Unsupported major.minor version 49.0

[Former Member]

I have Development Server and NWDI server at EP7 Sp18

The java version on both the systems is we have java 1.4_2_18-b06

From my NWDS, if i directly deploy the application on the server it works fine, but if i use the Deirect Deployment option on NWDI, i get the following Error

java.lang.UnsupportedClassVersionError: bhi/com/comp/wdp/InternalResubPrnrReqComp (Unsupported major.minor version 49.0)

I am wondering if this is issue with my local java version on NWDS which is 1.4_2_17. But if that was the case, even direct deployment shouldn't work

Regards,

We tried the following approach to solve this:

There are two JDKs installed on NWDI server. 1.4.2_18 for EP70, and 1.5.0_17 for CE7.1

As recommended in help.sap

http://help.sap.com/saphelp_nw04s/helpdata/en/b5/7a5e4088dc0272e10000000a155106/frameset.htm

Set two variables for two different java homes

the variables are entered like

JDK1.5.0_HOME=/usr/j2se/j2se_1.5.0/j2se_1.5.0_17 ; JDK1.4.2_HOME=/usr/j2se/j2se_1.4.2/j2se_1.4.2_19 ;

i have defined the com.sap.jdk.home_path_key = JDK1.4.2_HOME as build variant in my track.

Now when i am activating a component, i am getting an error

legacy mode.

Error: Build stopped due to an error: No JDK_HOME_PATH defined for key 'JDK1.4.2_HOME'

Any idea what would cause that?

The issue was the default JDK was set to 1.5. We installed 1.4.2_19 jdk and added a java home variable in Component Build Service in Visual Admin. the same veriable was added as build variant on the track.

Not getting the error any more.
