Error "no db_java-4.1..."

[Lam Dang]

Running tests in /usr/local/src/IceJ-1.0.0 on RH8.0 , I got this error:

*** running tests in ./test/Freeze/cursor:

starting client... ok
Exception in thread "main" java.lang.UnsatisfiedLinkError: no db_java-4.1 in java.library.path

I was using Sleepy Cat's db-4.1.25 because it's the only one available at their download site. (I didn't remove the db4*-4.0.14-14 RPMs that came with RH 8.0. )

Here's my CLASSPATH:

.:/usr/local/src/IceJ-1.0.0/lib/Ice.jar:/usr/local/src/db-4.1.25/build_unix/db.jar

I'd already built the C++ version of Ice-1.0.0 and run its test suite without any error.

Any advice will be appreciated.

The Java version of BerkeleyDB is layered on the C version using JNI, therefore you must have the directory containing libdb_java-4.1.so in your LD_LIBRARY_PATH.

Hi,

You also need to add the directory containing the berkeley db shared libraries (such as libdb_java-4.1.so) to your LD_LIBRARY_PATH.

You can download the older distributions here:

Thanks for your quick responses. But going back to db4.0 and even db3.3 didn't seem to help. I got exactly the same error with them. Obviously it's something in my setup. I checked and rechecked the following:

- Ice.jar and db.jar in CLASSPATH

- libdb_java-[4.1, 4.0, 3.3].so in either LD_LIBRARY_PATH or in a directory (e.g., /usr/local/lib) included in /etc/ld.so.conf

- Rebooting a couple of times.

db4.0 should work for IceJ because it does work for Ice on the same box.

Any pointers will be appreciated.

Strange. Did you try any of the suggestions on Sleepycat's site?

Sorry I goofed! I didn't set LD_LIBRARY_PATH correctly.

The IceJ test suite ran OK with db-4.1.25, but failed at the first Freeze test with db-4.0.14. Here's my setup:

export CLASSPATH=.:/usr/local/src/IceJ-1.0.0/lib/Ice.jar:/usr/local/src/db-4.1.25/build_unix/db.jar
export LD_LIBRARY_PATH=/usr/local/src/db-4.1.25/build_unix/.libs
export ICE_HOME=/usr/local/src/Ice-1.0.0

Thanks for your help.
