How to include the mysql-connector in a simple .jar file
Well I started up with java again. Just messing around. This project I'm making now is just plain simple, I have a program thats going to read a table in a database from a server I have here at home. It works fine if I do like this: java javafil to run the file, it reads from the database fine.
But when I made a .jar file out of it using this command: jar cmf manifest.txt javafile.jar *.class
It won't connect to the database. Or it doesn't print out the rows in the table. So I thought I have to include the mysql-connector with the .jar.
manifest.txt
Main-Class: javafile
Now what is an easy way to do this?
This program is also going to be run from a computer that might not have the mysql-connector installed on the computer. Like a friend of mine wants to connect to the database and read it.
I've tried to google "mysql connector in a .jar file" but I get tons of informations about the mysql-connector.jar instead of what I'm looking for.
Thanks,

Yeah but the other computer might not have that connector file on their computer. So is there like I way I can use it when it is in the .jar file? Thats kinda what I wanted. You cannot include another JAR in a JAR file. You however can extract it and put the classes in your JAR. Verify the license agreement if it is allowed. Although this is considered as a bad practice (poor upgradebility and maintainability).
If you don't want to use the -cp parameter, then use the class-path entry of the manifest.mf of your JAR. You can also write a batch file with the whole JAR -cp command in a single line and run the batch file instead.
Pluss, even though I have the right classpath in the environment variables set, it doesn't work for me either. So I guess it doesn't load the connector when running the .jar file.The classpath environment variable has nothing to do with running JAR's. Forget about it and use the -cp or -classpath parameter.

How to include a JSP page contained in a JAR file ?
Hello,

Could someone help me please ?
Thanks in advance.
bgOnlineI don't think thats possible with the standard j2ee server.
There are probably ways around it, but it would involve a large component of custom coding. -

You can access the above mentioned par file from this location,

htp.p('location.href = document.getElementById(href).value;');
htp.p('P8_URL1:= location.href');

How to include the first row of detail in every xquery transformed xml?
I am dealing with a XML file,where i need to publish to different BS.
First node will be a common node node which contains vital info,second node goes to one BS and third goes to another BS.
*<header></header>*
*<details></details> (they are unbounded, but the first detail tag which comes in the input file is a mandatory tag in such a way that it needs to be included in every transformed message)*
*<trailer></trailer>*
We need to apply x query transformation on it in such a way:
*</header></header>*
*<1st detail></1st detail>*
*<detail></detail> (2nd row of detail in input file)* -------------------------> Goes to BS1
*<trailer></trailer>..*
*<header></header>*
*<1st detail></1st detail>*
*<detail></detail> (3rd row of detail in input file)* ----------------------------->Goes to BS2
*<trailer></trailer>*..
And so on.
Now, the problem is how to include the first row( *1st detail* ) of detail in every xquery transformed xml?are you looping of this input with a for each?
/yourdata/details[1] should return always the first detail element.
or before the for each do an assing of this first detail element to "generic_details_var"
and use this var in every looping iteration (in an assign or as input for xquery) -
How to include the promotion and sales deal in the value contract ?
Question : Can a value contract contain other special pricing agreement ?
If yes, how to include the promotion and sales deal in the value contract ?
Thanks for your input.
OscarHi Oscar,
I have not worked on this aspect as such but once you create a value contract I think you as well create a promotion and sales deal for the customer with whom you have value contract with in the validity period of the contract and system should pick up data accordingly as the customer is same (Contract) and is within the validity period.
Pl give feed back.

How to include the file name as an XML field
Hi,
I'm using a file adapter for process a flat file and convert it into an XML. Does anybody knows how to include the file name into an XML field.
Ex.
I process the file named <b>XXIMN21022007.txt</b> and I need an XML like:
<MT_FILE>
<field1></field1>
<field2></field2>
<field3></field3>
<filename><b>XXIMN21022007.txt</b></filename>
</MT_FILE>
Regards
GonzaloJust go for dynamic configuration.
Check the sender file adapter to write the filename in the header (as explained in Michal's blog) and then read that header in some mapping.
U can use that even in simple message mappings.
http://help.sap.com/saphelp_nw2004s/helpdata/en/43/03612cdecc6e76e10000000a422035/frameset.htm
Your code for the filename tag would be something like:
<i>DynamicConfiguration conf = (DynamicConfiguration) container
.getTransformationParameters()
.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create(
http://sap.com/xi/XI/System/File,
FileName);
return conf.get(key);</i>

Henrique.
