iSeries Toolbox for Java

Page history last edited by PBworks 16 years, 6 months ago

There are two options: IBM iSeries Toolbox for Java licensed program (free of charge), and JTOpen.


JTOpen is the open source version of the toolbox.


Both are sets of code for accessing native iSeries resources from Java software, requiring nothing more than the standard JVM (they communicate with the standard OS/400 host servers).


JTOpen leads the iSeries Toolbox LPP by about 6 months, but the same development team maintains both sets of code and fixes to JTOpen are often provided much faster than the PTFs/release cycles associated with the Toolbox. Web support for JTOpen via email and mailing lists is available, plus IBM will support the JTOpen toolbox in the same way as their other products.


More details at:

http://jt400.sourceforge.net/ (JTOpen)

http://www-03.ibm.com/servers/eserver/iseries/toolbox/ (Toolbox)


Be aware that a ready-optimised version of the Toolbox is shipped at /QIBM/ProdData/Java400/jt400ntv.jar, while JTOpen will require optimisation to level 40 via CRTJVAPGM whenever a new version is loaded onto the iSeries.


Little-known but useful functionality within the Toolbox allows the creation of 'external description' Java classes from iSeries physical files - see JAVACLASS CL program and CreateJavaExternalDescription Java source, as used within our Address Validation real-life example.


More Toolbox information and examples can be found here.


Here is another example, a data queues one this time.
