When you use JRE in SAS 9.2, you might encounter errors similar to the following:

ERROR: Unable to attach current thread" ERROR: Unable to load the java virtual machine"
ERROR: The Java proxy is not responding. ERROR: The Java proxy's JNI call to start the VM failed.
ERROR: Proc javainfo did not run correctly

To resolve these issues with JRE, use the following steps.  Note: Click the Full Code tab, above, for an automated version of these steps using SAS code.

1. Double-check your JREOPTIONS settings by submitting the following code:

   proc options option=jreoptions; 
   run;

   At the beginning of the JREOPTIONS output in the SAS log, a value similar to the following appears:

    -Dsas.jre.libjvm=C:\PROGRA~1\Java\JRE15~2.0_1\bin\client\jvm.dll

2. Navigate to this location and check that the jvm.dll file is saved there.
3. At a command prompt, navigate to the bin directory found in Step 1 and enter java –version to display the JRE version that is installed on your computer. For most versions of Windows, ensure that you have JRE version 5.  Windows 7 or Windows 2008 Server require JRE version 6 (32-bit). See SAS 9.2 (TS2M3) Support for Java Runtime Environments for details.
4. Open your SAS configuration file, which is located in c:\program files\sas\sasfoundation\9.2\nls\en\sasv9.cfg.
5. In the sasv9.cfg file, locate the -jreoptions line. Ensure that all of the text is on one line of this file and that spaces are inserted at the start of each option. Each option begins with a hyphen (-).
6. Look for error messages in the Java log located in C:\Documents and Settings\your-user-ID\Application Data\SAS\LOGS.

If necessary, reinstall JRE from Third-Party Software Requirements for Use with SAS^® Software and Applications. 

If the above steps do not resolve your issue, send an email message to SAS Technical Support. In your email, include your sasv9.cfg file, the output from Step 1, and any Java logs from Step 6.
