For　secure　sharing　and　efficient　integration　of　finite　element　analysis　resources　(FEA),　the　FEA　grid　portal　based　on　Portlet　and　Globus　toolkit　4　(GT4)　was　presented.　The　two　layered　authentication　mechanism　of　the　grid　portal　system　was　implemented　by　combining　the　user　name/pass,　based　portal　layer　and　grid　security　infrastructure　(GSI)　based　service　layer　security　technologies.　The　job　management　method　was　established　by　adopting　the　grid　resources　allocation　and　management　(GRAM)　service　and　hierarchical　coordination　technology;　the　information　management　structure　was　presented　by　using　the　information　aggregation　technology　of　monitoring　and　discovery　service　(MDS)　and　the　information　collection　technology　of　Ganglia;　and　the　development　principle　of　GridSphere　based　Portlet　components　was　analyzed.　The　development　and　the　application　case　of　prototyping　grid　portal　system　demonstrates　that　the　Portlet　based　system　components　are　standardized,　reusable　and　quick　to　be　implemented,　and　the　portal　system　is　scalable　and　portable.
