How to compile Web Dynpro DC with -source 1.4

[Amey-Mogare]

Hi,

I have installed SAP NWDS SP18 (previously I had SP15).

I am using KM APIs in my Web Dynpro DC and its not able to build it in NWDS SP18.

I get following build error:-

    [javac] Compiling 30 source files to C:\Documents and Settings\A171406\.dtc\LocalDevelopment\t\C196B8652AFFB25E7486C93C46A9FD14\classes
     [javac] ERROR: C:\Documents and Settings\A171406\.dtc\LocalDevelopment\t\C196B8652AFFB25E7486C93C46A9FD14\
gen_wdp\packages\com\amey\ldapp\components\ldacomp
\LdaComp.java:50: as of release 1.5, 'enum' is a keyword, and may not be used as an identifier
     [javac] ERROR: (try -source 1.4 or lower to use 'enum' as an identifier)
     [javac] ERROR: import com.sapportals.wcm.repository.enum.LinkType;
     [javac] ERROR:                                      ^
     [javac] 1 error

To resolve this, I went to following location and changed it to Java 1.4:-

Windows >> Preferences >> Java >> Installed JREs

But still I see that NWDS is picking up Java VM 1.5 only (may be based on following) :-

Windows >> Ant >> Runtime >> Classpath >>  u201DC:\Programs Files\SAP\IDE\IDE70\eclipse\plugins\org.apache.ant_1.5.3u201D >> ant.jar
Windows >> Ant >> Runtime Classpath>> u201DC:\Programs Files\SAP\IDE\IDE70\eclipse\plugins\org.apache.ant_1.5.3u201D >>  optional.jar
Windows >> Ant >> Runtime >> Classpath >> u201DC:\Program Files\Java\jdk1.5.0_16\libu201D >> tools.jar

Is there any way by which I can make my Java1.4 source code compile in NWDS SP18?

Please help.

Thanks and regards,

Hi,

change the JRE just for your DC, go to:

- context menu on your DC -> Properties -> Java Build Path -> Libraries

and change here JRE to 1.4

Hi Przemysław,

Thanks for reply.

Can see this when I go to "DC right-click >> properties >> Java Build Path >> Libraries"

JRE_LIB - C:\Program Files\Java\jdk1.5\jre\lib\rt.jar

What change do I have to make?

Thanks and regards,

Hi,

you have to use other variable that is pointing to Java 1.4 or create new one.

As you see, you are still using Java 1.5.

- select JRE_LIB and press Edit button on the right

- choose "Variable" button

- choose another variable which points to JRE 1.4 or create new one.

After that next build should be successfull.
