create a list of key/value pairs

I am not sure if the following is doable:

I have say a hashmap - key:"1" value: "one".

I want to convert this hashmap to a list - ["1":"one"]

Is this doable?

count(*) and groupby - Projections

I have a query

I am trying to use Hibernate detached criteria and have the following code:

This generates the above query with count(*). What should i add to get the count(*) in the query?
I tried projectionsCriteria.setProjection(Projections.count("column1")); and
projectionsCriteria.setProjection(Projections.rowCount());

that does not work. Any ideas?

sql-query and entity-name in .hbm.xml file

I have a sql-query which returns a resultset ref as:

In the same hbm file, i have two definitions of Cat Bean.

With the above code, I get an error on startup. Is there a way that the resultset ref can point to the (2) bean instead of (1)?

IE6 - Remove cookies using java or javascript

Hi,

I am facing the following issue:

when i login to my application, i am setting the value of a cookie. Cookie name = TESTCOOKIE.
When i logout, say the click of a link, i am programmatically removing the cookie as follows:

If i dont close the browser window and tried to login again, i see the following:

TESTCOOKIE

TESTCOOKIE=5130015848645758769

The second value is the expected value. I understand that the first value is because of me deleting the cookie.
I see this happening in IE6 only. Can anybody let me know, if i can remove the first TESTCOOKIE from the list.

Because of two cookies with the same name, i am unable to login to the application again.

Adding <pre> to an xml file

Paul,

Thank you for the reply. Could you point me to some examples which would help me do this.
Also, i dont want to add a tag.

I want to add as text inside the body tag. It would be an awful amount of existing java code change if i add it as a tag. that is why.
i tried searching for xslt add text...but didnt find any.

Adding <pre> to an xml file

I have an xml file as follows:

I need to transform the text in body tag and append the pre tag...something like:

I have tried something like this:

This works fine. However, this is actually copying the xml structure first in memory and then recreating the entire xml.
Is there a way in xslt i could navigate to the required node and append <pre> within the body tag. Essentially i am thinking if there is a clean way to do it.

error while mapping to child table directly

Ok..i do understand what you are saying...but if you remove the alias, how would i supply articleId & attachmentName as restrictions to the detached criteria.

I tried :

It still tries to look for articleId in articleAttachments, whereas it is actually present in ArticleAttachmentsId.

error while mapping to child table directly

The articleId is present in ArticleAttachmentsId bean, a composite key in article_attachments table.
If I were to remove the alias, how would I let the bean know to look for articleId and attachment name in articleattachmentsid bean.

The attachment itself , a byte[] is in articleattachments bean.

I also tried this approach:

Here again i get the same exception as above.

Object Relational Mapping

error while mapping to child table directly

I have the following scenario:

Article table, which has all article related information.
A article can have one or more attachments, stored in article_attachments table.
Article_attachments has composite key for which we have articleAttachmentsId bean.

Following is the mapping in hbm.xml file:

articleattachments and articleattachmentsid bean are as follows:

public class ArticleAttachmentsId implements Serializable {
private Long articleId;
private String attachmentName;
public ArticleAttachmentsId(){}
public ArticleAttachmentsId(Long articleId, String attachmentName){
this.articleId=articleId;
this.attachmentName=attachmentName;
}
public Long getArticleId() {
return articleId;
}
public void setArticleId(Long articleId) {
this.articleId = articleId;
}
public String getAttachmentName() {
return attachmentName;
}
public void setAttachmentName(String attachmentName) {
this.attachmentName = attachmentName;
}
public String toString(){
StringBuffer sb = new StringBuffer();
sb.append(" articleId="+articleId);
sb.append(" attachmentName="+attachmentName);
return sb.toString();
}
}
public class ArticleAttachments implements Serializable{
private static final long serialVersionUID = -1893810557780172873L;
private ArticleAttachmentsId id;
private byte[] attachment;
public ArticleAttachments(){}
public ArticleAttachments(ArticleAttachmentsId id,byte[] attachment){
this.id=id;
this.attachment=attachment;
}
public ArticleAttachmentsId getId() {
return id;
}
public void setId(ArticleAttachmentsId id) {
this.id = id;
}
public byte[] getAttachment() {
return attachment;
}
public void setAttachment(byte[] attachment) {
this.attachment = attachment;
}
public String toString(){
StringBuffer sb = new StringBuffer();
sb.append(" MsaArticleAttachId="+id);
sb.append(" attachment="+attachment);
return sb.toString();
}
}

I know the articleId and attachmentname and would like to retrieve the ATTACHMENT from the table. I wrote the following code:

I get the following exception:

Caused by: org.hibernate.QueryException: could not resolve property: articleId of: com.mhc.sandp.msa.app.beans.article.ArticleAttachments

Dont understand y it is searching for articleId in articleAttachments table, when i have created an alias? also trying to see if there is a resolution to this problem.
Please help. Any ideas.

Thank you!

Java in General

Write UISpec4j Unit Test for a class

I have two scenarios:

1- An orderEntry class, which is an event listener class. No constructor defined. Does not extend JPanel/JFrame. This class is defined as a bean and is initialized by spring application context.
2- An AgentMonitorBrowser class, which extends JPanel. No constructor defined. Again, same as (1), it is defined as a bean and initialized by spring app context.

Any ideas on how one could write UIspec4j unit test cases for the above cases. I have tried all searches on google and i only find myself in circles, with the same examples around.

I also took a look at abbot and I face the same issue there again....

Any ideas please?

Swing GUI Testing Framework

I am on the lookout for a Swing GUI testing framework. I did try UISpec4j, however, i see that the major disadvantage is I could write unit tests only for classes, which extend a JFrame/JPanel.
I was reading on JFCUnit, however, I am not sure if it is still supported.

Any suggestions/ideas?

I have some classes like these -

public class AgentMonitorBrowser extends JPanel implements WorkstationConfigSupport, ActionListener {
abstract class MyAction {
abstract void performAction(ExecutionPlatformService service, AgentMonitorInfo ami, Object...params);
}
class SetAgentPropertyAction extends MyAction {
void performAction(ExecutionPlatformService service, AgentMonitorInfo ami, Object... params) {
executionPlatformService.setAgentProperty(ami.getMeasureName(), ami.getName(),
(String) params[0], params[1]);
}
}
class CancelOrderAction extends MyAction {
void performAction(ExecutionPlatformService service, AgentMonitorInfo ami, Object... params) {
executionPlatformService.cancelOrderForAgent(ami.getMeasureName(), ami.getName());
}
}
public AgentMonitorBrowser() { .....}
--------------------------
public class OrderEntry implements ActionListener, PropertyChangeListener {
public JPanel createPanel() {
JPanel main = new JPanel(new GridLayout(3,1));
//Top Panel
JPanel o = new JPanel(new FlowLayout());
quoteSymbolLabel = new JLabel("Quote");
quoteSymbolField = new JFormattedTextField("");
.......
}

I am interested in writing unit tests for these swing based java classes.
