PROC HTTP

I am receiving a strange module error when attempting to execute a simple PROC HTTP.

I am using RHE Linux 64bit and SAS 9.2

I execute sas using the following system options:

./sas -jreoptions "\(-Djavax.net.ssl.trustStore=full-path-to-the-trust-store -Djavax.net.ssl.trustStorePassword=trustStorePassword -Dsas.app.class.path=/usr/local/SAS/SASVersionedJarRepository/9.2/eclipse/plugins\)" &

Code:

filename in "/tmp/FriedEgg_ProcHTTP_in";
filename out "/tmp/FriedEgg_ProcHTTP_out.png";
data _null_;
file in;
input;
put _infile_;
datalines;
cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World
;

proc http in=in out=out url="https://chart.googleapis.com/chart"
method="post"
ct="application/x-www-form-urlencoded";
run;

I am assuming I am missing some jreoptions but I don't know what. Forget the fact that I am making a Google Charts call that I could just as easily render in sas, it is just an example.

PROC HTTP

Hi,

I never received any reply's to this posting and so I decided to go about figuring it out myself. 

First, I created a keystore using the 'keytools' application.  This is what I will use later to config Djavax.net.ssl

keytool -genkey -keyalg RSA -alias mycert

Second, I altered my config file to contain the following:

-jreoptions (-Dtkj.app.launch.config=!SASROOT/picklist

             -Dsas.app.class.path=/usr/local/SAS/SASVersionedJarRepository/9.2/eclipse/plugins/tkjava.jar

             -DPFS_TEMPLATE=!SASROOT/misc/base/qrpfstpt.xml

             -Djava.security.policy=!SASROOT/misc/base/sas.policy

             -Djava.security.auth.login.config=!SASROOT/misc/base/sas.login.config

             -Djava.class.path=/usr/local/SAS/SASVersionedJarRepository/9.2/eclipse/plugins/sas.launcher.jar

             -Djava.system.class.loader=com.sas.app.AppClassLoader

             -Dsas.ext.config=!SASROOT/misc/base/sas.java.ext.config

             -Djavax.net.ssl.trustStore=/home/&sysuserid/.keystore

             -Djavax.net.ssl.trustStorePassword=q1w2e3)

This link was helpful but somewhat incomplete in explaining what needed to be done.

Thanks,

Re: PROC HTTP

I am getting the same three ERROR messages, and I'm not trying an https connection, just a simple HTTP GET within the firewall, just to see if this will work, so I'm thinking the keystore setup is not necessary in my case.

When I look in my SAS 9.2 installation, there is no tkjava.jar whatsoever. Does your installation have one at the path listed in your config file?

Also, my sas.launcher.jar exists in !SASROOT/misc/applets, not in the SASVersionedJarRepository/9.2/eclipse/plugins referenced in my config file (I didn't install SAS so I don't know what's going on with these eclipse-related entries).

Re: PROC HTTP

gkaupas,

It would be for you to consult with SAS tech support on this matter as altering these settings is not usually recommended.

Re: PROC HTTP

I wasn't asking for suggestions on changing the configuration settings, even though that's effectively what you were doing, although it clearly looks like our installation is corrupted and possibly needs tech support intervention.

I was just curious, as a preliminary step, whether your installation actually had a tkjava.jar file present anywhere, since the third error "Unable to load extension: (tkjava)" seems to be in reference to this.

Re: PROC HTTP

tkjava.jar part of the SAS Foundation install of JAVA.  If you use linux and install SAS in the default path you will find the file here: /usr/local/SAS/SASVersionedJarRepository/9.2/eclipse/plugins/tkjava.jar

I am not a Windows user so I do not know the relative path for an installation there, but I beleive it is C:\PROGRA~1\SAS\SASVER~1\9.2\eclipse\plugins\TKJAVA~1.000\tkjava.jar.  The reason you are probably experiencing these issues is because you are missing the -Dsas.app.class.path parameter in your SAS system option JREOPTIONS.  This problem and the problem I had are not due to 'corrupt' installations, but rather incorrect configurations in the system enviorment/sas enviornment.  Consider creating a copy of your current config file and using the following JREOPTIONS:

-JREOPTIONS=(

  -Dsas.jre.libjvm=C:\Program Files\Java\jre1.5.0_12\bin\client\jvm.dll

  -Djava.security.policy=!SASROOT\core\sasmisc\sas.policy

  -Dsas.ext.config=!SASROOT\core\sasmisc\sas.java.ext.config

  -Dsas.app.class.path=C:\PROGRA~1\SAS\SASVER~1\9.2\eclipse\plugins\TKJAVA~1.000\tkjava.jar

  -DPFS_TEMPLATE=!SASROOT\core\sasmisc\qrpfstpt.xml

  -Djava.class.path=C:\PROGRA~1\SAS\SASVER~1\9.2\eclipse\plugins\SASLAU~1.000\SASLAU~1.JAR

  -Djava.system.class.loader=com.sas.app.AppClassLoader

  -Djava.security.auth.login.config=!SASROOT\core\sasmisc\sas.login.config

  -Dtkj.app.launch.config=!SASROOT\picklist )


This should be the default JRE configurations for Windows install of SAS Foundation.  This also assumes you are using the default version of JAVA for your SAS Installation: 1.5.0_12.


You may also want to check that your OS environment contains all the appropriate information.

In command prompt check if echo %JDK_HOME% returns anything.

Check the $SAS_CONFIG\Lev1\level_env.bat file and see if maybe this variable is assigned here for by SAS if not.  Or the file C:\Program Files\SAS\sassw.config

Check also for JREHOME and VJRHOME variable.

Consider posting a question in the SAS Deployment section of the forum here for additional responses from people more adept with SAS Installations and Configurations under Windows.

Re: PROC HTTP

Thanks ... I'm actually on an antique server running SunOS 5.8, so it's possible something isn't supported or the Java part wasn't all there or didn't install right. I will take it up with my on-site SAS rep and we'll follow up with tech support from there.
