Java Security

Hi friends! I have a modern certificate FNMT Clas 2, extension pfx. I can't load this certificate in a linux ibm server with java 1.4 but it works in java 1.6 in windows operating system.

In linux i have:

/usr/local/java/bin/keytool -list -keystore /mycerts/andel.cer -storetype pkcs12

Error de keytool: java.io.IOException: DerInputStream.getLength(): lengthTag=127, too big.

I have tried with java program instead the keytool, and the error it's the same:

java.io.IOException: DerInputStream.getLength(): lengthTag=127, too big.

Works in windows + java.16 and not linux ibm java 1.4?? I think it's a security problem. I need that works with linux server 1.4 java, you have any solution?? I need to change java.security or change some jar packages??

Thanks a lot
