How to pass json object with special characters to servlet? - json

I want to pass json values to the servlet to handle the request.
In client side, i could made the object with special character such as "&" .
I have given the input as
"<h3>Welcome to ERP your name is #NAME#</h3>\n\n<h3> </h3>\n"
I retrieve the value from the json object by using
request.getParameter("jsonVal")
by calling like this, the json value after the "&nbsp" , not taken by the servlet. The output is
"\"<h3>Welcome to ERP your name is #NAME#</h3>\\n\\n<h3>
and shows the error as:
org.json.JSONException: Unterminated string at character 206

How to handle this issue?
Thanks in advance..


After getting request.getParameter("jsonVal") , try on a JSON Viewer and identify what is the special character. Carriage return+new line has issues with JSONTokener, so you can trim it if possible and work with it.

That makes no sense because NONE is not even a column... Could I have a corrupted database?
Do I need to declare the NONE as \"NONE\" or as an other type?
Thank you for any help,
Lucas

NONE doesn't mean anything in MySQL. The error message is simply saying "I don't recognize "NONE", so I think it is a column name and it is not".
Perhaps you mean one of the following:
VALUES ('NONE', 4602, 100, 0, 1)
VALUES (NULL, 4602, 100, 0, 1)
VALUES (DEFAULT, 4602, 100, 0, 1)
The first inserts the string 'NONE' into the field; the second a NULL value and the third inserts the default value (if none is defined, then NULL).

your error: Unknown column 'NONE' in 'field list'
put this code in variable e.g.
Str = INSERT INTO Matches_2016_Qualification (Additional_information, Team_number, Points, Auton, Match_number) VALUES (NONE, 4602, 100, 0, 1)
then run to your mysql command line and give us the result.
what is your NONE data type?

This is my requette :
Query req=em.createNamedQuery("LOAD DATA INFILE 'C:/Users/DELL/Desktop/stage11111/Gabits/src/main/test' INTO TABLE Transaction FIELDS TERMINATED BY ';' LINES TERMINATED BY '\r\n'");
Please help me !
Thanks

It looks like you are calling the wrong EntityManager method.
From the JavaDoc of the method you are calling:
Query createNamedQuery(String name)
Create an instance of Query for executing a named query (in the Java Persistence query language or in native SQL).
Parameters:
name - the name of a query defined in metadata
Returns:
the new query instance
What I think you are wanting to call:
Query createNativeQuery(String sqlString)
Create an instance of Query for executing a native SQL statement, e.g., for update or delete.
Parameters:
sqlString - a native SQL query string
Returns:
the new query instance

thanks for reading my problem,may you help me to solve this problem.

org.neo4j.graphdb.TransactionFailureException: Database is currently not available. No blocking components

but all my operations to change the database are in a transction like demo
try (Transaction tx = graphDB.beginTx()) {
//do something
tx.success();
}
How do I use Neo4j connections like MySQL connections?
my environment is Eclipse + Tomcat 7.0 in Java 7
and this is the link of database log https://www.dropbox.com/s/a7858mywidbvr03/messages.log
thank you very much

I'm trying to run BIRT Servlet example:

I think I added all required jars to buildpath of my project but I can't make this thing run for days now.

Is there anything else I forgot to do?
Can you please help me understand this error and running the servlet? Thanks in advance!!

You have to make sure that the JAR file containing the class org.eclipse.birt.report.engine.api.IRenderOption is present inside WEB-INF/lib folder.
