I initially wanted to migrate a JAVA EE project into maven. However, I ran into a dispatching error.
I got this stack trace in the file :

I added this dependency to my POM.xml (I thought that it's missing)
<dependency>
<groupId>org.apache.struts.xwork</groupId>
<artifactId>xwork-core</artifactId>
<version>2.2.1</version>
</dependency>
But I still have the error.
Can anyone tell me what I'm missing? Is it perhaps because I'm using Eclipse NEON1?
I have JDK1.7.0_71 and Websphere 7.0.0.
JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_71
MAVEN_HOME=D:\Maven\apache-maven-3.3.9
Caused by: java.lang.NoClassDefFoundError:
ognl.OgnlRuntime (initialization failure) at
You have missing OGNL dependencies on class path at run time.
The xwork-core is transitive dependency for struts2-core artifact.
OGNL is also transitive dependency.
Regarding the second error:
Response has been already commuted.
Struts is trying to return error result by using servlet response internally or forward to the error page by it can't do it if response has been commuted. The response becomes commuted as soon as the buffer is flushed. You should check the size of buffer on the response object and how much bytes has written to it.
javassist dependency was messing.
I added this dependeny on the POM file :
<dependency>
<groupId>javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.12.1.GA</version>
</dependency>
and it works for me.

I am attempting to use OCI Instance Principal authorization with Kafka Producer API to produce message to a OCI streams endpoint.
I am referring to the documentation provided here - https://docs.public.oneportal.content.oci.oraclecloud.com/en-us/iaas/Content/Streaming/Tasks/kafkacompatibility_topic-Configuration.htm
I run into the below issue that seems to indicate that the Jersey client instance is closed even as the attempt is being made to call the metadata service endpoint.

The container that executes this code is running within an OCI compute instance.
Can I get help to understand the cause of this issue?
Based on the example in the html/template documentation I can't say I fully understand why it appears that less and greater than are inconsistently escaped in my experiment:
https://golang.org/pkg/html/template/#hdr-Introduction
Does this warrant a bug report? I am holding off since I am relatively new to Go.
$ go version
go version go1.16 linux/amd64
I saw similar behavior with go1.15.8.
package main
import (
htmltemplate "html/template"
"os"
texttemplate "text/template"
)
type MyVars struct {
Flavor string
}
func main() {
Vars := MyVars{
Flavor: "##### html #####",
}
htmlTmpl, _ := htmltemplate.ParseFiles("index.html")
htmlTmpl.Execute(os.Stdout, Vars)
Vars = MyVars{
Flavor: "##### text #####",
}
textTmpl, _ := texttemplate.ParseFiles("index.html")
textTmpl.Execute(os.Stdout, Vars)
}
$ cat index.html
{{ .Flavor }}
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
< span >Hello< /span >
<span>Hello</span>
{{ "<" }}span{{ ">" }}Hello{{ "<" }}/span{{ ">" }}
$ ./experiment
##### html #####
<?xml version="1.0" encoding="UTF-8" standalone="no"?> # Why is only < escaped?
< span >Hello< /span > # Why is only < escaped?
<span>Hello</span> # Why is neither < nor > escaped?
<span>Hello</span>
##### text #####
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
< span >Hello< /span >
<span>Hello</span>
<span>Hello</span>
1: {{ .Flavor }}
2: <?xml version="1.0" encoding="UTF-8" standalone="no"?>
3: < span >Hello< /span >
4: <span>Hello</span>
5: {{ "<" }}span{{ ">" }}Hello{{ "<" }}/span{{ ">" }}
The < on lines 2 and 3 are text. The HTML template package escapes < in text to prevent a document reader from misinterpreting the < as the start of a tag.
The > on lines 2 and 3 is written as is to the output. There is no security benefit to escaping the >.
The < and > on line 4 are part of a tag. Tags are not escaped.
The < and > on line 5 are the value of an expression. The HTML template package fully escapes expression results.
I'm learning to programming and I'm trying to create in a page a list of booking that a user has done.
In particular, I would like to recover all the bookings made by a user using his email
I have create a JSP page:
<body>
<%=session.getAttribute("Nome") +" "+ session.getAttribute("Cognome") + " "+ session.getAttribute("Email") %>
<br>
Prenotazioni Effettuate:
<%
try{
String email=(String)session.getAttribute("Email");
// out.print("Hello "+n);
Class.forName("com.mysql.cj.jdbc.Driver");
// out.println("driver loaded");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/Hotel","root" ,"123456789");
// out.println("Connect");
Statement stmt = con.createStatement();
// out.println("conncetion successfull");
String query="";
String emailp = "";
String arrivdate = "";
query="select * from reservation where email = "+email;
ResultSet r = stmt.executeQuery(query);
while (r.next())
{
emailp = r.getString("email");
arrivdate = r.getString("arrivalDate");
%>
Email: <%= emailp %>
Arrival date: <%= arrivdate %>
<% }}
catch(Exception e)
{
}
out.close();
%>
I don't understand why nothing is printed.
Is it a query problem or a code problem that's wrong? do you know how to help me?

I solved using this way:
String query="SELECT * FROM reservation WHERE email= '" + session.getAttribute("Email") + "'";
The Liberty server starts properly and begins to shutdown withing a second.
The server is being started in eclipse version Juno in my Windows development system. The application is a web application with ejb in it. Server configuration details below.

A couple of things to check -- Do you have application code that is calling System.exit? Are you starting the server without using nohup and then exiting the shell?
I have a table in whose column I show both a image and text.Image is being displayed on upper side and text is being displayed below it.But I want to show both side by side.Moreover I want table to be fit on screen i.e I don't want to have scroll bars.
My Html code is

My output.
I want the second column text and image to be aligned side by side and table to fit the screen.
Thanks in advance.
Got it, just added
display: inline-block
<h2 style="vertical-align:middle; display: inline-block;">
I think it's simpler to break the column with image and text in 2 distinct columns: 1 for the image and 1 for the text. In css you can use: table {width:100%}
Make the following changes in the image tag:
add display:block and add float:left
In the text to show it side by side, just add float:left assuming text is inside a block element like a p tag.
For table to occupy full screen use width:100%;
