3 - Using the Arvados Java SDK, you can access API server from a java program.
5 - Please refer to http://doc.arvados.org/api/index.html for a complete list
6 of supported resources and methods.
8 - This document highlights the details as to how to use the SDK.
10 - The Java SDK is used as a maven project. Hence, you would need a working
11 maven environment to be able to build the source code.
13 If you do not have maven setup, you may find the following link useful.
15 http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html
17 - In this document <ARVADOS_HOME> is used to refer to the directory where
18 arvados code is cloned in your system.
19 For ex: <ARVADOS_HOME> = $HOME/arvados
22 == Setting up the environment
24 - The SDK requires a running Arvados API server. The information about the
25 API server needs to be passed to the SDK using environment variables or
26 during the construction of the Arvados instance.
28 - If you would like to use environment variables, below are the details.
32 API client token to be used to authorize with API server.
34 export ARVADOS_API_TOKEN=z40gplmla6i58rsg96jhg5u41ewdl5rj4g1py2s6e2lsc3
38 Host name of the API server.
40 export ARVADOS_API_HOST=localhost:3001
42 3. ARVADOS_API_HOST_INSECURE
44 Set this to true if you are using self-signed certificates and
45 would like to bypass certificate validations.
47 export ARVADOS_API_HOST_INSECURE=true
50 == Building the Arvados SDK
52 - cd <ARVADOS_HOME/sdk/java
56 This will generate arvados sdk jar file in the target directory
59 == Implementing your code to use SDK
61 - <ARVADOS_HOME>/sdk/java/ArvadosSDKJavaExample.java serves as an example
62 implementation using the java SDK. Please use this file to see how
63 you would want use the SDK from your java program.
64 The steps below use this java class name.
66 - ArvadosSDKJavaExample.java creates an instance of Arvados SDK class and
67 uses it to make various "call" requests.
69 - To compile ArvadosSDKJavaExample.java
71 javac -cp <ARVADOS_HOME>/sdk/java/target/arvados-sdk-1.0-jar-with-dependencies.jar ArvadosSDKJavaExample.java
73 This results in the generation of the ArvadosSDKJavaExample.class file
74 in the same directory as the java file
76 - To run the class file
78 java -cp .:<ARVADOS_HOME>/sdk/java/target/arvados-sdk-1.0-jar-with-dependencies.jar ArvadosSDKJavaExample
81 == Viewing and managing SDK logging
83 - SDK uses log4j logging
85 - The default location of the log file is
86 <ARVADOS_HOME>/sdk/java/log/arvados_sdk_java.log
88 - Update log4j.properties file to change name and location of the log file.
90 Modify the "log4j.appender.fileAppender.File" property in log4j.properties
91 file located at <ARVADOS_HOME>/sdk/java/src/main/resources
93 Rebuild by running "mvn clean package"
96 == Using the SDK in eclipse
98 - To develop in eclipse, you can use the SDK eclipse project.
100 - Install "m2eclipse" plugin in your eclipse
102 - Set M2_REPO to your .m2/repository directory
104 - Open the SDK project.
106 File -> Import -> Existing Projects into Workspace -> Next -> Browse
107 and select <ARVADOS_HOME>/sdk/java
