*Note: this is currently a work in progress.*

This guide describes how to build ESME and deploy it to the SAP NetWeaver Composition Environment (aka "CE"), which is SAP's Java EE 5-compliant application server and integration platform.

h3. 1. Build ESME from the latest code drop


h3. 2. Convert the esme.war into a deployable element

On your CE installation, there are [scripts|http://help.sap.com/saphelp_nwce71/helpdata/en/46/1bd4293d034f08e10000000a114a6b/content.htm] to do such actions


D:\usr\sap\CE1\J00\j2ee\deployment\scripts>make_SDA esme.war \-pr esme.propertiesContents of esme.properties file

{noformat}
softwaretype=single-module
subtype=war
context-root=/esme
vendor=esme.apache.org
location=Deployment Manager
counter=1
{noformat}

h3. 3. Deploy


h4. 3.1. via the Netweaver Developer Studio

Deploy the war file created in step 2 via the Deplyoment Perspective in NWDS.


h4. 3.2 via telnet

you can also deploy using telnet ([http://help.sap.com/saphelp_nwpi711/helpdata/en/45/0ad8e787652d6ae10000000a11466f/content.htm|http://help.sap.com/saphelp_nwpi711/helpdata/en/45/0ad8e787652d6ae10000000a11466f/content.htm]):

h4. 3.3 via script

D:\usr\sap\CE1\J00\j2ee\deployment\scripts> deploy administrator:abcd1234@localhost:50004 esme.war

h3. Tips


h5. Using container-based autnetication

You must also change the web.xml file

{noformat}
<resource-ref>
<res-ref-name>esme</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
{noformat}
You also have to of course create a data source and the necessary JDBC drivers to the CE environment. Here are two blogs with details on how to do this:
* [Creating JDBC Data sources using NWA for different Databases in CE|http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/12141]
* [Connecting an Application to an External Database in SAP NW CE 7.1|http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/8675]

If you are using derby as your DB to perform tests, the following info is useful:
* DB driver class: _org.apache.derby.jdbc.EmbeddedDriver_
* URL: _jdbc:derby:esme_db;create=true_
* JAR_: derby-10.5.1.1.jar\_
