Hello all,I`m a computer science student from Frankfurt/main (germany). Our student team (10 students) are working on a R/Interface project (Java and R) and we have a problem with R and JRI. We are working on 10 computers with Windows XP SP2, R 2.8.0, jdk1.6.0_11and the same classpath setttings but our application works only on two computers. We can't explain us this.----------------------- This is the error message:Cannot find JRI native library! Please make sure that the JRI native library is in a directory listed in java.library.path. java.lang.UnsatisfiedLinkError: no jri in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682) at java.lang.Runtime.loadLibrary0(Runtime.java:823) at java.lang.System.loadLibrary(System.java:1030) at org.rosuda.JRI.Rengine.<clinit>(Rengine.java:9) at net.datenanalyse.iedae.rinterface.RInterface.<init>(RInterface.java:20) at net.datenanalyse.iedae.rinterface.Start.main(Start.java:9) Java Result: 1 -----------------OK, we know that we have same .dll reference problems. In the first step we copied all necessary .dlls into the system32 folder and checked that we fix all reference problems. No changes… After this step we set the Classpaths to \Java\jdk1.6.0_11\bin and \R\R-2.8.0\bin. No change, the error message is the same. Do you have from an faq, idea or a guide to install the JRI? Sorry for my bad English but I hope you understand me. Thank you, Stefan
Not the solution but a few hints. The library path is not the same as the classpath. You can get the library path by:
System.out.println("JLP =" + System.getProperty("java.library.path");
Maybe have a look at java.lang.System, especially load, loadLibrary and
setProperty.
