Problem when inserting in java

[aleksandar]

Hello
I'm new in Java and i'm updating some code that i inherited.In that code all fields need to be filled. When i insert new field that may be blank i cant write in data base and i get the next error :java.lang.NumberFormatException: For input string: ""
at java.lang.NumberFormatException.forInputString(Num berFormatException.java:48)
on that field i have this code on insert
prstINSERT_GLAVA.setString(colonaGlavaZABELESKA_G, controlZABELESKA_G.getText());
Please help
Thank You

Read the API for the classes/methods you are using. Without code or any more information its a guess, but NumberFormatException's are typically thrown when trying to parse a string into a primitive number value..and will be thrown for an empty string.

The thing is that i enter data for some fields and i skip one and when a try to submit i get that error here is the part of the code when i try to insert

public boolean insertPomagalaGlava()
{
boolean b = false;
try
{
long l = System.currentTimeMillis();

prstINSERT_GLAVA.setLong(colonaGlavaEMBG_PODNOSITE L, Long.parseLong(controlEMBG_PODNOSITEL.getText()));

System.out.println("Kaj Podosnitel");
prstINSERT_GLAVA.setString(colonaGlavaZABELESKA_G, controlZABELESKA_G.getText());
// VARCHAR(20)
prstINSERT_GLAVA.setString(colonaGlavaVRABOTEN, controlVRABOTEN.getText());

prstINSERT_GLAVA.execute();

db.conn.commit();
long n = System.currentTimeMillis();
System.out.println("Insert PomagalaGlava : "+(n-l)+" msec");
return true;
}
catch(Exception exc)
{
exc.printStackTrace();
try
{
db.conn.rollback();
}
catch(Exception e)
{
e.printStackTrace();
}
return false;
}
}//insertPomagalaGlava
The field that can be blank in same cases is controlZABELESKA.Thank You
