If you want to preserve errors and messages across a redirect you can you

You definitely do not want to pass 'entry' as a parameter on the url.
Every database object needs some kind of unique key id just for situations
like this.
Maybe you could use the insertDate as a key (it's probably unique within
this context) but it would be better to add a key, perhaps a sequence number
so that goalToAchieve_id + seq is the PK.

You are not providing enough information for anyone to help you. Since you
have changed your object and the jsp you had better include them with any
request.

@Table(name = "TableNameGoesHere")

//the java file would use ForeignKey annotation as described
@org.hibernate.annotations.ForeignKey(name = "FK_GOALTOACHIEVE_ID")

public class WikiDocument extends WikiFile<WikiDocument> implements Serializable {
  public String getHistoricalEntityName() {
    return "HistoricalWikiDocument";
  }

and the hibernate configuration file (DatabaseObjects.hbm.xml) would handle the SequenceGeneration

<hibernate-mapping package="org.jboss.seam.wiki.core.model" default-access="field">
  <class name="WikiDocument" entity-name="HistoricalWikiDocument" table="TABLE_NAME_GOES_HERE" polymorphism="explicit">
    <id name="PrimaryKey_In_Java_File" column="PRIMARY_KEY_ID">
       <generator class="org.hibernate.id.enhanced.SequenceStyleGenerator">
          <param name="sequence_name">TABLE_NAME_PRIMARY_KEY__SEQUENCE</param>
       </generator>
    </id>

WARNING: Despite (albeit brief) commentary offered
any attempts to provide SEQUENCE generation to subvert SEQUENCE GENERATION by DBA is discouraged ..you do'nt want 2 sequences on same Table
i would encourage you to coordinate your SEQUENCE generation activity with DBA

fwiw

Looks like you need to change entry.mark to just mark and remove the
<s:property value="%{entry}"/>. Also you probably don't need to pass both
the name and id of the parent object.

<a href="<s:url action='DeleteEntryForm' var="entry" escapeAmp="false">
    <s:param name="id" value="%{goalToAchieve.id}" />
    <s:param name="mark" value="%{mark}" />
 </s:url>
">Remove</a>

I'm not sure but do pls check out by including the sitemesh-2.3.jar file and xwork-2.0.6.jar file in your library

Subject: Migration from Struts1 to Struts2
To: user@(protected)
Date: Monday, July 13, 2009, 6:33 AM


Hi,

We have migrated struts1 application to struts2. But now once we
deployed the system the CPU is going 90% to 100% and system is getting
loaded. In JSP's we are not using struts specific tags or freemaker
templates. Our JSP files are just plain jsp files only with
requstScope variables.

We are using following versions of struts and dependent libraries.

struts2-core-2.1.6.jar
struts2-codebehind-plugin-2.1.6.jar
ognl-2.6.11.jar
freemarker-2.3.13.jar

Please let me know if we can do any improvement with out switching
back to struts1

Kind Regards
Lasantha
