ApacheJserv and XtShellStrings

[valise]

I have this error when I try to use my servlets which are supposed to
generate a graphic:

/usr/local/jdk1.7/bin/../lib/i686/green_threads/libawt.so: undefined
symbol: XtShellStrings (libawt.so)
java.lang.UnsatisfiedLinkError: no awt in shared library path
at
org.apache.jserv.JServConnection.processRequest(JServConnection.java:341)

at
org.apache.jserv.JServConnection.run(JServConnection.java:197)
at java.lang.Thread.run(Thread.java)

I put this line in jser.properties :

wrapper.env=LD_LIBRARY_PATH=/usr/local/jdk1.7/lib/:/usr/X11R6/lib/:/lib/

Have you any idea???

Thanks!
