外部jsp获取数据插入数据库中问题

FormProcess formProcess = new FormProcessBean();
                        Form form = (Form) formProcess.doView(formId);
                        ParamsTable ptable=new ParamsTable();
                        System.out.println("**************打印名称1+++++++++++"+ps.getPname());
                        System.out.println("**************打印姓名==+++++++++++"+ps.getEname());
                        System.out.println("**************打印ptable**************"+ptable);
                        DocumentProcess documentProcess = (DocumentProcess) DocumentProcessBean.createMonitoProcess(applicationId);
                        System.out.println("**************打印documentProcess+++++++++++"+documentProcess);
                         
                        Document document = (Document) documentProcess.doNewWithOutItems(form,webUser,new cn.myapps.base.action.ParamsTable());


                        document.findItem("名称1").setValue(ps.getPname());
                        document.findItem("编号").setValue(ps.getPnum());
                        document.findItem("文件编号").setValue(ps.getPfilenum());
                        document.findItem("单位").setValue(ps.getPcompany());
                        document.findItem("负责人").setValue(ps.getPperson());
                        document.findItem("联系人姓名").setValue(ps.getEname());
                        document.findItem("联系人性别").setValue(ps.getSex());
                        document.findItem("学历").setValue(ps.getEducation());
                        document.findItem("专家职称").setValue(ps.getTitle());
                        document.findItem("联系人从事专业").setValue(ps.getJob());
                        document.setApplicationid(applicationId);
                        document.setDomainid(domainId);
                        //保存表单信息
                        documentProcess.doCreateOrUpdate(document,webUser);

通过调用平台数据库连接方法，用doCreateOrUpdate将数据更新至数据库表中，但总是报Document document = (Document) documentProcess.doNewWithOutItems(form,webUser,new cn.myapps.base.action.ParamsTable());
这一行错误。

错误信息如下所示：
**************打印ptable**************{}

您好，上面的脚本是在平台中写的。如果您需要在jsp中不能这样用的。如果您这边有源码可以去看下。对应可以看下/obpm/src/main/java/cn/myapps/core/dynaform/document/ejb/DocumentProcess.java类中的doNewWithOutItems方法。
