[UMN_MAPSERVER-USERS] Java Mapscript vs. Swig

[José Vilson de Mello de Farias]

Greetings,   I've compiled a Mapserver from the latest CVS code (Sept 29) and I'm having some problems with Java Mapscript.   My system had been running fine until this afternoon, when I compiled a new Mapserver from CVS code. I had to compile a new Swig version before I could start.   The Mapserver compilation was fine, and I didn't get any erros. My goal was the Java Mapscript, wich was sucessfully compiled and tested with "make test". After I had deployed and restarted the Tomcat it figured out that one of my example codes wasn't working anymore. The code is very simple, please take a look :   protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {     log.trace("doGet - request:" + req);     try {       PrintWriter p = resp.getWriter();       mapObj mapa = new mapObj("/home2/java/tomcat/webapps/mapserver_wms/mapas/rio_grande_do_sul.map");       mapa.setMappath("/home2/java/tomcat/webapps/mapserver_wms/mapas/shapes_rio_grande_do_sul");           imageObj image = mapa.draw();       File arqMapa = File.createTempFile("mapa", ".png", new File("/home2/java/tomcat/webapps/mapserver_wms/image"));       log.debug("createTempFile " + arqMapa.getAbsolutePath());       arqMapa.deleteOnExit();       image.save(arqMapa.getAbsolutePath(), mapa);       resp.setContentType("text/html");       resp.getWriter().println("<img src="" + arqMapa.getName() +  ">");     }     catch (Exception e) {       log.error(e.getLocalizedMessage(), e);     }   } After I executed the code above on Firefox, the following error was showed : javax.servlet.ServletException: set_mapObj_mappath     org.apache.catalina.security.SecurityUtil.execute(SecurityUtil.java:293)     org.apache.catalina.security.SecurityUtil.doAsPrivilege(SecurityUtil.java:161) root cause java.lang.UnsatisfiedLinkError: set_mapObj_mappath     edu.umn.gis.mapscript.mapscriptJNI.set_mapObj_mappath(Native Method)     edu.umn.gis.mapscript.mapObj.setMappath(mapObj.java:195) After some tests I found that the problem had been caused by mapa.setMappath code. It seems Swig wasn't able to create a proper mapscript.jar/libmapscript.so. I checked the mapscript_wrap.c and the corresponding method to mapa.setMappath was called Java_edu_umn_gis_mapscript_mapscriptJNI_mapObj_1mappath_1set. Although I have definitely no experience with Swig, those numbers "1" in method name doesn't look ok. Is it ok? Could be the Swig the responsible for this error? If I remove the mapa.setMappath, everything works fine and my map is shown in the browser. I included some info about my Mapserver and system. By the way, I've compiled every component of Mapserver instead of using Linux defaults. compiled packages (we haven't used any RPMs, all packages were manually compiled/installed) libpng-1.2.12 freetype-2.2.1 zlib-1.2.3 gd-2.0.33 jpegsrc.v6b tiff-3.8.2 libgeotiff-1.2.1 PDFlib-Lite-6.0.3 proj-4.4.9 curl-7.15.4 geos-2.2.3 gdal-1.3.2 swig-1.3.29 Mapserver's configure ./configure --prefix=/home2/mapserver --without-pdf --with-threads --with-zlib=/home2/mapserver/zlib --with-png=/home2/mapserver/libpng --with-tiff=/home2/mapserver/libtiff --with-jpeg=/home2/mapserver/libjpeg --with-freetype=/home2/mapserver/freetype --with-proj=/home2/mapserver/proj4 --with-geos=/home2/mapserver/geos/bin/geos-config --with-gd=/home2/mapserver/gd --with-ogr=/home2/mapserver/gdal/bin/gdal-config --with-gdal=/home2/mapserver/gdal/bin/gdal-config --with-curl-config=/home2/mapserver/libcurl/bin/curl-config --with-wfs --with-wcs --with-wmsclient --with-wfsclient --with-php=/usr/include/php Linux Linux dgtad 2.6.9-22.EL #1 Mon Sep 19 18:20:28 EDT 2005 i686 athlon i386 GNU/Linux MAPSERVER_HOME=/home2/mapserver PROJ_LIB=$MAPSERVER_HOME/proj4/share/proj LD_LIBRARY_PATH=$LD_LIBRARY_PATH::/home2/mapserver/proj4/lib:/home2/mapserver/gdal/lib:/home2/mapserver/geos/lib:/home2/mapserver/libcurl/lib:/home2/mapserver/libpng/lib:/home2/mapserver/libjpeg/lib:/home2/mapserver/libtiff/lib:/home2/mapserver/libgeotiff/lib:/home2/mapserver/ogdi/lib:/home2/mapserver/freetype/lib:/home2/mapserver/gd/lib:/home2/mapserver/zlib/lib:/home2/mapserver/proj4/share/proj:$MAPSCRIPT_HOME MAPSCRIPT_HOME=$MAPSERVER_HOME/mapscript PATH=/usr/java/jre/bin:/usr/java/jdk/bin:$MAPSCRIPT_HOME Java JRE_HOME=/usr/java/jre JAVA_HOME=/usr/java/jdk JDBC_HOME=/usr/java/jdbc CATALINA_HOME=/usr/java/tomcat java version "1.5.0_07" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03) Java HotSpot(TM) Client VM (build 1.5.0_07-b03, mixed mode, sharing) Tomcat Using CATALINA_BASE:   /usr/java/tomcat Using CATALINA_HOME:   /usr/java/tomcat Using CATALINA_TMPDIR: /usr/java/tomcat/temp Using JRE_HOME:       /usr/java/jre Server version: Apache Tomcat/5.5.17 Server built:   Apr 14 2006 02:08:29 Server number:  5.5.17.0 OS Name:        Linux OS Version:     2.6.9-22.EL Architecture:   i386 JVM Version:    1.5.0_07-b03 JVM Vendor:     Sun Microsystems Inc. gcc gcc (GCC) 3.4.4 20050721 (Red Hat 3.4.4-2) Copyright (C) 2004 Free Software Foundation, Inc.
