PQ69795: MANUALS CONTAIN NO DOCUMENTATION FOR USING JAVA AWT CLASSES | |||||||||||||||||||||||||
![]() |
|||||||||||||||||||||||||
APAR status Closed as documentation error. Error description Program Directory states that java AWT classes are supported but there is no documentation on the steps to setup a proper environment for them to function. There is one statement but it appears to be wrong or incomplete. Testing an AWT app in the plugin, it appears that: 1) environment variable DISPLAY must be set in httpd.envvars DISPLAY=x.xx.xx.xx:0.0 2) variables LANG and LC_ALL must be set to "C" in httpd.envvars LANG=C and LC_ALL=C 3) LIBPATH in httpd.envvars needed to have /usr/lib added to the concatenation so we picked up Xm.dll and X11.dll ---------------------------------------------------------------- We have been unable to run a java AWT app in the webcontainer at this time, so we have not been able to test that environment. ---------------------------------------------------------------- The program directory states that you need to perform an export DISPLAY=x.xx.xx.xx command, but it appears that is to run an AWT app from omvs outside of WebSphereLocal fix HBCProblem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0.1 for z/OS and OS/390. * * * **************************************************************** * PROBLEM DESCRIPTION: The "WebSphere Application Server * * V4.0.1 for z/OS and OS/390 Program * * Directory" states that Java AWT classes * * are supported, but there is no * * documentation on the steps required * * to setup an environment in which they * * can run . * * * **************************************************************** * RECOMMENDATION: * **************************************************************** The "WebSphere Application Server V4.0.1 for z/OS and OS/390 Program Directory" states that Java AWT classes are supported, but there is no documentation on the steps required to setup an environment in which they can run. A description of the required setup needs to be added to "WebSphere Application Server V4.0.1 for z/OS and OS/390: Assembling J2EE Applications," SA22-7836.Problem conclusion The following note will be added to the first step in Chapter 2. Overview of application development and tools of "WebSphere Application Server V4.0.1 for z/OS and OS/390:Assembling J2EE Applications," SA22-7836: c. Java AWT classes are supported but an application containing a Java AWT class must be hosted in the Local Redirector Plug-in. If you want to use Java AWT classes, you must make the following changes to the HTTP Server's httpd.envvars file: 1. Set the DISPLAY environment variable to "x.xx.xx.xx:0.0 where x.xx.xx.xx:0.0 is the XWindows environment variab stating the IP address of the XTerminal. 2. Set the LANG and LC_ALL environment variables to "C". 3. Add "/usr/lib" to the LIBPATH so that you pick up Xm.dl and X11.dll More information about using AWT classes is available at URL: http://java.sun.com/products/jdk/awt/ NOTE: Periodically, we refresh the documentation on our Web site, so the changes might have been made before you read this text. To access the latest on-line documentation, go to the product library page at: http://www.ibm.com/software/webservers/appserv/zos_os390/library .html APAR PQ69797 has been opened to add Java AWT classes support for applications hosted in the Web container.Temporary fix Comments
