在使用SuperMap Objects Java开发web应用时，当将应用部署到Tomcat中运行时，当调用Objects中的方法时，以ObjectsJava 7为例，如果不做特殊处理一定会报下面这个错：
java.lang.UnsatisfiedLinkError: no Wrapj in java.library.path这时请不要着急，在Tomcat中做一下简单处理即可：

1、打开Tomcat7/bin/catalina.bat，确认一下里面有没有如下内容：
rem Get standard environment variables如果没有的话在调用setclasspath.bat这个bat之前添加上述内容即可。
if not exist "%CATALINA_BASE%\bin\setenv.bat" goto checkSetenvHome
call "%CATALINA_BASE%\bin\setenv.bat"
goto setenvDone
:checkSetenvHome
if exist "%CATALINA_HOME%\bin\setenv.bat" call "%CATALINA_HOME%\bin\setenv.bat"
:setenvDone
2、打开setenv.bat，如果没有的话请手动创建。将其内容修改如下：
@echo off
rem set tmp variables ISERVER_ROOT
set BIN_DIR=%cd%
set curr=%cd%
cd ..
rem 下面这个路径根据实际情况进行修改set ISERVER_ROOT=D:\ProgramFiles\SuperMap\7_1_2\supermap_iserver_7.1.2_win64_deploycd %BIN_DIR%rem set JRErem if exist "%ISERVER_ROOT%\support\jre\bin\java.exe" set "JRE_HOME=%ISERVER_ROOT%\support\jre"rem if exist "%ISERVER_ROOT%\support\objectsjava\bin\com.supermap.data.jar" ( goto checkiServerUGO ) else ( goto checkPathUGO )rem check and set UGO in iServer\support:checkiServerUGOset "ObjectsJava_HOME=%ISERVER_ROOT%\support\objectsjava" set Path=%BIN_DIR%;%ObjectsJava_HOME%\bin;%Path%goto endrem check UGO in Path:checkPathUGOset /a n+=1for /f "delims=; tokens=%n% " %%a in ("%Path%") do ( if exist "%%a\com.supermap.data.jar" ( cd /d %%a\.. ) ) if %curr% NEQ %cd% ( set UGO_HOME=%cd% goto end ) else if %n% LEQ 255 ( goto checkPathUGO ) :endcd /d %BIN_DIR%
3、保存后启动Tomcat
现在再调用ObjectsJava中的方法，可以看到已经没有任何Wrapj.dll的问题了。
