Yaning,

Use JDK 1.4.x with NWDS as well. Otherwise after compilation you get calls inside byte-code to methods that exists only in JDK 1.5 and hence not available at run-time (in JDK 1.4 of server).

You cannot run code that used JDK5 features on a JDK 1.4 server, so goto Window -> Preferences -> Java -> Installed JREs and select JDK 1.4 as default.

It seems there is some JDK5-only code in the tutorial (BigDecimal.ZERO, BigDecimal(0)). This is wrong, simply change it to work with the JDK of the Web Dynpro release.

hi

First intialize the BigDecimal as

BigDecimal var = new BigDecimal("0");

You can pass string to the BigDecimal and can change string into BigDecimal

Hello Yaning.

I had this exact same problem. I opted for using BigDecimal's other constructor the one that receives a String instead of an int:

BigDecimal total = new BigDecimal("0");

This worked out perfectly for me. However it would be nice if somebody could tell us why the constructor that receives an int doesnt work as expected.

Hope this helps

Hi there,

Can you post the line of code in line 162 of TableCompBasketView? Because thats where the error is.

Regards,

LM

[Former Member]

Hi LM,

Thx

public java.math.BigDecimal getTotalPriceAMOUNT(IPrivateTableCompBasketView.ITotalPriceElement element)

{

//begin getTotalPriceAMOUNT(IPrivateTableCompBasketView.ITotalPriceElement)

//line 162

BigDecimal total = new BigDecimal(BigInteger.ZERO);

int n = wdContext.nodeProducts().size();

for (int i = 0; i < n; ++i) {

IProductsElement item = wdContext.nodeProducts().getProductsElementAt(i);

int quantity = item.getQUANTITY();

BigDecimal price = item.getPRICE();

total = total.add(new BigDecimal(BigInteger.valueOf(quantity)).multiply(price));

}

return total;

}

Hi,

chaage this and try

BigDecimal total = new BigDecimal(BigInteger.ZERO);

// u try use this code.

BigDecimal total = new BigDecimal(0);

int n = wdContext.nodeProducts().size();

for (int i = 0; i < n; ++i) {

total =

total.add(

new BigDecimal(wdContext.nodeProducts().getProductsElementAt(i).getQUANTITY()).multiply(

wdContext.nodeProducts().getProductsElementAt(i).getPRICE()));

}

return total;

//@@end

}

Thanks,

Lohi.

Hi,

Otherwise do one thing re-download once and try to deploy.

then it might helps you.

Thanks,

Hi,

In a big decimal u can try passing a string and multiply.

try this:

public java.math.BigDecimal getTotalPriceAMOUNT(IPrivateTableCompBasketView.ITotalPriceElement element)

{

//begin getTotalPriceAMOUNT(IPrivateTableCompBasketView.ITotalPriceElement)

BigDecimal total = new BigDecimal("0");

int n = wdContext.nodeProducts().size();

for (int i = 0; i < n; ++i) {

IProductsElement item = wdContext.nodeProducts().getProductsElementAt(i);

int q = item.getQUANTITY();

String qty = null;

BigDecimal quantity = new BigDecimal(qty.valueOf(q));

BigDecimal price = item.getPRICE();

total = total.add(quantity.multiply(price));

}

return total;

}
