JRE 1.4.2 to 1.5 Migration issue in XML

[Varatharajan Irusappan]

Hi all,

I am facing a problem in compatibility between JRE 1.4.2 and JRE1.5.0
Hope someone can help me in solving this issue.

I have an XML as described below.

<test>
<LogType type="string">Audit</LogType>
<maxMOCount type="uint32">30</maxMOCount>
<LogSize type="uint32">10489</LogSize>
<test type="string">abc defghijklmnopqrstuvwxyz</test>
</test>
Note:
=====
1.There are two test elements one containing the other.
2.The value of the second test element contains two whitespaces in it.


While using JRE1.4.2 the value of the internal test element is returning properly (with two whitespaces in between) with or without the crimson jar in classpath (since JRE 1.4.2 uses crimson jar by default)
So the output is abc<blank space1><blank space2>defghijklmnopqrstuvwxyz.

While using JRE 1.5.0 the value of the internal test element is returning null without the crimson jar in classpath and more surprisingly when the crimson jar is in classpath one of the two whitespaces vanishes.
Now the output is abc<blank space1>defghijklmnopqrstuvwxyz.

Has anyone faced similar issue while migrating from 1.4.2 to 1.5.0

Varath

Hi,

Welcome to JavaRanch!

I suspect that you'll need to tell us a bit more about how you're accessing your XML file -- i.e., show us a little code.

Hi here is the code snippet that you can use to reproduce the issue I said.
Herewith I have attached two class files XMLGetter.java and TestCursor.java
