I recently installed subsonic, which has a Java dependency. The www\/subsonic port installed Java.<\/p>\n

Unfortunately, this (or something else I did) broke CrashPlan (which uses the Linux Java in the java\/linux-sun-jre16 port).<\/p>\n

I had to take a few unexpected steps to fix this.
\n
\nNamely:<\/p>\n

Re-install linux-sun-jre16<\/h3>\n

I’m not sure if this was necessary, but I did it to make sure that the Linux Java didn’t get over-written by the native Java. It didn’t. Linux Java installs in a different directory (see below).<\/p>\n

Link the linux java to the Linux compat directories<\/h3>\n

The Linux Java gets installed in \/usr\/local\/linux-sun-jre1.6\/<\/code>. However, the \/compat\/linux\/bin\/bash<\/code> shell will pick up the native java. I have no idea how this all worked before I installed native Java, but I linked all the java files to the compat linux bin directory:
\n
\nln -s \/usr\/local\/linux-sun-jre1.6\/bin\/* \/usr\/compat\/linux\/usr\/local\/bin
\n<\/code><\/p>\n

Fix up Java class paths<\/h3>\n

For whatever reason, CrashPlan would start at this point but would not be able to load jtux<\/code>. I added the following to the CrashPlanEngine script (in \/usr\/compat\/linux\/usr\/local\/crashplan\/bin):
\n
\n FULL_CP=”${TARGETDIR}:${TARGETDIR}\/lib\/com.backup42.desktop.jar:${TARGETDIR}\/lang”
\n<\/code><\/p>\n

Basically, it was missing the direct \/lib directory. Again, I’m not sure why this wasn’t a problem before.\n<\/p>\n
