[Former Member]

Hi,

I want to install SAP on solaris. I´ve installed de j2sdk 1.4.2_23 and declare it the Environment variable JAVA_HOME to this directory but I do java -version I get this

root@host # java -version

java version "1.5.0_21"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_21-b01)

Java HotSpot(TM) Server VM (build 1.5.0_21-b01, mixed mode)

What can i do?

Hello Ruben,

Please do echo $JAVA_HOME and double check.

Also please check if there are two directories under /opt:

java1.4 and java.1.5

Thanks for your answer,

In the E.V JAVA_HOME is declared this

root@host # echo $JAVA_HOME

/usr/jdk/j2sdk1.4.2_19

Under /opt there are not any directories wit 1.4.2 and 1.5.0, but in the directory /usr/jdk/ , yes. there are 2 directories.

You can have 2 versions of java without issues as long as the one you need is set with the env varibles...

Hello Ruben,

java -version would show the higher version of java however the installation would go with environmental variable value which is 1.4.2 in your case. That is the one you should use. Would not be an issue. I agree with Juan and can also say based on experience.

Anyways when you are using java -version which directory are you in ?

I just installed the j2sdk 1.4.2_23 on solaris x64 and when i have to put the path on the sapinst I put the path /usr/jdk/j2sdk1.4.2_23 and It´s erroneous. If i put the path of usr/java sometimes is correct.

whats under /usr/java?

Hi Ruben,

Just checked JAVA installation notes for Solaris.Apparently /usr/java is the default location. In case you already haven't just check this link to verify if the JAVA installation has been done properly:

If my solaris is an x86_64 what version of java I should keep?

The directory /usr/java is pointing to j2sdk 1.5.0. I declared the environment variables JAVA_HOME and SAPINST_JRE_HOME and always get the error.

When i execute the ./sapinst I get this :

/sapinst2/sapinst_exe.14521.1261595928/jre/bin/java* -Xmx256M -Dsap.env.var.javahome=SAPINST_JRE_HOME -cp /sapinst2/sapinst_exe.14521.1261595928/JAR/instgui.jar SDTServer rootdir=//.sdtgui config=jar:sdtserver.xml guiport=21212 httpport=4239 -nolock -srvarg=/SAPinstService/host=localhost -srvarg=/SAPinstService/port=21200 guistart=off

I push the path of java and get this message

Directory /usr/j2sdk1.4.2_23 is not a valid JDK directory: the java executable is missing.

I saw in this directory that are file missings.

Hello Ruben,

Just try declaring JAVA_HOME and not SAPINST_JRE_HOME and see if that works.

Also are installing ABAP alone or is JAVA stack also involved.

Also what are the sub directories under /usr/j2sdk1.4.2_23.

Regards.
