java.lang.UnsatisfiedLinkError：没有GurobiJni / Tomcat [英] java.lang.UnsatisfiedLinkError: no GurobiJni / Tomcat
问题描述
我们正试图在CentOS中通过Tomcat服务器的Java Web应用程序运行Gurobi。系统变量已定义：
We are trying to run Gurobi through a Java web application with Tomcat server in a CentOS. System variables are defined:
declare -x GRB_LICENSE_FILE="/home/suporte/gurobi.lic"
declare -x GUROBI_HOME="/opt/gurobi752/linux64"
declare -x LD_LIBRARY_PATH="\${LD_LIBRARY_PATH}:\${GUROBI_HOME}/lib"
declare -x PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:\$JAVA_HOME/bin:\$GUROBI_HOME/bin"
Gurobi和Java工作正常。应用程序在Tomcat中运行良好，但是当它调用Gurobi时，我们得到异常：java.lang.UnsatisfiedLinkError：java.library.path中没有GurobiJni75。
Gurobi and Java work fine. Application works fine as well in Tomcat, but when it calls Gurobi, we get the exception: "java.lang.UnsatisfiedLinkError: no GurobiJni75 in java.library.path".
Exception in thread "Thread-14" java.lang.UnsatisfiedLinkError: no GurobiJni75 in java.library.path

有什么想法解决这个问题？
Any idea to solve the problem?
你可以将LD_LIBRARY_PATH设置为指向存储.so文件的Gurobi目录，以及存储.jar文件的目录。
You can set LD_LIBRARY_PATH to point to the directory of Gurobi where the .so files are stored, and also the directory where the .jar files are stored.
您还可以制作Gurobi可以通过复制或链接从Tomcat访问jar文件。
You can also make Gurobi jar file accessible from Tomcat by copying or linking it.
ln -sv $GUROBI_HOME/lib/gurobi.jar $TOMCAT_HOME/lib/

尝试
declare -x LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${GUROBI_HOME}/lib"
而不是
declare -x LD_LIBRARY_PATH="\${LD_LIBRARY_PATH}:\${GUROBI_HOME}/lib"
使用\时出错，并且您没有复制/粘贴官方文档。
There is a mistake by using \ , and you didn't copy/paste the official doc.
要进一步调试，请使用此内容创建JSP，它显示所有系统属性a我们会看到java.library.path。很奇怪之前没有人发布这个。
For further debugging, create a JSP with this content, it displays all System properties and we'll see java.library.path. It's weird nobody ever posted this before.
<%@ page import="java.util.Properties" %>
<%@ page import="java.util.Set" %>
<%
Properties p = System.getProperties();
Set<String> keys = p.stringPropertyNames();
for (String key : keys)
out.println(key + " : " + p.getProperty(key));
%>

从调试JSP中我们看到 ld.library.path 正确指向您的GUROBI lib目录。
我们可以尝试为 java.library.path 添加系统属性。在您的Tomcat安装中，使用此内容编辑或创建 bin / setenv.sh 文件：
From your debug JSP we see that ld.library.path is correctly pointing to your GUROBI lib directory.
We can try adding a System Property for java.library.path. In your Tomcat installation, edit or create bin/setenv.sh file with this content :
CATALINA_OPTS="-Djava.library.path=/opt/gurobi752/linux64/lib/"
可以在此处阅读对此建议的解释。
An explanation to this suggestion can be read here.
btw我不知道你把声明-x 放在哪里，但将它们存储在bin / setenv.sh中是合理的
btw I don't know where you put your declare -x , but it would be legitimate to store them in bin/setenv.sh
这篇关于java.lang.UnsatisfiedLinkError：没有GurobiJni / Tomcat的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
