Installation: NetWeaver Developer Studio 7.3 for NetWeaver 7.4 Portal

Part 1.  Installation of NWDS 7.3 and Java SDK

1. Download NWDS
   1. At this time the latest NWDS is version 7.3 SP16 PAT0005
   2. Use this link to obtain the latest version:
   3. https://nwds.sap.com/swdc/downloads/updates/netweaver/nwds/nw/731/doc/auto_com.sap.netweaver.developerstudio.distribution.complete.extsoa_versions.html
   4. Note: it’s ok to use NWDS 7.3 against your 7.4 Portal
2. Download Java SDK
   1. You can download SAP’s Java Version for use with NWDS or you can use the JDK from SUN. But only one of the following versions should be used.
      1. From SAP: “SAP JVM 6”
         1. https://nwds.sap.com/swdc/downloads/updates/netweaver/nwds/nw/731/doc/files/sapjvm6.msi
         2. From SUN: “Java SE Development Kit 6u45”
            1. http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html#jdk-6u45-oth-JPR
3. Now you have the needed downloads, do the following:
   1. Install your chosen Java version (Note: I used the SUN version)
   2. Reboot
   3. Extract the NWDS zip file to a folder
      1. Execute SapNetweaverDeveloperStudio.exe
      2. During this first run of the NWDS, it will ask you to point to the Java version you previously installed.
      3. Note: if you get an error related to memory (HeapDumpOnOutOfMemoryError) when executing the developers studio exe, modify SapNetweaverDeveloperStudio.ini and change Xmx value to something smaller (example:  Xmx256m).
