@Bear Bibeault: I see, I thought you were trying to say that each time I need some jar to output its logging through Tomcat, I need log4j to be on the classpath.

I was actually wondering too which forum should be the best for posting this. So yes, if you think it has more to do with Spring, please move this thread to there. Thank you for this and for your answers!

@Bear Bibeault: Why does log4j need to be in the classpath? AS far as I know, Spring uses Commons logging (JCL), so if there's no log4j on the classpath, it will use the JDK logging API (java.util.logging).

As I said, when I remove log4j from the classpath, the logging for some of the jars works (e.g. JSF jars), for others it doesn't (e.g. Spring jars). I wonder why. Any ideas?

Also, I am using log4j.xml to config log4j.

Changes to the conf/logging.properties do take effect. I am expecting to get the logging at the file ${catalina.home}/logs/catalina.log

Here is my conf/logging.properties:

handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler .handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler 1catalina.org.apache.juli.FileHandler.level = ALL 1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs 1catalina.org.apache.juli.FileHandler.prefix = catalina java.util.logging.ConsoleHandler.level = ALL java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter ############################################################ org.springframework.level = ALL javax.faces.level = ALL com.sun.faces.level = ALL org.hibernate.level = ALL 1catalina.org.apache.juli.FileHandler.rotatable = false org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/my-webapp].level = ALL org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/my-webapp].handlers = 1catalina.org.apache.juli.FileHandler

My log4j.xml:

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <!-- MDM_LOGS Appender --> <appender name="APP_LOGS" class="org.apache.log4j.DailyRollingFileAppender"> <param name="Append" value="true" /> <param name="File" value="C:/storage/logs/my-webapp.log" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n" /> </layout> </appender> <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender"> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n" /> </layout> </appender> <category name="com.my.app" additivity="false"> <priority value="ALL" /> <appender-ref ref="APP_LOGS" /> </category> <!-- Category Section End --> <!-- ======================= --> <!-- Setup the Root category --> <!-- ======================= --> <root> <priority value="INFO"/> <appender-ref ref="CONSOLE"/> </root> </log4j:configuration>

On Tomcat, I am trying to get the logging output from the Spring libraries that I am using on my project.

My problem is that I am not getting the FINE logging from Spring. However, for other libraries such as JSF, I do get the FINE logging. What am I doing wrong?

I have noticed that when I remove log4j.jar from the classpath, I do get logging from Spring. But when I add log4j.jar to the classpath, the logging from Spring is gone. Can you explain why?

BTW I do need log4j and commons-logging(JCL) in my classpath, since some of the other jars I am using, refer to log4j and JCL explicitly in their code.

Here are the settings I am using, in Tomcat's conf/logging.properties:

.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler java.util.logging.ConsoleHandler.level = ALL 1catalina.org.apache.juli.FileHandler.level = ALL #this does not change the logging level... org.springframework.level = ALL # this does change the logging level... javax.faces.level = ALL com.sun.faces.level = ALL

Thank you guys!

Is there in one of the specifications any reference to methods that start with "is", while the suffix of the method's name is a property's name (similar to getter/setter methods)?

I was trying to find out an explanation about it but search engines omit the word "is".

Thanks!

I have a Book class which has properties such as id (long), name (String). Also, one of its properties is

Set<Author>

Author has properties such as id, name, biography.

I have a book search form in which the total set of the Authors in my DB appears in a multi-select box. I was able have the authors that were selected by the user sent correctly to the controller (i.e. I could get them through the command as Set of Authors), but I want the next page (i.e. the result view page, which is the same page as the first search page) also to show the original search form filled with the values that were selected by the user. This was easy with regular text fields, e.g. the book's name: in the controller I got them loaded on the command object, and I simply kept them unchanged before sending the same command object to the view. But keeping the command's Set of Authors did not cause the view page to pre-select the relevant Authors in the multi-select box.... HOW DO I DO THIS TRICK???

I have read in the following stackOverFlow link

Spring MVC JSTL preselected list

that I need to "to override the equals method of the" Author class.... I did it (two Author classes are equal if they have the same id), but it did not help. Still, no Author is selected in the multi-select box in result page after I submit the search form.

Thanks!

You can carry the parameters with a Get or Post request. Which one would you choose?

Regarding the session - there's an option to delete some variables when they time out.

I am writing a pagination method for a search form. The user will fill out the form, stating according to which parameters they want to search to be performed (there are about 20 parameters), and then if there are more results than could fit into one page, they will get the 10 first results with an index to let them skip to the next pages (like they do in Google search).

