="userinput">nano $ARVADOS_HOME/sdk/java/src/main/resources/log4j.properties</code>
110 and modify the <code class="userinput">log4j.appender.fileAppender.File</code> property as needed.
113 $ <code class="userinput">mvn -Dmaven.test.skip=true clean package</code>
118 h3. Using the SDK in eclipse
120 * To develop in eclipse, you can use the provided <code class="userinput">eclipse project</code>
122 * Install "m2eclipse":https://www.eclipse.org/m2e/ plugin in your eclipse
124 * Set <code class="userinput">M2_REPO</code> classpath variable in eclipse to point to your local repository.
125 The local repository is usually located in your home directory at <code class="userinput">$HOME/.m2/repository</code>.
130 Window -> Preferences -> Java -> Build Path -> Classpath Variables
131 Click on the "New..." button and add a new
132 M2_REPO variable and set it to your local Maven repository
137 * Open the SDK project in eclipse
141 File -> Import -> Existing Projects into Workspace -> Next -> Browse
142 and select $ARVADOS_HOME/sdk/java
