Add custom data source to Jaspersoft Studio

时间秒杀一切 提交于 2019-12-01 03:15:02
I am trying to fill a table by passing a custom data source to it. I have created a simple report with a table on it. The report it self gets the data from a ms sql database. I have written a java class similar to the class in this Example . But I get no value in table. At the example there is no scriptlet. I have checked the (String) this.getFieldValue("KN_FormelGG"); line of code. It gets the data from field and can show it on report. So I guess the bean data source is not filled. I call the fill Table method in a afterGroupInit . How can I use Collection of data from java in jasper? I tried

问题 I have been trying to learn about the Java beans in WebSphere Commerce but I got really confused. Please help me out. I need to know: What is the difference between EntityBean , SessionBean , DataBean and AccessBean and how do they compare? Though I found the difference between Session and Entity, and between Access and Data, I fail to understand how they are all related to each other. All the help would highly be appreciated. 回答1: The entity bean represents a java bean which is coded by EJB

How to set Class value to spring bean property?

会有一股神秘感。 提交于 2019-12-01 02:27:53
Hey, what is the best way to set a bean's property with Class value ? Regarding XML configuration. For a bean like this : public class FilterJsonView extends MappingJacksonJsonView { private Set<String> filteredAttributes; private Class clazz; public Set<String> getFilteredAttributes() { return filteredAttributes; } public void setFilteredAttributes(Set<String> filteredAttributes) { this.filteredAttributes = filteredAttributes; } public Class getClazz() { return clazz; } public void setClazz(Class clazz) { this.clazz = clazz; } } skaffman Just inject the class name, and Spring will convert it

If I have a class with non-primitive public members and I want to populate them from a CSV file with OpenCSV, how can I do this?

Person{ private String name; private Address al public void setAddress(Address a){..} public void setName(String name){..} } Addess{ private String line1; private String line2; private String postCode; . . . } CSV file: NAME | ADDR1 | ADDR2 |

Programming difference between POJO and Bean

醉酒当歌 提交于 2019-11-30 23:51:28
I have the following two classes. Can I say the first one is a POJO class and the second one as a Bean class? 1) POJO class, since it has only getter and setter method, and all the member are declared as private public class POJO { private int id; private String name; public int getId() { return id; } public String getName() { return name; } public void setId() { this.id = id; } public void setName() { this.name = name; } } 2) Bean class - all the member variables are private, has getters and setters and implements Serializable interface public class Bean implements java.io.Serializable {

Does EL automatically convert/cast the type? How does ${a.name} actually work?

南笙酒味 提交于 2019-11-30 22:45:20
I have a variable declared as type Object a which actually refers an instance of type A . In EL, I can directly use the following expression to print the name property of type A : ${a.name} How does it work? BalusC EL uses reflection under the hoods, usually via javax.beans.Introspector API . This is what it roughly does under the covers on ${a.name} . // EL will breakdown the expression. String base = "a"; String property = "name"; // Then EL will find the object and getter and invoke it. Object object = pageContext.findAttribute(base); String getter = "get" + property.substring(0, 1)