I am trying to figure out what is the best way to keep the search parameters between the result pages... URL (get) parameters, or session parameters?
Or do I have other ways to do it in the Spring framework?

I am trying to figure out what is the best way to write the HQL statement for the following scenario:

I have a class Book which has a property of the type Set<Author>. The class Author has properties such as name, etc.

Now my DAO method gets "Set<Author> authors" as a parameter. For this method I want to write an HQL query so I could get all the Books that at least one of their Authors is found in authors.

What is the best way to accomplish this?

Thanks!

Thank you guys.

I have seen this code snippet:

BeanWrapper company = BeanWrapperImpl(new Company());

http://static.springsource.org/spring/docs/3.0.0.RC1/spring-framework-reference/html/ch05s04.html

How could this work? As far as I know it's only allowed to call a constructor after the "new" keyword.

I am trying to bind a multiple <select> in a JSP page to a Set collection in the command object.

The code works when I use the older version of Spring (i.e. without annotations), but some things do not work when I am using the newer version of Spring (i.e. with annotations).

The older code that does work:

protected void initBinder(HttpServletRequest request, ServletRequestDataBinder dataBinder) throws Exception { dataBinder.registerCustomEditor(Set.class, "categories", new CustomCollectionEditor(Set.class) { protected Object convertElement(Object element) { String id = null; if (element instanceof String) { id = (String) element; } return id != null ? categoryDAO.get(Long.valueOf(id)) : null; } }); }

Using it in the JSP page:

<tr> <td>Categories :</td> <td><form:select path="categories" multiple="true"> <%-- <form:option value="0" label="Select" /> --%> <form:options items="${coupon.categoryList}" itemValue="id" itemLabel="name" /> </form:select></td> <td><form:errors path="categories" cssClass="error"/></td> </tr>

The JSP above works fine, because the the options of the <SELECT> show both the value and the label.

However the following newer initBinder does not fully work, because for the same JSP, the value of each option in the <SELECT> is empty (the HTML shows value=""). It does show the label.

@InitBinder public void initBinder(WebDataBinder dataBinder) { dataBinder.registerCustomEditor(Set.class, "categories", new CustomCollectionEditor(Set.class) { protected Object convertElement(Object element) { String id = null; if (element instanceof String) { id = (String) element; } return id != null ? categoryDAO.get(Long.valueOf(id)) : null; } }); }

Here is the code for Category:

@Entity @Table(name="CATEGORY") public class Category implements Comparable { public Category() {} public Category(Long id, String name) { super(); this.id = id; this.name = name; } private Long id; private String name; @Id @GeneratedValue @Column(name="CATEGORY_ID") public Long getId() { return id; } public void setId(Long id) { this.id = id; } @Column(name="CATEGORY_NAME") public String getName() { return name; } public void setName(String name) { this.name = name; } public int compareTo(Object anotherCategory) throws ClassCastException { if (!(anotherCategory instanceof Category)) throw new ClassCastException("A Category object expected."); return this.getId().intValue() - ((Category)anotherCategory).getId().intValue(); } }

Please help me understand why the initBinder does not fully work when I am using annotations.

Thank you for your time!

Why didn't you upgrade that jar to 3.0.5?

Also, just so you know, the Controller interfaces have been deprecated over the preferred approach of using Annotations in your POJO Controllers.

I did not upgrade org.springframework.transaction because I did not find something like spring-transaction in the repository....

http://shrub.appspot.com/maven.springframework.org/release/org/springframework/

I know the controller interfaces are deprecated now.. I was thinking to upgrade them at some point in the near future. However as far as I know they still should basically work in 3.0.5... is this not the case? They are included in the jars.

Also, I have another question regarding these jars... some repositories have these jars with the older(?) package names. Like here:

http://repository.opencastproject.org/nexus/content/repositories/com.springsource.repository.bundles.release/org/springframework/

Why do they do it and who actually distributes Spring with two different sets of jar names? The same version of Spring (3.0.5.RELEASE) appears in the first repository with names like spring-XXX-3.0.5.RELEASE while in the second repository these jars appear with names like org.springframework.XXX-3.0.5.RELEASE.
Also, I have noticed that the servlet jar appears as "webmvc" in the first repository and as "web.servlet" in the second repository.

The 10 jars in bold are the ones I've upgraded. As you can see my code does not work anymore after the upgrade.

Did you mean

?

I cannot see how it might change to result. But I tried it and I still get the

Is there any place where I could check what went wrong?
